PURPOSE:To confirm the propriety of extraction control during the process of assembling, by printing on a disk a conductor pattern and a position display symbol pattern for the confirmation of the stop position of an extraction extent control mechanism in one body. CONSTITUTION:On a printed substrate 33, a conductor pattern 51 is formed radially to form conductor parts in number shapes, and they provide a display for the confirmation of the stop position of a ratchet wheel gear 32. Assuming that the part 51a of the conductor pattern 51 is detected with contacts 34 and 35 and a photographic lens moves and stops with a stop ratchet lever 28 engaging with the 1st tooth 47a of a ratchet wheel gear 33, the contact 34 is considered to stop on a number (1) on the printed substrate 33, so that this number (1) is confirmed visually. If the contact 34 is stopping on a number (2), the stop ratchet lever 28 is considered not to engage with the prescribed ratchet tooth 47a of the ratchet wheel gear 33, but to engage with the ratchet tooth 47a, showing malfuction. |
