ABSTRACT:
An indexing device for storing the information such as telephone numbers and addresses. When one of a plurality of push-buttons with index codes is pressed, some of the numerous cards internally housed are lifted and retained by the cover at the time the cover opens, to show a selected card. The cover has, internally on one side, a projection to engage one side of the card stack when the cover is closed and has on the other side, a card-grip to hold the cards lifted when the button is pressed. The projection supports one side of the cards when the cards are lifted, and it enlarges the lifting amount of the other side (the card-grip side) of the lifted cards.
