Abstract
An electronic watch includes an including a package in which an oscillator and a watch control integrated circuit are housed, a circuit board having an elastic function, the circuit board including a first face and a second face, a first member provided with a plurality of first protrusions, and a second member provided with a second protrusion facing the first protrusion with the circuit board interposed therebetween, in which a plurality of clamping positions are clamped between the first protrusion and the second protrusion, A1>P1>A2>0, where A1 is a length of the first protrusion, A2 is a length of the second protrusion, and P1 is a thickness of the oscillation device.
Claims8
An electronic watch, comprising:
- an oscillation device including a package in which an oscillator and a watch control integrated circuit are housed;
- a circuit board having an elastic function, the circuit board including a first face and a second face having a front-back relationship with the first face;
- a first member disposed to face the first face and provided with a plurality of first protrusions;
- and
- a second member disposed to face the second face and provided with a second protrusion facing the first protrusion with the circuit board interposed therebetween, wherein
- the oscillation device is mounted at the first face of the circuit board,
- a plurality of clamping positions at a predetermined distance in an outward direction from an outer edge of the oscillation device are clamped between the first protrusion and the second protrusion,
- A1>P1>A2>0, where A1 is a length of the first protrusion, A2 is a length of the second protrusion, and P1 is a thickness of the oscillation device, and
- a gap is formed on a side of the first face of the circuit board so that a minimum distance between the first face and the first member is not less than the length A1 and a gap is formed on a side of the second face of the circuit board so that a minimum distance between the second face and the second member is not less than the length A2.
