A facsimile apparatus including a cordless telephone set having a remote unit includes photocouplers for detecting whether the handset of a remote unit is at an off-hook condition or not. When the handset is at an off-hook condition, a signal indicating this state is transmitted to a control CPU via the photocouplers and a pair of phototransistors. The control CPU applies a signal from a telephone line monitoring transformer that monitors the condition of a telephone line via a FAX modem. When detection is made that the handset of the remote unit is at an off-hook condition even though the telephone line is under a condition where the communication has terminated, the handset of the remote unit is set to an on-hook condition through a base unit.
L'invention est un télécopieur comportant un téléphone sans fil à unité utilisée à distance qui est doté de photocoupleurs servant à détecter si le combiné de cette unité est décroché. Quand le combiné est décroché, un signal indiquant la chose est transmis à une unité centrale de contrôle via les photocoupleurs et une paire de phototransistors. L'unité centrale de contrôle transmet un signal provenant d'un transformateur qui surveille la condition de la ligne téléphonique par l'intermédiaire du modem du télécopieur. Même si la communication est terminée, quand le combiné de l'unité utilisée à distance est décroché et que la chose est détectée, une unité de base le remet à l'état de raccrochage.
