Abstract
Abstract A printed circuit board mounted in a casing together with other electronic and/or electric devices in a compact and spacing-saving manner, thereby enabling provision of a compact and small-sized casing. The printed circuit board is detachably mounted through pairs of first and second guide members on a flat mounting surface of the casing with at least one electric device disposed in and attached to the casing perpendicularly spaced from the flat mounting surface in a manner such that the printed circuit board is slidable parallel to the flat mounting surface of the casing underneath the electronic and/or electric devices to a mounted position for removal and mounting of the printed circuit board.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
201 words
In combination, a printed circuit board; a casing having a flat mounting surface for said printed circuit board and at least one electrical device disposed in and attached to said casing at a location perpendicularly spacd from and above the mounting surface and an opening adjacent the mounting surface; and means for guiding said circuit board through the opening and parallel to the flat mounting surface of said casing to a mounted position underneath said electrical device and for detachably mounting said printed circuit board in said casing in the mounted position; said means for guiding and detachably mounting said mounted circuit board comprising: first guide means including a pair of first guide members fixedly disposed on the flat mounting surface of said casing in a spaced parallel relation with each other; and second guide means having a pair of second guide members formed separately from said printed circuit board and detachably secured thereto by fastening means in a spaced parallel relation with each other so as to be slidably engageable with said first guide members for guiding said printed circuit board through the opening in said casing to the mounted position for removal and mounting of said printed circuit board.
Claim 2
Dependent Claim
201 words
In combination, a printed circuit board; a casing having a flat mounting surface for said printed circuit board and at least one electrical device disposed in and attached to said casing at a location perpendicularly spacd from and above the mounting surface and an opening adjacent the mounting surface; and means for guiding said circuit board through the opening and parallel to the flat mounting surface of said casing to a mounted position underneath said electrical device and for detachably mounting said printed circuit board in said casing in the mounted position; said means for guiding and detachably mounting said mounted circuit board comprising: first guide means including a pair of first guide members fixedly disposed on the flat mounting surface of said casing in a spaced parallel relation with each other; and second guide means having a pair of second guide members formed separately from said printed circuit board and detachably secured thereto by fastening means in a spaced parallel relation with each other so as to be slidably engageable with said first guide members for guiding said printed circuit board through the opening in said casing to the mounted position for removal and mounting of said printed circuit board.
Claim 3
Dependent Claim
60 words
The combination of claim 1, said first guide members having an inverted L-shaped cross section and being fixedly secured to the flat mounting surface in a spaced parallel relation with each other and having flanges, said second guide members cooperating with said flanges of said first guide members for slidably guiding said printed circuit board for removal and mounting thereof.
Claim 4
Dependent Claim
55 words
The combination of claim 1, said first guide members comprising continuous members fixedly secured to the flat mounting surface in a spaced parallel relation with each other and having flanges, said second guide members cooperating with said flanges of said first guide members for slidably guiding said printed circuit board for removal and mounting thereof.
Claim 5
Dependent Claim
47 words
The combination of claim 1, said first guide members having flanges spaced perpendicularly from and extending parallel to the mounting surface, and said second guide members cooperating with said flanges of said first guide members for slidably guiding said printed circuit board for removal and mounting thereof.
Claim 6
Dependent Claim
55 words
The combination of claim 1, said first guide members comprising discontinuous members fixedly secured to the flat mounting surface in a spaced parallel relation with each other and having flanges, said second guide members cooperating with said flanges of said first guide members for slidably guiding said printed circuit board for removal and mounting thereof.
Claim 7
Dependent Claim
55 words
The combination of claim 1, said first guide members having a channel-shaped cross section and being fixedly secured to the flat mounting surface in a spaced parallel relation with each other, and said second guide members cooperating with said channel-shaped first guide members for slidably guiding said printed circuit board for removal and mounting thereof.
Claim 8
Dependent Claim
53 words
The combination of claim 1, said second guide members having an inverted Z-shaped cross section and being secured to the printed circuit board in a spaced parallel relation with each other, said second guide members cooperating with said first guide members for slidably guiding said printed circuit board for removal and mounting thereof.
