15 is a switching lever for switching the position of the gear 13, and the lever 15 is attached to the frame 1 with a shaft 15a.
is supported so that it can swing freely with the fulcrum at one end 1
5b swingably supports one end of the rotating shaft 16 of the gear 13, while the other end 15c abuts the fourth cam 5d, and the gear 13 is configured to mesh with the spur gear 4d at position t5. There is.

The rotary cam body 8 includes an eccentric cam 8a, a plurality of locking grooves 8b around the periphery, and locking members 8c protruding from one side thereof. On the other hand, in order to lock this at random, the above-mentioned operating shaft 14 is provided in the frame 1 at a position facing the locking groove 8b so as to be freely movable in the axial direction, and the same shaft 14 is always held in the above-mentioned position by a return spring 17. 5 cam 5e.

18 is an engagement edge 18 for the eccentric cam 8a.
The setting arm 18 is swingably supported on the frame 1 with a shaft 18b, and the operating arm 19 is swingably attached to the end 18c of the setting arm 18. ing. The actuating arm 19 has an engaging edge 19a that engages with an eccentric cam 20 provided at the end of the rotating shaft 16, and a head body portion 1 to be described later.
A long groove 19b is formed to be engaged with the operating shaft 10a of 0.

The head body 10 has a vertical rotation axis 10b,
The operating shaft 10a is protruded from one end of the rotating shaft 10b, and a return spring 10c for the frame 1 is linked to the other end.

Reference numeral 21 denotes a neck member having a bearing portion 21a that rotatably supports the rotating shaft 10b of the head body portion 10, and the neck member 21 is swingably mounted on a shaft 22 protruding from the frame body 1. Support member 21 for

is installed protrudingly.

A wiring board 22 is provided in the head body part 10, and the lamp 11 is attached to the board 22, and for receiving sound waves at a predetermined level such as impact sound and converting them into output signals such as predetermined electric signals. A sound wave detector 23 is installed. This sonic wave detector 23 uses a ceramic vibrator, and when it is mounted, it is held elastically through a buffer member 24 such as urethane foam. The output end of the sound wave detector 23 is connected to the input side of a drive circuit 25 including an amplifier for starting the motor 2 for a certain period of time based on the output signal thereof. Further, a switching gear 26 is fixed to the operating shaft 14 to constitute a traveling device that advances, stops, and retreats the toy body by utilizing the axial movement of the operating shaft 14, and the gear 26 is attached to the reduction shaft 6. While it is constructed so as to always mesh with the fixed elongated pinion 6a, at the axial movement position p1 of the operating shaft 14, it meshes with the forward gear 31a provided on the shaft provided with the wheel 30, and also at the movement position p.
3, each gear is configured to mesh with the reverse gear 31c via another idle gear 31b.

``Operation'' With the above configuration, the operation will be explained based on the cam configuration diagram corresponding to the rotation angle of the program cam body 5 shown in FIG. 4. The cam contact 9 in contact with the first cam 5a is open at the time of starting. , motor 2 is stopped. Next, when a striking sound of a predetermined level is generated, such as a slap, the sound wave detector 23 receives this sound wave, and based on the output signal, drives the motor 2 for a certain period of time via a drive circuit 25 including an amplifier. When the first cam 5a of the program cam body 5 rotates to a position where the cam contact 9 is closed by the rotation of the motor 2, the cam contact 9 is thereafter kept in the closed state by the first cam 5a. kept, motor 2
Thereafter, the rotation is maintained while the program cam body 5 makes one revolution regardless of the presence or absence of the sound wave signal.

As the program cam body 5 rotates, the cam contact 12 that comes into contact with the second cam 5b allows
The lamp 11 is blinked during ta, the intermediate period tb, and the period tc immediately before stopping, and the third cam 5c is used to control the position t1 immediately after starting, the position t4 immediately before stopping, and the position between these. At t2 and t3, the head and body portions 10 are respectively bowed via the operating pieces 21c. On the other hand, at a position t6 between these positions t1 and t2, the fifth cam 5e causes the operating shaft 1 to
4 is shifted to the forward side position p1, and the switching gear 2
6 meshes with the gear 31a, and the pinion 6 of the reduction shaft 6
The toy body is moved forward for a certain period of time using the driving force generated by a. Similarly, at position t8 between positions t3 and t4, the operating shaft 14 is shifted to the backward position p3 by the fifth cam 5e, the switching gear 26 meshes with the gear 31c via the idle gear 31b, and the pinion of the reduction shaft 6 The toy main body is moved backward for a certain period of time using the driving force generated by 6a.

In this way, by rotating the program cam body 5, a plurality of pre-programmed operations, ie, starting,
A series of operations including some laps, such as blinking lamp - bow - forward - stop - bow - stop - blinking lamp - bow - backward - stop - bow - end, can be sequentially performed.

In the process of such a series of sequential operations, the switching lever 1 is switched by the fifth cam 5d during a predetermined period, that is, at a position t5 around approximately 180 degrees.
Gear 13 meshes with spur gear 4d via gear 5, and driving force is applied to eccentric cam 20. On the other hand, the rotary cam body 8 is connected to the deceleration shaft 6 with a frictional force and is constantly rotated by being given a rotational torque, but at a position t7 just before the driving force is given to the eccentric cam 20, the fifth cam 5e The operating shaft 14 is shifted to the cam locking position p2, and its tip protrudes to the position of the locking member 8c to forcibly lock the rotating cam body 8 against the rotational torque.

This rotary cam body has four locking grooves 8b, and the locking position of the locking groove 8b is selected at random with the locking groove 8b exactly matching the protrusion timing of the operating shaft 14, so that the locking position is selected at random. The operation corresponding to the locking position selected from among the plurality of operations respectively defined at the four locking positions of the stop groove 8b is executed.
That is, the position of the eccentric cam 8a of the rotary cam body 8 restricts the inclination of the setting arm 18 that engages with the eccentric cam 8a from the pivot point, and the position of the pivot point of the operating arm 19 linked to the end portion 18c of the eccentric cam body 8 is controlled. Regulated. Changing the position of the fulcrum of the actuating arm 19 means changing its position relative to the eccentric cam 20 that drives it.
It is set so that a unique movement can be obtained for each of the four positions of the pivot point. For example, as shown in FIG. 5, the locking position of the rotating cam body 8 is
1, the pivot point of the actuating arm 19 is located directly below the eccentric cam 20, and the swinging of the actuating arm 19 by the eccentric cam 20 causes the head body 10 to rotate significantly via the actuating shaft 10a. It can be made to swing. On the other hand, when the rotating cam body 8 is at the locking position s2 as shown in FIG. body part 1
0's swinging motion also becomes smaller. Furthermore, when the rotating cam body 8 is at the locking position s3 as shown in FIG. The head and body portion 10 can be slightly tilted forward together with the operating shaft 10a to perform a nodding motion. Further, when the rotating cam body 8 is at the locking position s4 as shown in FIG. 8, the pivot point of the operating arm 19 approaches the eccentric cam 20, and
The swing angle of No. 9 is relatively shifted to the right side and becomes large, so that the head body portion 10 can be tilted forward greatly together with the operating shaft 10a, and a large nodding motion can be performed.

``Effect of the invention'' The swinging toy according to the invention has a simple mechanical structure and can always make unexpected swinging movements at random from among multiple preset swinging movements without using expensive electronic circuits. The effect is that you can choose. It also has the effect of allowing fortune-telling games to be played using randomly selected head shaking motions.
