摘要:
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.

First and second sensors are disposed downstream and upstream of a conveyance path, respectively. A first head is disposed between the first sensor and the second sensor opposite to a first platen with the conveyance path interposed between the first head and the first platen. The first head pressurizing force adjusting device adjusts a pressurizing force of the first head to the first platen. A second head is disposed between the first head and the second sensor opposite to a second platen with the conveyance path interposed between the second head and the second platen. The second head pressurizing force adjusting device adjusts a pressurizing force of the second head to the second platen. The control unit controls the second head pressurizing force adjusting device to separate the second head from the second platen if a tailing end of the recording medium escapes from the second sensor.

According to one embodiment, an image forming apparatus includes a first sensor, a second sensor, a first head, a first head pressurizing force adjusting device, a second head, a second head pressurizing force adjusting device, and a control unit. The first and second sensors detect a recording medium. The first head forms an image on a first surface of the recording medium and the second head forms an image on a second surface of the recording medium. The first head pressurizing force adjusting device adjusts a pressurizing force of the first head to the first platen and the second head pressurizing force adjusting device adjusts a pressurizing force of the second head to the second platen. The control unit controls the first head pressurizing force adjusting device and the second head pressurizing force adjusting device based on outputs of the first and second sensors.

According to one embodiment, a medium detecting method includes conveying a medium in a first direction along a first conveying path, and allowing the medium conveyed from the first conveying path to enter a second conveying path arranged with the first conveying path so that the medium is conveyed in a second direction opposite to the first direction. The method also includes allowing light emitting elements of first and second detecting sensors to irradiate light such that the light intersects the first and second conveying paths, and detecting the presence or absence of the medium based on whether or not light receiving elements of the first and second detecting sensors receive the light.

A printer according to an embodiment of the present invention is a printer which transports a recording medium, provided with a plurality of laminated sheets, along a predetermined transport path including a curved portion. The printer is provided with a dot head for printing the recording medium, a platen roller which faces the dot head with the recording medium therebetween, and a feed guide which is located on the downstream side of the dot head and the platen roller with respect to the direction of transport and guides the recording medium in a manner such that the recording medium is bent in a direction opposite to that in which the curved portion is bent.

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.
摘要:
A thermal printer has a main body, a cover body, a hinge mechanism, a first locating mechanism, and a second locating mechanism. At the time of a shift from a second state where the cover body is opened with respect to the main body to a first state where the cover body covers the main body, the first locating mechanism locates a first platen roller of the cover body with respect to a first thermal head of the main body, and arranges a second thermal head of the cover body in the vicinity of a second platen roller of the main body. The second locating mechanism locates the second thermal head arranged in the vicinity of the second platen roller by the first locating mechanism with respect to the second platen roller of the main body.

A paper discharge device and an image forming apparatus include a holding unit 101 which is rotatably mounted to a frame and is configured to hold a recording medium P discharged from an image forming unit 110 in a rolled state. The paper discharge device 100 performs a holding operation before a discharge operation. When the recording medium P is discharged, the paper discharge device 100 allows the holding unit 101 to be rotated to reach the discharge position so that the recording medium P is discharged. When the recording medium P is collected, the paper discharge device 100 allows the recording medium P to be held again within the holding unit 101, and then allows the holding unit 101 to be rotated to reach the collecting position.

A paper discharging apparatus contains a movable mechanism and a control unit. The movable mechanism moves a surface part between a first position that the surface part is not contacted with a pinch roller and a second position that the surface part is contacted with the pinch roller through a paper so as to push the pinch roller; the control unit moves the surface part to the second position, clamps the paper by the pinch roller and the surface part, and conveys the paper, thereby bending the paper, and which moves the surface part to the first position and clamps the paper by the pinch roller and a feeding roller, and rotates the feeding roller, thereby discharging the paper from the conveyance path.
