    Abstract: The present disclosure provides a thermal print head. The thermal print head includes a substrate having a main surface and a convex portion and including a semiconductor material; a resistor layer including a plurality of heat generating portions located on the convex portion; and a wiring layer conducted to the plurality of heat generating portions and formed to contact the resistor layer. The convex portion has a top surface, a first inclined surface and a second inclined surface. The first inclined surface and the second inclined surface are disposed between the main surface and the top surface, separated from each other in a sub-scanning direction, and tilted with respect to the main surface. A first tilted angle of the first inclined surface with respect to the main surface and a second tilted angle of the second inclined surface with respect to the main surface are greater than 55 degrees.

    Abstract: A thermal head and a printer head are disclosed. The thermal head includes heat generating members, a drive IC disposed, pads and interconnection lines which are all disposed on a substrate. The heat generating members are arranged in a first direction. The drive IC is operable to control driving of the heat generating members. The pads are operable to being electrically connected to terminals of the drive IC. The interconnection lines electrically connect each of the heat generating members to one of the pads. The pads are arranged in a first direction and constitute first pad groups and second pad groups constituted by the pads that constitute the first pad groups. The second pad groups are arranged in the first direction so as to be shifted from each other in a second direction that differs from the first direction.

    Abstract: A thermal printer according to an embodiment includes: a platen that has a rotatable columnar shape and that is configured to convey a print medium having various widths, with a central portion in a direction of a rotary shaft as a reference, in a manner of being in contact with an outer peripheral portion; and a print head that is oppositely disposed along the platen, that is pressed by the outer peripheral portion, and that is configured to perform printing by applying heat to the print medium. The platen includes a shaft constituting the rotary shaft and a rubber including the outer peripheral portion provided on an outer periphery of the shaft, and has a first region centered on the central portion and second regions on both outer sides in the direction of a rotary shaft with respect to the first region. A diameter of the platen in the first region and diameters of the platen in the second regions are the same, and a thickness of the rubber in the first region is smaller than thicknesses of the rubber in the second regions.

    Abstract: A printer includes a casing in which a confronting portion is provided between a platen roller and a thermal line head. The casing has an opening. A guide member provides an inlet passage in the casing and includes a plurality of ribs and a flat surface portion. The ribs are spaced away from each other in a widthwise direction of a sheet. The ribs are in contact with the sheet to guide the sheet. The flat surface portion is positioned at a portion other than the plurality of ribs. An optical sensor is provided to optically detect the sheet. A light shielding member is provided in the casing and protrudes toward the inlet passage at a position closer to the opening than the optical sensor to the opening. The light shielding member has a protruding end in intimate contact with the flat surface portion.
