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 a facsimile apparatus capable of displaying or recording the fact that a partner receiver refuses facsimile communication.

[0002]

2. Description of the Related Art In a conventional facsimile apparatus, when a partner receiver refuses facsimile communication, it is treated as equivalent to a normal communication error, and no distinction is made. That is, when a call by one-touch or abbreviated dialing is selected, it is processed as a pre-procedure error and redial is not performed. Also, when a call using the numeric keypad was selected, a pre-procedure error was also made.

[0003]

However, recently, facsimile machines have become widespread at home, and in order to prevent direct mail, etc., only facsimile is received from a destination registered in one-touch dialing or speed dialing, or Facsimile apparatuses having a function of separately registering a telephone number permitted to receive data and performing reception only from the registered destination are increasing.

For this reason, when an original is to be received by a destination, if the destination receiver operates the direct mail prevention function and the telephone number of the transmission side is not registered as a destination to which reception is permitted. , A communication error always occurs. There is a major drawback that the transmitting operator cannot distinguish it from a normal communication error.

[0005]

According to a first aspect of the present invention, in a facsimile apparatus having an automatic calling function, a communication sequence corresponding to a destination to which an automatic call is made and communication failed in a previous procedure. Means for counting the number of times,
When the automatic call and communication are not established in the previous procedure, the count value corresponding to the other party who made the automatic call is incremented. When the corresponding count value is cleared and a reception good signal or a training failure signal is detected, the counting means is not incremented, and when the count value becomes equal to or more than a predetermined value, the partner receiver performs facsimile communication. It has means for judging rejection and displaying or recording that fact. According to a second aspect of the present invention, in a facsimile apparatus having an automatic calling function, a means for counting a continuous number of communications in which communication is not established in a previous procedure corresponding to a destination to which an automatic call is made;
When the automatic call is established and the communication is not established in the previous procedure, the count value corresponding to the automatically called party is incremented, and when the automatic call is established and the communication is established, the reception good signal or the training is not established. When a signal is detected, the count value corresponding to the other party that has automatically made the call is cleared, and when the count value becomes equal to or greater than a predetermined value, it is determined that the other party receiver has rejected facsimile communication,
Means for displaying or recording the effect is provided.
