Therefore, the usage efficiency of the cut sheet recording device is greatly improved.

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

FIG. 1a shows an exemplary copying apparatus.

Briefly speaking, this copying device consists of a copying device main body, an AD
F (Automatic document feeder) 60. Sorter 70, automatic double-sided processing unit 80. It is composed of a group of optional units such as paper feed units 170 and 180. The paper feed system that supplies recording sheets has five stages. That is, the first paper feeding system and the second paper feeding system are provided in the main body of the copying apparatus, and the third paper feeding system including the second paper feeding unit, the fourth paper feeding system, and the fifth paper feeding system is provided. A paper feed unit is connected to the main body of the copying machine. 21, 22, 23 and 24 are the first paper feeding system, respectively;
These are cassettes provided in the second paper feeding system, the third paper feeding system, and the fourth paper feeding system, and 25 is a tray of the fifth paper feeding system.

A contact glass 1 on which a document is placed is provided at the top of the main body of the copying apparatus. An optical scanning system 30 is provided below the contact glass 1.

The optical scanning system 30 includes an exposure lamp 31. first mirror 32,
Second mirror 33. Third mirror 34. lens 35, fourth mirror 36. It is composed of slits 37 and the like.

When reading and scanning a document, a first carriage equipped with an exposure lamp 31 and a first mirror 32 and a second mirror 3
3 and a second carriage carrying the third mirror 34,
It is mechanically scan driven at a relative speed ratio of 2:1 and the optical path length is kept constant. The moving direction of the first and second carriages, that is, the sub-scanning direction is the left-right direction in FIG. 1a, and the sub-scanning starting position is at the left end. At the sub-scanning start position, a home position sensor (not shown) detects the second carriage and is turned on. Further, a reference density pattern 13 is arranged at the image reading position at the start of sub-scanning.

This reference density pattern] 3 is used to compare the density of the corresponding development and the reference density to adjust the developer density.

The lens 35 is a zoom lens, and is driven by a motor to change the copy magnification.

The light emitted from the exposure lamp 31 is reflected on the surface of the document and
Mirror 32. Second mirror 33. Third mirror 34, lens 35. An image is formed on the photosensitive drum 2 via the fourth mirror 36 and the slit 37.

Around the photoreceptor drum 2, there are a main charger 3 and an eraser 4. Developing cartridge 5. Toner image sensor (hereinafter referred to as P
(referred to as a sensor) 6. Transfer charger 7° Separation charger 8. A ticking unit 9 and the like are arranged.

Briefly explain the copy process.

The photosensitive drum 2 rotates in the direction shown by the arrow in the figure, and when it passes directly under the main charger 3, its surface is uniformly charged to a predetermined high potential by the discharge, and the eraser 4
When passing directly under the , the charge in the part not used for copying is erased. When the charged surface of the photosensitive drum 2 is irradiated with reflected light from the original, the potential of that portion changes (exposure neutralization) depending on the intensity of the irradiated light.

Since the optical scanning system 30 sequentially scans the document surface in synchronization with the peripheral speed of the photoconductor drum 2, the surface of the photoconductor drum 2 has a potential distribution corresponding to the density (light reflectance) distribution of the document image. ,
That is, an electrostatic latent image is formed.

When the part on which the electrostatic latent image is formed passes near the developer cartridge 5, the toner in the developer cartridge 5 is electrostatically attracted to the surface of the photoreceptor 2 according to the potential distribution, and the toner is absorbed in the vicinity of the developer cartridge 5 according to the electrostatic latent image. A visual image is formed on the photoreceptor drum 2 (development).

On the other hand, in synchronization with the progress of the copying process, recording sheets are supplied from one of the five paper feeding systems selected. This recording sheet is passed through the lens l-roller 27.
The visible image (toner image) on the photosensitive drum 2 is transferred by the transfer charger 7 at a predetermined timing so as to overlap the surface of the photosensitive drum 2, and the visible image is further transferred by the separation charger 8. The separated recording sheet is separated from the photoreceptor drum 2.
The image is transported to a fixing device 12 by a transport belt 11 .

After passing through the fixing device 12, the toner image on the recording sheet is fixed onto the recording sheet by heat within the fixing device 12. The recording sheet that has been fixed is discharged to the sorter 70 or the automatic duplex unit 80 through a predetermined paper discharge path.

When the paper is discharged to the sorter 70, the discharge sensor 14 detects the discharge.

The paper size sensor 230 is connected to the paper feed cassette 21°22.2
This is an optical sensor for reading the size of the recording sheet set in 3 and 24 and the paper feed tray 25.

See Figures 1b and 1c. FIG. 1b is a perspective view showing a part of the paper feed tray 25.
In this case, the recording sheets are stacked on the mounting table 25a, and the sides are pressed down by the side guides 25b. Referring to FIG. 1C, the side guide 25b includes two guide rails 25c.

It is supported by a bracket 25e that slides on the bracket 25d, and is configured to freely move in the direction of the guide rail.

Note that the paper size sensor 230 includes each paper feed cassette 21.
, 22, 23, 24 and a sensor for detecting the presence or absence of recording paper in the paper feed tray 25.

The RAM 240 has a nonvolatile memory area, in which the total number of copies is written in correspondence with the size of the recording sheet.

The backup unit 290 includes a battery BT, and when the supply of constant voltage Vcc from the power supply unit 210 is cut off (commercial power supply is cut off), a predetermined voltage is supplied to the RAM 240 to store data in the nonvolatile memory area. Protect your content.

Next, FIG. 8, FIG. 9, FIG. 10, and FIG. 11.

The operation of the CPU 200 will be specifically described with reference mainly to the flowcharts shown in FIGS. 12, 13, and 14.

The flowchart shown in FIG. 8 shows the general routine of the CPU 200. Referring to this, when the power is turned on, the CPU 200 first performs initialization mode processing (I
After performing the L mode processing), the standby mode processing (wait mode processing = WT mode processing) is performed in a loop until the copying is possible and the print start key KS is operated, and starts when the print key KS is operated. Perform mode processing (ST mode processing), copy mode processing for one copy (CP mode processing), finally perform end mode processing (ED mode processing), and return to standby mode processing (WT mode processing). Repeat the above. During this time, if an abnormality is detected, predetermined abnormality processing is executed.

In the IL mode processing, the areas outside the nonvolatile area of the RAM 230 are initialized, each component is initialized, and the like.

In WT mode processing, the operation of each key switch on the operation board is read and processing corresponding to the operation is set. In Figures 9, 10, 11 and 12,
A part of the subroutine executed in WT mode processing is shown.

See FIG. 9.

This subroutine w'rotoo consists of a recording sheet size register A (m) and a recording sheet presence/absence register B (m
) is a subroutine that sets the

First, the value of m is set to 1, and the code of the recording sheet size held by the cassette (21 in FIG. 1a) installed in the first sheet feeding system is stored in register A(1).

In this example, A3 size is code II I H
Code “2” for 2B4 size, code “3” for A4 size
", B5 size is code "4", AS size is code "5", and B6 size is code 116 II.

For other sizes or when no paper feed cassette is installed, tr 7 u is stored in register A(m).

Next, it is checked whether there is a recording sheet in the cassette, and if there is a recording sheet, rr i 1' is entered in register B (1).
, and when there is no recording sheet, LL O11 is stored.

Thereafter, the value of m is incremented by 1, and the above process is performed for all five stages of paper feeding systems.

Please refer to FIG.

This subroutine WTO200 is a subroutine that detects information regarding the paper feeding system that is being set.

If the size of the recording sheet held in the cassette or tray attached to the paper feed system being set is A3 size, store 111H in register C, and if it is B4 size, store '2'' in register C, For A4 size, store 113'1 in register C, for B5 size, store "4" in register C, and for A5 size, store 113 '1 in register C.
When the size is B6, 1161+ is stored in register C. When none of the sizes corresponds to the above, for example, when no paper cassette is installed, or when a universal cassette containing irregularly sized recording sheets is installed, register C
Store ``0'' in .

Please refer to FIG.

This subroutine WTO300 includes key switch K1
．． This is a subroutine for setting the paper feeding system in the standard mode that is activated at the start of the operation No. 3, that is, when a mode clear instruction is input.

When the start of operation of 13 is detected on the key switch.

The size code stored in memory 5(1) is stored in register D. I will add an explanation to this.

As shown in FIG. 4, the nonvolatile memory area of the RAM 240 includes a memory area 5(n) that stores a size code indicating the recording sheet size, and a memory area that stores the total number of copies corresponding to the code. Q(n) are provided (n=1 to 6), and size data and data of the corresponding total number of copies are written in descending order of the total number of copies. In other words, the size data of the recording sheet with the largest total number is written in 5(1), the total number of sheets is written in Q(1), the size data of the recording sheet with the next largest number is written in 5(2), and the total number of sheets is written in Q(1). 2)
It is written like this.

- Please refer to FIG. 7 for an example.

Referring again to FIG. 11, the data stored in the memory 5(1) stored in the register D is the size data of the recording sheet that is copied the most, that is, the size data of the most frequently used recording sheet. . For example, in FIG. 7, 5(1)=5, that is, the value 1151 indicates the A5 size with the largest total number of copies (530 copies).
Store 1.

In the next loop, change the value of m from 1 to 5, check the value of the size register A (m) mentioned above, and check the value of the size register A (m) that matches the value of register D.
When detected, the m-th sheet feeding system is set based on the value of m at that time. For example, in the above example, when 5 is stored in register D and a cassette containing A5 size recording sheet l- is set in the third paper feed system, register A (3 )
Since 5 is stored in , when m = 3, A(m) =
It becomes D.

In this case, set the third paper feed system.

If there is no size register A (m) that stores a value that matches the value of register D, then in the next loop m
Change the value of 1 to 5 and record sheet presence/absence register B
(m), first there is a recording sheet (that is, 111
II) Search for the value of m that detects. For example, if there is no recording sheet in the cassette installed in the first paper feeding system and there is a recording sheet in the cassette installed in the second paper feeding system,
When the value of m is 2, B(m)=1, so the second paper feeding system is set.

When O is stored in all registers B(1) to B(5), that is, all cassettes or trays installed in the first to fifth paper feed systems have no recording sheets, or all cassettes or trays are empty. If it is not installed, set m=L and set the first paper feeding system.

Please refer to FIG.

This subroutine WTO400 is a subroutine for setting the paper feeding system for the 4m semi-mode when the copying machine is not in use, and clears the Ta timer (internal timer) when there is an operation input from the key switch on the operation board 300. & starts and returns to the WT mode processing routine, and when there is no more input, the value of the Ta timer is monitored. Also, C
Since the PU200 also clears and starts this Ta timer when ending the ED mode processing, the value of the Ta timer is changed after the last key switch operation is performed or after the last copy is created. It indicates the time of .

When the Ta timer times out (about 1 minute in this embodiment), the standard mode paper feeding system is set.

The processing of the part surrounded by the two-dot chain line in Fig. 12 is the first
Since the processing is the same as the processing of the part surrounded by the two-dot chain line in Fig. 1, the explanation will be omitted.

Referring again to FIG.

In ST mode processing, the main motor is warmed up as a step before executing the copying process described above.
The photosensitive drum 2 is cleaned before copying, etc. In addition, in the CP mode processing, processing related to the copying process described above, that is, charging, erasing, exposure,
Processes such as development, transfer, and fixing are performed.

The flowchart shown in FIG. 13 shows a subroutine for detecting the discharge of a recording sheet and counting up the total number of copies.

In this case, when paper discharge is detected, the value of n is changed from 1 to 6, the memory 5(n) is searched for size data that matches the size data stored in register C, and the matching data is searched. When detected, the data for the total number of copies stored in the memory Q(n) is counted up by one based on the value of n at that time.

The processing mode at this time will be explained with reference to FIG.

When the recording sheet size being set is A3 size, 1 is stored in register C in the aforementioned subroutine WTO200, so when the value of n is updated sequentially from 1 and the write data of 5(n) is examined, rl- When 4, 5 (4)
=1. Therefore, the write data in memory Q(4) is counted up by one.

After repeating the CP mode processing for one designated number of copies and completing the processing, post-copy cleaning processing of the photosensitive drum 2 is performed in the ED mode processing.

When a series of copying processes is executed, the total number of copies changes, so the arrangement order of the memories 5(n) and Q(n) may differ in the order of the total number of copies.

Therefore, in this ED mode processing, a subroutine ED0100 for rearranging the memories 5(n) and Q(n) shown in FIG. 14 is executed.

The subroutine EDO100 will be explained using the data shown in FIGS. 6 and 7 as an example.

FIG. 6 shows the total number of copies that has changed due to execution of a series of copying processes (in reality, such a large change is rare).

First, set the value of n to 1, set n to register E, and register F.
In other words, store n+1 in E=1. F=2), memory Q
The value of (E) and the value of memory Q(F) are compared. Q(E
), the value of register F is stored in register E. In this case, from Q(1) to Q(2
) is thicker, so 2 is stored in register E.

Next, register F is incremented by 1 (3) to obtain the value of memory Q(E) and the value of memory Q(F), ie.

The value of Q(2) and the value of Q(3) are compared. in this case,
Since Q(2) is thicker than Q(3), without updating the value of register E, register F is incremented by 1 to 1 and the above is repeated.

Until the value of register F reaches 6, the value of register E is not updated because the value of (2) in the memory is larger than any of the values.

It can be seen that in this loop, the value of memory Q(6) is maximum. Therefore, 6 is stored in register E.

Therefore, when this loop ends, the memory Q (n)
write data and memory Q(E) write data, memory S(n) write data and memory 5(E) write data, in this case, memory Q(1) write data and memory Q(6) write data, memory The data written in 5(1) and the data written in memory 5(6) are exchanged, and the maximum total number of copies and the corresponding size data are transferred to the n=1 column.

If you increment the value of n by 1 and execute the above process, the second highest total number of copies will be detected, so
The number of copies and the corresponding size data are n.
Write to each memory of =1.

Repeating this until n=6 is the seventh
This is the data shown in the figure.

As shown in FIG. 7, the data arranged in descending order of the total number of copies is then
Alternatively, it is used when setting the standard mode paper feeding system in WTO400.

In the above embodiment, the total number of copies per copy is organized in association with the size data of the recording sheet, and the priority order of the paper feed system is set based on this, but instead of the size data, for example, Data indicating the paper tray may also be used.

In addition, in the standard mode paper feed system settings (subroutines WTO300 and WTO400) of the above embodiment, if the recording sheet corresponding to the size data of the most frequently used number is not prepared, the first to fifth paper feed systems are The paper feed system with recording sheet is set first, but if the recording sheet corresponding to the size data of the most frequently used number is not prepared, the next recording sheet corresponding to the size data of the most frequently used number is set. For example, if the corresponding recording sheet is not prepared, the paper supply system may be set to sequentially supply recording sheets that are used less frequently.

■As described in detail about the invention, according to the present invention, the number of records is stored in association with the supply information of the cut sheet supply means, and when recording ends, the cut sheet obtains the supply information that has the largest number of stored records. Since the sheet feeding means is automatically selected and set, the usage efficiency of the cut sheet recording apparatus is greatly increased.
