A printing apparatus includes: a housing having a discharge port through which a printing medium being allowed to be discharged; an installation part to which a unit being removably installable to the installation part, the unit being configured to surround at least a part of the discharge port in a case the unit is installed, the unit being configured to perform specific processing on the printing medium; and a lid member removably installed to the installation part, the lid member being installable to the installation part in a case the unit is not installed to the installation part.

A printer includes a holder configured to house rolled recording paper, a cover that is attached to the holder to be openable and closable relative to the holder, and a contact part that is attached to the cover and configured to contact the recording paper. The contact part is configured such that the contact part substantially point-contacts the recording paper, and positions on the contact part contacting the recording paper change as the recording paper is unrolled.

A web loader includes a web holder configured to hold a web, a traction member configured to hold the web holder and travel along a loading path of the web, a drive rotation body configured to drive the traction member to travel, and a limiter configured to limit a drive force applied to the drive rotation body.

A printing apparatus includes a printing unit configured to print an image on a sheet; a first exit path from which the sheet with the image printed thereon by the printing unit is discharged while being reversed; a second exit path from which the sheet with the image printed thereon by the printing unit is discharged without being reversed; and a switch member configured to be pivotably arranged so as to switch the first exit path and the second exit path. The first exit path passes above a pivot center of the switch member, and the second exit path passes below the pivot center.

A printing apparatus includes: a printing unit; a first conveyance unit configured to convey a sheet to the printing unit with nipping the sheet; a second conveyance unit provided on a downstream side of the first conveyance unit in a conveyance direction of the sheet, and configured to convey the sheet with nipping the sheet; a third conveyance unit provided on a downstream side of the second conveyance unit in the conveyance direction, and configured to convey the sheet with nipping the sheet; and a switching unit configured to switch a nip state of the second conveyance unit and a released state in which the nip state is released. When the sheet is conveyed by the third conveyance unit, the switching unit switches the nip state and the released state in accordance with a length of the sheet.

A loading device includes a placement portion and a correction portion. The placement portion is provided at a device main body, and a single paper sheet discharged from a discharge unit is placed on the placement portion. The correction portion is disposed downstream of the placement portion in a discharge direction, and corrects curling of the single paper sheet by coming into contact with the single paper sheet moving in the discharge direction from the placement portion. Furthermore, the correction portion includes a contact surface that extends in an intersecting direction intersecting the discharge direction and comes into contact with the single paper sheet, such that the position of the correction portion in the vertical direction becomes lower from upstream to downstream in the discharge direction.

An image forming apparatus, having a housing, a tray detachably attachable to the housing and having a storage to store a sheet-formed medium, an image forming device to form an image on the sheet-formed medium, a conveyer assembly to convey the sheet-formed medium from the storage along a conveyer path, and a cutter to cut the sheet-formed medium at a predetermined position in the conveyer path, is provided. The conveyer assembly includes a feeder roller to feed the sheet-formed medium from the storage to the conveyer path, and an intermediate roller pair arranged in the conveyer path between the feeder roller and the image forming device. The intermediate roller pair is supported by the housing and is configured to nip the sheet-formed medium. The predetermined position is located in the conveyer path between the feeder roller and the intermediate roller pair.

First and second flanges protrude from a shaft portion in a direction crossing an axial direction. The first and second flanges define a position of a roll fitted to the shaft portion in the axial direction. First and second facing surfaces face the roll. First and second contact portions protrude from the first and second facing surfaces in the axial direction. The first and second contact portions are configured to contact a paper tube. A screw member is rotatable relative to the shaft portion, the first flange, and the second flange, thereby changing a relative position of the first flange and the second flange between a hold position at which the first and second contact portions press and hold the paper tube in the axial direction and a separation position at which at least the first contact portion or the second contact portion is separated from the paper tube.

In a printer that performs printing on a label of a continuous paper while feeding the continuous paper unwound from a paper sheet supply unit to a side of a printing head portion via a damper portion, a head pressure plate is arranged between an operating portion that adjusts a pressing force against a thermal head portion and a printing line of the thermal head portion such that the head pressure plate is formed extended to connect them.

An image recording apparatus includes a housing in which a conveyance path is formed, a feed tray insertable into and removable from the housing, configured to accommodate sheet media, and including a first accommodating portion, an image recording portion, a guide member configured to guide one of the sheet media, a stopper movable between a restriction state in which the stopper abuts against a leading end of the sheet medium to prevent the sheet medium from reaching a bank provided and a retraction state in which the stopper is separated from the leading end to allow the sheet medium to reach the guide member, when the feed tray is inserted into the housing, and a flap provided above the sheet media and movable in an up-down direction by pivoting about a given rotation axis.
