The striking member 78 is rotated via a gear mechanism 77 connected to the shaft 14, so that the rotation of the shaft 14 causes the bell 76 to ring.

The operation of the addition toy constructed as described above will be described in detail below.

First, when the push button 10a is pressed, the push button 10a comes into contact with the tip of the operating body 28, causing the operating body 28 to rotate clockwise about the shaft 16.

Due to this rotation, the arm rod 34 pivoted to the hanging pieces 32, 32
, 35 forward with a predetermined stroke, and the arm rod 34
The claws 40.41 formed at the tips of the rotating wheels 17.
23. Rotate 27 by - increments.

At the same time, the rotating wheels 17 and 19 also have coiled springs 20 and 20.
It rotates clockwise while accumulating pressure.

When the rotary wheel 17 in the initial position rotates by - increments in this way, the number 1 appears at the opening 6 of the case 1.

Then, when the push button 10a is pressed again, a similar operation is performed and the number 2 appears in the opening 6.

That is, when the push button 10a is pressed, the same number of numbers as the number of times is displayed as the rotary wheel 17 rotates in intermittently.

Further, since the arm rod 35 is reciprocating the same number of times as the arm rod 34, the rotary wheel 19 performs the same number of intermittent rotations as the rotary wheel 17.

Note that the rotary wheel 17.19 rotates intermittently while accumulating pressure in the coiled springs 20, 20, but the pawl of the first ratchet 1-21.26 integrally attached to the rotary wheel 17.19 is connected to the bent arm 57, Since it engages with the pawl 59, the return rotation is regulated.

After pressing the push button 10a and displaying an appropriate number in the opening 6 in this way, the push button 10b is pressed.

Then, the other rotary wheel 18 performs the same operation as the rotary wheel 17, and displays the same number of numbers in the opening 7 as the number of times the push button 10b is pressed.

At this time, the pawls 52.53 formed on the arm rods 46.47 are connected to the respective second ratchets l-24, 27 of the rotary wheels 18.19.
Since the rotary wheel 19 is engaged with the rotary wheel 18, the rotary wheel 19 performs the same number of intermittent rotations as the rotary wheel 18.

Thus, the rotating wheel 19 rotates intermittently by the total number of rotations of the rotating wheels 17 and 18.

The outer peripheral surface of each rotary wheel 17, 18.19 is displayed so that the number appearing in each opening 6, 7.8 increases by 1 each time the rotary wheel rotates in increments. Therefore, when the numbers of the rotating wheels 17 and 18 facing the openings 6 and 7 are both set to 0, the number of the rotating wheel 19 facing the opening 8 is O.
If each rotary wheel is attached to the shaft 14 as shown in FIG.

When 10b is pressed and rotated, the numbers appearing in the openings 6 and 7 are added, and the answer automatically appears in the opening 8.

To summarize the above operation, the rotating wheel 17 displaying the number to be added is rotated in increments via the pawl 40 and the second ratchet 23 the number of times the push button 10a is pressed, and the number of increments is the same as the number of rotations in increments. The rotary wheel 19, which displays the number corresponding to the answer, rotates in increments via the pawl 41 and the second ratchet 27, and in the same way, the rotary wheels 18 and 19 rotate in increments the number of times the push button 10b is pressed. do.

Since the rotary wheel 19 rotates in increments equal to the total number of rotations in increments of the rotary wheels 17 and 18, if numbers are displayed on each of the rotary wheels in the arrangement as described above, the number can be displayed on the windows 6 and 7. The answer obtained by adding up the numbers that appeared will appear in window 8.

Then, as the shaft 14 rotates intermittently, the striking member 78 rotates and strikes the bell 76, producing a sound.

In this way, numbers equal to the number of times the pushbuttons 10a and 10C are pressed are displayed in each opening 6 and 7, and the added number is positioned in the opening 8, and then the pushbutton 1 is pressed.
0C is pressed to rotate the operating body 70, the rotational movement of the operating body 70 is transmitted to the arm lever 69 via the connecting rod 71 connected thereto, and the arm lever 69 is rotated counterclockwise in the figure. The hidden plate 9 is rotated upward by being moved.

This allows you to read the answer numbers.

Next, when the answer is known, the user presses the push button 10d, rotates the operating body 66 clockwise about the shaft 15 and presses it down, thereby moving the horizontal rod 65 downward.

Due to this downward movement of the horizontal rod 65, the bent arms 57, 58, 59 whose rear portions are located below the horizontal rod 65 rotate clockwise about the shaft 15, and the claws 60, 61, 62 and the first ratchet are rotated clockwise about the shaft 15. ) Disengage from 21.22.26.

Further, when the bent arms 57 , 58 , 59 rotate clockwise, the rear lower surface of the bent arms touches the upright portion 36 a of the reinforcing plate 36 .
23. The claws 40, 41 formed at the tips of the arm rods 34, 35 and the second ratchet (23.

It makes a sound and rotates back.

It should be noted that return rotation is possible without releasing the engagement between the second ratchets 23, 24, 27 and the pawls 40, 41, 52, 53 by using a one-way clutch mechanism.

Incidentally, the above has only described one preferred embodiment of the present invention, and for example, the first ratchet and the second ratchet I are not provided separately, but the rotary wheel is rotated intermittently by a single ratchet, and the rotary wheel is rotated intermittently. may be regulated.

It is also conceivable to use a pin wheel instead of a ratchet, but the ratchet is superior in terms of ease of assembly and manufacturability.

As is clear from the above explanation, according to the present invention, a plurality of rotating wheels displaying numbers to be added on the outer circumferential surface and a rotating wheel displaying numbers to be added as the answer on the outer circumferential surface are rotatably supported. A ratchet was attached coaxially to each rotary wheel, and the rotary wheels were rotated intermittently by operating an operating body, and the number that was the result of the addition of the incremental rotations of the rotary wheels displaying the numbers to be added was displayed. Since the information is transmitted to the rotary wheel, it has various features such as reliable addition with a simple structure, fewer failures, and the ability to have children learn arithmetic while having fun.
