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.

Adhesive label manufacturing device and adhesive label manufacturing method

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.

Paper discharge device

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.

Provided is a printer that employs a platen roller as conveying means, for which the accuracy of the assembly of the constituents of a drive transmission mechanism that drives a platen roller is increased, and the heat releasing function of a motor that is a drive source is also improved, so that downsizing and increasing output can be coped with. Therefore, according to the present invention, a printer comprises: a platen roller, for conveying a recording sheet, a print head, arranged opposite the platen roller, a drive unit, for rotating the platen roller, and a main frame, including a pair of side walls that can rotatably support the platen roller, wherein the drive unit includes: a motor; idler gears, for transmitting a rotational force provided by the motor to the platen roller; and a gear fitting member, integrally formed with gear support shafts that support the idler gears, wherein the motor and idler gears are capable of being mounted in the main frame while attached to the gear fitting member, and wherein a drive gear of the motor and the idler gears are stored in a space defined by the gear fitting member and one of the side walls of the main frame.

Provided is a thermal printer including: a thermal head having a plurality of heating elements; a head support member, which is conductive, for supporting the thermal head; a platen roller whose circumferential surface can be brought into contact with the thermal head while nipping a recording paper; biasing members, which are conductive, provided between the case and the head support member, for supporting the head support member while imparting bias toward the platen roller; and a flexible substrate electrically connected with the thermal head to transmit a signal, in which a part of the biasing member extends through the flexible substrate and is grounded by fixation while being electrically connected by solder with respect to the flexible substrate.

Thermal printer

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.
