PURPOSE:To lower the height of a crystal resonator unit by providing a slot to a board and implanting the unit to said slot. CONSTITUTION:The crystal oscillator is formed by the crystal resonator, an IC, a capacitor, a resistive element and the board 4. In this case, the board 4 is provided with the slot 10. The crystal resonator unit is implanted and fixed to said slot 10. Thus, the height of the unit is lowered. |
