Dependent claims

A cassette loading device for a tape recorder, comprising:

a deck including two reel driving tables on which tape reels of a tape cassette with a tape shield are seated;
a motor, disposed on said deck, which generates a driving force;
a master gear member which is rotated by said motor;
a holder for receiving said tape cassette;
first and second guide brackets mounted to opposite sides of said deck, respectively, combined with said holder, and having guide slots for guiding said holder along a predetermined path;
a slide member slidably installed proximate to one of said first and second guide brackets, having a first rack gear portion and a second rack gear portion, said first rack gear portion being connected to said master gear member, and which is moved by the rotation of said master gear member;
an arm gear member having a cam gear portion connected to said second rack gear portion of said slide member and an arm portion connected to said holder, and which is rotated to move said holder by the movement of said slide member;
a tape shield opener which opens said tape shield as said holder moves in a vertical direction, said tape shield opener being rotatably installed on one of said first and second guide brackets, said tape shield opener including a shutter member;
a power applying device having a light emitting device installed in the center of said deck, for emitting light, and light receiving devices installed at each side of said deck, for receiving said emitted light, wherein a light passing hole is formed in each of said first and second guide brackets, and said light receiving devices receive said emitted light according to the opening and closing of said light passing hole by said shutter member of said tape shield opener, thereby operating said motor;
