Abstract
Abstract A magnetic recording and/or reproducing apparatus has a rotary drum unit (3, 4) co-operating with a magnetic head or magnetic heads for recording or reproducing signals on or from magnetic tape A loading device (17, 17) is movable between a first position and a second position by the operation of a single electric motor (16), a tape guide device (7, 8, 7, 8) is responsive to movement of the loading device (17,17) so as to extract and guide the tape by being moved between an inoperative position and an operative position in which a preset tape path is defined in proximity to the drum device (3; 4), and a pinch roller operating device (31, 39,14) is also operated by the loading device (17, 17) for pressing a pinch roller (11) against a capstan (10) or disengaging the pinch roller (11) from the capstan (10).

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
252 words
Magnetic recording and/or reproducing apparatus comprising (a) a rotary drum unit (3, 4) having a magnetic head or magnetic heads for signal recording or reproducing on or from magnetic tape (5); (b) an electric motor (16); (c) loading means (6, 17, 6, 17) movable between a first position and a second position upon operation of the electric motor (16); characterised by (d) tape guide means (7, 8) engaging with the loading means (6, 17, 6, 17) and, responsive to movement of the loading means (6, 17, 6, 17) from said first position to said second position, extracting and guiding the magnetic tape as the tape guide means (7, 8) are moved from an inoperative position inside a tape cassette to an operative position in which they define a preset tape path adjacent the drum unit (3, 4); (e) a capstan (10) to rotate at a constant speed; (f) means (14) supporting a pinch roller (11) and movable between a position in which the pinch roller (11) is pressed against the capstan (10) and a position in which the pinch roller (11) is disengaged from the capstan (10); and (g) pinch roller actuating means (31, 39) mounted on the loading means and engageable with the pinch roller supporting means (14); (h) wherein the electric motor (16) is actuated for. shifting the loading means (6, 17, 6, 17) and also the pinch roller actuating means (31, 39) for controlling the movement of the pinch roller supporting means (14) between said pressing and disengaging positions.
Claim 2
Dependent Claim
252 words
Magnetic recording and/or reproducing apparatus comprising (a) a rotary drum unit (3, 4) having a magnetic head or magnetic heads for signal recording or reproducing on or from magnetic tape (5); (b) an electric motor (16); (c) loading means (6, 17, 6, 17) movable between a first position and a second position upon operation of the electric motor (16); characterised by (d) tape guide means (7, 8) engaging with the loading means (6, 17, 6, 17) and, responsive to movement of the loading means (6, 17, 6, 17) from said first position to said second position, extracting and guiding the magnetic tape as the tape guide means (7, 8) are moved from an inoperative position inside a tape cassette to an operative position in which they define a preset tape path adjacent the drum unit (3, 4); (e) a capstan (10) to rotate at a constant speed; (f) means (14) supporting a pinch roller (11) and movable between a position in which the pinch roller (11) is pressed against the capstan (10) and a position in which the pinch roller (11) is disengaged from the capstan (10); and (g) pinch roller actuating means (31, 39) mounted on the loading means and engageable with the pinch roller supporting means (14); (h) wherein the electric motor (16) is actuated for. shifting the loading means (6, 17, 6, 17) and also the pinch roller actuating means (31, 39) for controlling the movement of the pinch roller supporting means (14) between said pressing and disengaging positions.
Claim 3
Dependent Claim
79 words
Magnetic recording and/or reproducing apparatus according to claim 1, wherein said operative position of said tape guide means (7, 8) defining said preset tape path includes a third position between said first and second positions, and wherein, with said tape guide means (7, 8) set to said operative position, only said loading means is shifted between said second and third positions for controlling the operation of the pinch roller through the intermediary of the pinch roller supporting means (14).
Claim 4
Dependent Claim
28 words
Magnetic recording and/or reproducing apparatus according to claim 1, wherein the loading means includes at least one rotary member in the form of a rotatably supported ring (17).
Claim 5
Dependent Claim
35 words
Magnetic recording and/or reproducing apparatus according to any one of claims 1 to 3, wherein the loading means includes two rotary members (17, 17) supported in superposed relation and movable in opposite directions of rotation.
Claim 6
Dependent Claim
31 words
Magnetic recording and/or reproducing apparatus according to any one of claims 1 to 4, wherein the tape guide means comprises deflection guide members (8, 8) and inclined guide members (7, 7).
Claim 7
Dependent Claim
