Abstract
An image forming device having a frame, a door, and a movable image forming unit to be assembled in the frame when the door is open. The image forming unit has a support shaft, and frame has a hole on which the support shaft abuts for positioning of the image forming unit relative to the frame when the door is closed. A lock unit formed with a recessed portion is movable in association with the movement of the door. When the door is open, the lock unit is at its abutment position so that the support shaft abuts the recessed portion. When the door is closed the lock unit is moved so that the support shaft is brought into abutment with the hole.

An image forming device comprising:
- a frame having a first positioning part;
- an image forming unit detachably supported to the frame and having a second positioning part abuttable on the first positioning part for positioning the image forming unit relative to the frame;
- a door movable between an open position and a closed position relative to the frame, the image forming unit being detachable from or attachable to the frame at the open position;
- and,
- a restraining portion displaceable in interlocking relation to the movement of the door to a restraining position in response to the movement to the open position to provide abutment of the second positioning part on the restraining portion to inhibit direct abutment between the first positioning part and the second positioning part, and to a non-restraining position in response to the movement to the closed position to provide direct abutment between the first positioning part and the second positioning part.
