Abstract
A photo-interruptor unit includes a photo-interruptor and a supporting portion to detachably support the photo-interruptor. The supporting portion includes a hole which is formed on an attaching surface and through which a hook portion is inserted, and a guide portion to protrude from the attaching surface and guide the hook portion so that it deforms in a deformation direction when the photo-interruptor is moved in a movement direction intersecting an insertion direction. A regulating portion protrudes from the attaching surface and forms continuously with the guide portion to regulate a position in the movement direction of the photo-interruptor. The guide portion includes a first rib portion and a second rib portion that oppose one another in the deformation direction, and a distance between the first rib portion and the second rib portion in the deformation direction narrows toward a downstream direction of the movement direction.
