Abstract

Stop pin 10 (Fig. 1) cooperates with radially extending pins 12 and 14, fixed on swingable actuator 16, for limiting the swinging movement of actuator 16. Pin 10 is designed so that stopping the rotation of actuator 16 is cushioned. Actuator 16 is swingably mounted in plate 18, and may, for example, support magnetic heads that swing across a magnetic disk in a disk file assembly. Pin 10 is eccentrically mounted in sleeve 20 (Fig. 2), and sleeve 20 is provided with external screw threads 20A by means of which it is rotatably mounted in plate 18. Sleeve 20 is provided with a hexagonal slot 20B in its lower end. (Image Omitted) Pin 10 is mounted at its lower end in sleeve 20 so that there is an annular gap 22 between pin 10 and the inner surface of sleeve 20 for most of the length of pin 10, imparting flexibility to pin 10.

Pin 10 is mounted at its lower end in sleeve 20 so that there is an annular gap 22 between pin 10 and the inner surface of sleeve 20 for most of the length of pin 10, imparting flexibility to pin 10. Sleeve 20 is rotatable in plate 18 using an Allen wrench fitting in hexagonal slot 20B for adjusting the rotative position of sleeve 20 in plate 18, and lock nut 24 is tightened on the end of sleeve 20 and against the bottom face of plate 18 once sleeve 20 has been rotatably adjusted in position in plate 18 for holding sleeve 20 in an adjusted position. The position of pin 10 due to its eccentric mounting in sleeve 20 may be adjusted circumferentially of the longitudinal center of actuator 16 adjusting the rotative position of sleeve 20 in plate 18 after lock nut 24 has been released so as to adjust the rotative positions at wh...
