The present disclosure relates to a printer for pulling out a paper wound in the form of a wound roll, and more particularly, to a printer which includes a cartridge configured to accommodate the paper, a housing in which the cartridge is mounted, and a printing part configured to pull out the paper. The cartridge or the housing has a decurling part formed thereon, and the decurling part comes into surface-contact with the paper on the upper side of the paper in the process of pulling out the paper.

A printing apparatus includes a printing head that performs printing in a printing region of a first surface of a medium, a support portion that supports a second surface of a medium, a transport unit that transports the medium in a transport direction, and a static electricity eliminating material that is provided facing the second surface and that eliminates, in a non-contact manner with the medium, static electricity accumulated in the medium. The support portion includes a spacer that maintains a predetermined distance between the medium and the static electricity eliminating material.

A paper compartment in which roll paper can be held has an opening positioned along the second axial end of the roll paper and a wall positioned along the first axial end of the roll paper in the axial direction. The paper loading member can be removably installed in the paper compartment through the opening. The paper loading member has a flange and a roll support member that projects from the flange and is inserted into the paper. When roll paper is held in the paper compartment, the paper loading member is installed in the paper compartment with a first side of the flange contacting the first axial end of the paper, and the roll support member is inserted into the roll paper. When the paper loading member is installed in the paper compartment, the first side of the flange faces the opening.

An arrangement includes a receipt printer for printing a receipt arranged in a housing. The housing includes a pivoting lid which in an open state allows access to the receipt printer and in a closed state prevents access to the receipt printer. The lid has an opening through which a receipt printed by the receipt printer can be output in the closed state. The arrangement has a receipt output unit which in the closed state is arranged in the opening of the lid opposite to the receipt printer, at least a first receipt guiding unit and at least a first elastically deformable element for spring-mounting at least one component of the first receipt guiding unit. The receipt printer has a second receipt guiding unit. The first receipt guiding unit is engaged with the second receipt guiding unit when the lid is moved from the open state into the closed state.

A printing apparatus includes a transport unit configured to transport a medium, a winding unit disposed downstream, in a transport direction, of the transport unit, the winding unit being configured to wind the medium, and a tension applying unit including a rod member biased toward the medium between the transport unit and the winding unit, the rod member being for applying a tension to the medium. The tension applying unit is configured so that the rod member moves along a predetermined direction as at least one of the transport unit and the winding unit is driven to transport the medium. An upper limit position of a movement of the tension bar along the predetermined axis is changed according to a winding mode of the winding unit.

A printer device includes a guide section, a first projecting section, and a second projecting section. The guide section is disposed to be opposed to a side surface of roll-like continuous paper and includes a guide surface for restricting movement of the continuous paper along a width direction of the continuous paper during conveyance of the continuous paper. The first projecting section is provided on the guide surface side of the guide section and rotatably holds a core section of the continuous paper. The second projecting section has an outer diameter larger than an outer diameter of the first projecting section and is movable between a supporting position where the second projecting section contains an outer circumference of the first projecting section and a storing position where the second projecting section is stored further on an inner side than the guide surface. In the supporting position, the second projecting section rotatably holds a core section of another continuous paper having a core diameter larger than a core diameter of the continuous paper.

According to an aspect of the present disclosure, a printing apparatus includes a conveyance unit configured to convey a sheet in a conveyance direction, a print head configured to perform printing on the sheet conveyed in the conveyance direction by the conveyance unit, a discharge port from which the sheet printed by the print head is discharged, a stacking portion located below the discharge port and configured to stack the sheet discharged from the discharge port in a state where a leading end of the sheet is directed to an upstream side in the conveyance direction, and a holding unit disposed in a sheet discharge path below the discharge port and configured to move between a holding position in which the holding unit holds the sheet and a releasing position in which the holding unit releases the sheet.

A print medium feeding device removes a second sheet from a print medium that is in a state in which a first sheet, the second sheet, a the third sheet are superposed, superposes the first sheet and the third sheet, and feeds the first sheet and the third sheet to a printing device. The print medium feeding device includes: a first roller configured to come into contact with the third sheet and to be driven to rotate by movement of the third sheet; a second roller configured to come into contact with the first sheet and to be driven to rotate by movement of the first sheet; a roll-up member disposed upstream of the first roller and configured to roll up the second sheet; and a transmission mechanism configured to transmit a rotational force of the first roller to the roll-up member.

A printer device includes a main housing including a print media cassette receiving slot. A first drive assembly of the main housing includes a motor operatively coupled to rotate a drive gear. A print media cassette is removably inserted into the print media cassette receiving slot, and includes a second drive assembly having a driven gear that is engaged with the drive gear. One of the drive gear or the driven gear is mounted for movement such that at least one of (i) a position of an axis of the drive gear is movable relative to the main housing or (ii) a position of an axis of the driven gear is movable relative to the printer cassette. A retaining mechanism includes a portion movable into a gear train coupling position in which the drive gear and the driven gear are held in driving contact with each other.
