  • Patent number: 8616878
    Abstract: A heat-sensitive adhesive label manufacturing device has a thermal head for heating and thermally activating the heat-sensitive adhesive layer of a heat-sensitive adhesive sheet, and a platen roller for conveying the heat-sensitive adhesive sheet between the platen roller and the thermal head to transport the heat-sensitive adhesive sheet in a transport direction. At least one discharge roller is disposed on a downstream side of the thermal activation section and is configured to undergo rotation at a peripheral speed different from a peripheral speed of the platen roller to convey the heat-sensitive adhesive sheet in the transport direction. A guide member is disposed opposite and spaced apart from the at least one discharge roller to provide a space therebetween along which the heat-sensitive adhesive sheet is conveyed by the at least one discharge roller without being sandwiched between the at least one discharge roller and the guide member.

  • Patent number: 8353511
    Abstract: A paper discharge device includes a waiting path, one side of which is connected to an input port and another side of which is connected to a discharge port. A collection path has one side connected to the waiting path through a merged portion and another side connected to a collection chamber. Conveyance mechanisms disposed along the waiting path convey a paper which was conveyed through the input port to the discharge port in a forward direction, and convey, after lapse of a given period of time after conveyance of the paper to the discharge port, the paper in a reverse direction through the merged portion to feed into the collection path. The waiting path has a downward curvature between the merged portion and the discharge port.

    Abstract: A paper discharge device includes a waiting path having one side connected to an input port and another side connected to a discharge port, and a collection path having one side connected to the waiting path through a merged portion and another side connected to a collection chamber. Conveyance mechanisms convey a paper which was conveyed through the input port to the discharge port in a forward direction, and convey, after lapse of a given period of time after the conveyance of the paper, the paper in a reverse direction through the merged portion to feed into the collection path. An input mechanism provided in the collection path conveys the paper fed from the waiting path through the collection path into the collection chamber while sandwiching the paper between rollers to form folds across a total length of the paper along the paper conveying direction.

  • Publication number: 20100183995
    Abstract: A heat-sensitive adhesive label manufacturing device includes: a thermal head (3) (thermal activation unit) for thermally activating a heat-sensitive adhesive layer while being in contact therewith; a platen roller (4) which is situated opposed to the thermal head (3); and a discharge roller (5) which is situated on a downstream side of the thermal head (3) and the platen roller (4) and rotates at a peripheral speed different from a peripheral speed of the platen roller (4). When the discharge roller (5) includes a plurality of discharge rollers (5), at least a discharge roller (5) closest to the thermal head (3) and the platen roller (4) is rotated at the peripheral speed different from the peripheral speed of the platen roller (4).

  • Patent number: 7001089
    Abstract: A thermal printer has a main body frame and a platen roller rotatably and removably mounted in a preselected position on the main body frame. A thermal head is mounted on the main body frame for movement into and out of pressure contact with the platen roller during a printing operation and while the platen roller is in the preselected position for recording printing data on a recording medium disposed between the thermal head and the platen roller. A detecting device detects a preselected state of the thermal printer in which the platen roller is in the preselected position and in which the recording medium is disposed between the platen roller and the thermal head.

  • Publication number: 20040234314
    Abstract: In order to provide a thermal printer which performs detection of the presence or absence of recording paper and detection of the attachment/detachment states of a platen roller with reliability using only one sensor and which has such a simple structure that it can be diverted to any kind system merely by changing some components, the thermal printer of the present invention comprises a main body frame, a thermal head for performing printing on recording paper and a head supporting member integrally provided at the back of the thermal head, a platen roller placed side by side with the thermal head, a bearing portion for rotatably and attachably/detachably supporting the platen roller; an urging unit for urging the thermal head in a direction in which the thermal head is brought into pressure contact with the platen roller, and a load detection type sensor provided at a position at which under a state where the recording paper exists below the platen roller and a shaft of the platen roller is supported by the
