した受信機にて記録することは容易ではない。BACKGROUND OF THE INVENTION As is well known, with the remarkable spread of word processor communication and digital facsimile communication, efforts are being made to promote international standardization of these communications. As part of this effort, it is desired to integrate so-called teletext communication and facsimile communication, but in realizing this, a problem arises in that the scanning line densities of the two communication forms are different. That is,
While facsimile communication uses a line density scan of 8 x 7.7 lines/mm, teletext communication uses a line density scan of 9.45 x 9.45 lines/mm.
Therefore, it is not easy to record an image signal read and decomposed by a transmitter that uses one linear density on a receiver that uses the other linear density.

More specifically, when the maximum width W of the document 2 to be read is, for example, 216 mm, the number of light-receiving elements of the photoelectric conversion device 1 is, for example, 2042, and the image of the line-shaped portion 2a is displayed on these elements. imaged. Therefore, equation 9.45
As can be seen from ×216≈2042, the reading line density in the main scanning direction can be set to 9.45 lines/mm. Also, the pitch of document feeding (sub-scanning) at this time, that is, the distance the document is fed in one intermittent operation, is 1/9.45.
The pulse motor mentioned above is controlled so that the reading line density in the sub-scanning direction is 9.45 lines/mm.

Then, the photoelectric conversion device 1 is brought closer to the original 2 and switched to the position shown in FIG. 1b. As a result, both the object point distance L 1 and the image point distance L 2 are
The object point distance L 1 ′ and the image point distance L 2 ′ are reduced. Here again, assuming that the maximum width W of the original 2 is 216 mm, the image of the line-shaped portion 2a is formed on 1728 light-receiving elements existing in the range indicated by the symbol X in the device 1. Therefore, the reading line density in the main scanning direction can be set to 8 lines/mm (8×216=1728). On the other hand, by controlling the step motor, the feed pitch of document 2 can be adjusted to 1/

The imaging range is switched, and the reading line density in the main scanning direction is selectively changed to a first line density for teletext communication and a second line density for facsimile communication.

行われる。 When recording information transmitted from a transmitter configured for facsimile communication, the first electrode needle array 8 is used. The recording operation itself is exactly the same as that of a known recording device, in which a voltage is selectively applied to each electrode needle 8a in accordance with the image signal, and a dot-shaped charge is placed on the recording paper 4 which has just stopped. It will be done.
This scanning forms a one-line latent image on the recording paper, but at this time, since the pitch between the electrode needles in the first electrode needle row 8 is 125 μm, the direction of the electrode needle row 8 is , that is, in the main scanning direction,
Eight dot-shaped charges can be placed per 1 mm (1 mm/8 = 125 μm). In this way, recording is performed at a line density of 8 lines/mm in the main scanning direction.
On the other hand, as shown in FIG. 5, the rotation of the step motor 12 is caused by a sprocket 1 fixed to its output shaft.
3. The recording paper 4 is transmitted to the feed roller 11 by a sprocket 14 fixed to the feed roller 11 and a chain 15 hooked thereon, so that the recording paper 4 is moved in the direction of arrow A perpendicular to the main scanning direction (in the sub-scanning direction). ), and when stopped, the above-mentioned main scanning is performed, and the pulse motor 12 is controlled so that the feeding pitch of the recording paper 4 is 1/7.7 mm. Therefore, the line density of the sub-scanning is 7.7 lines/mm, and eventually recording is performed at a density of 8 x 7.7 lines/mm, which corresponds to the line density of facsimile communication.

(approximately 105.8μm), i.e. 9.45
Scanning is performed at lines/mm (1 mm/9.45≈105.8 μm). On the other hand, the feed pitch of the recording paper 4 is switched to 1/9.45 mm by controlling the step motor 12, and the line density in the sub-scanning is 9.45 lines/mm. In this way, images are recorded at a linear density of 9.45 x 9.45 lines/mm, making it possible to record images compatible with teletext communication.

3 and 14, the chain 15, and the like constitute a recording medium transport means that transports recording paper, which is an example of a recording medium, in the sub-scanning direction at a linear density corresponding to the linear density in the main scanning direction selected in the recording section. . However, as a conveying means for moving the original or recording paper, any suitable means other than the means shown in the above embodiments can be used, and instead of recording images directly on recording paper, it is possible to use other suitable means for transporting the original or recording paper. It is also possible to form an image once and transfer it to recording paper or the like.

の走査を行うようにする。 Furthermore, in the above-described embodiment, the original or recording paper is fed intermittently, and when it stops, the image is read or recorded. It can also be configured to read or record while it is being moved. In this case, in order to switch the linear density of scanning in the sub-scanning direction, it is sufficient to keep the intermittent movement pitch of the original or recording paper constant, and to switch the reading or recording scanning speed in the main scanning direction performed during this movement. for example,
When the line density in the sub-scanning direction should be reduced,
If one line of reading or recording scanning is performed in the main scanning direction during one intermittent movement of the original or recording paper, etc., when the line density in the sub-scanning direction should be increased, the line density in the main scanning direction should be increased. The scanning speed is increased so that more than one line is scanned in the main scanning direction during one intermittent movement.

The line density in the sub-scanning direction can be switched.

換を為すことができる。 Conventionally, when the reading linear density and the recording linear density are not in the relationship of an integral multiple, for example when reading at a linear density of 8 lines/mm and recording it at a linear density of 9.45 lines/mm, , a difficult function conversion was performed using an electric circuit to convert the linear density, which inevitably resulted in a complicated device configuration.
In the present invention, linear density conversion can be performed with a simple configuration regardless of whether or not the two linear densities are in an integral multiple relationship.
