Abstract
PURPOSE: To detect a movement limit position, prescribed by an optical read method, through the output of a photo detector by providing an unpenetrated and unreflecting part on the light passage of a read beam.
CONSTITUTION: Along the reverse surface of sheet-shaped or plate-shaped information recording medium 21 where inputted information is displayed with eye confirmation by parts easy and hard to pass the read beam through, optical read method 20 is provided and the read beam is caused to strike medium 22 freely moving in a fixed direction and then detected. Then, reflecting surface 23 reflecting the read beam is provided to the top surface of medium 22 and inputted information reflected by the surface 23 is seen through half mirror 24 from the side opposite to read method 20. In the information input device, unpenetrated and unreflecting part 19 is provided on the light passage of read beam 26 at a fixed movement limit position prescribed by read method 20 and the movement limit position is detected via the output of the photodetector.
