    • A moving-coil type pickup cartridge comprising a cantilever provided at the free end thereof with a stylus for tracing a sound groove of a record disc, a coil plate provided on the cantilever in a manner to vibrate in response to vibration of the stylus, and an arrangement for producing an effective magnetic field within a specific gap. The coil plate comprises a thin electrically insulating base plate and at least one coil which is formed from a thin film in a spirally-shaped pattern on at least one surface of the base plate. The coil plate has at least one upright part formed by bending the base plate together with a portion of the coil and interposed in a freely vibratory manner within said gap of the magnetic field producing arrangement and a mounting part integrally joined to the upright part and fixed to the cantilever.

    • A signal pickup device in a rotary recording medium reproducing apparatus, comprises a cantilever provided with a reproducing element for picking up and reproducing a signal from a rotary recording medium at the tip end thereof, a support member having a support part for supporting the rear end part of the cantilever, and arms which unitarily extend on both sides from the support part, and a frame having engaging parts engaged with and mounted with the arms of the support member, for holding the arms. The arms of the support member respectively are provided with mounting parts having non-circular cross-section in the vicinity of the end part thereof, for engaging with the engaging parts of the frame. Moreover, the mounting parts and the engaging parts are shaped so that the support member is at an angular position together with the cantilever where the reproducing element is at a raised position, when the mounting parts are mounted onto the engaging parts.
    • 一种旋转记录介质再现装置中的信号拾取装置,包括悬臂,其具有用于拾取和再现来自其顶端的旋转记录介质的信号的再现元件;支撑构件,具有用于支撑后端 悬臂的一部分和从支撑部分两侧一体地延伸的臂,以及具有与支撑构件的臂接合并与其一起安装的用于保持臂的框架。 支撑构件的臂分别在其端部附近设置有具有非圆形横截面的安装部分,用于与框架的接合部分接合。 此外,当将安装部件安装到接合部件上时,安装部件和接合部件被成形为使得支撑部件与再现元件处于升高位置的悬臂一起处于角位置。
