Apparatus for insertion of a key therein

摘要

An apparatus for insertion of a key (28) therein substantially prevents foreign matter from entering into a key insertion hole (22), and even if foreign matter does enter into the key insertion hole (22), discharges the foreign matter therefrom. A shutter (30) is provided within the key insertion hole (22) so as to be movable along a direction of insertion of a key (28). The shutter (30) is always urged by a compression coil spring (40) toward an opening (24) of the insertion hole (22). In a state in which no key (28) is inserted, the shutter (30) closes the insertion hole (22). The shutter (30) is provided with a reflecting surface (38), and when no key (28) is inserted in the insertion hole (22), the reflecting surface (38) reflects light from a light source (36) so as to illuminate the opening (24) of the insertion hole (22). Thus, even if a region surrounding the opening (24) of the insertion hole (22) is dark, the opening (24) can be visually confirmed and the key (28) can be easily inserted into the insertion hole (22).
