The turning instruction circuit 59 has the switch 45, and outputs a turning instruction signal to the control circuit 53 in accordance with the operation of the switch 45. The movement mode instruction circuit 61 has the switch 47, and controls a movement mode instruction signal, that is, a signal instructing movement in a walking mode or a signal instructing movement in a jump mode in accordance with the operation of the switch 47. Output to the circuit 53. When the control circuit 53 receives the speed instruction signal, the turn instruction signal, and the movement mode instruction signal, it executes control processing of the operation mode of the toy body 3 in accordance with each instruction signal. The control process of the operation mode by the control circuit 53 will be specifically described. The pulse width or the pulse period of the pulse signal supplied to the pair of coils 21a and 21b according to the speed instruction signal from the speed adjustment circuit 57 is controlled. By doing so, the swing speed of the pair of legs 19a and 19b is adjusted.
As a result, the traveling speed of the toy body 3 is adjusted. Further, when the control circuit 53 receives the signal instructing the movement in the walking mode, the phase of the pulse signal supplied to the pair of coils 21a and 21b is changed, so that the pair of legs 19a and 19b are alternately arranged. Rock. When the control circuit 53 receives the signal instructing the movement in the jump mode, it synchronizes the pair of legs 19a and 19b by synchronizing the phases of the pulse signals supplied to the pair of coils 21a and 21b. To rock. Further, when the control circuit 53 receives a turning instruction signal to turn right, the supply of the pulse signal to the leg 19b located on the right side in the traveling direction is interrupted, and only the leg 19a located on the left side in the traveling direction is pulsed. Supply a signal. Then, when the control circuit 53 inputs the turning instruction signal to the effect that the vehicle turns left, the supply of the pulse signal to the leg body 19a located on the left side in the traveling direction is interrupted, and the pulse signal is transmitted only to the leg body 19b located on the right side in the traveling direction. To supply.

Next, the basic operation will be described with reference to FIGS. 4, 6, 7 and 8. When the lever 43 of the control device 7 is properly pulled in, a pulse signal as shown in FIG. 8 is supplied to the pair of coils 21a and 21b. First, the case where the control device 7 outputs the pulse signal a as shown in FIG. 8A to the coil 21a and the pulse signal b as shown in FIG. 8B to the coil 21b will be described. At time t1, when a positive pulse having a pulse width Ta is output to the coil 21a and a negative pulse having a pulse width Ta is output to the coil 21b, the pair of coils 21a, 21b.
At the ends of the magnetic poles, magnetic poles are generated according to the directions of the currents flowing through the magnetic poles. Here, as shown in FIG. 6, the coil 21a
The magnetic pole S is generated at the right end of the coil, that is, the side facing the permanent magnet 15, and the magnetic pole N is generated at the left end of the coil 21b, that is, the side facing the permanent magnet 15. Then, the magnetic pole S of the coil 21a and the magnetic pole S of the permanent magnet 15 repel, and the magnetic pole S of the coil 21a and the permanent magnet 15 repulsive.
And the magnetic pole N of. As a result, the coil 21a moves rearward RL, so that the leg 19a is swung rearward to move the foot portion 23a rearward, as shown in FIG. on the other hand,
The coil 21b has a magnetic pole N on the side facing the permanent magnet 15.
Is generated, the magnetic pole N of the coil 21b and the permanent magnet 1
The magnetic pole S of No. 5 attracts the magnetic pole N of the coil 21b.
And the magnetic pole N of the permanent magnet 15 repels each other. As a result, the coil 21b moves forward FR to swing the leg 19b forward, so that the foot portion 23b moves forward.

Next, at time t3, when a negative pulse having a pulse width Tc is output to the coil 21a and a positive pulse having a pulse width Tc is output to the coil 21b, as shown in FIG. 7, the right end portion of the coil 21a, That is, the magnetic pole N is generated on the side facing the permanent magnet 15, and the magnetic pole S is generated on the left end portion of the coil 21b, that is, the side facing the permanent magnet 15. Then, the magnetic pole N of the coil 21a and the magnetic pole S of the permanent magnet 15 are attracted, and the magnetic pole N of the coil 21a and the permanent magnet 1 are attracted.
The magnetic pole N of 5 repels. As a result, the coil 21a moves forward FL to swing the leg 19a, so that the foot 2
3a moves forward. On the other hand, in the coil 21b, since the magnetic pole S is generated on the side facing the permanent magnet 15, the magnetic pole S of the coil 21b and the magnetic pole S of the permanent magnet 15 repel each other, and the magnetic pole S of the coil 21b and the permanent magnet 15 repel each other. Magnetic pole N
And suck. As a result, the coil 21b moves rearward RR and swings the leg 19b, so that the foot portion 23b moves rearward.

Similarly, the above operation is repeated. Therefore, the pair of legs 19a and 19b alternately swing. That is, the leg body 19a swings backward RL, and at the same time, the leg body 19b swings forward FR.
After that, the leg body 19a swings forward FL, and at the same time, the leg body 19b swings rearward RR. The legs 23a and 23b move alternately according to the swing of the pair of legs 19a and 19b. Here, when each of the foot portions 23a and 23b moves rearward, friction is generated between the foot portions 23a and 23b and the traveling surface. Since the pair of front portions 27a and 27b are provided parallel to the traveling direction F and inclined forward and upward, and the pair of ground portions 25a and 25b are formed of a rubber member having a large friction coefficient. , A pair of ground parts 25a, 2
The friction when 5b moves backward is greater than the friction when it moves forward. Therefore, when the pair of grounding portions 25a and 25b alternately move backward, the toy body 3 moves forward as if walking. That is, the pair of ground portions 2
The toy body 3 can be moved forward due to the difference in friction between the backward movement and the forward movement of the 5a and 25b.

Next, the operation when the lever 43 is further pulled will be described. When the lever 43 is further retracted, the time Tb,
Td becomes shorter, and the pulse period of the pulse signals a and b is set shorter according to the amount of pulling of the lever 43. As a result, the rocking speed of the pair of legs 19a and 19b is increased,
The traveling speed of the toy body 3 can be increased. The pulse widths Ta and Tc shown in FIG.
The value is set to an appropriate value in consideration of the rocking speed of 19b.

Next, the operation when the switch 45 is operated will be described. When the right pressing portion of the switch 45 is pushed in, the supply of the pulse signal to the leg 19b located on the right side in the traveling direction is interrupted, and the pulse signal is supplied only to the leg 19a located on the left side in the traveling direction. As a result, only the leg 19a swings, and the toy body 3 can be turned to the right. When the left pressing portion of the switch 45 is pushed, the supply of the pulse signal to the leg 19a located on the left side in the traveling direction is interrupted, and the pulse signal is supplied only to the leg 19b located on the right side in the traveling direction. As a result, only the leg 19b swings, and the toy body 3 can be turned to the left.

Next, the operation when the switch 47 is operated will be described with reference to FIG. When the switch 47 is pressed, the movement mode instruction circuit 61 outputs a signal instructing movement in a jump mode to the control circuit 53. As a result, the control circuit 53 synchronizes the phases of both the pulse signal a and the pulse signal b supplied to the pair of coils 21a and 21b. That is, the pulse signal a as shown in FIG. 9A is output to the coil 21a, and the pulse signal b as shown in FIG. 9B is output to the coil 21b. The pulse signal a and the pulse signal b have the same pulse waveform, and the pair of legs 19
The a and 19b are rocked in synchronization. Therefore, the pair of ground portions 25a and 25b simultaneously move in the same direction. In this way, when the pair of grounding portions 25a and 25b simultaneously move backward, the toy body 3 can be operated as if it were a "rabbit jump", that is, a rabbit jumps.

Next, another embodiment according to the present invention will be described with reference to FIG. In the embodiment shown in FIG. 10, the output timing of the pulse signal b is shifted by a time corresponding to the pulse width Ta from the output timing of the pulse signal a, so that the running motion of the running toy is interesting. It is characterized by More specifically, the control device used in this embodiment outputs a pulse signal a as shown in FIG. 10 (A) to the coil 21a and a pulse signal b as shown in FIG. 10 (B) to the coil 21b. To do. Therefore, the action of swinging the pair of legs 19a and 19b is as shown in FIG.
Is similar to the embodiment shown in FIG.
When it swings to, the leg 19b swings rearward RR immediately thereafter. Then, when the leg body 19a swings rearward RL again after the time corresponding to the pulse widths Tc and Td elapses, the leg body 19b swings rearward RR immediately thereafter. As a result, the running toy operates for a time corresponding to the pulse widths Ta and Tb, and then stops for a time corresponding to the pulse widths Tc and Td. Since the running motion and the stopping of the motion are repeated in this way, it is possible to add fun to the running motion of the running toy.
