Abstract

PURPOSE:To transmit only a necessary part and not to transmit an unnecessary part such as a blank part. CONSTITUTION:A prescribed width band-shaped mark setting area 23 is provided at the left side end of a document 22, for example. Before the document is set on a reading document stand, an official in charge, etc., sets the reading start position (a) and reading end position (b) of a black mark by a marker, etc., at the positions of the mark setting area 23 corresponding to the head part and last end part of the part to be transmitted in the document. The reading of the document is optically executed. A photocoupler 21 which receives reflection light from the mark setting area is properly arranged, light-receiving quantity changes when the reading start position of the black mark reaches the arrangement position of the photocoupler with the movement of the document and a reading start position detecting signal is given to a main control part. Thus, reading is started. Then, a reading end position detecting signal is given to the main control part when the reading end position of the black mark reaches the arrangement position of the photocoupler.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly, to improvement of a method for reading a document surface.

[0002]

2. Description of the Related Art As is well known, a facsimile apparatus is generally designed to transmit the entire set original document sheet as read image information.

[0003]

Therefore, conventionally, there is a problem that a blank portion having no information is also transmitted, which wastes transmission time and wastes recording paper on the receiving side.

It is an object of the present invention to provide a facsimile machine which can send only necessary parts of a document.

[0005]

In order to achieve the above object, the facsimile apparatus of the present invention has the following configuration. That is, the facsimile device of the present invention is a facsimile device that transmits a set document as read image information; forms a mark setting region on the document surface or a document carrier sheet; and starts reading set in the mark setting region. Means for optically detecting the position and the reading end position; and means for reading the contents of the document sheet between the input of the reading start position detection signal and the input of the reading end position detection signal; To do.

[0006]

Next, the operation of the facsimile apparatus of the present invention configured as described above will be described. According to the present invention, the reading start position and the reading end position set on the manuscript paper surface or the manuscript carrier sheet are optically detected, and the manuscript paper surface of the manuscript paper surface between the input of the reading start position detection signal and the input of the reading end position detection signal is detected. Read the content and send it. Therefore, the transmission time can be shortened and the waste of the receiving recording paper can be suppressed.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a facsimile apparatus according to an embodiment of the present invention. In FIG. 1, according to the present invention, the document set on the reading document table 1 is slightly added, and a position detecting section 3 is provided to slightly add a function to a main control section 5 for overall control. .. Other configurations (document reading unit 2, communication control unit 4) are the same as the conventional one. Hereinafter, the description will focus on the part relating to the present invention.

First, the original document and the position detecting section 3 set on the reading original table 1 are as shown in FIG. 2 or FIG. 3, for example. In FIG. 2, the document 22 moves upward with respect to the document reading unit 2, but a mark setting region 23 having a predetermined width band is provided at the left end of the document, for example.
Before the document 22 is set on the reading platen 1, the mark setting area 2 corresponding to the beginning of the portion of the document to be transmitted by a staff member or the like.
The black mark reading start position a is set to the position 3 by magic or the like, and the black mark reading end position b is set by the magic or the like to the position of the mark setting area 23 corresponding to the last end of the portion of the document to be transmitted. I am able to do it.

Although the original 22 is optically read, a photocoupler (which is the position detecting section 3) 21 that receives the reflected light from the mark setting area 23 is arranged at an appropriate position, and the original 22 is read. When the black mark reading start position a reaches the arrangement position of the photocoupler 21 due to the movement, the amount of received light changes, and the reading start position detection signal is given to the main controller 5. As a result, the document reading unit 2 starts reading. Next, when the black mark read end position b reaches the arrangement position of the photocoupler 21, a read end position detection signal is given to the main controller 5. As a result, the document reading unit 2 stops reading.

Further, as shown in FIG. 3, when the original 30 is sandwiched between transparent original carrier sheets 31 and set on the reading original table 1, if the moving direction is the same as in FIG. In the figure, for example, a mark setting region 32 having a predetermined width is similarly provided at the left end, and holes are made at a constant interval (for example, 3 cm) along the moving direction to mark the light source 33 and its sensor 34. The setting areas 32 are arranged so as to face each other. The light source 33 and the sensor 34 are the position detector 3.

A document carrier sheet 31 sandwiching a document 30
Before the sheet is set on the reading platen 1, an attendant or the like sets a reading start position c by closing a hole at a hole position of the mark setting area 32 corresponding to the beginning of the portion of the document to be transmitted with the shielding plate 35. The hole at the hole position of the mark setting area 32 corresponding to the last end of the portion to be transmitted is closed by the shielding plate 36 and the reading end position d is set.

As in the case of FIG. 2, when the reading start position c by the shield plate 35 reaches the position where the light path between the light source 33 and the sensor 34 is blocked by the movement of the document carrier sheet 31 sandwiching the document 30, the amount of received light is reduced. It changes and the reading start position detection signal is given to the main controller 5. As a result, the document reading unit 2 starts reading. Next, when the reading end position d by the shield plate 36 reaches the position that closes the optical path between the light source 33 and the sensor 34, the reading end position detection signal is given to the main controller 5. As a result, the document reading unit 2 stops reading.

By the above operation, only the necessary portion of the original 22 (30) is read, and the image information from the reading start position a (c) to the reading end position b (d) is sequentially transmitted from the communication control section 4. ..

[0014]

As described above, according to the facsimile apparatus of the present invention, the reading start position and the reading end position set on the manuscript sheet or the manuscript carrier sheet are optically detected, and the reading start position detection signal is detected. Since the contents of the document sheet are read from the input to the input of the reading end position detection signal and are transmitted, it is possible to prevent unnecessary portions such as margins from being transmitted, and the transmission time can be shortened.
There is an effect that waste of the recording paper can be suppressed.
