Abstract
An image forming device having a detection assembly that detects a detection target. The detection assembly includes an actuator having a shaft rotatable about its axis, an abutment portion extending from the shaft and pivotally movable upon abutment of the detection target, and a detected portion pivotally movable about the axis. A detection board is supported to a stationary base component and includes a detection unit for detecting the detected portion. The shaft has one end portion supported to the base component, and another end portion supported to the detection board. Relative positional relationship between the actuator and the detection unit is maintained by the direct supporting manner of the shaft by the detection board.
Claims19
An image forming device comprising:
- an image forming unit for forming an image on a recording medium;
- a base component;
- a detection assembly that detects a detection target, the detection assembly comprising:
- a shaft defining an axis;
- an abutment portion pivotally movable about the axis upon abutment of the detection target onto the abutment portion;
- a detected portion movable integrally with the abutment portion and pivotable between a detected position and a non-detected position;
- a detection unit that detects the detected portion upon the detected portion being moved to the detected position;
- and
- a detection board fixing the detection unit and supported to the base component, the shaft extending through the detection board, whereby a relative positional relationship between the shaft and the detection board is fixed.
A detector unit comprising:
- an actuator having a shaft;
- and
- a board formed with a hole through which the shaft extends, the board having a detector configured to detect the actuator, the actuator being configured to move between a first position where the detector detects the actuator and a second position where the detector misses detecting the actuator.
