Abstract

PURPOSE:To record all of images of a read original by transmitting the image read by a hand scanner after applying automatic reduction fitting in the width of recording paper of a receiver. CONSTITUTION:The title device is a device operated in such a way that reading width from the start to the completion of reading is detected by the hand scanner instead of transmitting the main scanning line length of recording paper width of the receiver by reading, and the reading width is compared with the recording paper width, and when the reading width is larger than the recording paper width, the automatic reduction is applied on the image of the original stored so that the reading width can be set within the recording paper width, then, the image is transmitted. By such constitution, since the automatic reduction is applied on the image of the original so as to be set within the recording paper width even when the width of the original is larger than the recording paper width, it is possible to record all of the images of the original read on the recording paper, and no separation of the image occurs.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a facsimile machine using a hand scanner.

(Related technology) This type of device scans a document by moving a hand scanner in the main scanning direction, sequentially stores the image signals in memory, and automatically or automatically scans the recording paper on the receiving side. There is a method that manually finishes reading and sequentially retrieves one line of data in the main scanning direction from memory and transmits it. (Refer to Japanese Patent Application No. 62-289375.) On the receiving side, the direction in which the recording paper is fed is taken as the sub-scanning direction, and the direction perpendicular to this is taken as the main-scanning direction.
On the transmitting side, these sub-scan directions.

The direction corresponding to the main scanning direction is the sub-scanning direction.

Main scanning direction.

[The problem that the invention attempts to solve]

However, since the above-mentioned device transmits the data after reading all of the recording paper on the receiving side, as shown in Fig. 5, if the document width is larger than the width of the recording paper on the receiving side, Even if I try to read it, I can only send the first recording sheet.
The remaining part cannot be sent because the reading width does not meet the J self-recorded paper width.
Alternatively, even if all the data can be transmitted, there is a problem that the image on the recording paper may be cut off at the part where the pages span.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a facsimile machine that can record all images of a read document without cutting off the image.

[Means for solving problems]

In the conventional device as described above, the present invention reads the main scanning line length of the recording paper of the receiver and transmits it.
The reading width from the start of reading to the end of reading by the hand scanner is detected, this reading width is compared with the recording paper width, and if the reading width is larger than the recording paper width, the reading width is stored within the recording paper width. This automatically reduces the original image and sends it.

[Effect]

According to this configuration, even if the original width is larger than the recording paper width of the receiver, the image of the original is automatically reduced to fit within the recording paper width, so the entire image of the original read on the recording paper can be recorded, and the image may be cut off. does not occur.

(Example) The present invention will be explained below using examples.

In the configuration shown in FIG. 1 above, by turning on the power switch 10 and manually inputting the destination using the operation display section, dial pulses can be sent from the NCU 2 to the line! and call the destination. C if the called party is set to automatic reception.
A Dis signal is sent out following the HD signal. In the following, it is assumed that the facsimile apparatus of the present invention operates as a normal facsimile according to the CCITT T2O procedure.

The operator on the sending side sets the hand scanner to the original reading starting position. According to the transmission flowchart shown in Fig. 3, when the transmitting side detects the DIS signal, it
Sends CP signal. When a CFR signal on the receiving side is detected, a training signal is sent, one line of the document is read by the line image sensor 14 of the hand scanner, and the CPU
4 to store it in memory. When the hand scanner finishes reading one line, the motor rotates by one line, causing the drive roller 16 to rotate by one line, thereby moving by one line.

In this way, documents are read one after another and stored in the memory. After the hand scanner fails to read to the edge of the document (or any arbitrary position), the operator performs an operation to end the reading from the operation display section, detects the reading width from the start of reading to the end of reading from the image in the memory, The receiving side recording paper width detected by the DIC signal (see Tables 19 and 2 below) is compared with this scanning width, and if the reading width is larger than the recording paper width, the read image is automatically reduced so that the reading width fits within the recording paper width. After performing this, one line of data in the main scanning direction is taken out, subjected to MH cocoing, and transmitted.Then, MH cocoing is performed line by line, and the entire image is transmitted.

In this way, as shown in Fig. 4, even if the width of the original is larger than the width of the recording paper, the image of the original is automatically reduced and recorded on the recording paper, so that the entire image of the original can be recorded without cutting off the image. Can be done.
