Abstract: A thermal printer includes a frame, a platen roller supported on the frame so as to be rotatable about a first direction, a head support plate supported on the frame, and a thermal head fixed to the head support plate. The head nips paper between the roller in a second direction orthogonal to the first direction. The frame includes a swing support portion supporting the plate so that the plate is swingable about the first direction and a third direction orthogonal to the first direction and the second direction. The head is fixed to a portion of the plate located on a first side in the third direction with respect to the swing support portion. Between a portion of the plate located on a second side and the frame, an urging member configured to urge the plate in a direction of causing the head to approach the roller is interposed.

Abstract: A thermal printer module includes: a housing; a cover; a platen roller provided to the cover; a support frame having a groove configured to receive a shaft of the platen roller; a lock arm configured to hold down, by a platen roller engagement portion, the shaft of the platen roller inserted into the groove; a biasing member configured to apply a biasing force to the lock arm; and a printing head. Wherein, when viewed in a direction extending along an axis of the shaft, the platen roller engagement portion and a tangential line of a track obtained when the axis of the shaft moves along with an opening operation of the cover form an intersection angleθAB in a closing direction of the lock arm, and the intersection angle θAB satisfies a relation of 90°≤θAB≤110°. Wherein the platen roller engagement portion and a tangential line of a track obtained when a contact point between the shaft and the platen roller engagement portion pivots in an unlocking direction of the lock arm form an intersection angle θBC in the closing direction of the lock arm, and the intersection angle θBC satisfies a relation of 0°≤θBC≤10°.

Abstract: A thermal printer includes a platen roller, a thermal head, a head support plate, a frame including a platen roller support portion, a turn support portion configured to support the head support plate, and an urging member configured to urge the head support plate in a direction in which the thermal head approaches the platen roller. The thermal head is fixed to an opposed surface of the head support plate, which is in a first region located on one side with respect to the turn support portion, and is opposed to the platen roller in the first direction. The urging member is interposed between the opposed surface of the head support plate in a second region, which is located on another side with respect to the turn support portion and an urging member support portion of the frame.

Abstract: A printer for printing information on a recording sheet, includes a housing configured to accommodate a recording sheet and a printing portion; a battery to be removably mounted to the housing; and a clip pivotably mounted to the housing. The clip includes a joint portion, which is elastically deformable so that a coupling portion of the housing is pivotably fitted to the joint portion. Each of the joint portion and the coupling portion includes an engagement portion configured to restrain the clip from pivoting at a mounting position at which the clip covers at least a part of the battery. When a predetermined external force is applied to the housing in a pivoting direction of the clip, restraining of the clip by the engagement portions is canceled so that the clip is movable from the mounting position.

Abstract: A thermal printer includes a head block having a head support plate and a thermal head fixed to the head support plate, a platen roller brought into abutment against the thermal head through intermediation of recording paper, a wiring board drawn from the thermal head, a frame supporting the platen roller and the head support plate, and a recording paper sensor mounted to the wiring board and detecting the recording paper. The frame includes a guide wall arranged on upstream of the thermal head in a conveyance direction of the recording paper, the guide wall guiding the recording paper to the thermal head. The head block including a sensor holder mounted thereto, the sensor holder holding the recording paper sensor at a portion which is located between the thermal head and the guide wall in the conveyance direction.
