Abstract

PURPOSE:To confirm the talking content recorded during absence in a short time by increasing the tape speed at reproduction more than that at recording. CONSTITUTION:In selecting a switch 38b of a remote controller 8 to the recording position, the talking content recorded during absence is received by a microphone 36 from a mouthpiece of a handset 2b of an external telephone set and it is recorded on a tape by a recording/reproducing head 39 through a recording amplifier 37. When the switch 38b is selected to the recording position, a tape speed control section 40 controls the tape speed at recording as V1 by using the switch 38a. In reproducing the content of recording by the remote controller 8, when the switch 38b is selected to the reproduction position, a signal from the recording/reproduction head 39 is fed to an amplifier 32 via switches 38b, 38c and transduced into sound at a speaker 33. The tape speed controls the tape speed as V2 by using the switch 38a interlocked with the switches 38b, 38c (V1<V2 in this case).
