Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a copying machine in which a post-processing device such as a sorter, a stunner, a slitter, etc. is connected to a copying machine.

[Prior art]

Copying machines often include a sorter for sorting and collating the copies, a Stanno-1 machine for stamping various stamps on the copies, or a machine for shearing the copies into predetermined sizes. A post-processing device such as a stacker is often connected. In this case, it is necessary to transmit corresponding control signals from the copying machine to the post-processing device. Therefore, conventionally, each time the type of post-processing device to be connected is changed, the configuration of the copying machine side control device and the configuration of the connecting portion between the copying machine side and the post-processing device side are changed each time. However, for this reason, there are problems in that the productivity of this type of copying apparatus decreases and the cost increases.

〔the purpose〕

SUMMARY OF THE INVENTION An object of the present invention is to provide an economical copying apparatus by minimizing changes to the copying machine when connecting it to a post-processing device.

〔composition〕

FIG. 1 shows a configuration diagram of a copying apparatus according to an embodiment of the present invention when a sorter is used as a post-processing device.
1 is a copying machine, and 2 is a sorter.

On the copying machine 1 side, the surface of the photosensitive drum 3 rotating in the direction of the arrow is cleaned by a cleaning device 4, neutralized by a neutralizing charger 5, and then uniformly charged by a charging charger 6. On the other hand, the original placed on the contact glass 7 is exposed and scanned by an optical system consisting of an exposure run 8, a mirror 9, and a lens system 10. This exposure scanning light forms an electrostatic latent image corresponding to the original on the uniformly charged photosensitive drum 3. This electrostatic latent image is developed into a toner image by a developing device 11 and then brought to a transfer position. On the other hand, the transfer paper 13 stored in the cassette 12 is transferred to the paper feed roller 14 by the registration roller 1.

This transfer paper 13 is guided by a deflection claw 33 that is deflected by turning on a solenoid (not shown) and is discharged into a predetermined bin 34. In addition, 35 is a turn guide, and 36 is a light emitting element 36.
Entry sensor consisting of A1 light-receiving element 36B, 37 is a jam sensor.Although the above is just a very general configuration of the sorter 2, in the case of this embodiment, in addition to this configuration, There is an optical mark reading device at the entrance of sorter 2, that is, on the upstream side! (
It is characterized by the arrangement of an OMR (hereinafter abbreviated as OMR) 38 and an entrance switching guide plate 39.

The inlet switching guide plate 39 is normally held at the solid line position shown in the figure by the force of the spring 40, and when the solenoid 41 is turned on, it is rotated in the direction of the arrow and switched to the one-dot chain line position. Therefore, the transfer paper 13 discharged from the copying machine 1 is normally transferred to the bin 3 according to the solid line position of the entrance switching guide plate 39.
However, when the entrance switching guide plate 39 is switched to the position indicated by the dotted line in the figure, it is discharged onto the brew tray 42.

Figure 2 shows the operation and
A block diagram of the main channel 50 is shown, in which 51 is a star, 152 is a sort key, 53 is an interrupt key, 54 is a numeric key, 55 is a clear key, and 56 is a print key.

With the above configuration, after pressing the mode selection key on the operation/gunnel 50 and setting the number of sheets or copies using the number key 54, when the copying operation is started by pressing the print key 56, the photosensitive drum As described above, a latent image corresponding to the original is formed on the document 3 as a result of exposure scanning. At this time, a part of the leading part of the latent image formed on one page is controlled to a blank paper potential by turning on the eraser 21,
Next, when the stylus passes over the first door 22, an electrostatic recording signal is applied to the first door 22 by the stylus from a control device (not shown), and an operation signal is placed on the blank potential portion of the photosensitive drum 3. A bar code mark as shown in FIG. 3 corresponding to the mode selected at 50 is recorded.

6. Next, when the transfer paper 13 is conveyed from the copying machine 1 to the sorter 2, the bar code mark recorded on the leading edge of the transfer paper 13 in this way is placed on the O
Read by MR38.

On the other hand, the sorter 2 of this embodiment includes a control device (hereinafter referred to as i A CPU (tentatively named CPU) is provided, and the output signal of the OMR 38 is applied to the C'PU.

Therefore, when the OMR 38 reads the barcode added to the transfer paper 13, the CPU (not shown) controls each drive unit based on the signal to eject the transfer paper 13 to a predetermined location.

For example, if you select the clear mode obtained by not pressing the mode selection key on the operation panel 50 or the interrupt mode obtained by pressing the interrupt key,
The leading edge of the transfer paper 13 is marked with "black, white, white" as shown in Figure 3.

3 is discharged to the sorter 2 side, and its code is OMR38.
When υ is read, the CPU on the sorter 2 side turns on the solenoid 41, switches the inlet switching guide plate 39 to the position shown in the dashed line, and discharges the transfer paper 13 onto the blueprint tray 42.

Similarly, when the stack mode or sort mode is selected by pressing the stack key 51 or sort key 52 on the operation panel 50, the leading edge of the transfer paper 13 discharged from the copying machine 1 is shown in FIG. "White, white, black"
Alternatively, a "white, black, white" barcode mark is recorded.

As a result, on the sorter 2 side, when the 0M838 reads the "white, black, white" barcode, it is determined that it is in the sorting mode, and when the transfer paper 13 is conveyed for the first time, all the deflection claws 3

1 to be discharged. Next, when the rear end of this transfer paper 13 passes the entry sensor 36, this is detected, and the deflection claw 33 provided at the entrance of the second bin 34-2 is deflected, and the next transfer paper 13 is It is discharged into the second bin 34-2. At this time as well, the passage of the trailing edge of the transfer paper 13 is detected by the entry sensor 36, and the CPU returns the deflecting claw 33 to its original non-deflecting position and at the same time deflects the next deflecting claw 33. Thereafter, the transfer paper 13 is sequentially discharged from the first bin in the same manner.

On the other hand, on the copying machine 1 side, the CPU, tυ
Applying a repeat end signal to one end 22 of the stylus,
A "black, black, white" code shown in FIG. 3 is recorded on the leading edge of the transfer paper 13.

When the sorter detects this code, this transcription i
When it is recognized that the transfer paper 13 is a repeat end copy and the transfer paper 13 is discharged into a predetermined bin 34, the copying operation of the number frame for the first document is once completed. Next, when the print key 56 is pressed again, the above operation is repeated, and the operation of discharging the transfer sheets 13 for the second document into each bin in turn is repeated.

On the other hand, in the stack mode, the sorter 2 reads the "white, white, black" code and then discharges the transfer paper 13 into the same bin until the 9-beat end code is read. When you read the repeat end code,
The deflection claw 3 at the entrance of the bin corresponds to the output of the entry sensor 36 detected as the transfer paper 13 is discharged into the bin.
3 to the non-deflected position, and also deflects the deflecting claw 33 at the entrance of the next bin, thereby performing the operation in the system stack mode.

While operating in the above sort mode or stack mode,
If a jam occurs on the sorter 2 side, this is detected by the outputs from the entry sensor 36 and the jam sensor 37, and the solenoid 41 is turned ONL, and the inlet switching guide plate 39 is switched to the position shown in the dashed line. For this, copy machine 1
The transfer paper 13 discharged from the transfer paper 13 is discharged onto the bruft tray 42 after a sorter jam occurs. On the other hand, copying machine 111
If a germ occurs in 'ilj, the germ is removed and the current mode is maintained until the next transfer paper 13 is detected on the sorter 2 side.

Figure 4 shows Stanno! as a post-processing device. Fig. 10 shows a configuration diagram of a copying apparatus according to an embodiment of the present invention when using -. In the figure, the same reference numerals as in FIG. 1 indicate the same parts, and 60 is a stun gun. This Stan i!
The inlet side of the -60 is also configured in the same way as the sorter 2, and includes an OMR 38 for reading the barcode recorded on the transfer paper 13, an inlet switching guide plate 39 for discharging the transfer paper 13 to the draft tray 42 as necessary, etc. It is provided. 6
1 is a stamping drum, on the surface of which there are stamps A62 and B6.
3 is installed. 64 is an ink roller, 65 is a pressure roller for stamping, and 66 is a paper discharge tray.

FIG. 5 shows the operation/operation provided on the copying machine 1 side of the copying machine
A configuration diagram of the four channels 70 is shown, in which 71 is a stamp A selection key, 72 is a stamp B selection key, 73 is an interrupt key, 74 is a numeric key, 75 is a clear key, and 76 is a print key.

With the above configuration, the stamp A selection key 7 on the operation/main panel 70
Press 1 or Stamp BA selection - 2, then press number key 7
When the number of sheets to be printed is selected in step 4 and the cylinder key 76 is pressed, the copying machine 1 starts the copying operation. At this time, in the same way as described above, the leading edge of the transfer paper 13 is marked with "white, black, white" corresponding to the stamp A or stamp B shown in FIG.
A parable code or "white, white, black" barcode mark is recorded.

When this mark is detected by the OMR38 on the Stan/4'-5Q side, is it Stanno? The CPU in -60 rotates the stamp drum 61 and causes the stamp A 62 or stamp B 63 corresponding to the mark to stand by at a predetermined position. Next, the conveyance roller 30 is moved from the entrance switching guide plate 39 located at the solid line position shown in the figure.
The stamping drum 61 is synchronized with the transfer paper 13 conveyed through the
Rotate. Thereby, the transfer paper 13 is ejected to the paper ejection tray 66 with a predetermined mark attached at a predetermined position.

On the other hand, if the selection keys 71 and 72 on the operation panel 70 are not pressed, or if the interrupt key 73 is pressed, the leading edge of the transfer paper 13 is marked with "black, white, white" as shown in FIG. A barcode mark is recorded.

As a result of this being read by the OMR 38 on the stamper 60 side, the solenoid 41 is turned on and the inlet switching guide plate 39 is turned on.
is switched to the position shown by the dashed dot line in the figure.

As a result, the transfer paper 13 discharged from the copying machine is discharged onto the bruft tray 42 at this time.

This operation is also performed when the jam sensor 37 detects a jam in the system stamper 60.

As mentioned above, sorter 2 and Stanno 9-60 are used as post-processing devices.
As can be seen by comparing the two copying machines shown in Figure 1 and Figure 4, Figure 2 and Figure 5, and Figure 3, it is clear that Machine 1
There is no need to change the mechanical part of the machine, regardless of what post-processing device is used. Furthermore, the operation/IP panel portion can be manufactured in the same way by simply changing the display surface. Furthermore, as is clear from FIG. 3, the signals generated from the corresponding keys in the operation/9 channel 50 and the operation/mother channel 70 are exactly the same, so the CPU on the copying machine 1 side is also common regardless of the post-processing device. It can be done. As a result, the copying machine can have the same configuration regardless of the post-processing device, so the manufacturing cost of this type of copying machine can be significantly reduced.

Furthermore, it is advantageous that there is no need to lay a signal line from the copying machine 1 to the post-processing device 13--and there is no need for interfaces found in conventional devices such as photocasolers, which also provides a great economical effect. Furthermore, since control signals are transmitted from the copying machine 1 to the post-processing device using barcode marks recorded on the transfer paper 13, it goes without saying that signal transmission is extremely stable against noise. can get.

In the above embodiment, an example was explained in which the sorter 2 and the stamper 60 are connected to the copying machine 1 as post-processing devices, but the present invention is not limited to this, and the present invention is not limited to this. The above-mentioned effects can be obtained using any post-processing device such as a folding machine.

In addition, in each of the above embodiments, in order to attach a code mark,
An eraser 21 is provided on the upstream side of the stylus door 22 around the photosensitive drum 3, but instead of providing the eraser 21, a portion of the contact glass 7 is erased by baking white paint in advance. Moyo 14- Yes.

Historically, in each of the above-mentioned embodiments, the exposure scanning light of the document is directly irradiated onto the photosensitive drum 3 to form continuous images, so the eraser 21, stylus? However, in the case of a digital copying machine such as a laser printer that converts electrical signals into laser beams and continuously images them on a photoreceptor, it is extremely difficult to add code marks by processing electrical signals. Easy to do, eraser 21, stylus gate 2
2 becomes unnecessary.

〔effect〕

As described above, according to the present invention, the copying machine attaches a predetermined code mark to the copy corresponding to the processing at that time, while the post-processing side reads the code mark and executes the corresponding post-processing. Therefore, even if the post-processing device is different, it can be handled by simply changing the operation panel on the copying machine side, and the changes in the configuration can be kept to a minimum, making it economical and easy to use. As a result, there is no electrical connection between the printer and the post-processing device, resulting in a highly reliable copying device with excellent noise resistance.
