DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus, and more particularly to an apparatus for thinning out contents written on a transmission original and transmitting the same at a reference time.

[0002]

2. Description of the Related Art Conventionally, when a document is transmitted in facsimile communication, the data amount after image data compression varies depending on the content (how a black portion appears) of the document. The data amount is directly proportional to the communication time. That is, a document having a large amount of information has a long transmission time, and a document having a small amount of information has a short transmission time. When a document with a large amount of information is transmitted over a long distance, the communication fee is high. If the contents written in the manuscript are thinned out and transmitted, the communication fee can be greatly reduced, and the appearance of such a communication device has been desired.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems. When the call time of a transmitted document exceeds a reference time, the contents written in the document are thinned out and transmitted. Reduce fees.

A setting unit, a reading unit for reading a document, a storage unit for storing the read data, a compression unit for compressing the stored data, a memory unit for storing the compressed data and the telephone number, and a telephone for the memory unit. A comparison unit that calculates a thinning rate by comparing the transmission time of the reference time setting unit corresponding to the number with the transmission time of the compressed data in the memory unit, and thins out the data in the storage unit based on the thinning rate of the comparison unit A thinning unit, a modem unit for compressing and modulating the thinned data by the compression unit, and an input unit, a reference time setting unit, a reading unit, a storage unit, a memory unit, a comparison unit, and a thinning unit. Facsimile apparatus characterized by being constituted by a control unit which

[0005]

According to the above arrangement, the reference time for each area code is inputted from the input section and stored in the reference time setting section. The telephone number of the party to which the original is to be transmitted is input from the input unit and stored in the memory unit, and the original is read by the reading unit and the read data is stored in the storage unit. The stored data is compressed by the compression unit and stored in the memory unit. The comparing unit compares the reference time of the reference time setting unit corresponding to the telephone number of the memory unit with the transmission time of the compressed data in the memory unit to calculate the thinning rate. The thinning unit thins the data in the storage unit according to the thinning rate. The thinned data is compressed by a compression unit, modulated by a modem unit, and transmitted.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram showing one embodiment of the facsimile apparatus of the present invention. In the figure, reference numeral 11 denotes an input unit for inputting a telephone number of a partner and a reference time for each area code. Reference numeral 10 denotes a reference time setting unit which stores the input reference time for each area code. A reading unit 8 converts a transmission original into read image data by a reading unit. A storage unit 7 stores the read data. A compression unit 1 compresses data read from the storage unit 7. A memory unit 5 stores the compressed data and the telephone number input to the input unit 11. A comparison unit 12 compares the reference time of the reference time setting unit 10 corresponding to the telephone number with the transmission time of the compressed data stored in the memory unit 5 to calculate a thinning rate. A thinning unit 9 thins out data stored in the storage unit 7 according to a thinning rate and compresses the data with the compression unit 1. Reference numeral 2 denotes a modem unit for modulating the compressed data. Reference numeral 3 denotes a network control unit, which has functions such as starting and restoring the exchange, transmitting a selection signal, receiving a call signal, and holding a DC loop. 4
Is a line connected to an external facsimile machine (not shown). A control unit 6 controls the input unit 11, reference time setting unit 10, reading unit 8, storage unit 7, compression unit 1, memory unit 5, comparison unit 12, thinning unit 9, and modem unit 2.

In the above configuration, a reference time for each area code is input from the input unit 11. For example, the reference time for the Tokyo station number is 3 minutes, the reference time for the Shizuoka station number is 2 minutes, and the reference time for the Osaka station number is 1 minute. The input reference time for each area code is stored in the reference time setting unit 10. Next, the telephone number of the other party to be transmitted is input from the input unit 11, and the transmission original is read by the reading unit 8. The read original is converted into image data and stored in the storage unit 7. The data stored in the storage unit 7 is compressed by the compression unit 1 and stored in the memory unit 5. The comparison unit 12 reads the input telephone number, for example, a reference time of 2 minutes corresponding to the Shizuoka station number from the reference time setting unit 10 to calculate the transmission time of the compressed data stored in the memory unit 5 and compares the two. . If the transmission time of the compressed data is 2 minutes or less, it is transmitted as it is. If the transmission time of the compressed data is 2 minutes or more, for example, if it is 4 minutes, the thinning rate is 50% (2 minutes / 4 minutes × 10
0%). If the thinning rate is significantly increased, the original after thinning becomes difficult to read, so the maximum thinning rate is, for example, 67% (three lines of image data are thinned out for two lines). If the transmission time of the compressed data is 6 minutes, the thinning rate is 67%, and if the thinning is performed, the time is 2 minutes. If the transmission time of the compressed data exceeds 6 minutes, it is decimated at the maximum thinning rate, and the transmission time exceeds 2 minutes of the reference time of the Shizuoka station number. Thinning section 9
Decimates the image data in the storage unit 7 at the decimation rate calculated by the comparison unit 12. The thinned data is compressed by the compression unit 1, modulated by the modem unit 2, and transmitted from the line 4 via the network control unit 3.

[0008]

As described above, in the present invention, the reference time is set shorter as the distance becomes longer, so that the communication fee can be made the same regardless of the distance, and the effect of reducing the communication fee is great.
