A stamp unit capable of opening an ink pack position between a grip member and a holder member for supplying ink to the stamp material easily in one step. To supply ink to the stamp material, the grip member is pressed downwardly with the ink pack located in the holder member. The ink pack in the holder member is pressed between a thick paper plate and a cutting rib to be opened. Ink from an ink pack flows downwardly through ink holes to be supplied to the stamp material. When the ink runs low, it can be replenished by the simple process of replacing the ink pack.

The disclosure provides a roll sheet holder for producing labels which can be easily put on a slim stick-type member used in foods without being wound on and adhered to the stick-type member, and be completely removed from the stick-type member. The roll sheet is made of a continuous thermal sheet having self-coloring property having no adhesive layer on its back side, and the like, and wound on a roll sheet holder with a back face facing outward. A plurality of encoder marks are provided on an edge of the back face of the roll sheet in a width direction, with predetermined pitch size in a feeding direction. The predetermined pitch size of the encoder marks is arranged to be equal to a length between cutting lines along which the printed roll sheet is cut. Behind the encoder marks in the feeding direction, a dog-leg shaped slits, projecting backward in the feeding direction are made in each substantially center between the cutting lines.

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 comprises a holder 4 which is to be set in a holder storage part 70 of a stamp manufacturing device for making a stamping surface on a stamp material 3 held in the holder 4. When the holder 4 is set in the storage part 70, the cam effect is generated between the positioning projection 77 of a fixing member 71 and a slant recess 43 of the holder 4, thereby positioning the holder 4 to a predetermined stamp making position in the storage part 70. In a state where the holder 4 is positioned in place, microswitches 75A and others disposed near the projection 77 of the storage part 70 are selectively turned on and off by cooperation between detection recesses 44 and a peripheral wall 38 of the holder 4, so that the existence and the type (size) of the holder 4 are detected.

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.

A fixing apparatus that conveys a printing medium to a fixing nip portion formed by rotating members, and fixes an image onto the printing medium by heat from heating elements. The fixing apparatus also includes a safety element, a rotation detection circuit, and a limiting circuit. The safety element is in a power supply path to supply electrical power to the heating elements and to shut off the path in response with an abnormal temperature. The rotation detection circuit detects a rotation state of the rotating members. The limiting circuit limits a drive of a second driving circuit per a rotation detection circuit output. A first driving circuit detects that the circuit drives a first heating element per a control signal, regardless of the rotating members rotation state, and the second driving circuit drives a second heating element per a control signal and the output from the rotation detection circuit.
