Definitions

  • the present invention relates to a sheet finisher according to the preamble of claim 1 for clinching sheet materials discharged from an image forming apparatus such as a copying machine.
  • Some of copying machines or the like are equipped with a sheet finisher to automatically clinching the sheets into one or more sets of sheets, after the sheets receive images and are discharged from the main assembly of the copying apparatus.
  • the stapler used for clinching the sheets in the sheet finisher is the one which has been developed exclusively for such use, and therefore, the stapler is expensive.
  • a sheet finisher 10 is in the form of a sorter provided with an automatic stapler and is coupled with a copying machine.
  • the sorter 10a has ten sheet discharge trays 11 which are vertically stacked.
  • Each of the trays 11 has pins 12 and 12 at its lateral sides.
  • the pins 12 and 12 are engaged with a helical groove formed in a circumferential surface of each of elevating rotatable members 13 and 13. By one full-rotation of each of the elevating rotatable members 13 and 13, the trays 11 are elevated or lowered one by one.
  • a sheet is subjected to a copying operation by a copying machine (not shown) and is discharged through a discharge passage 15, provided by top and bottom guide plates 14 and 14, to one of trays 11 by the top and bottom discharging rollers 16 and 16.
  • the structure of the sorter 10a may be any of known structure, and therefore, the detailed description thereof is omitted.
  • the automatic stapler 20 in the sorter 10a clinches the sheets 21a, 21b on the tray 11a supported by the elevating rotatable members 13 and 13.
  • the automatic stapler 20 is also inclined ( Figure 1).
  • the automatic stapler 20 is disposed adjacent a lateral side at a front part of the tray 11.
  • the non-stapling position thereof is determined so as not to obstruct the sheet discharge.
  • the stapler 20 is moved to its clinching position A for clinching the sheets 21a and 21b.
  • a lateral aligning mechanism 22 Adjacent the opposite lateral side from the automatic stapler 20, there is provided a lateral aligning mechanism 22 for the sheets 21a and 21b.
  • the lateral shifting mechanism 22 is adapted for a plurality of sizes of the sheets and is effective to urge the sheets 21a and 21b to a reference wall 23 so as to align the sheets 21a and 21b to a clinching position A.
  • the lateral shifting or aligning mechanism 22 has the following structure. It comprises a rotatable shaft 24 which is rotatably supported at the top and bottom ends. Adjacent the top and bottom ends, swingable arms 25 and 25 are fixed to the rotatable shaft 24. Between the other ends of the swingable arms 25 and 25, a lateral shifting bar 26 is extended.
  • Each of the trays 11 has an arcuate opening 17 for permitting swinging movement of the lateral shifting bar 26.
  • the lateral shifting bar 26 has a vertical length sufficient to be actable on the sheets on all of the trays 11.
  • a sector gear 27 is fixed to the bottom end of the rotatable shaft 24, a sector gear 27 is fixed.
  • the sector gear 27 is operatively connected with a reversible motor 29 through a reduction gear 28.
  • the lateral shifting lever 26 swings toward the center of the tray 11 to urge the sheets 21a and 21b to the reference wall 23, thus aligning the sheets 21a and 21b.
  • the lateral shifting mechanism 22 is operated in synchronism with the operation of the automatic stapler 20, as will be described hereinbefore. However, it is operable during the sheet discharging to effect the aligning operation simultaneously with the sheet discharging.
  • the automatic stapler 20 has a clinching mechanisms 30 and a moving mechanism 31 which are juxtaposed with each other.
  • a slidable frame 33 carrying the stapler 32 bridges between the mechanisms 30 and 31.
  • the stapler 32 comprises a clincher 32a, a magazine 32b for accommodating staples and an anvil 32c.
  • the clincher 32a is urged by an unshown spring to return to a position which is a predetermined distance away from the anvil 32c.
  • the stapler 32 is the one sold in a usual market as office equipment.
  • the slidable frame 33 is small in size in a top plan view at the clinching mechanism side and is large in the moving mechanism side (Figure 3). It has a U-shaped cross-section ( Figure 4). In a back side view, the side thereof adjacent the clinching mechanism 30 is low and horizontal. It has a stapler supporting portion 34 as a bent portion. The moving mechanism side thereof is at a high level and is provided with four guiding rollers 35 at the inside ( Figure 6).
  • the stapler 32 is the one readily available in the market.
  • a rear end 32d of the stapler 32 is engaged with a mounting portion 34a of the mounting portion 34, as shown in Figure 5.
  • the front side of the stapler 32 is fixed on the mounting portion 34 by a screw 34b. Therefore, the staple 32 is detachably mounted by the screw 34b.
  • the guide rollers 35 are engaged to upper and lower surfaces 38 and 38 of a channel like rail 37 fixed on a fixed frame 36 mounted on the sorter 10a.
  • the slidable frame 33 is guided between the non-clinching position to the clinching position A and between the clinching portion A and an outside staple loading position.
  • a spring 39 is stretched between the fixed frame 36 and a slidable frame 33 to urge the slidable frame 33 to the loading position.
  • the moving mechanism 31 is effective to move the slidable frame from the non-clinching position to the clinching position A, and the spring 39 moves the moving mechanism 31 from the non-stapling position to the loading position by releasing the moving mechanism 31 therefrom.
  • a driving shaft 41 is rotatably supported and is extended out to the moving mechanism 31.
  • the driving shaft 41 rotates through one full rotation by a motor through unshown reduction gears.
  • a clinching lever 42 is disposed which has a reverse U-shape at its front side, and is rotatably supported on the fixed frame 40 by a pin 43 at its rear or base side.

  • a clinching roller 47 Adjacent the free end of the clinching lever 42, a clinching roller 47 is mounted.
  • the clinching roller 47 has a shaft 48 engaged with elongated slots 49 to permit vertical displacement of the roller 47.
  • the shaft is urged down by a strong spring 50. Therefore, when the clinching lever 42 is urged by extremely large pressure, the clinching roller 47 retracts against the spring 50, thus avoiding application of extreme pressure.
  • the front end of the mounting portion 34 for the stapler 32 is formed into a tongue 51 which abuts a stopper 52 fixed on the fixed frame 36 when the stapler 32 moves to the clinching position A, so that the stapler 32 is correctly positioned at the clinching position A.
  • a generally heart mark shaped cam 60 is fixed to an end of the driving shaft 41.
  • the upper end portion of the swingable lever 61 is swingably supported on the fixed frame 40 by a pin 62.
  • a roller 63 is rotatably supported on the swingable lever 61, and the roller 63 is contactable to the rotatable cam 60.
  • a spring 64 is engaged at one end to the fixed frame 40 and is engaged at the other end with the swingable lever 61, so that the swingable lever 61 is normally urged to the rotatable cam 60 so as to establish a normal press-contact between the roller 63 and the rotatable cam 60.
  • the bottom portion of the swingable lever 61 has an urging member 65 rotatably supported by a pin 66.
  • the urging member 65 has an abutment part 67 at its upper front side so as to be contactable to the front surface 61a of the swingable lever 61 to urge it by a spring 68.
  • the urging member 65 rotates against the spring 68 when the slidable frame 33 is extremely urged in the sliding direction.
  • a contacting lever 69 At the top surface of the bottom portion of the slidable frame 33, there is a contacting lever 69 at such a position as to face the above-described urging member 65.
  • the middle portion of the contacting lever 69 is rotatably supported by a pin 71 on a supporting member 70 fixed on the top surface of the bottom portion of the slidable frame 33.
  • a roller 72 contactable to the urging member 65 is rotatably supported.
  • the bottom surface at the front side thereof is contacted to the stopper 73 extended from the supporting member 70, so that the position of contact between the roller 72 and the urging member 65 is limited, wherein the spring 74 provides the urging force.
  • the urging member 65 urges the contacting lever 69, so that the swingable frame 33 moves to the clinching position A.
  • the spring 39 urging the slidable frame 33 retracts the swingable frame 33 to the retracted position.
  • the contacting lever 69 has a rotatably mounted releasing roller 75.
