PROBLEM TO BE SOLVED: To provide a mounting unit lifting device with durability capable of being miniaturized. SOLUTION: This device comprises a mounting base 2, which is a member upward and downward moved, mounting a mounting unit 6, and a base body 1 holding the mounting base 2. Upward and downward movement guiding mechanisms 4, 5 for guiding the upward and downward movement of the mounting base 2 are provided between the base body 1 and the mounting base 2. Lever mechanism 7, 8 having a braking force assisting function energizing an upward and downward moving force relative to the mounting base 2 are provided between the mounting base 2 and the base body 1 (on both of right and left sides). With this constitution, the mounting base 2 mounting the mounting unit 6 can be smoothly moved upward and downward in a stable state. COPYRIGHT: (C)2009,JPO&INPIT
