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.

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 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.
