The disclosed invention is a stamp unit that includes a holder member having an end. A stamp material is made of a porous material retained by the holder member. 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.

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.

A stamp device for a seal plate is provided, which is configured so that the seal plate is easily attachable to and detachable from a supporter of the stamp device for removal or replacement and so that the seal plate does not detach or shift from the stamp device during a stamping or marking operation. The stamp device includes a supporter having a pair of longitudinally extending engaging claws for pinching opposite longitudinally extending edge faces of the seal plate; a recessed groove stopper portion for receiving and holding one end portion of the seal plate; and a pressure sensitive weak adhesive layer provided on a seal plate supporting face of the supporter.

A stamp unit capable of preventing ink from leaking out of the stamp unit is disclosed. The stamp unit includes a skirt member attached to an ink impregnated body. The skirt member has a substrate formed with a through-hole at its center. A pair of first guides and a pair of second guides are provided on the substrate for guiding corresponding edge portions of a stencil sheet. The first guides extend in a lengthwise direction of the substrate, and the second guides extend in a widthwise direction of the substrate. A pair of third guides are provided on the substrate outside of the second guides. The third guides guide corner portions of the stencil sheet so as to position between the second guides and the third guides. The corner portions guided by the third guides have corners with sharp crease.

A roll sheet is unwound and fed with its side edge being positioned in a reference point of the thermal head, and then subjected to printing by the thermal head. Coil springs are placed at positions respectively dividing substantially equally a length from a center to each end of the thermal head. A distribution of loads on the thermal head by each coil spring is determined so that a load exerted on the thermal head on the reference point side is larger than a load exerted on the thermal head on the opposite side. A position of a resultant force of the coil springs acts on the thermal head at a position displaced by a distance obtained by multiplying an entire length of the thermal head by a coefficient, from a center of the thermal head in the longitudinal direction toward the reference point.

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.
