Radiation image pickup apparatus

摘要

An imaging bed has a horizontally movable top panel for placing a subject to be imaged thereon, a touch switch mounted on the top panel for unlocking the top panel from a lock unit, and a protective cover positioned outwardly of the touch switch and tiltable toward and away from the top panel. The protective cover is engageable with the top panel in covering relation to the touch switch for preventing a finger from touching the touch switch when the protective cover is tilted toward the touch switch under external forces. The imaging bed is protected from an unwanted release from a fixed position, and can efficiently be operated.
