装置の防塵ドア機構。[Claims for Utility Model Registration] (1) A recording/reproducing device in which the entire pack is drawn into the device from the pack insertion slot by a loading mechanism, and the pack is ejected from the pack insertion slot, is divided into upper and lower parts, and a first dust-proof door is provided on the upper side and a second dust-proof door is provided on the lower side so as to be openable and closable, and the first dust-proof door is opened in conjunction with the pack ejection operation of the loading mechanism, and the A dust-proof door mechanism for a recording/reproducing apparatus, characterized in that the second dust-proof door is opened in conjunction with the movement of the pack due to the pack ejection operation of a loading mechanism. (2) The first dustproof door is elastically biased in the closing direction by a first spring, and the shaft is protruded from a first cam that rotates in conjunction with the pack discharging operation of the loading mechanism. The action causes the second spring to open against the elasticity of the first spring.
The dustproof door is connected to the rotation of a second cam that projects into and retreats into the pack insertion path as it rotates, and this second cam is elastically biased by a second spring so as to protrude into the pack insertion path. The second dust-proof door is closed with the second cam protruding into the pack insertion path, and the second cam is rotated by the movement of the pack due to the pack ejecting operation of the loading mechanism. 2. The dust-proof door mechanism for a recording/reproducing apparatus according to claim 1, wherein the second dust-proof door is opened when the door is opened.
