Title: Facsimile equipment
Inventor: YOSHIDA TAKEHIRO
IPC: H04N1/21
Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To reduce the occurrence of disabled reception even when many reception signals are received by selecting an output for one print-out only not taking much time when a memory residual capacity is small while deferring outputs of a plurality of print-out taking much time for one communication. SOLUTION: The facsimile equipment containing plural lines use a memory 18 to store received information and a button 22 to select outputs of a plurality of print-out so as to execute a plurality of prints out. When the memory reception information is increased and the memory available capacity is less than a prescribed amount, a print-out with a small amount is executed with priority. That is, although print-out of one communication for the reception of an output of a plurality of prints takes much time, when the memory residual capacity is small, the print-out of the received signal for a plurality of prints is deferred, and an output of one print not taking much time for print out is selected, and then the areas for memory reception are soon recovered.  Thus, disable reception is avoided even when many reception signals are received resulting from a plurality of lines to be contained and the opportunity of disable reception is reduced.
