Description

Integrated memory card reading and recording device

The present invention is a "single memory card reading and recording device" which is built in or external to a computer system or other electronic products, and is capable of reading and recording memory cards of various specifications with one or two slots. It can meet the demands and solve the problems of confusion, mistakes and damage caused by three or more slot designs at the same time.

A memory card reading and recording device is a device that uses a kind of potable storage memory cards that can be read and recorded. It is widely applied in the Information Appliance (IA) and various portable digital products. For example, most popular products such as PDAs, digital cameras (DSCs), and digital walkers (MP3 Players) use memory cards as storage media.

However, due to IA's emerging field, the product has been very new and diversified, and memory card is one of the fields that compete in the international conglomerates to develop and secure a priority position in the market. Currently, the production of memory cards around the world does not have a completely unified standard and standard, so related products are plural and have their own market share. However, due to the lack of conformity of the memory card standard, it is difficult for various types of memory cards to secure effective distribution in the use of different products, that is, portable digital products, computer systems and computer peripherals, which causes inconvenience to consumers. .

The following is the situation of various memory cards currently in circulation.

1.PC Card (PCMCIA ATA Flash Card)

The standard of PC Card is the memory card exclusive standard established by PCMCIA. This standard is 85.6mm in length and 54mm in width, and Type I (3.3mm) and Type II (5.5mm) depending on the thickness. There are three types of Type III (10.5 mm), and they are mainly applied to notebook computers (NB / potable computers).

2. Compact Flash Card

CF card is a kind of very light and small memory card. Its size is 43mm in length and 36mm in width and it can be divided into two types, Type I (3.3 mm) and Type II (5 mm). Light weight, excellent data preservation, and high reliability and power saving, so it is widely used in consumer electronics. Mostly peripheral equipment of IA products such as PDA, digital camera (DSC), digital worker (MP3 Player) It is applied to.

3.SM Card (Smart Media Card)

SM card standard is only 0.76mm thick, and the manufacturer uses a flash memory directly to package it into a special card. The electrical interface and the manufacturer's flash memory are the same and are mainly applied to digital cameras and digital workers.

4. MMC card (Multi Media Card)

The specification of MMC card is the smallest external memory card on the market, and it has a thickness of 1.4mm and adopts a parallel interface.

5. MS Card (Memory Stick Card)

The appearance of the MS card is about the size of a single gum and employs a parallel interface. The patent for this memory card is granted to each company exclusively by SONY. Currently, the only products that apply to MS card in the market are those developed and sold by SONY, which is applied to mobile phones and personal computers that can be used on the Internet in combination with digital cameras, digital workers, PDAs and workers. .

6.SD card (Secure Digital Card)

The thickness of the SD card is 2.1 mm and the rest of the external size is the same as the MMC card, and also uses a parallel interface, and is mainly applied to products such as digital workers, digital cameras, and PDAs.

As mentioned above, due to the different sizes of memory cards, it is difficult to respond quickly to the trend of rapid development of the information industry and home appliances, and the inconsistency of the memory card standards is appropriate for various memory cards in order for each company to meet the market demand. Memory card reading and recording devices have been produced. However, due to the diversification of the memory card standard, manufacturers of memory card reading and recording devices have supported different types of memory cards with different specifications by increasing slots in the memory card reading and recording devices. For example, a memory card reading and recording device having three slots (supporting three types of memory card specifications) and four slots (supporting four types of memory card specifications).

Although the manufacturing method and structure of the conventional memory card reading and recording apparatus of a plurality of slots can solve some of the difficulties in which the memory card specifications are not uniform, however, it causes more problems and inconveniences for the user. Sometimes. For example,

1. Excessive slots can lead to congestion. For example, when a user's memory card reading and recording device has four slots, it supports four types of memory cards, such as SM, MMC, MS, and SM. The recording device displays only a number of slot indicators such as F slot, G slot, H slot, and I slot on the monitor after the system is turned on, and does not display the division of SM slot, MMC slot, MS slot, and SD slot. Cannot easily determine which type of memory card has already been inserted into the slot, thereby causing confusion in use.

2. Excessive slots cause inconvenience. In these cases, this memory card reading and recording device must be designed to support the IDE / ATAPI family of interfaces. However, when connecting to a main system, only two slots can be active simultaneously for a four-slot memory card reading and recording unit (IDE / ATAPI supports only two sets of different signal processing lines in support of the main unit). The other two slots become useless, which can cause the slot to become inoperable or even freeze when the user attempts to retrieve and record a third memory card at the same time. .

3. In addition, for example, excessive slots may be inserted incorrectly by the user, or incorrect insertion may damage the memory card or the slot itself, such as high manufacturing costs, excessive volume, poor built-in support, etc. It is a drawback of conventional memory card reading and recording apparatus with slots.

In view of the above-mentioned drawbacks of the prior art, the present invention relates to a type of "unified memory card reading and recording device" for solving the non-uniformity problem of the memory card standard, which solves various conventional problems. .

Specifically, the "unified memory card reading and recording device" of the present invention mainly inserts an existing similar size SM, MMC, MS and SD card into one slot, CF card TYPE I, TYPE II, or PC card TYPE I. , TYPE II and TYPE III can be inserted into different slots, thereby reading and recording the files of any of the above-mentioned memory cards, and also by adding the design of an IDE / ATAPI, USB, PCMCIA or 1394 transfer cable, The memory card reading and recording device, which is designed with two slots, inserts all currently available memory cards for reading and recording.

An object of the present invention is to support a variety of memory card specifications simultaneously as a memory card reading and recording device of the one or two slot design described above, and various memory cards are simpler and more convenient in a variety of portable products, It is to provide a user with the best convenience by allowing a fault-free exchange to be made to personal computers and computer peripherals, and at the same time to compensate for various shortcomings of the prior art, such as confusion, mistakes and damage.

Another object of the present invention is to add the design of IDE / ATAPI, USB, PCMCIA or 1394 transmission cable at the same time as the simplified design of the present invention, so that memory card reading and recording devices can be easily embedded in various computer main systems or related peripherals. Or it can be external to meet the needs of various consumers, thereby integrating the memory card of various standards to meet the market distribution structure of the memory card reading and recording device.

In addition, the de-standardization of memory card standards has prevented system manufacturers from making progress in embedding memory card reading and recording devices into computer systems, which indirectly leads to confusion of various memory cards, leading to consumer interests. Infringed. This phenomenon can be solved by the present invention `` unified memory card reading and recording device '', because the current non-standard memory card can overcome all the technical problems of the system built-in through this design It is a great interest for system companies and consumers.

50: Transmission cable 60: Memory card

As shown in Fig. 1, the present invention "unified memory card reading and recording device" can be embedded in a computer main body system 10 or other electronics (not shown), the main compositional requirements of one main body 20, a first outlet 30, a second outlet 40, and one transmission cable 50. Among them, the outer shape of the main body 20 is designed in a rectangular shape suitable for coupling with the computer main system 10 or other electronic products, and the inside thereof has a receiving space, which is used for accommodating circuit boards and other electronic units. The first slot 21 and the second slot 22 are located at one side of the main body 20, respectively. By this structure, the memory card 60 is conveniently inserted into the first slot 21 and the second slot 20, respectively. In addition, the first outlet 30 is installed in the main body 20 and corresponds to the position of the first slot 21, and the second outlet 40 is also installed in the main body 20 and the position of the second slot 22. Corresponds to. Accordingly, when the memory card 60 is inserted into the main body 20 through the first slot 21 or the second slot 22, the memory card 60 is connected to the first outlet 30 or the second outlet 40.

As shown in FIG. 2, the shape of the first outlet 30 is slightly "U" shaped and has an engagement region 31 in the middle portion, which has at least four pairs of length and width. The other leading slots 32 are provided, which lead to SM cards, MMC cards, MS cards, and SD cards, which are similar in size, respectively, of the memory cards 60. Of any one of the cards) is inserted into the engagement area 31 by the leading slots 32 corresponding to each other, and is coupled to the first outlet 30 at the same time. After the memory card 60 is coupled to the first outlet 30 and fixed, the memory card 60 is immediately transmitted to the circuit board in the main body 20 as a mutual transmission signal to proceed with the reading operation (but this is not the focus of the present invention. As not described in detail in the present invention).

In the same principle, the manufacturing principle of the second outlet 40 as shown in FIG. 3 is the same as that of the first outlet, and also the leading slot 32 having a different length and width of the engagement area 31 and a plurality of pairs. A memory card 60 (only one type is shown in the drawing) of type I, Type II, and Type III having different thicknesses is coupled to the second outlet 40. Similarly, after the memory card 60 is coupled to the second outlet 40, the mutual transmission signal is immediately transmitted to the circuit board in the main body 20. It should be emphasized that the memory card 60 is a PCMCIA interface type memory card (PC ATA Flash Card) or a PCMCIA interface switch adapter (Adapter). The PCMCIA interface switch card is also used for other types of memory cards, For example, it can be inserted into four types of cards such as SM / MMC / MS / SD (this part has been applied for patent by the inventor and already registered as Japanese Utility Model No. 3079263). Do.

Referring again to FIG. 1, the aforementioned transmission cable 50 is mainly connected to the computer main body system 10 and the main body 20, thereby transmitting signals. After the memory card 60 is inserted into the main body 20 through the first slot 21 or the second slot 22, the circuit board pre-installed in the main body 20 is a file stored in the memory card 60. And simultaneously transmit to the computer main body system 10 via the transmission cable 50, the information transferred to the computer main body system 10 is stored in the memory card 60 via the transmission cable 50 to the memory The card 60 is read and recorded, and an input / output function is executed.

It should be emphasized that the main body 20 as shown in FIG. 1 is embedded in the computer main body system 10 or other electronic products, wherein the transmission cable 50 is an IDE / ATAPI interface standard (this is an existing technical standard). It is preferable to connect. In the design of the transmission cable 50 of the IDE / ATAPI interface standard, the internal processing is a principle. However, even in support of a computer main body system, every single stranded cable provides only the different signal processing of the two modifications (this is Master, Slave). By the provisions of the structure). In other words, a conventional conventional three or four slot memory card reading and recording device also supports the IDE / ATAPI system interface specification, but in practice the machine only ranks the other two types of first and second. By supporting only card insertion of a standard, a phenomenon in which the third or more types of memory card signals cannot be processed or even a computer freezes may occur.

However, the design of the first and second outlets 30, 40 of the present invention conforms to this standard, and the first and second outlets 30, 40 of the present invention, although the various types of memory card 60 Although it allows the insertion of only one type of memory card 60 can be accommodated at a time, each of the two types of memory card 60 can be inserted at the same time into the maximum two slots. In this way, it is possible to prevent a signal processing problem or a computer freeze which occurs when the third type of card is inserted into the above-described three or four slot memory card reading and recording apparatus.

In other words, the present invention has a much wider use space than a conventional memory card reading and recording device having three or four slots (the present invention has SM, MMC, MS, SD card and PC card TYPE I, TYPE II, Seven types of memory cards, such as TYPE III, can be used, whereas conventional three or four slot memory card reading and recording devices can only insert three or four types of cards.) Even if three or more types of cards are inserted at the same time, the computer does not pause. This is also a feature of the present invention.

In addition, the embodiment shown in Figures 1 to 3 is a schematic diagram showing that the main body 20 is directly embedded in the computer main body system 10, or other electronic products when the present invention is implemented, a computer currently on the market Transfer cables 50 are also designed to interface standards (such as USB or 1394) (shown in FIG. 4) for users who are fitted with a main body or other electronics and also cannot incorporate the main unit 20 via a USB or 1394 interface. ) To an external computer to read and record the memory card.

As shown in FIG. 5, the implementation of the present invention is not limited to two slots, but a single slot can be designed. Basically, the main body 20 is equipped with a first slot 21, a first outlet 30, and a transmission cable 50 which can be arranged differently depending on necessity. Different kinds of memory cards can be read and recorded.

In addition, the above-mentioned second slot is designed to meet the three types of PC card types TYPE I, TYPE II, and TYPE III. At the time of implementation, two types of standards of CF card TYPE I and TYPE II can also be used. I will not explain.

The names of the various units described above are convenient for the purpose of describing the technical contents of the present invention, but are not limited to the present invention. Corrections and modifications within the spirit and scope of the present invention are also within the scope of protection of the present invention, and their rights are based on the scope defined in the following claims.
