<P>PROBLEM TO BE SOLVED: To prevent an abnormal state of short-circuiting an electronic circuit part in incorporating a button cell into an electronic equipment. <P>SOLUTION: With a button cell holding structure, a negative terminal 22 has two arms formed by folding in V shape a sheet of long and slender conductive elastic member, of which, a relatively light one is clad with an insulating cover 22d to make up an operation arm 22b, and the other is to be a contact arm 22a. The negative terminal 22 is fitted to a substrate 40 with its folded part 22c supported in free see-saw rotation between a fulcrum presser foot part 30a formed on a bottom board 30 and the substrate 40. With such a see-saw structure, the tip of a positive terminal 21 and the tip of the contact arm 22a of the negative terminal 22 are prevented from coming in contact at the same time with a negative electrode face of the button cell 10. <P>COPYRIGHT: (C)2003,JPO |
