Abstract
Abstract A magnetic disc device applicable to an electronic still camera system or a reproducer in an electronic camera system, wherein a subject is still-photographed pure-electronically and recorded into a rotating magnetic disc, and the reproduction of an image is carried out by a television, a printer or the like. A lid of this magnetic disc device is provided with a regulating plate at a position opposed to a magnetic head, for disposing the magnetic disc along the magnetic head. The regulating plate is finely movably provided on the lid, and attracted and fixed by magnets, when the lid is closed, whereby, even if the regulating plate is finely movably provided such that the regulating plate can be positioned at a predetermined position, the regulating plate can be held unmovably at the time of the reproduction of the magnetic record when the lid is closed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
166 words
A rotary magnetic disc device comprising: a main body of device wherein a rotary driving source and a magnetic head are provided; a lid openably supported on the main body of device; supporting means for pivotally supporting said lid on said main body; a regulating plate movably provided on said lid and located at a position opposed to said magnetic head, when said lid is closed, to dispose a magnetic disc along said magnetic head; mounting means for movably mounting said regulating plate on said lid; a plurality of magnets located on one of said main body of the device and said regulating plate; a plurality of magnetic materials provided on the other one of said main body of the device and said regulating plate, for attracting and fixing the regulating plate to the main body of the device when the lid is closed; and positioning means for positioning the regulating plate at a predetermined position relative to said magnetic head when the lid is closed.
Claim 2
Dependent Claim
166 words
A rotary magnetic disc device comprising: a main body of device wherein a rotary driving source and a magnetic head are provided; a lid openably supported on the main body of device; supporting means for pivotally supporting said lid on said main body; a regulating plate movably provided on said lid and located at a position opposed to said magnetic head, when said lid is closed, to dispose a magnetic disc along said magnetic head; mounting means for movably mounting said regulating plate on said lid; a plurality of magnets located on one of said main body of the device and said regulating plate; a plurality of magnetic materials provided on the other one of said main body of the device and said regulating plate, for attracting and fixing the regulating plate to the main body of the device when the lid is closed; and positioning means for positioning the regulating plate at a predetermined position relative to said magnetic head when the lid is closed.
Claim 3
Dependent Claim
34 words
A rotary magnetic disc device as set forth in claim 1, wherein said supporting means comprises pins, which are loosely coupled into holes of the regulating plate, to thereby movably support the regulating plate.
Claim 4
Dependent Claim
57 words
A rotary magnetic disc device as set forth in claim 2, wherein said positioning means comprises at least two balls for positioning, which are provided on either one of the main body of device and the regulating plate, and a tapered hole and a tapered groove capable of receiving said balls, which are provided on the other.
Claim 5
Dependent Claim
34 words
A rotary magnetic disc device as set forth in claim 3, wherein said tapered groove is formed into a generally V-shape in cross section and disposed in the moving direction of said magnetic head.
