Furthermore, the shapes of the figure 180 and the traveling body 100 may be similar to a part or the whole of an animal.

Further, although one motor is used, a plurality of motors may be used.
For example, like a car toy, one motor 143 may be used to drive forward, and another motor 143 may be used to change the direction in the left-right direction.
In this case, detection means is inserted into the power supply line to the forward drive motor, and drive control means is provided to stop or drive the direction changing motor, and the main control means 151 is detection means provided in the forward motor circuit. When an overload current detection signal is input from, a control signal for driving the direction changing motor for a predetermined time is output to the drive control means 155.

As another example, the appearance of the traveling toy is assumed to be a shape imitating the appearance of an automobile as shown in FIG.

As another embodiment, as shown in FIG. 7, there is an operation toy composed of a doll 200 and a pedestal portion 230.
The doll 200 has a shape imitating the appearance of an animal, a character, or the like, and includes a main body part 210 that is hollow inside, and an arm part 220 that is pivotally supported by the main body part 210. An operation unit and a motor for driving the arm unit 220 are installed in the cavity of the main body unit 210.
The pedestal portion 230 has a shape simulating the appearance of a via barrel, a wooden box, and the like, and a switch 231 is disposed on the surface thereof, and the inside thereof is a cavity.

  Both arms 220 of the doll 200 are provided with a flag at one end, and the left arm and the right arm have different colors. Further, as shown in FIG. 8, a long shaft hole 221 and a shaft hole 222 are formed at the inner ends of both arms, and the arm 220 is pivotally fixed to the main body 210 through the shaft hole 222. Then, the driving force is transmitted to the arm portion 220 by being connected to the operating portion by the long shaft hole 221.

  The operation unit transmits the rotation of the motor 250 to the arm unit 220 of the doll. As shown in FIG. 8, the worm gear 241 fitted to the motor shaft, the worm wheel 242 meshing with the worm gear 241; The power transmission rod 243 transmits power from the worm wheel 242 to the arm portion 220 and the power transmission rod 243 installed on the opposite side of the power transmission rod 243 with the spur gear 246 interposed therebetween.

The power transmission rod 243 is slidably installed on the inner wall of the main body 210 by a slide projection 247, and a shaft hole is formed in the power transmission rod 243 so as to be connected to the long shaft hole 221 of the doll arm 220. Stopped.

A rack is formed above the power transmission rod 243, and power is transmitted to the power transmission rod 243 installed on the opposite side via the spur gear 246.
Thereby, when the left arm portion rotates upward, the right arm portion rotates downward, and when the left arm portion rotates downward, the right arm portion can rotate upward.

The operation of this embodiment will be described.
When the switch is turned on, the motor 250 rotates, and the worm gear 241 also rotates with this rotation. The worm gear 241 rotates because the external gear of the worm wheel 242 meshes with the worm gear 241. And since the rack 245 carved in the power transmission rod 243 and the internal gear of the worm wheel 242 mesh, the power transmission rod 243 can be moved up and down.

When the left arm portion 220 is rotated upward, the left arm portion 220 is held against the first protrusion 261 installed on the inner wall of the main body portion 210, and a load is applied to the motor 250. At that time, an overload current is generated. The detection means 154 detects the overload current, and the main control means 151 outputs a motor drive signal that instructs the drive control means 155 to reverse the motor 250, and the motor 250 reverses the motor 250 by this motor drive signal. . In this case, a reverse motor drive signal is output when the motor 250 is loaded during normal rotation, and a normal motor drive signal is output when a load is applied during reverse rotation.
As a result, the moving direction of the power transmission rod is reversed, and the left arm portion rotates downward and the right arm portion rotates upward.
When the left arm portion rotates downward, the left arm portion is held against the second protrusion 262 installed on the inner wall of the main body portion 210, and the rotation direction of the arm portion 220 is reversed by the control circuit 150 of the arm portion 220. Pivots upward and the right arm pivots downward.

As a result, the left arm portion 220 is held against the first protrusion 261 and the second protrusion 262 in opposite directions, so that the left arm portion 220 can repeatedly rotate up and down. Repeatedly rotating in the opposite direction to the left arm. Further, when the arm part 220 is moved up and down by the hand of the child, the arm part 220 can be moved up and down within a safe range where no excessive load is applied to the motor. .
Therefore, it is possible to enjoy the movement of the toy by controlling the operation of raising the flags supported by the left and right arm portions 220 in opposite directions by simply turning on the switch without installing a sensor in the stopper portion. .

It consists of the reduction gear train 395 which transmits. In addition, an adjustment gear 396 is provided on the right door 340 so that the left and right doors can move in a double door.

The operation of this embodiment will be described.
When the open switch is turned ON, the motor 391 rotates, and the worm gear 393 also rotates with this rotation. Since the worm gear 393 and the external gear of the worm wheel 394 mesh with each other, the worm wheel 394 rotates.
The reduction gear train 395 transmits the power from the worm wheel 394 to the door portion 340 so that the left and right door portions 340 are synchronized as shown in FIG. It turns to be a double door.

When the left and right door portions 340 are rotated in the opening direction, as shown in FIG. 9, the left and right door portions 340 are abutted against stopper protrusions 370 installed on the outside of the shaft column 352, and the motor is loaded. In this case, an overload current is generated, the overload current is detected by the detection means 154, and the main control means 151 outputs a motor drive signal instructing the drive control means 155 to stop the rotation of the motor. The motor rotation is stopped by the motor drive signal.
Thereby, the door part 340 opens, and when using the mirror part 350, the door part 340 can be stopped at an appropriate open position.

When the close switch is turned on, the left and right doors 340 are rotated in the closing direction by rotating the motor, the left and right doors 340 are held against the frame body 351, and a load is applied to the motor. The rotation of the part 340 stops.
Thereby, the door part 340 can stop the door part 340 in the position which protects a chest.

Moreover, when the pressing force which interrupts rotation is applied to one or both of the left and right door portions 340 from the outside, the rotation of the door portion 340 is stopped by applying a load to the motor.
Thus, when the door 340 is opened and closed by a child, or when a finger is sandwiched between the door 340 and the frame body 351, the door 340 can be safely opened. The rotation can be stopped.

  Therefore, in an operation toy having an automatic opening / closing door, a mechanism for automatically stopping the rotation of the door portion when the door portion rotates is provided with a simple structure without providing a plurality of sensors in the opening / closing portion. An operational toy can be provided.
