DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus having image information storage means.

[0002]

2. Description of the Related Art As a conventional facsimile apparatus, a facsimile apparatus having a function of performing reception only from a specific destination has been proposed.

[0003] In this facsimile apparatus, the telephone number of the destination to which reception is permitted is registered in a memory in advance. At the time of reception, it is determined whether the telephone number included in, for example, the TSI sent from the partner transmitter is the telephone number registered in the above memory. Transition. If no registration has been made or no TSI or the like has been sent, the operation does not shift to the image receiving operation.

[0004]

However, in the above-described facsimile apparatus, it is impossible to uniformly receive a destination that is not registered in the memory, and it is difficult to perform flexible operation. There is a drawback that some reception is missed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a facsimile apparatus capable of giving priority to reception from a specific destination while effectively coping with reception from an unspecified destination.

[0006]

According to the present invention, there is provided a registration unit for registering a specific destination in advance, a storage unit for storing received image information, and a remaining amount detection unit for detecting an available remaining amount of the storage unit. When receiving from a destination that is not registered in the registration unit, when the remaining free space in the storage unit is equal to or more than a certain value, the reception is accepted and stored in the storage unit. And reception control means for rejecting the reception.

Further, the present invention further comprises means for detecting the presence or absence of a recording medium for recording image information, and when there is no recording medium, when there is a reception from the destination registered in the registration means. If the remaining free space in the storage means is equal to or more than a predetermined value, the received image information is received by the storage means. Is erased and received by the storage means.

Thus, when there is remaining memory,
Reception from an unspecified partner can also be accepted. The image received in the memory can be confirmed by a list report or output of only the first page.
When the remaining memory is exhausted, priority can be given to reception from a specific destination.
