The paper transport path 10 is disposed in the apparatus main body 1a, and the paper transport path 10 includes a transport roller 10a, a switching claw 10b, a transport guide 10c, and the like. An opening 1b is provided at the center of the apparatus main body 1a, and a take-out device 40 is disposed in the opening 1b. The take-out device 40 is provided with a caster 41. The caster 41 can be pulled out from the apparatus main body 1b.

  Further, in the take-out device 40, a tray 42 can be moved up and down by a tray lifting / lowering means 43. The sheet S2 discharged from the printer 2 is loaded on the printer side of the tray 42, and the post-processing device is placed on the post-processing device side. The booklet S1 ejected from 3 is loaded.

  The paper stacking apparatus 20 includes a discharge roller 21, a stock guide 22, a take-out passage 23, and a tray 42. The discharge roller 21 and the stock guide 22 are provided in the apparatus main body 1a. The sheet S2 discharged from the printer 2 is discharged onto the tray 42 by driving the discharge roller 21 when the switching claw 10b is switched to the sheet stacking side. At this time, the leading end of the sheet S2 hits the stock guide 22 arranged in the vertical direction and is positioned. The standby position of the tray 42 is a position close to the lower side of the discharge roller 21 and the stock guide 22, and the sheet S 2 is accumulated by descending from the standby position, and when the discharge of the sheet S 2 from the printer 2 is finished, the take-out device 40. Pull out the front. In the case of a trial print of the paper S2 or a print failure, the paper S2 is taken out from the take-out passage 23.

  When the switching claw 10b is switched to the booklet stacking side, the sheet S2 discharged from the printer 2 is guided to the transport guide 10c by driving the transport roller 10a and directed toward the upper position of the post-processing device 3. Be transported.

  The booklet stacking device 30 includes a booklet stacking storage unit 31, a booklet transport unit 32, and a discharge position switching unit 33. The booklet stacking / accommodating unit 31 is provided in the take-out device 40 and stacks and stores the booklet S1 bound and bound in the vertical direction, that is, the vertical direction. The booklet stacking / accommodating unit 31 includes a tray 42 that receives the booklet S1 to be discharged, and a tray lifting / lowering unit 43 that lowers the tray 42 every time the booklet S1 is discharged.

  The tray 42 and the tray lifting / lowering means 43 are also used for the paper stacking device 20, and the standby of the tray 42 when the booklet stacking device 30 is used from the standby position A1 of the tray 42 when the paper stacking device 20 is used. Position A2 is at a low position. When the booklet stacking apparatus 30 is used, the tray lifting / lowering means 43 is driven, and each time the booklet S1 is discharged, the tray 42 is lowered by a thickness W1 or more of the booklet S1 as shown in FIG.

  The booklet transport unit 32 includes a timing belt 32a, a drive roller 32b, a support roller 32c, and a drive unit 32d. The timing belt 32a is provided with two hooks 32e. The timing belt 32a is stretched over the driving roller 32b and the support roller 32c, and the driving belt 32b is rotated by the driving means 32d to operate the timing belt 32a. . The booklet S1 is sent out from the discharge roller 3b of the post-processing device 3 onto the timing belt 32a, the binding portion side S1a of the booklet S1 is aligned in one direction and sent by the hook 32e, and the booklet S1 is sent from the post-processing device 3 to the booklet by the timing belt 32a. It is transferred toward the loading storage unit 31.

  The discharge position switching means 33 alternately switches the position where the booklet S1 is discharged from the booklet transport means 32 to the booklet stacking storage unit 31 back and forth. As shown in FIGS. 2 and 3, the discharge position switching means 33 is a moving means for moving the booklet discharge section 33a for holding the rear end of the booklet S1 and the position of the booklet discharge section 33a by alternately switching back and forth. 33b. The booklet discharge unit 33a includes a discharge roller 33a1 and a support 33a2 that supports the discharge roller 33a1. The moving means 33b includes a stepping motor 33b1, a pinion gear 33b2 provided on the output shaft of the stepping motor 33b1, and a rack 33b3 provided on the support 33a2. When the stepping motor 33b1 is switched, the forward rotation and the reverse rotation are performed. As a result, the pinion gear 33b2 rotates in conjunction with the rotation, and the discharge roller 33a1 provided on the support 33a2 via the rack 33b3 moves forward. And switch to the reverse discharge position P2. As shown in FIG. 4, the moving means 33b moves the booklet discharge portion 33a by a distance D2 that is equal to or greater than the width D1 of the binding portion S1a of the booklet S1, and alternately displaces the binding portion side position of the booklet S1 back and forth. The booklet S1 is discharged onto the tray 42.

  Each time the booklet S1 is discharged, the tray lifting / lowering means 43 is driven, the tray 42 is lowered by a thickness W1 or more of the booklet S1, and the binding portion S1a of the booklet S1 is alternately displaced and stacked. When the booklet S1 is discharged, the take-out device 40 is pulled out.

  As described above, the binding portion side position of the booklet S1 is alternately displaced back and forth and discharged, and the binding portion S1a of the booklet S1 is alternately displaced and stacked and stored in the booklet stacking and storing unit 31. Since the thick binding portion S1a of the booklet S1 to be stacked does not overlap with the structure, the booklet S1 can be prevented from collapsing, and a large number of booklets S1 can be stacked, and the loaded booklet S1 can be removed from the apparatus main body 1a. It can be made easy to take out.

  Further, each time the booklet S1 is discharged, the tray 42 that receives the discharged booklet S1 is lowered, so that many booklets S1 can be stacked. In particular, when the tray 42 is lowered by a thickness W1 or more of the booklet S1, the tray 42 can be lowered and stacked, and many booklets S1 can be stacked.

  Further, the booklet discharge portion 33a is alternately moved back and forth to move the booklet S1 so that the binding portions S1a of the booklet S1 do not overlap with each other and prevent the booklet S1 from collapsing. . Further, the booklet S1 can be stacked so that the closed portion S1a of the booklet S1 does not overlap by moving and discharging and stacking by moving a distance D2 greater than the width D1 of the binding portion S1a of the booklet S1. .

The present invention, for example, binding at the post-processing apparatus of the bookbinding machine or a copier, a printer, applicable to bookbinding system for stacking the discharged booklets, a simple structure, to allow the loading of many booklets And can be easily removed from the device
