ABSTRACT:
A facsimile apparatus uses a single memory in a facsimile system and a printer system without using an interface between the two systems. In the facsimile apparatus, a FAX controller stores data received via a communication line. A recording control circuit fetches data from the memory via a data bus, and records an image based on the fetched data. A memory intervention circuit outputs a data bus selection signal, and switches an address of access to the recording medium and a connection of the data bus. Thus, a single memory is shared between a facsimile system and printer system.
