CASSETTE HOLDER OPERATING DETECTION APPARATUS OF TRAY LOADING MAGNETIC RECORDING/REPRODUCING

PURPOSE: An apparatus for detecting the cassette holder operation of a tray manner magnetic recording player is provided to install a program mode switch to simplify a structure, so as to reduce fabricating cost and to enhance a defective proportion. CONSTITUTION: A tray manner magnetic recording player cover-fixes a cassette housing(20) to an upper part of a deck mechanism, and installs a cam gear(31) in a cassette housing side. The magnetic recording player is coupled with a cassette tray(30) receiving a standard or a small tape cassette having different sizes by a rotating operation of the cam gear(31), to make the cassette tray(30) perform a linear reciprocating moving. A program switch gear(100) is coupled with a predetermined side of the cassette housing(20) to rotate. The program switch gear(100) is in gear with the cam gear(31). An elastic brush is fixed in an inner side of the program switch gear(100). An FPC(Flexible Printed Circuit) attached to an inner side of the cassette housing(20) performs a pattern on a concentric circle connecting with the elastic brush.
