Abstract
Abstract A tape cartridge rejection apparatus having a tape cartridge formed with a recess in a side thereof, a leaf spring having thereon a guide member adapted to be urged into the recess to hold in the same position, the urging force exerted to the cartridge by the leaf spring being designed to be released at any desired time, a pushing-out rod for rejecting the cartridge by pushing a forward end thereof so that a rear end of the cartridge is moved beyond a tape recorder body to some extent for thereby disengaging a pinch roller within the cartridge from its pressing contact with a capstan of the recorder whereby the pinch roller is prevented from being deformed. The rejection apparatus is operable either at the termination of a reproducing operation of each of the channels or at any desired time during the reproducing operation thereof.

301 words
A tape cartridge rejection apparatus comprising a tape cartridge housing a magnetic tape, a pinch roller and having a recess in a side thereof, a chassis, cartridge guiding means on said chassis for smooth insertion and withdrawal of the tape cartridge, a retention member mounted on said chassis at one end thereof, urging means for urging said retention member into pressing engagement with said recess in response to a full insertion of the tape cartridge so as to hold the cartridge in position in cooperation with said guiding means, a capstan mounted on said chassis and disposed to press a portion of the magnetic tape against the pinch roller in response to the full insertion of the tape cartridge for driving the magnetic tape, a motor for driving said capstan, a magnetic head mounted on said chassis and disposed at such a location as to contact the magnetic tape in response to the full insertion of the tape cartridge, conductor means for detecting an electrically conductive sensing tape applied to said magnetic tape at a location corresponding to a termination of a reproducing operation of said magnetic tape, an electromagnet mounted on said chassis, an electrical power source for energizing said electromagnet, a first manually operable switch connected in series with said conductor means, a second manually operable switch connected in parallel with the series combination of said first manually operable switch and said conductor means, means for supplying a voltage across said second manually operable switch through said electromagnet from said electrical power source, means for releasing the retention member out of said recess against the urging force of said urging means in response to the energization of the electromagnet, and means on said chassis for pushing out said tape cartridge in response to the operation of said releasing means.
