Abstract

PURPOSE:To reduce the opportunity of folding an original and to save trouble of making a copy by devising the facsimile equipment to revise the main scanning position. CONSTITUTION:The facsimile equipment is provided with an original platen 1 on which an original 2, a moving optical base 3 with a CCD 5 mounted thereon from which a picture signal is read from the original 2 by main scanning, a drive section 4 moving the optical base 3 in the subscanning direction along the original face, a read period setting circuit 6 shifting a picture signal A for each main scanning line read from CCD 5 by a prescribed picture element number based on a timing signal B and outputting the resulting signal, a timing generating circuit 7 generating the timing signal B and a control section 8 controlling the timing generating circuit 7 based on the information of a read area designated by an operation section 9.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine having an image reading device using a photoelectric conversion element.

[0002]

2. Description of the Related Art An image reading apparatus used in a conventional facsimile apparatus scans an original with a photoelectric conversion element such as a CCD to convert it into an electric signal, and sends it to a receiving apparatus through a communication line to obtain a recording output. .

The original sent by this apparatus has a fixed set position and is fixed depending on the paper size.

[0004]

In the above-mentioned conventional facsimile apparatus, the main scanning start position for image reading is a fixed position. For unbalanced originals, there are drawbacks such as taking a copy and shifting the image in the center or folding and scanning the paper, which is time-consuming and wastes paper.

SUMMARY OF THE INVENTION A facsimile apparatus according to the present invention is a document table on which a document is set, an optical table having a CCD for outputting an image signal read from the document by main scanning, and the optical table. And a reading section setting circuit that moves the image signal for each main scanning line read by the input CCD by a predetermined number of pixels according to a timing signal and outputs the image signal. ,
A timing generation circuit for generating the timing signal;
And a control unit that controls the timing generation circuit based on information of the reading area designated by the operation unit.

The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of an embodiment of the present invention. Moving the original 2 placed face down on the transparent original table 1 Optical table 3
Is moved in the sub-scanning direction by the driving unit 4, and the CCD 5 of the photoelectric conversion element reads the image of the original 2 as the image signal A for each main scanning line and inputs it to the reading section setting circuit 6. The control unit 8 is composed of a CPU and its peripheral circuits, and receives the movement information of the main scanning position from the operation unit 9 to receive the timing generation circuit 7.
Give the navel position information and instructions. The timing generation circuit 7 passes the timing signal B of the main scanning start position to the reading section setting circuit 6 and moves the output timing in the main scanning direction by a predetermined number of pixels according to the position information.

FIG. 2 is a timing chart for explaining the operation of this embodiment. When there is no instruction from the operation unit 9, the valid signal c at a predetermined position is output from the reading section setting circuit 6 in synchronization with the image signal a and its clock b.

When the operation section 9 gives an instruction to change the position in the main scanning direction, the control section 8 gives an instruction to the timing generation circuit 7, and the timing generation circuit 7 outputs the timing signal d.
Is output. The reading section setting circuit 6 to which the timing signal d is input creates an effective signal e for changing the output timing of the image signal a, and sends the image signal in the effective section to the image processing unit.

By doing so, as shown in FIG. 3, an image signal in which the position of the written image drawn on the transmission original P is corrected is transmitted from the transmitting side, and the receiving image R is received at the center of the recording paper by the receiving side device. Can be recorded as

[0010]

As described above, according to the present invention, a document table on which a document is set, an optical table equipped with a CCD for outputting an image signal read from the document by main scanning, and the optical table on the document surface. A driving unit for moving in the sub-scanning direction, a reading section setting circuit for moving the image signal read by the input CCD for each main scanning line by a predetermined number of pixels according to the timing signal, and outputting the image signal are generated. By having the timing generation circuit and the control unit that controls the timing generation circuit based on the information of the reading area designated by the operation unit, it is possible to move the position of the writing image drawn on the transmission original and transmit it.
