ABSTRACT:
An object of the present invention, which is a printed circuit board housing apparatus, is to allow the state of the printed circuit boards inside a rack (fully loaded or in mid-process, or the like) to be determined at a glance from outside the rack, so as to ensure that printed circuit boards are controlled in each rack. To achieve this object, the printed circuit board housing apparatus pertaining to the present invention comprises a display mark on the exterior component of the rack side plates for displaying the state of the printed circuit boards inside the rack, and a shutter for switching the display of the display mark, as well as a drive component for sliding the shutter.
