Abstract
Abstract A circuit substrate supporting structure for electronic components includes a circuit substrate, one side edge of which projects beyond a chassis of the component, a connector being mounted thereon from which a plug may be inserted or removed. The substrate projects from a lower base portion of the chassis. The connector is arranged on the projecting substrate, such that the engaging portion of the connector is faced away from the chassis. The chassis is covered with a shield case having a rear wall portion situated slightly above the upper surface of the connector such that the connector is between the substrate and the lower edge of the wall portion. The wall portion is formed with a stopper projecting from the lower edge in the vicinity of the connector for tightly retaining the connector between the stopper and the substrate to resist bending stress caused by the insertion and removal of the plug.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
184 words
A circuit substrate supporting structure for electronic apparatus including external connection means, comprising: a chassis; a circuit substrate member attached to said chassis such that an edge portion of said substrate protrudes outside of said chassis; a housing member, said housing member covering a portion of said chassis and having a face portion oriented perpendicular to said edge portion of said substrate and situated between a wall of the chassis contacting the substrate and the outer periphery of said edge portion such that a space exists between the bottom edge of said face portion and the surface of the substrate; a connector, said connector mounted on said protruding edge portion of said substrate in the space between the substrate surface and said bottom edge of said face portion such that a portion of said connector protrudes outside said space; a stopper member, associated with a lower area of said face portion, said stopper extending below said bottom edge of the face portion so as to contact said top surface of the connector thus securely holding said connector between the face portion and the substrate.
Claim 2
Dependent Claim
184 words
A circuit substrate supporting structure for electronic apparatus including external connection means, comprising: a chassis; a circuit substrate member attached to said chassis such that an edge portion of said substrate protrudes outside of said chassis; a housing member, said housing member covering a portion of said chassis and having a face portion oriented perpendicular to said edge portion of said substrate and situated between a wall of the chassis contacting the substrate and the outer periphery of said edge portion such that a space exists between the bottom edge of said face portion and the surface of the substrate; a connector, said connector mounted on said protruding edge portion of said substrate in the space between the substrate surface and said bottom edge of said face portion such that a portion of said connector protrudes outside said space; a stopper member, associated with a lower area of said face portion, said stopper extending below said bottom edge of the face portion so as to contact said top surface of the connector thus securely holding said connector between the face portion and the substrate.

Claim 9
Dependent Claim
221 words
A disc drive unit comprising: a chassis; a circuit substrate member attached to said chassis such that an edge portion of said substrate protrudes outside of said chassis; a housing member, said housing member having a planar top portion and two parallel planar side members of equal height and a rear wall portion oriented perpendicular to said edge portion of said substrate, said rear wall portion having a height which is less than that of said side members and situated between a wall of the chassis contacting the substrate and the outer periphery of said edge portion such that when a bottom edge of said side members are on a plane of said substrate a space exists between a bottom edge of said rear wall portion and the surface of the substrate; a connector, said connector mounted on said protruding edge portion of said substrate in the space between the substrate surface and said bottom edge of said rear wall portion such that a portion of said connector protrudes outside said space; a stopper member, associated with a lower area of said face portion, said stopper member extending below said bottom edge of the rear wall portion so as to firmly contact said top surface of the connector, thus securely holding said connector between the rear wall portion and the substrate.
Claim 10
Dependent Claim
221 words
A disc drive unit comprising: a chassis; a circuit substrate member attached to said chassis such that an edge portion of said substrate protrudes outside of said chassis; a housing member, said housing member having a planar top portion and two parallel planar side members of equal height and a rear wall portion oriented perpendicular to said edge portion of said substrate, said rear wall portion having a height which is less than that of said side members and situated between a wall of the chassis contacting the substrate and the outer periphery of said edge portion such that when a bottom edge of said side members are on a plane of said substrate a space exists between a bottom edge of said rear wall portion and the surface of the substrate; a connector, said connector mounted on said protruding edge portion of said substrate in the space between the substrate surface and said bottom edge of said rear wall portion such that a portion of said connector protrudes outside said space; a stopper member, associated with a lower area of said face portion, said stopper member extending below said bottom edge of the rear wall portion so as to firmly contact said top surface of the connector, thus securely holding said connector between the rear wall portion and the substrate.
