An embodiment of the present invention is a printer in which peeling issuing and continuous issuing can be switched. Peeling issuing allows a label to be issued after being peeled from a liner of a print medium with the label releasably attached on the liner. Continuous issuing allows the label to be issued without being peeled from the liner. The printer includes a feed roller configured to feed the print medium and also includes a peeling unit including a peeling roller holder and a peeling roller cover. The peeling roller holder holds a peeling roller that faces the feed roller in peeling issuing. The peeling roller cover axially supports the peeling roller holder in a swingable manner and is movable between a closed position and an open position. When the peeling roller cover is at the open position, the peeling roller holder is swingable between a first position for facing a back surface of the peeling roller cover and a second position at which the peeling roller is not covered with the peeling roller cover. The peeling unit further includes a biasing member that biases the peeling roller holder from the first position to the second position.

A medium transport portion includes a main body portion, a tray unit, and a support guide member. The main body portion includes a first manual feed path and a second manual feed path. The tray unit can be accommodated in the main body portion in a non-use state, and a medium is mounted thereon in a use state. The support guide member is movable in a Z-direction, and supports the tray unit such that a first position that the tray unit is positioned in the first manual feed path, a second position of being positioned in the second manual feed path, and a third position of being accommodated in the main body portion are switched.

An image forming apparatus includes an ejection port, a stacker, a fan, and a duct. From the ejection port, a sheet is ejected to an ejection space in an ejection direction. The stacker stacks the sheet ejected from the ejection port, and the ejection space is disposed above the stacker. The fan is disposed outside the ejection space to suck air. The duct is connected to the fan. The duct has an exhaust port and a guide. The exhaust port is disposed above the ejection port and downstream from the ejection port in the ejection direction to exhaust the air from the exhaust port toward an upper face of the sheet in the ejection space. The guide connects the fan and the exhaust port to guide the air from the fan to the exhaust port.

An image forming apparatus includes an image forming portion and a sheet feed unit. The sheet feed unit has a pickup roller, a feed roller, and a retard roller. The pickup roller makes contact with a recording medium stored in a sheet feed cassette and feeds out the recording medium. The feed roller conveys the recording medium fed out by the pickup roller. The retard roller is kept in pressed contact with the feed roller to form a nip portion and conveys the recording medium while separating one sheet of it from the rest. The feed roller is covered at least partly from above by a first charge elimination member. The first charge elimination member is grounded.

A sheet transport device includes a sheet feeding tray, a reading device, a sheet feeding path, a discharge tray, a discharge path, a discharge elevation device, and a movable wall. On the sheet feeding tray, a plurality of sheets are placed. The discharge tray is located on a lower side of the sheet feeding tray, and receive the plurality of sheets. The discharge path delivers the sheet to the discharge tray. The discharge elevation device moves the discharge path up and down. The discharge path includes a discharge outlet that moves up and down, in a range between the sheet feeding tray and the discharge tray, following an up and downward movement of the discharge path. The movable wall is provided between the discharge outlet and the sheet feeding tray, and changes a posture according to the up and downward movement of the discharge path and the discharge outlet.

A hose box assembly comprises a housing, a hose reel, and a cover. The cover is rotatable between an operational position and a storage position. In the storage position, the cover inhibits an access to an inside of the housing. In the operational position, the inside of the housing is accessible. The hose box assembly is characterized by a frame is movably mounted to the housing such that a hose guidance device is movable relative to the housing during a movement of the cover between the operational position and the storage position. The frame is coupled to the cover such that when the cover is in the operational position, a hose guide is positioned above an upper edge of the housing such that the hose guide is accessible. In the storage position and in the operational position, the hose reel is positioned in the inside of the housing.
