Abstract
Abstract An electronic apparatus is comprised of a main board 1 having a main-circuit mounting region 6 and an oscillating-circuit mounting region 2; a shielding case 5 for covering the oscillating-circuit mounting region by being attached to the main board; a sub-board 10 on which circuit components 3 and 4 constituting an oscillating circuit portion 11 are mounted and which is supported at a position spaced part from the main board inside the shielding case; and a connector 12 for electrically connecting the sub-board and the main board.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
112 words
An electronic apparatus comprising: a main board having a main-circuit mounting region and an oscillating-circuit mounting region; a shielding case for covering said oscillating-circuit mounting region by being attached to said main board, said shielding case having a pair of cutout portions formed in opposing sidewalls thereof; a sub-board on which circuit components including an oscillating circuit portion are mounted, said sub-board having a pair of projecting portions corresponding to the cutout portions, whereby said sub-board is supported at a position spaced apart from said main board inside said shielding case by fitting the projecting portions into the cutout portions; and a connector for electrically connecting said sub-board and said main board.
Claim 2
Dependent Claim
112 words
An electronic apparatus comprising: a main board having a main-circuit mounting region and an oscillating-circuit mounting region; a shielding case for covering said oscillating-circuit mounting region by being attached to said main board, said shielding case having a pair of cutout portions formed in opposing sidewalls thereof; a sub-board on which circuit components including an oscillating circuit portion are mounted, said sub-board having a pair of projecting portions corresponding to the cutout portions, whereby said sub-board is supported at a position spaced apart from said main board inside said shielding case by fitting the projecting portions into the cutout portions; and a connector for electrically connecting said sub-board and said main board.
