The stamp material has a front surface projected form the end of the holder member and a circumference portion. The front surface includes an effective stamp surface that includes a stamping portion and a non-stamping portion. The circumference portion is defined at least by an area existing between positions corresponding to the end of the holder member and the effective stamp surface, within an exposed area of the stamp material from the holder member, the area being entirely covered by a sealant.

Abstract: A stamp unit 1 is formed so that the circumference of the stamp material 3 is made as a slant surface 83 by heat-pressing both the lower end 4a of the holder 4 and the circumference of the stamp material 3. The lower end 4a of the holder 4 is formed in a wedge 82 so as to hook the circumference of the stamp material 3. Thereby the stamp material 3 can be surely retained to the holder 4, and the stamp material 3 and the holder 4 can be firmly sealed. As a result, stamping durability is remarkably improved when many stamping operations are repeated.

Abstract: A method for manufacturing a pattern sheet for plate-making capable of easily forming a positive image through the use of a photographic negative film. In this method, as a first step, a negative film with a printed negative image is placed on a surface of a light transmission sheet carrying a photosensitive color-developing layer containing a photosensitive color-developing material which makes a color development in response to light. Further, as a second step, the light is applied thereto from the negative film side after the first step. As a result of the application of the light, a color development takes place in the photosensitive color-developing layer due to the light passing through the negative image, thus causing a positive image to be formed on the surface of the light transmission sheet.

Abstract: A stamp unit has a transparent film which protects a stamp surface of the stamp material at the time of transportation of the stamp unit, during storage until a user starts to produce a stamp after purchasing the stamp unit, and during production of the stamp plate. The transparent film is thermally adhered on the lower edge of the holder member and is capable of protecting the surface of the stamp material until the start of the stamp printing. The transparent film is capable of easily and economically adhering to the stamp material without adhering to a thermal adhesion jig.

Abstract: A stamp unit includes a grip portion to be grasped by a hand, a stamp portion that is fixedly linked to the grip portion, a skirt member covering the outer peripheral side of the stamp side, and a protection cap that is freely detachably mounted on the stamp portion. The skirt member is upwardly and downwardly slidably supported. At its nonuse time, the lower end of the skirt member projects to a position lower than a print face portion of the stamp portion. However, by locating the stamp unit at a print position and pressing the grip portion, the skirt member is moved upwardly, and the print face portion of the stamp member is pressed against a print surface, whereby ink oozes out from the print face portion to perform the print operation. The stamp unit is further provided with plural engaging holes formed at the lower portion of the grip member and plural engaging pawls that are provided at the upper portion of the stamp member and elastically engaged with the respective engaging holes.

Abstract: A stamp apparatus prevents a used stencil plate from being used again for making a plate. The apparatus includes a reflective photo sensor that determines if thermal paper of the currently set stencil plate is colored from a past plate-making process. On detecting the colored thermal paper, the sensor prompts an LCD to give an alarm display warning the user of the used stencil plate. Alternatively, a retractable projection interferes with insertion of a used stencil plate. In both cases, the stamp apparatus remains disabled until the used stencil plate is removed. This protects the stamp apparatus from getting soiled or damaged by spilled ink from the used stencil plate set inadvertently by the user.

Abstract: A stencil plate having a heat sensitive stencil paper sheet formed of a thermoplastic film and a porous support member, a non-woven fabric impregnated with ink, a frame member disposed so as to surround the non-woven fabric, an ink-impermeable film, and a peelable surface film having a high temperature heat resisting property that is superior to the thermoplastic film. The surface film may be a peelable member or there may be a peelable member adhered to the surface film so as to peel both, the peelable member having a projecting portion. When the projecting portion which projects from a frame member, is gripped and pulled, the surface film on a stenciled face, is gradually peeled away and removed from the stenciled face so that a heat sensitive stencil paper sheet in the stenciled condition is exposed.

Abstract: To form a good perforation image and prevent oozing of the ink in the processing of plate making, a heat sensitive stencil 10 is generally made of a heat sensitive film 12, a non-woven fabric 16 impregnated with ink, a separator 14, a frame 18 located so as to surround the non-woven fabric 16, and a film 20 as a base having an ink impermeability. The separator 14 is located between the heat sensitive film 12 and the non-woven fabric 16. An end portion of the separator 14 is inserted through a slit 18c of the frame 18, and extends through between the frame 18 and the film 20 to the outside of the heat sensitive stencil 10.
