Description

Description: TECHNICAL FIELD The present invention relates to an image processing apparatus such as a facsimile apparatus.

2. Description of the Related Art Conventionally, there has been proposed a facsimile machine in which data is once input into a memory and checked by a user with a cathode ray tube to obtain a hard copy of only a necessary one. However, the apparatus tends to be complicated and expensive.

There are other proposals such as receiving in 1/4 size, but this is not a basic solution.

There is a proposal to receive the password, but there is a problem when the password is known.

OBJECT The present invention has an object to solve the useless problem of receiving unnecessary information at the time of reception recording of a domestic facsimile which has been a problem recently.

Configuration The present invention utilizes a heat-sensitive recording paper that can erase recorded images and can be reused.

In the spring of 1985, NHK and Mitsubishi Paper Mills react to water and the recorded image disappears, and a reusable thermal recording paper is announced.

It is also known among paper parties that the same can be done with some organic solvents rather than water.

FIG. 1 is a diagram showing the configuration of an embodiment of the present invention.

The original is fed from the original table 1 by the feeding roller 2, and separated by the paper feeding roller 3 and the separating roller 4 one by one.

After that, it advances to the left along the guide plate, is read between the reading head 5 and the feed roller 6, and is then discharged onto the left stacker 7.

The recording side is fed by a feeding roller 10 from a temporary recording paper table 8 which is two recording paper tables and a designated recording paper table (or a cassette may be used) of the permanent recording paper tables 9 like the original document. After being separated one by one by the paper feed roller 11 and the separation roller 12, recording is performed between the thermal head 13 and the feed roller 14, and the paper is ejected to the stacker 7 by the paper ejection roller 15.

Here, although processing of the paper which has been received and recorded but becomes unnecessary becomes a problem, the operability is extremely poor if the image erasing unit is a different device.

According to the present invention, the erasing section is incorporated in the apparatus, and the other transport drive system is also used in common, thereby achieving downsizing and cost reduction.

FIG. 2 is a view showing the structure of a switching plate used in the present invention, in which 16 is a switching plate, 17 is a solenoid, 18 is a fulcrum, 19 is a link, and 20 is a guide plate.

In normal operation, the switching plate 16 is at the position shown by the solid line. When a delete button (not shown) is pressed, the solenoid 17 is attracted and the switching plate 16 rotates left about the fulcrum 18 via the link 19 to switch the transport path.

In FIG. 1, when a recording sheet requiring image erasing is set on the document table with the image surface facing downward, the sensor 21 detects it, and the feeding roller 2 descends like the document and starts feeding.

The sheets separated by the sheet feeding roller 3 and the separating roller 4 one by one are conveyed to the erasing section instead of the reading section by the switching plate 16, and the erasing liquid 23 is applied to the recording surface by the sponge-like erasing roller 22. By doing so, the image is erased.

Further, it is conveyed to the left side, the erasing liquid 23 is removed by the cleaning roller 24, and is discharged onto the stacker 7 to become a rerecordable recording sheet.

Since the cleaning roller 24 is a low price, it also serves as a discharge roller, and the erasing liquid 23 that is attached to the surface or soaked inside may be returned to the plate 25 using a blade or the like.
You may heat or dry naturally.

Further, in the figure, 21 'is a sensor, 26 is a main body of the apparatus, 27 is a sensor unit, 28 is a flow of originals, 29 is a flow of erasing recording paper,
30 shows the flow of recording paper, respectively.

The switching solenoid 17 detects that the last recording sheet on the document table 1 is exhausted by the sensor 21, so that some timing delay is required, but it may be turned off.

There are two types of temporary recording paper (erasable) and permanent recording paper (non-erasable) on the recording paper side, and the user can select which one is required.

If the normal reception (home position) is set to the temporary recording paper side and only those that need to be stored are recorded on the permanent recording paper in the copy mode, the recording paper is not wasted.

Further, it is also possible to specify (for example, with a switch or the like) the permanent recording side and record it only when receiving what needs to be stored.

If you do the same with one chart table, you must set the permanent chart on top of the temporary chart (which cannot be received freely unless the chart is always set due to the nature of the facsimile). Is troublesome.

Although the cut sheet is shown as an example of the permanent recording paper, roll paper may be used. In that case, a cutter is required before or after the recording unit. Further, the paper feeding unit may be only the paper feeding roller and its tension roller, and the feeding roller and the separating roller are unnecessary.

To distinguish the recording papers, printing such as permanent recording may be performed on the upper right of the paper, or may be written at the time of recording. Due to the frequency of use, the manuscript table is arranged in the upper stage where it is most easy to operate, and then the temporary recording paper table (or cassette) is arranged in the middle stage.

FIG. 3 is a diagram showing the configuration of another embodiment of the present invention.

This is because the recording paper table in FIG.
In contrast to the permanent recording paper table 9 and the permanent recording paper table 9, FIG. 3 shows a case where only one recording paper table 31 is used.

The symbols of each part and the operation thereof are basically the same, and therefore their explanations are omitted.

Effects As described above, according to the present invention, it is possible to improve the operability and reduce the cost and size.
