摘要: A sheet laminator including a thermal pressure roller, a power cutoff device, a mover, a power line, and circuitry. The thermal pressure roller pair includes first and second rollers, and first and second heaters, to form a nip region to press and convey a two-ply sheet. The power cutoff device detects a change in temperature of at least one of the first or second roller, and cuts off a power to at least one of the first or second heater. The mover relatively moves the second roller away from the first roller. The power line couples the power cutoff device to the mover. The circuitry is to cause the power cutoff device to cut off the power line, and cause the mover to relatively move the second roller away from the first roller, in response to the power cutoff to at least one of the first or second heater.

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 sheet processing device includes a sheet storage and a sheet displacer. The sheet storage includes a first storage portion that includes a first wall that is one side wall of the sheet storage and a second wall that is part of another side wall of the sheet storage and a second storage portion that includes a third wall continuous to the first wall and the second wall. The sheet displacer displaces a preceding sheet stored in the sheet storage and contacts an upper end of the preceding sheet to displace the preceding sheet such that the upper end of the preceding sheet moves toward the third wall. The second wall and the third wall are coupled via a bent portion that bends in a manner such that a storage space of the second storage portion is greater than a storage space of the first storage portion.

摘要: A thermal master making device includes a thermal head having a plurality of heating elements arranged in an array in the main scanning direction. The thermal head is caused to contact a stencil including a thermoplastic resin film. While the master is fed at a preselected feed pitch in the subscanning direction perpendicular to the main scanning direction, the heating elements selectively heat and perforate the film of the stencil in accordance with image data to thereby form an image in the stencil in the form of a dot pattern. A pitch at which the heating elements are arranged and the feed pitch are substantially equal to each other. The heating elements each have a length in the subscanning direction smaller than one-half of the feed pitch inclusive and have a length in the main scanning direction greater than the length in the subscanning direction. The device is capable of stably forming desired perforations in the stencil and extending the life of the heating element and therefore the life of the head. In addition, the device needs a minimum of master making time and therefore operates at a high speed.

摘要: A thermal master making device and a thermal recording device each including a thermal head and a platen roller. The master making device thermally perforates, or cuts, a thermosensitive stencil for making a master while the recording device thermally records an image on a thermosensitive recording medium. The devices each reduce the corrosion of an expensive thermal head in any environmental conditions while guaranteeing the conveyance of the stencil or the recording medium. The stencil and recording medium each contain a corrosive substance in an antistatic agent or adhesive or an overcoat layer thereof. The corrosion of the head would directly translate into defective images. With the above devices, it is possible to reduce a burden on the user and to extend the life of the head. Extending the life of the head is desirable from the environmental standpoint also.

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 sheet processing apparatus including a sheet feeder, a sheet processing device, a sheet ejection device, a purge unit, a multifeed sensor, a sheet sensor, and circuitry. The circuitry stops an operation of the sheet processing apparatus when the multifeed sensor has not detected multifeed of the sheet and the sheet sensor does not detect a trailing end of the sheet after a first set time from detection of a leading end of the sheet, stop the operation when the multifeed sensor has detected the multifeed and the sheet sensor does not detect the trailing end of the sheet after a second set time from the detection, and conveys the sheet toward the purge unit without stopping the operation when the multifeed sensor has detected the multifeed and the sheet sensor detects the trailing end of the sheet before the second set time elapses from the detection.

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.
