Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a copying apparatus, and more particularly to a copying apparatus equipped with a multi-stage document mounting table and capable of reserving copying conditions such as the number of copies for each document.

Reservations for copying conditions for each conventional technique are stored in a storage means within the copying apparatus. Even if there are no originals on the original table, the contents stored in the storage means remain, which is inconvenient for operation.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a copying apparatus that automatically clears the reserved copying conditions for the original when there is no original on the original table.

Structure of the Invention The copying apparatus of the present invention includes a plurality of document placement tables on which a plurality of document groups are placed, a document feeder capable of reserving copying conditions for each document group, and a copying device configured to set the above-mentioned reservation conditions for each document group. a storage means for storing copying conditions set for each original document mounting table; a document detecting means for detecting the presence or absence of a document provided for each document placing table; , means for erasing the copying conditions stored in the storage means.

With this configuration, the copying conditions reserved and stored for each group of originals are automatically cleared by the signal from the original detecting means.

Example An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention. In the figure, 150 is the main body of the copying machine, which is a circulating automatic document feeder (hereinafter referred to as ADF) that has a bidirectional linear conveyance path on the document table l.
151 are installed. 152 is a multistage feeding device, A4. B4. B5゜... Paper of different sizes can be placed. 153 is a drum-shaped photoreceptor;
A charger, an eraser, a developer, etc. necessary for the copying process, which are not particularly shown, are arranged around it. 154
1 is a fixing device, and 155 is a copy paper output tray.

Between the fixing device 154 and the output tray 155, there is a slip sheet insertion unit 156 for partitioning each group of copies corresponding to the original, and in FIG. 1 there are two types of rolled slip sheets 157.
．． 158 are available.

On the other hand, as shown in FIG. 2, the operation panel section has numeric keys 159 from O to 9, function keys 160 from F0 to F3, a display section 170 that shows copying conditions, and a display window 161 that shows the job status of each row of the document tray. provided.

When a copy is reserved, the display window 161 displays, for example, orange,
When copying is completed, a blue lamp will be displayed, and if it is empty, a green lamp will be displayed.

The display section 170 includes a display 170a indicating the selected document tray stage, a document number display 170b, a copy number display 170c, and a time display 171. For example, a 7-segment liquid crystal display device is used for each display.

It is possible to programmatically reserve the number of copies of the original on which stage of the multi-stage original tray shown in FIG. 1 to be copied.

Fo is the size code (e.g. A4-1.B4-2),
IFI is the number of copies, F is the number of sheets, F,
indicates the number of ADF stages.

For example, 15 copies of 5 sheets of the original in the 1st row of A4, 20 copies of 3 sheets of the original in the 2nd row, and 84 copies of 10 sheets of the original in the 3rd row.
When copying 5 copies of 7 originals in the 4th row at 84, 1-FO~15~F1~5~F,~1,,F.

1 = F o~20~F1~3~F! ~2~F32~
Fo~5~F1~lO~F,~3~F.

Reservations can be made by entering 2~F0~7~F1~7~F, ~4~F3, but these complicated operations can be saved especially when the same user wants to copy the same number of copies of several types of originals. For example, by placing a group of manuscripts on each column,
If you want to copy 7 copies each, enter "7~F,~F,". In other words, if you do not specify the number of stages, check the presence or absence of originals on each original platen and the reservation status, and check the originals placed above from last winter. The same number of copies shall be made for all documents. Also,
When copying only one copy of a whole group of manuscripts, the number of copies is usually “
Since it is initialized to “F3”
If you manually input only the `` key, you can input instructions for copying all parts of the document.Furthermore, if you place the original on an empty level and press ``F3'', it will automatically determine which level it is on and reserve the first copy. becomes.

As mentioned above, in the present invention, there is no column specification, and by loading multiple document groups on multiple columns and inputting the "F3" key (column cut, reservation registration), copies are made according to the reservation order for each column set in advance. This makes it possible to save labor when copying under the same conditions or making reservations in the initial mode (copying conditions). Although this apparatus has a copying end time splitting function, if the number of originals key is not input as in the above example, the preview function is disabled and splitting is not performed.

On the other hand, the feeding unit section is as shown in Fig. 3, and the trays 2a to 2d on the right side of the figure are multi-stage document trays (see Figs. 4 and 5 for details of part of the trays). , they are attached to the frame 40 with helical cam shafts 41 and 42 and bearings 43 and 44.
, are engaged via pins 45, etc., and the helical cam shaft 4
1.42 is driven by a stepping motor 46. The positions of the trays 2a to 2d are determined by the number of manual pulses of the stepping motor 46, and the originals are fed and ejected, and each tray has three positions accordingly. That is, if we focus on the tray 2b in FIG. 3(a),
Tray 2b is being fed upward by the feed roller 4 (first position), and in FIG. (second position), as shown in Figure 3(a),
(b) constitutes a circulation type ADF having a straight conveyance path. In addition, in the same figure (c), when collecting the document collection on the tray 13 all at once to the tray 2b (the third
position). Furthermore, as shown in Figure 3, tray 1
3 also has the positions shown in (a), (b), and (c) in the same figure, and is controlled by a stepping motor 48. A partial perspective view of the tray 13 is shown in FIG. Its structure is almost the same as that of the tray 2 part shown in FIG.
b. Further, a motor 52 is coupled to the roller 51b.

The circuit configuration of this system is shown in Figure 6.
80. Copy machine CPU'81. It consists of an ADFCPU 82, and each CPU has a built-in serial data transfer interface so that serial data can be sent and received between the CPUs.

In addition, each CPU has a memory of RAM83 to 85, and the operation unit CPU8Q has IO controllers 86 and 7.
Display controller for seg display 87.88
(Displ, Disp 2 ~ e.g. μPD82
When display data is sent to something like 79C-5 (NEC), it has the function of converting it to 7 seg display and displaying it. )
are connected, the first display section 87 is for displaying the time, and the second display section 88 is for displaying the number of copies (9 rows) and the number of copies lost. 10 controller 86 has a matrix configuration of numeric keypad and function key inputs, and the states of these keys are P.
A.

The signal is input to the IO controller 86 through the PB debo. Also, the PC boat is an output boat, and one of the original trays.
Displays for displaying the document status are connected to the 4th to 4th rows. In addition, the PD boat is an IC unit for watches, for example,
The MSM5832R3 is connected to a clock IC that can read and write time, and exchanges time data with the operating unit CPU 80 via the IO controller 86.

The copying machine CPU 81 is coupled to enable data transfer between each element control section of the copying machine, but this is not particularly shown. The ADFCPU 82 can receive input from various sensors and output signals to various drive units ■0
It includes a controller 89. The clock pulse generation terminal of the copying machine CPU81, which is the host CPU, is connected to the copying machine CPU81, the operation unit CPU80. It is connected to each clock pulse input terminal of ADPCPU82, and
The serial out terminal of the copying machine CPU is connected to the serial in terminal of each CPU, and the OUT terminal of the copying machine CPU is connected to the interrupt terminal INT of each CPU.
Data transfer is performed between t2, and each CPU takes in and sends only the necessary data based on its option code.

The transfer format of the above data is as follows.

Next, regarding the handling of reservation data, Figures 9-1 to 9-
The operation unit CPU 80 will be explained according to the flowchart in FIG. First, when the power is turned on to the operation unit CPU, it is initialized and the memory display digit counter etc. are cleared.

Next, the CPU will have enough time to communicate (several 10 m5
ec), reads the data from the ADF'CPU 82, receives the state of the presence or absence of originals in each row and the copying state from the copying machine CPU 8, and controls the lighting of the display based on these. Next, clear the reserved memory for the empty document tray. The detailed flow of the clearing part is shown in FIG. 9-6, and will be explained below.

The status of switches 18 and 19 is determined from the communication data by the operating unit CP.
It is taken into the accumulator ACC of U80, hexadecimal OR is performed, the second and subsequent stages are masked, and hexadecimal EE is subtracted from the result.

It is determined whether the result is 0 or not. CP determines whether it is O or not.
This can be done by looking at the zero flag of U, and the fact that the result is zero means that switch 18=0 and switch 19=0, both of which indicate that there is no document. This clears the first stage reserved memory area.

In this way, the memories of the second to fourth stages can be cleared in the same way, and the initial mode is set.

Numeric key input judgment Returning to Figure 9-1, from these initial modes, output “L” to the “0” bit of the 10FB boat, take in the 8 bits of the PA boat status, and check if any bit is “ It is determined whether or not the bit has become "L", and if either is "L", it is assumed that there is a key-in, and the bit counter is used to determine which bit has become "L".

For example, when "3" is keyed in, the PA boat status signal is b7bs bs b, b, b, b, b++
ZERO7'5gu! This state signal is taken into the accumulator (Ace). If you shift sequentially to the right, you will start from the 0th time,
At the third time (counter value), the zero flag is set, and the counter is "3", so proceed to the following routine, check what digit it is on the display digit counter, and if the digit counter is not 1, it will be the first digit. Key Manually input the bit counter value “3” to register 1 for displaying the I digit in RAM 83.
is stored, the digit counter is incremented by 1, and the display data and digit data are output to the second display section 87. In the above example, we described the judgment of numeric keys "0 to 7", but as shown in the flow for "8" and "9", <10 Outputs "L" from the controller PBl boat, checks the state of the PA boat, and uses the baby bit counter. By setting it to 8, the human power of the numeric keypad is detected in the same way.In addition, in the case of two-digit input, the first number keyed in is transferred to the display register for the second digit, and then the number keyed in later is transferred to the first digit display register. Store it in the display register. In this example, input of two or more digits is prohibited.

Next, check the function keys by checking the status of ■0 controller PA2~5 boats from Figure 6 and
It is determined which one of 3 has been pressed, and the previously input numerical value of the display counter is transferred and stored in the memory areas MO to M3.

Display method As shown in Figures 9-1 and 9-2, when F3 is pressed, it is assumed that a series of reservation operations have been completed, and the reservation completion indicator light for the number of steps stored in M3 is displayed through the PCO boat. be done. For example, if the 1.2nd stage has already been copied and reserved for the 3rd stage, and the 4th stage is empty, the display example shown in Figure 1θ will be output from the PC board, and the cycle will be A lighting display is made by repeated signals. When the display is finished, the number of rows is stored in a reserved memory area determined according to the value of M3 as shown below.

Reservation flag size Number of copies Required time for copies End 1st row

M31 M32 M33 M34. M35 4th stage M40 M41 M42 M43
M44 M45 data memory Reservation calculations are performed according to these reservation contents.

When F3 is keyed in, it is determined whether the display data is 0 or not, and if it is 0, the Ml data of each memory area is transferred to the number of copies reservation memory area M, ~M41 of each stage, and the reservation flag Mlo of each stage is set. Mt. .

The processing time Ti for each reservation group is calculated and stored in each area. On the other hand, based on the data from the copier cpugt, it is determined whether or not the remaining copy processing is required, and the remaining processing time is calculated. calculate.

When all of these calculations are completed, they are all added together to calculate the total time ΣT.

Next, the current time is determined by giving the clock IC the CLOCK address from the 0 controller PD board and reading the READ button.
Reading is performed by setting the terminal to "H", and the current time data is taken into the operating unit CPU (it is read out as O hour Δ minute).

By adding ΣT to this current time, the end time of copying the reservation is calculated. (Value of 0 hours x minutes) This calculation result data is automatically sent to the end time memory area 87 for each stage, and the time is displayed in advance.

Next, the above-mentioned CPU-to-data copier determines from the "Busy" signal whether or not the copying process is currently in progress, and
If not usy, end time t1~1 from reserved memory
．． (scheduled), those copy data blocks are placed on the communication data and transferred, the reservation flag is cleared, the original routine is again returned, and the above-described operations are repeated. Thereafter, by removing the original that has been copied, the copy reservation data in the operation CPU section 80 is cleared.

On the other hand, the copying machine CPU 81 performs data transfer/copy processing as shown in the flowchart of FIG.

The copying machine CPU 81 transfers its own data to the operating unit CPU 80 . The data is transmitted to each ADFCPU 82, and each data is received and stored in the RAM 84. Then, it is determined whether or not there is reservation data from the data sent from the operation unit cpuso, and if there is no reservation data, the copying machine is initialized,
Also, since data transfer is to be performed, the same routine as above is entered and waits until reserved data arrives. If reserved data exists, set Busy and input new data to the operation unit CP.
Call U80. Then, it waits for a print signal to come from the ADFCPU 82 and enters the copying process, and performs the copying process while transferring data until the reserved number of copies is completed.When the number of remaining copies reaches -0, Busy is reset and the process returns to the first routine.

In such a configuration, when the operator places a document on the multi-stage document tray and makes a program reservation as described above, the job display window 161 changes from green to orange. The copying machine displays the time at which the copy reserved for the current program will be completed based on the reservation program and copying processing speed registered in the internal memory, for example, as shown in FIG.

(10:25 in the figure) Regarding the subsequent document feeding relationship, the operation of the ADFCPU will be explained according to the flowchart of FIG.

First, receive the transmission data from the operation unit CPU,
It is determined whether the number of stages is specified and the ADFC
When the specified number of stages, number of copies, etc. are sent to the PU, the presence or absence of the original on the tray is detected by 5W1B, and if the copying machine is not BUSY, the feeding print routine is entered, but the feeding section selects two modes A and B. The document is fed from tray 2 and transferred to tray 13.
Mode A for discharging from tray I3, feeding from tray I3,
It can be divided into mode B, which discharges Each mode is summarized in the table below.

In the flowchart of FIG. 8, it is determined whether there is a document in tray 2 or tray 13, and mode A or B is set depending on which one.

Now, when the original is in tray 2, switch 18 is turned on.
At step Sl+, mode A is set and a paper feed signal from the copying machine is awaited. When the paper feed signal comes, the rotary solenoid 24 rotates in the direction of the arrow 31 in ONL, Figure 3a,
The belt conveyance motor 12 also rotates as indicated by the ONL arrow 32, and the stopper 10 is also turned on. When the lowest document is sent out by the feed roller 4 and passes the pair of rollers 7 while being prevented from double feeding by the Sabaki roller 6, the sensor 32 detects that the ONt motor 30 is at 0FFL and the feed roller 4 is stopped. The fed document is further fed by rollers 7 and belt 9.

When the sensor 11 is turned on, the motor 12 is turned off, the document is stopped at the stopper IO, a print signal is sent to the copying machine, and the copying end signal is waited for from the copying machine. When the end signal comes, the stopper lO is turned off and the motor 12. The ONL rollers 14 and 15 of the motor 35 rotate as shown by the arrows in FIG. 1 to eject the original onto the tray 13. When the document passes the sensor 11, a timer is turned ON for a time long enough to eject the entire document onto the tray 13, and when this timer is turned OFF, the belt conveyance motors 12 and 35 are turned OFF.
LWaits for the next paper feed signal. There is no switch here, tray 2
Repeat until there are no more manuscripts left.

When all the originals on tray 2 are finished, one copy has been completed and the switch 18 is turned off.

When the final copy is made and the ejection switch 162 is turned ON-OFF, the first rolled interleaving paper 157 is transferred to the pair of pinch rollers 1.
63, cut to an appropriate length by a cutter 164, and discharged by a roller 165 to be placed on the final copy paper.

As a result, the second set of copies is sorted, and the ejection switch 62 is turned on and off depending on the cut slip sheet.
Then, the second copy operation routine begins. By turning on the switch 19, the mode is set to B (the rotation of the motor is set in the opposite direction to the direction A), the rotary solenoid 24 is turned off, the lever 20 is at 20°, and the Sabaki roller 6 is pushed up by the cam slope 28. It will be done. The belt 36 is made of an elastic belt and is stretchable. When a paper feed signal is received in this state, the rotary solenoid 34 turns ONL as shown in Figure 2, and the paper feed motor 35. When the belt conveyor starter 12 is turned on and the paper is fed and the sensor 11 is turned on and off (that is, the original passes the sensor), the stopper 10 is turned on after a certain period of time.
The L belt conveyance motor 12 rotates in reverse. When the document turns on sensor 11 again, the belt conveyance motor 12 is turned off and the document stops at the stopper position. Send the print signal, and the motor is turned ONL by the print end signal.
The original is discharged onto the tray 2 and the switch 19 is turned to 0FF1, that is, the process is repeated until the original on the original tray 13 is exhausted, and the required number of copies, such as 3 and 4 copies, are further copied. When the required number of copies is copied and the specified number of copies ni and the number of copies no match, n
It is determined whether o is an odd number or an even number, and if it is an even number, the copying is completed and the process returns to 5TART to wait for the next designation. On the other hand, if the number is odd, the stepping motor 4 is moved to the third position where the originals on the tray 13 are ejected all at once.
6 is turned ON, tray 2 stops moving, and solenoid 49 is turned OFF.
By pressing N, the original pressure bonding is released. The tray 13 is also moved and stopped at the third position by rotating the stepping motor 48, and is released by turning on the solenoid 53. Next, the motors 52, 35, 12 are turned on, and the originals on the tray 13 are collected into the tray 2 all at once. After moving to tray 2, turn the detection switch 18 on the tray to O.
The motors 52, 35, and 12 are turned off to complete the copying process.

Next, a second slip sheet 158 passes through a roller 166, is cut by a cutter 164, is sent out by a roller 165, and is placed on the copy to serve as a partition of the document collection. When the ejection switch 162 is turned ON and OFF for this interleaving sheet, copying operation for the next reserved document collection starts and the same routine is repeated thereafter.

In this embodiment, there are two types of slip sheets. The reason for this is that it is easy to understand if the colors and shapes differ for each number of copies or for each manuscript collection, and even for one type, it is possible to differentiate by changing the length, etc.

In addition, in this embodiment, the copy ejection tray and slip sheets were used to distinguish between the originals, but if the conventional method of sorting using a sorter is acceptable, the original feeding mode may be a circulation type. It is not necessary to have one, and when connecting a sorter, it is also possible to cancel the circulation type.

Furthermore, in this embodiment, the reservation example is the number of manuscripts with one sheet.

Although the number of copies has been shown, it goes without saying that functions such as magnification and paper size can also be added as a reservation function.

In the above-described embodiment, the end time of copying is determined, but it is also possible to determine the copying order by determining the time when the reservation is entered and determining the copying order earlier or later than that time. In that case, the flow is 9-5.
As shown in the figure, the reservation time is stored in the reservation time memory area MI6. The order may be determined by importing M26, M2O, and M2S and placing them as t l''''' t 4.

Effects of the Invention As detailed above, according to the present invention, when an original is removed from the original placing table, the stored copying conditions for that original are automatically cleared, so that the reserved copying can be performed every time the original runs out. Operations such as deleting conditions are no longer necessary.
Operation becomes easier.
