This invention combines four movements for the back of a folding type or flat bed camera. 1. A rising back, 2. shifting from side to side, 3. lateral swing and 4. tilting toward front or back. All these movements are achieved without using a center pivoting point. Doing it in a continuous working procedure, efficiently and with ease of movement with positive locking. The locking of the vertical movement clamping is accomplished on the sliding member and pivoting on the bottom axis. Means are provided for pivoting from either left or right side with its clamping means when camera is in focus.
