A recording device includes a recording unit, a discharge roller unit, a medium receiving tray, a motor serving as a power source of the discharge roller, a power transmission unit that is configured to switch between a power transmission state in which power of the motor is transmitted from the motor to the medium receiving tray, and a power non-transmission state in which the power of the motor is not transmitted from the motor to the medium receiving tray, and a restriction unit that is configured to switch between a restriction state in which the restriction unit restricts displacement of the medium receiving tray when the power transmission unit is in the power non-transmission state, and a non-restriction state in which the restriction unit does not restrict the displacement of the medium receiving tray when the power transmission unit is in the power transmission state.

A printing device includes a sheet placement plate, an ejection roller module and an ejection control module. The ejection roller module is located near the sheet placement plate to eject at least one paper sheet. The ejection control module is connected with the ejection roller module. The ejection roller module is selectively in a released state or an ejection state under control of the ejection control module. When the ejection roller module is in the released state, the at least one paper sheet is transferred to the sheet placement plate through the ejection roller module. The ejection roller module is in the ejection state, the at least one paper sheet is outputted by the ejection roller module.

An adhesive dispenser is disclosed. The adhesive dispenser includes a cartridge, a dispensing roll, a plunger assembly, and a handle. The cartridge defines a cavity. The dispensing roll is positioned within the cavity and adapted to dispense an adhesive tape. The plunger assembly is positioned within the cavity and is adapted to move relative to the cartridge. The handle is adapted to receive the cartridge therein and is adapted to move the plunger assembly relative to the cartridge such that the plunger assembly applies a section of the adhesive tape to a surface adjoining a bottom portion of the cartridge.

A sheet feeding apparatus includes a supporting portion, a regulating unit supported to be movable in a first direction, a feed unit, a variable resistor including a rotary member configured to be rotated by a movement of the regulating unit in the first direction, and having a resistance value changing according to a rotational phase of the rotary member, an interlocking portion configured to rotate the rotary member in conjunction with the regulating unit, and a substrate including a pattern surface to which the variable resistor is connected. An axial center line of the rotary member extends in a second direction orthogonal to the first direction and a direction of gravitational force. The substrate is disposed such that the pattern surface extends in parallel with the first direction and the direction of gravitational force.

A perforation device includes a shaft, a perforation motor, a first perforation unit, a second perforation unit, a first cam, a second cam, a control unit and a perforation switching mechanism. The perforation switching mechanism reciprocates the shaft in an axial direction to selectively arrange the shaft in a first position in which the first cam is opposite the first perforation unit and the second perforation unit and in a second position in which the second cam is opposite the first perforation unit. The perforation switching mechanism includes a rack gear that is attached to the shaft, a perforation switching motor and a pinion gear that is fixed to the rotating shaft of the perforation switching motor and engages with the rack gear. The control unit can selectively perform first perforation processing and second perforation processing by arranging the shaft in the first position and in the second position.

An example finisher includes a first portion extending in a vertical direction, a second portion including an entrance to receive paper as a finishing process target, and a finishing unit to perform a finishing process, the second portion extending from the first portion in a lateral direction, a stacker to receive paper discharged from the finishing unit and which extends in an opposite direction to the second portion based on the first portion, and an elevation driving unit provided on the first portion to elevate the stacker in a vertical direction.

A recording device as a processing device includes: a recording unit accommodated in a housing and configured to perform recording on a medium; and a medium accommodating unit that accommodates the medium discharged from the housing. The medium accommodating unit includes: a sheet-shaped accommodating member; a rotating shaft provided inside the housing and to which one end of the accommodating member is connected; and an operating portion provided separably from the housing and to which the other end of the accommodating member is connected. The accommodating member is wound around the rotating shaft and accommodated inside the housing when the operating portion is mounted on the housing. The accommodating member is fed from the rotating shaft so that the medium is accommodated when the operating portion is separated from the housing.

In one example, a tray to hold sheet media for printing includes: a movable support to support a downstream part of a stack of media sheets in the tray; a barrier near a downstream end of the support, the barrier movable between a closed position in which, when a stack of media sheets is on the support, the barrier blocks a downstream end of the stack and an open position in which, when a stack of media sheets is on the support, the barrier does not block a downstream end of at least part of the stack; and an actuator configured to move the barrier from the closed position to the open position.

A transport device unwinds a medium from a roll body to which a shaft member is mounted and transports the medium. The transport device includes an accommodation portion configured to accommodate the roll body, a main body portion to which the accommodation portion is mounted, and a roller pair configured to nip the medium. The accommodation portion and the main body portion are relatively movable. The main body portion includes a rack configured to engage with a gear of the shaft member. The rack is engaged with the gear when the accommodation portion moves relative to the main body portion to be pulled out of the main body portion.

A feed device includes: a feed tray configured to accommodate a roll, in which a medium is rolled in a roll shape, rotatably; a housing configured to support the feed tray installable; and a pull-back mechanism configured to pull back the medium unrolled from the roll in a direction orthogonal to a rotation axis of the roll in conjunction with an outward movement of the feed tray from the housing in the direction orthogonal to the rotation axis of the roll.
