The central processing unit 140 determines whether or not the reception is possible according to the signal of the state sensing unit 110 and the memory control unit 130, and operates a reception mode selected by the user when a ring signal is detected. When the signal of the central processing unit 140 is incapable of receiving, a communication error is generated, and the network control unit 160 is controlled through the reception control unit 170 to block the line.

The reception control method for a fax according to the prior art includes a first process of checking whether a received recording paper is exhausted and a state of a memory space as shown in FIG. 2, a second process of checking whether a ring signal is detected, and a reception process. A third process of selecting and performing a mode and a fourth process of generating a communication error if it is impossible to determine whether data can be received.

In the third step, in the automatic mode, the receiving protocol is performed after connecting the line. In the manual mode, the receiving protocol is performed when the user enters a communication start key after talking through the telephone.

In the fax / telephone exchange mode, the receiving protocol is performed when a fax signal is detected by connecting a line. In the answering machine mode, the answering machine is operated by operating the answering machine. Proceed.

The prior art as described above has a problem in that unnecessary communication charges are generated because the system enters a reception mode and generates a communication error even when the system is in an unreceivable state.

The present invention has been made to solve the above problems, and checks whether the receiving recording paper is exhausted and whether the cover is open and the available space of the memory at all times to determine whether reception is possible before connecting a line to generate a communication error. It is an object of the present invention to provide a reception control apparatus and method for preventing faxes.

The reception control apparatus and method for a fax according to the present invention for achieving the above object include a state detection unit for checking whether the reception recording paper is exhausted and whether the cover is open, a memory unit for storing received data, and the memory; A memory controller which controls the data storage of the unit and checks the state of the memory space, a central processor that controls the entire system by inputting the output signals of the state sensor and the memory controller, and determines a reception mode to send a signal to the central processor. A reception mode determination unit for inputting, a network control unit for determining whether to connect to an external line, and a reception control unit for controlling the network controller by receiving a control signal of the central processing unit when a ring signal is detected from the network controller. A first process of selecting a reception mode by a user, and a second process of checking whether a ring signal is detected; When the ring signal is detected as a result of the second process, the second process performs a reception mode according to a reception possible state.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the reception complete voice transmission device for fax according to the present invention will be described in detail.

According to the present invention, as shown in FIG. 3, the state detecting unit 10 which checks whether the received recording paper is exhausted and the cover is opened, a memory unit 20 storing the received data, and the memory unit 20 A memory controller 30 for controlling data storage and checking the state of the memory space, and a central processor 40 for controlling the entire system by inputting output signals from the state sensor 10 and the memory controller 30. And a reception mode determination unit 50 for determining a reception mode and inputting a signal to the central processing unit 40, a network control unit 60 for determining whether to connect with an external line, and the network control unit 60. When the ring signal is detected, the control signal of the central processing unit 40 is input to perform a reception mode and is configured as a reception control unit 70 for controlling the network control unit 60.

According to the present invention configured as described above, the state detecting unit 10 and the memory control unit 30 check whether the received recording paper is exhausted, whether the cover is opened, and the state of the memory space, and the central processing unit ( In 40), it is determined whether or not the reception is possible.

In this case, the reception mode determination unit 50 determines a reception mode, and when the ring signal is detected by the network controller 60, performs the predetermined reception mode. When the central processing unit 40 is in a reception disabled state, the reception control unit The line is controlled by controlling the network controller 60 through 70.

Hereinafter, a reception control method for a fax according to the present invention will be described in detail with reference to the flowchart shown in FIG.
