Abstract

PURPOSE:To enable prevention of misoperation, such as feed of unnecessary slip sheet, by inhibiting slip sheet insertion when original processing modes and sorter modes except an automatic original feed mode are designated. CONSTITUTION:When copies remain on a paper ejection tray or in a sorter bin, and a slip sheet is fed, and the remaining copies are discriminated from the next copies, a sorter use mode is designated, and an original processing mode (SADF mode) except an automatic original feed mode is designated. At that time, the automatic slip sheet insertion mode is neglected, and flow to ordinary copy routine is selected. As a result, unnecessary slip sheet insertion can be prevented even if an operator forgets changeover operation of the automatic slip sheet insertion mode.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a control device for a copying machine equipped with a sorter.

(Prior art) In a copying machine, when there are remaining copies in the output tray or sorting turbine, the remaining copy paper is distinguished from the next output copy paper by feeding a liner. If you do this, the gold paper will be sent before the next copying operation, so if you forget to turn off the automatic liner insertion mode when performing the sort mode in the pressure plate mode or 5ADF mode (modes other than automatic document feed mode), the original The mount was being fed every time the paper was changed. Furthermore, it is not possible to distinguish whether there is a remaining copy of the previous worker or a copy that is in the process of being copied by the same worker.

(Purpose) Main F! AFi was developed in view of the shortcomings of the conventional methods.When there are remaining copies in the paper output tray or sorter, in a copier that can insert a liner before the next copy, the next copy mode is set. When the machine is in sorter or (press plate or 5ADF) mode, the insertion of a mount is prohibited to prevent operational errors such as sending unnecessary gold paper.

(composition) The configuration of the present invention will be explained below based on the illustrated embodiments.

Component is the main body of the copying machine, 2 is a sorter with multiple pins, 3 is an automatic document feeder that feeds multiple documents one by one to the exposure section, 4 is a sorter with multiple pins.
5 is a display unit, and 46 is a paper discharge tray for discharging copy paper.

FIG. 2 is a detailed front view of the operating section 4. 6-8 is 100

20 is a selection key for selecting trays 1 to 3 provided in the main body 1 that can accommodate multiple sizes, 21 to 23 are press confirmation indicators, and 24.25 is for selecting the sort mode or stack mode of the sorter 2. Keys 27 and 28 are confirmation indicators thereof, 26 are keys for inputting the automatic mount insertion mode by pressing the keys, and 29 are confirmation indicators.

FIG. 3 is a partially detailed front view of the display section 5. As shown in FIG. 3° Paper ejection tray overflow indicator lights up temporarily,
31 is a sorter confirmation display that lights up when there is residual copy paper in the sorter when the sorter overflows or is not in automatic liner insertion mode, and 32 is a jam indicator that lights up when a jam occurs in the main body or in the automatic document feeder. It is a display.

FIG. 4 shows part of the contents of the RAM in the control section 33, which will be described later. Paper output tray and previous copy size on the sorting turbine, paper size in tray 1, paper size in tray 2, paper size in tray 3, automatic liner insertion mode flag F0, ADF mode flag F1, sorting turbine overflow F2, Output tray overflow Fa
, sorter use flag F4, next copy number, selected tray N0, etc. are stored.

FIG. 5 is a block diagram of the control section 33. 34 is an 8-bit μCPU, 35 is a keyboard/display interface, 36 is a block diagram of the operation unit 4 and display unit 5, 37 is an R in which a control program is stored, and 0M138 is the aforementioned RAM.
, 39, 4.0 is ■10 interface, 41-43
and 44 and 45 are examples of the photo sensor and lead 8w used in the paper discharge tray, the paper detector in the sorter turbine, the paper size sensor in the paper feed tray, the paper discharge tray, the sorter pin overflow sensor, and the like.

Part of the control content of the control device 34 is shown in flowchart No. 6.
This will be explained with reference to FIGS.

Figure 6 shows whether the sorter is in use mode before entering the copy routine, whether the sorter pins are overflowing, whether the automatic document feeder (ADF) is in use mode, whether there is any copy paper remaining on the sorter turbine, and whether the It is novel that the paper sizes used in the copying operations used in the copying operation are unequal. If the sorter use flag F4=0, the process continues to ■, that is, the flow shown in FIG. 7, and if the sorter turbine overflow F2=1, the sorter confirmation display 31 is lit. If ADF mode flag F1 = 0, it is not the ADF use mode, so regardless of whether or not the automatic backing sheet insertion mode key is input, the automatic interleaf sheet insertion mode is ignored and the process continues to the normal copy routine.If there is no copy paper on the sorting turbine. , and if the previous copy size, ie the copy size remaining on the bin, and the next copy size are not equal, the normal copy routine continues. When the copy size remaining on the bin is equal to the next copy size,
A size comparison is made between the copy size of the bin and the sizes in paper feed trays 1 to 3, and when there is too much paper in the paper feed tray that is larger than the size of the remaining copy paper on the bin, the automatic interleaving paper insertion flag F, = Heart at 0.

If there is a paper larger than the remaining copy paper size in the 18 paper feed tray, and the automatic insertion flag Fo = 1, the sorter/confirmation display 31 will light up. Send the smallest paper that is larger than the paper size. Since the mode is ADF mode, the automatic mount insertion mode flag is immediately reset to prevent unnecessary insertion of mount paper.

FIG. 7 is a flow following FIG. 6 (■). Paper discharge tray overflow flag F2=O1 It is determined whether there is a copy on the paper discharge tray, whether the remaining copy size on the paper discharge tray is not equal to the size to be copied next, and so on. When the paper discharge tray overflow flag F2=1, the paper discharge tray confirmation display 30 is lit. If there is no remaining copy on the output tray, or if the size of the previously copied copy remaining on the output tray is different from the size of the next copy to be copied, the normal copy routine continues. When the two sizes are equal, the automatic liner insertion mode is determined, and if the mode is input, the copy paper size that was previously copied and remains on the output tray and the paper in paper trays 1 to 3 are Compare the size relationship. Next, if the paper size on the paper discharge tray is greater than or equal to the paper size in paper feed trays 1 to 3, the process continues to the normal copy routine.

In other words, when there is no gold paper available, the automatic mount insertion mode can be ignored and copying can be continued.

If there are papers that can serve as mount paper in the paper feed trays 1-'3, the smallest paper among them is fed as a slip sheet and the normal copying routine continues.

FIG. 8 shows another embodiment of the RAM 38 in FIG.
M38 is a battery-backupable RAM such as C-MO8RAM. A diode 47 connects the battery 48 and the normal control power supply Vcc, and supplies the voltage and current of the battery 48 to the RAM 38 when Vee is below a certain voltage. 49 is a resistor that pulls up the RAMC 8 to Vcc and applies voltage from the battery 48 when Vcc drops to maintain data retention state. C- with
If MO8RAM is used, even if the power to the copying machine main body 1 is turned off, the copy size remaining in the paper discharge tray 46 and the sorting turbine can be stored.

(Effects) The present invention is as described above, and according to the present invention, the next copy mode is the sorter 10 pressure plate mode or the sorter 15 plate mode.
Since the automatic interleaving sheet insertion mode is ignored in the ADF mode, it is possible to prevent the same operator from unnecessary insertion of mounts due to forgetting to turn off the automatic interleaving sheet insertion mode during copying work.
