PURPOSE: To shorten the reproducing time of a video and a voice by making the reproducing speed of the video and the voice with respect to the voice of sections which are not important so much to understanding automatically faster. CONSTITUTION: At a normal time, a control signal generating part 26, in the time of a time shortening reproducing mode, transmits the speed control signal corresponding to the reproducing speed magnification set at the time of starting a reproducing to a motor control part. Consequently, a capstan motor is driven to be rotated at a speed corresponding to the reproducing speed magnification set at the time of starting the reproducing at the normal time. Then, in the time of a time shortening reproducing mode, when the continuation length of the silent section calculated by a silence continuation length calculating part 25 becomes equal to or longer than a prescribed value, the control signal generating part 26 transmits the speed control signal corresponding to a prescribed reproducing speed magnification larger than the reproducing speed magnification set at the time of starting the reproducing to the motor control part. Consequently, in this case, the capstan motor is driven to be rotated at the speed corresponding to the reproducing speed magnification larger than the reproducing speed magnification set at the time of starting the reproducing. That is, the speed of the capstan motor is made faster. |
