摘要：
An opening and closing device includes a cover gear, a driving source, a cover, a biasing element, and a control portion. The cover gear is rotatably supported in both forward and backward directions. The driving source selectively provides rotation to the cover gear in both the forward and backward directions. The cover is rotatably supported to allow motion in both the forward and backward directions between first and second positions. The biasing element transmits the rotation of the cover gear to the cover while biasing the cover in a predetermined direction from the first position to the second position. The control portion stops the rotation of the driving source, in a case in which the driving source is rotated to move the cover in the predetermined direction, when the cover gear rotates in the predetermined direction by a predetermined angle after the cover has reached the second position.
