Abstract
Abstract A simplified and easily constructed device for loading and unloading a tape cartridge is disclosed. The device consists of a rotary member rotatably mounted on a chassis. The rotary member has a holder portion positioned for selectively engaging and disengaging a V-shaped notch in a tape cartridge in association with the rotational motion of the rotary member. The rotary member also has a responder portion positioned for being engaged by a cartridge upon insertion and rotating the holder portion into the V-shaped notch. A floating pin and a spring for biasing the pin into contact with a recess in the rotary member are used to restrain the rotational movement of the rotary member and assure a positive loading and unloading of the cartridge.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
189 words
In a cartridge type tape recorder in which a cartridge is located in an operational position by having a holder engage a V-shaped notch in the cartridge, and improved cartridge loading and unloading device comprising: a rotary member rotatably attached to a chassis and provided with a holder means and a responder means, said holder means and said responder means integrally rotatable with said rotary member and said holder means positioned for selectively engaging and disengaging a V-shaped notch in a cartridge in association with the rotational motion of said rotary member, said responder means positioned for engaging a portion of the cartridge upon the insertion thereof and rotating said rotary member; a floating pin disposed movable relative to the chassis; and spring means for urging said pin against said rotary member; said rotary member having at least one recess formed therein for selectively engaging said pin in response to the operation of loading and unloading the cartridge, wherein said pin and said recess restrain the rotational motion of said rotary body and provide a predetermined rotary position for said rotary body, said responder means and said holder means.
Claim 2
Dependent Claim
