Claims

[Scope of utility model registration request]

(1) A holding member that holds a pickup that emits an information reading light beam and is swingably supported on a predetermined substrate, and a driving means that drives the holding member to swing, and is capable of recording information. A crosstalk removal device for a recorded information reproducing apparatus, which removes crosstalk by adjusting the incident angle of the information reading light beam onto a medium by the driving means, A crosstalk removal device for a recorded information reproducing device, comprising: a rotating rotating member; and a detection means that operates at a rotational position of the rotating member corresponding to each limit position of an allowable swing range of the holding member. .

(2) The holding member and the driving means are connected by a positive cam, and the driving means has a bolt member that is threadedly engaged with the positive cam and interlocks with the rotating member. A crosstalk removal device for a recorded information reproducing device as claimed in claim 1.
