Music box movement with detent stop

摘要

A movement for a musical box comprising a base plate (11) supporting a roller (13) which has a plurality of radial pins (14) arranged to actuate a plurality of reeds (15) of a musical keyboard (16). The roller (13) is driven by a drive mechanism (12) via a movement train (17). A detent stop (18) is provided for preventing, as desired, movement of the roller. The detent stop has a support which is either force fitted or resiliently attached to the music box without disturbing the alignment between the musical keyboard and the roller.
