PURPOSE:To make unnecessary the execution of the wiring of from a pattern and the removal of the wiring after adjusting and to make small the rapid pattern of the adjusting work by providing the pattern for adjusting the position at the encoder which generates the data showing the position of the driven part of camera accessories. CONSTITUTION:When a light measuring switch 11 is turned on, a CPU36 enters the reading sequence of the data for the lens. The feeding of an electric power source voltage Vcc is started for the lens through a buffer 43. By setting a resetting terminal RES from Low to High, the resetting action of the lens side circuit is executed. After the resetting action is completed, the CPU36 starts to send a clock pulse CP. A three-bit binary counter 37-1 sends one pulse for eight clock pulses to the next step three-bit binary counter 37-2. The three-bit binary counter 37-2 generates successively the signal L1 in accordance with the pulse sent from a three-bit binary counter 37-1, and sends it to an address decoder 37-3.
