Abstract

PURPOSE: To provide a facsimile equipment in which a black level image at a peripheral part caused when a book original is read is trimmed. CONSTITUTION: A trimming amount to eliminate a black image at the peripheral part caused when a book original is read is set by mechanical covers 401, 402 or scales 501, 502 and the image within the set range is replaced into a white level image. The position of the scales may be measured mechanically by using a gear 506 and an encoder or the like or an image read means for reading an original may read the position. Or whether or not all full black level lines or lines with a prescribed ratio or over of black level image are in existence at the surrounding part of a read image is judged and when they are in existence, the lines may be replaced with full white lines. Or a black image of a prescribed length or over at the start or end in the main scanning direction may be replaced with a white image.

A book manuscript is set on the book manuscript table on which the manuscript cover is placed (S1002). When the sheet original is set in the sheet reading unit (S1003), the fact is displayed on the display unit 302 as an alarm (S1004). This makes it possible to avoid unnecessary reading.

If there is no sheet original, it is judged whether or not a plurality of copies are required (S1005), and if necessary, the number of copies is set (S1006), and a display for pressing the start key to start copying is displayed (S1007). ). S100
Since the trimming amount is determined by the lid specified in 1,
If the normal reading operation is performed without performing the soft processing, the edge portion (shadow etc.) of the document can be trimmed.

(Embodiment 3) FIG. 5 is an explanatory diagram of trimming based on count values by a ruler (main scanning ruler and sub-scanning ruler) on a document table according to the present invention. The original 503 is set on the book reading original table. The main scanning ruler 501 is slid in the main scanning direction, the sub scanning ruler 502 is slid in the sub scanning direction, and necessary trimming is performed by aligning with the original. When the main scanning ruler 501 is moved, the main scanning ruler 5
The connecting wire 505 connected to 01 operates the gear 506. The counter 507 counts the rotation of the gear 506, determines the trimming amount (trimming amount), and notifies the central control unit. Similarly, the sub-scanning ruler 502 is also connected to the gear, and the counter 507 reads the number of rotations thereof.

FIG. 11 is a flow chart for setting the reading size of the book original with a ruler. A book document is set on the book document table (S1101). Slide the main-scanning ruler and sub-scanning ruler on the platen to the desired position. The central control unit judges the information from the counter which is linked with the trimming ruler to determine the trimming amount (S11).
02).

When the sheet original is set in the sheet reading unit (S1103), the fact is displayed on the display unit 302 as an alarm (S1104), whereby unnecessary reading can be avoided. If there is no sheet original, it is determined whether a plurality of copies are required (S1105), and if necessary, the number of copies is set (S1106), and a display for pressing the start key to start copying is displayed (S11).
07). As a result, it is possible to read the document with the trimming amount specified in S1102 and process the edge (shadow, etc.) of the document.

It is also possible to preset the end mark on the reading side of the ruler and optically determine the position of the trimming ruler to obtain the trimming amount. At the time of reading a document, the central control unit determines the end mark in the main scanning direction and the end mark in the sub-scanning direction, and processes the end portion (shadow, etc.) of the document. In this case, there is an effect that the gear and the counter can be omitted, and the device can be downsized and the cost can be reduced.

(Embodiment 4) FIG. 12 is a flow chart for explaining sub-scanning trimming control on the receiving (printing) side. Data for each line is read from the image memory and checked (S1201), and it is determined whether or not there is a black line (all black line) in all the data (S1).
202), if there are all black lines, it is determined whether the number of continuous all black lines is equal to or more than a specified number (S1203).

If there is no all black line in S1202, or if there is an all black line in S1202, S1
If the number of lines is less than the specified number in 2003, it is determined that the data is normal data and those lines are printed (S120).
4). It is determined whether printing of all the lines on one page is completed (S1205). When the printing of one page is completed in S1205 or the continuous black line of the specified amount is detected in S1203, the process is completed.

(Embodiment 5) FIG. 13 is a flow chart of control for removing the shadow of the end portion of the document on the main scanning side. Data for one line is checked from the image memory (S1301). When the black data from the start point is larger than the predetermined value (S1302), the black data for the predetermined value from the start point is replaced with the white data (S1303). When the black data from the end is larger than the predetermined value (S1304), the black data for the predetermined value from the end is replaced with white data (S130).
5). Then, processing for one line (S1306) is performed and it is determined whether one page is finished (S1307).

By performing this processing on the transmitter (reading) side, it is possible to reduce the amount of communication data, communication time, and the like. Also, by inquiring on the protocol whether or not the receiver side has a trimming function, the transmitter side can transmit the read information as it is and the receiver side can perform trimming, so that the flexibility of the receiver side is improved. It is also possible to remove the black image area itself in the peripheral portion of the image and send it as a small image. In this case, it is possible to eliminate the time for transmitting the white image in the peripheral portion. In this case, by notifying the receiver of the position of the trimmed image in the original image, the receiver can print at the same place as the original image.

(Others) Instead of judging all black lines in the fourth or fifth embodiment, it is judged whether or not a predetermined ratio, for example, 95% or more is black, and a line in which a predetermined ratio or more is black is selected. You may count. In this case, even if a white image is mixed due to dust or the like, the area where the book document does not exist can be replaced with the white image.

[0063]

As described above, according to the facsimile apparatus of the present invention, the shadow image (black image) at the edge of the book original is deleted. The amount of data to send is reduced.

2. Therefore, the communication time is reduced.

3. Furthermore, communication costs will decrease.

4. In addition, the amount of ink during printing is reduced.

5. Therefore, the printing time is reduced.

6. In addition, running costs are reduced.

In particular, according to the method described in the first embodiment, the user sets the original size from the operation panel, so the original reading size becomes clear and unnecessary images are not read.

According to the method described in the second embodiment, since the user sets the document size on the document table, the reading amount of the document becomes clear and unnecessary image loss does not occur.

According to the method described in the third embodiment, the cost performance is good because the trimming can be performed only by changing the software. In addition, since the user does not need to set the trimming amount, operability is good.

According to the method described in the fourth embodiment, since trimming processing is performed on the receiving (recording) side, unnecessary black line printing is avoided even when the conventional transmitter (reading) is used. Can be done.

According to the method described in the fifth embodiment, the cost performance is good because only the software needs to be changed. Further, since the user does not need to set the trimming amount, the operability is improved.
