A print unit is disposed in an apparatus having a printing function. The print unit includes a print engine configured to perform printing on a continuous sheet, and a damper located on an upstream side of a sheet entrance of the print engine in a sheet traveling direction and configured to adjust tension applied to the continuous sheet to be fed to the print engine. The damper includes a sheet guide having a planar guide portion which guides the continuous sheet to the sheet entrance, and an end portion of the guide portion on a downstream side in a sheet traveling direction is configured as a fixed end resting on the sheet entrance, and another end portion thereof on an opposite side is configured as a swinging end which is elastically biased toward the continuous sheet by a spring force of a spring.

A receipt printer comprises a discharge port configured to discharge a receipt; a conveyance section configured to convey a paper; a clamping section configured to clamp the paper in the front of the discharge port; and a controller configured to control the conveyance section to discharge the paper from the discharge port. The clamping section includes a fixed section and a movable section forming a paper insertion section, and the paper is clamped by the fixed section and the movable section if the paper is inserted into the paper insertion section. A paper conveyance direction in which the paper is directed to the paper insertion section is different from a paper discharge direction in which the paper is discharged from the discharge port. The controller controls the clamping section such that a front end of the paper is clamped with the clamping section by conveying the paper towards the paper insertion section and the paper is bent into a loop shape by further conveying the paper towards the paper insertion section from a state in which the paper is clamped by the clamping section to be discharged from the discharge port.

A magnetic ink reader includes a conveyance mechanism for a sheet, a magnetizing mechanism configured to magnetize magnetic ink on the sheet and including a magnet having a first side of a first magnetic polarity, that is arranged to face a first surface of the sheet, and a yoke that is formed of a soft magnetic material and includes a base portion attached directly to a second side of the magnet, and an extension portion extending from the base portion such that an end surface of the extension portion faces a second surface of the sheet, and a magnetic detection head along the conveyance path and configured to detect magnetism of the magnetized magnetic ink on the sheet. A first distance between the conveyance path and the first side of the magnet is less than a second distance between the conveyance path and the end surface of the yoke.

According to one embodiment, a magnetic ink reading apparatus includes a transport mechanism, a magnetizing mechanism, a magnetic detection head, a pressing pad, and a friction pad. The transport mechanism transports, along a transport path, a sheet type medium subjected to printing by using magnetic ink. The magnetizing mechanism magnetizes the magnetic ink of the medium on the transport path. The magnetic detection head is arranged along the transport path and reads magnetism of the magnetized magnetic ink. The pressing pad is arranged at a certain distance from one side end portion of the transport path in a width direction, facing the magnetic detection head with the transport path interposed therebetween, and presses the medium transported along the transport path against the magnetic detection head. The friction pad is arranged at a certain distance from the side end portion of the transport path, facing the transport path, and is spaced apart from the pressing pad in a width direction of the medium.
