摘要 |
A spindle-height gage is provided for measuring the height of one or more spindles in a tape recorder. The gage includes a pair of indicators rigidly mounted to a stable base configured for insertion into the tape recorder in lieu of a cassette. Upon insertion of the base plate into the recorder, the spindle under test comes into contact with a "foot" extending from a shaft of one of the indicators, which then provides indication of the spindle height. The gage is calibrated by inserting into the gage a calibrating disc having two shoulders, each of a height corresponding to the specified height of one of the spindles. |
