Description

The invention relates to devices for projecting images onto a viewing surface, namely, a book with a built-in projector for demonstrating slides while reading informational support.

Known book projector slide, consisting of an optical unit, which includes many light sources and the corresponding array of lenses. Moreover, each lens and the corresponding light source is adapted for showing slides located between them. In addition, the book contains a control unit with switches, each of which activates a corresponding light source (according to patent US9675901 B2, class А63Н 33/38, G03B 21/00, publ. 06/13/17).

The disadvantage of this device is the design complexity associated with the fact that each slide uses its own light source, as well as the lack of synchronization of book pages and slides.

A device for reproducing filmstrips is known, characterized in that it contains a slide projector, a remote control, a storage medium including a set of slides, a digital medium with an audio version of a book and a booklet with signatures for the filmstrip and labels for the remote control to work. The slide projector is equipped with a unit for installing a cartridge and a digital medium with an audio version of a book, a device for reading and playing sound files from a digital medium with an audio version of a book, a unit for placing batteries, a speaker, a projection lens and an infrared sensor (according to patent RU108159, class G09B 21/00 , publ. 09/10/11).

The disadvantage of this device is the design complexity associated with a large number of components included in its composition.

The closest technical solution is a book-video projector slide, which consists of interconnected front and back covers with pages inserted between them. The book has a video projector that reproduces slides from an external source (according to patent US7217055 B2, class B42F 13/40, G09B 17/00, publ. 05.15.07).

The disadvantage of this device is the lack of synchronization of the pages of the book and slides, which makes it inconvenient to use.

The technical result of the invention is to improve ease of use and simplify the design.

The specified technical result is achieved in that the book-slide projector contains a projector and a cartridge book attached to it, and is characterized in that the cartridge book consists of at least two sheets with a jumper connecting them with a translucent element.

In the particular case of the product, the projector is made integral with the cover for the book cartridge.

In the particular case of the product, the cartridge book is mounted on the projector by means of a device for fixing the page turning axis in the form of an O-shaped clamping ring mechanism.

In the particular case of product execution, a movable mirror element is installed in the projector.

In the particular case of product execution, a microswitch activated by a translucent element is provided for turning on the projector.

In the particular case of the product, the projector is equipped with a power source mounted on the cover, made in the form of a battery / battery pack with charger.

In the particular case of product execution, a lantern is mounted on the power supply housing to illuminate the pages.

In the particular case of the product, the lantern is fixed pivotally.

In the particular case of the product, the lamp housing performs the function of a switch of the lamp itself and the projector.

In the particular case of the product, the cartridge book can be removed from the projector and replaced with another cartridge book.

In a particular case, an LED with a lens is used as a light source in the emitter.

The invention is illustrated by the following drawings:

Figure 1 - the main components of the book-slide projector;

Figure 2 - book slide projector assembly;

Figure 3 - view of the book-slide projector when turning pages;

Figure 4 - book slide projector in working position;

Figure 5 is a cross-sectional book-projector.

The slide projector (Fig. 1) consists of the following main components: the cover of the projector 1 and the cartridge of the book 2. The set of products may include several replaceable cartridge cartridges, including those with various information and graphic contents.

The presented drawings suggest a special case of an embodiment of the invention in which the cover-projector 1 consists directly of cover 3 (Fig. 2) and a projector mounted in its spine, consisting of a coaxially mounted emitter 4 and an optical unit 5.

The cartridge book 2 is fixed in the device for fixing the page turning axis 6, made in the form of an O-shaped clamping ring mechanism mounted on the emitter body 4. The longitudinal axis of the ring mechanism is parallel to the axis of the emitter beam. A power supply 7 is fixed on the cover 3. The kit may also include a unit for charging the power supply 8.

A lamp 9 is pivotally mounted on the housing of the power supply 7. The housing of the lamp 9 performs the function of a rotary switch. The function of the switch can be provided by a sliding conductive segment fixed at the axis of rotation in the lamp housing and closing the circuit break in the reciprocal contact path fixed in the housing of the power source.

The sheets of the cartridge book 2 are interconnected along the axis of turning. On the upper cut adjacent sheets are connected to each other by a jumper 10 (Fig. 3) with a translucent element 11, which contains graphic information.

Cartridge-book 2 has a folding design, the feature of which is the property in which when turning pages with the achievement of adjacent odd and even pages of a 180-degree spread. the jumper 10 connecting them reaches a position perpendicular to them (Fig. 4). In this case, when the cartridge book is mounted on the projector, the translucent element 11 is at the place required for achieving a clear projection in the receiving window of the projector (Fig. 5).

The material of the pages of the cartridge book 2 and the segment of the jumper 10 containing the translucent element 11 must have relative rigidity to maintain functionality.

The pages of the cartridge-book 2 and the jumper 11 may contain text and (or) graphic information, including the corresponding content of the projected image.

In the housing of the optical unit 5, a movable mirror element 12 is installed.

A microswitch 13 is mounted on the housing of the optical unit 5.

The procedure for using the slide projector is as follows.

When the cover 3 is opened, access to the components of the product is opened. If the cartridge book 2 is not fixed in the fixing device 6, it is necessary to squeeze the half rings of the clamping mechanism to the sides, insert the cartridge book 2 so that the half rings fit into the corresponding notches of the book cartridge 2 and snap the half rings.

To turn on the projector, turn the lamp housing 9 into the working position. This closes the circuit supplying power to the lamp itself and to the microswitch 13.

When expanding the pages until the angle between them reaches 180 degrees. the jumper 10 connecting them reaches a position perpendicular to them, at which the translucent element 11, pressing the lever of the microswitch 13, is at the place required for achieving a clear projection in the receiving window of the projector. In this case, a normally open microswitch 13 closes the circuit supplying power to the emitter. Depending on the position of the raised or folded mirror element 12 (Fig. 5), the beam containing the projected image will be directed upward (Pos. I) or directly (Pos. II). During the projection time of the image, it is possible to read the illuminated flashlight 9 textual and (or) graphic information from the opened pages.

The most sought-after is expected to use a book projector when reading fairy tales before bedtime for a child lying in bed, with the projection of accompanying pictures on the ceiling above the bed.

Thus, in the most complete package, the product can be presented as follows: it consists of a projector made at the same time with a cover on which a power source with a backlight is fixed, the projector consists of a coaxially mounted optical unit with a movable mirror and an emitter, a device is mounted on the projector fixation, in which the cartridge-book is fixed, the sheets of which are interconnected along the axis of turning and have jumpers containing translucent elements (transparencies, slide s) with graphic or textual and graphic information, while the jumpers have a folding feature in which a translucent element falls into the region of the light flux when the pages are turned 180 degrees. A charger may be included with the power source.

Using the product leads to the projection of the image on the screen, which can be a wall or ceiling.
