Provided is a printing apparatus including: a holder unit provided with a holding member, a contact portion, and a shaft member, and an apparatus body provided with a support portion, and a fixing portion, wherein the shaft member is configured to be detachably attached to the support portion, the holder unit is configured to be rotatable between a first position and a second position with reference to the shaft member in a state where the shaft member is supported on the support portion, the first position is a position where the shaft member is attached to the support portion, and the second position is a position where the apparatus body fixes the holder unit by the fixing portion, the second position being a position where the contact portion is separated from the installation surface.

A printer includes a case including an input port for rolled paper, a cover provided to be rotatable between a closed position of the input port and an open position of the input port, a holding portion that holds the rolled paper, a biasing member that biases the holding portion in a first direction, a stopper mechanism that stops rotation of the holding portion in the first direction, and a linkage mechanism that rotates the holding portion in conjunction with the rotation of the cover. When the cover is in the closed position, the holding portion rotates in the first direction in accordance with an outer diameter of the rolled paper by a biasing force of the biasing member. When the cover rotates from the closed position to the open position, the holding portion rotates together with the cover against the biasing force of the biasing member.

A dual roll laminating film cartridge refill for a reusable cartridge loadable in a laminating machine. The refill includes a first roll of continuous adhesive-coated translucent laminating film having a first axial end and a second axial end. The refill includes a second roll of continuous adhesive-coated translucent laminating film having a first axial end and a second axial end. A first connector couples the first axial ends of the first and second rolls at a predefined gap distance. A second connector is independent from and spaced from the first connector, the second connector coupling the second axial ends of the first and second rolls at the predefined gap distance. The first and second connectors are uniquely shaped and asymmetrical to provide a keyed interface to the reusable cartridge.

A thermal-transfer printing apparatus includes a roll-paper-supplying unit that rotates an image-receiving paper roll and unwinds and winds a roll type of first image-receiving paper, and a print unit that includes a thermal head for heating a thermal transfer sheet and that forms an image by transferring a color material from the thermal transfer sheet to the first image-receiving paper. With the image-receiving paper roll removed, a reverse unit that reverses a sheet type of second image-receiving paper is mountable in a region in which the image-receiving paper roll used to be contained. The print unit forms the image on the first image-receiving paper in a first printing mode in which the image-receiving paper roll is contained in the region, and the print unit forms an image on both surfaces of the second image-receiving paper in a second printing mode in which the reverse unit is mounted on the region.

A sheet conveyance apparatus includes a storage unit storing a sheet, a conveyance member to convey a sheet, a support shaft portion, and a separation unit. The support shaft portion has one end fixed to a main body of the sheet conveyance apparatus and the other end as a free end that is not fixed to the main body. The separation unit pinches and conveys a sheet with the conveyance member and separates a plurality of sheets stored in and fed from the storage unit one by one. The separation unit includes a separation member that is supported by the support shaft portion and rotatable with the support shaft portion, and a holding member to hold the separation member. By moving the holding member in an axial direction of the support shaft portion, the separation unit is removed from the apparatus with the holding member holding the separation member.

A coil feeding device and a graphic machine thereof are provided. The coil feeding device includes a roller mechanism for carrying a coiled material, a base mechanism, and a compression rod mechanism. The roller mechanism includes a shaft penetrating through the shaft hole and a tension structure disposed on the shaft. The tension structure includes a first sleeve, a second sleeve and a tapered fixing member. When the first sleeve and the second sleeve are fixed to each other, the tapered fixing member holds the shaft to achieve mutual fixation of the coiled material and the shaft. By providing the second sleeve, the first sleeve and the tapered fixing member that cooperate with each other, the coiled material and the shaft are fastened to each other quickly, thereby improving production efficiency. Through the base mechanism, the coil feeding device is directly used on existing graphic machine for material processing.

A processing line processes logs of convolutely wound web material and has upstream and downstream sections. A main accumulator has buckets that receive, hold, and release logs. An input feeder receives logs from the upstream section and conveys them to a bucket of main accumulator. A loader has a loader accumulator and loader buckets that receive, hold, and release logs. A transfer conveyor between the main accumulator and the loader receives a log from the main accumulator bucket and conveys the log a loader bucket independently of the input feeder. The loader receives a log from the transfer conveyor. The loader conveys the log in the loader bucket to a discharge of the loader. The loader discharge discharges the log from the loader bucket to the downstream section of the processing line.

A recording apparatus includes a printing unit that performs a recording on a sheet, a third sheet feed unit that mounts a roll body on which the sheet is wound in a roll shape, unwinds the sheet from the roll body, and supplies the sheet to the printing unit, and a pressing portion that presses the roll body mounted on the third sheet feed unit, in which the pressing portion presses the mounted roll body in a direction opposite to a direction of taking out the roll body from the third sheet feed unit.

The tape cartridge including a roll body around which the tape is wound in a roll shape, a cartridge case in which the roll body is accommodated and which is common to the plurality of types of the tape cartridges, a spacer portion that is provided between the cartridge ease and a first end surface which is one end surface of the roll body, and has a varying size in a tape width direction depending on the type of the tape cartridge such that a position of the center of the tape is common to the plurality of types of the tape cartridges in the tape width direction, and an urging member that is provided between the cartridge case and a second end surface which is another end surface of the roll body and urges the roll body and urges the roll body to a first end surface side.

A sheet conveyance apparatus includes a storage unit storing a sheet, a conveyance member to convey a sheet, a support shaft portion, and a separation unit. The support shaft portion has one end fixed to a main body of the sheet conveyance apparatus and the other end as a free end that is not fixed to the main body. The separation unit pinches and conveys a sheet with the conveyance member and separates a plurality of sheets stored in and fed from the storage unit one by one. The separation unit includes a separation member that is supported by the support shaft portion and rotatable with the support shaft portion, and a holding member to hold the separation member. By moving the holding member in an axial direction of the support shaft portion, the separation unit is removed from the apparatus with the holding member holding the separation member.
