<p>PURPOSE: To recognize double reservation with a simple operation and to surely reserve a desired program. CONSTITUTION: A reservation data input device 3 of a program reservation device 1 is made up of a transparent key matrix 12 in which plural sensing cells 11 of static capacitance type switched on/off by a pressing force provided on a liquid crystal monitor 2c are arranged in a matrix in 2-dimensionally, a longitudinal shift register 13 and a lateral shift register 14 entering X and Y coordinates of the key matrix 12 by a signal from the sensing cells 11, and an arithmetic circuit 15 generating program information based on the X and Y coordinates. The arithmetic circuit, 15 scans the key matrix 12 by shifting bits of the longitudinal shift register 13 and the lateral shift register 14 within a prescribed time thereby obtaining the X and Y coordinates. Then a remote commander 4 is controlled by the generated program information to reserve the program.</p> |
