Abstract: A path switcher is provided at a point where a transport path along which a medium is to be transported branches out into a first branch path and a second branch path that are to be switched between by the path switcher. The path switcher includes: a switching component including a first arm and a second arm, the first arm being swingable at the point of branching of the transport path, the second arm being connected to a distal end of the first arm with an aid of a motion-allowing part, the switching component being configured to close one of the first branch path and the second branch path while opening an other of the first branch path and the second branch path; an elastic retaining component provided around the motion-allowing part and configured to elastically retain the first arm and the second arm in a predetermined positional relationship; and a rotary component rotatably provided at a distal end of the second arm and that is to come into contact with the medium.

Abstract: A sheet transport device includes: a curved transport path for a sheet; and multiple endless belt pairs arranged along the transport path and having transport surfaces that are in contact with each other.

Abstract: A medium transport device includes a guide configured to guide a medium on which an image is recorded, and curved along a transport direction of the medium, and an actuator configured to actuate the guide between a contact position where the guide is in contact with the medium and a separation position where the guide is separated from the medium. The guide is configured to move to the contact position until a leading edge of the medium in the transport direction passes along the guide, and move to the separation position after the leading edge of the medium in the transport direction has passed along the guide.

Abstract: A sheet transport device includes: a curved sheet transport path; multiple transport roller pairs disposed in the sheet transport path; multiple driving sources that drive the multiple transport roller pairs; multiple load detectors that detect the loads of the multiple driving sources; and a control unit that controls the driving speed of at least one of the driving sources such that detection results obtained by the load detectors are within a predetermined range in accordance with the position of the leading end of a sheet.

Abstract: A sheet transport device includes: a first transport roller that transports a sheet and that has two first nip parts, which are spaced apart in a sheet width direction and nip portions of the sheet; a second transport roller that transports the sheet, that is disposed upstream of the first transport roller in a sheet transport direction, that has a second nip part, which nips a portion of the sheet at a position different from at least one of the first nip parts in the width direction, and that stops exerting a force that transports the sheet when the sheet has been transferred to the first transport roller; and two tension-applying parts that are provided on the first transport roller, on the outer side of the two first nip parts in the width direction, and that apply, to the sheet, tension pulling the sheet outward in the width direction.

Abstract: An image forming apparatus includes a sheet accommodating portion that is attachable to and removable from an apparatus body and that is capable of accommodating a sheet therein; a detecting part that detects the presence/absence of a sheet in the sheet accommodating portion; a fixing part that fixes the status of detection by the detecting part to a sheet absent state when the sheet accommodating portion is not attached to the apparatus body; an informing part that informs a user of the status of the apparatus; and a control part that causes the informing part to inform the user of the possibility of a sheet left in the apparatus when the status of detection by the detecting part changes from a sheet present state to the sheet absent state during standby when printing is not performed.
