Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention can be used in combination with a recording device such as an electrophotographic copying device,
The present invention relates to an improvement of a recording paper sorting device that sorts the discharged recording paper.

[Background of the invention]

When creating conference materials, distribution materials, etc. from materials recorded by a recording device such as a copying device, it is necessary to align, fold, punch, or bind the materials after recording, and each set of recorded materials must be It is used and stored by binding it with staples and binding it in a file.

Therefore, in a recording paper processing device used in conjunction with a recording device, it is desirable that the plurality of sets of recording paper be differentiated for each set.

In recording devices such as electrophotographic copying machines, in addition to increasing the copying speed, a sorter device is used that aligns, T-matches, and sorts a large number of recording sheets that are ejected after copying a large number of originals. It became so. There are three types of general sorter devices: (1) a fixed bin system, (2) a system that moves all bins, and a system that moves the opening every 3N bins by discharging copies into bins (tlll) that store copies. There is one.

All of these sorter devices are large in size and have complicated mechanisms.

On the other hand, in order to distinguish between multiple sets of recording paper, the recording paper mounting surface on which the ejected recording paper is stacked and placed is moved up and down and left and right in the recording paper traveling direction. There is a paper output tray (shift tray) that is equipped with such a paper output tray.In a recording paper processing device equipped with such a paper output tray, recording paper is supplied from the outside, passes through a conveyance path, and is discharged from a paper output port. The recording sheets are stacked and placed on the recording paper placement surface of a paper output tray placed opposite to the paper output outlet.A paper output roller is provided in the vicinity of the paper output outlet, and the recording paper is driven to rotate. After one set of recording paper is stacked and placed, the paper output tray moves downward, and then shifts to the left or right in the recording paper advancing direction. After this movement, the next set of recording paper to be ejected and stacked will be more likely to be stacked than the previous set of recording paper. The recording sheets are placed shifted to the right or left in the traveling direction of the recording sheets, and these sets of recording sheets are distinguished from each other.

Instead of the above-mentioned method of sheet discharging trays, there is also a recording sheet sorting device that drives a sheet discharging roller in a biased manner to switch the direction in which the recording sheets are discharged.

The above-mentioned sets of recording sheets can be easily bundled together, and each set is post-processed into a form that is easy to use and store by punching, stapling, or file binding.

[Problem to be solved by the invention]

By the way, in a recording paper processing device equipped with a movable paper ejection tray or a deflectable ejection roller as described above, there is a possibility that the recording paper being conveyed gets caught in the rotating paper ejection roller or driven roller and jams. It may occur.

In order to remove such jammed recording paper, conventionally, the recording paper was pulled out with care so as not to break the recording paper. This requires a lot of time and also requires disassembly and inspection because it is difficult to remove the broken pieces of recording paper.

In addition, when an abnormality occurs in the drive roller, driven roller, guide member, etc. of the recording paper conveyance path, when inspecting and repairing the inside, the exterior members of the sorting device must be removed and disassembled. It was difficult to work in a narrow space close to the wall of the main body of the recording device.

[Means for Solving the Problems] The present invention has been made to solve the above-mentioned problems, and is capable of easily and quickly disposing of recording paper jams and easily and reliably carrying out maintenance such as repairs and inspections. The purpose of this invention is to provide a recording paper sorting device that can perform the following tasks.

The above purpose consists of a paper ejection drive roller, a driven roller, a guide member, and a paper ejection tray that sort and stack multiple sets of recording paper, which are ejected one by one from the paper ejection section of the main body of the recording apparatus, for each set. In the recording paper sorting device, a frame body supporting the driven roller and the guide member are integrally formed, and a part of the frame body is swingable on a support shaft of the sorting device main body. This is achieved by a recording paper sorting device characterized in that the frame body is configured to be openable and closable with respect to the drive roller.

〔Example〕

The original is placed on the platen glass of the copying device 2;
When scanned and exposed by the exposure optical unit A, the original image is projected onto the photoreceptor drum of the image forming section B. Since the surface of the photoreceptor drum is uniformly charged by the charger, the projected original image forms a latent image, which is developed by the next developing device to become a visible image, which is used to scan and expose the original surface. The image is synchronously transferred onto the recording paper (transfer paper) P fed from the paper cassette of the paper feed section C by the transfer pole.

The recording paper P on which the visible image has been transferred is separated from the photoreceptor drum by a separation pole, conveyed by a conveyor belt, fixed by a fixing section, and then delivered to the outside of the copying device 2 by a paper discharge roller 21 of a paper discharge section E. is discharged to.

Although the simplest type of copying device that performs single-sided copying from a single-sided original is illustrated, the recording paper sorting device of the present invention is not limited to this type of copying device, and can also perform double-sided copying from a single-sided original, and single-sided copying from a double-sided original. Of course, it is also possible to use it in combination with a type of copying device that performs copying or double-sided copying. In order to make these exact copies, it is necessary to invert the original or invert the transfer paper, and it is necessary to use the copying device 2 or ADF.
Although the device 3 requires a stop mechanism, these mechanisms are already known and are not the gist of the present invention, so their explanation will be omitted here.
