Abstract:
A recording/reproducing device operable in a recording/reproducing mode for receiving a recording medium for recording/reproducing purposes and an ejecting mode for ejecting said recording medium, said device comprising:a frame on which said device is arranged;a head carriage movably mounted on said frame and supporting a head for recording information onto said recording medium and reproducing information from said medium, said head carriage having an engagement portion;a locking member mounted on said frame and movable between a locking position at which said locking member engages said engagement portion of said head carriage to prevent movement of said bead carriage and an unlocking position at which said locking member is disengaged from said engagement portion to permit movement of said head carriage;a driving unit mounted on said frame for driving said locking member between it locking and unlocking positions;a substantially L-shaped first link member rotatably mounted on said frame, said first link member having a first end portion coupled to said driving unit and having a second end portion;a second link member mounted on said frame and having a first end portion coupled to said second end portion of said first link member and having a second end portion coupled to said locking member so that when said locking member is in said locking position, said second end portion of said first link member and said second link member are aligned in a straight line so as to be irreversibly prevented from movement if a shock is applied to said locking member, thereby preventing movement of said head carriage; anda force-applying member which applies force to said locking member to urge said locking member towards said locking position whereby when said recording medium is inserted into said device for recording/reproducing purposes, said device changes from its ejecting mode to its recording/reproducing mode in which said head carriage is released from said locking member to permit said head carriage to move and cause said head to approach said recording medium.
