Title: Mounting device
Inventor: AEBA KOJI
IPC: H05K7/12
Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To absorb any strain to be transmitted to a chassis, and also to make a lower cover surely connectible to it by installing a notch in and around a part, where this lower cover is contacted with the chassis, forming a lower cover support part, and supporting it elastically on the chassis. SOLUTION: When a lower cover 6 is attached to a chassis 32, those of chassis 32 and lower cover 6 are superposed on the specified position, and then a lower cover mounting screw 27 is inserted from the side of a lower cover mounting insertional hole 22 and it is screwed in a lower cover mounting tapped hole 24. At this time, a notch 25 is installed in and around this tapped hole 24, forming a lower cover support part 26, and the lower cover mounting tapped hole 24 is elastically supported by the chassis 32. With this constitution, any strain to be produced in the lower cover 6 is absorbed, so the strain of the chassis is thus relievable.  In addition, in the case where the lower cover 6 has the strain as a simple as well as in the case where there is the strain being produced by reason that the lower cover mounting tapped hole 24 of the chassis 32 is shifted out of the specified position, the strain of the lower cover 6 is absorbed, and the strain of the chassis 32 is also relievable likewise.
