Abstract

Abstract A linear motor (3) is movably disposed in a disc unit (1) internally provided with a loading device (11) for loading and ejecting a disc cartridge (10) and is securely locked by a locking mechanism at the time of ejection of the cartridge (10). The locking mechanism comprises a first locking member (12) extending downwards from the loading device (11) and a second locking member (9) securely mounted on the linear motor (3). When the disc cartridge (10) is ejected by the loading device (11), the first locking member (12) is brought into contact with the second locking member (9) to move the linear motor (3) towards a location at which the linear motor (3) is securely locked.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 104 words
A mechanism for locking a linear motor (3) movably disposed in a disc unit (1) which is internally provided with a loading device (11) for loading and ejecting a disc cartridge (10), said mechanism comprising: a first locking member (12) extending downwards from the loading device (11); and a second locking member (9) securely mounted on the linear motor (3); said first locking member (12), when the disc cartridge (10) is ejected by the loading device (11), being brought into contact with said second locking member (9) to move the linear motor (3) towards a location at which the linear motor (3) is locked.
Claim 2
Dependent Claim 104 words
A mechanism for locking a linear motor (3) movably disposed in a disc unit (1) which is internally provided with a loading device (11) for loading and ejecting a disc cartridge (10), said mechanism comprising: a first locking member (12) extending downwards from the loading device (11); and a second locking member (9) securely mounted on the linear motor (3); said first locking member (12), when the disc cartridge (10) is ejected by the loading device (11), being brought into contact with said second locking member (9) to move the linear motor (3) towards a location at which the linear motor (3) is locked.
Claim 3
Dependent Claim 50 words
The mechanism according to claim 1, wherein a portion of said linear motor (3) is sandwiched between a frame (4) fixedly mounted in the disc unit (1) and said first locking member (12) in contact with said second member (9), when said linear motor (3) is locked at said location.
Claim 4
Dependent Claim 60 words
A disc unit including a linear motor (3) for driving a head (7) of the unit and a loading device (11) for loading and ejecting a disc member (10) to and from the unit, characterised in that said loading unit is arranged to move a moveable component of the linear motor to a locked position when it ejects the disc.
Claim 5
Dependent Claim 60 words
A disc unit including a linear motor (3) for driving a head (7) of the unit and a loading device (11) for loading and ejecting a disc member (10) to and from the unit, characterised in that said loading unit is arranged to move a moveable component of the linear motor to a locked position when it ejects the disc.
