Abstract

PURPOSE:To attain relay multi-address even without provision of a picture data storage memory by using a control section to control a voice conversion means and a voice data storage means when a facsimile equipment applies relay multi-address. CONSTITUTION:When the reception of a picture data is started at the reception of relay multi-address in a facsimile equipment, a voice A/D conversion LSI 31 applies digital conversion by the control of a communication control section 29 and stores the converted voice data into a voice storage memory 32. When a picture is sent to a multi-address destination, the voice data stored in the voice data storage memory 32 is sent to the voice A/D conversion LSI 31 by the control of the communication control section 29 and analog conversion is implemented and the result is sent to the relay multi-address destination via a line control section 27 and a line 28. Thus, even when a picture data storage memory is not provided, the relay multi-address communication is implemented.
