<p><P>PROBLEM TO BE SOLVED: To provide a structure for mounting an external unit, capable of sufficiently coping with static electricity of the external unit, and capable of assuring shock resistance of a unit substrate in the external unit. <P>SOLUTION: The external unit 2 includes a unit case 3, a unit substrate 11 arranged in the unit case 3, and a coil spring 12 for holding the unit substrate 11 in the unit case 3. Relating to the coil spring 12, with the intermediate part being contacted to a ground electrode 16 of the unit substrate 11, a lower end protrudes outside the unit case 3 to contact to a ground contact point plate 27 of an equipment body 1. Thus, the ground electrode 16 of the unit substrate 11 and the ground contact point part 27 of the equipment body 1 are electrically connected together by the coil spring 12. So, the static electricity generated at the external unit 2 is introduced to the equipment body 1 side. Further, the unit substrate 11 can be mounted in the external unit 2 in such state as elastically floated by the coil spring 12. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
