ABSTRACT:
The present invention relates to an apparatus for connecting a transmission device to an optical pick-up. The transmission device includes a connecting unit and a lead screw and a driving unit. The connecting unit includes a main portion, an elastic portion, a tooth-like portion and a restriction portion. The restriction portion limits the elastic portion to move within a range of a first value. The lead screw engages with the tooth-like portion. A maximum engagement depth between the lead screw and the tooth-like portion is a second value. The second value is larger than the first value to prevent the lead screw and the tooth-like portion from disengaging.
