When the deceleration motor 55 rotates in one direction, the rotating shaft 44 swings back and forth, and the movement is transmitted through the forearm member 47 through the bell) 50. It is transmitted to the air, and is made to swing up and down.

Note that the support member 43 is attached to the rock, paper, scissors robot body 11.
A covering member (consisting of a mannequin doll) having a shape similar to that of a human body is disposed inside the doll, and a covering member (consisting of a mannequin doll) having a shape similar to that of a human body is disposed on the outside. A covering member serving as a forearm is provided.

In order to detect the rising point and descending point of the forearm member 47, an arm-up sensor 47a and an arm-down sensor 47b are attached as shown in FIG. input to the device. Further, the computer device is connected to a manotosui 56 that is thrown when a person stands on it, and a push button switch (not shown), and furthermore, a prize device 15 (not shown) is connected to the computer device. A sound generating device is connected, and according to commands from the computer device, predetermined prizes are given out and sounds are generated as necessary.

Next, since the operation of the rock-paper-scissors robot is performed by a program of a computer device, its operation will be explained with reference to FIG.

First, when a person steps on the mud switch 56, the rock, paper, scissors robot 10 starts, the deceleration motor 55 forming the arm swing motor starts rotating (step a), and the arm raising sensor 47a moves the forearm member 47, that is, the hand 16. When the ascent is confirmed, activate the sound generator and have the speaker say "Shan" (Stennob B).

Next, the hand 16 is lowered by the rotation of the deceleration motor 55, and the arm lowering sensor 47b is activated (Sten knob C), and when the hand I6 is further raised and the arm lowering sensor 47b senses it, the sound generator utters "Ken". Then repeat the above steps again (stenbu e, f) and say "bon".

Then, the arm lowering sensor 47 detects that the hand 16 has lowered again.
After confirming step b, turn off the deceleration motor 55 (
In step g and h), the computer device determines one of the goochokipa by uttering a random number, drives the air cylinder, and operates the fingers 17 to 21 of the hand 16 to make the goochokipa come out.

In this case, when all the air cylinders are extended, the hand 16 is in a stiff state due to the tension springs 27 to 29. To create a bar state from this upper end, contract all the air cylinders and wire 3
This is done by pulling fingers 6 to 38, and to indicate the condition of the chigoki, extend the middle finger 19, index finger 18, and thumb 17.
, ring finger 20, and little finger 21 are bent. Also, in case of goo, make sure to extend all air cylinders.

Note that in this embodiment, the thumb 17 and other fingers do not collide, but if the thumb 17 and other fingers move at the same time, the fingers collide with each other, and when the thumb 17 bends, the driving cylinder It is also possible to move the fingers faster or slower than the other fingers so that they overlap each other smoothly.

At the same time as this action, the CCD captures the hand movements of the person playing the game.
The camera 12 observes this, and this theory will be explained with reference to FIG.

Figures 7 (A), (B), and (C) show images of a person's hand captured by the CCD camera 12, and the number of shadow parts was counted by scanning with 10 lines. are doing. The results are shown in Tables 1, 2, and 3, respectively.

Table 1 Note that here, the number of memorized fingers is output when the previous number of fingers matches the measured number of fingers, and in the case of N=2 in Table 2, it is measured as 4. to avoid mistakes. Further, in this embodiment, scanning is performed using 10 lines, but the number can be set arbitrarily.

Therefore, in the case of Table 1, the maximum number of memories stored is 2, so it is judged to be poor, in the case of Table 2, the maximum number of memories stored is 1, so it is judged as bad, and in the case of Table 3, Since the maximum number of memories is 4, it is judged to be par.

Here, if the finger position of the person playing the game (opponent) is not in the appropriate position for the CCD camera 12, the above judgment cannot be made, so when scanning 1 to 6, the first finger will be at the predetermined number. After confirming that it is within the number of scans (step j), judgment processing is performed (step k). At this point, if the other party's hand position is incorrect, the position is incorrect, and the voice utterance device utters "More, please, please" (step l), and the finger is returned to the groove (step 1). m), you will have to play rock, paper, scissors all over again from the beginning.

After this, if the rock-paper-scissors robot IO wins, the game ends, and if the opponent wins, the prize device 15 operates to give out a specific prize (step n).

Next, if the rock, paper, scissors robot 10 and the opponent play the same goochokipa, it is "Aiko", so step o) returns the finger to goo, rotates the deceleration motor 55 which is the arm swing motor (stellar pull), When the arm-raising sensor 47a is activated, the user utters "Ai" (
Step q), then the arm-lowering sensor 47b is activated, and the arm-raising sensor 47a is activated again, and the arm-up sensor 47a is activated to say "J".Step r,,s), the arm-lowering sensor 47b is activated again, and the arm-up sensor 47a is activated. to say “sho” (
After step tSu), the steps from stencil g are repeated.

Next, if the same person wants to play the game again, this is done by pressing the push button switch (not shown), and if the person changes, it is detected that the mad switch is turned on again, and the game is played again. become.

Note that the image projected by the CCD camera 12 is
14, so you can check the position of your hands, etc.

〔Effect of the invention〕

As is clear from the above explanation, the rock-paper-scissors robot according to the present invention allows the doll to actually play rock-paper-scissors, so you can actually enjoy the game. Since it can be output, it can be used to drive other devices and play fun games.
