Abstract
A portable device having compact size while accommodating a mechanical key therein. The mechanical key has an opening and an internal space, which are in communication with each other. An engagement member, arranged in the internal space, is movable between a first position where it partially projects from the opening and a second position where it is accommodated in the internal space. A resilient member, which urges the engagement member from the second position toward the first position is arranged in the internal space, includes a fixing portion fixed to the mechanical key in the internal space. The portable device further includes a case having a key accommodation portion for removably accommodating the mechanical key. The key accommodation portion includes an engaged portion that is engaged with the engagement member when the mechanical key is accommodated in the key accommodation portion.

12. A method for assembling a mechanical key for arrangement in a case of a portable device for electronically locking and unlocking a lock through wireless communication in which the mechanical key is for mechanically locking and unlocking the lock, wherein the case includes a key accommodation portion for removably accommodating the mechanical key, the method comprising:
-
arranging an engagement member, which is engageable with an engaged portion formed in the key accommodation portion, in an internal space formed in a main body of the mechanical key, in which the internal space is in communication with an opening formed in the mechanical key, and the engagement member is movable between a first position at which part of the engagement member projects from the opening and engages with the engaged portion and a second position at which the engagement member is substantially accommodated in the mechanical key;
fixing a fixing portion arranged on a coil spring, which urges the engagement member from the second position toward the first position, to an inner surface of a cover defining the internal space; and
attaching the cover, to which the coil spring is fixed, to the main body of the mechanical key with the coil spring held between the cover and the engagement member. - View Dependent Claims (13)
