PURPOSE:To make a device easy to insert and inexpensive, by inputting plural picture information optically to a display part and displaying plural pictures successively to make animation possible. CONSTITUTION:A certain quantity of a card 7, where one-frame components of picture are written, is fed in a picture information input part 4 by rotating a roller 8 with a motor 12, and the light from a light emitting part 10 of a photocoupler 9 is radiated toward the card 7 while moving the photocoupler 9 from one end to the other of the fed card 7 by a motor 13, and the light reflected by the surface of the card 7 is received by a light receiving part 11 to detect the variable density at each point on the card 7, and this variable density is converted to a level change of the electric signal. The output of a received light signal amplifier 20 is stored as picture signal information in an RAM18 through a CPU17. This operation is repeated for cards, where pictures different in every frame are written, to store all picture information of every frame in the RAM18. When a keyboard part 16 is operated, contents in the RAM18 are displayed successively on a display 14. |
