DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing a schematic configuration of a copying apparatus according to the present invention, FIG. 2 is a perspective view showing a schematic configuration of an optical system in FIG. 1, FIG. 3 is a control block diagram of the present invention, and FIG. 4 is a control block diagram of the present invention. It is a flowchart.

First, the configuration of a copying apparatus according to the present invention will be explained with reference to FIGS. 1 to 3. An optical system 2 is disposed at the upper part of the copying apparatus main body 1 . This optical system 2 is
It has a copy lamp 3 made of a halogen lamp or the like, a plurality of mirrors 4 to 7, and a zoom lens 8.

The copy lamp 3 and the mirror 4 are attached to a first mirror base 10 as shown in FIG. 3, and the mirrors 5 and 6 are attached to a second mirror base integrally connected to the first mirror base 10. It is attached to 11. The first and second mirror bases 10 and 11 are supported by a pair of guide bars 12 and 13 so as to be able to reciprocate in the A and reverse A directions.

Lateral protrusion 1 of first mirror base 10
A wire 14 is connected to Oa, and this wire 14 is wound around pulleys 15 and 16. The pulley 16 is driven by a motor 18 via a wire 17.
The first and second mirror bases 10 and 11 are configured to move in the direction A or in the reverse A direction via the wire 14 as the mirror 6 rotates.

Home positions of the first and second mirror bases 10 and 11, that is, the first and second mirror bases 1
A home position sensor 20 is arranged at the end of movement in the reverse A direction of 0 and 11, and this home position sensor 2
0 detects the downwardly bent portion 10b provided on the protruding portion 10a of the first mirror base 10.
It is designed to detect that the mirror bases 10 and 11 are located at the home position.

A photoreceptor 21 is rotatably supported below the optical system 2. Around the photoreceptor 21, as is well known, there are a charger 22, a developing section 23, a transfer device 24, and a static eliminator 2.
5th grade is placed. When copying, the first and second mirror bases 10 and 11 are moved to A with the surface of the photoreceptor 21 being charged to a predetermined potential by the charger 22.
A document (not shown) that is moved in the direction and covered by the document cover 26 is placed on the first and second mirror bases 10 and 11.
As the mirror moves, the copy lamp 3 on the first mirror base 10 sequentially irradiates the light from the tip. Then, the photoreceptor 21 is exposed to the reflected light from the original via the optical system 2, thereby forming an electrostatic latent image on the photoreceptor 21.

When an electrostatic latent image is formed on the photoreceptor 21,
Subsequently, this electrostatic latent image is developed with toner supplied from the developing section 23 to form a toner image. Thereafter, paper (not shown) is sent from the paper feed unit 30, which includes a plurality of paper cassettes, etc., to the registration rollers 31, and after being temporarily stopped by the registration rollers 31 as necessary, the paper is delivered at a predetermined timing. It is supplied to the photoreceptor 21. Then, the toner image is transferred onto the supplied paper by the transfer device 24. Thereafter, the paper is peeled off from the photoreceptor 21 and transported by a transport device 32 to a fixing section 33, where the toner image is fixed onto the paper.

When the fixed paper is one-sided copying and does not require stapling, it passes through conveyance paths 41 and 42 of a finisher 40 connected to the side of the main body 1 and is delivered to a paper output tray 3.
It is discharged at 4. The finisher 40 is provided with one stapler 47 and one paper discharge tray 34.

On the other hand, in the case of composite copying or double-sided copying,
The paper sent out from the fixing unit 33 is conveyed through the paper conveyance path 35, and is stored as is in the intermediate tray 36 for composite copying, and after being reversed by the paper reversing unit 37 for double-sided copying. It is accommodated in the intermediate tray 36.

When a predetermined number of sheets of paper are stored in the intermediate tray 36, the paper feeding roller 38 moves the sheets to the intermediate tray 36.
The uppermost sheets of paper are sequentially conveyed to the photoreceptor 21 again for composite copying or double-sided copying, and when stapling processing is not required, they are sequentially discharged to the paper discharge tray 34 of the finisher 40.

When stapling processing is required, the fixing section 3
The sheets conveyed from No. 3 to the finisher 40 pass through conveyance paths 43 and 44 and are sequentially stored in a stapling tray 45. Since the staple processing tray 45 is inclined in the advancing direction, the leading ends of the stored sheets are aligned by the stopper 46. When a predetermined number of sheets are stored, the stapler 47 staples the sheet stack, and a solenoid 46 (not shown) causes the stopper 46 to
will be opened. Therefore, the stapled paper is conveyed through the conveyance path 42 and discharged onto the discharge tray 34.

The structure of the CFF will now be explained with reference to FIG. A CF mounting table 28 for placing a CF original is provided on the side of the original table on the top surface of the main body 1 or on the left side of the main body, and a CF ejection tray 48 is provided on the right side of the main body 1 for ejecting the copied CF original. is provided.

Further, a sprocket 29a and a motor 29b for driving the sprocket 29a are provided near the document table of the main body 1. CF is the above sprocket 29
A is rotated and transported from the CF mounting table 28 between the document cover 26 and the document table, and after copying is completed, C
It is discharged onto the F discharge tray 48.

The operation of the copying apparatus is controlled by a master C shown in FIG. 3 which also functions as a copy lamp lighting control device.
PU101 and a slave CPU that controls the optical system 2, etc.
102.

The master CPU 101 operates the operation panel 105 according to a program stored in the ROM 103 in advance.
The slave CP receives signals from the keys and sensors above.
A signal that instructs U102 to start moving the first and second mirror bases 10 and 11 in the A direction, and a signal that returns the first and second mirror bases 10 and 11 that have finished moving in the A direction to their home positions, etc. It is designed to transmit.

The master CPU 101 also controls the supply and stop of voltage supply to the copy lamp 3 via the copy lamp lighting circuit 106, and also adjusts the effective voltage level applied to the copy lamp 3.

On the other hand, the slave CPU 102 uses the ROM 10
Motor 1 according to the program stored in advance in 4.
The motor 18 receives a signal from a rotary encoder 53 that detects the rotational speed of the motor 8 and a signal from a home position sensor, and controls the rotational speed of the motor 18 via a driver 107 .

[0027] Furthermore, the slave CPU 102 has a CF
Controls the rotation of the motor 29b for operating the sprocket 29a of F27.

The slave CPU 102 also controls the switching of the switching gate 49 to determine whether the paper that has passed through the fixing section 33 is transported toward the finisher 40 or toward the intermediate tray 36, and further controls the switching of the switching gate 49 to determine whether the paper that has passed through the fixing section 33 is transported toward the finisher 40 or toward the intermediate tray 36. It controls the paper feed roller 38 that sequentially feeds the stored paper sheets starting from the top one.

In the copying apparatus configured as above, C
The operation for copying two copies of F original and stapling them will be described with reference to the control flowchart in FIG. 4(a). Set 2 copies in CFF mode and copy the CF original to CF
The paper is placed on the mounting table 28 and set so as to be transportable, and a print switch (not shown) is pressed to start copying (step n1).

First, the first copy of the first CF original is copied (step n2), and the copied paper is transferred to the finisher 4.
0, passes through the transport paths 43 and 44, and is stored on the stapling tray 45 (step n3).

Next, the second copy of the first CF original is copied (step n4), but since this is the second copy, the gate 49 for switching the conveyance path is activated so that the paper is not conveyed toward the intermediate tray 36. Therefore, the second set of sheets does not go toward the finisher 40, but is transported along the transport path 35 and stored in the intermediate tray 36 (step n5).
.

[0032] When the first copy of the CF original is completed, the number of punched holes specified in advance according to the CF paper size is
Feed the F original (step n6). And C.F.
The presence or absence of an original is detected (step n7), and if a CF original is present, the process returns to step n2 and the first copy of the second CF original is copied. Thereafter, the operations from step n2 to step n7 are repeated until there are no more CF documents left.

If it is determined in step n7 that there is no CF original, the first set of sheets is stapled by the stapler 47 (step n8), and the stapled sheet is discharged to the paper output tray 34 through the conveyance path 42. (Step n9).

When it is detected that the first set of sheets has been ejected, the second set of sheets stored in the intermediate tray is sequentially conveyed to the stapling tray 45 of the finisher 40 through the same path as during copying. It is accommodated (step n10). When all the sheets of the second set are stored in the staple processing tray 45, the second set of sheets is stapled by the stapler 47 (step n11), and is discharged to the paper output tray 34 through the conveyance path 42, and the operation completes one cycle. ends. If two or more copies are to be made, for example if ten copies are required, the above series of operations may be repeated five times.

Furthermore, if stapling processing is not required, the operation may be controlled according to the flow shown in FIG. 4(b). Since the flow up to step n7 is almost the same as the flow in (a), only the differences will be explained. In the flow of (a), the first set of paper is placed on the stapling tray 45 in step n3.
However, in the case of (b), stapling processing is not required and the sheets are directly discharged to the paper discharge tray 34.

When the copying of the CF original is completed, the second copy of paper stored in the intermediate tray 36 is sequentially discharged to the paper discharge tray 34 of the finisher 40 through the same path as during copying. At this time, if the paper ejection tray 34 is made slidable in the front-rear direction of the copying machine, the first copy of paper and the second copy of paper can be reliably sorted.

[0037]

According to the copying apparatus of the present invention, two sets of sheets can be reliably sorted without adding a paper ejection tray.

Furthermore, since the first set of sheets and the second set of sheets can be taken out from the same location, the taking out operation can be carried out smoothly.

Furthermore, according to claim 2 of the present invention, after detecting that the first set of sheets has been stapled and has been discharged to the paper output tray, the second set of sheets is conveyed to the stapling processing tray. Since the first and second copies are stapled together, the first and second copies are accurately stapled.
