Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a copying device such as a printing device, and is particularly applicable to proofreading printed content before printing, and has a suitable display correction function. Pertains to.

Conventionally, the printed content before being printed on paper is read from a memory, displayed on a character display device, etc., modified content is written into the memory, and then the modified printed content in the memory is sent via a printing device. By printing on paper, it was often necessary to proofread the printed content before printing on the paper.

However, in this case, when displaying kanji or the like on the character display device, the number of characters is extremely small, and therefore the content printed once has to be divided into several parts and displayed, which is a troublesome drawback. .

Furthermore, in order to increase the number of characters, it is necessary to increase the display area, that is, the CRT of the display device and the memory capacity of the device, which has the drawback of being extremely expensive and impractical. This device eliminates the above drawbacks.
The object of the present invention is to provide a low-cost copying device that has a display function with a large number of characters and a correction function, and will be described in detail below with reference to the drawings of an embodiment thereof.

FIG. 1 is a schematic diagram of a printing device according to the present invention.

In FIG. 1, A is a recording belt made of electrostatic recording paper, and the recording belt A is wound around belt feed rollers 1, 2, and 3, and travels around while being temporarily stopped at the position of a display window 30. I'm starting to be able to do it. 4 is a charger, and the recording belt A obtains a uniform surface charge layer by the charger 4.

Reference numeral 5 denotes a recording electrode, which partially removes the surface charge layer on the recording belt A according to the printed content read from a page buffer memory (not shown), thereby forming an electrostatic latent layer on the recording belt A. This is where the image is formed.

Reference numeral 6 denotes a developing device that visualizes the electrostatic latent image on the recording belt A using toner, thereby forming a toner image on the recording belt A.

Furthermore, the formed toner image is once displayed on the display window 3 as described above.
It is moved to 0 and displayed there.
Reference numeral 12 denotes an indicator, and the indicator 12 is movably supported within the display window 30, and the horizontal and vertical positions of the indicator 12 can be read electrically.

As will be described later, a page buffer memory (45 in FIG. 2) stores the printed content displayed on the display window 30.
Furthermore, the memory address at which the character indicated by the indicator 12 is stored corresponds to the horizontal and vertical position read.
As a result, the modified contents are written in the page buffer memory 45 according to the storage address and the printed contents are modified, and the modified contents are also displayed at the same time. That is, B is a display belt that displays the correction contents, and if the recording belt A is transparent, the display belt B is
Provided adjacent to its rear side, otherwise to its side.

Reference numerals 7 and 8 indicate belt feeding rollers around which the display belt B is wound. The route B is caused to pass through the positions of the charger 9, the recording electrode 10, the developer 11, and the display window 30 in sequence.

As a result, the display belt B performs the same recording and display as the recording belt A described above, and the static eliminator 21, the cleaner 22
The toner image is removed after display. It is being said. The static eliminator 21 removes the electrostatic adhesion of toner to the display belt B and facilitates the removal of the toner by the cleaner 22. , and a cleaner 20 are provided. 1
Reference numeral 3 denotes a correction recording section, which has the same structure as the static eliminator 19, cleaner 20, charger 4, recording electrode 5, and developer 6.

This also corresponds to the modified page buffer memory 45.
It is also a means for re-recording on the recording belt A the printed contents stored in the recording belt A.

Below, C is plain paper, 16 is a paper feed roller, 14 is a transfer belt made of silicone rubber, etc., and 15 is a transfer roller (
18 is a fixing device, and 17 is a feeding roller. After the toner image on the recording belt A is transferred and fixed onto the plain paper C by these, the toner image is transferred to the printing device. It is becoming more and more excreted.

Next, referring to FIG. 2, a procedure for correcting printed content using this printing device will be explained.

In FIG. 2, 45 is a page buffer memory, and information WRI such as character code and character size is sent to the page buffer memory 45 from a CPU (processing unit), etc.
TE is similarly stored in accordance with the storage address ADDRESS corresponding to the character position sent from the CPU or the like.

The printed content is converted into a predetermined character pattern via the print control circuit 40, recorded on the recording belt A by the recording electrode 5, and then displayed through the display window 30. Further, the indicator 12 is provided with analog-to-digital converters 43, 43a for reading its horizontal and vertical positions, and a predetermined memory address ADDRESS is generated in a decoding circuit 44 from the digital value output of the converters 43, 43a. It's summery.

The characters stored in the page buffer memory 45 are printed according to this memory address ADDRESS, and the display window 3
When displaying starting from 0, the characters are correlated to correspond to the characters indicated by the indicator 12. In addition, 43, 43a
In the case where a pulse motor is used to drive the indicator 12 by commanding horizontal and vertical positions from the keyboard device 40, and inputting the command value of the horizontal and vertical positions to the decoding circuit 44 (in the case shown by the dotted line), The above-mentioned correspondence is made, and therefore the present invention is also applicable to such a case. Now assume that the printed contents of the page buffer memory 45 are displayed on the display window 30 as described with reference to FIG. As shown in FIG. 2, for example, if there is a typographical error 50 "100" in the displayed printed content, the procedure for correcting it to the correct character "1000" is as follows. That is,
First, the indicator 12 is moved to the position of the incorrect character 50 "100".

Next, the character "1000" is pressed on the keyboard 40. In this way, the pressed regular character "1000" is printed by the print control circuit 4.
It is recorded on the display belt B through the zero hexagram and the recording electrode 10 of the display belt B, and then displayed through the display window 30 at the position shown at 51 in the figure.

At the same time, the pressed regular character [thousand] is written into the page buffer memory 45 according to the recording address generated by the decoding circuit 44. As a result, when the correction recording section rerecords on the recording belt A according to the printed content read from the page buffer memory 45, the correct character "1000" is recorded in place b of the incorrect character "100". You can get the same print. As shown in the drawings above, the indicator 12 is mechanically movable, and the modification information is written in the page paper memory 45 using the keyboard device 40, and the modification recording section 1
Although an example using No. 3 has been described, the present invention is not limited thereto.

For example, it is also possible to specify the correction points using a tablet input device.
5 may not be changed, or the correction recording section 13 may be used as the recording electrode 4, the cleaner 20, etc., and the transfer belt 14 may be used to switch between transfer and non-transfer. can. As described above, according to the present invention, it is possible to provide a printing device that allows correction of printed content at an extremely low cost. By configuring the intermediate recording medium so that the display can be viewed directly without using an optical system, the apparatus can be made smaller and simpler.

Furthermore, since there is no need for the trouble of dividing the printing of one page of paper into several parts as in the past, there is a great effect that proofreading and the like can be speeded up.
