Each individual display section 21 is arranged corresponding to the individual operation section 22, and is capable of displaying two states corresponding to on and off of the load (blinking, two-color light emission, etc.). The address storage means 15 uses a rewritable memory such as an EEPROM. Further, the address input means 16 consists of a numeric keypad, and the address display means 17 uses a 7-segment liquid crystal display or a light emitting diode display. The map display terminal 10 further includes a mode switching means 18, a pattern operation means 19, and a pattern storage means 20.
