Abstract: A paper discharge apparatus includes a conveying path configured to convey a paper from an upstream portion to a downstream portion. A preventing mechanism is provided on the conveying path. The preventing mechanism is configured to prevent the paper from being conveyed to the downstream portion by pushing the paper or blocking the conveying path. A control unit is configured to bend the paper by preventing the conveyance of the paper by using the preventing mechanism, and then convey the paper to the downstream portion of the conveying path for discharge of the paper from the conveying path.

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 includes a housing, a drawer unit, first and second print medium supporting units, a third support, and a printing unit. The drawer unit is placed inside the housing so that it can be drawn out from the housing into open and closed positions. The first print medium supporting unit is fixed to the drawer unit and spaced apart from the second print medium supporting unit. The upper end of the second print medium supporting unit is fixed to the drawer unit and its lower end rotates with respect thereto. The third support is disposed in the housing and supports the lower end of the second print medium supporting unit when the drawer unit is in a closed position. The printing unit can print on a print medium pulled out from the rolled print medium which is rotatably supported by at least the first print medium supporting unit.
