A printing device for printing on a label sheet includes a first print head to perform printing on a first side of a label sheet being conveyed along a conveyance path. The label sheet is interposed between the first print head and a first roller. A second print head is upstream of the first print head and performs printing on a second side of the label sheet. A second roller is adjacent the second print head across the conveyance path. A cutter is downstream of the first print head to cut off a first portion of the label sheet. A processor is configured to cause the label sheet to be conveyed in a second direction after the first portion is cut off from the sheet so that the cut end of the sheet reaches the first print head.

Printer device

A printer includes a body including a label sheet storage location and a cover rotatably attached to the body and covering the storage location when closed. The cover includes a roller having a shaft that is used for conveying the label sheet when the cover is closed and a peeling bar extending above the roller. The body includes a pressing member extending along the direction and pressing the sheet against the bar for peeling a label from the label sheet and a release lever arranged at an end of the pressing member. The release lever has a recess and rotates between a first position at which the shaft fits into the recess and a second position at which the shaft is released. The release lever rotates from the first to second positions to open the cover when a release button is pressed.

A portable thermal printer includes a housing and an anti-skew unit. The housing is provided with a thermal printer head and a platen roller, and is configured to convey a paper between the thermal printer head and the platen roller. The anti-skew unit inside the housing is configured to contact both side edges of the paper in a width direction to prevent the paper, which is being conveyed, from skewing, and the setting of the width of the paper by the anti-skew unit is configured to be adjustable from outside the housing.

Portable thermal printer

A printer comprises a paper holding section, a printing and conveying section, a buffer section and a movable section. The paper holding section holds the paper rolled into a roll such that can draw out and convey the paper. The printing and conveying section, which is provided with a print head and a platen roller that are arranged opposite to each other, draws out and conveys the paper and then prints on the paper. The buffer section arranged at the downstream side of the paper conveying direction of the paper holding section and the upstream side of the paper conveying direction of the printing and conveying section to elastically press the paper surface of the paper.

A printer comprises a paper holding section, a conveying section, a printing section and a buffer section. The buffer section, which is arranged at the downstream side of the paper conveying direction of the paper holding section and the upstream side of the paper conveying direction of the conveying section, extends in the width direction of the paper orthogonal to the paper conveying direction and has a propping member that is propped against the paper surface of paper and a pair of elastic support sections that are connected with the two ends of the propping member in the width direction and press the propping member on the paper surface of the paper using an elastic force, wherein the pair of elastic support sections are connected with the propping member in such a manner that each of the elastic support sections can act separately.

In a rewritable printer of one embodiment which reprints information on a rewritable paper with a thermal print system after erasing by heat information printed on the rewritable paper and discharges it to the outside of the printer through a paper issue port, the printer includes an auxiliary guide having a smooth surface, provided at the paper issue port, to guide the rewritable paper, on which information is reprinted, discharged to the outside.

According to one embodiment, a portable thermal printer is disclosed. The portable thermal printer comprises: a housing provided with a thermal printer head; a cover openably attached to an opening portion of the housing by a pivotal shaft, the cover being provided with a platen roller arranged to make contact with the thermal printer head when the opening portion of the housing is closed by the cover; and a drive power source provided within the housing. The drive power source, the pivotal shaft and the platen roller are connected by a belt mechanism.

According to one embodiment, a printer includes a thermal head, a platen roller, and an urging mechanism configured to urge the thermal head against the platen roller. The printer further includes a first separation mechanism configured to move the thermal head from a proximal position where the thermal head is placed adjacent to the platen roller, to a first separation position where the thermal head is placed farther away from the platen roller than the proximal position, and a second separation mechanism configured to move the thermal head from the proximal position to a second separation position where the thermal head is placed farther away from the platen roller than the proximal position and placed closer to the platen roller than the first separation position. The printer further includes an electric-powered actuator having a movable member configured to reciprocate along a lengthwise direction of the printing medium.

A portable printer includes: a housing; a platen roller configured to convey a label sheet having a base sheet; a pinch roller configured to rotate following the platen roller via the base sheet; a supporting shaft configured to support the pinch roller; a shaft holder configured to hold the supporting shaft; a removing and inserting section configured to hold the shaft holder to be removable therefrom and insertable thereinto; a pawl section provided in the shaft holder, configured to resiliently hook to the removing and inserting section; a member holding section provided in the housing; and an urging member detachably attachable to the member holding section, nipped by the member holding section and the supporting shaft, and configured to apply pressing force on the platen roller to the pinch roller.

Portable printer

By rotating an antenna movable screw, an antenna fixing plate is vertically moved through the screw action, whereby the position of the antenna is changed. With this mechanism, the distance between the antenna and a transported label sheet can be adjusted according to a type of a label sheet (RF tag), whereby information can correctly be written to a tag corresponding to the type of various label sheets (RF tags).
