Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
140 words
A cassette tape player comprising a chassis; a cassette holder to receive a cassette inserted from outside the chassis; an actuator arm pivotally disposed within the chassis and normally urged to rotate in a predetermined direction to counteract insertion of the cassette; a slide plate adapted for sliding movement to a predetermined position through a locking position in synchronized association with a rotation of the actuator arm in a direction opposite the predetermined direction; a hook plate normally urged to rotate away from said slide plate and adapted to engage the slide plate the moment the slide plate passes the locking position; and a cassette positioning lever pivotally provided in said chassis and adapted to initiate a rotation upon completion of said rotation of the actuator arm to perform a positioning operation of the cassette received in the cassette holder.
Claim 2
Dependent Claim
140 words
A cassette tape player comprising a chassis; a cassette holder to receive a cassette inserted from outside the chassis; an actuator arm pivotally disposed within the chassis and normally urged to rotate in a predetermined direction to counteract insertion of the cassette; a slide plate adapted for sliding movement to a predetermined position through a locking position in synchronized association with a rotation of the actuator arm in a direction opposite the predetermined direction; a hook plate normally urged to rotate away from said slide plate and adapted to engage the slide plate the moment the slide plate passes the locking position; and a cassette positioning lever pivotally provided in said chassis and adapted to initiate a rotation upon completion of said rotation of the actuator arm to perform a positioning operation of the cassette received in the cassette holder.
Claim 3
Dependent Claim
32 words
A cassette tape player according to claim 1, further including a push arm pivotally mounted on the actuator arm and normally urged to rotate in a direction opposite to said actuator arm.
Claim 4
Dependent Claim
41 words
A cassette tape player according to claim 2, wherein said push arm has a cut-out portion at its front end portion and said plate has a first pin and a roller provided coaxially therewith, said cut-out portion normally receiving said roller.
Claim 5
Dependent Claim
27 words
A cassette tape player according to claim 3, wherein said slide plate has a second pin and said hook plate is adapted to hook the second pin.
Claim 6
Dependent Claim
67 words
A cassette tape player according to claim 3, further including a pin rigidly fixed to the chassis, and said push arm has a slanting edge to abut against and ride up said pin when the push arm has pushed the slide plate to said predetermined position, thereby lifting the front end of the push arm to unlock the roller from the cut-out portion of the push arm.
Claim 7
Dependent Claim
20 words
A cassette tape player according to claim 1, wherein said cassette positioning lever is pivotally retained to the cassette holder.
Claim 8
Dependent Claim
74 words
A cassette tape player according to claim 6, wherein said cassette positioning lever has a roller attached thereto and said actuator arm has an arcuate surface concentric with the arm rotation, said roller being adapted to roll along the arcuate surface during the arm rotation, said surface having an extremity which passes said roller the moment the push arm pushes the slide plate past the locking position, whereby the said positioning operation is performed.
Claim 9
Dependent Claim
33 words
A cassette tape player according to claim 1, further including a cassette holding plunger connected to the hook plate and adapted to be energized the moment said slide plate passes the locking position.
Claim 10
Dependent Claim
20 words
A cassette tape player according to claim 8, further including means for absorbing a shock inflicted on the hook plate.
Claim 11
Dependent Claim
27 words
A cassette tape player according to claim 9, wherein said shock absorbing means includes a buffer rubber interposed between the cassette holding plunger and the hook plate.
