Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a facsimile device that enables partial reading of a document.

In electronic editing facsimile devices that have been developed in the past, before reading a manuscript, the first step is to read a formatted sheet of paper that specifies a portion of the manuscript, and then the area within a predetermined frame is printed on the formatted sheet of paper. A method is adopted in which the reading area is specified or marked in a predetermined field on a formatted sheet. Therefore, such facsimile devices require partially designated format paper to read the original to be sent, and as a result, the types of originals that can be sent are naturally limited to forms, etc., or it is not necessary to write marks on them. The drawback was that it was hot and required time and effort to operate. Another possible method for specifying parts of a manuscript is to cut out the necessary parts and paste them on a separate sheet of paper for reading, but this also requires time and effort and has the disadvantage of damaging the manuscript.

The present invention eliminates the drawbacks of the conventional devices and provides a facsimile device that can easily specify a portion of a document.The present invention will now be described in detail with reference to one embodiment.

FIG. 1 shows a carrier sheet 1 for determining the reading portion of a document. On one side of the carrier sheet, a horizontal scale value 1a and a vertical scale value 1b for giving coordinates of a portion in a two-dimensional plane are constant. It is written using the periphery of the sheet at a pitch of . The line 1c on which the horizontal scale value 1a is written is a synchronization line mark for starting reading, and the line 1d on which the vertical scale value 1b is written is a synchronization mark line representing the main scanning start end. The range of the document read by the facsimile apparatus according to the present invention is assumed to fall within the two synchronization mark lines, and a position designation point is given by the intersection of the scale values in the horizontal and vertical directions from each line.

FIG. 2 shows a state in which an original 2 is set on the carrier sheet 1, and the original 2 is inserted between the base material of the carrier sheet 1 and a translucent cover covering the base material. Figure 3 shows the main body of the facsimile machine (not shown)
Numeric keypad (numeric keys) 3 of the input device provided in
and function key 4, by operating the function key 4, a command for the partial designation mode is given, and further by operating the numeric keypad 3, the designation for reading of the document 2 set on the carrier sheet 1 is given. Location information is input. For example, a case will be described in which, regarding the document 2 shown in FIG. 2, an area surrounded by a frame 5 is designated as a reading portion.

First, the function key 4 is operated to set the facsimile device to a partial reading designation mode. Next, the corner position information of specified range 5 is determined based on the scale written on the carrier sheet.
Specify 5, 2, 2, 4, 1, 4, 1, 5, and 5, 5, and use the numeric keypad 3 to select 22, 52, 2 in sequence.
Enter the numerical information of 4, 14, 15 and 55.
Here, the specified position information gives the position where the reading output signal on the main scanning line needs to be taken out and the operation control position of the pulse motor in the sub-scanning direction, respectively, when the document surface is sequentially main- and sub-scanned. .

FIG. 4 is a circuit block diagram for executing a partial reading operation according to the present invention, in which mode designation and partial designation position information given from an input device A having a numeric keypad 3 and a function key 4 are sent to a central control unit (CPU). ) Once the input is completed, a two-dimensional designated area is calculated from the position information input by central controller B, the range of the part to be read is determined, and the area is stored in memory C via B. is memorized.

In addition, the central controller B turns on the fluorescent lamp E via the light source drive circuit D in response to the read operation start command, and also operates the pulse motor G via the pulse motor drive circuit F to insert the carrier sheet 1 into the carrier sheet 1. The printed original is conveyed together with the carrier sheet 1 to a predetermined position. The light from the fluorescent lamp E reflected from the surface of the document 2 is input to the solid-state image sensor H.
The photoelectrically converted read signal is input to a signal processing circuit, and quantized image information is formed by comparing it with a pre-given slice level, etc., and is stored in a line memory K via an image information mask circuit J. .

The document 2 inserted into the carrier sheet 1 is conveyed line by line by the drive of the pulse motor G.
Synchronization mark line 1c on the carrier sheet is light source E
When the synchronization mark line 1c is sent to a reading position illuminated by the image sensor H, the synchronization mark line 1c is input as an image signal from the solid-state image sensor H to a signal processing circuit, and the central control unit B detects the synchronization mark line. Following the detection of the synchronization mark line, the position of the designated range surrounded by the frame 5 calculated based on the input from the input device A is calculated from the synchronization mark line, and the calculation result is This is converted into the number of motor steps via the pulse motor drive circuit F, and pulse feeding is commanded to the partially specified sub-scanning position. Document 2 after being sent to the desired sub-scanning position by pulse motor G
The surface is scanned, and scanning for reading is performed until the specified range in the sub-scanning direction is completed.

On the other hand, regarding the scanning direction, among the information on the calculated partial reading range, information on the designated range in the main scanning direction is stored in the line memory K, and the stored contents are sent to the mask circuit J during the reading operation of the corresponding main scanning line. The signal read out for each line by the image sensor H is limited to a specified range each time. By repeating this operation, partial reading of the document is executed, and information within the range surrounded by frame 5 is read.

Although the above embodiment has been described with reference to the case where the original is inserted into the carrier sheet, it is also possible to use a manuscript paper or the like with a scale engraved on it that is not detected by the image sensor as a carrier sheet that provides positional information, and the scale can be set finely. This will allow you to specify a more detailed range.

As described above, according to the present invention, when specifying the reading part of a document set in a facsimile machine, all that is required is to operate the part specification mode key and the numerical keys for specifying the position of the area. There is no need to attach marks or marks, and there is no need to cut out the original, so there is no risk of damaging the original, and parts can be specified with a simple operation.
