The present invention may include a display for displaying objects including a mounting panel for mounting a light panel including a LED light, a graphics panel adjacent to the light panel which may include information to be displayed, a magnetic shelf being magnetically attracted to the mounting panel and being detachably connected to the display for displaying objects. The aperture member is disposed between an energy source and a substrate to be processed. At least one of the wires 7 is bended with respect to a reference straight line S which passes through the bonding pad 3 and the bonding pad 4 which are connected by the wire 7. During operation, the transmission of torsional vibrations back through the drive plate and springs to the armature plate is dampened by the compressed rubber rings.
