PURPOSE:To prevent the erasure of receiving data, by providing a control means for releasing an interruption processing state when a ROM cartridge is mounted to re-open recording operation from a recording stop position. CONSTITUTION:When a ROM cartridge 6 is pulled out, the input at the interruption terminal INT of CPU2 changes to a low level and CPU2 transfers to an interruption processing state to necessarily stop recording operation. At this time, a resistor 14 and a condenser 15 constitute an integrating circuit and chattering generated when the cartridge 6 is pulled out and inserted is prevented. Thereafter, when the ROM cartridge 6 is mounted, the interruption processing state is released and recording is again re-opened from a recording stop position. If recording is finished, the whole of recording operation is finished. |
