た。As described above, in the conventional document holding table, the document 112 is placed on the document table 10.
8, the transparent plate 103 is closed, the original 112 is pressed and held, and when the partial reading of the original 112 is designated, the pointer 110
, And the original 112 is read by an optical system (not shown), which has the following drawbacks.

う問題が生じる。That is, when the original 112 is placed on the original 108 and the partial reading is designated, since there is usually a blank space between the pointer 110 and the frame line in the original 112, the partial reading can be accurately designated. It becomes difficult and the problem that the partial reading area shifts occurs.

稿保持台が得られる。According to the present invention, an original placing table on which an original is placed, a transparent plate for sandwiching and holding the original from above the original placing table, and a reading area of the original are designated. In the document holding table of the image transmission apparatus including the pointers for the document, the document table is composed of a white table partially transmitting light, is formed with ruled lines, and is opposite to the surface of the document table on which the document is mounted. A document holder having a light source that illuminates the surface is obtained.
【０００７】罫線は、とたえば原稿の読み取り領域の主
走査又は副走査方向に平行であるのがよい。The ruled lines are preferably parallel to the main scanning or sub-scanning direction of the reading area of the document, for example.

る。The white table of the document table is a table in which a white paint is applied to a transparent body, or a material itself is white. As a result, when reading a document,
The document is read in the same manner as a white document, and the periphery of the document is prevented from being recorded in black. In addition, since the light from the light source is partially transmitted, the ruled lines rise, which not only makes the positioning of the hands accurate, but also allows the ruled lines to be seen through from the top of the original, making it easy to separate the reading area in the original. Can be determined.

As shown in FIG. 4, a plurality of ruled lines 80 are printed on the surface of the document table 8, and a white paint is applied thereon. The document table may be a white table on which the material itself can partially transmit light. A light source 13 is provided below the document table 8 to irradiate the document table 8 with light from below. This light acts so that the ruled line 80 emerges on a white background of the document table.

るようにすればよい。Next, the operation of the document holding table according to the present embodiment will be described. When the original 12 is placed on the original placing table 8 and partial reading is designated, light from a light source 13 installed below the original placing table 8 is irradiated on the original placing table 8,
The ruled line 80 printed on the document table 8 penetrates through the document 12 as shown in FIG. 4, and the pointer 10 can be accurately specified using the ruled line as a mark. When reading a document, the pointer 10 indicates the document 1
2, the pointer reading information is not processed as an image signal of the document even if the pointer 10 is scanned simultaneously with the scanning of the document. However, when the position of the pointer, particularly the position of the tip of the pointer is detected, the areas D and G between the pointers are detected as shown in FIG.
Only a read scan is performed. For example, a specific mark may be attached to the hands to detect the leading end position of the hands when scanning the original.

Good. Further, although the document holding table 8 can be moved up and down by the coiled spring 7, it may be moved up and down (in a direction perpendicular to the document surface) by a vertical movement mechanism other than the coiled spring 7. For example, it may be electrically moved up and down by an electric motor. Further, an up-down moving mechanism for fixing the document holding table 8 and moving the transparent plate 3 in the up-down direction may be provided instead.
