Abstract
Abstract An arrangement for supporting one or more circuit boards within an electronic equipment housing including a first rigidly supporting member and a second loosely supporting member. The second loosely supporting member includes a base plate and a biasing member. The biasing member is disposed between the housing and the base plate or between the base plate and slot members, or both, in such a manner that it biases the slot members towards the first rigidly supporting member. The slot members are thereby biased to loosely hold the loose ends of the circuit boards, and thus, the circuit boards, which are disposed between the first rigidly supporting member and the second loosely supporting member, are prevented from sliding out of the slot members, even when the loose ends of the circuit boards move relative to the housing due to shocks and vibration during transportation or handling.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
132 words
An arrangement for supporting at least one circuit board within an electronic equipment housing comprising; first support means disposed in the housing for rigidly supporting a first end of the circuit board on the housing; and second support means disposed in the housing opposite to said first support means for slidably receiving therein and elastically supporting a second end of the circuit board, wherein said second support means comprises a slot member having a slot for slidably receiving therein said second end of the circuit board and a biasing member disposed beween said slot member and the housing for biasing said slot member toward said first support means, thereby allowing said second support means to follow the second end when the second end of the circuit board moves relative to said housing.
Claim 2
Dependent Claim
132 words
An arrangement for supporting at least one circuit board within an electronic equipment housing comprising; first support means disposed in the housing for rigidly supporting a first end of the circuit board on the housing; and second support means disposed in the housing opposite to said first support means for slidably receiving therein and elastically supporting a second end of the circuit board, wherein said second support means comprises a slot member having a slot for slidably receiving therein said second end of the circuit board and a biasing member disposed beween said slot member and the housing for biasing said slot member toward said first support means, thereby allowing said second support means to follow the second end when the second end of the circuit board moves relative to said housing.
Claim 3
Dependent Claim
39 words
An arrangement for supporting a circuit board as claimed in claim 1 wherein said second support means further comprises a base plate attached to the housing, said biasing member being mounted between said base plate and said slot member.
Claim 4
Dependent Claim
24 words
An arrangement for supporting a circuit board as claimed in claim 2 wherein said second support means comprises a plurality of said slot members.
Claim 5
Dependent Claim
28 words
An arrangement for supporting a circuit board as claimed in claim 3 wherein said second support means is an integrally moulded member made of an elastic plastic material.
Claim 6
Dependent Claim
34 words
An arrangement for supporting a circuit board as claimed in claim 1 wherein said second support means further comprises a base plate, said biasing member being mounted between said housing and said base plate.
Claim 7
Dependent Claim
29 words
An arrangement for supporting a circuit board as claimed in claim 5 wherein said second support means comprises a plurality of said slot members supported by said base plate.
Claim 8
Dependent Claim
40 words
An arrangement for supporting a circuit board as claimed in claim 6 wherein said biasing member is an elongated elastic member having one end attached to said base plate and having the other end thereof in contact with said housing.
Claim 9
Dependent Claim
39 words
An arrangement for supporting a circuit board as claimed in claim 6 wherein said biasing member is an elongaged elastic member having one end attached to said housing and having the other end in contact with said base plate.
Claim 10
Dependent Claim
47 words
An arrangement for supporting a circuit board as claimed in claim 1 wherein said second support means further comprises a base plate attached to the housing, said biasing member being mounted between said base plate and said slot member and between said housing and said base plate.
