Description

The present invention relates to an image communication device.

2. Description of the Related Art In a conventional apparatus of this type, for example, a memory facsimile apparatus capable of setting a plurality of recording paper sizes, when a recording paper is set, a receiving operation is started and a recording operation is started. . That is, the currently set recording paper size (a facsimile apparatus capable of setting a plurality of recording papers at a time, the largest recording paper size among the currently set recording paper sizes) is transmitted to the partner machine by a procedure signal. Recording is performed with the information size specified by the transmitter for actual transmission. In a facsimile apparatus capable of setting a plurality of recording sheets at a time, recording is performed by selecting a recording sheet having an information size specified by the transmitting side and actually transmitting. Here, when the recording paper of the information size specified by the transmitter is not set, the recording is performed on the recording paper larger than the information size specified by the transmitter. Specifically, it is assumed that, for example, A3 size and B4 size are set as recording paper. At that time, first, the facsimile apparatus of the other party is notified by the initial identification signal that the A3-size recording paper is set. When an instruction to transmit information in A3 size is received from the transmitter by a reception command signal, A3 size recording paper is selected for recording. When an instruction to transmit information in B4 size is received from the transmitter by a reception command signal, B4 size recording paper is selected for recording.
When an instruction to transmit information in A4 size is received from the transmitter by a reception command signal, B4 size recording paper is selected for recording. Since there is no A4 size recording paper, the smallest size among the recording paper sizes (B4 size and A4 size in this example) larger than this size (A4), that is, the B4 size is selected.

[Problems to be solved by the invention]

However, in the conventional device, for example, the receiving device is
Although the A3 size recording paper is set to A4, the A3 size recording paper can be transmitted at A3 same size, but the A4 size recording paper is set even though it has A3 equal size receiving ability. Therefore, it is reduced.

Also, if A3 size paper is set and the size of the original on the transmitter is A4 size, the A3 size paper will be used.
Since the A4 size information is recorded, the recording paper cannot be effectively used, resulting in increased waste.

[Means (and action) for solving the problem]

According to the present invention, there is provided control means for comparing the size information sent from the other party with the recording paper size set in the setting means, and storing the received image data in the storage means when both sizes are different. Thereby, the recording paper is wasted and the image communication can be appropriately performed.

〔Example〕

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In the following embodiment, a facsimile apparatus will be described as an example.

First, recording paper sizes that can be set in the memory facsimile apparatus of the present embodiment are A3 size, A4 size, and A4 size. At the same time, one recording paper can be set. When the receiving operation is selected, the receivable size is set to the maximum settable recording paper size, that is, A3 size, regardless of the currently set recording paper size, by a procedure signal to the other party facsimile machine. Notify that there is.

If the currently set recording paper size is the same as the information size sent from the other party, recording is performed. If the currently set recording paper size is different from the information size sent from the other party, the received information is stored in the memory, and the fact that the information has been received and the document size are displayed. This display is performed for each notification. The communication number initially stored in the memory is set to the communication number 1, and thereafter, each time communication is performed, the communication number is sequentially increased to 2,3. Then, in a state where a plurality of communications are stored (for example, 10 communications), when the recording of the communication in the middle is selected (for example, when the recording of the communication with the communication number 5 is selected), the selected communication is selected. After the recording of the communication number is completed, the subsequent communication numbers are rounded up (for example, the communication number 6 is changed to 5, the communication number 7 is changed to 6, the communication number 8 is changed to 7, and the communication number 9 is changed to 8
And the communication number 10 to 9). As for the received information stored in the memory, when a communication number to be recorded is input from a numeric keypad and a memory information recording start button is pressed, the communication of the designated communication number is recorded. If the memory information recording start button is pressed without inputting the communication number for recording from the numeric keypad, all stored communications are recorded.
