Abstract: A printer includes a platen roller, a substrate, a heating element, a first defining part, and a second defining part. The platen roller conveys a medium in a conveyance direction. The substrate has a front surface which faces the platen roller in a facing direction intersecting an axis direction of the platen roller and the conveyance direction. The heating element is provided on the front surface of the substrate. The heat sink is in contact with a back surface of the substrate. The first defining part and the second defining part define the conveyance path. The first defining part is provided on a further upstream side than the heating element in the conveyance direction. The second defining part is provided at the heat sink on a further downstream side than the substrate in the conveyance direction. and has a contact surface with which the medium comes into contact.

Abstract: A print device includes a head unit holding a heat sink, a head holding member holding the head unit, a platen roller, a support shaft supporting the head holding member to pivot between a close position and a separated position, an urging member, and an adjustment mechanism including an adjustment shaft and an eccentric cam. The separated position is a position where the print head is separated from the platen roller than the close position. The urging member urges the head unit and applies a pressing load pressing the print head against the platen roller. The eccentric cam rotates around the adjustment shaft and coming into contact with the head holding member in a state of being offset with respect to the adjustment shaft. The adjustment mechanism adjusts a position of heating elements of the heat sink with respect to the platen roller by rotating of the eccentric cam.

Abstract: A printing device includes: a main body including an accommodating portion configured to accommodate a printing medium; a cover displaceable between an open position where the accommodation portion is opened and a closed position where the accommodation portion is closed; a platen roller attached to the cover and rotatably supported by the cover; a peeling roller attached to the cover and supported so as to be rotatable about an axis parallel to a longitudinal direction of the platen roller; and a switching mechanism attached to the cover and configured to switch the peeling roller between a contact position where the peeling roller comes into contact with the platen roller and a non-contact position where the peeling roller is away from the platen roller in conjunction with displacement of the cover.

Abstract: There is provided a printing device to which an external component is attachable. The printing device includes: a housing; a print head provided inside the housing; a guide portion configured to guide a printing medium to the print head in a conveying direction; and a first engagement portion engageable with a first attaching portion of the external component. The housing includes a first frame, a second frame opposite the first frame in a widthwise direction crossing the conveying direction, and a connecting portion extending in the widthwise direction to connect the first frame to the second frame. The print head is supported by at least one of the first frame and the second frame. The guide portion is fixed to the connecting portion. The first engagement portion is formed in one of the guide portion and the connecting portion.

Abstract: A printer includes: a casing; a grooved part recessed from an outer surface of the casing; a switch unit provided in the grooved part; a controller inside the casing; an FPC connecting the switch unit to the controller; and a hole part formed at a prescribed end portion of a bottom surface of the grooved part. A bottom surface of the switch unit is fixed to the groove bottom surface through the FPC. The hole part is aligned with a center of the groove bottom surface in a prescribed direction. The hole part defines a first inner end and a second inner end opposing each other in the prescribed direction, the first inner end being farther away from the center of the groove bottom surface than the second inner end is in the prescribed direction. The first inner end is positioned outside of the grooved part in the prescribed direction.

Abstract: A printer includes: a print head; a support frame elongated in a first direction and supporting the print head; a discharge slot for discharging a medium after printing is performed on the medium; and a cover member covering the print head and the support frame. The discharge slot and the cover member are both elongated in the first direction. The cover member includes a surrounding part and a first engagement portion. The surrounding part surrounds an entirety of the discharge slot and has a peripheral portion extending in the first direction and constituting a part of the discharge slot. The first engagement portion is in engagement with a frame engagement portion of the support frame.
