Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention can be connected to the next stage, and the received sheet can be transferred between its own storage section and the next stage provided at the connection section with the next stage. This relates to a sheet storage device with a sheet feeding means that selectively transports sheets to a sheet feeding port and a sheet feeding port. It is used to sort and store parts one by one in separate storage sections, or to store one or more copies in a non-sort storage section without sorting.

(Prior Art) In a processing device, especially a copying machine, that feeds sheets into this type of sheet storage device, when a series of many originals are being copied, a small number of originals such as one or several sheets, Copying may be required for urgent manuscripts. In this case, if the sheet storage device handles the copies made up to that point and the copies made later in the same manner, they will be mixed up.

A sheet storage device designed to prevent such problems is known from Japanese Utility Model Application Publication No. 59-64848. In this system, a non-sort storage bin and a large number of sorted storage bins are set up, and when there is an interruption copy during non-sort storage mode, the interrupted copy is stored in any bin other than the non-sort storage bin, that is, in any sorted storage bin. I try to do that.

(Problems to be Solved by the Invention) However, in the conventional case, sheets that have been interruptedly copied can only be stored in the section in the non-sort storage mode. In addition, sheets that have been copied are carried out immediately after copying, but they are difficult to take out because they are stored in narrow, multi-layered sort storage bins for sort storage.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention is capable of connecting to the next stage, and connects received sheets to its own seat storage section and the next stage. In a sheet storage device having a sheet conveying means for selectively conveying sheets to a sheet discharging port for the next stage provided in a section, a sheet receiving device that is attached to and detached from the sheet discharging port when the sheet is not connected to the next stage. a tray; a means for detecting whether or not the sheet receiving tray is attached to a sheet delivery port; The apparatus is characterized by comprising a control means for controlling the sheet conveying means so as to send the sheet to the sheet receiving tray.

(Function) A sheet storage device that can be connected to the next stage, and selectively conveys received sheets to its own sheet storage section and a sheet delivery port for the next stage connected to it by a sheet conveying means. The sheets can be stored in the own sheet storage section in a sorted or non-sorted state, or can be sent out to the sheet delivery port.

When there is no connection with the next stage, a sheet receiving tray can be removably attached to the sheet delivery port, and the receiving sheet can be sent out by the sheet conveying means, thereby eliminating the need to improve or install a new sheet conveying means. It can now be used as a single storage unit.

When the sheet receiving tray is used as a sheet storage section and the sheet receiving tray is attached by controlling the sheet conveying means by the control means, and when an interrupt process is performed in a processing device such as a copying machine, Since the interrupted sheet is discharged to the sheet receiving tray, it is possible to prevent it from being mixed with sheets that have already been stored according to the setting mode and will be stored according to the setting mode from now on.

Further, the sheet receiving tray can be of an open type to the outside so that stored sheets can be easily taken out.

(Example) An example of the present invention shown in FIGS. 1 to 6 will be described. This embodiment shows the case of a sheet storage device B which is connected to a copying machine A in FIG. 1, and a sheet storage device C or the like can be connected to the next stage.

The sheet discharge port 10 is formed between movable rollers 19 and 20 on which conveyor belts 13 and 14 are stretched, which are provided on a slider 18 that slides up and down on the back of the machine. As a result, when the slider 18 is moved up and down, the sheet discharge port 10 is moved up and down, and by controlling the movement position, the sheet discharge port 10 is moved up and down to each sheet storage bin 2. The conveyor sheet can be sent out selectively facing any of - and -.

A switching pawl 21 for switching the direction of sheet travel is provided at the branching point between the first conveyance path 7 and the second conveyance path 8, and a solenoid (FIG. 6) 47 directs the sheet to the second conveyance path 8. When the sheet is switched between the orientation of directing the paper and the orientation of moving straight along the first conveyance path 7, and the sheet is directed toward the second conveyance path 8, it is discharged through the second conveyance path 8 to the sheet storage tray 1 for non-sorting.

A switching pawl 22 for switching the sheet traveling direction is also provided at the branching point between the first conveying path 7 and the third conveying path 9. 3, the posture is switched to the position facing the conveyance path 9,
When the sheet advances straight, it is sent out from the sheet delivery port 4, and when the sheet is directed to the third conveyance path 9, it is sent through the 31st conveyance path 9 to each sheet storage bin 2. The sheets can be sorted and stored in -.

The copying machine A is provided with a fixing device 31 for connection with the sheet storage device B, and a sheet conveyance path 33 that feeds the ejected sheet after passing through a pair of ejection rollers 32 to the sheet receiving port 3 of the sheet storage device B. . This sheet conveyance path 33 also has a sheet guide 4.
5 and a guide roller 46.

The next stage sheet storage device C is the same as the sheet storage device B except that it does not have a non-sorting sheet storage tray and a sheet delivery port to the next stage.

The sheet storage device B is equipped with a sheet receiving tray 41 for non-sorting as shown in FIG. 3, which can be attached to and removed from the sheet delivery port 4 when it is not connected to another sheet storage device C. The sheet receiving tray 41 has mounting projections 42 on the left and right sides of its base end, and the projections 42 are inserted into mounting holes 43 formed slightly below the sheet delivery port 4 as shown in FIG. 3, as shown in FIG. It can be attached and detached by inserting it as shown. Inside the mounting hole 43 is a protrusion 42 when the sheet receiving tray 41 is installed.
A detection switch 44 that is pushed by the user is provided to detect whether the sheet receiving tray 41 is attached or detached. The entire sheet storage device B with the sheet receiving tray 41 attached thereto is as shown in FIG.

A detection switch 61 for detecting the presence or absence of the connection is also provided at a connection portion of the sheet storage device B with another sheet storage device C. Further, a photosensor 62 for detecting a discharged sheet is provided immediately after the pair of paper discharge rollers 32 of the copying machine A.

Sheet storage device B, together with other sheet storage devices C, etc., has a CPU+ (control means) for operation control.
Serial data communication is performed with the CPU0 on the side, and related control is performed with the copying machine A (FIG. 6). For this purpose, a photo sensor 62 and an interrupt key 63 for interrupt copying operation on the copying machine A side are connected to the CPU, and the driver circuits 51 and 52 of the solenoids 47 and 48 are connected to the CPIJ I of the sheet storage device B. , drive motor 4 of sheet conveying means 6
9 driver circuit 53, and detection switch 44.6
1 is connected.

The operation control mainly when the interrupt key 63 is pressed will be explained below based on the flowchart shown in FIG.

First, in step #1 of FIG. 7, normal copying processing according to the setting mode is started, and during this operation, in step #2, it is determined whether or not the interrupt key 63 is turned on in the copying machine A.
If it is not turned on, the process directly proceeds to step #7, performs other processing, and returns to step #2.

If the interrupt key 63 is turned on in step #2, the process moves to step #3, where it is determined whether the detection switch 44 is turned on, that is, whether the sheet receiving tray 41 is attached to the sheet storage device B. If it is installed, the solenoid 47 is turned off and the solenoid 48 is turned on in step #4, and the sheet received in the first conveyance path 7 is transferred to the second conveyance path 7.
Step #5
Then, interrupt copying operation is performed.

If the sheet receiving tray 41 is not installed in step #3, sheets cannot be ejected using it, so step #4 is skipped and the process moves to step #5 to perform an interrupt copying operation.

As a result, when the sheet receiving tray 41 is attached, the sheet that has been copied is stored therein. If the sheet receiving tray 41 is not installed, it is stored according to the setting mode. However, in this case, it can also be stored in any storage section.

After the interrupt copying operation in step #5, in step #6, it is determined whether the interrupt copying has ended based on the presence or absence of a normal copying operation start operation signal, etc., and if it has not ended, return to step #5 and repeat the interrupting copying operation. , and step #
7, other processing is performed, and the process returns to step #1.

(Effects of the Invention) Since the present invention has the above-described structure and operation, by mounting the sheet receiving tray in a state where it is not connected to the next stage, sheets that have been subjected to processing such as copying in an interrupt can be retrieved. It is possible to distinguish the sheet from non-scratched sheets that have been ejected to the sheet receiving tray, have already been stored according to the setting mode, and will be stored later according to the setting mode, and the trouble of having to separate them manually can be saved. Further, since the sheet receiving tray can be kept open to the outside, it is convenient to take out stored sheets that have been processed for erroneous settings.
