摘要:
A recording device presses a thermal head, where heating elements are arranged in a direction orthogonal to a transport direction of the print medium, against a printing surface of the print medium at a printing portion on a transport path of a print medium transported by a transport means, controls the flow of current selectively applied to the heating elements, and performs desired printing at a printing area on the printing surface. The print medium has a shape having portions where the contact lengths of the printing surface coming in contact with the heating elements in a width direction orthogonal to a transport direction of the print medium are different in the transport direction. A pressing load of the thermal head is frequently adjusted according to the contact length of the printing surface of the print medium.

A sheet feed mechanism is provided. In a sheet feed mechanism, a first sheet feeding device includes a first sheet feed roller and a first pressure contact roller that can be in pressure contact with the first sheet feed roller. The sheet feed mechanism further includes a recording sheet, which can be conveyed downstream by the rotation of the first sheet feed roller while being held in pressure contact between the first sheet feed roller and the first pressure contact roller. The first pressure contact roller is connected to a pressure contact release mechanism that can release the pressure contact of the first pressure contact roller with the first sheet feed roller. The pressure contact release mechanism is provided near the center in an axial direction of the first pressure contact roller.

A heat transfer printer includes a line thermal head having heat generating elements formed in a straight line at one end of a top surface of a substrate and a sealing member for covering and protecting at least a portion of the top surface of the substrate at the other end thereof opposite to the heat generating elements. A film wrinkle removing member is disposed in the vicinity of the heat generating elements of the line thermal head upstream in a direction that an ink film is carried. A voltage is selectively applied to the heat generating elements when the line thermal head abuts a platen with the ink film and a printing sheet sequentially overlapped from the line thermal head disposed therebetween.

A thermal transfer printer includes a thermal head, a platen roller which allows the thermal head to be in the head up/down state, an ink ribbon which is drawn between the thermal head and the platen roller, a paper feed roller which can convey a recording paper. A peeling member is disposed on the downstream side of the thermal head in a conveyance direction of the recording paper and can peel the ink ribbon adhered onto the recording paper during printing, and an optical ribbon detecting sensor, which can detect a color discernment marker corresponding to an ink surface of a desired color formed on the surface of the ink ribbon, is disposed between the thermal head and the peeling member.

A paper feed mechanism is provided. The paper feed mechanism includes a pair of paper feed rollers at the upstream side and the downstream side of a printing device in a direction in which a recording paper is fed during printing, and press contact rollers in press contact therewith. The back surface of the recording paper receives a pushing force from projections formed on the pair of paper feed rollers by a predetermined depth such that the recording paper is fed during printing by the printing device.
