    • 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.

    • PURPOSE:To permit the steering gear ratio to be expanded by a large amount by forming a pinion into the cylindrical gear having a specific engagement pitch curve symmetrical in right and left and forming a rack into a specific tooth form. CONSTITUTION:In the steering gear apparatus equipped with the pinion 4 engaged with a handle operating shaft and the rack 7 which is shifted in the longitudinal direction through the revolution of the pinion 4, the pinion 4 is formed in the cylindrical gear having a plurality of teeth 4a, and the center of the addendum circle 4b is allowed to coincide with the center O of revolution of the pinion 4. As shown by the engagement pitch curve 4c of the pinion 4, the diameter rp of the pitch circle becomes the max. at the neutral position of the pinion 4, and decreases gradually with the revolution of the pinion 4, and becomes the minimum at 180 deg. revolution. While, the rack 7 is formed so as to form positive profile shifted tooth form B in the vicinity of the neutral position, the standard rack tooth form C in the vicinity of steering angle 180 deg., and the negative profile shifted tooth form A in the vicinity of steering angle 360 deg..
    • 目的:通过将小齿轮形成为具有左右对称的特定接合间距曲线的圆柱齿轮,使转向齿轮比大幅度扩大,并将齿条形成为特定齿形。 构成:在配备有与手柄操作轴接合的小齿轮4的转向齿轮装置和通过小齿轮4的旋转沿长度方向移位的齿条7上,小齿轮4形成在具有多个 齿4a,并且齿数圆4b的中心与小齿轮4的转动中心O重合。如小齿轮4的啮合节距曲线4c所示,节圆的直径rp变为最大。 在小齿轮4的中立位置处,随着小齿轮4的旋转而逐渐减小,并且在180度处变为最小。 革命。 而齿条7形成为在中立位置附近形成正轮廓偏移齿形B,在转向角180度附近形成标准齿条齿形C,将负轮廓偏移齿形A 转向角360度附近
