Abstract: The present invention provides a plate material made only of thermoplastic resin film by use of a polyester film so that an ink-penetrating opening can be thermally perforated without increasing the output of a thermal head. The film is a heat sensitive stencil plate material 12 for stencil printing having a predetermined thickness, and is composed of an extended PET film or a extended low melting temperature film produced by copolymerizing PET and PBT. Many minute recesses 14 are formed on one side of the film by templating. The templating can be carried out at a working pressure of 104×102(m-t)/(m-g) Pa or more, when the working temperature is t° C.; the melting point of the film is m(° C.) and the glass transition point of the film is g(° C.).

Abstract: The present invention relates to an adhesive coating device for sheet-binding provided with a roller 14, part of which is immersed in adhesive 10 stored in an adhesive reservoir 12, for applying hot-melted adhesive 10 in the above-mentioned adhesive reservoir 12 along the arranged one-side edge of a bundle of sheets 54 while rotating. The device includes an electromagnetic induction heating coil 20 disposed in the vicinity of the above-mentioned roller 14, and a current supply device 51 for supplying a high-frequency current to the above-mentioned electromagnetic induction heating coil 20.

Abstract: A sheet processing apparatus for punching a sheet having a detachable punching unit for accomplishing wide varieties of combinations of punching conditions such as a number of the hole, diameter of the hole, and a position of the hole at a sheet. A sort of the punching unit which is mounted to the apparatus is recognized by a recognition device and one of a sheet conveying speed, a punching speed, and a punch operation timing is controlled by a controller in accordance with a condition predetermined for each sort of the punching unit which is recognized by the recognition device.

Abstract: A clamping device for clamping sheets stacked on a bin of a sorter is composed of a moving unit, on which clamp levers are mounted, and an unshakable unit, on which an opening and closing mechanism for the clamp levers and a moving mechanism for moving the moving unit in the state of keeping the clamping of the sheets, are mounted. Thereby, a solenoid for opening or closing the clamp levers mounted on the moving unit and a wire harness connecting electrical device mounted on the moving device with a connector mounted on the unshakable unit are omitted.

Abstract: A sheet sorting and storing apparatus has a stack of bin trays which are brought open at a sheet reception position, but held close at the other position. The apparatus minimizes noises upon sheet reception with a simple mechanism, improving the efficiency of sheet sorting. The bin trays are inclined down or up depending on a position of a sheet discharge device. A desired bin tray is deviated by a deviation mechanism in an approximately horizontal direction so that a spacing in the direction of the tray inclination is enlarged between two adjacent bin trays located at the sheet reception position, while keeping constant a vertical spacing thereof. A flexible film of elastic material may be provided at the sheet entrance side of the bin trays to prevent the discharged sheet from leaping out thereof.

Abstract: A finisher for an image forming apparatus and capable of changing the binding angle of a staple relative to a sheet stack to be bound, as desired. A stapler is rotatable substantially about the binding position thereof to change the angle thereof relative to a sheet stack. This maintains the binding position substantially constant in both of parallel binding and inclined binding.

Abstract: A finisher for positioning stacks of paper sheets each being loaded on individual bins of a sorter and stapling the positioned stacks by a stapler one at a time. The finisher has a paper pulling device for pulling a stack of paper sheets to a stapling position of the stapler. The paper pulling device has an upper and a lower chuck which cooperate to grip the stack of paper sheets at a plurality of points of the latter. The upper and lower chucks are mounted on the free ends of an upper and a lower rotatable lever, respectively.

Abstract: A paper handing apparatus having a plurality of bins, a chuck unit and a stapler unit movable up and down along the bins, and a sorting unit. The sorting unit distributes a number of paper sheets received from a copier or similar image forming apparatus to the bins, while the stapler unit binds an end portion of each of the stacks of paper sheets loaded in the individual bins. The stapler is movable between and lockable at a position for binding a paper stack and a position for supplying staples. The stapler unit is removable from the sorting unit. Doors such as a stapler door are provided on the housing of the apparatus. When a door other than the stapler door is opened when the stapler is performing a stapling operation, the stapling operation is continued until it completes.

Abstract: A finisher having a stapler for stapling paper sheets sequentially discharged onto a two-sided copy tray of a copier, facsimile machine, printer or similar equipment or onto a bin of a sorter. A paper positioning device included in the finisher has a bin fence and a positioning member. The bin fence is provided on each bin and extends along one side edge of the bin. A positioning member is reciprocatingly movable from a standby position thereof toward the bin fence and back to the standby position. During such a reciprocating motion, the positioning member is repetitively brought into and out of contact with a stack of paper sheets to thereby position the stack. The moving speed of the positioning member is variable.

Abstract: A paper positioning device having a paper positioning member which is pivotable in abutment against one edge of a paper sheet loaded on a receptacle for moving the paper sheet to a positioning position for thereby positioning the paper sheet. By a simple mechanism and control, the movement of the paper positioning member is slowed down at the positioning position and accelerated until the positioning member reachines it. The paper positioning member performs a pivoting movement twice while a drive shaft associated therewith performs a reciprocating movement once. The device is, therefore, no only durable but also positions paper sheets efficiently and positively without damaging the paper sheets.

Abstract: A paper handling apparatus having a plurality of bins and a chuck unit and a stapler which are movable along the bins and causing the stapler to bind an end portion of a stack of paper sheets which have been received from a copier or similar image forming apparatus, sorted, and then loaded on any one of the bins. The chuck unit has an upper and a lower chuck. After the stapler has bound a stack of paper sheets a push bar independent of the chucks of the chuck unit pushes the end of the stack to return it into the bin. Both the upper and lower chucks are movable up and down. The force which the chucks exert on a stack of paper sheets is controlled in matching relation to the thickness of the stack.

Abstract: An illegal-sheet-material detecting apparatus, which is adapted to detect whether the property of each of the passing sheet materials is legal or not in a sheet manufacturing machine, provided with a comparison circuit for detecting the lag of the same detection value of the n th+ first sheet material with respect to the detection value showing the property such as thickness, size or the like of the optional portion of the n th sheet material memorized in the memory circuit as an electric signal. When the lag detected by the comparison circuit has exceeded a predetermined range, the counting operation of the sheet material is caused to stop thereby to use the detection value of the n th sheet material as a reference value for comparing it with the n th+ first sheet detection value.
