发明名称 Time limited data communication system
摘要 A pay facsimile machine, which is similar to a pay telephone, is allowed to be connected to a network for a communication time period, the length of which is determined depending on the amount of money deposited. When the end of the communication time period approaches, a warning signal is given to the user, and if an additional deposit of money is made, the communication time period is extended; however, if no additional deposit is made, the connection is automatically disconnected. If an original document is half transmitted when such a disconnection has happened, the original document is held as it is in a reading unit. When the transmission is resumed, the original document is transported in a forward direction, or, alternatively, is first moved backward for a predetermined distance and then moved forward. A pay facsimile machine is also preferably provided with a remaining time indicating device which indicates the remaining amount of the communication time period either visually or audibly.
