Abstract
A recording and/or reproducing apparatus using a magnetic disc housed in a cassette, in which the cassette is received and placed by a cassette holder at a predetermined loading position for the signal recording and/or reproduction where a magnetic head is provided. The head is moved relative to the disc by a head moving mechanism driven by a motor, while the holder is moved by a loading mechanism which is selectively connectible with the motor through a clutch mechanism. Thus, the head moving motor is also utilized as a cassette loading motor.
Claims8
A recording and/or reproducing apparatus comprising:
- a holder movable between a first position for receiving a record bearing medium and a second position for placing the received medium at a predetermined loading position;
- a recording and/or reproducing head;
- a head moving mechanism for moving said head relative to the medium to change the recording or reproducing position on the medium;
- a drive source for said head moving mechanism;
- a loading mechanism for moving said holder between said first and second positions;
- and
- clutch means for selectively connecting said loading mechanism with said driving source;
- said loading mechanism including at least one movable member which is movable in a first direction for moving said holder from said first to said second positions and in a second direction, opposite to said first direction, for moving the holder from said second to said first positions, said clutch means being arranged to selectively connect said movable member with said driving source;
- said clutch means including a pinion gear connected with said driving source, a rack member operatively connected with said movable member in said loading mechanism, said rack member having a first and a second rack portions and being arranged to move the movable member in said first direction when engaged with said pinion gear at said first rack portion and to move the movable member in said second direction when engaged with the pinion gear at said second rack portion, and control means for engaging said rack member with said pinion gear at said first and second rack portions selectively and for retaining the rack member at a disengaged condition relative to the pinion gear.

A recording and/or reproducing apparatus using a disc-shaped record bearing medium housed in a container which is provided with an opening, said apparatus comprising:
- a holder movable between a first position for receiving the container and a second position for placing the received container at a predetermined loading position;
- a recording and/or reproducing head arranged to face with the medium through the opening of the container placed at said predetermined loading position;
- rotating means for rotating the medium relative to said head;
- a head moving mechanism for moving said head relative to the medium to change the recording or reproducing position on the medium;
- a driving source for said head moving mechanism;
- a loading mechanism for movign said holder between said first and second positions;
- and
- clutch means for selectively connecting said loading mechanism with said driving source;
- said loading mechanism including at least one movable member which is movable in a first direction for moving said holder from said first to said second positions and in a second direction, opposite to said first direction, for moving the holder from said second to said first positions, said clutch means being arranged to selectively connect said movable member with said driving source,
- said clutch means including a pinion gear connected with said driving source, a rack member operatively connected with said movable member in said loading mechanism, said rack member having a first and a second rack portions and being arranged to move the movable member in said first direction when engaged with said pinion gear at said first rack portion and to move the movable member in said second direction when engaged with the pinion gear at said second rack portion, and control means for engaging said rack member with said pinion gear at said first and second rack portions selectively and for retaining the rack member at a disengaged condition relative to the pinion gear.
