There is provided an optical disc reproducing apparatus which reads out data from an optical disc, stores the data, and reproduces the stored data. The apparatus includes: a casing; an operation disc unit for accepting an instruction as to a speed and a sequence for reading the stored data via a rotational operation therewith, the operation disc unit being provided on a surface of the casing; and depression detecting element for accepting an instruction as to a predetermined operation by way of a depression of the operation disc unit, the depression detecting element being provided below the operation disc unit and on the surface of the casing.

Optical disc reproducing apparatus

An optical disc reproducing apparatus including: a reading unit which reads audio data recorded in an optical disc; a storage unit which stores the audio data read by the reading unit; an operation disc unit disposed turnably; a first detection unit which detects the turning speed and the turning direction of the operation disc unit and outputs a first signal indicating the turning speed and the turning direction; a second detection unit which detects that the outer circumference of the operation disc unit is pushed, and outputs a second signal indicating the pushing; and a controller which controls the reading speed and the reading sequence of the stored audio data from the storage unit, on the basis of the first signal when inputted the first signal and the second signal are outputted, and which controls the reading speed of the audio data stored in the storage unit, on the basis of the first signal when inputted only the first signal is outputted.

Optical disc reproducing apparatus and method

The control section determines the rotational direction and the rotational speed of the operation discal unit based on the first pulse signal from the first optical sensor section. When determines that the operation discal unit starts rotating in the reference rotational direction after a pause of at least predetermined period of time, the control section controls the motor to rotate the discal unit temporarily at a speed higher than the reference rotational speed.
