Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an image forming apparatus, particularly an image forming apparatus equipped with a display means for displaying information from a data input means on a monitor.

[Prior art]

Information input into general computer, personal computer, and other so-called information processing machines is displayed on the screen of a display device and, if necessary, is displayed as a hard copy, which is permanently visualized information.
Wire dots, ink dots, thermal transfer, type impact, etc. are widely used as hard copy recording methods. However, hard copies made using these methods cannot be printed on the display screen.
Since the monitor image displayed on F is not directly optically copied, but is converted into an electrical signal and applied to the recording device, errors due to noise etc. may be added. Furthermore, it is difficult to meet a request to combine other information already recorded on manuscript paper or the like with that information or with a display image to create a blank image. Furthermore, if a large number of output notebook copies are to be made, a copying device is required.

Focusing on these points, the present applicant has arranged a display means for displaying an image formed by electric signals of a facsimile, which is an image communication device, so that it can be guided to the original exposure position, and We have previously proposed a new electrophotographic image recording device that can selectively record images and images of other documents (Japanese Patent Application No. 52-68635).

The present applicant further expands on the earlier proposal to include various information processing devices (hereinafter referred to as
It is intended to be a multifunctional image forming apparatus that is combined with a data input means (referred to as data input means). Interlocking with these data input means 1 (In addition to the single function of copying documents, it is also possible to create documents by freely inserting tables, diagrams, illustrations, etc.) This is because it also makes it possible to print out and copy as needed, making it possible to adapt to the demands of the era of information diversification.

By the way, in the above proposal, when outputting the image displayed on the monitor on the display means from the image recording device as a tocoby, first the display means is placed on the platen glass in order to guide the monitor image to a copyable position. This situation does not occur even if the image recording device is simply combined with a data input means and commands for the notebook forming operation are given from the data input means. No change 1. However, there is usually a difference in display sensitivity between the monitor image on the display means and the image of another document depending on the distance from the document table glass to the image. Therefore, it is necessary to change the nozzle formation process according to the difference, that is, adjust the focus during image formation, change the amount of light during exposure, etc. Therefore, the monitor display image and the original original image may differ.
There is room for improvement in the operability of image formation, such as the need to input note copy start signals separately.

[Purpose of the invention]

The present invention has been made with attention to the above points, and includes: a data input means; a display means capable of displaying on a monitor according to an information signal from the input means and displacing the display surface to an original exposure position; The displacement detection means of the display means and the image forming means arranged at the document exposure position and for exposing and recording the image on the photoreceptor are integrated as a system, and the image forming means is activated by the signal 3- of the data input means. It is an object of the present invention to provide an image forming apparatus so as to start the image forming preparation process and to start the image forming process in response to a signal from a displacement detecting means.

〔Example〕

1 to 4 show an embodiment of the present invention, in which a copying apparatus 1 serving as an image forming means rotates around a shaft 1a and places an original (not shown) on an original platen glass 1b. A crimping plate Ice is provided to be crimped, and a display means 2 consisting of a liquid crystal display panel is mounted on the crimping surface.

When the crimping plate 1c is not being copied, it is held in the open state as shown in FIG. 1 by a locking device (not shown) so that the screen of the display means 2 can be viewed. 3. In addition to the liquid crystal panel, the display means 2 may include, for example, a plasma display spring/I/? A light emitting diode may also be used. 1d, the display means 2 is placed on the document table glass 1.
b This is a detection switch which is means for detecting that the exposure position has been displaced by tilting it upward.

Reference numeral 3 denotes an arithmetic processing unit with a keyboard as data input means, which is connected to the copying apparatus 1 and the display means 2 via a signal line 4.

FIG. 2 shows the functional configuration of the copying apparatus 1, in which the exposure system 5
, an image forming system 6, a paper feeding/conveying system 7, and a control system 8.

At the time of copying, the display means 2 attached to the pressure bonding plate 1c or the original document to be copied (original document) written on a separate sheet (manuscript paper, etc.) is on the document table glass 1b, and the document illumination section 9
When irradiated by the exposure light source, the reflected light passes through the optical path section 10.
After that, the photoreceptor 11 is exposed to light and a light image is formed. Of course, this exposure light source is not necessarily necessary when the display means 2 is self-luminous (for example, a plasma display).

Various electrophotographic processes can be applied to the copying process and L- of this invention, and in this embodiment, the following processes are applicable. The photoreceptor consists of 11 photoreceptors, a conductive support, a photoconductive layer, and an insulating layer, and after being uniformly charged by 17 parts in advance by primary corona charging in the electrostatic latent image forming section 12, it is subjected to the photoimage exposure ( (Charge removal with secondary corona charging (C) is performed, and the entire surface is uniformly exposed to a full-surface exposure lamp to form an electrostatic latent image according to the light image. This electrostatic latent image is electrostatically developed in an f imager 13 having a developer (toner) mainly composed of predetermined charged colored particles.The developed image is sent from a cassette 14 via a paper feed control section 15. The image is transferred onto the transfer paper using an electric field generated by the transfer charger 16.

The transferred transfer paper is separated from the photoreceptor 11 by the separator 17, and sent to the fixing device 19 by the conveying section 1B. Here, the paper is thermally fixed by the heater H of the fixing device 19 and is discharged onto the tray 20 as a hard copy. On the other hand, photoreceptor 1
The remaining charged particles on the toner 1 are removed by the cleaning section 21 and collected by the toner collecting section 22 . The above process is repeated according to the number of copies to obtain a predetermined number of hard copies.

Note that 23 is a surface potential control section that controls the surface potential on the photoreceptor 11 by controlling the voltages of each corona charger, exposure lamp, and developing device 13 of the electrostatic latent image forming section 12 .

The image forming process by the above-described exposure system 5, image forming system 6, and paper feeding/conveying system 7 is sequentially controlled by a control circuit section 8a of a control system 8 according to a preset program. Further, the number of copies and copy size can also be selected by sending a command signal from the data input means 3 and executing a program stored in the memory.

That is, in response to a copy preparation command to the control circuit section 8a of the control system 8, power supply to a heater controller (not shown) that controls the heater H of the fixing device 19 is started, and the power supply is continued until the fixing roller temperature reaches a predetermined temperature (for example, 150 degrees Celsius). Warm-up occurs.

Next, the photoreceptor 11 begins to rotate at a low speed, and its surface is almost uniformly neutralized by the secondary charger of the electrostatic latent image forming section 12 and the exposure lamp. During the subsequent low-speed rotation, the temperature of the fixing roller of the fixing device 19 is made to reach, for example, 170° C., and the exposure of the photoreceptor 11 is stabilized by irradiation with an exposure lamp.

When the fixing roller temperature W reaches 170 DEG C., the photoreceptors 7-11 start rotating at high speed, and the surface of the photoreceptor 11 is electrostatically cleaned by the exposure process and the operation of each charger. Next, control rotation is started, and the surface potential is corrected to obtain the target surface potential. With the completion of the copy preparation process described above, the setting of the copyable state is completed. From this point on, by sending a copy start signal to the control circuit section 8a, the copying processes described above, such as exposure, latent image formation, development, transfer, and fixing, are immediately started.

3 are diagrams showing the basic structure of a liquid crystal spring υ which is an embodiment of the display means 2 according to the present invention. Electrodes 25 and 2
The electrodes 25 and 26 are made of so-called transparent conductive films such as indium oxide, tin oxide, etc. However, the electrode surface is divided into stripes in advance by etching or the like, and a lead is taken out from each divided electrode. The resolution of the image is determined by the pitch of the divided stripe-shaped electrodes 25, 8-26. Reference numeral 29 designates an X-axis switch circuit that sequentially scans the electrodes 25, and a Y-axis switch circuit that scans the 30-4 electrodes 26, thereby sequentially applying the power supply voltage according to the signal from the data input means 3 to each electrode. . Of course, other liquid crystal driving methods may be used, such as a well-known voltage averaging method. To erase the liquid crystal display, apply a voltage l (
This is done by applying a pulse.

FIG. 4 shows a basic system circuit of the image forming apparatus shown in FIGS. 1 to 3, and the data input means 3 includes a keyboard 31 as an operation means, a CPU 32, a clock generator 33 that sends clock signals to the CPU 32, and a system controller. CPU group 35 consisting of 34, ROM3fi,
It is equipped with a memory 38 consisting of a RAM 37 and an external memory as necessary, and an input/output interface 41 having a l1039.40e, the output of which is input to the display means 2 and the control system 8 of the copying machine 1 described above to control system operation. connected to control. At the same time, the ON signal of the detection switch 1d is designed to serve as a coby-start command to the control system 8.

That is, by operating the keyboard 31, the data input means 2
, an information signal is output to the display means 2 via the signal line 4a according to a program stored in the memory 38 in advance. The display means 2 is driven according to the information signal, and a predetermined display image is formed on the liquid crystal panel surface.

On the other hand, this information signal is simultaneously outputted to the control system 8 of the copying machine 1 through the signal life 4b, and becomes a copy preparation command for the copying machine 1. Then, in the copying machine I, the above-mentioned warm-up of the fuser heater H, the subsequent surface potential control, and the copy preparation process such as focus adjustment and exposure amount adjustment of the exposure system 5 are immediately started. Through the above process, the copying enabled state of the copying machine 1 is set.

Normally, this copy preparation process ends before the formation of the monitor image on the display means 2 is completed.

Therefore, when it is desired to make a hard copy of the image displayed on the display means 2, all that is required is to lower the display means 2 onto the document table glass 1b, and the detection switch 1d is turned on, and the signal is transmitted to the control system 8 of the copying machine 1. As a result, scanning of the display screen by the exposure system 5 is started without waiting for the warm-up rise time, and without having to go back to the data input means 3 and separately output a copy start command. . Continued sub 1
The copy process of image formation, image formation, transfer, and fixation proceeds automatically to obtain a hard copy of the monitor image.

Of course, apart from the monitor image, it is also possible to place a normal original original on the original platen glass 1b and obtain a copy of it.

〔Effect of the invention〕

As explained above, according to the present invention, when the data input means is operated, the image forming means starts warming up, and then the copying process can be immediately executed by simply flipping down the display means. A functional image forming apparatus is obtained.
