 BEST MODE FOR CARRYING OUT THE INVENTION

[0010] 1. Overall configuration

 Figure 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 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 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. Turn on the power button of the toy body 2 and attach the film cassette 3. When reset button 21 is pressed, film 31, which will be described later, is sent to the initial position. Next, when the page feed button 23 is pressed once, the image of the next page is projected on the wall or screen. Subtitles are attached to the screen so that mothers can read and listen to them. When you have finished reading the subtitles on that page, press page feed button 23 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 audio button 22 is pressed at this time, a sound effect related to the projected image is output. If you want to return the page halfway, press the page return button 24 once. Then, film 31 is rewound by one page.

 Hereinafter, a detailed configuration of the picture book type projection toy 1 will be described.

[0011] 2. Detailed configuration

 (1) Toy body

The toy body 2 has a disk shape. As shown in FIG. 2, the toy body 2 is configured to be sized to be supported with both hands. A power button (not shown), a reset button 21, an audio button 22, a page feed button 23, and a page return button 24 provided on the toy body 2 are present at positions where they can be supported with both hands. The toy 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 photo sensor 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 arranged opposite to each other in one case, and a passing object (film 31) between detection grooves is detected in a non-contact manner.

 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). Of these, the projection lens 28c is configured so that it can be focused by rotating the mirror copper. In the figure, reference numeral 28d indicates an aperture, and 28e indicates a projected image.

 [0014] A light emitting diode (LED) is used as the light source 28a. Since light-emitting diodes have low light intensity, two or more LEDs are used here to cover them. Further, as the projection lens 28c, a convex meniscus projection lens is used in which the concave surface of the front aperture that allows a wide-angle image with little curvature of field is forward. This 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 a result, a bright lens with a large aperture and F-number is obtained even though it is a single lens, and the light collected by the condensing lens 28b due to the spherical aberration is poor, and the number of light sources is increased by using multiple LEDs. As a result, a thick luminous flux 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. 5 (B) 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 in such a configuration, the present invention However, first, there is a problem that the image is dark with a small amount of light. Further, when the aperture 28d having a large spherical aberration in the projection lens 28c 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. In addition, there is a problem that a peripheral image with a large field curvature of the projected image 28e is blurred.

 [0015] 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 this 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 further, the octagonal shaft 43 of the follower 42b of the intermittent motion mechanism 42 (FIG. (B) (See below) 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 parts in the power transmission mechanism 40 from being damaged when an overload is applied to the shaft 43. The octagonal shaft 43 and the octagonal hole 33a of the shaft of the sprocket 33 are fitted together.

 [0016] (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 for guiding the feeding of the film 31, a sprocket 33 for forcibly feeding the film 31, and a shirter member 52 are provided.

 [0017] The film 31 is configured as an endless film, and carries 24 frames of images and 2 frames of image blanks. The 24-frame images together make up a story. In other words, each of the 24-frame images contains images of scenes that are characteristic of one story (frame images). Subtitles are attached to each frame image. That is, one frame image corresponds to one page. Barcode B (see Fig. 7) is attached below each frame image. This bar code B is attached to the 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. Two frames of this film 31 There is one blank area at the edge. And the blank area of these two frames Are joined together and bonded together with a transparent tape. At that time, the transparent tape sticks over the blank area of the two frames. The 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 to the upper side of the film 31. On the other hand, the numbers 1 to 24 (hereinafter referred to as “B1 to B24”) attached to the lower side of the film 31 indicate the frames passing through the detection groove 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 configurations of B1 and B24 are configured to be distinguishable from other code configurations (B2 to B23). B1 and B24 have different code configurations. That is, B1 is composed of two narrow bars, and B24 is composed of two wide bars. In addition, the code configuration of B2 to: B13 is composed of a thick bar and a narrow bar. On the other hand, the code structure of B14 ~: B23 consists of narrow bars and thick bars. That is, the code configuration of B2 to: B13 and the code configuration of B14 to: B23 are opposite to each other. Note that the nozzle functions without blocking the light from the light emitting element of the photo sensor 26 to reach the light receiving element.

 [0020] The reason why such a code configuration is adopted is as follows. In other words, the code structure of B1 was made different from the other code structures in order to stop the film 31 at the initial projection position when the reset button 21 was pressed by detecting the bar code of B1 by the photo sensor 26. It is. The code structure of B24 was made different from the other code structures because when the photo sensor 26 detected the B24 bar code in the process of progressively feeding film 31, the blank image area (2 frames) was skipped. Is stopped at the initial projection position. The code configuration of B2 to B13 and the code configuration of B14 to B23 were made different from each other because the film 31 was quickly moved to the initial projection position by changing the feeding direction of the film 31 when the reset button 21 was pressed. It is for sending.

The film 31 is wound around the guide member 32 and is also hooked on the sprocket 33. The sprocket 33 meshes with the harmonics of the film 31, and the film 31 is fed in the forward direction or the reverse direction depending on the rotation direction of the motor M and thus the sprocket 33. The guide member 32 has a function of guiding the feeding of the film 31 as described above. A concave portion 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 shirter member 52 is provided near the opening 51. The shirter 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 the peripheral surface thereof. The shirter 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 in the lower half 30a, contacts the cam 53, and rotates the rotating body 54. As a result, the rotating body 54 is rotated against the urging force of the spring, and the closing plate 55 is also retracted from the position force just 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.

 [0024] 3. Operation

 FIG. 9 shows the circuit configuration of the toy 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 portion 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 installed in the film loading section 25. When the reset button 21 is operated, the motor driver 61 The motor M is temporarily rotated forward (by an amount that can read 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 force B24, or the bar code blank part (for two frames). Then, film 31 is sent to the initial position. That is, the reset button 21 is pressed. When it is determined, it is determined in which direction the film 31 is rotated faster to send the film 31 to the initial projection position, and based on the determination, the film 31 is sent to the initial projection position at the fastest speed. If the direction of rotation 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. An example of the projected image, not the initial screen, is shown in Figure 11! /

[0025] Next, the control device 60 monitors whether or not the feed button 62 or 63 is operated, and rotates the motor M in the direction corresponding to the operated feed button (page feed button 23 or page return button 24). Let 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.

 [0026] The control device 60 monitors the rotation direction of the motor M and monitors how many frames are projected from the film feed amount of the initial position force, and the voice button 22 is pressed. When this happens, the film cassette 3 side is notified of the frame number corresponding to the frame image. As a result, the control device 70 outputs the audio data stored in the memory (storage means) in the control device 70 to the toy main body 2 side. Then, the main body side control device 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 sounds of dogs and birds, 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 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.

 [0027] At the rear of the film cassette 2, a substrate 80 on which a control device 70 and other electronic components are mounted is provided. 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 shirt on the toy body 2 side is opened and the other connectors are exposed, and are electrically connected to the connectors.

[0028] Although the embodiments of the present invention have been described above, the present invention is not limited to the powerful embodiments. Needless to say, various modifications can be made without departing from the scope of the invention.

 Industrial applicability

 [0029] It is possible to realize a picture book type projection toy that is easy to operate and enjoys a dynamic image, and can be used in the field of toys.
