More specifically, the present invention relates to a display device and a stand of which the convenience of use of the auxiliary memory device is improved in a display device in which the auxiliary memory device is embedded in the display device to implement the PVR function.

The general PVR function is already well known. In brief, the PVR function is a function that stores a certain signal in real time with a large capacity of its own auxiliary storage device inside the electronic device, and allows the user to read and play the stored signal according to a desired progress situation. to be. A representative example of implementing such a PVR function is a television, and as another apparatus, an image storage device storing an acquired image of a blocking circuit for home security is an example. The present invention is primarily concerned with the manner in which the PVR function is implemented in a television that is a display device.

In order to implement a PVR function by a display device, a hard disk (hereinafter referred to as a hard disk drive (HDD)), which is an auxiliary storage device, is internally embedded in a television, and a broadcast signal is controlled by a predetermined control unit that controls the hard disk. The lamp shall be stored or regenerated. In recent years, the PVR function of the television has been increased due to the increase of the capacity of the hard disk and the development of file compression technology.

However, a hard disk fixedly embedded in the display device has a disadvantage in that the stored video is only viewable by the current image device, that is, the display device itself as the hard disk is embedded.

In addition, since the capacity of the built-in hard disk is limited, the capacity of the image that can be stored is also limited, so that the user can store the image only for a specific time.

In addition, with the development of the technology of the hard disk field, even if a high capacity hard disk is developed, only the hard disk built in the manufacturing of the display device can be fixedly used, and the process of replacing it is fundamentally impossible. There is this. Furthermore, there is a disadvantage that the process of additionally installing a hard disk is also impossible.

In addition, in order to reduce the cost at the time of purchase, a purchaser who does not purchase a hard disk-integrated display device at the time of purchase cannot use the PVR function until he / she purchases an expensive television thereafter.

Referring to FIG. 5, the HDD cartridge 3 is shaped like a hexahedron and has an HDD 7 mounted therein. In addition, an opening is formed at one side of the HDD 7 so as to protrude the power terminal 72 and the signal terminal 71. In addition, a pair of fixing grooves 31 are formed on the side of the HDD cartridge 3 so that the position of the HDD cartridge 3 can be fixed by the locker 6.

Although the detailed description is not given, at least one surface of the HDD cartridge 3 is preferably opened and closed smoothly so that the insertion operation of the HDD cartridge 3 occurs smoothly. The HDD 7 can be inserted through the opened one surface. Of course, after the HDD 7 is inserted into the HDD cartridge 3, it is preferable that the open one surface is closed so that the inserted HDD 7 is not detached.

FIG. 6 is a view illustrating an operation in which the HDD cartridge is inserted into the HDD mounting unit. In FIG. 6, the internal structure of the holder 5 is not shown in detail. However, this is to prevent the complexity of the drawing. Inside) each component shown in FIG. 4 is included. The same is true of FIGS. 7 to 8.

Referring to FIG. 6, the HDD cartridge 3 is inserted into the HDD mounting unit 8 in the state guided by the insertion guide 4. Although the insertion guide 4 is introduced in the figure in the shape of a wall provided on the upper side and the lower side in the insertion direction of the HDD cartridge 3, it is not limited to this shape, and various shapes such as a roller structure, etc. It may be presented as.

Then, when inserted beyond a predetermined depth, the inclined surface 61 of the rocker 6 touches the insertion end of the HDD cartridge 3 so that the rocker 6 is rotated in the opening direction.

Subsequently, when the HDD cartridge 3 is inserted beyond a certain depth, the signal terminal 71 is fitted to the signal connector 57, and the power supply terminal 72 is fitted to the power connector 59.

The signal connector 57 and the power supply terminal 72 are formed to be connected to the internal parts of the display device through the support of the stand.

With this configuration, simply attaching the HDD 7 to the HDD mounting unit allows the connection between the HDD 7 and the display device 1 to be completed, so that signals can be transmitted between the two, so that the image information can be transferred to the HDD 7. The information stored in the HDD 7 may be transferred to the display device 1.

At this time, in order to improve the reliability of the connection between the terminal 71, 72 and the connector 57, the insertion position of the HDD cartridge 3 is guided to the correct position by the insertion guide (4) Preferably, the connector 57, 59 is preferably firmly fixed by the holder (5).

7 is a view for explaining a state that is completely mounted inside the HDD cartridge and the HDD mounting portion.

Referring to FIG. 7, as described above, the connection between the terminal and the connector is completed, as well as the rocker 6 is rotated by using the solenoid 51 as a driving source to the inside of the fixing groove 31. The locking end is inserted. Therefore, once the locker 6 is caught in the inside of the fixing groove 31, the HDD cartridge 3 does not fall out even by an external force.

In order to operate the rocker 6 in this manner, the solenoid 51 for operating the rocker 6 in the insertion process of the HDD cartridge may be operated in the following process.

First, when the HDD cartridge 3 is caught by the rocker 6 and the rocker 6 is rotated at a predetermined angle, that is, there is no operation by the solenoid 51, that is, the rocker 6 is not provided with an external force. Is freely rotated at an angle, that is, counterclockwise (in the upper rocker). Of course, the rocker 6 is rotated because the inclined portion 61 is pushed to the insertion end of the HDD cartridge 3 when the HDD cartridge 3 is inserted.

Second, when the HDD cartridge is fully inserted, power is applied to the solenoid 51 to push the rack 52 upward with a constant force. Then, the rocker 6 (the upper rocker on the basis of the drawing) is rotated in the clockwise direction so that the locking end of the rocker 6 is caught in the fixing groove 31 so that the position of the HDD cartridge 3 is fixed. The HDD cartridge 3 is not detached even by external force.

Here, the operation of detecting that the HDD cartridge 3 is completely inserted may be performed by detecting the connection state between the terminals 71 and 72 and the connectors 57 and 59 by the controller of the display device. .

As yet another embodiment, it is necessary to apply power to the solenoid 51 by essentially providing a force in which the rocker 6 rotates counterclockwise through an elastic member at the end of the rocker 6. When the end of the rocker 6 reaches the position of the fixing groove 31 without being able to be caught between the rocker 6 and the fixing groove 31 by the force of the elastic member. In addition, when the rocker 6 is completely mounted, it is also possible for the user to manually rotate the rocker 6 so that the rocker 6 can be caught in the fixing groove 31. Of course, various other aspects are also possible, but the end of the locker 6 is caught in the fixing groove 31 so that the position of the HDD cartridge 3 to be fixed inside the HDD mounting part 8 is to be fixed. Of course.

8 is a view for explaining the detachment operation of the HDD cartridge.

Referring to Fig. 8, when the user presses the eject button 9 to pull out the HDD cartridge 3, the rack 52 is pulled downward by the solenoid 51 (lower solenoid).

The operation by the eject button may be performed by the controller of the display device.

In more detail, referring to FIG. 9, when the eject button unit 91 is operated, a signal is detected by the control unit 92 of the display device, and the control unit 92 controls the drive unit 93 to control the HDD cartridge. A series of operations to depart (3) is performed. It goes without saying that the solenoid 51 is included in the driving unit 93.

After the operation of the eject button unit 91 is performed, a series of operations performed by the solenoid 51 is as follows.

First, the pinion 53 meshed with the rack 52 and the rocker 6 integrally operated with the pinion 53 are rotated clockwise (in the upper rocker). Then, the rocker 6 is released from the fixing groove 31, and the fixing action of the HDD cartridge 3 is released.

Second, when the fixing action of the HDD cartridge 3 by the rocker 6 is released, the HDD cartridge 3 is pushed outward by the elastic member 10.

Third, if the solenoid 51 continues to be pushed downward even after the locking operation of the rocker 6 and the fixing groove 31 is released, the pushing arm 55 continues to rotate clockwise to push. By the arm 55, the HDD cartridge 3 is pushed outwards to be more outward. As such, it is preferable to release the connection state between the terminals 71 and 72 and the connectors 57 and 59 by the pushing force of the pushing arm 55.

Meanwhile, in order to smoothly remove the HDD cartridge 3 by the pushing arm 55, the pushing arm 55 is mounted on the HDD cartridge 3 while the HDD cartridge 3 is mounted. It is desirable to maintain a constant interval without contacting In other words, the pushing arm 55 should not push the HDD cartridge 3 until the locking state between the rocker 6 and the fixing groove 31 is released.

Fourth, even after the connection state between the terminal and the connector is released, the force by the elastic member 10 is continuously applied to the HDD cartridge 3 within a certain distance. Therefore, the user can remove the HDD cartridge 3 more conveniently.

The above four steps may be performed in a reversed order. For example, the pushing force of the elastic member 10 may be applied even before the fixing action between the rocker 6 and the fixing groove 31 is released. It is natural to lose.

However, in order for the HDD cartridge 3 to be pulled out, the locking action between the rocker 6 and the fixing groove 31 is released, and the elastic member 10 pushes the HDD cartridge 3 outward. Naturally, the pushing arm 55 pushes the HDD cartridge 3 outward.

By the above description, the operation of accommodating or detaching the HDD cartridge inside the base of the display device will be clearly understood. Hereinafter, the internal operation of the HDD cartridge will be described in detail.
