Title:
Image forming device
Document Type and Number:
Japanese Patent JP6345051
Kind Code:
B2
Abstract:
An image forming apparatus includes an optical detecting device; a movable unit including a rotatable member having a first light-blocking surface and a second light-blocking surface; and a control unit. The movable unit rotates with rotation of the rotatable member so that the second light-blocking surface is movable to a first position where the optical detecting device is light-blocked and a second position where the optical detecting device is not light-blocked, and includes a locking member for locking the second light-blocking surface in the second position. When the first and second light-blocking surfaces pass through a detecting portion of the optical detecting device, the control unit discriminates a state of the movable unit on the basis of a detection result of the optical detecting device.
