and outputs a sound of 34 kuh 34 a groan of a dog from the speaker 50 through the amplifier circuit 49 step l11 with the light emitting flag register f1 set to 34 1 34 by operation of the start key 42c and infrared light being emitted from the light emitting element 44d of the transferring unit 44 and further with the light receiving register l reset to 34 0 34 when the user waves his hand once to display image data of a disheartened dog stored in the rom 43 the light receiving element 45b of the receiving unit 45 receives infrared light reflected on the user 39 s hand then the timer 41a starts the time counting operation and time counting data is written in the time register 46c whereby the time counting process starts counting a predetermined time duration for example 2 seconds steps k4 k12 k13 and the number of receiving time register l is incremented by 1 and is set to 34 1 34 step k14 during the time counting operation of the time register 46c before the time counting data to be written in the time register 46c exceeds a predetermined time duration image data of a dog coming out from the doghouse corresponding to the rom address 34 m 0 34 are repeatedly displayed and pertinent effect sound data are audibly output steps ks k15 kc l1 l2 l3 when the time counting data to be written in the time register 46c exceeds the predetermined time duration the timer 41a stops time counting operation and the time register 46c is cleared steps k15 k16 since the image display mode flag register t is set to 34 0 34.
