Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
271 words
A cassette loading mechanism for a recording and/or reproducing apparatus comprising: a holder means for holding a recording medium, said holder means being movable in a first direction between a first position at which the recording medium is accepted and a second position, and being movable in a second direction nonparallel to said first direction, between said second position and a third position at which recording and/or reproducing is performed with respect to the recording medium; a first biasing means for biasing said holder means in said first direction; a second biasing means for biasing said holder means in said second direction; a first control means for moving said holder means from said first position to said second position by a biasing force produced by said first biasing means; a second control means for moving said holder means from said second position to said third position by a biasing force produced by said second biasing means; a third control means for controlling said first control means and said second control means to move said holder means from said first position to said third position through said second position, and from said third position to said first position through said second position; a detecting means for detecting an insertion of the recording medium into said holder means at said first position; a drive means for driving said third control means in response to the detection by said detecting means to control said first control means and said second control means; and a drive control means for detecting loading of the recording medium at said third position and for controlling said drive means.
Claim 2
Dependent Claim
271 words
A cassette loading mechanism for a recording and/or reproducing apparatus comprising: a holder means for holding a recording medium, said holder means being movable in a first direction between a first position at which the recording medium is accepted and a second position, and being movable in a second direction nonparallel to said first direction, between said second position and a third position at which recording and/or reproducing is performed with respect to the recording medium; a first biasing means for biasing said holder means in said first direction; a second biasing means for biasing said holder means in said second direction; a first control means for moving said holder means from said first position to said second position by a biasing force produced by said first biasing means; a second control means for moving said holder means from said second position to said third position by a biasing force produced by said second biasing means; a third control means for controlling said first control means and said second control means to move said holder means from said first position to said third position through said second position, and from said third position to said first position through said second position; a detecting means for detecting an insertion of the recording medium into said holder means at said first position; a drive means for driving said third control means in response to the detection by said detecting means to control said first control means and said second control means; and a drive control means for detecting loading of the recording medium at said third position and for controlling said drive means.
Claim 3
Dependent Claim
264 words
A cassette loading mechanism for a recording and/or reproducing apparatus as claimed in claim 27, wherein said first biasing means has a spring, said holder means has a tray that is always biased in said first direction by said spring and a guide member which is attached to said tray and can be raised and lowered, and said tray is supported with a link arm that couples said guide member with a base of said apparatus and coupled to a long hole formed on both sides of said tray at an intermediate position through a pin, said second biasing means has a spring for biasing said link arm in said second direction, said first control means has an arm member rotatably supported on said base of said apparatus and engaged with said tray to control the movement of said tray in said first direction, said second control means has a slidable linkage plate to said pin at said intermediate position of said link arm, said third control means has a first cam for controlling said arm member and a second cam for controlling said slidable linkage plate, said drive means has a worm wheel on which said first and said second cams are formed, and a worm that engages with said worm wheel and a motor for rotating said worm, said detecting means has a switch disposed at a rear of said tray, and said drive control means has a home position detecting switch and a loading completion switch which are activated by said worm wheel to control the rotation of said worm wheel.
