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.

An AC voltage from a power generating circuit is applied to a charge roller. CPU controls the power generating circuit so as to flow a constant current according to a control value through a current path from the power generating circuit to the charge roller. CPU produces an information according to an peak value of the AC voltage applied to the charge roller. CPU produces an information according to the AC voltage applied to the charge roller when the AC voltage is in a predetermined phase.

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.
摘要:
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.

The image heating apparatus for heating an image formed on a recording material includes a heater having a substrate and first and second heat generating resistors, most of the region of said first heat generating resistor having smaller resistance value per unit length toward an end in the longitudinal direction of said substrate, and most of the region of said second heat generating resistor having larger resistance value per unit length toward the end part; wherein a safety element can control electrical power supply to said first heat generating resistor and electrical power supply to said second heat generating resistor individually, and operates in response to the heat of said heater to cut off electrical power supply to said first and second heat generating resistors; and wherein only said second heat generating resistor in said first and second heat generating resistors has a high resistance part high resistance part corresponding to said safety element in a part in the longitudinal direction thereof; and consequently, this can provide an image heating apparatus that can cut off electrical power supply quickly when a heater has run away and to provide a heater to be used in this apparatus.
摘要:
An image forming apparatus includes an image bearing member and a charge member contacted to the image bearing member for electrically charging the image bearing member. An oscillating voltage including an AC voltage component is applied to the charge member. A first detector detects an AC current applied to the charge member and a second detector detects the AC current corresponding to a peak or a neighborhood of the peak of the AC voltage. A controller effects control such that current detected by the second detector is a predetermined level when the current detected by the first detector is within a predetermined range, and such that current detected by the first detector is a predetermined level when the current detected by the first detector is outside the predetermined range.
