Abstract
An oscillatory drive mechanism for a member to be driven comprises a flexural element (12) having a first portion (14) rigidly attached to a datum with respect to which the member is to be driven, and a second portion (15) rigidly attached to the member, the first and second portions (14,15) being interconnected by one or more first interconnecting members (17) which in the main determine the spring characteristics of the flexural element (12), and one or more second interconnecting members (18) having a dimension, generally in the direction of drive, less than the corresponding dimension of each first interconnecting member (17) and at least one of the second interconnecting members (18) having drive means (21) attached which, when energized, flexes the associated second interconnecting member, which in turn moves the second portion (15) of the flexural element relative to the first portion (14) so as to oscillate the driven member.
