Title: Tape end detecting device
Inventor: ITO SATOSHI
IPC: G11B15/08
Filed: 2002-07-17
Abstract: <P>PROBLEM TO BE SOLVED: To provide a tape end detecting device in which no further wrong detection is made.  <P>SOLUTION: Resistors R1 to R3 are selectively connected to a phototransistor 82, which is a photodetector, by an electronic switch 12. When a tape cassette is not loaded, a computing section 105 computes the difference between the output voltages of the phototransistor 82 at the time of lighting and turning off of a light emitting element. When the difference becomes less than a comparison value stored in a comparison value storage section 106, a switching control section 101 switches the resistor, which is connected by the switch 12 so that the difference becomes greater than the comparison value. Thus, the photodetection sensitivity by the phototransistor 82 is switched.  <P>COPYRIGHT: (C)2004,JPO
