ABSTRACT:
An apparatus for supporting a cathode-ray tube panel includes a pair of holders movable to come close to each other and to be separated from each other. Each holder includes elastic rollers. The panel is located between the rollers of the pair of holders. After the panel is located between the rollers of the holders, the holders are moved to a surfaces of the panel. The rollers of the holders are brought into contact with the surfaces of the panel. The holders are interlocked with an actuator. The actuator is interlocked with a lock plate through a ratchet mechanism. The holders can freely come close to each other by the ratchet mechanism although the lock plate is not pivoted. The holders can be brought into contact with panels having different sizes. In a contact state, the actuator locked with the lock plate through the ratchet mechanism is pivoted by a predetermined angle so as to cause the holders to come closer to each other. When the holders are thus moved, they are locked. Therefore, the rollers of the holders are kept in tight contact with the surfaces of the panel and are elastically deformed. The panel can be held at a constant contact pressure corresponding to the pivot angle.
