Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a picture book for children and the like.

(Prior Art) Conventionally, as disclosed in Japanese Utility Model Publication No. 57-31098, picture books have been equipped with a battery, a power switch, and a plurality of light emitting diodes and melody chips. There were some that blinked and others that played a melody. There was also one in which a light sensor was placed inside the leaf plate, and when the pages were spread, the light sensor was sensitive to light and activated the light emitting diode or melody chip.

(Problem that the invention aims to solve) However, in the conventional picture book using the above-mentioned optical sensor, the optical sensor is sensitive to light the moment the leaf plate is opened, and the light is emitted before the leaf plate has finished opening. It had the disadvantage that operating mechanisms such as diodes and melody chips would operate.

(Means for Solving the Problems) The present invention was made in consideration of the above-mentioned drawbacks of the conventional technology, and includes attaching a shielding body to the leaf plate so as to be able to open and close the light to the optical sensor. This is an attempt to eliminate the above-mentioned conventional drawbacks.

(Function) In the present invention, by opening the shield when the picture book is spread, the operating mechanisms such as the light blinking mechanism and the sound generating mechanism operate.

(Example) Next, the present invention will be explained in detail based on the example shown in FIGS. 1 to 3.

Reference numeral 1 in the figure is a picture book that is made up of a plurality of leaf plates 10 bound together at their ends so that they can be spread open.

The leaf board 10 that serves as the front cover of the picture book 1 is, as shown in FIG. A double-page spread surface is formed by pasting a light-transmitting cover 13 so as to cover the provided storage section 12. In the storage section 12, a thin battery 2, a light blinking mechanism section 3, a sound generating mechanism section 4, a printed circuit board 5, and a light sensor 6 are arranged.

The optical sensor 6 is connected to the base of a transistor 50 provided on the printed circuit board 5, and when the optical sensor 6 senses the light that has passed through the cover 13, the optical sensor 6 is connected to the light blinking mechanism section 3 side or the sound generating mechanism section 4 side. is configured to apply a voltage to.

The light flashing mechanism section 3 includes eight light emitting diodes 30 attached at predetermined positions in the storage section 12 and mounted on a printed circuit board 5 so as to be exposed through a hole a bored in the cover 13. The light-emitting diodes 30 are arranged so as to blink sequentially in sets of two by means of a clock circuit constructed in the element 31. Furthermore, the sound generating mechanism section 4 is composed of a melody chip 40.

In the figure, 7 is a thin plate-like shielding body, and as shown in FIG.
It is attached to the cover 13 using the side edges as hinges so as to be openable and closable so as to cover the light transmitting part b of No. 3. The shielding body 7 has the shape of, for example, the door of a cuckoo clock, corresponding to the pattern on the cover 13, and the pattern of the door is printed on its surface, and the light transmitting part b has a pattern of a cuckoo of the cuckoo clock. is printed on it, and when the shield 7 is opened, the pigeon pattern on the light transmitting part b is exposed, and the optical sensor 6 is sensitive to the light transmitted through the light transmitting part b, and the light blinking mechanism part 3 is activated. At the same time, the sound generating mechanism section 4 operates (for example, the sound of a pigeon telling the time may be played).

(Effects of the invention) As explained above, the present invention combines a battery, an operating mechanism such as a flashing light mechanism or a sound generating mechanism, and a light sensor that operates the operating mechanism in response to light. , a picture book disposed within at least one leaf plate, characterized in that a shielding member for blocking light from reaching the optical sensor is attached to the leaf plate so as to be openable and closable. Therefore, according to the present invention,
Since the shielding body that blocks light from reaching the optical sensor is attached to the leaf plate so that it can be opened and closed, even if the double-page spread formed from the leaf plate on which the optical sensor is arranged is opened, the operating mechanism will not operate. The scene development from the first stage where the two-page spread is opened to the second stage where the shielding plate is opened, the optical sensor is sensitive, and the operating mechanism operates, can be done in one double-page spread, and at different times. The expression effect on double-page spreads is improved. Further, in the case where the operating mechanism is set to operate for a certain period of time, re-operating the operating mechanism requires only repeating opening and closing of the shielding plate, and there is no need to close and reopen the leaf plate. Furthermore, the structure of the shield is simple, and the manufacturing cost of the picture book does not increase, resulting in excellent practical effects.
