Such a motion is given to the toy 31.

That is, in the display mode, when the front light-receiving unit 4 reacts (steps 71 and 72), the toy 31 makes a call and shakes its tail by the rotation of a motor (not shown). If the light receiving unit 4 does not react (steps 71 and 73), the toy 31 does not make a call and its tail does not shake.

In the traveling mode, when the shock sensor 35 reacts (steps 75 and 76), the temporary motor 18 reverses, the toy 31 moves backward with respect to the obstacle, and the shock sensor 35 does not respond. However, if the subsequent light receiving unit 14 responds (steps 77, 78), the motor 18 rotates forward, and the toy 31 takes the predecessor, and the shock sensor 35 and the subsequent light receiving unit 14 respond. If not (steps 77 and 79), the motor 18 rotates in the reverse direction and the toy 31 moves backward.

* Effects The present invention as described above has a simple structure and can distinguish a plurality of picture cards into two. Further, by making the toy utilizing infrared rays into a shape imitating an animal or the like, the infant feels as if the animal toy is operating with its own will, which increases interest. In addition, the infrared light receiving unit compares the infrared light receiving amount with the reference light receiving amount, and the control unit starts / stops or changes the operation of the toy according to the comparison result. Even if some infrared rays are reflected around the card and the light receiving unit detects it, it is possible to prevent malfunction due to that.
