Abstract
PURPOSE: To remove the restrictions of a use place on a device by providing a two- dimensional information setting space, determined according to reflectivity of light, and a light emitting element and a reflective photosensor which correspond to it on a mask sheet.
CONSTITUTION: A mask sheet 1 is provided with a hollowed part at a position which corresponds to an operation switch SW2, and the sheet 1 is positioned by the hollowed part and SW2. A pulse signal from a pulse generator 11 is frequency- divided by an FF12 and supplied to an infrared rays emitting diode 14. In the state of two-dimensional information 1 that a hole in a panel 3 is covered with a mask sheet 26, pulsive light is reflected and the reflected light is inputted to a phototransistor 15. This signal is amplified and passed through FFs 22 and 23 and a gate 24 to obtain a signal (g), which is held at a level H from the point in time when the pulse is detected. In the state of two-dimensional information 0 that the mask sheet is perforated, the signal (g) is at a level H. A counter 25 counts a pulse signal (h) while the signal (g) is at the level H and, when the count value goes to a prescribed value, outputs a signal (i) to detect the two-dimensional information set in a two-dimensional information space.
