Abstract

PURPOSE:To improve the communication efficiency by providing a charging calculation section selecting a slowest communication speed within a minimum charging based on a dialed number, data of a storage section and data of a memory section to minimize the occurrence of an error. CONSTITUTION:When a telephone number of an opposite party is dialed by an entry section 11 in the case of facsimile communication, an original is read by a read section 5 and stored in a storage section 10. A charging pulse detection section 8 detects a charging pulse sent from a line 4 and sends it to a charging calculation section 7. The charging calculation section 7 calculates the communication charge at the transmission of an original at a standard communication speed (4800 b/s) based on charging data and data stored in the storage section 10. When the communication charge is within one charging unit, the communication speed is set to the standard communication speed. When the communication charge exceeds one charging unit, the charging calculation section 7 increases the speed as 7200b/s and 9600 b/s and calculates the slowest communication speed among communication speeds within one charging unit.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile device, and more particularly to a device for determining the slowest communication speed in a minimum billing unit, transmitting data, and reducing an error rate in transmission.

[0002]

2. Description of the Related Art Conventionally, data has been compressed or the communication speed has been increased in order to minimize the call charge for facsimile communication. For example, if communication is performed at a communication speed of 7200 b / s, even if the transmission original can be sent within the minimum charge unit of the call charge, the communication speed is increased and the same charge is used.
Since the data is transmitted at 400 b / s, the error rate increases. There is a problem because this is done even though it is not necessary to set a high communication speed that causes a high error rate within the same charge.

Embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram showing an embodiment of the facsimile apparatus of the present invention. In the figure, 5 is a reading unit,
The original is read and converted to image data. A storage unit 10 stores the data read by the reading unit 5. A compression unit 1 compresses the data in the storage unit 10 when transmitting the data.
A modem unit 2 modulates the transmission data and changes the transmission speed of the transmission data. Reference numeral 3 is a network control unit, which has functions such as activation / return of an exchange, transmission of a selection signal, reception of a ringing signal, and maintenance of a DC loop. Reference numeral 4 is a line, which is connected to an external facsimile machine (not shown). Reference numeral 11 is an input unit for inputting call billing data for each telephone station and dialing the telephone number of the other party. 9 is a memory part,
Store the entered billing data. A charging pulse detector 8 detects a charging pulse sent from the other party of the telephone. Reference numeral 7 denotes a billing calculation unit, which determines the slowest communication speed within the minimum billing unit from the dial number input to the input unit 11, the data stored in the storage unit 10 and the billing data stored in the memory unit 9. .. Alternatively, the slowest communication speed within the minimum billing unit is determined from the data detected by the billing pulse detection unit 8, the dial number entered in the input unit 11 and the data stored in the storage unit 10. Then, the communication speed at which the data of the modem unit 2 is transmitted is adjusted to the determined communication speed. A control unit 6 controls the reading unit 5, the storage unit 10, the compression unit 1, the modem unit 2, the input unit 11, the memory unit 9, the charging pulse detection unit 8 and the charging calculation unit 7.

In the above configuration, when the telephone number of the other party is dialed from the input unit 11 for facsimile communication,
The document is read by the reading unit 5 and stored in the storage unit 10. The billing pulse detector 8 detects the billing pulse sent from the line 4 and sends it to the billing calculator 7. The billing calculation unit 7 uses this data when there is detection data from the billing pulse detection unit 8, and when there is no detection data, reads the billing data of the dial destination stored in the memory unit 9 and stores it as billing data. From the data stored in the unit 10, the communication charge for transmitting a document at a standard communication speed (for example, 4800 b / s) is calculated. If the communication charge is within one billing unit, the communication speed will be the standard communication speed. When the communication charge exceeds one billing unit, the billing calculation unit 7 outputs 7200 b / s, 96
The communication speed is increased to 00b / s ... to calculate the slowest communication speed among the communication speeds that are within one billing unit. If there is no communication speed within one billing unit, 2 billing units, 3
The calculation is performed by sequentially increasing the charging unit with the charging unit and calculating the slowest communication speed that can be transmitted with the smallest charging unit. The billing calculation unit 7 matches the communication speed for transmitting data of the modem unit 2 with the calculated communication speed. The control unit 6 reads out the data stored in the storage unit 10, modulates it by the modem unit 2, and transmits it via the network control unit unit 3.

[0008]

As described above, in the present invention, since the charge is calculated in the charging unit and the communication speed is not forcedly increased and the communication speed is set to the slowest communication speed within the minimum charge, the error is minimized. It is possible to improve the communication efficiency.
