41J are arranged in parallel below the non-sort tray 17 as shown in FIGS. Efficiency can be improved. For example, in the guide section 43, first, as shown in FIGS. 3 and 4, a cylindrical or U-shaped frame 44 is attached to the linear vision block 42B, and then the frame 44 is moved horizontally. In order to prevent this, a guide roller 45 is attached to the left end of the frame body 44 as shown in the third figure, and a sipe guide 46 equipped with a long hole 46k that fits into the guide roller 45 is attached to the pace plate 4. installed on.

(hereinafter also simply referred to as a caliper motor) 54, a timing belt 55 stretched between the DH self-idle gear 5JA and the drive gear 51B, and a connecting member 56 that connects the timing belt 55 and the frame 44. By driving the gear ridge motor 54 a predetermined number of steps, the carrier 50 is moved to a desired bin position. Note that the guide portion 43 is connected to a bin 41 fixedly arranged on the frame cover 6.
Although the structure was constructed by moving the carriage 5o with respect to the bins 41 and 41J, the main point is that the guide members 47A and 47B are moved relative to the bins 41 and 41J. It is only necessary to guide the paper that has been fed under the arm to a desired bin, and it is also possible to configure the bin to be moved.

Paper ejection switch (hereinafter also simply referred to as CUP paper ejection switch) 61 to the CiζG paper ejection switch 60'f: These are used for detecting paper jam ip before passing, detecting the driving timing of the carriage 50, etc. (Details will be described later.In addition, an initial switch 62 that comes into contact with the front guide 47k of the front 81J2 carriage 50 is provided at the upper end of the linear guide rail 42A, and the initial position of the carriage 50 is A door switch 63 is attached to the double frame 5 as shown in Fig. 2. Opening/closing of the frame cover 6 is detected.

The power source for the sorter 1 is taken out from the main body of the copying machine 20, and the power is turned off, for example, by inserting a glove into a cover (not shown) provided on the main body of the copying machine 20.

Next, the configuration of the control section of the sorter of the present invention will be explained with reference to FIG. In the figure, a portion 70 surrounded by a chain line is I
The IJ control section and other sections represent mechanical sections or external devices. The mechanical parts related to the sorter shown in the figure are a transport motor 25, a caliper motor 54, a guide selector solenoid 13C, a suction 7 ann 22, and a CRG.
(Carriage) Paper ejection switch 60. The initial switch 62 and the door switch 63 are used to set the external device c + R. 7ζ. Also, an operation panel group 90 is provided on the main body of the photographing device 2.

Here, a specific example of operation 1/[pair 90] is shown in FIG. That is, 9) is the two-tabi/display section, and 92 is the copy'

The two-tabi/display section 91 includes ten bin display runs f (for example, light emitting diodes 291 to 91J and non-note thorn display unno (for example, light emitting diodes) corresponding to the bins 41A to 41J of the MiJ storage section 40 ) 91N.The warning display section 93 is
When an abnormality such as a paper jam occurs, a corresponding warning will be displayed.

The sort button 97 sets the sorter mode with one press,
This is to set the non-sort mode with another suppression. The interrupt button 98 is used to set the interrupt mode by pressing it once, and cancel the interrupt mode by pressing it 91 degrees.

Note that the conveyance motor 25 and the caliper motor 54 are stepping motors of an excitation phase switching drive type.

Before explaining the control section 70, an example of the use of the stepping motor in the present invention will be explained.

As is known, the rotation of a stepping motor can be precisely controlled by controlling the number of excitation pulses supplied to the PC. Therefore, if such a stepping motor is used for one time to move the carrying tip 5o, the movement amount of the carrying tip 5θ can be controlled by the excitation number τ current, so positioning of each bin of the sorter is extremely easy. . Furthermore, since the stepping motor can control the rotational speed by changing the entire frequency of the excitation jd pulse, when moving an object, it moves at a low rate at first, and then it starts to collect bacteria in the middle. If you move at high speed, if you decelerate and stop at a low speed without a board, you can control the speed by dividing it into three attack stages.9, this JL
1) Positioning can be performed smoothly. P4
In the iJ example, both the transport motor 25 and the carriage motor 54 are driven by controlling the continuous wave 1i1, but the two ministries have different usage requirements and specific control instructions. I also have a slightly different mindset. That is, for example, the speed control of the transport motor 25 is performed during a constant speed period T as shown in FIG.
Two cases are assumed to be 417, and the slopes are set to be equivalent to one acceleration period T1 and one deceleration period T3. On the other hand, the carriage motor 54 receives a force in the counter-rotational direction when the carriage moves upward due to the weight of the carriage 500, and a force in the rotational direction when the carriage moves downward, as shown in FIG. 9(b). , (e
), the speed control characteristics are changed depending on the direction of movement. In other words, Figure (b) shows the case where the carriage horn is moving upwards, and the initial speed is reduced to accelerate over time, and when the carriage is stopped, the Since the amount of vehicle acts as a brake, the deceleration time should be shortened, as shown in the figure (e).
&yo When the carriage moves downward, when accelerating, the amount A of the carriage can be used as power, so the initial speed is increased, and 111 hours are used (dagger) (However, when stopping, the inertia due to the foot of m acts) It takes time to decelerate and keeps the final speed small.Such control I11 is controlled by C, which will be described later.
I'U 73 and the timer count control 7) eC based on this command are now activated.

Historically, stepping motors have the characteristic that if the frequency of the excitation pulse exceeds the self-starting frequency, they will step out and stop without causing any stress, and when they return to the self-starting frequency, they will continue to rotate. , for example, the upper y of the movement area of cap zo 50 as explained in the example.
By providing an initial switch 62 at the position 1d, the initial switch 62 acts as a stopper to cause the stepping motor to stop automatically. As a result, the initial switch 6
From the time point 2 is activated, the carriage motor 54 is continuously rotated until the carriage 500 is in the position of the uppermost bin 41, so that the initial position can be settled. In addition, regarding the first reaction t0 of this initial position, there is also the fact that when the stepping motor is not energized, V (holding force, force torque) is small. 6. By touching the stopper (for example, the stopper no. 9' shown with a steel wire next to the door switch 63 in Fig. 2) provided at the bottom of the lower box and stopping δ, the initial IXL is set. -C may also be used for direct identification.

In the above embodiment, when using the sorter, 4! ＠The moving caliper 50 is moved upward once and the initial switch 62 is set to move 1.'.However, if a problem such as a paper jam occurs during movement, the stepping motor is turned off at 70. There may be a problem that the step-out may occur, and even if the interference remover 9 is removed, it will not move any further.For this reason, the steppinograph V drive frequency may be changed between fast and slow speeds as shown in Fig. 10. Change 6 as if repeating,
Even if a step-out occurs at time tl indicated by the broken line during movement, the next self-start! Cherry blossoms at time t2 of the father point with lII frequency fO! lI

and the ink face portion 78.

The counter counter unit 72 is used as a timer counter 7.2A for controlling the transport motor and a timer counter 72B for controlling the caliper motor, and is used as a normal timer to determine the timing of each unit and to prevent paper jams. JAM) and a timer counter 72C for detection. +4iJ driver section 77 is
Conveyance morph driver 77A, caliper motor driver 77B, guide selector, suction sorter driver 77
It is 48 ta by C. The front interface section 78 is composed of an output ink face 78A, an input interface 78B, and a sensor interface 78C. All parts 74 are equipped with a stepping motor 25.5 as described above.
4'f: Data for production control, timing data for detecting all jams, t1 time node, and CP
Contains ROtA, which stores the P2S5 processing procedure, and includes 1ζAM, which allows you to sort the current living position tray data in correspondence with the amount of carriage movement. .

Here, an example of the data stored in the storage section 74 will be specifically explained. First, as the data for driving the stepping motor, time data indicating the amount of movement of the carriage corresponding to the interval between bins of the sorter is stored. In this case, it goes without saying that the speed control data shown in FIGS. 9 and 10 is stored. Additionally, 4-bit data indicating the bin position is stored in this storage section, and the initial switch 62 is operated to move the carriage 5.
Data indicating the current bin position can be sequentially selected in accordance with the amount of movement of the stepping motor after the initial position of 0 is set. Further, this storage section stores reference data for jam detection. That is, the time data for the paper passing through the COP paper switch 61 of the copying machine main body 2 to reach the CRG paper discharge iron 0 attached to the cartridge ridge 50 on the sorter 1 side is stored in the memory. In particular, in the above-mentioned embodiment, since the above-mentioned time differs by C depending on the position of the carrying horn 50, the time data of the number of g is recorded according to the change in the amount of movement of the carrying horn moving to the previous valley bin. ．． It has been done. The reading start timing of this time data corresponds to the timing at which the sheet is ejected (No. N EXIT occurs).

Next, the contents of the 1st number processed between the control section 70 and each mechanical section will be explained. A signal S1 from the conveyance motor driver 77A causes the feed motor 25 to rotate clockwise during sorting to drive the electric transmission belt 21, and drives the non-note roller 16 to rotate counterclockwise during non-sorting. This is the 1d model. 1g S2, which is about to be sent out by the caliper motor driver 77B, is) 11
Move the lever by rotating the lever motor 54 in the desired forward or reverse direction as described in J.7.
I'm going to buy Kome no 1d. One of the signals from the guide selector and suction fan driver 77C
By turning off the guide selector solenoid 13Cf, the υ guide selector J3 (!- is switched to the non-sorting side, and No. 16 is used to switch to the sorting side in the excited state, and the other No. 1d for driving the suction fan 22. Among the signals 85 to S7 manually inputted to the sensor interface 78C, the 1st signal S5 from the CtG paper discharge switch 60 indicates that the paper is on the carriage 50 as described above. 1 sent out when passing through the bottle roller part of
No. 6 is always used for jam detection. The isa signal S6 from the initial switch 62 is sent out when the carrying horn 50 reaches the initial switch, and is used for setting the initial position of the carrying horn.

The first gear S7 from the door switch 63 is Tsutaka-to-6.
When it is open or open, it is a signal for stopping all motors, disabling the use of the sort button 97 and copy button 99, and also canceling (resetting) the jam signal S-JAM generated in the sorter section.

Next, the contents of various signals transmitted and received between the control section 70 and the copying machine main body 2 will be explained. Output interface 7
From &A, Sorta Ready 8-RDY, Sorta On 5
-ON, Nutabi/Position 5-BIN, Sotanoyam 5-
The signals JAfvI and JAfvI are output and processed by the copying machine main body 2. Sorter Ready 841) Y lights up the corresponding lamp on the panel of the copier main body 2 when the carrying tip 50 is moving to the initial position, during note/non-sort switching operation, when sorter clear excitation 4/[ is in progress, and when the sorter cover is open. It can be turned on at other times and can be used as a sorter! Enter the number 1, which indicates 114.

Sorter ON 5-ON is required by a 7° signal that indicates whether or not the sorter 1 is attached to the copying machine main body 2, depending on the connection state of the power connector.

The sorter bin position 5-BIN indicates the position of the bin that corresponds to the handle 5θ. The bin display rung of No. 91 has started to emit light. With this tool, it is possible to easily recognize, for example, the position of the bin where the paper is stored or the position of the bin (1) where the paper is stored. Sortanoyam 8-JAM is a number 1 output that is output when a jam occurs in the sorter. In particular, in the present invention, it is output not only for the number of pages in the sorter J but also when the number of copies to be sorted exceeds the number of bins. In Europe, it is designated as No. 1B, which indicates "unsuitable for separate storage."

From the copying machine main body 2 to the manual interface 711B, sort 5ORT, paper ejection gXIT, copy end CPYEND are sent.
, sorter clear 5-CLR signals are manually input. 5ORT is a signal instructing the sorting state of the sorter 10, and upon receiving this 1h signal, the sorter starts operating. Paper ejection ffXIT is CUP J)p in the subject body 2.
No. 16 outputted from the paper switcher 61 turns on the edges of the paper from the leading edge to the trailing edge, and is used as a high-speed signal to eliminate the noise detection as described above. Copy end JC
PYENi) is a signal that is output when copying the final paper.
After storing the paper at this time in the bin, the sorting operation ends. The output of the sorter clear 5-CLR is turned on when the power is turned on, and upon receiving this signal, both parts 70 of the carriage 50t are moved upward until the initial switch 62 of the carriage 50t is activated.

Next, the entire operation of the apparatus of the above embodiment will be explained.

First, before explaining the overall operation, a method of controlling one drive of the Mt stepping motor will be explained with reference to chart 70 in FIG. As shown in the figure, the CPU
At ys, a judgment is made as to whether or not to start driving the motor, and if it is to start driving, the interrupt reception mode is entered.6.1.
Outputs the 7 multi-power rotation designation data =V in the section 74 to designate the excitation phase switching order via the output port door 5 and the caliper motor driver 77Bf, and the time required for the movement of the sorter 1 between the valley bins. All data listed above: 1, part 74
ry v is brought out from the ROM of the timer counter 7.
Set it to 2B. The timer counter 72B performs subtraction counting based on the clock signal sent from the timer counter controller function, and notifies the CPU 73 when the current value reaches "zero" (timeout). CPU 7 that received a time act? In this case, an excitation phase switching command is output to the carriage driver 77B, which causes the carriage motor to rotate one step.

Extract the data φt from the shout ROM and repeat the above operation so that the desired step rotation is performed.The S# control of the speed characteristic at this time is as described above when the 5CP lower 3 is set to the RO
This is done by outputting control data tr=9 from M and giving a command τ to the timer counter controller 71.
Control is performed in accordance with the speed characteristics as shown in FIGS. 9 and 10 of the iJ journal. Here, the setting of the initial position of the caliper horn 50 as described above is performed as follows. When the sorter clear signal is output after loading the surface line,
The CPU 73 continuously takes in 140M data in the storage section 74 and drives the caliper motor 54 in steps. Such step drive is carried out and the caliper 50

is set at the top bin 41. This position of the carriage 5o becomes an initial position.

When the initial position of the key 5o is set in this way, each timer force 7. ? As A to 72C become clear, on the 6th, among the 4-bit data shown in bins w and f stored in section 74, the data shown in success bin 41, shown as 7z, is selected. Based on this data, the bin display lamp 91k of the sorter bin opening section 9 in the operation knob section of the copying machine main body 2 is turned on. Thereafter, the timer counter 72 is set as the carriage 50 moves.
While the cutting of tJJr constant is carried out at B, the count out of this counter is followed by 7ζ (therefore, ~91J is displayed on the bottle display lamp 91), and the bottle is displayed. It depends on knowing the location.

Next is the 12th time chart and! A413 diagram (7)
The overall operation of N-RI will now be explained with reference to 7a--y-yards.

Non-sort operation 2 When the m source is turned on, it is judged whether the sorter 1 is desecrated or not by the presence or absence of the connection of the connector described in NiJ, and if the iron layer 16@5-oN is output, then the sorter It is determined whether the data is sorted or not by the presence or absence of the signal 5ORT from the note button 97 on the copying machine main body 2 side. At the same time, it is determined whether a sorter clear signal 5-CLR is output from the main body of the copying machine. If both conditions are met or not, the flow shifts to a non-sort operation. That is, since the sorter clear signal 5-CLR is not generated, the outputs of the guide selector, suction fan driver 77c'iJ, etc. are not activated, the guide selector solenoid 13C is not energized, and therefore the guide selector 13 is not activated on the tray 17 side. It remains set to the state in which the paper is transported to γ. Then, it is determined whether or not a copy end signal cPYEN1) is output from the copying machine main body 2, and if it is not output, the bacteria that pressed the copy button 99 of the operation panel section 90 and the copied paper are COP. When the paper reaches the paper ejection switch 61 and operates, the EXIT signal is sent, and after a certain period of time (while the paper moves between the paper ejection rollers of the copying machine body and the sorter paper ejection row 2), the transport motor is activated. 25 is rotated counterclockwise, and the non-sorting drawer 216 rotates to guide the paper to the tray 17. Non-sort roller 1 at this time
The rotational speed of 6 is set to be equal to or significantly faster than the sheet discharge speed of the main body of the copying machine, so that the sheet of paper t is smoothly conveyed. When the paper ejection erasure signal EXIT is cut off, the rotation of the backward conveyance motor 25 stops for a certain period of time, but when the next paper ejection number 1-EXIT occurs during the warping, the rotation continues again. As a result, the non-sort operation is performed, and when the crossroad copy signal cpygNo is outputted from the copying machine main body 2, the operation ends after the last sheet is stored in the tray 17.

Sorting operation 2 When the sorter 1 is in the iron layer state and the sort button 97 is pressed and sorter clear No. 18 5-CLR is generated, the control section in the sorter 1 receives this and sets the initial position of the carriage 5θ as described above. I can do it.

That is, the carriage 50 moves upward and stops when the initial switch 62 is turned on, and then the carriage motor 54 rotates in the reverse direction several steps, and the carriage 50 moves upward.
? ! - Position the topmost bin 4JA. At the same time as this, the guide selector solenoid is energized and the guide selector 13 is switched to the conveyor belt 21A, 27B side.

At the same time as the guide selector is switched, the suction fan 22 also starts its full operation. Note that if the copy key is pressed immediately after the sorter button 97 is pressed, the positioning operation of the carriage is performed while the paper is being conveyed within the copying machine body, so there is no waiting time problem. It is /j, that occurs.

Next, the CPU 73 in the control unit 70 determines whether the door switch 63, which indicates the open/closed state of the sorter cover 6, is in the operating state or not, and also determines whether the door switch 63 is in the operating state or not depending on the operating state of the timer counter 72B. J, -) 50 is in the home position,
If there is no problem, sorter ready QK No. 5-RDY occurs, and this (therefore, copy operation and sort operation Ff=J'
The state of ability is confirmed.

After that, copy from the original copy body 2 - End No. 16 CPYEJJ
D is generated and it is judged whether or not lζ is δ, and if 7d is generated, the copy paper g that was partially copied passes through the copy ejection switch 6) in the copying machine 4j and the Q main body 2, and then 1 at this time. No. 1 paper signal EXIT is manually input to the sorter 10 control section 70. The control unit 70 of the sorter 1 (rJ
, I) After one set time has elapsed, the conveyance motor 25 is driven to move the conveyor belt 21 to the conveyor belt 21, and the bin roller 48 provided on the roller ridge 50 is rotated via the bin roller motor 49C. . In this case, the bin roller 4s is driven so that the zero movement of the 8M belt is also faster.

The paper sent from the copying machine main body 2 is attracted to the conveyor belt 21, 2iB, and conveyed downward. Then, set Yayarino 5 in the top bin 41A position.
When the paper reaches the paper guide section 0, it is pulled from the conveyor belt and guided to the -C bin row 248, and further stored in the uppermost bin 41A by the bin roller 48. Since the bin roller moves faster than the transport belt, storage is carried out smoothly. Here, press the carriage ejection switch (
By determining the operating state of the CRG paper discharge switch 60, it is possible to know whether a paper jam 9 (jam) has occurred. That is, the time required for moving the paper stored in the ROM is compared with the time from when the actual EXIT signal is generated until the CRG paper ejection switch is turned on. If it does not operate, the warning display unit 93 displays the sorter cover S-JAM, determines that sorting storage is inappropriate, shifts to the non-sort operation as described above, and stores the sheets in the tray 17 without stopping the operation. I'll do what I do. At this time, it is the sorter cover (frame cover) 6 that releases the jam state.
The opening is done by -. Frame cover 6
When opened, all motors will stop. ps due to the operation of the door switcher 63 that comes into contact with the frame cover 6.
- The JAM signal is released. If the problem is resolved, cover 6 should be closed.
Move to the bottle position immediately before opening. This genius is sir
The CPU 7J in the CPU 70 remembers the bin position and issues a command to move from the initial position to the current position. In addition, cover 6
While the copy wholesaler 99 is open, the copy wholesaler 99 is in an invalid state. Note that the time from when oxrr No. 4.1 is output until the paper reaches the bin varies depending on the position of the bin, but the CPU determines the location of the bin where there is a waste. Therefore, VL is always judged against the corresponding base time t. Next, it can be determined whether the carriage 50 is at the upper or lower limit of the movable tag wall. This judgment is made by the CPU 73, which remembers the current position of the carriage 50, depending on whether or not there is a 1ζth bin in which the carriage moves further 7 times in the 4th direction. Then, when the position of the position is neither the upper limit nor the lower limit, the process returns to the flow of determining whether or not the copy end No. 1d CPYEND has occurred. Such an operation is repeated to perform a sorting operation according to the set number of copies. Then, for the next document, the carry 50 is sequentially moved upward from the position of the bin containing the final number of copies last time, and a sorting operation is performed. - Rather, when the copy end No. 1g CP gallery ND is output, the last sheet is stored in the bin and then the operation is started.
Complete. At this point, we are going to make a decision when the number of copies set for sorting exceeds the number of bins.

If V/1j, then in this sorter 1, the number of bins is V, which is 1O1lI!
11, but the number of notes set is 12, which is 1, -
Assuming a meeting, up to 10 copies are stored in bin 41 in Figures 1-10.
It will be stored separately from A to 41J, but for the number 6fj15 exceeding t, -C is the target. Therefore, the CPU 73 determines that the subsequent sorting and storage is inappropriate and causes the remaining 02 copies to be stored in the tray 17 by moving to the flow of the sorting operation.

In addition, in the above operation, *a bevel 21A.

21B will stop if a new EXIT code is not signaled even after a certain period of time has elapsed. In addition, when specifying a sorter, the carry-tip motor 54 is energized and the carry-tip 50 is fixed at the current position, but at this time, even when the excitation current is fully rotated, it is either delayed or intermittently energized. In particular, it is desirable to suppress power consumption and heat generation. Furthermore, the suction fan 22 applies exhaust air to the carriage motor to cool the motor.

Next, we will discuss interrupt mode. First, in multi-copying before interruption 9, all copied sheets are stored in the tray 17 when the sorter 1 is not in use. At this time, the non-sort display rung 91N lights up in the sorter bin display section 9. When the shoe 09 button 98 is expanded 6, the interrupt mode is set.

In this state, in the non-sort mode, the copy paper that has not yet been inserted is stored in the tray 17, the paper that has not been inserted is stored in the bin 41k, and the sorter bin display is displayed. At 91, the bottle light indicator lamp 91k emits light. When using sorter 1 for interrupt copy,
The iuD-containing copy sheets are sorted and stored in the valley bin. For example, if you sort 3 citrons, bin 41
41B, 41Ci+copy paper is sorted, sorter bin display section 91 U) bin display rung 91 person, 9
1B and 91C emit light.

11 Sorter lJl in multi-copy before D inclusion:
If you do not use it, it will be copied to +1"1".
c The papers are sorted and placed in the valley bin VC storage δ9.For example, 5 unique sorting was performed, so the papers are sorted into bin 41, 41B, 41C, 410°41H, and the bin table/ Liao Unzo 91A.

91B, 9IC, 910, and 91E emit light.

7) In this state, when the interrupt button 98 is pressed and the interrupt mode is set W-a, and the non-sort mode is set, the paper for the interrupt copy will be interrupted. It is stored in a tray 17 that is not used for copying before printing. In this case, the non-sort display lamp 91N emits light. When reusing sorter 1 by interrupt copy,
Copy paper is stored in a bin other than the ζ bin that has been used one more time before the 9th interruption. For example, before interrupting bin 41
When paper sheets 41B, 41C, 41D, and 41E are stored in paper sheets, when attempting to make an interrupt copy of 3Jffl, the paper is stored in, for example, bins 41F, 41G, and 41H, and the paper is stored in bins 41F, 41G, and 41H. )7f91F, 91G, 91H
are other display lamps 91A, 9113, 91C291D
, 91E. In this case, the bottle light indicator lamp 9 should be placed on the 7
1 F + 91 G + 911 (grapes can be extinguished. By the way, when the number of sorts before the interrupt and the number of sorts at the time of 9th insertion are equal to 61), the utilization 9 included ÷ c corresponding to the amount of insufficient sorting of copies] Paper is stored in the tray 17 as a non-sorted sheet at once.

In this case, all the sheets for interruption copying may be stored in the tray 17 at once from the beginning. in this way,
By storing the paper for interrupt copying separately from the paper before interrupt copying, and by displaying all the storage locations of Schiff J), the paper for interrupt copying can be stored independently without being mixed with other papers. It can be taken out.
