    • Capstan drive arrangement for high speed intermittent tape drive, including a motor driven capstan, an idler roller carried on a lever arm, and an electromagnet selectively operable to pivot the level about its axis to urge the idler roller towards the capstan to produce a tape driving pinch. The level arm is arranged so that when the electromagnet is not operated, the idler roller contacts the tape with substantially negligible pressure. The drive arrangement also includes a damping system having an elastically deformable connection between the lever arm and a rod having a side surface held in contact with a fixed abutment by a pusher.
    • 用于高速间歇磁带驱动器的绞盘驱动装置,包括马达驱动的绞盘,承载在杠杆臂上的惰轮,以及电磁铁,其可选择性地可操作以围绕其轴线枢转水平以将惰轮推向主导轴以产生磁带驱动 捏。 水平臂布置成使得当电磁体不被操作时,惰辊以大致可忽略的压力接触带。 驱动装置还包括阻尼系统,该阻尼系统在杠杆臂和杆之间具有可弹性变形的连接,杆的侧面通过推动器与固定的支座保持接触。
