Next, the operation of the above device will be explained as follows.

The size of the long recording sheet 1 wound into a roll is set, for example, by turning on an operation button (not shown) on the operation section (see FIG. 7, 23).

If a large size larger than the so-called Al size is selected here, the plunger 18 moves ONL, the swing guide 16 moves in the direction B around the swing shaft 17, and its horizontal tip touches the surface of the paper ejection tray guide 15. be in contact with and paper ejection roller 1
Preparations for introducing the large-sized recording sheet la sent from 1 into the take-up box 13 are completed. On the other hand, a long recording sheet pulled out from roll lb! Alternatively, large-sized recording sheets supplied from the storage section W) 1a are both conveyor rollers 5.
．． 6, the image is sent to the image forming section 7. After an image is formed in the image forming section 7, the sheet is sent out by a sheet discharge roller 11. Then, the paper ejection guide 14, l movement guide 16
It passes through the long guide 20, is introduced into the winding box 13, and is automatically wound up within the winding box 13 while being guided in contact with the guide ribs 13b. Large-sized recording sheets 1a are introduced one after another into this winding box 13.
are wound up concentrically as illustrated in FIG. 3 by the conveying force of the paper ejection roller 11 and the like. Note that the long recording sheet la is cut by the cutter 4 after an image is recorded in the image forming section 7. On the other hand, the movement of the recording sheet la stops when the rear end of the recording sheet 1a comes off the paper ejection roller 11, but the sensor 21 remains ON while detecting the rear end of the recording sheet 1a. Do not perform the following actions.

Then, when the user takes out the recording sheet la from the take-up box 13 in the D direction (Fig. 3), the sensor 21 is turned off for the first time.
It is configured so that it can be set to F and perform the following operations.

Furthermore, if the size of the recording sheet la is smaller than the AI size, the plunger 18
remains OFF, and the swing guide 16 is held at its normal position by the return spring 19 with its horizontal tip separated from the surface of the paper discharge tray guide 15. Therefore, a recording sheet (not more than AI size) 1a obtained by cutting a long recording sheet (1) discharged by the paper discharge roller 11, or a recording sheet (not more than AI size) which is stored in advance as a sheet in the storage section W and supplied from the storage section W. Both of the recording sheets 1a pass through the paper discharge guide 14 and the paper discharge tray guide 15, fall into the paper discharge tray 12, and are stored therein.

Next, in the above configuration, using FIGS. 7 and 8, plunger 18 in long recording using a large size recording sheet and small size recording using a small size recording sheet.
A method of controlling ON and OFF will be explained.

The block diagram of the control of the image recording device (printer) C is shown in the seventh
It looks like the picture. The operation unit 23 is a means for inputting the document size, magnification, number of recording sheets, etc. CPU24
determines the optimum sheet size based on the information input from the operation unit 23 and sends the information to the printer control unit 25. The printer control unit 25 uses a plunger 18, a paper feed motor 22a, a paper discharge motor 22b, and a sensor 21. Plunger 8, which controls various parts such as clutches installed on rollers 3, 5, 6゜8.9.10
is turned ON by a signal from the printer control unit 25 when the optimum sheet size of the recording sheet is large (for example, Al size or larger in this embodiment). Further, if the optimum sheet size is a small size (for example, less than AI size), the ON signal is not generated and remains OFF.

The flow of the control method will be explained using the flowcharts shown in FIGS. 8 and 9 and FIGS. 1 and 2.

In step Sl, the user inputs the document size from the operation section 23. Furthermore, in step S2, input the same magnification, enlargement, or reduction magnification from the operation unit 23, and then proceed to step S2.
Proceed to 3.

In step S3, the CPU 24 determines the optimum sheet size based on the information, and if the optimum sheet size is a large-sized long record, the process proceeds to step S4, and if it is a small size, the process proceeds to step S10. proceed.

In step S4, the plunger 18 is turned on, the swing guide 16 moves in the direction B about the swing shaft 17, and the process proceeds to step S5.

In step S5, the paper feed motor 22& begins to rotate, transmitting power through a chain (not shown), and in step S6, the clutches provided to the roller groups 3, 5.6 are turned on, respectively, thereby moving the rollers 3, 5.6, respectively. The recording sheet l is rotated and sent to the image forming section 7.

In step S7, an image is recorded on the recording sheet 1 in the image forming section 7, and at the same time, the recording sheet 1 after the image formation is sent out by the paper ejection roller 11. The image forming unit 7 records an image signal corresponding to an image read by a document image reading device (not shown) attached to the image recording device C, or an image corresponding to an image signal sent from another device. Next, in step S8, when the recording sheet 1 has been fed to a predetermined length, the clutch built into the cutter 4 is turned on to operate the cutter, and the recording sheet 1 is moved to the trailing edge of the recorded image. The sheet is cut into a long sheet-fed recording sheet la, which is ejected by the ejection motor 22b in step S9.

Thereafter, the sheet-fed recording sheet) 1a is moved to the paper ejection guide 14, the swinging guide 16, and so on. The sheet passes through the long guide 20 and is introduced into the winding box 13, comes into contact with the guide ribs 13b inside the winding box 13, and is naturally wound up by the conveying force of the rollers 11 and the like.

Next, when the optimum size of the recording sheet la is small, the plunger 18 remains OFF and the swing guide 16 is held at the normal position by the return spring 19 in step SIO.

In step Sll, the paper feed motor 22a is turned on to feed a small size sheet, and the process proceeds to step S12.

In step S12, the rollers 8, 9, 10, and 5°6 are moved to the ONL and the small size recording sheets supplied from the storage section W, respectively.
a is sent to the image forming section 7, where an image is formed, and the process proceeds to step S13.

In step S13, the paper discharge motor 22b is turned on, the paper is discharged by the paper discharge roller 11, and the paper discharge guide 14. The paper is stored in the tray 12 via the paper discharge tray guide 15.

Note that in the above explanation, the small-sized recording sheet la was fed from the storage section W, but the small-sized recording sheet 1a formed by cutting the roll-shaped recording sheet 1 into small sizes with the cutter 4 is Even if the plunger is used, the movement of the plunger 18° is the same.

In the flowchart shown in FIG. 8 above, the CPU determines the size of the recording sheet by inputting the original size and magnification on the operation unit 23 by the user, but conversely, the CPU determines the size of the recording sheet. Enter whether to use a leaf sheet or a long sheet wound into a roll, and if it is a sheet, it will be ejected to the paper output tray 12, and if it is a large size recording made of a long sheet, it will be cut. rear seat 1a
It is also possible to control the pusher 18 so as to discharge the paper to the take-up box 13.

This case will be explained using the flowchart shown in FIG. First, in step S1, when the user inputs the size of the recording sheet that he or she wants to use on the operation section 23, step S1
In step 2, the CPU 24 determines whether the input size is such that a long recording sheet should be fed or a cut sheet in a cassette should be fed.

If the determined result is that a long sheet is to be fed, the process proceeds to step S3, and if the determined result is that a cut sheet is to be fed, the process proceeds to step S9.

In step S3, the plunger 18 is moved ONL, and then, as explained in the flowchart of FIG. As it moves, its horizontal tip comes into contact with the surface of the paper discharge tray guide 15.

When feeding a cut recording sheet, the plunger 18 remains OFF and the swing guide 16 is held at its normal position by the return spring 19 in step S9. Thereafter, in steps 310 to S12, the large-sized recording sheet (1a) is introduced into the winding box 13 and wound up, through the same process as when the user inputs the document size and magnification. In the case of recording sheets, the paper ejection guide 14
The paper passes through the paper discharge tray guide 15 and falls and is stored in the paper discharge tray 12.

According to the above embodiment, by winding and receiving a long sheet in the take-up box 13, which is a storage body, and storing small-sized recording sheets in the tray 12, a space for storing the long recording sheets is created. The long recording sheet can be prevented from being damaged or folded by being received in the take-up box 13 while being rolled. Further, by storing small-sized recording sheets in a separate tray 12, it is not difficult to take out both recording sheets.

(Other Examples) In the above embodiment, a large size recording sheet (1a) obtained by cutting a long recording sheet 1 is stored while being rolled up in the winding box 13, and a small size recording sheet (1a) is a separately provided small size recording sheet (1a). Although the recording sheet 1a of different sizes is configured to be stored in the tray 12 according to the size, it is also possible to store the recording sheets 1a of different sizes in a common storage tray as shown in the following example.

That is, in FIGS. 4 and 5 (A) to (E).

Reference numeral 26 denotes an apparatus common tray, which is configured to be able to accommodate both large-sized recording sheets la larger than Al size and small-sized recording sheets la smaller than Al size. The inner bottom portion 26a of the common tray 26 is curved in an arc shape, and is configured so that the large-sized recording sheet la can be automatically curled and rolled up at this portion. Also, the entrance portion 26c of the upper part 26b of this common tray 26 is connected to the paper discharge tray guide 1.
It has a nip 26d sufficient for the tip of the recording sheet 1a sent along the curved line 5 to fall into the curved inner bottom 26a, and the recording sheet introduced into the inner bottom 26a from this nip 26d 1a can be automatically bent.

Therefore, in this embodiment, the recording sheet 1 before being cut
When is selected, as shown in FIG. 5(C), the recording sheet 1 ejected by the paper ejection roller 11 is guided from the nip 26d of the entrance 26c of the common tray 26 to the inner bottom 26a, and then the paper ejection roller 11 ejects the recording sheet 1. 11, the recording sheet 1 is gradually wound up in the direction of arrow A', and then cut, and the rear part of the recording sheet 1 is placed on a tray 26 as shown in FIG. 5(D).
is supported by the terrace portion 26e of the entrance portion 26c.

Next, we will explain the recording sheets 1a that have been cut into sheets.Among the recording sheets 1a, the large-sized recording sheet 1a, which is larger than the AI size, has its leading edge inside, as shown in FIG. 5(D). Paper ejection is completed in a state where the bottom portion 26a is slightly curved and the vicinity of the rear end is supported by the input rotary portion 26e of the common tray 26.

The smaller size recording sheet) 1a is as shown in Figure 5(D),
Paper ejection is completed with almost the entire recording sheet 1a stored in the tray 26.

Next, when taking out the recording sheets stored in the tray 26, since the rear ends of the long recording sheet 1 and the large size recording sheet la are exposed from the tray 26, the 51st N(0) or D
It is also possible to take it out while rolling it in the direction. In addition, in the case of a small size recording sheet 1-1a, if the machine has a two-sided standard as shown in FIG. 5(A), by shortening the tray 26 by a certain amount on the standard side, It is possible to pull out the recording sheet la. In addition, if the machine is based on the center, by using a tray 26 with a small horizontal width, the recording sheet la will be exposed on both sides of the tray 26, so that it can be pulled out to either side. Or, as shown in FIG. 5(E), the terrace portion 26e of the tray 26
By pulling FjiB 28c of the tray 26 wider, the rear end of the recording sheet can be pulled in the direction of arrow E and easily taken out.

According to the above embodiment, recording paper of various sizes can be shared by one
Since the recording sheets can be stored in one storage tray 26, the space for storing the recording sheets can be further reduced. Further, since a large-sized recording sheet, that is, a long recording sheet can be stored in the tray 26 while being rolled up, damage or bending can be prevented.

Subsequently, the embodiments shown in Nos. 6rA(A) to (E) are further improvements of the embodiment shown in FIG. 5 described above. still,
The perspective view of FIG. 4 is also common to this improved embodiment.

In this embodiment, a partition plate 27 is attached to the sandwiching portion 26d of the entrance portion 26c of the common tray 26.

The partition plate 27 is made rotatable by a solenoid 29 about a fulcrum 28, and the tip of the partition plate 27 is urged against the narrow face 26f of the tray 26 by the tensile force of the spring 3o. The entrance to the inner bottom 26a is closed.

Therefore, by turning on the solenoid 29, the partition plate 27 is rotated in the direction of arrow F in FIG. 6(A) against the tensile force of the spring 30 (FIG. 6(D)), opening the entrance of the inner court 26a. The opening is configured to allow the recording sheet to pass through this entrance.

In this embodiment, when a small-sized recording sheet 1& made of cut sheets is selected, the solenoid 29 is turned off and the partition plate 27 closes the entrance of the inner bottom 28a of the tray 26. It's closed. Therefore, as shown in FIGS. 6(B) and 6(C), the ejected small-sized recording sheet la is not inserted into the inner bottom portion 26a but is supported by its entrance portion 26c or terrace portion 26e. Paper ejection is completed in this state.

If large size recording sheet la is selected, the sixth
As shown in Figure CD), the solenoid 29 is turned on to release the partition plate 27 from closing the inlet of the inner bottom 26a.

Then, the leading end of the recording sheet 1a is inserted into the inner bottom portion 28a and wound up while being curved, so that the recording sheet 1 can be discharged.

Further, as shown in FIGS. 6(E) and 6(F), a cam 31 is used in place of the solenoid 29, and by rotating this cam 31 by 180 degrees by a drive source (not shown), the partition plate 27 can be moved in the same manner as the solenoid 29. It is also possible to operate it. Note that the solenoid 29 is controlled by the printer control section 25 described above.

In the above embodiment, for convenience, the AI size was divided into large size recording sheet (1a) and small size recording sheet (1a), but it is of course possible to change the standard size as necessary. .

Also, inside the large size recording sheet 1a, the leading end of the long recording sheet 1 begins to be wound up in the winding box 13 or the common tray 26, and is then cut into a predetermined length by the cutter 4. An extremely long large size recording sheet 1a, and a large size recording sheet l whose rear end is cut by a cutter 4 before the leading end reaches the take-up box 13 or the common tray 26.
It should be noted that this includes 1a, or a general large-sized recording sheet 1a, which is supplied in advance as a sheet.

As described above, the apparatus according to this embodiment has a tray 26 which is a storage body that can store large-sized recording sheets while winding them up.

Therefore, in the case of this storage device 100, when a large size recording sheet 102, for example, Al size or larger, is selected by the operation unit 23, the plunger 116 is actuated against the swinging spring 114 to fix the swinging plate 113 and this sheet. The lower portions of the moving guides 1lla are moved to the left, respectively, to open the bottom of the upper storage portion 110a and form a gap through which the recording sheet 102 passes. Therefore, the recording sheet 102 discharged from the paper discharge roller 104 is guided by the paper discharge tray guide 103 or the lifting prevention guide 122, and is introduced into the upper storage section 100a, and passes through the gap at the bottom thereof under its own weight. And as mentioned above, the motor 11
It is wound up while being curved in the direction of the arrow in sequence by a large number of bells (117) driven by (8). The recording sheet 102 wound up in this manner can be taken out in the F direction.

Next, a small recording sheet (less than AI) 102 is the operation section 2.
3, the swing plate 113 and the lower part of the moving guide 1lla are moved to the right by the action of the swing spring 114. Then, the lower part of the moving guide 1lla comes into close contact with the guide stopper 111b, and the upper storage part 10
Small size recording sheet 1 to close the gap at the bottom of 0a
02 is stored in the upper storage section 100a. Further, this recording sheet 102 can be easily taken out as it is in the direction of arrow G.

As described above, the apparatus according to the present embodiment has a winding storage section in which large-sized recording sheets can be stored while being rolled up, and small-sized recording sheets can be stored as they are. Therefore, there is no need for a large tray like in the past, and the recording sheets ejected from the paper ejecting unit can be processed in a small storage space.
Moreover, recording sheets of large and small sizes can be smoothly stored in a single storage device that serves both purposes. Therefore, it is possible to prevent the occurrence of damage or bending of recording sheets that protrude from the tray as in the past, and furthermore, the stored sheets can be taken out smoothly, and even if the user is not attached to the device, it can be automatically removed. It has characteristics such as being able to be processed.

Still another embodiment will be described with reference to FIGS. 13(A) and 13(B).

The sheet processing apparatus 130 of the present embodiment has a substantially rJ shape having a vertical portion 130a and an arcuate portion 130b connected thereto. A plurality of rows of ribs 135 are provided on the vertical portion 130& and the arcuate portion 130b over the entire width thereof along the sheet conveyance path. and arc portion 130
A roller 131 is provided between each rib 135 located at b.

133 are arranged alternately with respect to the conveying direction of the recording sheet (direction A in the figure). Furthermore, this Koro 131,
133 is a shaft 132 and 134 provided between each rib 135
It is rotatably attached between each rib 135 by. Here, the rollers 131 and 133 are disposed in a direction perpendicular to the recording sheet conveyance direction over a range slightly wider than the sheet width.

Therefore, the leading edge of the recording sheet 136 discharged from the recording device C by the discharge roller 124 first reaches the rib 135.
The roller 131 is guided by the circular arc portion 130b. Here, since the rollers 131 are rotatable, the leading edge of the recording sheet 136 moves smoothly and hits the next roller 133. This roller 133 also rotates in the same way as the roller 131, and smoothly transfers the recording sheet 133.
proceed. In this way, the long recording sheet 136
The recording sheet smoothly passes through the arcuate portion 130b in the storage device 130 and is then wound up while being curved in the direction of arrow B. Also in this embodiment, it is possible to smoothly store a long recording sheet while winding it up. Can be done.

(Effects of the Invention) As explained above, according to the sheet processing apparatus of the present invention,
By being equipped with a storage body that can hold the sheet while rolling it,
Even a sheet processing device that stores long sheets can be installed in a small space. Also, by receiving the sheet while rolling it, it is possible to prevent the sheet from being damaged or folded.
