Disclosed are a sheet material stocking mechanism providing a large stocking capacity with a small space and a printer equipped with such a stocking mechanism. A thermal printer is composed of a roll accommodating unit (2) retaining a heat sensitive adhesive sheet (1) wound into a roll, a printing unit including a printing thermal head (4) for performing printing on the heat sensitive adhesive sheet (1), a cutter unit (3) for cutting the heat sensitive adhesive sheet (1), a stocking unit including a take-up device (10) which takes up the heat sensitive adhesive sheet (1) that has undergone printing in a cylindrical form to stock it temporarily, and a thermal activation unit including a thermal activation thermal head (6) that thermally activates a heat sensitive adhesive agent layer of the heat sensitive adhesive sheet (1).
摘要:
A heat-sensitive adhesive sheet is thermally activated thoroughly at both ends in a conveying direction and unnecessary heating from heat accumulated in a platen roller is avoided. Driving of heating elements (10) of a thermal activation thermal head is started (T3) before the front end of a heat-sensitive adhesive sheet (1) in a sheet conveying direction enters between the thermal head and a platen roller (12) (T2). A heat-sensitive adhesive layer is thermally activated until the heat-sensitive adhesive sheet is sent past the heat-sensitive adhesive sheet (1). Driving of the heating elements (10) is stopped (T6) after the rear end of the heat-sensitive adhesive sheet (1) departs from between the thermal head and the platen roller 12 (T5). The time period from the start of driving of the heating elements (10) to the entrance of the front end of the heat-sensitive adhesive sheet (1) between the thermal head and the platen roller (12) (T2-T3), and the time period from the departure of the rear end from between the thermal head and the platen roller (12) to the end of driving of the heating elements (10) (T6-T5), are each set shorter than the one it takes for the platen roller (12) to rotate once.
摘要:
A heat-sensitive adhesive layer is thermally activated to develop satisfactory adhesion at improved energy efficiency. A thermal activation thermal head is driven in sync with movement of a heat-sensitive adhesive sheet conveyed, and chosen heating elements stop being driven at a given timing. For instance, while moving the heat-sensitive adhesive sheet, driving of three heating elements (10B, 10F and 10J) and driving of two heating elements (10D and 10H) are alternately stopped whereas five heating elements (10A, 10C, 10E, 10G and 10I) are driven all the time. Supposing that the entire surface of a heat-sensitive adhesive layer is gridded to form a matrix, a region (15A) that is directly heated by none of the opposing heating elements 10 is placed regularly in a manner that makes its surrounding regions (15B to 15I) heated directly by the opposing heating elements. The directly heated regions (15B to 15I) are activated by the opposing heating elements (10) whereas the indirectly heated region (15A) is activated by heat transmitted from the surrounding regions (15B to 15I).
摘要:
A cutter mechanism has a fixed blade and slidable blade which cooperates with the fixed blade to cut a recording sheet. The fixed blade is biased in a direction away from a base portion by a biasing member. A holder supports the fixed blade away from the base portion to cause a cutting edge of the fixed blade to swing up and down and permit opposite ends of the fixed blade to be pushed down at least in the direction of the base portion. The fixed blade holder has a wall portion positioning the fixed blade in a sliding direction of the slidable blade, a first regulating member that regulates lifting of the fixed blade cutting edge, and a second regulating member that regulates lifting of the fixed blade root portion in a state in which a gap is formed between the base portion and the root portion.

摘要:
A thermal head has heating elements that can be selectively driven independently from one another during a driving operation to directly heat, and thereby thermally activate, regions of a heat-sensitive adhesive layer of a heat-sensitive adhesive sheet while the heat-sensitive adhesive sheet is moved relative to the thermal head with the heating elements disposed in opposing relation to the respective regions of the heat-sensitive adhesive layer. All but at least one of the heating elements are selectively driven so that (a) a preselected region of the heat-sensitive adhesive layer disposed in opposing relation to each non-driven heating element is not directly heated, and thereby not directly thermally activated, by the non-driven heating element, (b) the regions of the heat-sensitive adhesive layer disposed in opposing relation to the respective driven heating elements are directly heated, and thereby directly thermally activated, by the respective driven heating elements, and (c) each preselected region of the heat-sensitive adhesive layer opposed to a non-driven heating element is thermally activated with heat transmitted from surrounding directly heated regions of the heat-sensitive adhesive layer of the heat-sensitive adhesive sheet.
