Abstract: A printer comprising a main unit, a cover, a first print head provided in the cover, a second print head provided in the main unit, and a hinge mechanism. The cover can rotate around the hinge mechanism, between a first state and a second state in which the cover is opened and closed, respectively, with respect to the main unit. The first print head and the second print head can rotate along the locus of the cover.

Abstract: A thermal printer includes a printer body, a cover attached to the printer body so as to be rockable between closed and open states, a platen roller provided on the printer body or cover, a thermal head provided on the cover or printer body and configured to be opposed to and press the platen roller when the cover is in the closed state, a first cutter provided on the printer body or cover and configured to cut a recording medium being transported on the downstream side of the printer body with respect to the thermal head, a second cutter provided on the cover or printer body and opposed to the first cutter when in the closed state, and a retraction mechanism configured to retract one of the first and second cutters from the other in association with a motion of the cover when the cover is closed.

Abstract: The apparatus has a carriage that holds a head, a carriage-driving mechanism having a motor, and a holding mechanism configured to press a recording medium to a medium-holding base. The holding mechanism has a pair of arm members and a pushing member secured to the arm members. A spring urges the holding mechanism toward the medium-holding base. The carriage can move to a first region and farther to as second region. In the first region, the head can read data from the recording medium. The apparatus has a sliding member that moves together with the carriage while the carriage remains in the second region. When the carriage moves to the second region and moves together with the carriage, the pushing member moves away from the medium-holding base.

Abstract: According to an aspect of the present invention, a thermal printer includes a housing in which a space is formed, printing means disposed in the housing, a cover disposed in the housing and which comes into contact with and separates from the housing when rotated, thereby opening and closing the space, urging means for urging the cover in a direction away from the housing, an engaging part which is disposed in the housing and which prevents the movement of the cover in a direction away from the housing when engaged with the cover, a pressed part which is disposed rotatably in the cover and which moves the engaging part when pressed, thereby releasing engagement between the cover and the engaging part, and elastic means arranged to urge the pressed part in a direction away from the engaging part.

Abstract: A thermal printer includes a first thermal head, a first platen roller, first biasing means, a second thermal head, a second platen roller, and second biasing means. The first thermal head, the first platen roller, the first biasing means are in contact with a heat-sensitive layer of thermal recording paper. The second thermal head, the second platen roller, and the second biasing means are in contact with a heat-sensitive layer of the thermal recording paper. The second thermal head is arranged on the upstream side of the first thermal head in a paper feed direction. A paper feed speed of the first platen roller to the thermal recording paper is larger than a paper feed speed of the second platen roller. The first platen roller is in contact with the thermal recording paper while being more slippery compared with the second platen roller.

Abstract: A printer having a hopper without shaft which performs a print operation on a roll of continuous paper. Detection marks are provided in flanges provided in supported members removably attached to the continuous paper, and the presence/absence of the detection mark in a detection position of an optical sensor is determined. A rear end of the continuous paper in the hopper is determined if the result of determination of the presence/absence of the detection mark during conveyance of the continuous paper is the same. A passage length from the position of the determined rear end of the continuous paper to a print unit is equal to or longer than a predetermined maximum print size. By this arrangement, the rear end of the continuous paper can be detected without upsizing the apparatus and without complicating the structure, and the continuous paper can be effectively utilized without causing shortage of the continuous paper during execution of print operation.

Abstract: A printer comprising a printing section which performs a printing operation for receipt paper, a slider whose surface forms a paper conveying path for the conveyance of the receipt paper after printing, and a conveyance section which conveys the receipt paper after printing by means of a conveyor belt, the conveyor belt being stretched between and entrained on a driving pulley which is rotationally driven and a driven pulley and located at a position at which it comes into abutment against the slider through the paper conveying path, wherein the slider is formed so as to make almost uniform a pressing force applied from the conveyor belt, and the conveyor belt slips relative to the receipt paper when the movement of the receipt paper being conveyed is obstructed. According to this construction, when the movement of the receipt paper is obstructed, the receipt paper stands by between the conveyor belt and the slider, so that occurrence of paper jam can be surely prevented.
