Description

[Detailed description of the invention]

The present invention relates to an automatic document handling device in an image forming apparatus such as a copying machine that forms an image using a document. In particular, the original is automatically conveyed to the original exposure unit of a copying machine, etc., optical scanning necessary for image formation in the copying machine, etc. is performed, and the original is automatically returned from the copying machine etc. This is related to the equipment that was used for this purpose. In conventional automatic document handling devices such as copying machines, the next person cannot use the automatic document handling device until the copying process of the first person's document is completed. If a document is placed in an automatic document handling device during the copying process of the previous person, it is often extremely inconvenient that only the number of copies set by the previous person can be made. Also, if you wait for the first copying process to finish, in order to actually make copies sequentially, you will have to line up,
The reality is that you have to line up. However, it is clear that these methods are extremely inefficient and time-consuming. The present invention provides a useful document handling device that eliminates these disadvantages. That is, an object of the present invention is to provide an automatic document handling apparatus that is capable of setting processing conditions for a plurality of documents, and that can set processing conditions for other documents while processing one document. To describe the present invention in more detail, a plurality of placing means for placing originals to be processed are provided, and the originals are conveyed by the placing means. Specifically, the document is sent to a document exposure unit for image formation processing in a copying machine, for example, and after the image necessary for copying is formed there by exposure means such as optical scanning, the document is returned to the document tray. It will be done. At this time, the first person places the document on a loading device that has multiple loading devices, and instructs the necessary processing conditions using a copy number setting device, etc., and the document can be processed, and the document transport processing operation begins. be done. During this document transport process, a person who wishes to process the second and subsequent documents also places each document on a separate loading means and similarly sets the number of copies using the corresponding copy number setting device, etc. By setting the processing conditions, as soon as the first person's document conveyance process operation is finished, the second person's document conveyance process operation can be started immediately and automatically. Here, processing conditions include, for example, not only the number of copies per document, but also copy density, copy magnification, etc., which are stored for the document.
This means that the processing conditions for a document can be changed each time the document changes, and the processing conditions can be changed so that document processing operations are performed one after another under the set processing conditions. That is, the present invention provides input means for inputting processing conditions for each of a plurality of originals (keys 0 to 9 in FIG.
I/O-4, etc.), a storage means (RAM in FIG. 4) having a plurality of storage areas and for storing the processing conditions of the original inputted by the input means, and a plurality of storage areas on which the original is placed.

This is an automatic document handling device characterized by the following. Further, the present invention will be described in conjunction with the embodiments. As will be described later, for example, when a document placed in the document placement bin 6 is being transported, another document is set in another document placement bin 9. The CPU shown in Figure 4 is
This is detected by ORG (which is a control means shown in FIG. 16 and explained in detail in Step 3 of FIG. 11), which is a control procedure for document detection in Steps 8 and 9 of FIG. 13. Then, KEY IN (the control procedure shown in FIGS. 18 and 19, and explained in detail in Step 4 in FIG. 11), which is a control means for key input control, is used to control the other document loading bin 9. Enter the processing conditions for another document set to
Store in RAM. Then, the conveyance process of the original placed on the original placing bin 6 is completed, and the process shown in FIG.
In step 15, it is determined whether a document is placed in another document placement bin, and the process returns to step 6 in FIG. 12 to carry out another document conveyance process. According to the present invention, it is possible to make a reservation for document processing under desired processing conditions even while another person's document is being processed.

Next, the document transport section 3 is configured to place a document from a copying machine or the like 37 on a document glass 38 on which optical scanning or the like is performed. Further, document receiving bins 60, 61, 62, 63, and 64 are installed corresponding to the document placing bins 5, 6, 7, and 8. That is, the original 10 placed on the original placing bin 9 is returned to the original receiving bin 60 when the desired purpose is achieved in the original conveying section 3. That is, the document 10 that has passed between the guide plate 67, the roller 68, the guide 69, and the conveyor belt 59 is rotated as shown in the figure by the operation of the plunger with the guide lever 65 around the lever shaft 66 as a fulcrum, and the document 10 is transferred to the document receiving bin 60.

The roller 3 is attached to the shaft 100 of the pulley 39 so as to engage with the roller 3.
A conveyor belt 41 made of rubber is hung around 9 and 40. A partition plate 42 is attached to the inside of the conveyor belt 41, and by the action of a suction fan 43, the inside of the partition plate becomes a suction box. Further, a partition plate 44 is similarly attached to the lower part thereof, and the interior of the partition plate becomes a suction box due to the action of a suction fan 45. The original that has left the original placing section 2 is placed on the guide plates 46 and 47.

The document passes between the rollers 50, the guide plate 51, and the guide plate 51, and reaches the document glass 38, and the paper leading edge detection device 52 stops the movement of the conveyor belt 41 by releasing an electromagnetic clutch (not shown). ,
When the image creation process is completed to obtain a desired copy by detection by the scanning completion detection device 53 of the image creation process such as optical scanning of a copying machine, the original is moved to exit guides 54 and 55 so that it can be replaced with the next original again. The document exits from the document conveyor 3 after passing through. A roller 56 inside the conveyor belt 41 is provided so that the document can be smoothly ejected. Note that providing a large number of suction holes in the conveyance belt 41 in the document conveyance unit 3 provides an extremely good conveyance force when the document reaches the lower part, that is, the document glass 38, but the document is small compared to the copy paper. In some cases, there is a disadvantage that the shape of the hole is clearly reproduced. Taking this point into consideration, it is necessary to plan for effective conveyance with the minimum number of holes. In the document receiving section 4, a conveyor belt 59 is hung around rollers 57 and 58. A gear 101 is fixedly provided to drive the original conveyance section 3.

Activation of solenoid 110 causes solenoid lever 108 to move as shown. A control device for performing these operations is shown below, and although this circuit may be provided in the copying machine or in the copy requesting device 1, the following explanation will be based on the control device in the copy requesting device 1. Let's explain the case where you have a device. FIG. 4 is a block diagram of the control device. In the figure, the ROM is a read-only memory that stores the sequence contents of the automatic document handling device in a pre-ordered order at each address, and can retrieve the contents each time an address is set. Details will be shown. In other words, the control contents are set in advance in a well-known matrix circuit using an 8-bit binary code in order from address 0 to the required final address (including not only the operational output of the device but also the control contents of other circuits).
Remember. RAM is a read/write memory that stores the number of copies and temporary control signals during process control, and a memory that stores a set of binary codes. One set is composed of a plurality of sets, and an arbitrary set is selected by an address designation signal, and data is written to or read from a plurality of flip-flops within the set. In addition, in FIG. 6B, the memory address is expressed in the form of, for example, "XO31", where the lower one digit represents the column, the upper two digits represent the row, and "XO31" is a 4-bit number. data can be stored,
Here, data of the last digit of the number of copies for the document loading bin 9 or data of "F" representing that no document is placed in the loading bin is stored. I/0-1, I/0-2, and I/0-3 are input/output devices that receive data input signals such as whether there is a document in the bin or whether a copy has been made.
Alternatively, it generates a signal to drive a clutch and a solenoid for feeding a document, etc., and a detailed diagram thereof is shown in FIG. 7, and input/output device I/0-1,
FIG. 3 is a diagram showing connections between I/0-2, I/0-3 and peripheral circuits. In the figure, SW1 to SW5 are micro switches for detecting whether or not a document is placed in the document loading bins 9 to 5, and optical detection may be used. SW6 is a detection means, which is a microswitch that detects whether the document has arrived at a predetermined position. LD uses a detector to count the number of copies.
For example, it is used to detect light from an exposure process. IRP
is a detector that detects an interrupt, and performs other processing by detecting such a signal. DE1 is a decoder,
The output of the input/output device I/0-1 is decoded, and the pick-up roller shown in FIG. 1, which sends out the originals placed in the placing bins 5 to 9, is operated. For example, in the case of the loading bin 9, the pick-up roller 13 is operated. DE2 is a decoder, input/output device I/0-2
, and drives plunger solenoids SL-1 to SL-5 that drive guides that guide documents to document receiving bins 60 to 64. Solenoid SL
-1 activates the guide 65. TMR is a timer that operates with signals from input/output devices I/0-3, and transmits signals after a predetermined time to input/output devices I/O.
Returns to 0-3. A clutch Cl-f controls the conveyance of the document in the document conveyance section 3. The input/output device I/0-3 also sends a copy signal to the copying machine from the terminal Io. Another input/output device I/0- in Figure 4
A detailed diagram of 4 is shown in FIG. 9, and this input/output device outputs the keys necessary for setting the number of copies and the signal to control the display that displays the set number of copies. ) can be used. In the figure, "0", "1", . . . "9" are numerical keys, CL is a clear key, and OK is a number setting completion key. DP1 to DP5 display information regarding document placements 9 to 5. This device has a buffer register for circuit key control for the key I code, a shift register for storing display data, a digit signal generator for displaying the display data in a time-division manner, and the like. The CPU in Fig. 4 includes the memory, one or more registers AC and PC for specifying addresses of input/output devices, and one or more registers A, B, C, and other registers for primary storage.
D. Overflow Bit OVF, Frog CFT Control unit CT with addition/subtraction logic control for decoding data input from data signal line and processing data, arithmetic circuit ALU, This arithmetic circuit ALU performs data decimal correction, addition, and exclusive OR. Has a function. Note that the contents of register A can be rotated to the right (shifted to the right) or rotated to the left (shifted to the left). The CPU has the above circuits and is connected to the above external circuits through a plurality of lines. To give an overview, the CPU first specifies the address of the ROM where the sequence is programmed, the contents of the specified address are read into the CPU through the data signal line DB1, the CPU decodes this, and
According to the decoded contents, the data is processed within the CPU itself in chronological order from power-on, and the data in the CPU is stored at a specified address in RAM, or Inputs the data at the specified address into the CPU, and sometimes inputs the data in the CPU to the input/output section I/0-1~
Sequence control is performed by outputting to the signal line DB3 of I/0-4 and inputting the contents on the signal line DB3 of the input/output section into the CPU. The control means according to the present invention will be explained in detail below. First, the basic timing for sequence program processing will be explained with reference to the clock time chart in FIG. Each command of the program is pre-encoded and stored in 8 lines in the ROM, and the designation of each code is determined by decoding n codes from the address code bus line with an address decoder and out of 2n codes. The system is such that one is selected and output. This ROM and the address where the instruction in the ROM is stored are specified by a ROM address specifying register PC. This register PC is +
1 by the control signal α1, and programmed instructions are output one after another. This register PC is input to the ROM by multiplexers A to C at predetermined times. The ROM outputs the instruction code on eight lines, but since the data code bus DB1 has four lines, it is time-divided and output to the data code bus in two parts. The instruction codes output in two batches of 4 are SW9 and SW by 2 and 3 clock signals α.
6. The contents are latched in registers C and D by opening and closing of SW7, and the contents are decoded by an instruction decoder to generate a control signal α for processing according to the contents of this instruction. In short, as shown in Figure 10, it takes four basic clocks to complete the designation of the address where the program is stored and the decoding of the instruction code stored at that address, and then during the following six clock cycles. , executes the contents of the above instruction. Then, the programmed instructions following the address are executed again at similar time intervals. Therefore, it takes time equivalent to 10 clocks to execute one execution instruction (one step) in a programmed sequence. A 2-word instruction requires 20 clocks. Note that registers A and B are for calculations and are as follows.
It is called Acc, Tm. Each switch SW is a gate circuit controlled by a control signal α, and the OVF is a well-known circuit for detecting an overflow of the register Acc. Control unit CT decodes registers C and D and registers
This circuit calculates Acc and Tm and outputs the control signal α. The above configuration diagram and Figures 11 to 11 describe the operation of the control device shown in Figure 4, which has the above-described configuration.
This will be explained with reference to the operation diagram shown in FIG. 24. First, the instructions for each step shown in FIGS. 11 to 23 will be explained using the case of NEC's μCOM4. 1 0100 X1X2X3X4 address specification command
Y1Y2Y3Y4 Z1Z2Z3Z4 X1~4 to AC3, Y1~4 to AC2, Z1~
Transfer 4 to AC1. During program execution, a certain address in the ROM is specified by the PC, and at time T1, code 0100 is output to the data code bus line, and T2
It is latched to register C by opening and closing SW6 and SW9. Similarly, T2 decodes this and recognizes that it is an address specification instruction, and it continues with X1 at T2.
~4 is output to the bus bar, T3, SW9,
It is latched to register PB3 by opening and closing SW15. Next, add 1 to the PC and output the codes Y1-4 and Z1-4 of the following addresses in the ROM, store these in AC2 and AC1, and then write the new address you want to use in the later program to PB. Store.
This execution timing is slightly different from that in FIG. 2 0101 X1X2X3X4 Jump instruction
Y1Y2Y3Y4 Z1Z2Z3Z4 If the jump condition of X is met, the address to jump to
Transfers Y1 to 4 and Z1 to 4 to each AC2 and AC1, further transfers AC2 to PC2 and AC1 to PC1, and completes, but does not jump if not established. When X1 to 4 are 0010, jump instruction is executed when overflow OVF is detected as 1. When X1 to 4 is 0100, when register Acc is 0, when 1000 is unconditional, and when 1010 is
When OVF is 0.1100, this is a jump instruction when register Acc is not 0. First, at time T1 + T2, an address in the ROM is specified by the PC, at time T1 code 0101 is output to the data code bus, and at T2, register C is output by opening and closing SW6 and SW9.
is latched to. Same as T2, followed by X1~4
is output to the bus line and latched to resistor D by opening and closing SW7 and SW9 at T3. Now, X1~4=
If it is 0100, then at time T4, 0101,
It decodes the 0100 code, recognizes that it is a jump instruction, and determines the contents of register Acc, and then first reads the register at the time T5 to T10.
Determine whether the content of Acc is zero, and if it is not zero, add +2 to the PC and exit from the jump command.
If it is zero, add 1 to the PC and change the following codes Y1 to 4, Z1 to 4 in the ROM to SW9, SW11,
AC2 and AC1 respectively by opening and closing SW13.
Store in. Furthermore, AC2 → PC2, AC1 → PC1
Transfer to. This will change the jump destination address.
It appears on the PC, and in the next cycle from T1 to T10, a new address to jump to is specified in the ROM and the jump is completed. 3 0110 1000 Transfer instruction (1) This stores (hereinafter referred to as load) the data at the address specified by AC in register Acc. T1+T2
At the time T, an address in the ROM is specified on the PC, and
At time 1, code 0110 is output to the data code bus, and at time T2, it is latched into register C by opening and closing SW6 and SW9. Also continues with T2
1000 is output to the bus bar, and SW7,9 is output at T3.
It is latched to resistor D when it opens and closes. At T4, the codes in registers C and D are decoded, and from T5 to T1
At time 0, the AC code is output to the address code bus, the contents of any of the key registers of the RAM, output device, or key display input/output device specified by this address are output to the data code bus, and SW9, It is stored in register A by opening and closing SW2. Since it functions in a similar manner, it will be briefly described below.

【table】

[Table] The codes for setting the input/output devices and memory itself required in the following procedure for controlling by making full use of the above instruction codes are as follows. X means that the code is not limited.

[Table] That is, the top four of the 12 address code bus lines are lines for selecting memories, etc., and each memory and input/output device has a circuit known in itself for decoding this. The other eight lines are furthermore lines for specifying sub-addresses of the memory, each memory having a circuit known per se for decoding them. Each input/output unit in the input/output device corresponds to each 4-bit data digit in this example, so a special designation circuit is required. To explain the document handling operation, when a power switch (not shown) is turned on, step 1 shown in FIG. 11 begins. First, a flag register, a set number of copies register, a register for storing the number of copies, etc. in the memory RAM are set to predetermined values. For example, Figure 6B
The register WR(0) in the memory RAM shown in
Clear WR(1), WR(4), WR(7). In addition, RAM addresses “XO20”, “XO21”, “XO22”,
"XO23", "XO24", WA (0), "XO40",
Clear "XO41". Here, to explain the address again, for example, to explain the XO20 address, the first "02" indicates the row position, and the lowest digit "0" indicates the column position. For example, the street address
XO20 to XO24 store the order in which document receiving bins should be processed. Furthermore, if there are no originals in the original document placement bins 5 to 9, each of the bins 5 to 9
An indicator that shows that there is no document in 9.
In order to display "OF" on DP5 to DP1, RAM
"OFOFOFOFOF" data is set in XO30 to XO39. The contents of the RAM are determined in step 1 as described above. In the next Step 2, the contents of XO30 to XO39 are shown on the display.
Control is performed to send data to DP1 to DP5, details of which are shown in FIG. First, data "9" for selecting display devices DP1 to DP5 is stored in register WR (3). The number "9" is determined from the fact that the segment type displays DP1 to DP5 have 10 display bodies. In this case, the lower digits of the display DP5 are sequentially selected, and the lower digits of the current DP5 are selected.
Address information XO39 of the register to be displayed next is set in register AC and further in register WA (3). The address data of "XO39" of register WA (3) is set in register AC again, and the data of the set address is set in register Acc. Next, data "X500" for selecting input/output device I/0-4 is set in register AC, and the contents of register Acc are sent to the display register (not shown) of input/output device I/0-4. In this case, the content displayed on the input/output device I/0-4 is the aforementioned "F". Next, in order to select the upper display of display device DP5, the contents of registers WR (3) and WA (3) are subtracted, and as mentioned above, the data to be displayed in RAM is transferred from input/output device I/0 to Sent to 4. When the above steps are performed 10 times, the transfer of the display data to the input/output device I/0-4 is completed.
The input/output device I/0-4 displays the above data "OFOFOFOFOF". Next, control in Step 3 is performed to check whether the original is placed in the original placing bins 5 to 9. Micro switches SW5 to SW1 as detection means provided in the aforementioned document placement bins 5 to 9, respectively, convert the signals indicating the presence or absence of a document into electrical signals to the input/output devices I/0-1 and I/0-2. input/output device I/
Input to I0 to I3 of 0-2 and I3 of I/0-2 respectively, and input “1” (High Level) “0”
(Low Lovel) and decided that if it is "1", it is the condition that a manuscript is included, and I0 to I3 of I/0-2 (X'200)' and I/0-1 (X'100)' Distinguish which of I3 is "1" and in which order it becomes "1", and then enter the original document bin that was entered first.
Store NO at address XO20′. In other words, if I2 of input/output device I/0-2 is input first,
Store 2 at address X′O20′. The second input document placement bin number is stored at address X'O21'.
In this way, the document placement bin numbers are stored in the RAM from X'O20' to X'O24' according to the order in which copies should be made, and the copying order starts with the cassette number at address X'O20' first. X′O21′ to 2nd X′O22′ to 3rd
Do X'O23' in the 4th position and X'O24' in the 5th position. X′O20
Store a value of 0 indicating that there is no original content in ~X′O24′. As shown in the above control procedure in Figure 16, registers Acc and WR (3) are cleared, and register
Set "X200" to AC (this is the address data that selects input/output device I/0-2, and O20 is actually set to register AC), and set micro switch SW1 of input/output device I/0-2. ~The on/off state of SW4, ie, the data regarding the presence or absence of a document, is input into the register Acc. Next, in order to view the contents of register Acc, shift the overflow bit OVF by 1 bit by rotating to the left. Then, it is determined whether the overflow bit OVF is not 1 or not. If the result of this determination is not "1", the microswitch SW1 is informing that there is no document in the document placement bin 9. If the document is not in the document receiving bin 9, then in order to detect the state of the micro switch SW2 of the document placement bin 8,
The address of input/output device I/0-2 is register AC
microswitches SW1 to SW4.
Signals "1" and "0" indicating the state of the data are set in parallel in the register Acc via the data bus DB3.
Next, rotate the contents of register Acc twice, set the state of micro switch SW2 in the overflow bit OVF, and determine whether the overflow bit OVF is "1" or "0".If the document is not in the document receiving bin 8, , "0", so the next microswitch SW3 is checked, followed by microswitch SW4, in the same manner as described above. In this example, the micro switch installed in document placement bin 5
Since SW5 is provided in the input/output device I/0-1, when determining the microswitch SW5, the address "X100" of the input/output device I/0-1 is set in the register AC. If the manuscript is not included as described above, then
Key input control in Step 4 is performed. The detailed control means are shown in FIGS. 18 and 19. In the figure, first we look at the memory RAM registers.
The contents of WA(0) are sent to register WR(3) via register Acc. Now WA(0) contains the data of "XO20" as explained in step 1, so register WR(3) is "0" of "XO20".
is set. Next, "Set ADD" is performed as shown in FIG. First, RAM address data “XOoc”
is set in register AC. "XOoc" above
is register WR(3). Next, "1→Acc", that is, 1 is set in the register Acc. Next, "AccAc→Acc", that is, the contents of WR (3) and the contents of Acc are compared and stored in Acc, and it is determined whether the contents of register Acc are not 0 or not. Now it is "1", so next time register
The same thing as above is done by setting Acc to ``2'' instead of ``1'', and the same process is repeated until register Acc is set to ``5'', and ``Acc≠0''.
If so, exit Set ADD and set register WA (0)
The lowest digit address “XO03” is register AC
is stored in register Acc, and “4” is set in register Acc.
The least significant digit of register Acc and WA(0) are compared to determine whether register Acc is "0".
In this case, it is not "0", so the next step is WA (0)
→AC, AC _L →Acc, Acc→WR (3) changes the contents of the least significant digit of register WA (0) to register WR
(3) Stored in Next, it is determined whether the sheet number set flag is "1" or "0", and since it is not set in this case, key input control shown in FIG. 21 is entered. First, the address "X500" of the input/output device I/0-4 of the register AC is set, and a signal is taken in from the input/output device I/0-4 of the register Acc. The input/output device I/0-4 mentioned above is, for example, μPD757 manufactured by Nichiden.
When such a device is selected, it is first sent a 4-bit signal indicating whether a key is pressed, whether there is a key error, and which key input line. First, in order to determine whether the key is pressed down, rotate Acc counterclockwise and check the overflow bit.
Sends a signal to the OVF that a key is pressed.
Since no key is currently being operated, OVF≠1. Then, the data "D" generated by the ROM is set in the register Acc. The contents of register Acc are transferred to register WR (7). Therefore, the next step of Key in Figure 18, register
Address "XO1c" of WR (7) is set in register AC, D obtained from ROM is set in register Acc, and register WR (7) is set in ALU.
A comparison (exclusive OR) is made between the contents of the register Acc and the register Acc, and "0" is set in the register Acc.
Finish the KEY IN procedure in Step 4. Next, Step 5, a procedure for determining whether the setting of the number of copies of the original in the original receiving bin is complete, begins. That is, the RAM address "XO40" where the copy number setting flag is stored in register AC is set, and the contents of address "XO40" are stored in register Acc.
is set to Then, the contents of register Acc are rotated to the left (shifted to the left by 1 bit), and the contents of overflow bit OVF are checked. Since it is now "0", the display control returns to Step 2 again, and Steps 2 to 5 are repeated until the copy number setting is completed. Assuming that 5 originals have been placed on the original placing bin 6, the micro switch SW4 is turned on and the originals are placed in the original placing bin 6.
In Step 3 of the repetition, the following is detected. Micro switch as explained in Step 3 above
It is checked sequentially from SW1, and when micro switch SW4 is detected, "X200" is set in the register AC.
is set, micro switches SW1 to SW4
The state of is stored in register Acc. Next, in order to check the status of micro switch SW4, Acc is rotated clockwise (shifted 1 bit to the right) and the micro switch SW4 is checked.
The status signal of SW4 is set in the overflow bit OVF and judged. Now overflow bit OVF
is “1”, so the address “XO36” is the register
The contents of address “XO36” are stored in AC and the contents of address “XO36” are registered.
Transferred to Acc. The contents of the register Acc are then determined, and since it contains "0" as described above, the contents of the address "XO37" are retrieved next, which is "F" as described above. The complement "0" of such "F" is stored in register Acc, and register Acc
It is determined whether the content of is “Acc≠0”. Since it is "0" here as well, 4 is sent from the ROM to the register Acc, stored in the register WR (3), and the first
Memo control is performed, the details of which are shown in Figure 7. First, the address “XO00” of WR (0) is a register
AC, and then '0' is transferred to register Acc. Then, the ALU performs exclusive OR of the contents of registers WR (0) and Acc, and the result is stored in register Acc. Next, it is determined whether the contents of the register Acc are "0", and since it is now "0", the address "XO20" is stored in the register AC, and this address is further transferred to the register WA (3). Next, in order for "4" stored in register WR (3) to be stored in WA (3), WA (3) → AC, WR (3) →
Acc, Acc→AC is performed, Memo control is finished, and then the address "XO36" is set to register WA ( 3) and is stored in the first
Enter the SET control shown in Figure 7. First, the contents of register WR (0) are incremented by 1, and then the data “XO36” of WA (3) from earlier is added to the register.
Stored in AC, “1” of WR (0) is “XO36”
stored in the address. Also, at this time, "F" is set at address "XO37". Therefore "XO30" ~
The content of "XO39" becomes "OFOFOF1FOF". If the next key is not operated, the
When Step 4.5 is performed and the process returns to Step 2, the display DP4 displays "1F", and the other displays display "OF". After the original is placed in the original placing bin 6 as described above,
When the second document is set, for example, in the document receiving bin 9, the turning on of the micro switch SW1 is detected in the control of Step 3 as described above, and the control of Memo shown in FIG. 17 is performed in the same manner as described above. It will be done. However, there is a document receiving bin 9 in register WR (3).
Data "1" indicating the position of is stored.
When entering Memo control, first register WR (0)
You can check the contents. Since there is already a document in the document receiving bin 6, the content of register WR (0) is set to "1", so the second judgment of Memo control is yes and the address "XO21" is written to register WA (3). ” is stored, “1” of register WR (3) is stored at address “XO21”, and Memo control ends. Next, to notify that the original has been placed in the original bin 9 and that the original in the original bin 9 has been placed second.
Set "2" in "XO30" of RAM and "2" in register WR (0). As described above, the second document is placed in the document placement bin 9.
If nothing is done for a while after entering the screen, the document will be detected and the key will be detected as described above, and display control will be performed again.
Since the address contains the data "2FOFOF1FOF", the display DP1 displays "2F", the display DP4 displays "1F", and the others display "OF". Next, when the numerical keys 0 to 9 in Fig. 9 are operated,
In accordance with the control of KEYIN in Step 4, data on the number of copies in the document bin 6 set first is stored as follows. Suppose you now make 23 copies. First, in Step1, register WA (0) is "XO20"
Since data is stored, WA(0) →
Data "4" is set in register Acc by AC, AC→Acc. Next, the control of Set ADD shown in FIG. 20 is entered, and the address "XO37" containing the copy number setting data of the document holder 6 is entered in the register WA (1). Next, it is determined whether the number of copies has been set, and if it has not been set, the number of copies shown in Figure 21 is displayed.
Enters KEY control and determines numeric key operations.
As mentioned above, at this time, the input/output device I/0-4 first checks whether there is a 4-bit key (1 bit), whether there is a key error (1 bit), and which signal line (KR0 to
2 bits representing KR3) is output, and a judgment is made based on whether the specific bit is set to 1 or not. If it is not standing now, input/output device I/0-4
The numerical key data "5" is entered into registers Acc and WR (7). Next, it is determined which key was operated again,
If it is a numeric key, determine whether the current number is the first digit by checking the contents of register WR (1). Next, data "2" of register WR (7) is taken into register Acc, and data "2" of register WA (1) is taken into register Acc.
Register the data of "XO37" stored in
AC and store "2" in address XO37. Next, store "F" at address XO36, and store "2" in register WR to remember that it has been placed once.
Store in (1) and end KEY IN control. Since the setting completion key OK has not been operated yet, the display control is performed again, and this time the data of "2FOFOFF20F" is displayed on the displays DP1 to DP5. Next, when the numeric key "3" is operated, the KEY control shown in FIG. The th arbiter transfers the content "2" of register WR (1) to register Acc and performs right rotation (right shift) twice, that is, 1248
If it is a code, "2" is "0010", so
As a result, "1" precedes the overflow bit OVF, so the following control is performed. First, "2" stored in address "XO37" is transferred to "XO36", data "3" is stored in address "XO37", and "6" (i.e. 0110) is stored in register WR (1). and end KEYIN control.
With the current key input, the displays DP1 to DP5 become "2F", "OF", "OF", "23", and "OF". Since the setting completion key has not been operated yet, proceed to Steps 2.3 and 5.
control is repeated. Next, the above-mentioned sheet number data setting completion key is pressed. The KEY control of the KEYIN control is performed as described above, and when it is determined in the KEY control that the completion key has been operated, "F" is set in the register Acc and further set in the register WR (7). . The completion key OK operation check is checked twice in the same way as the numeric keys mentioned above, and the completion key is checked twice.
If OK, determine the contents of register WR (1), determine whether numerical data is set,
If set, "7" is register WR (1)
Then, in Setflag shown in Figure 22, put the last digit "0" of WA (0) in Acc,
Judge the contents of Acc, and enter "0", the last digit of "020" of WA (0), into Acc in order to remember that the completion key OK was operated. "1" is stored in the most significant bit of the address. Next, when the numeric key and completion key are operated, the contents of WA (0) will be "021", so the last digit "1" will move to the next bit after the most significant bit of address "XO40". Set "1". As described above, a flag is set at address "XO40" and control in Step 5 is performed. That is, "XO40"
The most significant bit of the address is input to the overflow bit OVF, and the control circuit CT determines whether "OVF≠1". Since it is currently 1, proceed to Step 6. First, register WA (4), which stores count data of the number of copies, is cleared. Next, the NO of the document placement bin at address "XO20" is stored in register WR (2). No. 1 to 5 are assigned to document placement bins 9 to 5. Therefore, "4" is stored in WA(2). Next, control in Step 7 begins. First, address “XO08” of WR (2) is set to register AC, then “8” is set to register Acc.
The data is transferred from the ROM, and Acc+WR(2)→Acc is performed. Next, the address "X100" of input/output device I/0-1 is set in register AC, and
"12" or "D" in Acc is sent to input/output device I/0-4, and terminals Q ₃ to _{Q 0} of I/0-4
``1100'' appears in the gate, the most significant bit signal opens gates AG1 to AG5, and ``100'' opens decoder DE1.
is applied to the other input terminal of the AND gate AG4, thereby driving the clutch cl-4 and leading out one document from the document placement bin 6. Next, so that the original is sent to the copying machine, address "X300" is set in register AC, 2 is set in register Acc, and clutch cl-f is driven in the same way as I/0-1. The ON time of the clutch cl-1 above is the timer TMR.
It is set in advance by , and it is turned off when it is sent out. Next, in step 8, the detection means SW6 detects whether the document has reached a predetermined position. Such detection means
SW6 is 52 or 53 shown in FIG.
During this control, the copy number setting for the document placed in the document bin 9 is detected. For example, when a numeric key is operated to set the number of copies to 9, the address "XO20" stored in register WA (0), which stores the order in which documents were placed in the document placement bin, is changed to "XO21". changes depending on the flag at address “XO40”. Next, when the KEYIN control is entered again, the number of sheets for the originals in the original placing bin 6 is set to "2".
Same as the numeric value, but since the data stored in register WA (0) is "XO21",
Data of “9” is entered at address “XO31” and “XO32”
The data “F” is entered in the address. Furthermore, if the setting completion key is operated, the RAM number setting flags "040" and "041" are set to "1" in the same way as the above operation. This time, the copy order is second, so "040"
The weight bit of address "4" becomes "1". If it is determined in Step 8 that the document has arrived at the predetermined position on the document table after the key operation for setting the number of sheets for the document in the document placement bin 9 as described above, the clutch cl.
-f is turned off, movement of the original is stopped, and a copy start signal is outputted from the input/output device I/0-3 to cause the copying machine to copy the original. In addition, step 8
Also, the document detection control means ORG (16th
Similar to step 3 described above, the key input control procedure KEY IN (Fig. 18, Fig. 19)
As in step 4 described above, the number of sheets for the newly set original is set. In the next Step 9, the copying device charges, exposes,
Each process of development, transfer, and fixing continues, but the light from the light source of the copying device during the exposure process is detected and control is performed to count the number of copies based on the number of blinks. Check the detection signal (Lamp Detect) of this light source. Also, as in Step 8, input and display the setting keys for other cassettes while checking. When light is detected, one copy has been completed. The above copy detection control is performed using the input/output control I/0-
The signal of the detection means LD input to the terminal _I1 of 1 is checked, and when it is ``1'', it is assumed that one sheet of copying has been completed. Above mentioned input/output device I/0
When the contents of terminals I ₃ to I ₀ of -1 are sent to register Acc and the contents of register Acc are right-shifted twice, the state of terminal I ₁ is set to overbit OVF,
If the content is "OVF≠1", it indicates whether a new document has been placed in the document receiving bin, whether a key operation has been performed, and whether the display control of the contents of addresses "XO30" to "XO39" in RAM is as described above. “1” from the detection means LD
This is repeated until it appears. That is, step 8,
The document detection control means ORG (FIG. 16) in step 9 detects whether or not a document has been newly set in the document placement bin in the same way as in step 3 described above, and executes the key input control procedure KEY IN (FIG. 18, 19), the number of sheets for the newly set document is set in the same manner as step 4 described above. Then, in step 15, the newly set original is continuously copied by the set number of sheets after the previous original has been copied, as will be described later. When "1" appears at the terminal I1 of I/O- ₁ , the contents of the register Acc are rotated to the left (shifted once to the left), and then in step 10, the interrupt signal sent from the copying machine is applied to the terminal I. A state of ₀ is determined. If it is "1", it means that an interrupt has occurred, and this means that when you urgently want to copy just one sheet or several sheets, press the copy button on the copying device or press the interrupt request button to send the I/O to the copying device. It is input to the terminal _I0 of 1.
When this is detected, the control device holds the current state as it is, waits for the interrupt signal to end, and then enters Step 11. If there is no interrupt signal, the copy number counting operation in Step 11 and the comparison of the set number of copies are performed immediately. Details of CNT, which is a routine for counting the number of copies and comparing the set number of copies, are shown in FIG. If we explain according to the same figure, register WA
(4) is cleared in Step 4, and the lowest digit "0" of register WA (4) is set in register Acc, +1 is performed in ALU, the addition result is stored in Acc, and the contents of Acc are further stored in ALU. is corrected in decimal form, and the contents of Acc are sent to AC3 of register AC. Next, the overflow bit OVF is set to “OVF≠
1". Since "OVF≠1" now, in order to retrieve the data at addresses "XO30" to "XO39" where the copy number setting data is stored, the contents of register WR (2) are retrieved. Check whether the content is from 1 to 5. Since the data of "4" is now in WA (2), the data of "XO37" enters WA (2), and then enters the register AC, and the data "3" stored at address "XO37" is stored in WA (2). The register Acc is derived. Next, the data of the least significant digit of register WA4 is derived and compared with the contents of register Acc. Now Acc
≠0, so go, clear Acc, and then
Clear WR (3) and end CNT control. Next, the contents of register WR (3) are transferred to Acc, and it is determined that "Acc=0". In this case, the answer is yes, so we return to Step 9, which controls document detection, etc.
Since the copy start button is currently on, the copying machine continues to copy the original placed on the document table, and when the content of the lowest digit of register WA (4) reaches "3", "XO37" for CNT control
When comparing the contents of the address and the contents of the lowest digit of WA4, "Acc≠0" is no longer true, so instead of going to "XO37" in WA (2), change the address data of "XO37" to "XO36" and write "XO36". Address details and WA (2)
Compare the contents of address “XO12” of
When the control procedures of Steps 9, 10, and 11 are performed and "23" is stored in WA (2), it matches the "23" stored in "XO36" and "XO37", so the last control of CNT Set 1 to WR and write the contents to WR.
(3), and the final determination of Acc=0 in Step 11 yields NO, and control in Step 12 is performed. That is, in order to send a copy signal OFF "0" to the terminal 0 of the input/output device I/0-3, and to replace the original on the original table of the copying machine 37 with the next original, the driving means of the original transport unit 3 is activated. Clutches cl-f are actuated and the document begins to move. Next, the document receiving bin 64
In order to put a copied original into the bins 64-60, guide levers 65 and the like are driven by solenoids SL-1 to SL-5, and send the original to the original receiving bins 64-60. Note that the solenoid SL-1 acts on the document receiving bin 64, and the solenoid SL-2 acts on the document receiving bin 63.
Now, connect the clutch cl-4 to the document placement bin 6 mentioned above.
The solenoid SL-4 is activated in the same manner as when the previous document is stored in the document receiving bin 61. When the above operation is completed, the control goes to Step 13,
First, check whether there is a document in the current document placement bin 6 by inputting I ₀ , I ₁ , I ₂ , I ₃ of input device I/0-1 and I ₃ of input device I/0-2. I'll investigate.
Since the original is now in the original placing bin 6, the process returns to Step 7 and the same operation as described above begins.
When copying is completed for the 5 originals contained in the storage, Step 14 is entered, and the register WR, which records the number of original bins currently containing originals, is entered.
Subtract 1 from the contents of (0). It was now "2", so it becomes "1". Next, since there are no more originals in the original placing bin 6, register WR (2) is used to change the "23" displayed on the display DP4 to "OF".
Take out "4" from , set the address of "XO37" to register WA (1) under ADD control, put "F" depending on the address of "XO37" above, and set "XO37" to "XO36". control to input "0" into address "XO36". Next, control is performed to shift the contents of "XO20" to "XO25" to the left, and finally, control is performed to set "0" at address "XO24", thereby ending Step 14. Next, in Step 15, the contents of addresses "XO40" and "XO41" are shifted to the left by 1 bit, and register WA4, which counts the number of copies, is reset, and if register WR (0) is "0", Step 1 is executed. Return, if the contents of WR (2) are not 0, the original is in one of the original loading bins, so
Returning to Step 6, control is performed on the original in the original placing bin to be copied next. mentioned above
In Step 14, since the address "XO20" contains the data "1" indicating the document placement bin 9, the document placement bin 9 is controlled as described above. FIG. 24 is a diagram showing the operation timing of the clutch, solenoid, etc. in this embodiment described above. In the above example, the number of copies was shown as an example of the copy condition, but conditions such as copy density can also be set in the same way. As described above, according to the present invention, while performing a processing operation on a certain document, the processing conditions for another document are stored, thereby making it possible to quickly perform the document processing operation. Further, according to the present invention, storage control of processing conditions is performed in accordance with document detection.
For example, it is possible to prevent waste from being reserved for document processing even though there is no document to be actually processed.
