Cassette type audio data or signal recording and reproducing apparatus
First Claim
1. A cassette type digital audio data recording and reproducing apparatus comprising:
- a speed and direction detection sensor for detecting the speed and direction of a winding reel or rewinding reel and generating a detection output corresponding to the speed and direction;
a memory where a digital audio file is recorded or stored;
a controller for controlling the reading and decoding of the digital audio file stored in the memory, or the recording of the digital audio file, based on the detection output generated from the speed and direction detection sensor;
a D/A converter for converting a digital audio file decoded by the controller to an analog audio file;
a head for converting the audio signal converted by the D/A converter to a magnetic signal;
a head pressing detection sensor for detecting the pressing of the head and supplying a detection output signal to the controller; and
a power supply portion having a battery for supplying DC power and a DC-to-DC converter for converting DC power supplied from the battery to a predetermined DC power and outputting the converted power when the detection output signal of the head pressing detection sensor is supplied to the controller, wherein after the power is supplied from the DC-to-DC converter, the controller checks whether the winding reel or the rewinding reel rotates and is shifted to a power saving mode for minimizing power consumption of the battery if the above reels do not rotate after a predetermined time passes.
