发明名称 Medium conveying device and image forming apparatus
摘要 A medium conveying device includes a medium placing tray provided on a main body of an image forming apparatus to be openable and closable. The medium placing tray includes a placing portion on which a medium is placed. The medium conveying device includes a first displacement member including a contact portion that contacts the medium placed on the placing portion and a first engaging portion, and a second displacement member including a second engaging portion that engages the first engaging portion. A detecting unit detects a displacement state of the second displacement member. A determination unit determines the presence or absence of the medium on the placing portion based on a detection result of the detection unit. The first engaging portion and the second engaging portion engage and disengages from each other in conjunction with opening and closing operation of the medium placing tray.
