Mounting for an optical sensor has sensor inserted into recess in a formed carrier and latched into position

摘要

The end of a magnetic tape used in a recorder/player is sensed by passing light from an LED through the transparent end section to a sensor. The photo optic sensor fits into an aperture (61 b) in a plastic carrier (61). The carrier has formed ends for mounting onto a base. The top section (62) folds over and latches to retain the sensor.
