PURPOSE:To prevent a copying machine from operating even if an input key is inadvertently operated by providing a means for folding the input key. CONSTITUTION:The device displays that the copying machine is ready to operate when a fixing device is warmed up after closing of a power source. However an input key is in a holding state and therefore even if a print key 4 is pushed, the copying machine does not operate. When a key 8 for releasing holding is pushed or an original retaining plate is lifted, the holding is released and the key input is accepted for specified time and therefore copying is started when the print key 4 is pushed during this time. |
