    • A crank device which can produce a large torque without increasing the locus of the crank arm. The crank arm (6) has first (7) and second arms (8) which are longitudinally slidably coupled together through a pinion (13). The second arm is formed with two sets of rack teeth (17,18) on both sides of the pinion. The pinion has along its circumference a plurality of teeth (19) which are adapted to alternately come into mesh with the respective sets of rack teeth every time the crank arm makes a half turn in the same direction. Thus, the entire length of the crank arm alternately becomes maximum and minimum every time the crank arm turns by 180°. By applying a driving force to the crank arm when the length of the crank arm is maximum, it is possible to produce a large torque.
    • 一种不增加曲柄臂轨迹就能产生大转矩的曲柄装置。 曲柄臂(6)具有通过小齿轮(13)纵向可滑动地连接在一起的第一臂(7)和第二臂(8)。 第二臂在小齿轮的两侧形成有两组齿齿(17,18)。 小齿轮沿其圆周具有多个齿(19),每当曲柄臂在相同方向上转动半圈时,所述齿(19)适于交替地与各组齿条齿啮合。 因此,每当曲柄臂转动180°时,曲柄臂的整个长度交替变为最大值和最小值。 通过在曲柄臂的长度最大时对曲柄臂施加驱动力,可以产生大的转矩。

    • PROBLEM TO BE SOLVED: To provide a carry-in starting mechanism capable of carrying in a tray carried out to a disk replacement position by pressing it with small force in a disk device by which carry-in and carry-out are performed by engagement of a gear which is rotated and driven by a motor into a rack provided at a side part of the tray. SOLUTION: A boss 11 is provided at a rear end part of the rack 2 provided at a side part of the tray 1, a lacking tooth part is provided and a cam groove 12 is formed in the outer periphery of a gear to engage into the rack 2. The cam groove 12 is formed to have a size so that the boss 11 engages into the cam groove 12 when the tray 1 is carried out and the tray 1 moves backward by predetermined distance without rotation of a gear 4 when the tray 1 is carried in.
