PURPOSE:To reduce the number of parts to reduce the cost by performing register, clear, stop, and reset operations in the copying operation with one key. CONSTITUTION:The signal inputted by a copy key 2 is inputted to a sequence controller 3 through a resistance R, and required control is performed to drive a load 4. A LED is used to see the operation state of the copy key 2. That is, counting, copy start, or stop is decided to operate a copying machine by the control based on the input time of the key as shown by a timing chart of read of the sequence controller 3 due to turning-on/off time of the copy key 2. |
