Description

  The present invention relates to a picture book type projection toy.

As a picture book with sound, a sound picture book with sound storage device, sound generator, power supply, and switch on the front cover and / or back cover, and by pressing a designated place on each page of the picture book It is known that a switch below the designated location provided on the front cover and / or back cover is pressed to generate sound corresponding to the designated location. (For example, Patent Document 1)
JP 2000-84266 A

  In the latter picture book, there was a problem that it was necessary to move the hand greatly in order to turn the page, to hold down the turned page, and to apply dynamic because the screen was small.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a picture book type projection toy that is easy to operate and enjoys dynamic images.

  The picture book type projection toy according to claim 1 is detachable from a film cassette provided with a film having subtitles and a film that carries a large number of frame images with different scenes. A toy body provided with projection means for illuminating the film and projecting the frame image as a light image, and an operator for switching the frame image to be projected by feeding the film; The film cassette is provided with storage means for storing sound data corresponding to at least some of the plurality of frame images, and is present at the projection position. The sound is based on the sound data corresponding to the frame image to be output. The “sound” in this case may be configured to be output by manually operating an operator such as a voice button, or may be automatically output when a frame image comes to the projection position. It may be. Also, the type of “sound” may be a subtitle reading, narration or sound effect. Furthermore, the “sound effect” may be an imitation voice, an onomatopoeia, or the like that shows a scene. Examples of onomatopoeia include dog and bird calls, and examples of onomatopoeia include the sound of thunder, the sound of jumping into the water, the sound of the wind, and the sound of the river.

  The picture book type projection toy according to claim 2 is the picture book type projection toy according to claim 1, wherein the sound data corresponding to the frame image existing at the projection position based on the film feed amount from the predetermined position of the film. It is characterized in that it is determined. As an example of the “predetermined position” in this case, the projection position (initial position) of the first frame image can be considered.

  The picture book type projection toy according to claim 3 is the picture book type projection toy according to claim 1, wherein the sound data corresponding to the frame image existing at the projection position is detected by detecting the index attached to the film. It is characterized by being indexed. In this case, it is necessary to attach a different “index” for each frame. An example of the “index” is a barcode, but it is not necessarily a barcode. Any index that can be detected optically can be used as an “index”.

According to the first to third aspects of the present invention, since the image is projected, the image is dynamic, and page turning can be easily performed by operating the operation element. Furthermore, since audio data storage means is provided on the film cassette side, it becomes unnecessary to store audio data of different stories in advance on the toy main body side, so the versatility of the toy main body is expanded. become.
Incidentally, the following is known as a projection device that projects a film and outputs a sound. In other words, this projector is a projector that projects an effect image of peace of mind from a film that has been shot and edited on a wall or screen in a living space to capture natural scenery, features, customs with emotion, shrines and temples, art, etc. And an audio device that produces a sound effect of peace of mind in synchronization with the image projected by the projector. However, this projection apparatus does not project each scene of a story, and does not provide a means for storing audio data on the film cassette side.

1. Overall Configuration FIG. 1 shows a picture book type projection toy. This picture book type projection toy 1 includes a toy body 2 and a film cassette 3. The toy main body 2 is provided with a power button (not shown), a reset button 21, an audio button 22, a page feed button 23 and a page return button 24. The toy main body 2 is provided with a cassette mounting portion 25.
Next, an example of how to use the picture book type projection toy 1 will be described. The power button of the toy body 2 is turned on and the film cassette 3 is mounted. When the reset button 21 is pressed, a film 31 described later is sent to the initial position. Next, when the page feed button 23 is pressed once, an image of the next page is projected on a wall, a screen or the like. Subtitles are attached to the screen, so mothers read it to the infant. When the subtitles on the page have been read, the page advance button 23 is pressed once to advance to the next image. In this way, the process proceeds to the last image. During this time, a mark indicating the location of the sound effect is displayed on the image. When the voice button 22 is pressed at this time, a sound effect related to the projected image is output. If it is desired to return the page halfway, the page return button 24 is pressed once. Then, the film 31 is rewound by one page.
Hereinafter, a detailed configuration of the picture book type projection toy 1 will be described.

2. Detailed Configuration (1) Toy Body The toy body 2 is formed in a disc shape. As shown in FIG. 2, the toy body 2 is configured to have a size that can be operated with both hands supported. A power button (not shown), a reset button 21, a voice button 22, a page feed button 23, and a page return button 24 provided on the toy main body 2 are present at positions where they can be supported with both hands.

  The toy main body 2 is provided with a cassette mounting portion 25. The cassette mounting portion 25 is a recess. The cassette mounting portion 25 is provided with a photo sensor 26 in a protruding state. This photosensor 26 is for detecting a mark on a film 31 (see FIG. 4) described later. The photo sensor 26 is configured so that a light emitting element and a light receiving element are disposed opposite to each other in one case, and a passing object (film 31) between detection grooves is detected without contact.

  In addition, the cassette mounting portion 25 is provided with an arch-shaped protrusion 27 (see FIGS. 1 and 3). In order to illuminate the film 31, a light source 28a and a condenser lens 28b as shown in FIG. Further, the toy body 25 is provided with a projection lens 28c as shown in the figure attached to a mirror copper (hood). Among these, the projection lens 28c is configured to be able to focus by rotating the mirror copper. In the figure, reference numeral 28d indicates a stop, and 28e indicates a projected image.

A light emitting diode (LED) is used as the light source 28a. Since the light emitting diode has a small amount of light, two or more LEDs are used here to cover it. Further, as the projection lens 28c, a convex meniscus projection lens having a front stop concave surface that can obtain a wide-angle image with little field curvature is used. The projection lens 28c is an inexpensive single molded plastic aspheric lens. The concave surface of the projection lens 28c is aspheric and is adjusted so that spherical aberration can be corrected. The thickness of the projection lens 28c is adjusted so that coma can be corrected. Furthermore, the convex surface of the projection lens is a spherical surface.
As described above, a bright lens having a large aperture and an F-number is obtained even though it is a single lens, and the light collected by the converging lens 28b due to spherical aberration is poorly collected or the number of light sources is increased by using a plurality of LEDs. Thus, a thick light beam when the light passes through the lens and the aperture position and a diffused light of the light when passing through the film can be taken into the large-aperture lens, and projection with high light efficiency becomes possible.
Incidentally, the optical system shown in FIG. 5B is a general optical system, and one light emitting diode is used as the light source 28a. A spherical lens is used as the projection lens 28c, and a stop 28d is provided on the rear surface side of the projection lens 28c. Even with such a configuration, the object of the present invention can be achieved, but first, there is a problem that the amount of light is small and the image is dark. In addition, the spherical aberration of the projection lens 28c is large. When the aperture 28d is opened, the contrast of the image is reduced by flare. On the other hand, when the aperture 28d is closed, the image is improved but the image becomes dark. Further, there is a problem that the field curvature of the projected image 28e is large and the peripheral image is blurred.

  The toy main body 2 is provided with a battery housing (not shown), a motor M that can rotate forward and backward, and a power transmission mechanism 40 (see FIG. 6A). A battery serving as a power source for the picture book type projection toy 1 is detachably stored in the battery storage unit. On the other hand, the power transmission mechanism 40 is for transmitting motor power to a sprocket 33 described later. According to the power transmission mechanism 40, the motor power is transmitted to the intermittent motion mechanism 42 through the motor shaft and gears 41a to 41f, and the octagonal shaft 43 of the follower 42b of the intermittent motion mechanism 42 (see FIG. 5B). Is transmitted to the sprocket 33. A clutch is preferably provided in the power transmission mechanism 40. This is to prevent the motor M and the components in the power transmission mechanism 40 from being damaged when an overload acts on the shaft 43. In addition, the octagonal shaft 43 and the octagonal hole 33a of the shaft of the sprocket 33 are fitted.

(2) Film Cassette The cassette body 30 of the film cassette 3 is composed of a lower half 30a and an upper half 30b as shown in FIG. In the cassette body 30, a film 31, a guide member 32 that guides the feeding of the film 31, a sprocket 33 that forcibly feeds the film 31, and a shutter member 52 are provided.

  The film 31 is configured as an endless film, and carries 24 frames of images and 2 frames of image blanks. The 24 frames constitute a story as a whole. That is, the images (frame images) of the characteristic scenes of one story are stored in the 24-frame images. Subtitles are attached to each frame image. That is, one frame image corresponds to one page. A bar code B (see FIG. 7) is attached below each frame image. The bar code B is attached to a portion that passes through the detection groove of the photo sensor 26 when the film 31 is fed.

  FIG. 7 shows a state where the film 31 is unfolded. There are two blank image areas on the film 31 at the end. The image blank portions of the two frames are end-to-end and are bonded to each other with a transparent tape. At that time, the transparent tape is adhered over the image blank area of two frames. Numbers 1 to 24 attached to the upper side of the film 31 indicate the projection order of the frame images. That is, the frame images are projected in the order of the numbers 1 to 24 attached on the upper side of the film 31. On the other hand, numerals 1 to 24 (hereinafter referred to as “B1 to B24”) attached to the lower side of the film 31 indicate frames that pass through the detection grooves of the photosensor 26 when projecting the frame images in the projection order. Shows the order.

  Next, the code configuration of the barcode B will be described with reference to FIG. That is, the code configuration of B1 and B24 is configured to be distinguishable from other (B2 to B23) code configurations. The code configurations of B1 and B24 are different from each other. That is, B1 is composed of two narrow bars and B24 is composed of two thick bars. Moreover, the code | cord | chord structure of B2-B13 is comprised from the thick bar and the narrow bar. On the other hand, the code configuration of B14 to B23 includes a narrow bar and a wide bar. That is, the code configuration of B2 to B13 and the code configuration of B14 to B23 are opposite to each other. The bar functions to block light from the light emitting element of the photosensor 26 so that it does not reach the light receiving element.

  The reason why such a code structure is adopted is as follows. That is, the code configuration of B1 is different from the other code configurations in order to stop the film 31 at the initial projection position when the reset button 21 is pressed by detecting the bar code of B1 by the photo sensor 26. It is. The code structure of B24 is different from the other code structures because when the photo sensor 26 detects the bar code of B24 in the process of feeding the film 31, the image blank portion (for two frames) is skipped. This is for stopping at the initial projection position. The reason why the code configurations B2 to B13 and the code configurations B14 to B23 are different from each other is that when the reset button 21 is pressed, the feeding direction of the film 31 is changed and the film 31 is quickly sent to the initial projection position. It is.

  The film 31 is wound around the guide member 32 and is hooked on the sprocket 33. The sprocket 33 meshes with the halation of the film 31, and the film 31 is fed in the forward direction or the reverse direction according to the rotation direction of the motor M and thus the sprocket 33.

  As described above, the guide member 32 has a function of guiding the feeding of the film 31. A recess is formed on the lower side of the guide member 32. An arch-shaped protrusion 27 (described later) is just fitted into the recess through the opening 36 (see FIG. 7) of the lower half 30a.

  As shown in FIG. 8, an opening 51 for receiving the photosensor 26 is provided in the lower half 30a. A shutter member 52 is provided near the opening 51. The shutter member 52 has a structure in which a closing plate 55 is provided on a rotating body 54 having a spiral cam 53 formed on a peripheral surface thereof. The shutter member 52 is urged by a spring (not shown) so that the closing plate 55 is positioned immediately above the opening 51. On the other hand, the film mounting portion 25 is provided with a protruding piece 56 (see FIG. 3). As the film cassette 3 is mounted, the projecting piece 56 enters the slit 57 of the lower half 30a, contacts the cam 53, and rotates the rotating body 54. Accordingly, the rotating body 54 is rotated against the urging force of the spring, and the closing plate 55 is retracted from the position immediately above the opening 51. As a result, the photo sensor 26 enters the film cassette 3 from the opening 51, and the film 31 enters the detection groove.

3. Operation FIG. 9 shows a circuit configuration of the toy main body 2. On the other hand, FIG. 10 shows a control block of the film cassette 3. Hereinafter, the operation will be described.
The control device 60 on the toy body 2 side monitors whether the power switch is turned on and the film cassette 3 is mounted on the film mounting unit 25. The control device 60 monitors whether or not the reset button 21 has been operated after the power switch is turned on and the film cassette 3 has been mounted on the film mounting unit 25. Then, the motor M is temporarily rotated forward (by an amount capable of reading at least one barcode B) temporarily. At this time, since the motor M rotates at a constant speed, the feeding speed of the film 31 is also constant. Therefore, the control device 60 can read the code configuration of each barcode B by monitoring the passing time of the barcode B and the passing time of each bar via the photo sensor 26. Then, the control device 60 controls the rotation direction and the rotation time of the motor M according to whether the reading result is B1, B2 to B13, B14 to B23, B24, or a barcode blank portion (for two frames). Then, the film 31 is sent to the initial position. That is, when the reset button 21 is pressed, it is determined in which direction the film 31 is rotated is faster to send the film 31 to the initial projection position, and the film 31 is initialized at the fastest speed based on the determination. Send to the projection position. If the rotation direction is the same, the film 31 may be rotated in either direction. Next, the control device 60 stops the motor M when the film 31 reaches the initial position. As a result, the initial screen is projected. Although it is not an initial screen, an example of a projection image is shown in FIG.

  Next, the control device 60 monitors whether or not the feed button 62 or 63 has been operated, and rotates the motor M in the direction corresponding to the operated feed button (page feed button 23 or page return button 24). That is, if the page feed button 23 is operated, the motor M is rotated in the forward direction, and if the page return button 24 is operated, the motor M is rotated in the reverse direction.

  Further, the control device 60 monitors whether or not the frame image is projected from the film feed amount from the initial position in consideration of the rotation direction of the motor M, and when the voice button 22 is pressed, The film number corresponding to the frame image is notified to the film cassette 3 side. Thereby, the control device 70 outputs the voice data stored in the memory (storage means) in the control device 70 to the toy main body 2 side. And the main body side control apparatus 60 outputs a sound effect from the speaker S. In this case, the “sound effect” may be an onomatopoeia or onomatopoeia that represents a scene. Examples of onomatopoeia include dog and bird calls, and examples of onomatopoeia include sounds related to frame images such as thunder, water jumping, wind, and river murmur. The film feed amount from the initial position is reset when the film cassette 3 is taken out from the toy main body 2. When the reset button 21 is pressed and the film 31 is sent to the initial projection position, the initial position is set again.

  A substrate 80 on which a control device 70 and other electronic components are mounted is provided at the rear of the film cassette 2. The substrate 80 is provided with a spring 81. A connector (not shown) is provided on the back side of the substrate 80. When the film cassette 3 is mounted on the cassette mounting portion 25, the shutter on the toy main body 2 side is opened, the other connectors are exposed, and are electrically connected to the connectors.
