Title:
MAGNETIC CLUTCH HOUSING AND MAGNETIC CLUTCH
Document Type and Number:
Japanese Patent JPS5729825
Kind Code:
A
Abstract:
A rotatable housing for a magnetic clutch contains a circumferential mounting portion thereon for receiving a rotary member, as, for example, a spool of recording tape. The mounting portion defines a surface therearound which contains detents for axially locating the rotary member on the latter surface. In a preferred embodiment, the detents are arranged in clusters about the circumference of the mounting surface, each cluster including at least two detents axially spaced, each detent defining a circumferentially extending protuberance on the mounting surface. In an alternate preferred embodiment, the mounting surface also includes a drive tang for limiting movement of the rotary member to one direction only, the drive tang defining an axially extending protuberance on the mounting surface.
