Abstract

PURPOSE:To automatize end surface folding processing capable of providing a proper folded line by pressing a sheet with a push plate adapted to reciprocate and move vertically while folding a corner part of the sheet into a triangular shape with use of the reciprocating push plate. CONSTITUTION:A paper sheet fed into between rollers 116 and 118 is adapted to pass through between a folding plate 197 and a push plate 138. Thereupon, conducted a current through a solenoid 150, the whole of the push plate 138 is more lowered than the upper surface of the folding plate 197 since a roller 152 strongly presses an arm 140, for pushing the paper sheet. Then, conducted a current through a half-rotation clutch 136, the folding plate 197 is moved to the right and allowed to fold the sheet when getting over the push plate 138. In succession, moved the push plate 197 to the right, a carriage 198 is allowed to push an arm tip end 195 to the right, and to move also the push plate 138 to the right to permit the arm 140 to be disconnected from the roller 152 to the right, whereby the arm 140 is prevented from returning to the left owing to the roller 152. And, interrupted the current to the half-rotation clutch 136, the folding plate 197 is allowed to return to a waiting position, and in succession interrupted the current to the solenoid 150, the push plate 138 becomes a waiting state for automatizing end surface folding.

Description

DETAILED DESCRIPTION OF THE INVENTION ■Technical Field The present invention relates to a sheet folding device, and in particular to a single blade folding device.
The corner part that overlaps the binding edge of the file is
This invention relates to an end face folding device that folds into a square shape.

■Prior Art For example, copies of various sizes can be obtained using conventionally used blueprints (diazo copies) and recent electrophotographs (transfer type copies).

Generally, A-size copies larger than A4 should be folded into A4, and B-size copies larger than B5 should be folded into B.
Fold into 5. For example, when folding A2 to A4, first fold one corner into a triangular shape (end face folding), then fold once vertically, and then fold twice horizontally (wing folding).

Conventionally, this type of sheet folding process is performed manually, which requires a lot of work, and it is not always possible to obtain an accurate folded shape. Many people do not know the folding method, and it takes time and effort to correct the hanging method.

(1) Purpose The first object of the present invention is to provide an end folding device that automatically performs end folding, and the second object is to provide an end folding device that can obtain accurate folding lines.

■Structure and ■Effects In order to achieve the above objects, the present invention includes: a folded plate that moves back and forth; a push plate that moves back and forth and up and down; a first drive mechanism that drives the folded plate back and forth; a first drive mechanism that drives the push plate back and forth; 2 drive mechanism;
It shall be provided with a third drive mechanism that drives the push plate up and down; and a control means that biases the first drive mechanism after biasing the third drive mechanism. That is, the pushing plate is driven downward to press the sheet, and the folding plate is driven forward to fold the corner portion of the sheet into a triangular shape.

According to this, since the sheet is held down and the folding position is defined by the press plate, triangular folding is reliably performed and the folding line is accurate.

In a preferred embodiment of the invention, the folded plates are placed at two corners of the paper.
It has a "C" shaped flat surface with a straight part on which the sides rest, and a curved part that is continuous with the straight part and bends one side of the paper raised in the straight part. The edge has a knife for guiding the paper downward, and the first drive mechanism for reciprocating the folded plate is a link arm and a half-rotation clutch connected to the folded plate via the link arm, The second drive mechanism that reciprocates is composed of a spring member that provides a return force in the direction of the standby position and an interlocking member that is pushed by the forward movement of the folded plate to move the push plate in the same direction, and drives the push plate up and down. The third drive mechanism is composed of a solenoid and a member that is driven by the solenoid and drives the push plate downward.

According to this, with the seat stationary at a predetermined position,
The "C"-shaped straight part of the folded plate raises the corner part of the sheet, and the curved part bends the sheet, and the pressing plate presses the sheet downward during such bending of the sheet to fix the sheet. Accurate end folding can be performed with a relatively small number of mechanical elements and without complicated movement of the sheet.

Other objects and features of the invention will become apparent from the following description of preferred embodiments with reference to the drawings.

〔Example〕

In the first part, a sheet processing machine 900 according to an embodiment is shown with the openable and closable front cover removed.

Note that this sheet processing machine 900 has an appearance shown in FIG. 2 when the front cover is closed, and in the most preferable embodiment, as shown in FIG.
A control signal line of the sheet processing machine 900 is connected to the copying machine 800. A control signal line for sorter 1000 is also connected to copying machine 800.

The copying machine 800 is designed to be most suitable for this combination mode, and the copy size (recording paper size) 9 copies, copy feeding orientation (vertical, horizontal), stamp data (stamp necessity, stamp position 2) Publisher 1 drawing type), punch data (punch required or not).

Sheet discharge data (sheet discharge to tray ET or sheet discharge to sorter 1000), start signal, end signal, etc. are given to sheet processing machine 900.

The sheet processing machine 900 is equipped with an operation board 11 that allows input paper size, paper orientation (vertical, horizontal), and stamp data (necessity of stamping) to be displayed.

l It is now possible to set or input stamp position 2 (publisher 2 drawing types), punch data (necessity of punching), paper ejection data (ejection to tray ET or ejection to sorter 1000), start signal, etc. The copying machine 800 can operate independently of the copying machine 800 in response to settings on the operation board 11 and operations on the board 11. When a certain signal is received from the copying machine 800, the sheet processing machine 9
00 takes up the data and signals received from the copying machine 800 with priority over the settings and operations of the operation board 11.

When copying machine 800 does not provide the required data, sheet processing machine 900 operates according to the settings and/or operations of operation board 11.

Referring again to FIG. Copy paper is supplied from a copying machine 800 to a sheet processing machine 900 in the direction of an arrow 801. Note that when the copying machine 800 is not connected, paper is fed to the sheet processing machine 900 from the direction of the arrow 801 using an auto feeder or manual feeding.

A drawer-shaped case is pulled out from the main body of the sheet processing machine 900 toward the front.

A power fiber connector and a signal fiber connector, which are connected to the power line female connector and signal line female connector of the sheet processing machine 900 main body, are also fixed to the case wall on the back side of the drawer-shaped case that houses each unit. These male connectors engage the female connectors when the engagers engage the latch members.

Roughly speaking, the gear that obtains the main power of the mechanical unit is exposed behind the case wall on the back side of the drawer-shaped case that houses each unit, and the aforementioned engager engages with the latch member. When this gear is in the main body of the sheet processing machine 900,
It engages with the gears of the power transmission system driven by the main motor. The gear that obtains the main power of the mechanism unit is pivotally mounted to a drawer-shaped case, and the gear shaft is connected to the gear via another gear.

Further, a paper conveyance roller of the mechanical unit is connected via power transmission means such as a chain or belt, and a clutch as necessary. Note that some mechanical units are equipped with an independent motor for driving rollers, and in this embodiment, in a mechanical unit with simple paper feed control, the rollers of the mechanical unit are connected to the main power system of the main body of the sheet processing machine 900 via gears. However, in mechanical units whose paper feeding control is somewhat complicated, an independent motor is provided in the drawer-shaped case so that the paper feeding rollers within one mechanism are independently driven by the motor.

Next, the configuration of each mechanical unit will be explained with reference to FIGS. 5a to 11.

First, with reference to FIG. 5a, the vertical folding mechanism unit p
The configuration of 100 will be explained.

The vertical folding mechanism unit 100 includes a paper entry roller 104 and a paper entry gate claw 112.3 that determines the feeding direction of the 1082 paper.
vertical folding rollers 116, 118° 120, vertical folding conveyance rollers 162, 166, and end folding folding plates 197. Equipped with registers 154, 156, etc. for setting vertical folding position,
The required rollers are coupled to a drive power system (not shown) of unit 100.

The paper entry gate claw 112 is fixed to the rotating shaft 110,
This rotating shaft 110 is rotationally driven by a solenoid 114. When vertical folding is not instructed, solenoid 114
In this case, the paper entry gate 112 is placed in the solid line position shown in the figure without being energized. In this state, the paper sent directly below the paper sensor 174 is received by the rollers 104 and 108, but the claw 1
Unit 2 hits the bottom surface of Unit 12 and is bent downward.
Go straight to 00. When vertical folding is instructed, when the sensor 174 detects paper, the solenoid 114 is energized and the tip of the claw 112 descends in the direction of the lower roller shaft 106 (shape S shown by a two-dot chain line in FIG. 4). . 'In this state, the paper sent directly below the sensor 174 is received by the rollers 104 and 108, rides on the upper surface of the claw 112, and is sent toward the vertical folding rollers 116 and 118°120.

Vertical folding rollers 120 and 118 are in contact, but roller 116 does not contact 120 in any state.

The vertical folding roller 116 is supported by a shaft 122 and is rotatable about the shaft. A plunger of a solenoid 124 is connected to the arm to which the roller 116 is pivoted, and when the solenoid 124 is energized, the roller 116 is
is separated from roller 118, and paper that has passed through the upper surface of pawl 112 can enter between rollers 118 and 116. When solenoid 124 is de-energized, roller 116 is
It is in pressure contact with 18.

The fixed register 178 is for positioning the short side of A2 when vertically folding, and the fixed register 154 is for positioning the short side of A2 when vertically folding A2/quarter-folding.
The movable register 126 for long side positioning is B3 during vertical folding.
The positioning of the short side and the movable register 156 are B3
・For positioning the 83 long sides when vertically folding into four.

Plungers of solenoids 130 and 160 are coupled to movable registers 126 and 156, respectively. When solenoid 130 is de-energized, register 12
6 is retracted from the vertical origami paper transport path. Solenoid 130
When the register 126 is energized, the register 126 advances into the longitudinal folding paper transport path and stops the incoming paper therein. Solenoid 160
When is not energized, the register 1, 56 is retracted from the vertical folding paper transport path. When solenoid 160 is energized,
A register 156 advances into the longitudinal folding paper transport path and stops the incoming paper therein.

Rollers 166 and 162 are connected to rollers 104 and 10 when solenoid 124 is energized and roller 116 is pulled up.
8 to feed the paper introduced through the upper surface of the pawl 112 to the register 178 or 126. After the leading edge of the paper is placed against register 178 or 126, solenoid 124 is de-energized and the paper is sandwiched between vertical folding rollers 116 and 118. In this state, the paper is sent toward the register 154 or 156 by these rollers 116 and 118, and when one side of the paper hits the register 154 or 156, the paper is deflected when it leaves between the rollers 116 and 118, and this deflection is The paper becomes larger and is caught between the rollers 118 and 120, folded in half vertically, and sent to the unit 200 through the delivery port (a slit-shaped opening parallel to the axis of the vertical folding rollers) directly below the rollers 118 and 120. A steel ball 169 is placed on the roller 166, and a steel ball solenoid 164 is placed opposite the roller 162 so that the rotation of the rollers 166 and 162 does not create resistance to the movement of the paper during such vertical folding. There is.

The steel ball 169 is supported by a ball support (not shown) so as to be rotatable in multiple directions, and is always in contact with the roller 166, and when paper arrives, it presses the paper against the roller 166 with its own weight,
Rotates as the paper moves. Therefore, when the paper is moving directly under the vertical folding roller 116 in the axial direction of the roller, the rotation of the roller 116 drives the paper in that direction. When the paper moves in a direction perpendicular to the axis of the longitudinal folding roller I116 (lengthwise folding in two), the steel ball 169 rotates as the paper moves, so it does not interfere with the movement of the paper.

The steel ball solenoid 164 has a structure in which an electric coil is wound around a magnetic core, and when the electric coil is energized, the steel ball 165 is attracted to the core and separated from the roller 162. Steel ball 1
65 has roughly the same effect on the paper as the steel ball 169, but when the paper is driven in a direction perpendicular to the axis of the vertical folding roller 116 (folding in two vertically), the steel ball 65 is activated by energizing the electric coil. 16
5 from the roller 162 (paper) and
reduce frictional resistance.

The folded plate 197 is fixed to the carriage 198.

This carriage 198 is the guide bar 134.

It is guided so as to be able to reciprocate in the direction of the arrow (the axial direction of the roller 116). The carriage 198 has a link arm 196
is pivotally connected to this link arm, and another link arm that is pivotally connected to this link arm is fixed to the output shaft of the half-rotation clutch 136. The gear fixed to the input shaft of the half-rotation clutch 136 is as follows.

It is engaged with a drive power system (not shown) of unit 100. When the half-rotation clutch 136 is energized, it rotates the link arm 196 half a turn clockwise to drive the carriage 199 (that is, the folded plate 197) to the right, and when the energization is cut off, the half-rotation clutch 136 rotates the link arm 196 in the opposite direction. The carriage 199 (that is, the folded plate 197) is driven to the left by making a half turn clockwise.

FIG. 5a shows the folded plate 197 in the standby position.

To the right of the folded plate 197 is a push plate 138. This push plate 13
8 is fixed to the U-shaped arm 140, and arm 1
40 is pivotally mounted to a carriage 142. The carriage 142 has a guide bar 193 parallel to the guide bar 199.
It is guided so that it can freely move back and forth. An arm 146 is fixed to the carriage 142, and the tip 1 of the arm 146 is fixed to the carriage 142.
95 projects into the path of the carriage 198. A roller 152 is in contact with the U-shaped arm 140,
This roller 152 is pivotally attached to one end of the rotating arm 148. A solenoid 15 is attached to the other end of the rotating arm 148.
0 plunger 150 is coupled. In the state shown in FIG. 5a (standby state), the U-shaped arm 140 is held loosely by the roller 152. The push plate 138, in which the U-shaped arm 140 is fixed to the U-shaped arm 140 in a dogleg shape, is lifted upward by a spring 145 (left pull) and a spring 144 (upward pull). . In this state, the paper fed between the rollers 116-118 passes through the space between the folding plate 197 and the pushing plate 138.

When the solenoid 150 is energized, the arm 148 rotates counterclockwise, and the roller 152 strongly presses the arm 140. As a result, the U-shaped arm 140 rotates counterclockwise, and the entire pressing plate 138 becomes lower than the upper surface of the folding plate 197, pressing the paper downward. When the half-rotation clutch 136 is energized in this state, the folding plate 197 moves to the right and bends the paper as it passes over the push plate 138. Folded plate 19
7 moves to the right to some extent, the carriage 198 pushes the tip 195 of the arm 146 to the right, which causes the push plate 1 to move to the right.
38 also moves to the right. When the U-shaped arm 140' comes off the roller 152 to the right, the roller 152 prevents the U-shaped arm 140 from returning to the left. If the half-rotation clutch 136 is de-energized in this state, the folded plate 197
returns to the standby position shown in Figure 5a. When the solenoid 150 is de-energized, the U-shaped arm 140 pushes up the roller 152 by the force of the spring 144, and as a result, the push plate 138 moves upward and to the left by the force of the spring 145, as shown in FIG. 5a. The system enters the standby state shown in .

Fig. 5b shows an enlarged plane of the folded plate 197, and Fig. 5c shows its v.
A cross section along the c-vc line is shown, and FIG. 5d shows a cross section along the VD-VD line. The edge of the folded plate 197 on the push plate 138 side is approximately knife-shaped with an inclined lower surface (dotted line),
It is designed so that it is easy to fold the wire (line) and hold it in your mouth. Further, the tip of the folded plate 197 has a substantially "C" shape to prevent the paper from escaping. When the A2 paper is positioned with the register 178 and the B3 paper is positioned with the register 126, one corner of the paper PR (double-dashed line) has a triangular shape as shown in Fig. 5b. The paper PR is placed on the folded plate 197 and is between the folded plate 197 and the push plate 138. This state is shown in FIG. 5e.

In this state, when the solenoid 150 is energized, the paper is pressed against a lower paper guide plate (not shown) by the press plate 138. When the half-turn clutch 136 is energized, the folding plate 197 moves to the right as shown in FIG. 5f, folding the corner of the paper over the push plate and the paper above it. Folded plate 197
As the paper progresses further, the push plate 138 also moves to the right, and the push plate 138 comes out of the folded portion of the paper to the right. When the half-rotation clutch 136 is de-energized, the folded plate 197 moves to the left as shown in Fig. 5g, and finally returns to the standby position (Fig. 5e). When the solenoid 150 is de-energized, the push plate 138 returns from the position shown in FIG. 5g to the standby position (FIG. 5e) by the force of the spring 146. At this time, the push plate 138 moves upward due to the action of the spring 144 and does not come into contact with the folded corner piece of the paper PR.

Although not shown, a fixed register 154 used for vertically folding in half for A2/4 folding and a movable register 156 used for vertically folding in 2's for 83/4 folding are parallel to The movable register (154J) and B3

In this vertical folding mechanism unit 100, the roller 108 is connected to the main power system (not shown) of the unit, and rotates during the room while the main power system is in motion.
66 and 118 and the half-rotation clutch 136 human power system are all selectively connected to the main power system through one clutch. The main power system starts moving in response to a start signal and stops when a predetermined condition is met. For example, when the end signal arrives or when the sensor 17
4 is stopped when a predetermined time has elapsed since the paper press was detected, or when a paper jam occurs. The clutch has three modes: A2/4-fold mode, A2/JIS fold mode, B3.
・It is energized when the 4-fold mode and the B3/JIS fold mode are set.

When a paper jam occurs while the unit 100 is in a state where the solenoid 114 is off), the roller 104 is separated from the roller 108 to remove the jammed paper. Vertical fold mode (Solenoid 1
14 on) and the jammed paper is caught in the vertical folding rollers 116, 118, and 120, it is difficult to remove it, so the roller shaft 170
By connecting a grip 180 to and rotating the grip 180, the rollers 162, 166 and the vertical folding roller 116 are rotated.
．． 118 and 120 are manually rotated.

Next, details of the operation of the vertical folding mechanism unit 100 will be explained with reference to FIG. 5a.

Operation of the structure unit 100 (1) A2/4-fold mode--When the sensor 174 detects paper, the solenoids 114 and 124 are energized. When the sensor 176 detects paper, the rotary encoder 297 (
The pulse count shown in Figure 6a) is started and the count value is 5.
When the timing value at which the entire leading edge of the paper comes into contact with the fixed register 178 is reached, the solenoid 124 is de-energized and the solenoid 164 is energized. When the sensor 176 does not detect paper (because the paper is already caught in the roller of the next unit 200), the solenoids 164 and 114
Cut off the electricity.

(2) A2/JIS folding mode - When the sensor 174 detects paper, the solenoids 114, 124 and 160AJ
(not shown) is energized. When the sensor 176 detects paper, the rotary encoder 297 (FIG. 6a) starts pulse counting, and when the count value reaches the timing value when the entire leading edge of the paper has come into contact with the fixed register 178,
The solenoid 124 is de-energized and the solenoid 164 is energized. When the sensor 176 does not detect paper (because the paper is already caught in the row seams of the next unit 200)

Four-fold mode--When sensor 174 detects paper, solenoids 114, 124, 130, and 160 are energized. When the sensor 176 detects paper, the rotary encoder 297 (Fig. 6a) starts pulse counting, and when the count value reaches the timing value at which the entire leading edge of one paper has come into contact with the movable register 26, the solenoid 124 is energized. The solenoid 164 is turned off and the solenoid 164 is energized. sensor 7
6 becomes non-detected (because the paper is already caught in the roller of the next unit 200), the solenoid 164,
130, 160 and 114 are de-energized.

(4) B3/JIS folding mode - When the sensor 74 detects paper, the solenoids 114, 124, 130 and 1
60BJ (not shown) is energized. When sensor 76 detects paper, rotary encoder 297 (Figure 6a)
pulse counting is started, and when the count value reaches a timing value at which the entire leading edge of one paper has come into contact with the movable register 26, the energization of the solenoid 124 is cut off and the energization of the solenoid 164 is started. When the sensor 76 detects no paper (
(Since the paper has already been caught in the rollers of the next unit 200), the power to the solenoids 164, 130° 160J and 114 is cut off.

(5) Modes other than the above--All solenoids are de-energized and rollers 104 and 108 are driven.

(6) In addition to this, normal paper jam detection and mechanism stop when a jam is detected.

FIG. 5h shows the structure of the mechanical section of another embodiment of the present invention. In this case, a lever (rotator) 98 is arranged below the guide bar 99, and one end of the lever 98 is pivotally connected to a fixing pin 97. A pin 99 is fixed to the other end of the lever 98, and this pin 99 connects to the arm 195.
is in contact with the side edge of The end folding operation by this mechanism is similar to that shown in FIG. 5a, but when the carriage 198 moves forward and the folding plate moves to the right, the carriage hits the lever 98 and the lever 98 moves clockwise. , and pushes the arm 195 to the right, thereby pushing the push plate 138
moves to the right, but since carriage 198 pushes lever 98 between pins 97 and 99, carriage 198 moves to the right.
The push plate 138 moves to the right at a speed faster than the rightward movement speed of , and escapes from below the folded plate 197 to the right. Like this 1
In this example, when the folded plate 197 moves to the right to some extent, the push plate 138 escapes to the right at a high speed and retreats to the right of the folded plate 197. At the same time as the half-clutch 136 is de-energized, the solenoid 150 is also de-energized, the folding plate 197 returns to the left, the push plate 138 rotates upward, and returns to the left by the force of the spring 145. In this example, when the end face folding is completed (the folding plate 197 moves to the rightmost side).

The push plate 138 is retracted to the right to a greater extent than the folded plate 197 and the triangularly folded paper, and the push plate 138 rises from a position sufficiently away from the triangular origami and returns to the left.

There is sufficient margin for the retracting operation of the push plate 138.

7a to 7d show the control operation of the microprocessor 4 of the operation board control unit 10. With reference to these drawings, the control operation of the operation board control unit 10, that is, the control operation of the microprocessor 4 will be explained. Explain.

Referring first to FIG. 7a. When the power is turned on, the microprocessor (hereinafter simply referred to as CPU) 14 initializes the input/output board, registers for temporary data storage, status registers (flags), and counters (program counters).
, timer (program timer), etc. (step 1). In the following, the word "step" will be omitted in parentheses, and only the step symbol will be shown.

After completing the initialization, the CPU 14 reads the status. First, it is checked whether there is a read flag (2
). At this point, we have just finished initializing, so there is no read flag.

Proceed to step 3 and set standard data in the operation board register. Standard data is: Paper size: A4 Digit selection: Unfolded portrait/horizontal orientation: Landscape Stamp position: Om+a Publisher:
1st design (1st publication year) Drawing type: Temporary drawing (1st drawing type) Punch selection: No punch paper ejection selection Turn on the light. In this state, on the operation board 12, standby (this is set at initialization),
A4. No folds, horizontal, Omm, no punch, 1st design,
Indicator lights indicating each of the tray and temporary drawing are lit.

In Figure 6b, 3 assigned to the operating board register OBR
Byte memory area (an area of the internal RAM of the CPU 14)
Indicates the writing position of data to be temporarily written to.

When the standard data is written to the operation board register OBR, a read flag is set.
Determine whether or not a signal is transmitted from 0 (5). If there is transmission, receive it, read the signal and data, and determine whether the signal is a start signal (6). If it is not a start signal, it is an end signal. 7) If it is not an end signal, it is data, so among the input data, the data for which memory bits are assigned to the operation board register OBR should be written as OBR update to the operation board register. When an update is written, the operation board register OB
Write 1 to the bit indicated as the copying machine input bit of R. This one is.

This indicates that the copying machine 800 has given an instruction to the sheet processing machine 900 regarding sheet processing. Although not shown, the CPU 14 stores in its memory data received from the copying machine and indicating what has been written to the operation board register OBR (indicating what the written data is). When data is received from the copying machine 800 and writing to the operation board register OBR is completed and the process proceeds to step 9, or if there is no input from the copying machine 800,
Proceeding from step 5 to step 9, in this step the key-in on the operation board 12 is read, and if the key-in is from the key switches 12a to 12e (10), the copier input bit is referred to and if it is not 1 (copy (11) The contents of the operation register are updated according to the key-in, and the indicator light on the operation board is turned on.

Update Off to match this update. For example, when the switch 12a is closed, the size designation bit of the operation board register OBR is updated to data indicating the next 83 of A4 at the moment it is closed, and the indicator light of A4 is turned off and the indicator light of B3 is turned on. do. When the key switch 12a is closed once when the size designation bit of the operation board register OBH is 85, the size designation bit is updated to data indicating A2, the B5 indicator light is turned off, and the A2 indicator light is turned off. lights up. In this way, each time the size indication key switch 12a is closed, the lighting of the indicator light moves from the upper side to the lower side in FIG. The data is updated to indicate the size indicated by the light. However, this operation is performed only when the size data has not been received from the copying machine 800; if the size data has already been received, the process proceeds to step 11-12-0 and updates and displays the data in response to the key-in. No update, key switch 12
c = 12 Even for key-in by h, cpU
14 performs a similar operation.

The reason why the input data from the copying machine 800 is given priority over the settings made by the operation board 12 is that the input data from the copying machine 800 is prioritized.
This is because data starting from 00 is more reliable. When no data is received from the copier (for example, when the copier is not connected).

Alternatively, when only part of the required data is received, the missing data is updated and set in accordance with the key input from the operation board 12. When no data is given from the copying machine and there is no key input on the operation board 12,
The setting data is the standard data mentioned above. Although it is different from the step development of the illustrated flowchart, a start signal for the mechanism of the sheet processing machine to start operation is also received from the copying machine 800, and is also keyed in with the start key switch 12i of the operation board 12. However, when even some data is being received from the copier 800 (OB
For the copying machine input bit R=1), the key-in of the start signal by closing the switch 12i is not accepted in step 38. In this way, even when starting the processing mechanism, priority is given to the start signal from the copying machine.

The operation board 12 and its key-in read/data set are used when no copying machine is connected, and.

This is meaningful when the sheet processing machine 900 is connected to a copying machine that does not transmit all the required data, and when no external device (host) is connected to the sheet processing machine 900, or when the host's insufficient functions are compensated for by key-in. cormorant.

Now, if you set the data in step 8 (set the data received from the copying machine), or if you set the data in step 13 (set the key-in data), or the copying machine does not send data (5)L If there is no key-in (9), the process advances to step 14 in FIG. ).

If the vertical fold &90' turn control unit 20 is ready in step 14 of FIG. 7b, the unit 3 is ready in step 16.
Checking whether 0 is ready or not If the 0 feather digit control unit 30 is ready, it is checked in step 18 whether the unit 40 is ready.

If the punch control unit 40 is ready, step 2
0, it is checked whether the unit 50 is ready. If the stamper control unit 50 is ready, it is checked in step 22 whether the unit 60 is ready. When the vertical conveyance & discharge control unit 60 is ready, all units are ready and can execute sheet processing, so set l indicating processing possible in the ready standby bit of the operation board register OBR (24). Compare the data in the operation board register OBR and the data in the previous operation board register POBR (25). Note that the previous operation board register ○BR was cleared in the initialization in step 1, so when proceeding to step 25 for the first time, 1 The contents of the two do not match. This applies to each unit 20 to 60 in steps 27 and below, which will be described later.
This means that the processing mode data transfer is not executed.

Therefore, first in step 26, the operation board register OBR is
The data is updated and stored in the pre-operation board register POBR, and the process proceeds to setting the A version processing mode to the unit 20 (27) in FIG. 7c.

Setting the A version processing mode to the unit 20 in FIG. 7c (
In step 27), first, the size is determined from the data of the size designation bit of the operation board register OBH (271).

If the size is A2, next is the OBR digit selection pill.
(272-276), and if there is no fold, transmits data indicating A2/longitudinal/passing mode to the unit 20 (273). When it's folded in four.

Data indicating the A2/vertical folding mode is transmitted to the unit 20 (275). When folding in half, unit 20 has A
2. Send data indicating vertical/passing mode (277)
. If it is a JIS fold, data indicating A2/edge fold/JIS vertical fold mode is sent to the unit 20 (278
).

If the size is not A2, the process advances to step 279 to see if it is A3.

If the size is A3, refer to the vertical/horizontal designation bit of the OBR, and if it indicates vertical (280), transmit A3/vertical/passing mode to the unit 20 (281);
If it indicates the side, refer to the digit selection bit of OBR (282), and if it is unfolded, unit 20
The A3/horizontal/passing mode is transmitted to (283). If something happens, the unit 20 will have an A3/90''
Send turn mode.

When the size is A4 (285), refer to the vertical/horizontal specification bit (286), and if it indicates horizontal (286), transmit A4/horizontal/passing mode to the unit 20 (287). ). If it does not indicate the side, send A4/90@turn mode to unit 288 (2
88).

When the size is the B version, in step 28, a mode corresponding to the size etc. is transmitted to the unit 20 in the same manner as in step 27 described above. Step 27 A2 to B3, A3 to B
4, and if A4 is read as 85, it becomes the content of step 28.

With the above, when unit 20 is ready, unit 10
A control operation mode instruction is given to the unit 20 from the control unit 20, and is set in the microprocessor of the unit 20.

The CPU 14 of the unit 10 then proceeds to setting the blade folding mode (29) in FIG. 7d. In this step 29, first, the digit selection bits of the operation board register OBR are referred to (291, 292, 294), and when there is no fold, the pass is sent to the unit 30 with size data attached (295). In the case of 4-fold, 2-fold, and JIS fold, the size specification bit of the operation board register OBR “
The data and digit selection bit data are transmitted to unit 30 (293, 296). That's all for units 10 to 30.
A control operation mode instruction is given to the unit 30 and set in the microprocessor of the unit 30.

After completing the blade folding mode setting (29), the CPU 14 of the unit 10 sets the punching mode (30).

In this case, the operating board register OBR.

Referring to the size specification bit data, digit selection bit data, and punch selection bit data (301 to 30
6, 308, 309), and when the final size is A4 and has a punch, the A4/punch mode is sent to the unit 40 (307).

When the final size is B5 and there is a punch, the B5/punch mode is sent to the unit 40 (310), and in other cases, the non-punch mode is sent to the unit 40.

After completing the punch mode setting (30), the CPU 14 of the unit 10 sets the stamp mode (31).

In this case, the stamp selection bit of the operation board register ○BR is referred to (312), and if it is 1 indicating a stamp, the stamp selection bit, stamp position bit, and issuer selection bit of OBR are sent to the unit 50. and send the drawing type selection bit data (313)
. A stamp selection bit of 0 sends a non-stamp signal to unit 50.

After completing the stamp mode setting (31), Units) -1
The CPU 14 of No. 0 sets the paper ejection mode (32).

In this case, refer to the paper ejection selection bit in the operation board register OBR (321); if it is 1, it instructs the unit 60 to eject the paper to the sorter (323); if it is O, it instructs the unit 60 to eject the paper to the tray (323); 322).

i When the paper ejection mode setting (32) is completed, the control operation mode has been instructed to all units 20 to 60, and the CPUs of these units each hold the received instructions (mode data).

The CPU 14 of the unit 10 then returns to step 24 in FIG. 7b, and proceeds through step 24 to step 25.

Here, the data of the previous operation board register POBR is changed to the operation board register O by the execution of the previous step 26.
Since it matches the BR data, steps 25 to 3
Proceed to step 3.

In step 33, all the indicator lights on the abnormality display panel 33 are turned off, the standby indicator lamp on the operation board 12 is turned off, and the ready indicator lamp is turned on. Next, a ready signal is output and set to the copying machine 800 (34), and the process returns to step 5 in FIG.
Wait for key-in.

When a start signal arrives from the copying machine 800 (6), refer to the ready/standby bit of the operation board register OBR (35), and if it is 1, normal operation is possible, so the units 20 to 60 are given a predetermined tie. The start signal is sequentially transmitted during the timing (37).

Then proceed to read the status of the step below again, unit 2
Each of 0 to 60 starts driving the conveying roller when receiving a start signal, and when the 0 paper arrives at each sensor, a predetermined control operation is started.

Before or after the control unit 10 gives the start signal to the units 20 to 60, the unit 20 waits (
When the unit 10 (?: PU 14 reads this in step 14 of FIG. 7b and proceeds to abnormality processing (15) of the unit 20), the unit 10 (?) reads this in step 14 of FIG. 7b and proceeds to abnormality processing (15) of the unit 20. The copy machine input bit of the board register OBH is referred to (151). If it is 1, data has been received from the copy machine 800 and sheet processing has not yet started or has already started, so the copy machine 80
0 (152). and O.B.R.
Set the ready/standby bit to 0 indicating that it is not operable,
The ready indicator light on the operation board 12 is turned off and the standby indicator light is turned on (153). Next, abnormal data is received from the unit 154 (154), and if the abnormal data indicates a paper jam, an indicator light on the abnormal display panel 13 corresponding to the position data is turned on (156). If the abnormality data indicates that the paper is not jammed, all the indicator lights associated with the abnormality mechanism unit on the first display panel 13 are turned on (157), and the process returns to the state reading from step 5 in FIG. 7a.

Before or after the control unit IO gives the start signal to the units 20 to 60, the unit 30 waits (
If the CPU 14 of the unit 10 reads this in step 16 of FIG. 7b and proceeds to the abnormality processing (17) of the unit 30, this abnormality processing (17) is the same as the above-mentioned abnormality processing. This is the same as (15).

The operation of the vertical folding mechanism unit 100 brought about by the vertical folding &90'' turn control unit 20 has been explained in the mechanism description thereof. Therefore, the explanation of the control operation of this unit 20 is omitted here because it is redundant.

Next, the advantages of the embodiments described above will be summarized and explained.
