Description

Detailed Description of the Invention [Field of the Invention] The present invention relates to an image processing device such as a copying machine, a facsimile machine, etc., which performs image reading and/or recording/reproduction, and a CR
With regard to image processing devices such as word processors and computers that display texts, graphs, etc. on a display screen such as a T, edit them, and record them as necessary, usage management is particularly conducted for each individual and/or section. The present invention relates to an image processing device.

■Conventional Technology Taking copying machines as an example, the enhancement of the functions of copying machines in recent years has improved the convenience of use and made it easier to use. As a result, copying machines have been placed in various places, and many people have become able to easily make large quantities of copies.

Along with this, the following problems have begun to appear, and it is assumed that these will become even more serious in the future.

(1) For example, in a copying machine, when a predetermined number of copies have been made, the photoreceptor drum, toner bottle, etc. must be replaced, inspected, and adjusted, and copies are easily made in a disorderly manner. This makes it difficult to systematically manage copying machines, resulting in disadvantageous results such as wasted costs and the inability to obtain copies of the required quality at the required time.

(2) There are many copies that administrators consider unnecessary, especially private copies.

(3) Secret texts are likely to be copied and taken out to outside parties.

(4) With word processors, computers, etc., it is easy to take out not only hard copies but also information on magnetic media.

In order to prevent such waste and leakage of confidential information and to accurately grasp the condition and replenishment of the copying machine, use of the copying machine has conventionally been managed using a key counter or a key card.

Copy machine usage management using a key counter is limited to cases where a removable key counter is set in the copy machine key counter insertion slot.

The copying machine becomes ready for use. Further, the total number of copies made for each management cycle of the copying machine (hereinafter referred to as the "copy cumulative value") is fixedly displayed in the display window of the counter. Therefore,
For example, if this key counter is provided for each individual or section that uses a copying machine, use of the copying machine can be managed for each section.

On the other hand, in managing the use of a copying machine using a key card, an external card reader is attached to the copying machine, and a key card (on which a code equal to the specific code stored in the card reader is written) is used. For example, the copying machine is ready for use only when a magnetic card (for example, a magnetic card) is inserted. Further, the copy cumulative value is recorded on the key card. A dedicated card writer is used to create the card and to read and erase the recorded copy cumulative value. Therefore, for example, if a department that manages copying machines is equipped with this card writer, and each person using the copying machine has a key card, it is possible to manage the use of the copying machine on an individual basis.

By using these key counters or key cards, the use of the copier can be properly and individually managed, but the required number of key counters or key cards and cards external to the copier - A reader and/or card writer must be prepared, which increases the cost and creates an economic and labor burden on the user.

■Purpose The first object of the present invention is to enable the use of code input for an image processing device without increasing the hardware configuration and without having to carry tangible objects such as cards. The second purpose is to facilitate management, and the third purpose is to facilitate rational use of the image processing device.

■Structure In order to achieve the above object, the present invention provides an image processing apparatus that includes an operation board that receives instructions from an operator, and an image processing control means that controls each part constituting the image processing apparatus according to input from the operation board; A code holding means for holding one specific code; an input means for inputting a specific code; and, when the code inputted by the input means matches the specific code held in the holding means, inputting the operation board. An image processing control means for starting image processing according to the following shall be provided.

According to this, one image processing device can be used by an operator simply by inputting a specific code without carrying objects such as a key card or a key counter. Input operations include, for example, the numeric keys for entering the number of copies on a copier, the numeric keys for dialing the address on a facsimile, the numeric keys on the input board of a word processor or computer, etc.
Since what is already provided can be shared, the addition of hardware configuration is relatively small. Code retention.

This can be done using an electric circuit using dip switches or a storage means such as a non-volatile memory. In the former case, the specific code is set using a dip switch, but in the latter case, the specific code can also be input using the numeric keypad and set in the memory.

For example, in the case of a copying machine, if you want to make copies possible only when a specific code is entered, and never copy at any other time, an assistant to whom a specific code has not been assigned may only be able to make less important copies for the time being. It becomes impossible to make it work. Similar situations may occur with other image processing devices. For example, it may be necessary to have an assistant create new sentences using a word processor or print them out as appropriate, but not allow assistants to make floppy copies of registered sentences.

Therefore, in a preferred embodiment of the present invention, all of the processing modes that can be set on the operation board can be started on the condition that a specific code is input.1 Only limited processing modes of low importance can be started without inputting a specific code. Enable to start.

According to this, one image processing device can be used more smoothly.

Meanwhile, input a specific code to start image processing.

If the device is left as it is after the intended image processing is completed, it is possible that another person will continue to perform the image processing.

Therefore, in a preferred embodiment of the present invention, specific key operations (
(end input) returns the image processing device to waiting for input of a specific code, and if the specific key operation (end input) is not performed,
The pressure plate that presses the document, the document sensor of the automatic document feeder/discharge device (ADF), or the image processing condition setting keys on the operation board are in a state that suggests the subsequent image processing (for example, the pressure plate is open for more than a predetermined time, there is a document present, or the document is being processed. If there is a condition change input), the process waits for an instruction to start image processing; otherwise, it returns to wait for a specific code input.

According to this, after inputting a specific code, image processing is executed under the conditions set on the operation board, and after the process is completed, a specific key operation (end input) is performed.

Therefore, image processing will not start unless the specific code is input again, and even if there is no specific key operation (end input), if there is no possibility that image processing will be commanded subsequently, the specific code will be automatically input again. Image processing will not start if there is no input, and image processing will start in response to a restart instruction when there is no specific key operation (end input) and there is a possibility that image processing will be commanded subsequently. . This allows rational and smooth use of the image processing device.

Other objects and features of the invention will become apparent from the following description of an embodiment illustrated in one drawing.

FIG. 1 shows an outline of the mechanism of an embodiment of the present invention.

This embodiment is an electrophotographic copying machine.

In Fig. 1, ■ is a contact glass on which a document is placed, and a pressure plate 1a that also serves as an automatic document feed/discharge bag [(ADF)].
The document is brought into close contact with the contact glass 1 by a white belt stretched across the bottom of the contact glass 1. The automatic document feeder/ejector has pressure plate 1
It is equipped with an entrance document sensor that detects whether there is a document at the entrance of a, and an insertion white document sensor that detects whether there is a document on the document insertion table lb.
When the print key is turned on and the entrance document sensor detects a document in the ady (copy ready) state, the white belt is driven to feed the document and position it at the exposure position of the contact glass, and Give a start signal to the control device. In addition, the automatic document feed/discharge bag fi (ADF)
A signal (a prediction sensor to be described later) indicating whether or not there is a document on the insertion base lb is given to the control device of the main body of the copying machine.

An optical scanning system 2 equipped with an exposure lamp and the like is provided below the contact glass 1. In this embodiment, the document is fixed, and the optical scanning system is mechanically driven to scan the document. The image created by the reflected light from the original is transmitted to this optical scanning system 2.
The image is formed on the photosensitive surface of the photosensitive drum 3 via the . In FIG. 1, the photosensitive drum 3 rotates clockwise in synchronization with the scanning of the original by the optical system.

The paper feed system has two stages, with paper feed cassettes 4 or 5.
The recording paper is fed out by the paper feed roller 6° or 7 from the selected one. The fed-out recording paper passes between the registration roller 8 and the tip bending roller 9 and is guided to the photosensitive drum 3 (sheet feeding).

Around the photosensitive drum 3 are a charger 10° and an eraser 11. Developing device 12. Pre-transfer static elimination lamp 13, transfer charger 149 separation charger 15° separation claw 16. A cleaning unit 17, a static elimination lamp 18, etc. are arranged.

Next, a general copy process will be explained. The copy process consists of a start cycle, a copy cycle and an end cycle.

When the print key is pressed by the operator.

Or, when the automatic document feeder gives a start signal (copy start instruction), in the start cycle,
The photosensitive surface of the photosensitive drum 3 is cleaned by the cleaning unit 1.
The grounded conductive brush and cleaning blade provided at 7 perform cleaning and neutralization, and the static elimination lamp 18 further eliminates static electricity. When cleaning and static electricity removal are completed and the start cycle is removed, the copy cycle begins.

Photosensitive drum 3 uniformly charged by charger 10
The photosensitive surface of the document is illuminated with light reflected from the contact glass 1 scanned by the exposure lamp.

Its surface potential changes depending on the intensity of reflected light from the original. As a result, an electrostatic latent image is formed on the photoreceptor drum 3. While passing through the developing device 12, toner adheres to this electrostatic latent image and it becomes visible (hereinafter referred to as a toner image).

The recording paper fed out to the registration roller 8 before the start of exposure is fed toward the photoreceptor drum 3 by the registration roller 8 at a predetermined timing according to the rotation of the photoreceptor drum 3. At this time, the leading edge of the recording paper is slightly bent by the leading edge bending roller 9 to facilitate subsequent separation.

When the recording paper passes directly above the transfer charger 14 to which a predetermined voltage is applied, it comes into contact with the toner image formed on the photosensitive surface of the photosensitive drum 3 (transfer). Thereafter, the recording paper is separated from the photosensitive surface of the photosensitive drum 3 by a separation charger 15 and a separation claw 16 and sent to a conveyor belt 19. The conveyor belt 19 feeds the recording paper to the fixing device 20 .

The fixing device 20 is a roller with a built-in heater, and the toner image is fixed onto the recording paper, and the toner image is ejected to the copy tray 22 via the ejection roller 21.

After repeating this process for the set number of sheets, the photosensitive drum 3 is rotated approximately one more time to perform an end cycle in which the photosensitive surface is cleaned and static electricity is removed. If there is a copy start instruction while executing the end cycle,
Skip the start cycle and execute from the copy cycle.

■Effects of the Invention As described above, according to the present invention, it is possible to input codes by sharing the numeric keys already provided in image processing devices such as copying machines, thereby reducing the hardware configuration. It is possible to use the code input of the image processing device and to manage the use of the code input without increasing the number of times, and it is also possible to use the image processing device within a limited range without having to input the code. Furthermore, it is reasonable to use an image processing device because it predicts the operator's next image processing and sets a standby state waiting for a start instruction.
