    摘要: In a record player, the movement of the tone arm is controlled by a select plate operated by a lever which moves the plate to a position corresponding to a record size. Adjacent the select plate is a C-shaped lever which cooperates with a rotary member. The rotary member has a plurality of cams which serve to program the operation and various movements of the tone arm. Extending from the peripheral edge of one of said cams is a brush. The tone arm is also responsive to a bracket with a wall, said wall being engaged by the brush. A position detector plate is mounted on the bracket which cooperates with a photo-interrupter to detect the position of the tone arm with respect to a record being played.

    摘要: A record player tonearm A may be swung about a shaft 3 and raised and lowered by an elevation plate 8 secured to a shaft 8a. The rounded lower end of shaft 8a serves as a follower on a cam 10 rotated about a shaft 9 by a planetary gear 13 mounted on a shaft 10b eccentrically disposed on the cam with respect to the shaft 9. The planetary gear is frictionally engaged with the cam 10 whereby it initially revolves about shaft 9 to thereby rotate the cam and raise or lower the tonearm. After approximately one-half of a revolution the planetary gear comes to frictionally abut against a sector plate 18 secured to the bottom of shaft 3. This terminates the revolution, whereafter the planetary gear rotates about its shaft 10b to drive the sector plate and swing the tonearm.

    摘要: The disclosure is directed to the mechanism for locating on, and reading out from, a flat disc record, by means of a pick-up needle, selected information which is recorded thereon. The overall controls for selecting and retrieving or reading out the desired parts of the recorded information, and for utilizing the information, are not a part of the present invention. The mechanism here disclosed and claimed is adapted to the performance, in sequence, of certain required mechanical operations and means for performing the same, some of which have utility in other fields such, for example, as record playing phonographs and the like.

    摘要: A tone arm, designed for use with a semi- or fully automatic record player, is provided with an electromagnetic drive mechanism. The tone arm is supported by two separate shafts so as to be rotatable in both the horizontal and vertical directions. A bobbin, to which horizontal and vertical drive coils are circumferentially attached, is arranged coaxially with that shaft permitting horizontal movement. A permanent magnet is arranged facing the drive coils. Interaction between the permanent magnetic field and those generated by energization of the drive coils causes either a torque or a vertical force to be imparted to the bobbin and thus effect a corresponding movement of the tone arm.
