Claims (1)

[Scope of claim for utility model registration] (1) In a disc information reproducing device that extracts information signals from an information recording disc and reproduces images or sounds, the only disc that rotates two types of information recording discs at different speeds. A motor, a different type of pickup section provided for each information recording disk, and an electric circuit that processes information signals extracted from the two types of information recording disks and controls the disk motor. Disc information reproducing device featuring features. (2) The electric circuit includes a pulse generation circuit that notifies that one or the other of the two types of information recording disks is installed, and a pulse from this pulse generation circuit that drives the first disk motor via the servo circuit. Alternatively, a request for registration of a utility model characterized by comprising a system control circuit that rotates at a second speed and a signal processing circuit that processes information signals extracted from the information recording disk and reproduces images or sounds.
