43 to S57) and the operation (steps S58 to S63) from when the recording conditions are completed to when printing is completed, may be synchronized or asynchronous, respectively. , Or by software, electrical, or optical.

[0049]

As described above, according to the present invention, based on the remaining amount of the image information storage memory capable of storing the current image data at the start of reading of the original and the original size and resolution of the original to be read from now on. If the original size and resolution of the image information to be stored in the image information storage memory are changed, the image information is stored in the image information storage memory after the image information is reduced, and when the transmission is started to the partner facsimile apparatus, The determined resolution and document size are compared with the paper size of the document actually stored at the time of document reading and the resolution set by the operator and the paper size and resolution of the actually stored document at the time of document reading. To get the resolution and manuscript size you think,
Since the stored image information is configured to be enlarged and complemented and transmitted, the possibility of occurrence of memory full which restricts the operation involving storage in the image information memory is reduced, and transmission determined by the communication procedure is performed. It is possible to obtain image quality according to the linear density and recording width capability of the other party.

Further, if configured as in claim 2,
Not only does the probability of memory full occurring at the time of reading operation on the transmitting side decrease, but also the probability that memory full occurs at the receiving side decreases, there is no restriction on operation, and the original document that the transmitting side desires at the time of reading Image quality of size and resolution can be easily obtained.
