Abstract
The present invention provides a data-memory in and out mechanism including a carriage for installing a data storage medium and a driving mechanism. The carriage can be movably installed in a housing. The driving mechanism includes the piezoelectric motor used for driving the carriage out and/or in relative to the housing. The piezoelectric motor is installed either in the carriage or in the housing and provided with a friction head, which is in friction contact with either one of the carriage or the housing where the piezoelectric motor is not situated. The data-memory in and out mechanism enables automatic sliding in and out of a carriage. Besides, as the piezoelectric motor is ultrathin and has no need to be used with a reduction gear case, the whole data-memory in and out mechanism can be ultrathin, as a result. The data-memory in and out mechanism is particularly applicable to notebook computers, DVD players and other flat-shaped electronic equipment.
