Abstract

PURPOSE:To discriminate in same carrying path by arranging a plurality of stopper members having lower frictional force against a rotary member having high frictional force while slidably in a path for member to be matched with a pin. CONSTITUTION:Upon jamming of paper between a roller 36 and a bottle, the papers P1-P3 completed of printing at this moment are stored sequentially on a stopped roller 25 in the carry path 22. Under this state, the jammed paper is removed to output the removed print as a paper P4 for the purpose of page matching. Upon rotation of roller 25 having higher frictional force than those of stopper members 26, 28 to the right, the paper P4 is fed through the frictional force of roller 25 while upon rotation of roller 25 reversely, the papers P1, P2 and P3 are fed in this order from between the stopper member 28 and contained sequentially in bottles.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for collating prints output from an electronic billinter or the like. %, when performing selective collation, if a print that is to be collated jams and is removed, subsequent sheets that have already been printed are stored on the jammed sheet to remove the jam. After removing the print, the same page is printed again, and after collating, the stored pages are sequentially set to a predetermined number.

This is a device that distinguishes between prints that are being stored on the same conveyance path and prints that make up for a jam when the sheets are stored in a stack. Is it a traditional style? ′? (hereinafter referred to as a sorter), in the case of a jam occurring in the sorter, the subsequent paper is temporarily inserted into the second conveyance path which is a temporary bypass, and the printer chain 11 is cut off in a timely manner. After processing p↓ and energizing? After the new compensation prints from the T printer are conveyed through the normal conveyance path and collated, the prints are conveyed from the second conveyance path to the first conveyance path by switching and collated sequentially. In particular, the present invention provides a paper discriminating device that does not have a plurality of conveyance paths (or has functions equivalent to or more than the above-mentioned plurality of conveyance paths). It is possible to realize miniaturization by eliminating the need for printers, supporting high-speed printing, etc. This will be described below with reference to the drawings.

A diagonally downward guide plate 18 and an opposing guide member 19 are placed on the discharge side of the roller 14, and when sheets are stored below the guide member 19, a guide plate 18 is placed at the rear end of a predetermined sheet. Therefore, in order to avoid assembling the next paper, the trailing edge of the paper has two steps.
A guide plate 21 having a step 20 that is sunk within 0 is disposed opposite to the guide plate 18 to form a conveyance path 22. Furthermore, a guide section 23 consisting of a pair of opposing members forming a transport path 2 is disposed above the discriminator 24 and serves to guide the paper to the discriminator. As shown in FIG. 3, the discrimination device w24 is supported by support members 27 and 29 to which locking members 26 and 28 made of foamed urethane or the like having a slightly low coefficient of friction are attached, and as shown in the figure, the friction 'fk-number The support members 27 and 29, which are made of a highly elastic material such as rubber and are pressed from two directions with the roller 25 in between, are supported at rotatable support points 229', 7' and -1. The pressure welding is urged by spring members 3o and 32 whose one ends are fixed to 31 and 33, respectively. The roller 25 can freely rotate forward and backward, and the direction of rotation is related to the discrimination of paper. A flat conveyance section 35 is formed below the discriminator 24 and is used to convey sheets for collating each toe. At the bottom of the discriminator 24, opposing guide members 34 are disposed, and a pair of rollers 36 and a pair of vertical guide plates 37 are provided. The insertion device corresponding to ≠738 is the roller 38a group and the roller 38b group or each shaft 38
and 38// and are in pressure contact with each other, and by applying rotation, the paper is sandwiched. As shown in FIG. 2, when the solenoid 38s is energized, the guide pawl 38c operates the plunger 38s' to align and fix the shaft 38d via the link mechanism 38s''.

Furthermore, light-emitting elements 44, 46 and 48, which are provided with optical sensors for detecting the passage of paper, are located on the delivery side of the transport roller 14, the delivery side of the roller 36, and the pin insertion side, respectively. They are light receiving elements 45, 47 and 49. Of course, the paper p sent out from the printer 1 mentioned above is conveyed through the conveyance path 17, and as shown in the enlarged detailed side view of FIG. For storage, solenoid 3
8S, the pusher 38s operates, rotates the shaft 38d via the link mechanism, and rotates the guide pawl 38c.
Rotate to the solid line position and remove the roller 38a group and guide claw 38c.
Insert it into the bottle 38 in the direction of arrow F. At this time, the paper p is received by the sorter 11 and transported through the transport path 17, but when the trailing edge of the paper p passes the fixing device 9,
The paper p is accelerated, and the speed inside the machine is about 2 to 5 times that in the printer 1. The paper IP transported in the transport path 17 further falls into the transport path 22, as shown in FIG. The paper p passes between the light-emitting element 44 and the light-receiving element that form the optical sensor, and the paper p passes between the light-emitting element 44 and the light-receiving element, whose tip is on the roller 25 and blocks light. rotate in the direction. The paper p is as shown in FIG.

The paper p is conveyed, and the paper p is moved by the movement of the guide claw 38c as described above.
The insertion of the sheet P is completed, but the solenoid 38s is energized at the same time as the light from the light emitting element 46 is blocked, and as soon as the light path 50 of the paper p being inserted is finished blocking, the solenoid 38s is cut off.
The guide claws 38C are originally 12, and 0 or more forming the conveyance path for the next-order paper are platforms on which the paper p is stored in the bin 38 within a predetermined set time. Next, a case will be described in which the paper p is jammed between the roller 36 and the bin 38. At the time when the jam occurs, the cassette 5 of the laser beam printer I, the conveyance path 7, and the conveyance path 17 of the sorter If there are three sheets of paper in order of priority, or if the paper has already been fed and the fourth sheet is stopped at the jam check signal, as shown in Figure 5, printing will be performed. The sheets p1 to p3 are stored in the conveyance path 22. In this state, to remove the jammed paper and match the collated pages, print the removed paper anew and print it again. As shown in FIG.
Due to its structure, sequentially printed sheets can be placed on top of the stored sheets. Therefore, as shown in FIG.
is output last in the conveyance path 22, but paper p4
are first inserted from the conveyance path 22, and then the sheets pi p2 and p3 are extracted in the order of collation. Therefore, by rotating the roller 25 in the direction of the arrow, as shown in FIG. It is locked. The light from the light emitting element 46 is transmitted to the paper p.
When the tip of the paper p4 is pinched by the roller 36 due to a change in the light receiving element 47, the already energized electromagnetic clutch (not shown) is de-energized, the electromagnetic brake is energized, and the roller 25 is stopped. Then, the paper p4 is removed by the roller 36.
is extracted from the discriminator 24. Therefore, as shown in FIG. 7, sheets p1 to p3 remain in the discriminator 24. When the paper p4 is stored in the bin 38, the current of the solenoid 38s is cut off and the guide claw 38c returns to its original state, so that the papers p1 to p3 are sequentially extracted and inserted into the designated bin.

In this case, as shown in FIG. 7, the roller 25 is rotated counterclockwise in the direction of the arrow, and as shown in FIG. When the roller 25 is fed, the roller 25 stops and the roller 3
At step 6, the paper p1 is pulled out from the discriminator 24. By repeating the above operations, sheets p2 and p3 can be sequentially extracted. If the collection of the stored amount is completed in 0 or more operations, normal operation can be started. By considering the outer diameter of the roller 25 and the shape of the locking member, the device 24 can extract a predetermined amount of paper even if the storage capacity increases. In addition, depending on the rotation direction of the rotary sheet, selective extraction of the stored paper can be easily performed.

The roller 25 is divided into a high friction part 25 and a low friction part 25 as shown in FIG. Then, when the paper is pulled out as shown in FIGS. 6 and 8, the friction image anti-load at the time of pulling out becomes lighter. Also the first
