The invention discloses a hand-hold digital apparatus which comprises a first body, a second body, a third body, rod members and an elevating system provided in the first body. The rod members have a first terminal, a second terminal, and a pivot point which is pivoted on the first body. The second body is slidingly coupled to the first body, coupled to the first terminal, and between the first body and the third body. The third body is slidingly coupled to the elevating system and is coupled to the rod members. When the third body is in translation motion relative to the first body along a first operation direction to drive the rod members to rotate, the second body is driven by the rod members, and is in translation motion relative to the first body along a second operation direction which is opposite to the first operation direction so as to be exposed by the third body, and the third body is close to the first body through falling of the elevating system.
