Description

[Detailed description of the invention] The present invention relates to a recording device having folding means.

2. Description of the Related Art In recent years, a recording apparatus has been proposed which includes a folding means and which folds and discharges a recorded recording material. Some of these devices command the folding operation using a manual key or the like. In such a case, if the Fold 9 command is canceled by mistake before the recording operation is completed.

Recording materials that have not been folded are mixed in with recording materials that have been folded, and it becomes necessary to fold all of the recording materials that have not been folded, which causes trouble to the operator. was.

The present invention has been made in view of the above points, and includes: a self-recording means for recording an image on a recording material; an input means for inputting the total number of sheets to be repeatedly recorded; a folding means for folding the recorded recording material discharged from the recording means; The present invention provides a recording apparatus characterized in that it has a control means that makes it possible to clear the contents of the holding means after the recording operation for the number of recording sheets inputted by the fold 9 input means is completed.

First, an example of a copying machine to which the present invention is applied will be explained.

This copying machine is a powder development transfer type close-up copying machine.

The manuscript to be copied must be in sheet form, such as Class '4i.

The structure is such that it can easily copy all sorts of things, including thick manuscripts such as books.

In FIGS. 1 and 2, 1 is a machine box, 2 is a document table on which a document is placed, and has automatic document feed means 3.

4. 42 are transfer sheets 51 and 52f of different sizes,
This is a cassette for storing the paper, and 6 is a tray on which the transfer paper discharged from the machine after the transfer is placed. In Figure 2, 7 is the main switch, and 8 is the warning display section.

9. 92 is a cassette selection button, 10 is a paper size display section, 11 is a dial for adjusting copy density, 12 is a continuous copy number selection key, 13 is a continuous copy button linked thereto,
Reference numeral 14 indicates a single copy button that does not operate in conjunction, 15 indicates a stop button for canceling continuous copying, and 101 indicates a fold designation switch. A hopper is located at the front right side where the door is open to store replenishment developer and send it out as needed.

The operation of this copying machine will be explained with reference to FIG. The automatic document feeder 5 feeds only one sheet of a large number of sheets and documents placed on a tray (not shown) onto the glass 16. When fIJl to be copied and the leading edge of the document coincide with the leading edge of the crow 16 on the original crow 16, the p feeding means 13 is stopped by a switch that detects the fIJl. Next, when the copy button 13 or 14 is pressed, the photosensitive drum 17 starts rotating clockwise in the figure. When the photosensitive drum 17 reaches a predetermined position and a signal to start exposure is issued, the illumination lamp 18 and the first mirror 19, which are the movable parts of the optical system, move toward the photosensitive drum 1.
The second mirror 20 starts moving rightward in the drawing at the same speed as the circumferential speed of No. 7, and the second mirror 20 also starts moving rightward in the drawing at the same speed. One image of the document illuminated from below by the illumination lamp 1B is the g1 mirror 19. Second mirror 20. Lens 21. Third mirror 22. An optical system including the fourth mirror 23 forms an image on the photosensitive drum 17 at the exposure section 24 . When the exposure is completed, the optical system moving part detects its position, stops moving to the right, and immediately returns to the opposite direction, that is, to the left. This return speed should be faster than the forward speed.

Improves copying efficiency. Then, when it returns to the initial position, the drive to the optical system movable part is cut off and it stops.

If a large number of copies are to be made continuously from the same document, an arbitrary number of copies may be specified using the continuous copy number selection key 12, and the copying process may be started using the continuous copy button 15. Furthermore, if the copy is started using the one-copy button 14, only one copy can be made regardless of the number of copies specified by the number-of-copies selection key 12.

The photosensitive drum 17 has a six-layer structure in which a photosensitive layer on a conductive substrate is covered with a transparent insulating layer.

Rotate clockwise. The drum 17 is first charged by a positive charger 261C, which is supplied with a high voltage current e from a high voltage power source. Then, when reaching the exposure section 24,
At the same time that the original image mentioned above is exposed to slit light, high-pressure i
AC charger 27 that is supplied with AC high voltage current from zm
Receive JAOi electricity (static charge removal). Then, by the next full-face exposure step 28,
An electrostatic latent image is formed on the surface of the photosensitive drum 17.

It enters the developing device 29. In the developing device 29, the carrier on the sleeve 51 rotating around the magnet 30 comes into contact with a magnetic brush made of toner, so that the electrostatic charge 11F1# on the photosensitive drum 17 is developed and visualized. Next, the transfer paper 5 sent from the paper feed section is placed on the photosensitive drum 17, and the transfer charger 32 conducts electricity with high voltage current from the high voltage power source 35, so that the developed image on the photosensitive drum 17 is transferred to the transfer paper. 5. The transfer paper 5 coated with the transfer gold layer is separated from the photosensitive drum 17 by being restrained at one end by a one-separation belt and guided to the fixing device 34. The remaining toner 36 on the photosensitive drum is carried out of the area of the photosensitive drum 17 on the near side in the drawing at the edge portion 551 of the cleaning grade 65 that is pressed against it, and is led to the developing device 29 by a reuse duct and used again for development.

hx photo paper 5 t is cassette 4. The transfer paper 52 is stored in each cassette 42 and placed in the paper feed section 5 at the lower left of the machine.
B4. 582 in a removable manner. Various cassettes are available for different sizes of transfer paper, and can be easily replaced as needed. Selection of paper feed from the paper feed section 381 or 582 can be made using the cassette selection button 91.9□ on the front of the machine. When the photosensitive drum 17 reaches a predetermined position and issues a paper feed signal, the paper feed roller 391 or 39□ feeds the transfer paper 5.
1 or 5□ is sent out to the right in the drawing. Next, the second register roller 42. ．． 41, 40□, 412 prevents skewing and sends the paper in the correct direction. Then the second
After the register rollers 42 and 45 synchronize with the image on the photosensitive drum 1 using signals from the movable part of the optical system, the transfer paper 5 is brought into close contact with the photosensitive drum 17 and the image is transferred thereon, as described above. The transfer paper, which has been peeled off from the photosensitive drum 17 by the one-separation belt, enters the fixing device 34 as a primary step. In the fixing device 54, the unfixed image t- When the transfer paper 5 held on the garment surface passes through and is heated, the toner is thermally fused and one image is fixed on the transfer paper 5. The transfer paper 5 that has left the fixing device 34 is finally passed through the static eliminator 49! After removing the charge remaining on the surface of l1, it is discharged onto the guide plate 103 of the folding device 9 by the discharge rows 250, 51.

The photosensitive drum 17 of this copying machine is capable of copying up to the width of an A5 sheet, and its outer circumference is somewhat longer than the length of an A5 sheet. On the other hand, after the forward movement (exposure stroke) of the optical system movable part, double movement is required for approximately the same time as the forward movement. Therefore, in the case of i-copying, one sheet is transferred per two rotations of the photosensitive drum, and in the case of A4 copying, one sheet is transferred per one rotation of the photosensitive drum when the transfer paper is fed horizontally (in a direction perpendicular to the longitudinal direction). The difference in the cycle depending on the paper size as described above is that the cassette 41 selected by the cassette selection buttons 91, 9□
or 42, and controls the amount of movement of the optical system movable section.

After the copying operation is completed, the trailing edge of the transfer paper 5.

After passing through the discharge rollers 50 and 51, the photosensitive drum 17 stops. At this time, in order to prevent the cleaning blade 35 from being in constant pressure contact with the surface of the photosensitive drum 17, which may affect the image, the edge portion of the cleaning blade 35 is placed near the seam of the photosensitive layer, that is, the area where one image does not appear. The photosensitive drum 17 stops at a position where the angle is +5°.

Note that the blade 65 can be separated from the drum surface when the drum is stopped, if necessary.

As an example, a case will be described below in which A4 size transfer paper 5 is stored in the cassette 41 and A5 size transfer paper 52 is stored in the cassette 4□.

By using the fold selection switch 101, when A3 size paper is designated to be folded in two, two A6 paper sheets 52 are set aside, and the other sizes are ejected as is.

That is, the A4 transfer paper 51 discharged by the discharge rollers 51 and 52 of the copying machine main body is guided by the guide plate 103,
It is sent upward by the feed roller 102 and the conveyor belt 1o4, and by the holding roller group 105.

It is guided by the roller 106' (the position where the row 2106 has been moved) and is sent directly to the rollers 108 and 107.

It is discharged to tray B.

On the other hand, when the transfer paper 52 was A6, it was ejected by the ejection rows 251 and 52 of the copying machine main body. The transfer paper 5□ is guided by a guide plate 106, sent upward by a feed roller 102 and a conveyance bell) 104, and is sent to rollers 1 o 6 o 107 by a group of holding rollers 105, and is transferred to a roller 1 o 6 o 107.
09, hits the stopper 110, and is folded by the folding rollers 108 and 107.

It is folded and discharged onto the tray 6.

The operation of the folding roller will be explained with reference to FIG.

Rollers 106 and 106' are identical and lever 113
The lever is pivotally supported by a shaft 112.

Due to the plunger on/off operation, the stopper 117.1
1 (hitting S, roller 1o6 is 106 and 106'
Two positions are possible, and it can be folded or not folded.

The means for moving the mouth 106 to the position 106' is rotatably supported by a rotary support shaft 112...-116, the Ronia 106 is rotatably supported thereto, and the lever 113 is activated when the plunger 111 is off At this time, the blade of the spring 114 suspended on the lever 115 stops at the stopper 116, and the roller comes to the position 106'. This allows the transfer paper 5 to be discharged without folding. Also, when the plunger 111 is on, the lever 113 stops at the stopper 117 and brings the roller to the position 106, thereby folding the paper and ejecting it.

The respective state diagrams are shown in Figures 4 and 5. That is, when the feeding roller 106 is in the position shown in FIG. The folded portion 53 is then sandwiched between the folding sheet 108 and the feed roller 107 and fed.

As a result, the transfer paper is folded according to the length of the blade 109 and sent.

Of course, if the length of each blade 109 is changed, it can be folded to the corresponding length.

Further, when the feeding roller 106 is in the state shown in FIG.
8 and 107 and is discharged.

In this case, it is effective to ensure that the liquid is ejected using the guide 118 or the like.

FIG. 6 shows a control circuit for executing the above-mentioned folding process, and FIG. 8 shows an input/output time chart of the circuit. In FIG. 6, OPB is the copy start button 15. i4 (

It outputs pulses for B, D, and F.

The 5TAT signal first rotates the drum once to clean its surface, equalize the sensitivity of the photoreceptor, and then starts the optical system to move forward. In Fig. 8, PF is a signal for feeding paper from all transfer paper cassettes and is output by a cam installed on the drum.
7).

FIG. 8 is a time chart when two copies are made for each original sent from the automatic document feeder (hereinafter referred to as ADF) to the original table. First, at point (3), the operator fully presses the copy button fc, which indicates that there is no operation because no ADF K original is set. At point ■, the operator has set the document; at point 2, the fold switch s is pressed to further fold and store the cobby paper.
1 is turned on.

At (2), when the operator presses the copy button again, the copy conditions are met, so the document feed motor is driven and one document is fed onto the document table. There are two cases regarding the timing to set the document feed p motor. It is represented by ■ and ■. The case represented by (2) is a signal input to AND gate B 1, and the case represented by (7) is a signal input to AND gate B 2. AND gate B has the logic that when an L level signal is input to either 1 or 2, it outputs the full L level signal and sets flip-flop R8F1.
R8F1 is set in either case.

Therefore, in the case of ■, the logic is assembled in Nant gate A, so when the original remaining amount detection switch ORP is set to [Yes], the document platen stop position switch is set to [Phase], and the copy button is turned on, , Nando game) A input 1.2
j all go to H level, p output goes to L level, and R8F
1 is set. On the other hand, in the case represented by ■, R8Fl must be set by the falling edge of OPB.
Therefore, the differentiating circuit D is set by the output Q of RF2.
Drive A.

(AND GO) Input a differential pulse of 7'cL level to the 2 terminals of B according to the falling ρ of Q of R8F2, and set R8Fi.

Next, ■ indicates that the leading edge of the document sent to the document table has reached the proper position and the document stop position switch is fully activated. As a result, the document feed motor is stopped and the document is stopped on the document table. Furthermore.

Based on the result of this stop, the copy signal 5TART is turned on and the main body of the copying machine is moved by km. Simultaneously with this driving, the folding solenoid 5OL111 is excited in response to the operator's instruction in (2).

2 indicates that the post-rotation cycle is entered and a coincidence signal C0IN between the number of sheets set by the operator and the number of copies per copy is generated. In ■, it indicates that the photosensitive drum in the copying device has reached the stop position [DHP] when the CON signal is generated, and when these two conditions are met, the copying device is stopped, so the copying signal is Turn it off completely. Further, due to this stop, the document feed motor P is driven again to eject the document on the document table and send out a new document to the document table. ■ indicates that the document that had been on the document table until then has been completely ejected to the outside of the document table. Furthermore, a timer is set by this discharge signal, and this is to turn off the document feed motor at the falling edge of the timer signal T if there is no subsequent document when the timer time elapses. 2 indicates that the second document reached the appropriate position on the document table within the time period during which the timer was not turned off, and the switch at the document table stop position was activated.

Historically, this causes the original feed motor to be turned off as in case (2), and by turning it off, the copy signal 5TART that drives the main body of the copying apparatus is fully turned on.

Also, since the operator's instruction of the folding switch SW1 remains the same, the folding solenoid 5OL111 continues to be excited. Then, the copy cycle is repeated in the same way. 0, even though the operator switched the folding switch and cassette V from the upper tier (full size) to the lower tier (berm size) during the copy cycle for the second document, the folding solenoid 111 in the folding device immediately indicates not responding. In ■, when the second original is ejected from the original table, the third and final original is fed from the original tray, and the remaining original amount detection switch is turned on and the original is placed in the original tray. This indicates that the manuscript is no longer available. ■Now■
, and ■ operate in the same way as ■, but in ■, the operator switches all the folding switches fc, and the folding solenoid 111
is turned off. 0 indicates that the document feed motor is turned off and all operations are stopped because no document appears even after the timer time has elapsed after the third and final document was discharged.

There are two cases regarding the timing at which the document feed motor is reset. It is represented by ■ and O. The case represented by ■ is a signal input to 1 of AND gate D, and O
The case represented by is one word input to AND gate D 2. ANDKATE D outputs an L level signal when an L level signal is input to either 1 or 2, and R8l1
Since the logic is to reset '1, R8Fi is reset in the case represented by either ■ or 0. Therefore, in the case of ■, the moment the document platen stop position switch becomes [ON].

When inverter C changes from H level to L level, inverter C drives differentiator circuit Bi, and AND gate D's 1
A differential pulse of L level is generated at the terminal to reset R8Fi.

On the other hand, in case @, when the document platen stop position switch changes from [Yes] to [Phase], that is, the timer input is H.
A timer is set when switching from level to L level. Then, at the moment when the timer is reset, that is, H
When the level changes from the level to the L level, the differential circuit C is driven by the differential circuit C, and a differential pulse of the L level is applied to the two terminals of AND-GATllfD, and R8Fj'i is reset.

The case where the copy signal R8F2 is set is represented by ■. Since R13F2 is set at the falling edge of the document feed p motor signal, in FIG. The differential pulse of L v Her is input to the inverter F, inverted, and the differential pulse of H level is input to the two terminals of the Nandt gate. Here, the reason why Nandokate E is provided and the document platen stop position signal is input to the 1st terminal is that R8F2 is set only when the document platen stop position switch is set to [Yes], and in the case of 0,
This is to prevent R8F2 from being set when the switch is set to [stock]. Therefore, the switch is [
Nant gate E opens only when the differential pulse is generated, and R8F 2 is set when a differential pulse is generated.

The case where the copy signal RBF 2 e is reset is represented by the case (2). This is when the coincidence signal is 5fflT and the drum stop position switch is set to ``present'', so these signals are input to gates 1 and 2 of gate G to assemble the logic.

Now, consider the relationship between the operator's switching of the folding p switch and the time the copy paper reaches the folding device 106'.

As is clear from the above description, no matter what time the operator switches the switch, the solenoid 111 responds only at the rising edge of the copying signal 5TAT, that is, when the copying machine starts the copying operation. As is clear from the time chart, the last copy sheet for each original is folded by the Q roller 106'.
Since the time point b' when the copy sheet reaches the document table is within the time when the primary document table ADF is feeding the document sheet to the document table, the copy paper is folded in the folding device.
There will be no inconvenience such as switching of the folding solenoid 111 at any time during work.

The timing at which the folding thinneroid 111 turns on and off is when the operator selects the full size cassette lr with the upper/lower cassette selection switch and specifies the "fold" instruction with the folding switch, and the moment the copy signal is set. This is a meeting of Therefore, this condition (when folding with a full size cassette) is made up of two parts: the logic that makes up the entire configuration, and the logic that controls the on/off of the folding solenoid 111 at the rising edge of the copy signal.

In Figure 6, MSi to MS3 are upper cassette size selection switches; M51' to MB5' are lower cassette size selection switches. Now A5. B4. Make it so that it fits in the U1 size. These six switches are input to the selector circuit J, and on the other hand, the signal of the upper/lower selection switch is input to the selector. Therefore.

When you specify ■ with the up/down switch, MSi~MS
Each of the 3 signals is output to the 1, 2, and 4 terminals of the selector. Similarly, when specifying ■, MS1' to MS3'
The signals are output to the selector 1, 2.4 terminals. Here, as is clear from Figure 7, in the case of full size, MS5
Alternatively, since MS 3' is off (OFF'), an H level signal appears at the 4 terminals of the selector. The four terminals of this selector and the signal from the folding switch are input to AND gate H to configure the former logic. The latter logic converts the output of the ANDG)H to JKF
1's J terminal, given opposite logic levels to the terminal.

The p-coupling is performed by controlling the copy signal 5TAT as a clock input. Hence this result.

Even if the operator turns off the switches at any time, there is no immediate response, but a response occurs when the copying machine starts copying.

In addition, U, U2 in FIG. 7 are universal size type cassettes that can be set to various sizes, and the size of U2 corresponds to half of U1.
