Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention (Field of Industrial Application) The present invention generally relates to an electrophotographic copying machine,
In particular, it relates to an attached electrophotographic copying machine for editing information data.

<Prior Art> In general, electrophotographic copying □ makes copies one after another from an original.a Recent copying machines can not only reproduce copies identical to the original, but also make copies modified from the original. Therefore, copying machines erase unnecessary data from a document and add new data. In this manner, the copier performs an information data editing function, thereby reducing the effort and time required to make revised copies from hand-held manuscripts. In electrophotographic reproduction machines, a latent image is recorded on a photoconductive surface and developed to transfer the powder image to a copy sheet. The powder image is then fused to the copy sheet. A latent image of a document is formed by scanning the document, projecting an optical image onto a charged portion of a photoconductive surface, and selectively discharging the charge. The latent image is edited by superimposing an electrically modulated beam, such as a modulated laser beam. The modulated laser beam adds additional information or removes information from the latent image.

In this way, a modified copy is obtained from the original. Various techniques have been devised for sending electrical signals that modulate the radar so that the desired information is recorded in the latent image.

For example, the Banasonic E2Sm copy machine uses an electronic pad to edit, move, and delete information on the copy, and the Panasonic electronic print board uses a copying trowel to automatically copy information recorded on a blackboard-sized electronic blackboard. You can copy it onto the sheet. In order to define the area to be modified, the coordinates of the document to be modified must be sent to the copier. NP3, which is also manufactured by Canon■
The 525 copier employs an editing pad that allows you to add color to highlight or erase selected portions of the copy. A digitizer can also be employed to determine the coordinates of the document to be modified. For example, U.S. Patent No. 4.088
．． No. 842, No. 3.904.822, No. 4.080゜515, No. 4.243.843@, No. 4,368.3
An example of a digitizer is disclosed in No. 51, No. 4.368.352. That is, it is also possible to use a digitizer to determine the coordinates of the document to be modified and to insert additional information into the copy. Various techniques have been devised for modifying copies of manuscripts. Please refer to the following.

(Examples) The present invention will be described below along with preferred examples, but the present invention is not intended to be limited to the examples. On the contrary, the intention is to cover all alternatives, modifications, and equivalents falling within the spirit and scope of the invention as claimed.

For a general understanding of the nature of the invention, reference is made to the drawings. In the drawings, like elements have the same reference numbers. FIG. 1 shows an electrophotographic copier that makes copies and an editing pad that changes the copies without changing the original. As will become clear in the following description, the editing pad of the present invention is widely suited for use in copiers and other devices when it is desired to change a copy without changing the original. The features of the invention do not apply only to the particular embodiments described herein.

The copying method and its operation will be explained with reference to FIG. Since the technology of electrophotographic copying machines is well known, the operation of the copying machine will only be briefly explained.

The electrophotographic copying machine 1o can make a series of copies with information on only one side of the paper or on both sides. A circulating original feed basin 12 is provided on a platen (not shown) in the image section of the copying machine 10. The document feeder 12 is configured to sequentially feed documents to a platen for copying. The document feeder 12 normally operates in a collation mode, in which documents are fed one at a time from a stack in a tray above the feeder, one at a time, to be copied, and then returned to the stack. The manuscript is placed on the feeder in a predetermined page order. For example, the first page is placed at the top of the stack, the last page is placed at the bottom of the stack, and the last document is sent to the platen first and then returned to the top of the stack.

The operator can use the operation control panel 14 and the editing band 16 to control the movement of each copy and its associated equipment.

If desired, the recirculating document feed gun can be pivoted upward to allow the operator to manually place the document onto the platen of the copier. In this operating mode, the circular document feeding mode does not operate. The editing band 16 connects the R8232C connector 18 to the adapter 20 of the control panel 14 of the copier 10.
By searching, it is connected to the copying machine 10. If the editing pad is placed away from the copier 10,
The copy change data is stored in the portable memory key 22. This key is first inserted into the edit pad 22 to store the required change data and then inserted into the receptacle 24 of the control panel 14 of the copier 1110 to turn the copier υIt[IL, and make the required copies. Changes can now be made.

Generally, electrophotographic reproduction lines include a belt with a photoconductive surface formed on a conductive substrate. The photoconductive surface of the belt passes through various processing stations located along its path of travel. First part of the belt passes through a charging section. In the charging station, a corona generator charges the photoconductive surface of the belt to a relatively high voltage and substantially uniform potential. After that, Hikari I! The charged part of the surface advances to the image section.

In the iti section, the scanning lamp, lens, and mirror move while intermittently irradiating the document one part at a time.

Light rays reflected from the original document are transmitted through the lens to form a light image. These light beams are imaged onto the charged portions of the photoconductive surface and selectively quench the charge thereon. This records an electrostatic latent image on the photoconductive surface corresponding to the information contained in the document placed on the platen. If one wishes to selectively erase part of the original or add other information, the writing device is activated. As the writing device, an image forming device using one of a laser, an ED, and an LCD can be employed. When using a laser device, the laser beam is modulated to selectively illuminate charged portions of the photoconductive surface to add information to or subtract information from the copy. If it is desired to move the information on the document, the lens is automatically moved from the starting position coordinates to the new desired position @coordinates as the optical system scans the document. In this way, the information of the original can be transferred to new coordinates on the copy paper. After the electrostatic latent image is recorded on the photoconductive surface, the belt advances to a development station. In the development station, a magnetic brush developer brings a developer mixture of carrier particles and toner particles into contact with the electrostatic latent image recorded on the photoconductive surface. The toner particles are attracted from the carrier particles to the electrostatic latent image to form a toner powder image on the photoconductive surface of the belt. At least 2 developing systems
Contains 91 current numbers. One of them has toner particles of black color, and the other machine contains toner particles of another color.

By doing this, it is possible to obtain a copy in a desired color other than the black area, or to make a part of the copy stand out in another color. In either case, toner particles are attracted from the carrier particles to the electrostatic latent image to form a toner powder image on the photoconductive surface. After development, the belt transports the toner powder image to a transfer station. At the transfer station, the copy sheet is advanced into contact with the toner powder image. A corona generator sprinkles ions onto the back of the copy sheet.

This draws the toner powder image from the photoconductive surface to the copy sheet. After transfer, the copy sheet advances to a fusing station. At the fusing station, fusing pads permanently affix the transferred toner powder image to the copy sheet. The fixing device includes, for example, a heating roll and a backup roll. The copy sheet passes between a heated roll and a backup roll, and the toner powder image contacts the heated roll. In this manner, the toner powder image is permanently fixed to the copy sheet. After fusing, a transport belt guides the copy sheet to a catch tray, and then an operator removes the copy from the copier.

Alternatively, the copy sheets may be directed to a finishing station where multiple copies may be stapled or bundled to form multiple sets.

The editing pad 16 is adapted to control changes made to the copy sheet. If the editing pad is located remotely from the copier, the changed information is stored in memory key 22. Alternatively, if the edit pad is connected to the copier by connector 18, an R3232 connector, the change information can be sent directly to the copy shop so that an immediately enhanced copy can be obtained. As a general explanation of a copying machine that includes this sounding, the above explanation is considered to be sufficient for the purpose.

FIG. 2 shows the detailed structure of the editing pad.

The editing pad 16 includes a digitizing section 26, a menu selection section 28 adjacent thereto, and a keyboard section 30. The coordinates of the document are confirmed by placing the document in the digitizing section and touching the document to be changed with the positioning stylus 32.

In this way, the position coordinate information is transferred to R8232 channel 1.
8 directly to the copying machine or to the memory key 22. In either case a suitable digitizer is used. For suitable digitizers see, for example, US Pat. The menu selection section 28 includes a plurality of g collections and job programming functions,
These are activated by contacting the stylus 32 with a selected block.

Insert the stylus 3 into the block selected in the menu selection section 28.
2 determines what should be done to the selected portion of the document. Alternatively, by selecting an appropriate block in the menu selection section and selecting keys on the keyboard section 30 with the stylus 32, desired information can be input and other text added to the document. Instead of the stylus 32 actuated keyboard part, a conventional type-type keyboard may be used.

Information to be added to the copy of the original is displayed on the display 34. This display is a 40-character, two-line liquid crystal display (LCD) used solely for the purpose of displaying input data to be added to the original copy. The LCD display is also programmed to provide sequential instructions for using the wA collection pad. Another suitable display is a radiographic tube (CRT). Memory key 22
is an erasable and programmable read-only memory. For example, a 16 kilobit chip may be used to store information used to program the operation of a remotely located copying machine.

The detailed structure of the overlay menu portion 28 is shown in FIG. Each block defines a particular operation to be performed on the copy. Each block is located at a separate coordinate on the digitizing section. In this way, when touching a particular block with the stylus 32, the logic it, I
Specific position coordinates are established for operating the It211 device to perform specific tasks within the copier. For example, if you want to erase selected information from a copy sheet, use the stylus to
touch the erase block. The digitizer sends a signal indicating the position coordinates of the erasure. The information desired to be erased is selected and its position coordinates are confirmed by the digitizer. The digitization unit sends a signal indicating the position coordinates of the information to be erased from the copy and an operation to be performed on the copy, that is, to erase the information. The erase signal modulates a light emitting diode array (LED) or laser beam to erase selected portions of the document from the copy sheet. This is accomplished by irradiating selected portions of the electrostatic latent image after the latent image of the document has been recorded on the optical i#electronic screen. In this way, the desired information is erased. If you wish to move the selected portion of the text you are copying, place the stylus over the move block in the overlay menu 28. Then, during the scanning operation of the original, the lens is moved to a new position coordinate and a signal J is generated, which is sent to the control circuit. In this manner, the optical image of the selected portion of the document is moved to move the selected portion of the electrostatic latent image recorded on the photoconductive surface. In this way, the selected information on the original is moved to new position coordinates on the copy. The frame position of the necessary information is determined by the movement of the lens. Along the direction of processing,
The position of the latent image is delayed with respect to the position of the covey sheet.

By selecting various blocks in the overlay menu 28, signals of the position coordinates of the corresponding digitizer are sent, and the signals cause the respective operations in the copier to make the desired changes on the copy sheet. Added.

FIG. 4 shows a block diagram of the electronic circuitry employed. An Intel 8051/8031 microcontroller chip 36 provides basic control.

The microcontroller chip 36 is connected to the digitizing section 26
Receive information from. This information is sent to multiplexer 38,
Analog circuit 40. It is sent via an analog-to-digital converter 42 and a latching circuit 44. The output of the analog-to-digital converter is also sent to random access memory chip 46. The software that decodes the coordinates and operates the digitizer is stored in read-only memory chip 48. The output of digitizer 26 is also connected to display 34. Microcontroller 36 controls a drive circuit 50 connected to stylus 32. Memory key 22 is housed in septacle 52, and the receptacle is connected to display 34 and microcontroller 36 via buffer 54. A power plug 56 connects the control N source 58 to an external power source. The microcontroller 36 obtains the position data from the digital section, arranges the data in a transmission format, and stores the data in the memory key 22 or the R8232.
Send data to copy 8110 via channel 18.

The microcontroller has a data bus line and several peripheral circuits, namely a display 34, an analog-to-digital converter 42, and a non-volatile memory key receptacle 52.
, programmable read-only memory 48, and random access memory 46. Analog-to-digital converter 42 is connected to analog circuitry 4o that supports digitizer 26 and provides raw digital position information to microcontroller 36. Key receptacle 52 is a physical socket for nonvolatile memory key 22 and electrically connects the memory key to the controller's pass line.

Buffer 54 between the data bus line and the key receptacle is not needed if the key is removed and the edit pad is inactive. However, if the editing pad operates with or without keys, a line buffer is required, so buffer 54 is required. External application read only memory 48 and random access memory 46 each preferably have 4 kilobits of memory.

As shown in FIG. 6, interface logic 60 is also connected to digitizer 26 and microcontroller 36. It is also connected to the memory key 22, R3232 connector 18, and liquid crystal display 34. It will be apparent to those skilled in the art that the interface circuit 60 shown here is one example, and that many alternative and modified circuits that perform the same functionality are possible. Interface circuit 6
0 generates the signals necessary to control the copier so that the information reproduced on the copy sheet has the desired changes different from the original.

(Effects of the Invention) In summary, the editing pad of the present invention stores the information necessary to make changes from an original to a copy sheet, or directly transfers information to the copier to make changes to a copy sheet immediately. It is obvious whether to send it or not. The editing pad includes a digitizer for determining the positional coordinates to be changed, and an overlay menu that allows the photographer to easily manipulate and make desired changes to the copy. In this way, a copy with changes added to the original can be easily reproduced from an electrophotographic copying machine.
