The repeat reproduction is performed by skipping to the position corresponding to the address data. However, since it is necessary to operate the two operation keys of the index button and the backward skip button to set the playback start point and the playback end point, the setting operation of the playback start point and the playback end point is troublesome. Since the playback end point must be set during playback, there is a problem that it takes a long time to set the playback end point.

In the prior art of Patent Document 4, when the halfway playback start position instruction switch is operated during the playback operation, the halfway playback start position given by the address on the memory where the audio data is recorded is stored and set in the RAM. The Thereafter, when the high-speed reverse instruction switch is operated, the halfway reproduction end position given by the address is stored and set. At the same time, the address on the memory is moved backward at a high speed, and when the playback start position is reached, the playback is resumed, and the playback is automatically repeated at a fast playback backward position at the playback end position. ing. However, in order to set the positions of the reproduction start point and the reproduction end point, the two operation keys of the reproduction start position instruction switch and the high speed backward instruction switch must be operated, so that the reproduction start point and the reproduction end point Since the setting operation of the reproduction start point and the reproduction end point must be performed during reproduction, it takes time to set the reproduction start point and the reproduction end point.
