  • This configuration is also applicable to the first and the second embodiments.
  • the ejection protection mechanism of card media according to the present invention is effectively protecting the ejection of the card media inserted into the compartment by electrically closing the protection member. That is, the card media can not be ejected when it is accessed or in operation, thereby effectively protecting the stored information in the card media from damage.
  • the electrical operation performed by softward is thief-free or effective to prevent the card media from being stolen. Another advantage is to avoid any damage to the electrical contacts due to smooth electrical ejection operation of the card media.
  • engagement of the manual insertion operation and electrically ejection operation is effected only in the pushing or ejecting direction. This ensures free manual insertion/ejection unless the protect operation is effected.
  • the electrical driving mechanism can be located at only one side of the card compartment, thereby enabling to provide dual card compartment construction for controlling 2 cards in a limited space to achieve a compact design.

Abstract

La présente invention permet d'équiper un appareil de lecture/écriture d'un mécanisme de protection à système électrique pour l'éjection des cartes électroniques renfermées dans le compartiment des cartes électroniques. Une fois qu'une carte (10) a été insérée manuellement dans un connecteur (11), une barrette coulissante (24) est actionnée par un moteur (31) de façon à entraîner un axe d'actionnement (35) retenu dans une rainure à effet de came (33). Une partie en crochet (39) d'un bras de protection (34) entre en contact avec l'épaulement (40) de l'extrémité arrière de la carte (10) de façon à empêcher l'éjection de la carte. Le moteur (31) est mis en rotation dans le sens inverse pour mouvoir dans le sens inverse la barrette coulissante (24). La rainure à effet de came (33) amène l'axe d'actionnement (35) à faire pivoter la partie en crochet (39) jusqu'à occuper la position ouverte, et simultanément, l'axe d'entraînement (23) fait pivoter le poussoir (18) qui entraîne le porte-carte (12) au moyen de son axe fixe (16). Des languettes (14) permettent d'éjecter plus facilement la carte (10) du connecteur (11).
