Patent ID: 8363395

Claim:
A release mechanism for an electronic device adapted to detachably house an electronic device unit, comprising: a guide body adapted to slidably support a guide wall of the electronic device unit; and a locking mechanism adapted to lock the electronic device unit supported on the guide body; wherein the locking mechanism includes (i) an elastic piece projecting in cantilever fashion from an end of the guide body, (ii) an operating projection that projects from the elastic piece, and (iii) an engaging protrusion that protrudes from the elastic piece and that is adapted to intrude into a screw hole of the electronic device unit to thereby restrict sliding of the electronic device unit; and the operating projection is formed with larger size than the engaging protrusion so that the engaging protrusion disengages from the screw hole and then the electronic device unit slides on the guide body without the engaging protrusion contacting with the guide wall of the electronic device unit, when under inducing flexure of the elastic piece, external force is applied to the electronic device unit in a sliding direction.
