Abstract
Abstract A magnetic recording and reproducing apparatus has a housing with a movable section including a cassette holder for moving a magnetic tape cassette between an operative position and an eject position, a magnetic head assembly for carrying out the recording and reproducing operations on magnetic tape withdrawn from the operatively positioned cassette and a tape loading mechanism for loading or unloading the magnetic tape on or from the magnetic head assembly. The movable section is slidably movable in the horizontal direction between an open position where the movable section extends forwardly from the housing and a closed position where the movable section is contained within the housing. When the cassette holder is held in the operative position, the movable section can be positioned at the closed position with the housing. Further, the tape loading mechanism and the cassette holder are operated in correspondence with the motion of the movable section.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
183 words
A magnetic recording and reproducing apparatus, for recording or reproducing a signal on a magnetic tape contained in a tape cassette, comprising: a housing including a front panel having an opening formed therein; and a movable section including support means movable substantially horizontally through said opening between an open position in which said movable section extends forwardly from said housing and a closed position in which said movable section is contained within said housing; said movable section further including cassette mounting means for receiving said cassette and moving said received cassette relative to said support means between an operative lowered position in which the cassette can move through said opening and a raised eject position out of said housing and in which said cassette may be removed from said apparatus, and a magnetic head assembly mounted on said support means for movement therewith and being adapted for recording or reproducing a signal on the tape of a cassette in said operative position; said cassette mounting means holding said cassette in said operative position when said movable section is moved to said closed position.
Claim 2
Dependent Claim
183 words
A magnetic recording and reproducing apparatus, for recording or reproducing a signal on a magnetic tape contained in a tape cassette, comprising: a housing including a front panel having an opening formed therein; and a movable section including support means movable substantially horizontally through said opening between an open position in which said movable section extends forwardly from said housing and a closed position in which said movable section is contained within said housing; said movable section further including cassette mounting means for receiving said cassette and moving said received cassette relative to said support means between an operative lowered position in which the cassette can move through said opening and a raised eject position out of said housing and in which said cassette may be removed from said apparatus, and a magnetic head assembly mounted on said support means for movement therewith and being adapted for recording or reproducing a signal on the tape of a cassette in said operative position; said cassette mounting means holding said cassette in said operative position when said movable section is moved to said closed position.
Claim 3
Dependent Claim
43 words
A magnetic recording and reproducing apparatus according to claim 1, wherein said cassette mounting means includes cassette holding means for receiving said cassette, said cassette mounting means moving said cassette holding means relative to said support means between said operative and eject positions.
Claim 4
Dependent Claim
72 words
A magnetic recording and reproducing apparatus according to claim 2, wherein said tape cassette has an opening through which said magnetic tape may be withdrawn to be loaded on said magnetic head assembly and a lid closing said opening when the cassette is not in use, and said apparatus further includes lid opening and closing means for opening and closing said lid in correspondence with the movement of said cassette holding means.
Claim 5
Dependent Claim
47 words
A magnetic recording and reproducing apparatus according to claim 2, further including an automatic eject means for moving said cassette holding means from said operative position to said eject position in correspondence with the movement of said movable section from said closed position to said open position.
Claim 6
Dependent Claim
74 words
A magnetic recording and reproducing apparatus according to claim 4, wherein said automatic eject means includes bias means for normally biasing said cassette holding means into said eject position; lock means for locking said cassette holder in said operative position against the biasing action of said bias means; and lock releasing means for releasing said lock means in accordance with the movement of said movable section from said closed position to said open position.
Claim 7
Dependent Claim
59 words
A magnetic recording and reproducing apparatus according to claim 1, wherein said movable section further includes tape loading means for withdrawing said magnetic tape from said tape cassette in said operative position and disposing the withdrawn tape in contact with said magnetic head assembly and for returning said magnetic tape from said magnetic head assembly to said tape cassette.
Claim 8
Dependent Claim
82 words
A magnetic recording and reproducing apparatus according to claim 6, wherein said movable section is moved from said open position to said closed position during a first period, and said tape loading means accomplishes said withdrawing and disposing of the magnetic tape entirely within said first period; and said movable section is moved from said closed position to said open position during a second period, and said tape loading means accomplishes said returning of the magnetic tape entirely within said second period.
Claim 9
Dependent Claim
69 words
A magnetic recording and reproducing apparatus according to claim 6, further comprising: first drive means for driving said movable section; second drive means for driving said tape loading means; and operation switch means for actuating said first drive means; said second drive means being actuated in response to at least a selected one of the operations of said first drive means, said movable section and said operation switch means.
Claim 10
Dependent Claim
45 words
A magnetic recording and reproducing apparatus according to claim 8, further including detector means for detecting the state and position of said tape loading means, and wherein operation of said second drive means is initiated and stopped in accordance with said detected state and position.
