Abstract
Abstract A cassette eject mechanism for a recording or reproducing apparatus can remove a cassette eject button from a housing and can reliably eject a tape cassette only when a tape cassette should be loaded or unloaded. A battery loading mechanism for an electronic equipment can make the loading of battery simple and reliable, and becomes easy to handle. The locking mechanism can be simplified in structure so that the number of assembly parts can considerably be reduced. Further, a mechanical chassis supporting mechanism in a recording apparatus is for use with an apparatus in which a mechanical chassis or cabinet can be reduced in thickness. According to this mechanical chassis supporting mechanism, it is possible to prevent an external stress from being applied to the mechanical chassis as a twisting deform force.
