摘要： A master making device includes a thermal head with heat generating elements and a platen roller. While the head and platen roller convey a thermosensitive medium in a subscanning direction perpendicular to a main scanning direction, the heat generating elements selectively generate heat in order to perforate the medium in accordance with an image signal. The head includes a stepped portion formed at a medium outlet side in the subscanning direction. The edges of the heat generating elements adjoining the medium outside side are located at a distance of 0.018 mm to 0.5 mm from the end of the stepped portion adjoining the above edges. It is not necessary to position the head with respect to an effective nip between it and the platen roller by a troublesome procedure. Further, the distance over which the perforated medium is conveyed is reduced to obviate the reduction or contraction of an image ascribable to the sticking of the medium to the head.

摘要： A sheet processing apparatus including a sheet feeder, a sheet processing device, a sheet ejection device, a purge unit, a multifeed sensor, and circuitry. The sheet feeder feeds a sheet toward a sheet conveyance passage. The sheet processing device performs a predetermined operation on the sheet. The sheet ejection device stacks the sheet when the predetermined operation has been performed. The purge unit stacks the sheet when the predetermined operation has not been performed. The multifeed sensor detects whether sheets are multifed and a number of multifed sheets. The circuitry counts a number of sheets, determines that the sheets stacked in the purge unit is full when a number of counted sheets reaches a predetermined number of sheets, and conveys the multifed sheets toward the purge unit and adds the number of counted sheets according to the number of multifed sheets, in response to detection of the multifed sheets.

摘要： A sheet separation device that conveys a two-ply sheet in a state where the one side joined is located on an upstream side or a downstream side of the two-ply sheet in a conveyance direction, separates the two-ply sheet into the two sheets, and inserts an inner sheet from a non-joined side opposite the joined side in the sheet conveyance direction so that the inner sheet is sandwiched between the two sheets overlaid with each other includes a conveying roller pair including a pair of rollers and circuitry. The conveying roller pair conveys the two-ply sheet and holds a joined portion of in the two-ply sheet at which the two sheets are joined, at a nip portion of the conveying roller pair when the inner sheet is inserted into the two-ply sheet. The circuitry contacts the inner sheet against the joined portion of the two-ply sheet to perform skew correction.

摘要： An image forming system includes an image forming apparatus and a sheet laminator. The image forming apparatus forms an image on a sheet being conveyed as an inner sheet. The sheet laminator performs a sheet laminating operation on a two-ply sheet in which the sheet conveyed from the image forming apparatus is inserted between two sheets of the two-ply sheet. The sheet laminator includes a heater and circuitry. The heater heats the two-ply sheet during the sheet laminating operation. The circuitry is to execute a control mode when a specific abnormal event occurs among a plurality of abnormal events that occurs in the image forming apparatus, where the control mode maintains heating by the heater of the sheet laminator for a predetermined time and interrupt the heating by the heater when an abnormal event other than the specific abnormal event occurs.

摘要： A stencil printer of the present invention perforates, or cuts, a thermosensitive stencil with a thermal head to thereby make a master. The stencil printer includes a stencil distinguishing device for automatically identifying the kind of the stencil or a master setting device for allowing the operator of the printer to set the kind of the stencil. An adjusting device selects, among master making conditions experimentally determined beforehand, a master making condition matching with information output from the stencil distinguishing device or the stencil setting device. The operator can easily change the master making condition in accordance with the kind of a stencil to use.

摘要： A thermal master making device and a thermal printer including the same are disclosed. A thermistor senses ambient temperature around a thermal head. A correcting device corrects the amount of heat to be generated by the thermal head, i.e., the duration of energization at least two times during a single master making operation. This configuration reduces a change in the perforation conditions of a thermosensitive medium ascribable to the heat accumulation characteristic of the head. The printer achieves high resolution, high-speed master making and space saving.
