Abstract

PURPOSE:To allow copying or printing paper to be simply sorted by each job by installing a marking assembly in such a manner that it can be shifted to the horizontal direction by an electric signal allowing the marking position to be shifted, and accordingly allowing these paper to be marked at the different position by each job when the job has been completed. CONSTITUTION:The specified edge of copying or printing paper which comes under the same job is marked by means of marking ball 11. A screw shaft 12 is rotated by an electric signal allowing a marking assembly 9 to be shifted to the horizontal direction, and accordingly allowing the marking position to be shifted when the particular job has been completed. This enables the first printing paper 1 of the next job to be marked at the edge which is different from the previous job allowing these paper to be easily sorted by each job since it is marked at the difference position by each job.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for sorting cut sheets stored in a tray for each job.

In devices such as copying machines, printers (e.g. laser printers), printing machines, etc. that have stack trays that store a large number of sheets, such as 1,000 or 2,000 sheets, after copying or printing using cut sheets, The stored paper must be sorted for each job (copying or printing of the same button content).

[Conventional technology]

Conventionally, the following methods have been used to sort the sheets after copying or printing as described above.

■ Method of side-shifting paper after printing This method applies force in a different direction to the paper for each job when storing the paper one by one in the tray, so that the paper is stored slightly shifted for each job. It is something to do.

■ Technology for side-shifting or rotating the tray As shown in Figure 7, after storing paper 1' for one job, the descending tray 8' itself is moved to the next job by slightly shifting or rotating it. This is to ensure that the sheets of paper 1" stored in the paper are stored with a slight deviation.

■ Technique for inserting sheets of paper between each job The paper is stored between each job and a piece of paper by inserting colored paper or tape to serve as a marker.

[Problem that the invention seeks to solve]

Each of the above three conventionally used methods has the following drawbacks.

In method (2), appropriate equipment is required to apply force in a different direction to each sheet of paper for each job to shift it, and since force is applied in an oblique direction to the paper, it can cause problems such as paper jams. easy to become

In method (2), since the tray itself must be shifted or rotated, the apparatus itself becomes complicated and costs increase. In particular, it is unsuitable for a stack tray like the one of the present invention.

■What is the method? In order to put colored paper or tape between each job, a supply device or tray for the paper or tape is required, as well as when storing a large amount of paper or tape, such as in a stack tray. , because only one part of the paper is separated with tape,
The drawback is that when a large amount of paper is piled up, the paper is not stored flat in the tray, and only one side of the paper bulges up high. Furthermore, when this happens, there is a disadvantage that the paper stored next to the tape tends to get caught in the tape.

[Means and actions for solving the problem] ■~■ above
In order to improve the above problems, the job classification apparatus of the present invention adds a mark to the same part of the edge of copying or printing paper in the same job, for example, by a marking ball, and when the job ends, Move the marking position and mark a different position on the paper for the next job. This allows each job to be marked at a different position, making it easy to classify jobs.

〔Example〕

An embodiment of the present invention will be explained in detail with reference to FIGS. 1 to 6.

FIG. 1 is an explanatory diagram of the structure of a stack tray in which a marking device is arranged according to an embodiment of the present invention, FIG. 2 is a side view of the stack tray of FIG. 1 viewed from the lateral direction, and FIG. FIGS. 4 and 5 are explanatory diagrams of the marking device of the invention. FIGS. 4 and 5 are explanatory diagrams showing the state in which markings are made on printed paper, and FIG. 6 is an example of a detection circuit for detecting job breaks.

In the figure, 1 is paper copied or printed on cut paper (hereinafter referred to as print paper, including the case of copying), 2 is a conveyance roller, 3 is a conveyance guide, 4 is a metal wire upper guide, 5 is a copying machine or side guides that are supported by the main body of the printer and hold down the print paper from the left and right; 6 an end stopper for stopping the transported paper; 7 a support shaft that supports this end stopper; 8 an elevator base plate of an elevator stack tray; It is supported by a vertical movement mechanism (not shown), on which the print paper 1 is stacked and stored. 9 is a marking assembly, 10 is a marking cartridge, 11 is a marking ball, and the cartridge 10
The ink inside passes through the hole in the assembly 9 and is transmitted to the marking ball 11 to mark the paper (FIG. 3). Further, 12 indicates a screw shaft that holds the marking assembly 9.

As shown in FIGS. 1 and 2, the conveyance rollers 2, which are attached in sets of two at the top and two at the bottom, are moved in the direction of arrow A by conveyance guides 3, which are also configured to sandwich the print paper from above and below. The printed paper 1 sent from the printer is guided by an upper guide 4 and left and right side guides 5, and the leading edge of the paper hits the left and right end stoppers 6, sinks downward, and is stored one by one on an elevator base plate 8.

In this way, the elevator pace plate 8 gradually descends as each print sheet is collected.

In the present invention, when the leading edge of the printing paper 1 hits the end stopper 6, the cartridge ball 11 for marking is arranged at a position of, for example, about 5 fins from the leading edge of the printing paper 1, and the marking 13 is placed there. conduct.

As shown in FIG. 3, this marking device has a structure in which the marking force is such that the ink in the totsuji 10 passes through the hole in the assembly 9, travels around the marking ball 11 at the tip, and comes out little by little to mark the paper. It has become. Therefore, if the ink runs out, the cartridge 10
You can simply pull it off and replace it.

The marking assembly 9 having such a structure is partially supported by the support shaft 7 and is separately screwed onto the screw shaft 12, so that by rotating the screw shaft 12, the marking assembly 9 can be moved in the axial direction of the shaft (that is, the leading edge of the print paper). parallel direction). For example, when moving from one job to the next, if the marking assembly 9 is moved in the direction of about 5n axis, the job classification is
A key-shaped marking as shown in Fig. 5 is made on the leading edge of the paper, and from the next print paper 1, the position of the marking 13 shifts from 13-1 to 13-2, for example, as shown in Fig. 4(b). Therefore, after copying or printing, the stags can be easily separated by section just by looking at them from the side.

The fat in Figure 4 is marking 1 on the printed paper.
3 viewed from above (from the direction of the upper guide), the markings are placed approximately 5 mm inward from the leading edge of the paper, and Fig. 4 (b) shows an example in which markings are placed from the side, that is, from the direction of the arrow in Fig. 3. Markings seen from above, markings 1
The marking corresponding to 3-1 is shown at marking 13-1 in FIG. It is shown.

Furthermore, as shown in Figure 5, a key-shaped marking 13-3 is formed at the cut edge of the job when the screw shaft is moved, and this is used as a mark when sorting the stored print paper by job. Used effectively. Since the marking 13 is within 5 marks at most, it does not affect the contents of the copy or print at all.

Further, when the screw shaft is moved in the axial direction, if the screw shaft is connected to a small motor or the like, jobs can be classified continuously without stopping paper conveyance.

For example, data is stored magnetically in laser printers, printing machines, etc.
When stored in an α device (e.g. magnetic tape), each pattern is input as data consecutively,
At the end of copying or printing the set number of sheets of each pattern, that is, when one job is finished, a job end signal indicating the end of the job is written, so the job ends as shown in Figure 6 in the data succession circuit. By providing the signal detection circuit 20, this job end signal can be detected. When the job end signal detected in this way is input to the job break marking signal generation circuit 21, this circuit generates a signal with a certain pulse width, that is, a motor connected to the switching circuit 22 at 90.
A signal with such a width as to rotate is output, the motor is rotated, and the signal is further expanded by a gear, so that the screw shaft 12 rotates by moving the marking assembly 9 by about 5 degrees, and marking starts again.

In this way job cut marking and subsequent (
Marking indicating the next job can be performed continuously without stopping paper conveyance.

Note that the job separation may be input by an operator's switch operation, thereby rotating the screw shaft 12 by a predetermined amount. Furthermore, the marking cartridge can be easily replaced as described above, so it can be easily handled with just a touch. Of course, the marking means is not limited to this marking ball type. Any suitable material can be used.

〔Effect of the invention〕

If the apparatus of the present invention is used to perform classification for each job, a simple and compact job classification apparatus can be obtained. Furthermore, since marking is only done on the edge and leading edge of the paper stored in the tray, there is no need to apply extra force to the paper, and troubles such as paper jams are less likely to occur.Additionally, separation can be done by inserting extra paper such as tape. Since the paper does not bend or twist when stacked or staggered for each job, the paper can be easily stored in the tray, and the paper will not be tilted diagonally even when stacking a large amount of paper.

Furthermore, since it is possible to separate jobs without stopping the flow of paper at all, this is particularly effective in a device that stores a large amount of prints, such as a high-speed laser printer (4911).
