Abstract

PURPOSE:To simply conform a mode which is set at present by erasing a charge by a charge erasing means with respect to a latent image part which does not confirm with a mechanical operation mode and mechanical information written in a nonvolatile memory, and transferring an unerased latent image to transfer paper as a visible image. CONSTITUTION:By copying a sheet in which all items are described and also all modes are described by some test mode, other mode than the mode which is set at present is erased, only the set mode is transferred onto transfer paper, and the confirmation work is efficiently executed. That is, when an eraser is turned off with a timing against a column of an item, a part of a title of the present set mode, and a part of a character of the mode selected by each item, and other part is lighted, a charge on a drum of an unnecessary image part can be erased, and only a necessary image is obtained as a visible image.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a copy information output device for a copying machine that manages a large number of modes using a nonvolatile memory or the like.

(Prior Art) Conventionally, copying machines have a large number of dip switches (Dip-3
W), and the operation mode of the a-machine was switched by turning on the Dip-SW and turning on the 10FF. For example, there is a buzzer sound, there is no buzzer sound,
This includes whether the copy count is an up count or a down count. However, in recent years, the cost of non-volatile RAM and the like has decreased, and the cost has been further reduced by replacing 0N10 FF' with O/1 of the bits on the non-volatile RAM in terms of hardware.

By the way, with the conventional Dip-3W method 2, you can check what mode is currently set at once, but with non-volatile RΔto4, you can check what mode is currently set. 10 doesn't tell, which means it takes a lot of time to confirm. For example, in test mode 10
By inputting the number corresponding to the desired mode using the keys, symbols and numbers will appear on the display, and by referring to the symbols and numbers in the code correspondence table, you can know the setting mode for the first time. . When checking other items, you have to start inputting the 10 keys again.Also, when checking the machine, check what mode the machine being maintained is set to, and if you use it as a document, the display The code issued by the instrument must be transcribed one time at a time. In particular, the transcribed data must be saved in case of a RAM failure. In this way, in the conventional method, confirmation work, There was a problem that it took a lot of time to store the data.

(Purpose) The present invention was made based on this background,
The object of the present invention is to provide a device that allows each mode to be set on a non-volatile RAM and allows the set modes to be confirmed at once.

(Configuration) For this purpose, the present invention copies a sheet in which all items are described and all modes are described in a certain test mode, erases modes other than the currently set, Transfer only the set mode onto the transfer paper, [1)! This was designed to improve the efficiency of verification work.

The present invention will be explained below with reference to the drawings.

FIG. 1 is a diagram showing an image forming section of a copying machine.

Hara iLi 1 is a contact! - W is placed on the glass 2, and the reference position of the device a is against the original glass 3.

(Print) When the SW is pressed, the optical system turns on the exposure lamp 4 and starts moving rightward by -1. During this time, a charge is applied to the photosensitive drum 5 by the corona charging rf6, but the latent image before the unnecessary placement position is located downstream of the optical path.
Since the eraser 7, which is charge erasing means, is turned on, the charges in the latent image area are erased, and even if the latent image is developed in the developing section 8 located further downstream, it will not become a visible image.

When the original area starts to be exposed, there is a delay corresponding to the delay from the optical path to the erase position, and the eraser 7- is turned off and the charge is not forcibly erased, and the charge corresponding to the original remains on the drum, allowing the latent image to be developed. It becomes a visual image.

Now, in the present invention, a chart as shown in FIG. 2 is used as the transfer paper.

In normal copy mode, the same image as chart paper is naturally obtained. When the copying machine is set to a special mode according to the present invention (hereinafter referred to as check mode), the copying machine executes a check mode routine.

The operation of the copying machine in check mode will be explained.

First, a check sheet (chart), which is an original, is set at the original reference position. When the print switch is turned on, the scanner begins to move as in the normal copy sequence. Edge of chart paper (lead edge) in latent image on drum
After the segment has passed through the eraser, you can selectively turn on each segment of the eraser without forcing the eraser off.
Alternatively, the light is turned off and unnecessary images on the chart are erased as latent images on the drum. 1) is a conveyor belt, 12 is a fixing section, and 13 is a paper discharge tray.

FIG. 3 shows a copy of chart paper obtained by the above process.

By the way, copying machines have many modes that can be selected and changed by service personnel and sales personnel according to the machine's condition, and by users according to their preferences. Each item in the chart shown in FIG. 2 is also part of the selectable modes. For example, item 1, auto clear time, automatically changes various modes of the copier, for example, the magnification to 100, when the machine is left unused for a certain period of time with the power ON.
%, set the number of sheets to 1, set the density adjustment to automatic mode, and also has a function to return to the reference mode.The auto clear time indicates the time to return to the reference mode. In other words, in auto clear 1 minute mode,
Returns to standard mode 1 minute after copying is completed. Like the chart paper of the present invention, you can select this time, and you can select 1 minute, 3 minutes, 5 minutes, and infinite 4fi without auto-clearing.

On the other hand, in recent years, due to the decline in the price of semiconductors, this type of selection has traditionally been made using hardware or IP-3W, but a method of writing the mode state into non-volatile memory has been adopted. That's right. The writing method uses the 10 keys on the operation panel to set the number of copies.

For example, if the auto clear time is set to 1 minute as in the previous example, enter 1> using the IO key. With this input,
Data 01H is written within 1 byte of nonvolatile memory. Also, if it is 3 minutes, data is 02H, if it is 5 minutes, data is 0.
If 3H1 is infinity, it will be written as data 04)1.

The same applies to the registration adjustment data for adjusting the deviation between the image position in item 2 of the chart paper and the transfer paper position in Figure 2, as well as 0 item 3 and below, which are written as data OIH to 05)T in 1 byte of the non-volatile memory. .

Next, a method will be described in which the eraser 7 is selectively turned on and off depending on the contents of the non-volatile memory, and only unnecessary images on the chart paper are filled out to create a solid black image.

Figure 3 shows item 1 for 5 minutes, item 2 for Ofl, and item 3 for 2 minutes.
1) 1. This shows how the erase light turns on and off when item 4 is normal, item 5 is 180° C., and item 6 is up count. Incidentally, for ease of comparison with FIG. 2, the drawing is shown in a two-dimensional manner with the time axis as the paper feeding direction. As shown in Figure 3, the eraser is turned off at the appropriate timing for the item column, the title of the current setting mode, and the text of the mode selected for each item, and the other parts are turned on. By doing so, it is possible to erase the charge on the drum in unnecessary image parts, and only the necessary image can be made visible. In FIG. 3, the eraser 7 in the shaded area is described as being turned off.

Now, we will explain how to create such an erase pattern.

The control program of the copying machine contains data as erase patterns corresponding to the mode of the item (up to 5 modes in this example). The appearance of this data is shown in FIG.

The erase pattern data in the program has seven types of data from 1 to 7. These seven types of data are combined as erase line data according to the contents of the nonvolatile memory mentioned above.

FIG. 5 shows the state of erasing when mode 3 is selected for the amount of white spots at the tip of item 3. This data is the erase basic data and pattern 3 in Figure 4.
It is the logical OR of the data. Note that the bit in the erased part is set to 1, and the bit in the lit part is set to O.

As described above, if erase patterns are created one after another according to the contents of the nonvolatile memory in synchronization with the rotation of the photosensitive drum 50 and output, a copy as shown in FIG. 6 is created.

FIG. 7 is a program flow diagram of erase control.

PLSER starts counting after the leading edge of the image passes through the eraser, and is added to each drum clock pulse that occurs as the drum rotates.This counter determines which part of the latent image is located. It can be seen that the eraser is now passing through part of the eraser. The flowchart shows a part in which data is read from the nonvolatile memory and erase data is created based on the number of pulses of this counter.

FIG. 8 is an external perspective view of the photosensitive drum 5, charger 6, and eraser 7. As shown in FIG.

(Effects) The present invention is as described above, and by executing the above-described check mode, it is possible to easily confirm the currently set mode. Also, 5i1)! You can leave the setting status of vX! on paper as a record. Machine M
W. Copied information can also be used as a book.

This reduces the time required for machine maintenance by skilled service personnel and sales personnel, and also simplifies confirmation work for users.
