- 排紙される用紙の排紙方向に直交する用紙幅方向の中央部より両側が高くなるように形成された用紙積載面を有する昇降可能な排紙台と、
前記用紙積載面上に積載された用紙の最上面の、用紙幅方向の中央部における高さ位置の基準となる位置である基準上面位置に光軸の高さ位置が一致するように配置された発光部および受光部を有し、前記基準上面位置における用紙の有無を、前記発光部が発した光の前記受光部での受光量に基づき検知する検知部と、
前記排紙台へ用紙を排紙する排紙部と、
前記排紙部による排紙動作中において、前記検知部で用紙が検知されるまでは、排紙開始から規定枚数が排紙されるごとに前記排紙台を規定量ずつ下降させ、前記検知部で用紙が検知された後は、用紙が検知されてから規定枚数が排紙されるごとに前記排紙台を規定量ずつ下降させる制御を行う制御部と
を備えることを特徴とする排紙装置。 - 前記制御部は、前記検知部で用紙が検知されないまま、前記排紙台を規定量だけ下降させる動作を規定回数行った場合、排紙動作を中止させることを特徴とする請求項1に記載の排紙装置。
