Description

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

[Prior art 1 Problems to be solved by the invention] Conventionally,
In a facsimile machine that uses a hand scanner, when the thermal head alignment direction is the main scanning direction and the moving direction of the recording paper is the sub-scanning direction, the hand scanner is moved in the main scanning direction on the document to read the document. There is something.

However, this type of device is configured such that the hand scanner stops when the hand scanner reads a width of the document corresponding to the recording paper width of the receiver. Therefore, it is not possible to repeat the reading operation multiple times to send data, and as shown in Figure 8, if the length of the document is longer than the reading width of the hand scanner, it is difficult to read until the end of the hand scanner. There was a problem in that it was unclear which position to move to the reading start position.

The present invention was made by focusing on these problems.
(2) An object of the present invention is to provide a facsimile device that can send a document larger than the reading width of the hand scanner by repeatedly reading it with the hand scanner.

[Means for Solving Problems 1 Effect] The present invention provides a facsimile machine using a hand scanner that moves the document F in the main scanning direction to read the document. This system is equipped with a display section ~ that displays that the scanning width has been scanned. This allows the operator to know from the display that scanning in the main scanning direction has finished, and then move the hand scanner to the next scanning starting position on the document and start scanning. By knowing the end of reading in the main scanning direction and moving to the next reading start position, it is possible to send a document larger than the reading width of the hand scanner.

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

Fig. 1 is a block diagram of a facsimile machine using a hand scanner which is an embodiment of the present invention, Fig. 2 is a mechanical diagram of the hand scanner used in the embodiment, and Fig. 3 is a flowchart showing the operation of the embodiment. It is.

In FIG. 1, l is a communication line connected to a facsimile machine, 2 is a network control unit (NCU), 3 is a well-known modem that modulates and demodulates data, and 4 is a well-known modem that encodes, decodes and decodes image data. This is the CPU that performs IIJ# of the entire facsimile machine. 5 is a ROM memory for storing programs, 6 is a RAM memory for storing data, and 7 is a recording section for recording image data, which is a well-known printer usually used in facsimile machines. 8 is a hand scanner for reading an image; 9 is a main power source for supplying power to each part of the facsimile machine; and 10 is a power switch for turning on/off the main power source. Reference numeral 11 denotes an operation display section for performing operation input and various displays of the facsimile machine, and is composed of a key manual switch and a display such as a liquid crystal display.

In FIG. 2, 12 is a document to be read, 13 is an LED array as a light source, 14 is a line image sensor for reading reflected light from the document, 15 is a motor as a power source for moving the hand scanner, and 16 is a power source for moving the hand scanner. a drive roller, 17, rotated by a moving motor 15;
is a driven roller that moves the hand scanner. 18
is a speaker that outputs a buzzer sound to inform the operator that the hand scanner has read the Li9' manuscript by a width corresponding to the recording paper width of the receiver and has finished reading.

In the above configuration, by turning on the power switch 1G and inputting a destination from the operation display section 11, a dial pulse is sent from the NCU 2 to the line 1 to call the destination. If the called party is set to auto-receive, the CHD
Following the signal, the DIS signal is sent out. If manual reception is set, the DIS signal is sent out when the operator presses the reception button.

In the following, the facsimile apparatus of the present invention is referred to as CCITT.
It is assumed that normal operation is performed according to the T30 standard procedure.

(See Figure 5) The operation will be explained below with reference to FIGS. 1 to 3.

The operator on the sending side sets the hand scanner to the original reading starting position. When the transmitting side detects the DIS signal, it sends out the DC3 and TCP signals.

(See FIGS. 6 and 7) When a CFR signal on the receiving side is detected, a training signal is sent out, one line of the original is read by the line image sensor 14 of the hand scanner, and the CPU 4 stores it in the memory 6. When the hand scanner finishes reading one line, the motor 15 rotates by one line in the main scanning direction, the drive roller 16 rotates by one line, and the next line is read by the line imager 14. In this way, lines are read one after another, and when the document is read in the main scanning direction by a width corresponding to the recording paper width on the receiver side, the image data in the memory 6 is taken out in the main scanning direction, MW encoded, and sent. At the same time, a buzzer sound is output from the speaker 18 to inform the operator that it is necessary to move the hand scanner to the next reading start position. (4th
(See figure) In this way, it is possible to send a document larger than the reading width of the hand scanner.

In the above embodiments, the completion of reading is indicated by a speaker, but a piezoelectric buzzer or a lamp may also be used.

It may be displayed using an LED or the like, and the display section may be provided at a location other than the hand scanner.

Also, although the explanation was given assuming G3 mode, G4°G2. G
1. Transmission in MF mode is also possible. Although transmission is performed using MH code, MR encoding may also be used.

Furthermore, although the hand scanner shown in FIG. 2 is of a self-propelled type, it can also be of a manual type.

〔Effect of the invention〕

As described above, according to the present invention, the hand scanner displays on the display that the document has been read by a width corresponding to the recording paper width of the receiver, and notifies the operator of the completion of reading in the main scanning direction. can be moved to the next reading start position and read, making it easy to feed (ts) a document larger than the reading width of the hand scanner.
