Information playback apparatus
View Patent ↗An information playback apparatus is provided to obtain editing effects using an optical disc in the same sense as an analog record disc is manipulated. An audio editing apparatus for playing back an optical disc such as a CD is provided with a rotatable jog dial, detecting device for detecting the amount of rotation of the jog dial, and sensing device for sensing the presence or absence of a pressing force on the jog dial. When the jog dial is rotated while being depressed with a predetermined pressing force, processing for providing sound effects is performed on the playback data to be played back from the optical disc in response to the amount of rotation detected by the detecting device. It is thereby possible to provide the same feeling of operation as provided by rotating an analog record disc through hand operations to produce playback sounds.
1. An information playback apparatus for playing back information from an optical disc, comprising:
an optical pickup for reading information from the optical disc;
a rotating body provided rotatably,
a detecting unit for detecting a rotating speed and a rotating direction of the rotating body,
a sensing unit for sensing a pressure on or a contact with the rotating body;
a control unit for setting a playback speed and a playback direction of the playback information in response to the rotating speed and the rotating direction detected by the detecting unit when the sensing unit has detected a pressure on or a contact with the rotating body;
a memory for storing information read by the optical pickup as memory information;
a judging unit for judging whether the memory information stored in the memory is insufficient;
wherein:
the memory stores predetermined ranges of information before and after information to be read out;
once the judging unit judges that the memory information stored in the memory is insufficient, the optical pickup reads from the optical disc information to be continued with the memory information and stores the read information in the memory.
2. The information playback apparatus according to claim 1 , further comprising an editing unit for performing editing processing to provide a sound effect for playback information, the information having the amount set by the control unit.
3. The information playback apparatus according to claim 1 , wherein
when the control unit determines from the amount of rotation detected by the detecting unit that the rotating body is at rest, the control unit stops the editing processing provided by the editing unit.
4. The information playback apparatus according to claim 1 , wherein
when the control unit determines from the amount of rotation detected by the detecting unit that the rotating body is being rotated back and forth in forward and reverse rotational directions, the control unit causes the editing unit to perform editing processing for providing the playback information with a sound effect in a forward direction in response to the amount of rotation in the forward rotational direction and editing processing for providing the playback information with a sound effect in a reverse direction in response to the amount of rotation in the reverse rotational direction.
5. The information playback apparatus according to claim 1 , further comprising a display unit for indicating the amount of rotation of the rotating body in response to the amount of rotation detected by the detecting unit.
