ABSTRACT:
A shutter mechanism for an electrode pad attached card and a contact comprises a slider which can reciprocally move forwardly and backwardly in accordance with insertion and withdrawal of an electrode pad attached card. A contact guide groove is formed in the slider in such a manner as to extend in a direction of the reciprocal movement of the slider and adapted to guide a contacting projection of a contact. A release groove is formed in a bottom surface of the contact guide groove, the release groove having a smaller width than that of the guide groove and extending in the direction of the reciprocal movement of the slider. The release groove is in opposing relation with the contacting projection, a slip portion formed at an area in the vicinity of the contacting projection, the slip portion being resiliently contacted with a stepped portion formed along an opening edge of the release groove. The slider is reciprocally moved with the slip portion resiliently contacting the stepped portion and canceling the resilient contact relation with the stepped portion at an end of the forward movement of the slider so that the contacting projection is resiliently contacted with the card electrode pad.
