<p><P>PROBLEM TO BE SOLVED: To provide an electronic apparatus provided with a crystal vibrating reed, which prevents a weight section from vibrating in a different manner from vibration of a vibration arm section without following the vibration (amplitude) of the vibration arm section and stabilizes the vibration of the vibration arm section and a vibration frequency of the vibration arm section. <P>SOLUTION: A crystal vibrating reed 1, which is provided to an electronic apparatus, includes an intermediate weight section 4 formed by having the arm width W1 larger (thicker) than the arm width W of the vibration arm section 3 and smaller (thinner) than the arm width W2 of a tip weight section 5, and thereby causes the intermediate weight section 4 to follow vibration (amplitude) of a vibration arm section 3. The crystal vibrating reed 1 further includes the tip weight section 5 formed by having the arm width W2 larger (thicker) than the arm width W1 of the intermediate weight section 4, and thereby causes the tip weight section 5 to follow the vibration (amplitude) of the vibration arm section 3 and the intermediate weight section 4. Accordingly, vibration characteristics of the vibration arm section 3 can be stabilized. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
