摘要:
A device for fastening a holding part on an eyeglass frame placed on a plate comprises an arm adapted to receive removably the holding part and a carriage on which the arm pivots between a raised loading end position and a lowered fitting end position. The carriage is mobile on a frame in a straight line between a retracted rest end position and an advanced end of travel position. A transmission system operative between a drive system and either the arm or the carriage is such that, at least when the carriage is in the vicinity of its advanced end of travel position, the arm is in its retracted fitting position. A locking device is operative between the arm and the carriage to lock the arm releasably to the carriage when in its lowered rest position.

A device for thermal printing of a rolled paper strip has a frame of which a fixed part comprises two lateral cheeks, which are perpendicular to an axis of articulation of a cover, and each comprise on their inner side fixed articulation means. The cover comprises two discs, which are accommodated between the two fixed cheeks, and each comprise on their outer side mobile articulation means which cooperate with the fixed articulation means. A latch, which is articulated around an axis which is parallel to the axis of articulation of the cover, cooperates with the cover and the fixed part of the frame, in order to provide locking/unlocking of the paper compartment on the fixed part of the frame.
