Further, when the receiving unit 2 subsequently receives the same infrared pattern signal (step 4), a pulse signal corresponding to the infrared pattern received by the receiving unit 2 is input to the pattern comparison / determination means 8 and stored in the storage means 7. If it is the same, the one drive control section 4a set in the first control pattern outputs a drive signal to output the drive signal, and the one drive section 5a, for example, the right motor operating section. 6a is driven, and one drive unit 5a rotates one operation unit 6a, for example, the right wheel, and the toy body 1 turns right (step 5). In this way, it can be confirmed that the first control pattern has been set.

In this state, when the receiving unit 2 stops receiving the infrared pattern (step 4), one drive control section 4a stops the output of the drive signal and one drive section 5a stops the drive, The operation part 6a of the toy body 1 stops its operation.
Stops its operation (step 6).

In this state, when the receiving unit 2 receives the infrared pattern signal from the transmitter again (step 7), the receiving unit 2 outputs a pulse signal to the pattern comparison / determination means 8 of the control unit 3, and this pulse is output. When the pattern comparison determination means 8 determines that the signal is the first control pattern (step 8), the one drive control unit 4a drives the drive signal to the one drive unit 5a, and the one operation unit 6a, for example, the right wheel. Is rotated and the toy body 1 turns right (step 5). Further, when the pattern comparison / determination means 8 determines that the infrared pattern received by the receiving unit 2 is different from the first control pattern and determines that the infrared pattern is not stored in the storage means 7 (step 8), the storage means 7 stores It is stored as the second control pattern (step 9).

Further, in FIG. 5, when the receiving unit 2 subsequently receives the same infrared pattern signal (step 10), a pulse signal corresponding to the infrared pattern received by the receiving unit 2 is input to the pattern comparison / determination means 8. And the second control pattern stored in the storage means 7 is compared and determined, and if they are the same, the other drive unit is driven by the drive signal output from the other drive control unit 4b set as the second pattern. 5b, for example, the electric motor on the left side is driven, and the other driving unit 5b rotates the other operating portion 6b, for example, the left wheel, and the toy body 1 turns left (step 11). In this way, it can be confirmed that the second control pattern has been set.

In this state, when the receiving unit 2 receives the infrared pattern signal from the transmitter again (step 1
3), the receiving unit 2 outputs a pulse signal to the pattern comparison / determination unit 8 of the control unit 3, and when the pattern comparison / determination unit 8 determines that the pulse signal is the first control pattern (step 14), one drive control is performed. The part 4a drives the one drive part 5a with the drive signal, the one operation part 6a, for example, the right wheel is rotated, the toy body 1 turns right (step 5), and this pulse signal is used for the pattern comparison / determination means 8 Is not the first control pattern (step 14) but is judged to be the second control pattern (step 15), the other drive control section 4b inputs the drive signal to the other drive section 5b and the other operation section 6b. For example, the left wheel is rotated and the toy body 1 turns left. (Step 11). Further, if the pattern comparison / determination means 8 determines that the infrared pattern received by the receiving unit 2 is an infrared pattern which is not stored in the storage means 7 unlike the first control pattern and the second control pattern (steps 14 and 15), The storage means 7 stores it as the third control pattern (step 16).

Then, in FIG. 6, when the receiving unit 2 continuously receives the same infrared pattern signal (step 17), a pulse signal corresponding to the infrared pattern received by the receiving unit 2 is input to the pattern comparison / determination means 8. Then, the third control pattern stored in the storage means 7 is compared and determined, and if they are the same, both drive control units 4a and 4b set as the third control pattern output both drive signals. Drives 5a, 5b, eg both motor operating parts 6a, 6
b, and both drive units 5a and 5b drive both operating parts 6
By rotating the wheels a, 6b, for example, the wheels on both sides, the toy body 1 goes straight (step 18). In this way, it can be confirmed that the third control pattern has been set.

In this state, when the receiving unit 2 stops receiving the infrared pattern (step 17), both drive control units 4a and 4b stop outputting the drive signal and both drive units 5a and 5b.
The driving of a and 5b is stopped, both of the operation units 6a and 6b are stopped, and the toy body 1 is stopped (step 19).

For example, the left wheel is rotated and the toy body 1 turns left. (Step 24). Further, when the pattern comparison and determination means 8 determines that the infrared pattern received by the receiving unit 2 is an infrared pattern which is not stored in the storage means 7 unlike the first control pattern and the second control pattern (steps 21 and 23), If it is the third control pattern (step 25), both drive control units 4a and 4b output drive signals to both drive units 5b, and both operating units 6a. ， 6b,

If switch 10 is turned on again within a second (step
32), the learning mode is set (step 33), and the control pattern corresponding to the infrared pulse is stored.

If the switch 10 is not turned on again within a predetermined time after the switch 10 is turned on (step 30) and the standby state is released (step 31), it is stored in the storage means 7. The toy body 1 is controlled according to the control pattern (step 34). When the receiving unit 2 does not receive the infrared pattern signal for a predetermined time, for example, 3 minutes or more (step 35), the toy body 1 stops operating and enters the standby state (step 36).
