Abstract
An improved mounting apparatus of a shelf housing printed circuit boards in a frame is provided. The shelf is designed to prevent mechanical damage to itself and to the printed circuit boards inside the shelf in the event of deformation of the frame due to vibration during transportation or earthquakes. Guide members which enclose the printed circuit boards are fastened to supporting members in such a manner that the guide members can shift position lengthwise along the supporting members. Thus, mechanical stress causing the frame to deform from a rectangle into a parallelogram does not also deform the guide members holding the printed circuit boards. Accordingly, damage to soldered connections or circuit components on printed circuit boards is prevented.
