<p>PURPOSE:To attain an overlap sound recording system with no malfunction by setting a means which starts a recording mode for the input signal equal to that of a reproduction part under a recording mode into a matrix switch circuit together with a switch means for remote control line. CONSTITUTION:The overlap sound recording request data is sent in case the recording area of a recording medium is less than a fixed period from the termination at a recording/reproducing part 20a which is in dictation recording mode, and at the same time, the recording mode is forcibly held. While the recording of the same sound signals as those of the part 20a is started at a spare recording/reproducing part 21a. At the same time, a control line is switched from the part 20a and connected. Thus it is possible to attain an overlap sound recording system with no malfunction even in such a constitution where one of the connection lines of a dictation recording/reproducing device is equal to a control line and the current value of this control line is referred to for control.</p> |
