A supply device for a roll medium includes a drawer-type lower holding unit configured to support a shaft of a roll medium to hold the roll medium, and a guide member configured to be pressed in a direction toward the shaft from below to come into contact with the roll medium held by the lower holding unit, and be displaced in accordance with a change in an outer diameter of the roll medium. In addition, the lower holding unit is configured to be drawn from a main body of the supply device in a first direction. When the lower holding unit, in a drawn-out state, is stored in the main body of the supply unit, the guide member comes into contact with the roll medium. The guide member is caused to be retracted downward from a travel path of the lower holding unit against a force pressing upward from below.

The plurality of support units are provided extending in the discharge direction, and are inclined downward in a gravitational direction from upstream to downstream in the discharge direction, and a first support unit and a second support unit arranged at a lower position in the gravitational direction with respect to the first support unit as viewed in the width direction, the first support unit and the second support unit being arranged alternatingly in the width direction.

Medium placement device

A medium placement device is configured to stack a plurality of sheets of a medium discharged from a discharge unit of a processing device. The medium placement device includes a plurality of support units being provided in a width direction intersecting with a discharge direction of the medium discharged from the discharge unit, and being configured to support the medium at a support surface from below in a gravitational direction. A first support unit and a second support unit are provided in an alternating manner in the width direction, the second support unit being arranged at a position lower than the first support unit in the gravitational direction when viewed in the width direction. The first support unit is provided with a bridging member configured to couple a lower side of the discharge unit in the gravitational direction and the support surface of the first support unit.

A recording device includes a recording unit, a support portion for supporting a recording medium, a transport path for transporting the recording medium, a recording medium holding unit for holding a roll body and supplying the recording medium, and a frame for holding thereof, wherein the frame includes a lower frame extending along an X direction and a Y direction, a pair of side frames extending along a Z direction and the Y direction, each including a lower end fixed to the lower frame and upright in the Z direction, and disposed at a predetermined interval in the X direction, and a base frame held between the pare of side frames and including four wall surfaces extending in the X direction, and functional components related to recording of the recording unit are disposed inside the four wall surfaces.

Recording device

A recording device includes a main body including a recording unit configured to perform recording on a medium pulled out from a roll body including the medium wound around a core member, and a leg part configured to support the main body from an installation surface on which the main body is installed. The leg part includes contact parts configured to make contact with the installation surface at respective positions different from each other. The contact parts include three reference contact parts located on a same plane and one movable contact part. The movable contact part is coupled with the main body through an elastic member that is elastically deformable in a direction that intersects the plane.

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.

Processing device and recording device including a medium receiving unit that receives a discharged medium

A recessed portion is a portion that is provided to an end of a platen in an X direction and is recessed from the supporting surface of the platen. A discharge portion discharges the ink in the recessed portion along a +Y direction. A width of the discharge portion in an X direction is smaller than a width of the recessed portion in the X direction, and a position of the discharge portion in the X direction is arranged on an inner side with respect to a position of an edge of the roll paper. An end side of the discharge path, which is positioned on an inner side of the roll paper in the X direction, is arranged continuously to an end side of the recessed portion, which is positioned on the inner side of the roll paper, on an extension line of the end side.

In a printer, an accommodating portion accommodates roll paper. A supply roller pair is disposed upstream of a recording unit in a transport direction, and nips the roll paper. The intermediate roller pair is rotatably disposed between the supply roller pair and the accommodating portion, and nips the roll paper. A second motor and a third motor apply tension to the roll paper between the intermediate roller pair and the accommodating portion. A control unit can switch between a first mode and a second mode. In the first mode, first tension is applied to the roll paper between the intermediate roller pair and the accommodating portion. In the second mode, second tension smaller than the first tension is applied.

Recording device and method of controlling recording device

A printer includes a transport unit, a recording unit, a cutter unit, and a control unit. The transport unit is capable of transporting two pieces of roll paper in parallel. The cutter unit is movable in a width direction intersecting a transport direction, and is capable of cutting the two pieces of roll paper. The cutter unit is capable of cutting roll paper PR in both a forward path and a return path of the movement in a width direction. The control unit is capable of setting a standby position of the cutter unit to a position between the two pieces of roll paper.

Recording device and control method for recording device

In a medium supply device, a receiving portion includes a support portion configured to rotatably support a spindle, and a drive gear meshing with a driven gear provided at the spindle to rotate the spindle, and a displacement member includes a pivoting shaft configured to pivot between an advanced position where the spindle is covered and a retracted position where the spindle is exposed, an abutting portion abutting the spindle when the spindle is installed at the receiving portion, the abutting portion being configured to cause the displacement member to pivot to the advanced position, an opposing portion abutting, at the advanced position, an outer peripheral surface of the spindle installed at the receiving portion, a cover portion configured to cover the driven gear, and a grounding member contacting the spindle, thereby coupling to a ground potential.

Medium supply device and recording device

Processing device and recording device

A transport device unwinds a medium from a roll body to which a shaft member is mounted and transports the medium.
