Description

[Detailed Description of the Invention] This invention relates to a response picture book that produces a sound when a predetermined number switch determined according to each page of the picture book is operated.

(Technical background of the invention and its problems) Picture books for young children have been around for a long time, and are indispensable as a means of gaining comprehensive knowledge while arousing interest in things such as names of objects, words, and numbers. It is something. Among these picture books that taught how to count objects, for example, picture books of objects were lined up, and the numbers, or answers, were written on one corner of the page and on another page.

Recent advances in electronic technology, especially semiconductor technology,
As electronic circuits become smaller due to the use of ICs, it will be possible to incorporate these electronic circuits into the picture books mentioned above to make them even more interesting to readers, and the development of such picture books is desired. Ta.

(Purpose of the invention) This invention was made from the above-mentioned circumstances, and its purpose was to apply electronic technology to the conventional picture book for counting the number of objects, and to push the switch with the number written on it to find the correct answer. The idea is to provide a response picture book with a twist, such as a buzzer when the problem arises.

(Summary of the invention) This invention relates to a response picture book, and includes a page detection switch section that detects a page number, a selection switch that can be operated arbitrarily, and a detection switch that detects when predetermined conditions of the page detection switch and the selection switch are met. A correct answer judgment matrix circuit that makes a judgment and outputs a sound signal is provided.

(Example of the invention) Figure 1 shows the structure of a response picture book to which this invention can be applied, with the second page opened. Here, a control circuit, a power source, etc. are housed inside the control section 1, and a quantity selection switch 2 with numbers written on the front panel is arranged. Also, on the side of the bottom of the left page are switch pieces 31A and 32 for detecting the page number.
When A is buried and these pages are closed on the right side, the switch pieces 31B and 32B buried in the corresponding positions, that is, the control part 1
When it comes into contact with the page, it becomes conductive, thereby detecting that the page is closed on the right side.

FIG. 2 shows an embodiment of this invention as a block diagram, in which a page signal P indicating the page number currently opened by the page detection switch section 3 is shown.
1 to PN and the quantity signals S1 to SN selected by the quantity selection switch section 2 are input to the correct answer judgment matrix circuit 4, and if the page signals P1 to PN and the quantity signals S1 to SN have a predetermined relationship, the sound signal of
KK is output and the buzzer 6 is sounded via the buzzer circuit 5.

The configuration will be explained with reference to the circuit diagram of FIG. 3 which embodies this block diagram. First, in the page detection switch unit 3, the switches 31 to 3N, which are in contact when each page is closed to the right, are connected to one end, that is, 31A. ~3NA is the power supply voltage +VB, the other end,
That is, 31B to 3NB are at ground potential through R, and are input to inverters U31 to U3N and AND gates A41 to A4N, and output page signals P1 to PN. On the other hand, in the quantity selection switch section 2, the selected and pressed switch is in the contact state, and these switch sections 31 to
3N has one end set to the power supply potential +VB and the other end set to the ground potential through the resistor R, and is outputted as quantity signals S1 to SN. These output page signals P1~PN and quantity signals S1~
SN is input to the AND gates U41 to U4N of the correct answer judgment matrix circuit 4, and their outputs are input to the OR gate U40, respectively. When these logics are established, the sound signal KK is outputted and sent via the buzzer drive circuit 5. This will cause buzzer 6 to sound.

The operation of this configuration will be explained.

The state of the page in Figure 1 is as follows: switches 31 and 32
Since only one switch is open and the other switches 33 to 3N are all connected, it is impossible to distinguish which page is open in this state. Third
In the figure, the input of inverter U31 is at ground potential because switch 31 is open, so it is at the so-called "L" level.
Therefore, the output of U31 is inverted and becomes "H". Moreover, since the input of inverter U32 is also "L", its output is also "H". Next, since the switch 33 is closed, the input of the inverter U33 is connected to the power supply voltage +VB, so it is "H", and the output of this U33 is inverted and is "L". Therefore, the output of AND gate A31 is "L", the output of A32 is "H", and all outputs after A33 are "L".
Since only page signal P2 was output as "H", it was possible to detect that the second page was opened. On the other hand, regarding the quantity selection switch section 2, if the correct answer on this page is switch 22, then among the quantity signals S1 to SN, only S2 is +
VB potential, that is, "H", is outputted, and the other quantity signals S1 and S3 to SN are outputted as ground potential, that is, "L". Then, the AND gates U41 to 4N of the correct answer judgment matrix circuit 4 are as follows.
Since page signal P2 and quantity signal S2 are input as "H" only in U42, the output of this U42 becomes "H", and the theory of OR gate U40 is established.
Since the sound signal KK is output, the buzzer 6 sounds. At this time, even if the wrong quantity selection switch is pressed, the theory of AND gates U41 and U43 to U4N does not hold, so the buzzer does not sound.

Here, the page detection switch and quantity selection switch have been explained using mechanically operated switches, but they can also be realized using photoelectric switches, magnetic switches, etc., and a buzzer can also be used as a means to generate a sound. However, the same effect can be obtained by using a piezoelectric electronic buzzer or a cassette tape to generate the sound. Furthermore, if the correct answer judgment matrix circuit 4 requires a large number of inputs and a complex matrix, it can be handled by using a pre-programmed memory.

(Effects of the invention) As described above, this invention has an extremely high effect in terms of teaching about numbers, which not only provides visual interest but also the interest of quiz-like hits and misses. We can provide a response picture book.
