Abstract
A recording or reproducing device includes a pinch roller for pressing a tape-like recording medium against a capstan, a first member for rotatably supporting the pinch roller, a second member for rotatably pivoting the first member, a positioning member for positioning the second member at a predetermined position, and a moving mechanism for moving the second member and engaging it with the positioning member to position the second member at the predetermined position when the tape-like recording medium is loaded. The second member is positioned by engaging a plurality of portions of a shaft for pivoting the first member with the positioning member when the recording medium is loaded.
Claims17
A control device for controlling a pinch roller, in a recording or reproducing device, comprising:
- a capstan;
- a pinch roller rotatable about its axis by engaging with said capstan;
- a first member for supporting said pinch roller at one end of said first member, said first member comprising means for permitting rotation of said pinch roller about said axis, and said first member being movable to an engaging position where said pinch roller engages said capstan and to a non-engaging position where said pinch roller does not engage said capstan;
- a supporting member pivotally connected to an other end of said first member;
- a movable second member pivotally connected to said supporting member, so that said first member and said second member are each independently pivotable relative to said supporting member;
- a positioning member for positioning said supporting member and said second member at a predetermined position against said positioning member where said first member is movable to said engaging position;
- and
- a moving mechanism for moving said second member and said supporting member to said predetermined position against said positioning member;
- wherein said positioning member engages with a plurality of portions of said supporting member to position said supporting member.

A recording or reproducing device for recording on or reproducing from a tape-like recording medium comprising:
- a capstan;
- a pinch roller rotatable about its axis for pressing said recording medium against said capstan;
- a first member for supporting said pinch roller at one end of said first member, said first member comprising means for permitting rotation of said pinch roller about said axis and said first member being movable to an engaging position where said pinch roller engages said capstan and to a non-engaging position where said pinch roller does not engage said capstan;
- a supporting shaft pivotally connected to an other end of said first member;
- a movable second member pivotally connected to said supporting shaft so that said first member and said second member are each independently pivotable relative to said supporting shaft;
- a positioning member for positioning said supporting shaft and said second member at a predetermined position against said positioning member where said first member is movable to said engaging position;
- and
- a moving mechanism for moving said second member and said supporting shaft against said positioning member to position said supporting shaft and said second member at the predetermined position when the tape-like recording medium is loaded;
- wherein said second member and said supporting shaft are positioned by engaging a plurality of portions of said supporting shaft with said positioning member when the tape-like recording medium is loaded.

A recording medium driving device comprising:
- a capstan serving as a driving source for driving a tape-like recording medium;
- a pinch roller for placing the recording medium in a driven state by engaging with said capstan;
- a shaft;
- an actuating member comprising a pair of levers rotatable around said shaft, having respective one lever ends and respective other lever ends at which are formed pressing members for pressing said pinch roller against said capstan at an upper portion and a lower portion thereof;
- a connecting member for movably connecting said lever ends to each other, said connecting member having two connecting member ends each being pivotally attached to each of said respective one lever ends so that said levers have a range of independent rotation around said shaft relative to each other;
- and
- a control member for operating said actuating member by engaging with a central portion of said connecting member to urge said connecting member so as to rotate said levers so that said pressing members press said pinch roller against said capstan.
4 more elements
A recording or reproducing device for recording on or reproducing from a tape-like recording medium comprising:
- a capstan;
- a pinch roller;
- a pinch roller supporting member for rotatably supporting said pinch roller, and capable of moving said pinch roller between a position capable of pressing against said capstan and a position separate from said capstan;
- a shaft;
- an actuating member comprising a pair of levers, disposed parallel to each other and rotatable around said shaft, having respective one lever ends and respective other lever ends at which are formed engaging members engageable with said pinch roller supporting member at upper and lower portions of said pinch roller;
- a connecting member for movably connecting said lever ends to each other, said connecting member having two connecting member ends each being pivotally attached to each of said respective one lever ends so that said levers have a range of independent rotation around said shaft relative to each other;
- and
- a control member for operating said actuating member by engaging with a central portion of said connecting member to urge said connecting member so as to rotate said levers so that said engaging members engage said pinch roller supporting member to press said pinch roller against said capstan.
