Title (EN) MOVEMENT SENSOR IN A MICRO ELECTRO-MECHANICAL DEVICE
(FR) DETECTEUR DE MOUVEMENT DANS UN DISPOSITIF ELECTROMECANIQUE
Abstract:
(EN) A micro electro-mechanical device embodied within an ink ejection nozzle having an actuating arm that is caused to move an ink displacing paddle (27) when heat inducing electric current is passed through the actuating arm. The device incorporates a movement sensor (37, 39) that comprises a moving contact element (37) that is formed integrally with the actuating arm, a fixed contact element (39) that is formed integrally with a support structure of the device and electrical elements formed within the support structure for detecting contact that is made between the fixed contact element (39) and the moving contact element (37). The movement sensor (37, 39) is provided for the purpose of facilitating testing of the device under various operating conditions.
(FR) L'invention concerne un dispositif électromécanique incorporé dans une buse d'éjection d'encre et pourvu d'un bras de commande qui entraîne une palette de déplacement de l'encre (27) lorsque un courant électrique induisant de la chaleur passe dans le bras de commande. Ce dispositif comprend un détecteur de mouvement (37, 39) qui comprend un élément de contact mobile (37) solidaire du bras de commande, un élément de contact fixe (39) solidaire d'une structure de support du dispositif et des éléments électriques formés dans la structure de support afin de détecter un contact entre l'élément de contact fixe (39) et l'élément de contact mobile (37). Le but du détecteur de mouvement (37, 39) est de faciliter l'essai du dispositif dans différentes conditions de fonctionnement.
