摘要： A medium discharge device includes: a discharge unit that discharges a medium; a first medium receiving tray that receives the medium discharged by the discharge unit; and a second medium receiving tray that is provided above the first medium receiving tray in a vertical direction and receives the medium discharged by the discharge unit. The second medium receiving tray is capable of changing a position between an advance position for receiving a medium, which is discharged, by causing at least an upstream zone of the tray including an upstream side end portion in a medium discharge direction to advance to a passing route of the medium from the discharge unit toward the first medium receiving tray and a retraction position to which the upstream zone retracts from the passing route.

摘要： An upstream-side unit of a reading unit of an automatic document feeder has protruding portions that protrude toward a surface that forms a document feeding path in a mechanism body unit on both sides of a document in the width direction outside a feeding portion that forms the document feeding path. Positioning of the upstream-side unit provided so as to be rotatable with respect to the mechanism body unit is performed by making protruding portions come in contact with a guide surface of the mechanism body unit, the guide surface forming the document feeding path. By adopting this configuration, because the protruding portions provided on both sides of the document in the width direction outside the document feeding path are used to perform positioning, it is possible to increase the accuracy of clearance for allowing a document to pass through the document feeding path.

摘要： A transported material transporting device including: a power transmission switching mechanism configured to switch the transmission of the power between the nip-release switching mechanism and the drive motor between a transmitted state and a blocked state; a detection unit provided in the reversing path and configured to detect the presence or absence of the material to be transported which enters the reversing path; and a blocked-state locking mechanism configured to lock the blocked state of the power transmission switching mechanism when the discharging roller is in the released state, wherein the locked state of the blocked-state locking mechanism is released and the power transmission switching mechanism is switched from the blocked state to the transmitted state upon detection of the position of the trailing end of the material to be transported entering the reversing path by the detection unit.
