Abstract: A heater for a fixing device heats an object to be heated, the object traveling in a first direction. The heater includes a substrate facing the object and extending in a second direction orthogonal to the first direction; a heating body extending on the substrate in the second direction; a first conductor and a second conductor disposed on the substrate to supply power to the heating body; a plurality of first electrodes each connected to the first conductor and configured to supply power to the heating body; and a plurality of second electrodes having a polarity different from that of the first electrodes, each connected to the second conductor, and configured to supply power to the heating body. The first electrodes and the second electrodes are configured to intersect the heating body, alternately arranged in the second direction, and inclined with respect to the first direction.

Abstract: A heater for fixing devices includes a glass substrate, a heating element, electrode patterns connected to the heating element, a first protective layer, and a second protective layer. The glass substrate is made of an alkali-free glass. The first protective layer is formed by firing a mixture of a first glass powder and a first filler. The first glass powder contains no alkali metal oxide and has a lower softening point than the glass substrate. The first filler has a lower thermal expansion coefficient than the alkali-free glass for the glass substrate. The second protective layer is made of a material that does not contain the first filler contained in the first protective layer.

Abstract: A recording apparatus including a printing unit that contacts or separates a thermal head with or from a platen using the driving force of a UD motor, one or more sheet feed units that include sheet feed rollers which are rotated forward or backward by the driving force of an LF motor transmitted through a transport gear group and pressure rollers which are supported between a pair of roller supporting members and are urged by elastic members to come into pressure contact with the sheet feed rollers, and are provided on an upstream side and a downstream side of the printing unit in a transport path of a recording sheet, a pressure release mechanism including a cam shaft that is rotatably provided so as to tilt the pair of roller supporting members of the sheet feed units against the urging force of the elastic members and separates the pressure rollers from the sheet feed rollers, and a pressure release gear group that transmits the driving force of the LF motor to the cam shaft of the pressure release mechan

Abstract: 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.

Abstract: Disclosed is a disk label printer that includes a slot-in type optical disk driving mechanism and a printing mechanism integrated with each other, has a small size, and smoothly transfers optical disks. The disclosed disk label printer includes: a case that has a slot through which an optical disk is inserted or ejected formed therein; an optical disk driving mechanism that is provided in the case and writes and/or reads signals to and/or from the optical disk mounted to a disk mounting portion; and a printing mechanism that is provided in the case and includes a thermal head which prints a desired image on a label surface of the optical disk. The printing mechanism is provided on a transfer path of the optical disk toward the optical disk driving mechanism between the slot and the optical disk driving mechanism.

Abstract: An ink ribbon assembly for use in a thermal transfer printer includes a plurality of ink ribbons 17a, 17b and 17c which has at least one ink ribbon 17c less influence on an outcome the printing accuracy is shorter in length than the other ink ribbons 17a and 17b. The shorter ink ribbon has a terminal end mark 60 formed at its terminal end. At the time point when the end of the shorter ink ribbon is detected in the middle of the printing of one printing area, the other ink ribbons have finished the printing of such printing area, because they are longer than the ink ribbon 17c, and thus, joints cannot be produced in the printing with the longer ink ribbons.
