Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a sorter connected to an image forming apparatus such as a copying machine or a printer.

<Prior Art> For example, in a sorter connected to a copying machine and distributing and accommodating ejected copied sheets, the number of accommodating pins for accommodating sheets and the number of accommodating sheets per pin are determined.

For example, some relatively small models have 10 pins and can accommodate 30 sheets of paper per pin, while relatively large models have 20 pins.
Some pins can accommodate 50 sheets of paper per pin.

In terms of the performance of the sorter, it is preferable that both the number of accommodated pins and the number of sheets accommodated per pin be large, but this has drawbacks such as the overall shape and weight of the sorter becoming too large and the price becoming too high.

Therefore, in conventional sorters, the appropriate number of pins to accommodate and the number of sheets to accommodate per pin are determined depending on the type.

<Problems to be Solved by the Invention> Incidentally, in copying a manuscript, there are cases in which a comparatively small number of copies of a manuscript containing a large number of pages must be made. For example, there is a case where 10 copies of a 60-sheet original must be made.

In such a case, if you are working with a conventional sorter that accommodates 20 pins and 50 sheets per pin, ■: First, for example, 50 out of 60 documents are sorted as follows. Copy 10 copies using the 10-pin storage pin on the upper half, ■Secondly, copy 10 copies of the remaining 10 originals using the 10-pin storage pin on the lower half, ■: ■ and ■
This requires a three-step process in which the originals copied in 1 and 2 are combined to create 10 copies of 60 originals.

As described above, when the number of copies is small but the number of originals is large, the conventional sorter has the disadvantage that it is not easy to use.

In other words, (number of pins accommodated) x (number of sheets accommodated per pin)
-(20X50-1000) is (total number of copies) -(
Although the number of copy sheets is larger than 10 copies x 60 sheets - 600 copies, the paper has the disadvantage that it is not possible to sort the copy sheets in one operation, and the work efficiency is poor.

It is therefore an object of the present invention to provide a sorter with improved usability compared to conventional devices.

Means for Solving the Problems> The present invention provides a sorter that is connected to an image forming apparatus and has a plurality of accommodation pins for storing image-formed sheets discharged from the image forming apparatus. Among these, this sorter is characterized in that predetermined accommodation pins are removable.

Further, the sorter is characterized in that removable storage pins are arranged every other pin.

Function> The number of copies of image-formed paper to be ejected is small, but if the number of sheets per copy is large, the remaining accommodation pin 1 can be removed by removing the desired pin from among the predetermined removable accommodation pins. The number of sheets accommodated per pin can be substantially increased.

If removable storage pins are arranged every other pin,
By removing the removable accommodation pin, the accommodation capacity per remaining accommodation pin can be doubled.

<Embodiment> Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 2 is an illustrative side view showing a schematic configuration of a housing pin portion of a sorter according to an embodiment of the present invention. This sorter has 20 storage pins and can accommodate 50 sheets of paper per pin. Each accommodation pin 11-1□.

are held by trunnions 21 to 220, respectively, and the accommodation pins 11 to 120 are arranged at intervals of X from each other.

This interval X is proportional to the paper storage capacity, and in the case of the interval X, 50 sheets can be stored. Each trunnion 21-220
is guided by a guide groove (not shown) extending in the vertical direction,
It is moved up and down by a cam 3.

The paper P is discharged from a discharge roller 4 arranged near the rotation center of the cam 3. In other words, the ejection position of the paper P is always at a fixed position, and the cam 3 causes the trunnion 2. ~2□0
is moved, and when the paper P is ejected, the paper is received by one of the receiving pins 1° to 12o located at the ejection position.

One of the features of this embodiment is that the accommodation pins 1□-1□0 held by the trunnions 21-2□0 are detachable from the trunnions 21-220, respectively.

Next, referring to FIG. 1, a structure for attaching and detaching the trunnion 2 and the accommodation pin 1 will be explained.

FIG. 1(A) is a plan view of the accommodation pin 1 held by the trunnion 2, and FIG. 1(B) is a side view thereof. Moreover, FIG. 1(C) is a diagram showing the shape of the rear end portion of the accommodation pin 1 seen from the direction of arrow C in FIG. 1(B), and FIG. FIG. 2 is a diagram showing the configuration of the trunnion 2 as seen from the direction of the arrow.

Three engagement convex portions 5a, 5b, and 5c are formed at the rear end of the accommodation pin 1, and protrude intermittently.

On the other hand, the trunnion 2 includes the convex portion 5a of the accommodation pin 1,
Engagement holes 6a, 6b that can accept 5b, 5c,
6c is formed.

Therefore, the protrusions 5a, 5b, 5C at the rear end of the accommodation pin 1 are the engagement holes 6a, 6b formed in the trunnion 2.

6C, the rear end of the accommodation pin 1 is inserted into the engagement holes 6a and 5.
b, 5c and the receiving part 7 and is firmly received and held.

In order to remove the accommodation pin 1 from the trunnion 2, the accommodation pin 1 may be pulled out in the opposite direction to the arrow.

Note that outer end support members 8 are removed from both front sides of the accommodation pin 1. Further, a triangular notch 9 is formed at the tip of the accommodation pin 1 to facilitate the removal of paper stored in the accommodation pin 1.

Figure 3 shows the sorter shown in Figure 2 with one storage pin.
FIG. 6 is an illustrative side view showing a state in which the pin is removed.

In FIG. 3, accommodation pins 11 to 1□.

Odd-numbered accommodation pins counting from the top 1. .

13+15+...117 and 1□ have been removed.

Therefore, the distance between the remaining accommodation pins is 2X. Therefore, the remaining storage pins can store 100 sheets per pin, which is double the normal number.

In the state shown in Fig. 3 in which the storage pins of the sorter are removed every other pin, 100 sheets of paper can be stored per pin, so when copying 10 copies of the 60 sheets of original described earlier, Able to perform work.

In this way, when copying multiple pages of originals, etc.
It can be made into an easy-to-use sorter.

In this embodiment, the housing pins 11 to 1□. are both trunnion 2. ~2□. Since it is removable from the holder, it is only necessary to remove any accommodating pin depending on the number of originals and the number of copies. For example, by leaving a housing pin at every second pin and removing the other housing pins, it is possible to
It is also possible to accommodate 0x3 to 150 sheets of paper.

In this embodiment, all receiving pins 1, ~120 are trunnions 21~2°. However, among the 20 pins, the odd numbered accommodation pin Ill 1 counting from the top
3.15. ..., 117 and 18. Only one of the receiving pins may be configured to be detachable from the trunnion, and the remaining accommodation pins may be configured to be non-removable.

In the above explanation, we have focused on a movable pin type sorter, but in the case of a fixed pin type sorter in which the paper ejection position changes like an elevator, it is also possible to make the storage pins removable. This allows the capacity per pin to be increased. .

<Effects of the Invention> Since the present invention is configured as described above, it is possible to provide a sorter with good workability in which the number of accommodated pins can be changed according to the content of the work.

Further, by removing the storage pins, the number of sheets stored per remaining storage pin can be increased, so it is possible to improve the efficiency of sorting the sheets on which images have been formed.
