Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is a method for repeatedly setting a copy mode stored in advance in a memory by operating a recall key, and then executing a copy process in this mode. The present invention relates to a copying machine with a recall function.

[Conventional technology]

Copying machines have become more sophisticated, and for example, the number of copies they can make has increased.

Processing conditions such as magnification, density, paper feed size, double-sided/single-sided copy, sort/stack, and binding margin can be selected according to the user's needs. As a result, the number of operation switches to be selected has increased, and the combination of the above-mentioned processing conditions, that is, the setting of the mode of the copying machine has become complicated.

For this reason, several frequently used copy modes are registered in advance in memory and can be easily called up using a recall key when necessary (for example, Japanese Utility Model Publication No. 60168146). This makes the operation for setting the copy mode faster and easier.

[Problem to be solved by the invention]

When a relatively short time has elapsed since copying in a mode that is not registered in memory, there are times when you want to perform additional copying in the same mode again. In this case, if a predetermined time has elapsed since the previous copy was completed, the auto-reset function changes the previous setting mode to the initial setting mode (standard mode). Furthermore, the setting mode may have been changed by another user even before the auto-reset function is activated. Therefore, it is necessary to reset the mode that the user previously used, which is troublesome.

SUMMARY OF THE INVENTION An object of the present invention is to enable a user to immediately set a mode that has been used once when the user wants to use the mode again after only a relatively short period of time has elapsed.

[Means to solve the problem]

The copying apparatus with a recall function of the present invention includes a start instruction means (KS) for instructing the start of copying: the start instruction means (
The copying means (2 to 2) execute the image forming process in the set copy mode in response to an instruction to start copying from the copying means (KS).
9, 11, 12.30) ; The start instruction means (KS
) mode writing means (210) for writing the set mode into the storage means (230) in response to the instruction of
; Condition input means (310) for inputting processing conditions that define the copy mode; Ricol input means (310) for instructing memory readout;
R1): Then, the copy mode corresponding to the input of the condition input means (310) is set, and the recall input means (R1)
mode setting means (210) for reading out the mode of the storage means (230) and setting the copying mode thereto in response to the instruction from the storage means (230);

[Effect]

According to this, the mode writing means (210) writes the set mode into the storage means (230) in response to a start instruction from the start instruction means (KS), and the mode setting means (210) The copy mode corresponding to the input of the input means (310) is set, and the recall input means (R
In response to the memory reading instruction of 1), the mode of the storage means (230) is read and the copy mode is set to this. Therefore, until the start of the next copy, the copy mode used in the previous copy can be stored and immediately recalled to reproduce the copy mode.

In a preferred embodiment of the present invention, the mode writing means (210) erases the oldest storage mode of the storage means (230) in response to a start instruction from the start instruction means (KS).

Therefore, since the copy mode of the currently completed copy is stored until a predetermined number of copies (10 times) have been made after copying, it is possible to store the copy mode for a certain amount of time.

Furthermore, in a preferred embodiment of the present invention, the mode setting means (210) sequentially updates the latest memory every time the recall input means (R1) inputs a memory read instruction until the start instruction means (KS) inputs a START instruction. When the oldest storage mode is read from the storage mode, the latest storage mode is read again and the copy mode is sequentially set.

Therefore, since the predetermined number of stored copy modes can be reproduced only by the instructions from the recall input means (R1), the stored copy modes can be easily set.

〔Example〕 Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 2 shows one type of copier embodying the invention. This will be explained with reference to FIG. Roughly speaking, this copying machine consists of a copying machine body and a group of optional units such as an ADF (automatic document feeder 60, sorter 70, automatic trial duplex unit 80, etc.). The paper system 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 machine, and the third paper feeding system is the second feeding unit 170 and the fourth paper feeding system. A third paper feeding unit 180 including a first paper feeding system and a fifth paper feeding system is connected to the main body of the copying machine.21, 22, 23 and 24 are the first paper feeding system, the second paper feeding system, and the third paper feeding system, respectively. 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 machine, and 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. Third mirror 33° Fourth mirror 34. lens 3
5. A fifth mirror is provided with a 36° slit 37, etc. When performing document reading scanning, a first carriage carrying an exposure lamp 31 and a first mirror 32 and a second carriage carrying a third mirror 33 and a fourth mirror 34 are arranged in two positions so that the optical path length does not change. It is mechanically scan-driven at a relative speed of l. The lens 35 is a zoom lens, and its magnification can be changed by driving a motor.

Therefore, the light emitted from the exposure lamp 31 is transmitted to the first mirror 32.
．． Third mirror 33. Fourth mirror 34. Lens 35. Fifth
Through the mirror 36 and the slit 37, the photosensitive drum 2
imaged on top.

Around the photosensitive drum 2, there are a main charger 3, an eraser 4. Developing device5. Pre-transfer static elimination lamp 6. Transfer charger 7, separation charger 8. Equipped with cleaning unit 9 etc.

The image reproduction process will be briefly explained. The surface of the photosensitive drum 2 is uniformly charged to a predetermined high potential by the discharge of the main charger 3. The charge in the portion not used for image reproduction is erased by the eraser 4. When the charged surface of the photoreceptor drum 2 is irradiated with reflected light from a document, the potential of that portion changes (decreases) depending on the intensity of the irradiated light.

The photosensitive drum 2 rotates in the direction shown by the arrow in the figure, and the optical scanning system 30 sequentially scans the document surface in synchronization with the rotation.
The surface of the photoreceptor drum 2 has the density (light reflectance) of the original image.
A potential distribution corresponding to the distribution, that is, an electrostatic latent image is formed.

When the portion on which the electrostatic latent image is formed passes near the developer Js5, the toner in the developer 5 is attracted to the surface of the photoreceptor 2 according to the potential distribution, and the electrostatic latent image is developed. A visible image corresponding to the electrolatent image is formed on the photosensitive drum 2. 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 fed through the registration rollers 27 so as to overlap the surface of the photosensitive drum 2 at a predetermined timing.

Then, the transfer charger 7 transfers the visible image (toner image) on the photoreceptor drum 2 to the recording sheet side, and the separation charger 8 separates the recording sheet to which the visible image has been transferred from the photoreceptor drum 2. The recording sheet separated by 0 is conveyed to a fixing device 12 by a conveying 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.

After fixing, the recording sheet passes through a predetermined paper ejection path, and then
The paper is discharged to the sorter 70 or the automatic duplex unit 80.

In this example, the main body of the copying machine is provided with a separation sensor 51 and a paper discharge sensor 52 in the transport path of the transfer paper in order to detect the occurrence of a jam while the transfer paper is being transported.

．． These are a paper size sensor and a paper presence/absence sensor provided in each paper feeding system.

By the way, in the copying machine of this embodiment, the RAM 230 has areas 1 to 10 in which ten types of copy modes can be stored, as shown in FIG. That is, in each of areas 1 to 10, modes with different combinations of the number of copies, nine magnifications, density, etc. can be stored.

FIG. 1a shows a flowchart of the copying process of the copier shown in FIG.
, initialization is executed and timers, registers, etc. are cleared (2). Next, preparations necessary for the copying process, such as applying a high voltage and heating the heater of the fixing device, are performed (3), and the initial mode of the copying machine is set (4). In this initial mode setting, copy selection conditions such as the number of copies, copy magnification, and copy density are set to predetermined conditions.

Next, the input set on the operation board 310 is read (IR).

When reading input (IR), if there is an instruction to press the recall key R1 on the operation board 310 (7), the value of register N is incremented by 1 (8), and the copier is set to the mode stored in area N. Set (11), if the value of register N exceeds lO, set the value of N to 1 (9.
10) That is, when the recall key R1 is pressed once, the mode of the copying machine is set to the content stored in area 1.

Furthermore, when the recall key R1 is pressed, the mode is set to the inner spring of area 2, and each time the recall key R1 is pressed, the memory is stored in one of the areas from area 1 to 10 corresponding to the same number N pressed. Set the copier mode to the content specified. When the recall key R1 is pressed for the 11th time, the mode is set to the contents of area l again. The 12th time below is area 2
．． The 13th time is region 3, and so on, repeating sequentially from region l to region 10.

When mode setting is performed by selecting a key on the operation board 310 during input reading (IR).

The settings are changed according to the setting instructions (Sl).

The setting of this mode will be described later.

When a start instruction is received during input reading (IR), the value of the register is set to 0 (12), and the contents of the memory are shifted (13), that is, the contents of area 9 shown in FIG. 5 are transferred to area 10. Then, the contents of area 8 are shifted to area 9, the contents of area 7 are shifted to area 8, . . . the contents of area 1 are shifted to area 2. The contents of area 10 are erased by step 29, new input to area 1 becomes possible, and the current setting mode for copying is stored in area 1 (14).

After that, execute the copy operation (15) and repeat the copy operation until the set number of copies are completed.

When the copying of the set number of spindles is completed, the process returns to step IR and reads the input on the operation board (16). Naturally, by reading this input, steps 6 to 10 described above are performed. Setting mode changes can be made in Sl. In addition, if no key operation input is made within the specified time.

It has an auto-reset function that returns to step 4 and sets the initial mode again (6).

FIG. 1b shows the contents of the mode setting S1 shown in FIG. 1a. In this mode setting S1, the number of copies is set (20).
, copy magnification selection (21), copy density selection (22),
Paper feed port selection (23), duplex mode selection (24), sorter selection (25), and binding margin value setting (26) are sequentially executed. The above settings or selections are all performed on the operation board 31.
If there is no key operation above 0, the setting or selection corresponding to that operation is performed, and if there is no key operation, the current setting or selection remains (no change) and the process proceeds to the next setting or selection.

As described above, in this embodiment, the current copy mode is stored for each copy, and a maximum of 10 types of copy modes are stored. Furthermore, the stored mode can be easily changed by pressing the recall key R1 on the operation board 310. Therefore, when additional copying is performed after a relatively short time has elapsed since copying, even if the auto-reset function is activated or the setting mode has been changed by another user, the mode setting for the previous copy can be made immediately.

〔Effect of the invention〕

As mentioned above, according to the address, the mode writing means (210
) writes the set mode into the storage means (230) in response to the start instruction from the start instruction means (KS), and the mode setting means (210) writes the set mode into the storage means (230).
0), and in response to a memory reading instruction from the recall input means (R1), the copy mode is set corresponding to the input of the memory means (R1).
230) and sets the copy mode to this. Therefore, until the start of the next copy, the copy mode used in the previous copy can be stored and immediately recalled to reproduce the copy mode.

Further, the mode writing means (210) responds to a start instruction from the start instruction means (KS), and the storage means (230)
)'s oldest memory mode. Therefore, the copy mode for the currently completed copy is stored until a predetermined number of copies (10 copies) are made after copying.
It is possible to memorize a certain amount of time.

Further, the mode setting means (210) sequentially reads from the newest storage mode to the oldest storage mode every time a memory read instruction is input from the recall input means (R1) until the start instruction means (KS) inputs a start instruction. , the latest storage mode is read again and the copy mode is sequentially set. Therefore, since the predetermined number of stored copy modes can be reproduced only by the instructions from the recall input means (R1), the stored copy modes can be easily set.
