PURPOSE:To make it unnecessary to execute a complicated exposure quantity setting operation with an original has been replaced, by providing a storage means for storing a set exposure quantity, and providing a read-out means for reading out the set exposure quantity. CONSTITUTION:The titled device is constituted so that a copy signal by a print key 6, a manual key 11 signal, a signal of selective keys 12, 13 and 15, and a memory key 15 signal are inputted to a controlling circuit 24, a value of a variable resistor 25 set by an operating knob, and a storage signal of memories 26, 27 and 28 are inputted to the controlling circuit 24, the value of the variable resistor 25 or a signal corresponding to the signal read from the memories 26, 27 and 28 is applied to a lamp circuit 29, and also a display signal is applied selectively to LEDs 17, 18, 19 and 20. Also, the value of the variable resistor 25 is read and written in one of the memories 26, 27 and 28. |
