Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention collects a predetermined number of printing sheets on which a plurality of basic slips are separately printed, and steps the cutting sheets for each printing section, and then cuts them. By doing so, the present invention relates to a slip processing apparatus that creates a set of binding slips consisting of the basic slips at high speed and in large quantities, and particularly to a structural improvement for improving cutting accuracy during the cutting processing step.

[Prior Art] For example, in a retail business, when a transaction occurs between a seller side and a buyer side, a method of entering a slip is generally used as a method for confirming the location and execution of the transaction. , The slip used for this is usually a copy slip of the seller side and the buyer side, and a receipt certificate slip that goes back and forth between the two sides.
In many cases, it is a binding slip including a set of basic slips of the same size and different specifications, such as a sticking slip attached to the traded item.

In addition, the binding slips are often considerably smaller than a normal paper size in a printing apparatus such as a copying machine, for example. Focusing on this point, the binding slip has been conventionally linked with the printing apparatus, Proposals have been made for so-called slip processing apparatuses that create a large number of binding slips at high speed. For example, in the slip processing device disclosed in Japanese Patent Application Laid-Open No. 57-152990 (Japanese Patent Application No. 56-39759), printing paper for each specification formed by printing a plurality of basic slips of the same specification by a printing device is sequentially printed. After accumulating, this is stepped and cut for each printing section, so that a large number of binding slips with one set of basic slips of different specifications can be created and processed in an extremely short time. It is configured. By the way, in this type of slip processing apparatus, in order to stabilize the quality of the binding slip, in order to keep all of the basic slips of the same size and finish the end faces smoothly, in particular, in the cutting accuracy in the cutting process. Although maintenance is a problem, in the above-mentioned conventional slip processing, as shown in FIG. 3, the cutting process is performed from the non-step ring end to the cutter Ct while the printing paper P stepped by the staple St is being conveyed by the switchback. It was carried out by supplying.

[Problems to be Solved by the Invention] Therefore, in the above-described conventional slip processing apparatus, the printing paper P after the step ring is cut is started from the non-step ring edge where the trimming is not sufficient. However, there is a problem that the cutting accuracy is significantly reduced.

SUMMARY OF THE INVENTION It is an object of the present invention to solve this problem and to provide a voucher processing apparatus which has a high cutting accuracy and can minimize a decrease in the voucher creation speed.

[Means for Solving Problems] According to the present invention, a specified number of print sheets on which a plurality of basic slips are printed are collected, stepped by a stepper for each print section, and the stepped ring is printed. In a slip processing device that creates a plurality of sets of binding slips composed of the basic slips by cutting the printing paper for each of the printing sections with a cutter, the first printing paper is conveyed to the stapler. From a paper transport path, a second paper transport path provided branching from the first paper transport path, and for switchback transporting the printing paper stepped by the stapler, and from the second paper transport path. A third paper feed path for advancing the print paper carried in again to the cutter, wherein the print paper is fed from the step ring end side. It is characterized in that cutting is started.

[Operation] In the present invention, the cutting of the printing paper after the step ring is always started from the side of the step ring where the trimming is reliable, and the cutting accuracy can be improved. Further, in the present invention, since the paper feed path for the stapler of the stacked sheets and the switchback path of the stacked sheets after the step ring are different, the stacked sheets are stepped and then the stacked sheets are switched back. At the stage, it is possible to start loading the next stack of sheets into the stapler, which is useful for shortening the time for creating a slip.

Embodiments Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a conceptual diagram showing an internal cross-sectional structure of a slip processing apparatus according to the present invention, which is a paper feed port 1 to which printing paper P is fed (which is connected to a paper ejection mechanism of the printing apparatus). Between the printing paper P and the paper ejection port 2 that is ejected after the binding process,
For example, there is a paper discharge / conveyance path having a substantially E-shaped cross section, and a pair of rollers which are rotatable with respect to each other are brought into pressure contact with each other along the paper conveyance path. 3a to 3g are provided. At the three-pronged portion of the paper transport path, the posture can be changed between a solid line position and a dotted line position by a driving means such as Solenoid, for changing the transport direction of the print paper P in the paper transport path. Switch gates 4a and 4b are provided. Further, along the sheet conveying path between the sheet conveying rollers 3a to 3g, a sheet accumulating roller 5 including a paddle or a foaming roll and acting for accumulating the printing sheet P, a solenoid like the switch gates 4a and 4b, and the like. Driven by the driving means of the above, the stop gate 6 for holding the paper conveyance path in the closed or open state, the stepper 7 for stepping the accumulated printing paper P, the printing paper conveyed by switching back after the stepping. A sheet detecting sensor 8 for detecting the stop position of P and a cutter 9 for cutting the stepped printing sheet P are respectively provided. The slip processing operation of the apparatus of the present invention will be described below with reference to the conceptual process diagram shown in FIG.

In the printing device connected to the right side of the slip processing device, a plurality of basic slips P ₁ , P ₂ , P ₃ , ... With different specifications are separately printed on each individual printing paper P of a predetermined size. This is conveyed from the discharge port of the device to the paper feed port 1 of the slip processing device in order of different specifications (see FIG. 2 (a)). The first printing paper P loaded in this way is
After that, the sheet is further carried into the inner part of the sheet conveying path by the sheet conveying roller 3a and the collecting roller 5, but during the carrying in, the stop gate 6 currently held so as to close the sheet conveying path causes The transportation is stopped. Here, the accumulating roller 5 is maintained in a similar rotating state thereafter, and the succeeding printing paper P that is carried in is always positioned above the printing paper P that has been previously carried in.
Are sequentially transported to the stop gate 6 to accumulate the printing paper P (FIG. 2 (b)).
reference). At this time, in the paper transport path, the press contact and drive of the paper transport roller 3b are released, and the switch gate 4a is tilted to the position shown by the dotted line. When the specified number (corresponding to the number n of basic slips of one set of different specifications) of printing paper P is completed in the stacking step, the stop gate 6 is held in a state of opening the paper transport path. At the same time, the paper carrying roller 3b is pressed into contact with the paper carrying roller 3c and starts rotating together with the paper carrying roller 3c. As a result, the accumulated specified number of printing papers P are conveyed to the step ring position of the stapler 7 through the switch gate 4a, and stepping is performed by the staple St for each printing section (Fig. 2 ( See c)). By the time this step ring is completed, the tilting of the switch gate 4a is switched to the solid line side in the figure, while the switch gate 4b is tilted to the dotted line side in the figure above. Then, when the step ring is completed, the paper carrying roller 3c is driven in the reverse direction, and the paper carrying rollers 3d and 3e are respectively rotated in the directions indicated by the arrows, so that the accumulated printing paper P is switched back. Transport is performed. That is, by this conveyance, the printing paper P is guided upward by the switch gate 4a, with the non-step ring end at the top.
Then, after being guided to the right by the switch gate 4b, the leading end (non-step ring end) of the switchback is further conveyed until it is detected by the sheet detection sensor 8. When the non-step ring end of the (stacked) printing paper P is detected by the paper detection sensor 8, the switch gate 4b is tilted to the solid line position in the figure, and the paper conveyance roller 3e is reversely driven and Rotational driving of the paper transport rollers 3f and 3g in the illustrated direction is started. As a result, the printing paper P after the step ring is switched back again by using the switch gate 4b and the paper transport roller 4f as a guide and enters the cutter 9, and the cutting for each printing section from the step ring end side is started. (See FIG. 2 (d)). After the cutting process is completed, the printing paper P is conveyed by the paper conveyance rollers 3g as a plurality of sets of binding slips in which basic slips having different specifications are bound together, and is discharged to the discharge tray 10 through the discharge port 2. (See FIG. 2 (e)).

In the above example, only the case of obtaining a large number of same-type binding slips consisting of basic slips of different specifications at high speed was described. However, depending on the printing classification method described above, a plurality of sets of basic slips of the same specifications can be obtained. It is also possible to similarly process the binding slip and the binding slip having different specifications for each set.

[Advantages of the Invention] As described above, according to the present invention, the printing paper after the step ring is supplied to the cutter from the step ring end side to be cut, so that the cutting accuracy can be remarkably improved. It is possible to stabilize the quality of created slips. In addition, since the paper feed path for the stapler of the accumulated sheets and the switchback path after the stepping of the accumulated sheets are different,
After the stacking sheet is stepped, at the stage of switching back the stacking sheet, the next stacking sheet can be started to be loaded into the stapler, which has an excellent effect of contributing to shortening of the slip preparation time.
