Abstract

(57) [Summary] [PROBLEMS] To provide a public telephone line switch having a facsimile communication function and a facsimile apparatus, which can start transmission to a busy party as soon as communication with the busy party is completed. SOLUTION: When the receiving facsimile apparatus is busy (S4), the telephone number of the transmitting side and the telephone number of the receiving side transmitted from the transmitting side facsimile apparatus are stored in the information memory section of the public telephone line exchange. (S5). When the communication of the receiving facsimile machine is completed (S6), the communication completion information is transmitted to the public telephone line exchange (S7). The public telephone line exchange transmits the received communication completion information to the transmitting facsimile machine (S8). The transmission-side facsimile apparatus starts transmitting the image data stored in the image memory storage unit to the reception-side facsimile apparatus (S
9).

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a public telephone line switch having a facsimile communication function and a facsimile apparatus,
More specifically, the present invention relates to a facsimile transmission method for a busy party.

[0002]

2. Description of the Related Art In a conventional facsimile transmission, when a destination is busy, N times (N = 1, 2, 3,...)
There is a function to redial. In this case, for example, when the other party has been communicating for a long time or communication has been disabled for some reason, after the transmitting side has tried redialing N times, the transmission is eventually unsuccessful. In some cases, the transmission is stopped.

[0003]

However, if the sender has to go out after reading the image into the memory by the memory transmission, if the above-mentioned situation occurs, there is a serious problem. turn into. Further, even if the number of redials is large (the value of N is large), if the facsimile machine of the other party is out of order, the transmission side will make many meaningless redials.

[0004] The present invention has been made in view of the above-mentioned circumstances, and is a public telephone line with a facsimile communication function capable of starting transmission to the other party upon completion of communication with the other party. The purpose of the present invention is to provide a switchboard and a facsimile machine.

[0005]

According to a first aspect of the present invention, when a facsimile apparatus to be transmitted is communicating, the facsimile telephone number of the transmission side transmitted from the facsimile apparatus of the transmission side and the transmission destination facsimile apparatus are transmitted. It has a facsimile transmission information storage unit for storing information on facsimile transmission such as the facsimile telephone number, and monitors and controls information and status on both the transmitting and receiving sides.

According to a second aspect of the present invention, when a destination facsimile apparatus to be transmitted is communicating, a facsimile telephone number of the transmission side transmitted from the transmission side facsimile apparatus, a facsimile telephone number of the transmission destination facsimile apparatus, and the like. Is connected to a public telephone line switch having a facsimile communication function having facsimile transmission information storage means for storing information relating to facsimile transmission of the facsimile transmission, and transmission from the second facsimile apparatus during communication with the first destination. In this case, when the communication with the first destination is completed, the communication completion information is transmitted to the exchange, and the state of the receiving side is grasped.

According to a third aspect of the present invention, in the first aspect of the present invention, when the communication of the destination facsimile apparatus to be transmitted is completed, the communication completion information received from the destination facsimile apparatus to be transmitted is transmitted to the transmission side facsimile apparatus. The state of the receiving side is transmitted to the transmitting side.

According to a fourth aspect of the present invention, when a destination facsimile apparatus to be transmitted is communicating, facsimile transmission of a telephone number of the transmission side transmitted from the transmission side facsimile apparatus and a telephone number of the destination to be transmitted. Connected to a public telephone line exchange with facsimile communication function having facsimile transmission information storage means for storing information about
When the communication completion information of the destination facsimile apparatus to be transmitted is received from the exchange, transmission is started to the destination facsimile apparatus to be transmitted, and non-delivery due to a timeout of memory transmission is prevented. Things.

A data compression / expansion unit 17 for compressing the binarized image data or expanding the compressed data stored in the image memory storage unit to convert it into binarized image data;
Is a system control unit configured with a CPU, ROM, RAM, etc., and controls the entire apparatus. 19 is a display unit that displays information of the operation unit 13 and information of the partner machine. An ADF (automatic document feeder) 21 which conveys the original after scanning and converts the analog signal inputted from the outside into a digital signal and transfers the digital signal to the information memory section and the control section. The unit 22 is an information memory unit for storing information such as the telephone number and status of the facsimile machine transmitted from the facsimile machine through the A / D conversion unit 21. And a control section for controlling facsimile transmission and reception and controlling telephone line connection based on information in the information memory section 22.

FIG. 2 is a flow chart for explaining an embodiment of the public telephone line exchange with facsimile communication function and the facsimile apparatus according to the present invention. FIG.
In the embodiment shown in (1), when memory transmission is started from the transmission-side facsimile apparatus (A) to the reception-side facsimile apparatus (B) (S1), the transmission image data is stored in the image memory storage unit 12 of the transmission-side facsimile apparatus (A). The call is stored (S2), and a call is made to the receiving facsimile machine (B) (S2).
3) If the line of the receiving-side facsimile machine (B) is occupied (S4), the information from the transmitting-side facsimile apparatus (A), for example, the transmitting-side facsimile, is stored in the information memory section 22 of the public telephone line exchange 2. The telephone number of the apparatus (A), the telephone number of the receiving facsimile apparatus (B), etc. are stored and the end of the line use of the receiving facsimile apparatus (B) is waited (S5). When the line communication with the device is completed (S6), the receiving facsimile device (B) sends information to the information memory section 22 of the public telephone line exchange 2 that the line is free (S7).
