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 reduction of transmission time of image information.

[0002]

2. Description of the Related Art In a facsimile machine, when a general document is transmitted, the main scanning line density is usually 8 dots / m.
m, and a sub-scanning line density of 3.85 to 7.7 lines / mm are used. The higher the scanning line density, the better the resolution of the received image. Then, conventionally, an original is read at a designated scanning line density, and image information is transmitted at the read scanning line density regardless of the content of the original. Further, even when the read original is stored in the memory for recalling, image information is stored at the read scanning line density regardless of the content of the original.

For example, when sending a comment page to a fine drawing, the scanning line density is increased in order to send the drawing page finely. Further, when a document to be transmitted is attached to an OMR (optical mark reading device) sheet in which an address or the like is written and is transmitted, if it is desired to transmit the transmitted document with a high scanning line density, the OMR sheet Image information is also read and transmitted at a specified high scanning density.

[0004]

As described above, since image information is conventionally transmitted or accumulated at the read scanning line density, when a plurality of originals are transmitted, only a certain original has a high resolution. If the scanning line density is increased in order to send by, the scanning line densities of all originals will increase. As described above, if the scanning line density is increased even for a document that does not particularly require high resolution, the transmission time when transmitting image information is proportional to the scanning line density, and thus the transmission time is long. It was

Further, if all the originals are read at a high scanning line density and the read image information is stored in the memory as it is, there is a disadvantage that the amount of storage memory used increases.

The present invention has been made in order to solve the above drawbacks, and shortens the transmission time and uses the storage memory by changing the scanning line density according to the content of the original to be transmitted and storing. It is an object of the present invention to obtain a facsimile machine capable of reducing the quantity.

[0007]

A facsimile machine according to the present invention has a density conversion mark discrimination means and a scanning density conversion means, and the density conversion mark discrimination means is a density conversion mark on a document to be transmitted. The scanning density converting means converts the scanning line density of the read document according to the density converting mark judged by the density converting mark judging means.

The above-mentioned density conversion mark discrimination means uses the OMR series.
It is preferable that the scanning line density is reduced and transmitted or stored only when the OMR sheet page is transmitted.

[0009]

In the present invention, the density conversion mark on the original to be transmitted is discriminated by the density conversion mark discrimination means and sent to the scanning density conversion means. The scanning density conversion means converts the scanning line density of the read document according to the sent density conversion mark and sends it to the transmission means or the storage memory, and transmits it at the converted scanning line density or stores it in the memory.

1 is a block diagram showing an embodiment of the present invention. As shown in the figure, the facsimile apparatus 1 has a CPU 2 for managing the entire apparatus, a document reading means 3, a memory 4, a storage memory 5, a transmitting means 6, a density conversion mark determining means 7 and a scanning density converting means 8. .. The memory 4 temporarily stores the image information of the read document. The storage memory 5 stores the read image information when the image information cannot be transmitted because it is busy. The density conversion mark discrimination means 7 discriminates the density conversion mark on the original to be transmitted. The scanning density conversion means 8 converts the scanning line density of the read document based on the result of the discrimination by the density conversion mark discrimination means 7 and sends it to the transmission means 6 and the storage memory 5.

From the facsimile apparatus 1 configured as described above, for example, as shown in FIG.
The operation of transmitting the transmission original 10 with the OMR sheet 12 in which the address and the like are entered to a facsimile server having an OMR recognition processing function will be described with reference to the flowchart of FIG. To do.

The document reading means 3 of the fax machine 1 has a scanning line density designated in advance, for example, a main scanning line density of 8
The dot / mm and the sub-scanning line density are 7.7 lines / mm, and the OMR sheet 12 and the document original 11 are read and temporarily stored in the memory 4 (step S1). The density conversion mark discriminating means 7 discriminates whether the read transmission manuscript 10 is the OMR sheet 12 or the document manuscript 11 from the contents of the transmission manuscript 10 stored in the memory 4, and the judgment result is shown. It is sent to the scanning density conversion means 8 (step S2). When determining the type of the transmission document 11, for example, the OMR sheet 12 or the document document 11 is determined by the start mark of the OMR sheet. The scanning density conversion means 8 sends the discrimination result to the OMR.
In the case of the sheet 12, the sub-scanning line density of the image information on the page is converted into a scanning line density as low as 3.85 lines / mm and sent to the transmitting means 6. The transmitting means 6 transmits the transmitted image information of the OMR sheet 12 at the sub-scanning line density of 3.85 lines / mm (step S3). When the next sent discrimination result is the document original 11, the scanning density converting means 8 sends the sub scanning line density of the image information of the page as the designated scanning line density to the transmitting means 6. The transmitting means 6 transmits the image information of the document original 11 at the designated sub-scanning line density of 7.7 lines / mm (step S4). Then, all the transmission originals 10 are read, and when the contents are discriminated and transmitted, the transmission processing is ended (step S5).

As described above, the image information of the OMR sheet 12 is transmitted at the converted low scanning line density, and the image information of the document original 11 is transmitted at the specified scanning line density, thereby shortening the transmission time. can do.

If the facsimile server or the like of the other party is busy at the time of transmitting the transmission document 10 and cannot be transmitted to the other party, the image information temporarily stored in the memory 4 is stored in the storage memory 5. And send again. In this case, O
The image information of the MR sheet 12 and the document original 11 is stored in the storage memory 5 at the sub-scanning line density determined by the scanning density conversion means 8.

In this way, the OMR sheet 12 accumulates the information at a low scanning line density, and the image information of the document original 11 is accumulated at the specified scanning line density, whereby the amount of use of the accumulation memory 4 is reduced. It can be made small, and a large amount of image information can be stored.

Although the above embodiment has described the case where the transmission original 10 having the OMR sheet 12 and the document original 11 is transmitted, the document original 11 includes originals such as drawings that do not require high resolution. If so, the density conversion mark may be attached to the original to convert the scanning line density and then the original may be sent.

[0017]

As described above, according to the present invention, the density conversion mark on the original to be transmitted is discriminated, and the original requiring the high resolution is transmitted at the high scanning line density, and the high resolution is not required. Since the original is transmitted at a low scanning line density, the transmission time can be shortened and the communication cost can be reduced.

Further, a document requiring a high resolution is stored at a high scanning line density, and a document not requiring a high resolution is stored at a low scanning line density, so that the use area of the storage memory can be reduced. , It is possible to store a large amount of image information.
