Abstract
Abstract A magnetic tape cassette recording/reproducing apparatus includes a magnetic tape cassette loader which allows easy insertion and removal of a cassette relative to the apparatus and which positively locks the cassette within the apparatus during recording and reproducing operations. The magnetic tape cassette loader includes a cassette holder that is tiltable and slidable relative to the recorder to permit easy insertion and removal of a cassette therein; a handle and latch assembly for handling and latching the cassette holder in the recorder; and an interlock mechanism for locking and unlocking the latch mechanism in response to actuation by a magnetic tape threading apparatus.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
245 words
A magnetic tape cassette recorder comprising: a recorder frame; magnetic tape cassette holding means for releasably holding a magnetic tape cassette; mounting means on said recorder frame for slidably mounting said magnetic tape cassette holding means for linear sliding movement between a first position spaced from said frame and a second position within said frame, said mounting means including means for tilting said holding means, relative to said linear sliding movement when in said first position for facilitating insertion and removal of a magnetic tape cassette with respect to said cassette holding means; cooperative latch means on said recorder frame and on said holding means for latching said holding means in said recorder frame when said holding means is in said second position; interlock means coupled to said latch means for selectively locking and unlocking said latch means; and wherein said recorder includes tape threading means mounted on said recorder frame for removing tape from a cassette held by said holding means at said second position within said frame, wherein said threading means (a) deactuates said interlock means to lock said latch means to prevent movement of said cassette holding means from said second position when said threading means has been actuated and removed tape from a cassette, and (b) actuates said interlock means to unlock said latch means to allow movement of said cassette holding means from said second position when said threading means has been deactuated and tape is returned to said cassette.
Claim 2
Dependent Claim
245 words
A magnetic tape cassette recorder comprising: a recorder frame; magnetic tape cassette holding means for releasably holding a magnetic tape cassette; mounting means on said recorder frame for slidably mounting said magnetic tape cassette holding means for linear sliding movement between a first position spaced from said frame and a second position within said frame, said mounting means including means for tilting said holding means, relative to said linear sliding movement when in said first position for facilitating insertion and removal of a magnetic tape cassette with respect to said cassette holding means; cooperative latch means on said recorder frame and on said holding means for latching said holding means in said recorder frame when said holding means is in said second position; interlock means coupled to said latch means for selectively locking and unlocking said latch means; and wherein said recorder includes tape threading means mounted on said recorder frame for removing tape from a cassette held by said holding means at said second position within said frame, wherein said threading means (a) deactuates said interlock means to lock said latch means to prevent movement of said cassette holding means from said second position when said threading means has been actuated and removed tape from a cassette, and (b) actuates said interlock means to unlock said latch means to allow movement of said cassette holding means from said second position when said threading means has been deactuated and tape is returned to said cassette.
Claim 3
Dependent Claim
66 words
The recorder of claim 1 including handle means on said holding means and coupled to said latch means for selectively moving said holding means between said first and second positions and for selectively actuating said latch means when said holding means is in said second position; wherein when said interlock means selectively locks said latch means, said handle means is prevented from actuating said latch means.
Claim 4
Dependent Claim
93 words
The recorder of claim 1 wherein said magnetic tape cassette holding means includes front, back and side members which form a pocket for holding a magnetic tape cassette, a slide slidably supported in said pocket for engaging a held cassette, wherein said tilting means is coupled to said slide such that when said holding means is in said first position and said holding means is tilted by said tilting means, said slide is slid relative to said holding means to facilitate insertion and removal of a cassette with respect to said holding means.
Claim 5
Dependent Claim
74 words
The recorder of claim 2 wherein said latch means includes a first hook like catch fixedly mounted on said recorder frame and a second hook like catch pivotally mounted on said holding means for engaging said first catch and wherein said handle means includes a spring biased handle and a release lever connected to said handle which is engagable with said pivotally mounted second catch to disengage said second catch from said first catch.
Claim 6
Dependent Claim
80 words
The recorder of claim 2 wherein said latch means includes a hook like catch fixedly mounted on said recorder frame, a catch pin rotatably mounted on said cassette holding means for engaging said catch, and wherein said handle means includes a spring biased handle and a gear train coupled between said handle and said rotatably mounted catch pin, such that actuation of said handle rotates said catch pin through said gear train to disengage said catch pin from said catch.
