<p>PURPOSE:To decrease a fitting space to an electronic equipment, to reduce the cost of parts and to improve productivity by fixing the base parts of two crystal resonators, whose resonance frequencies are different, to fixing parts in the two corners of diagonal positions in a ceramic container. CONSTITUTION:In a container 3 of an insulation material such as ceramic, etc., crystal resonators 1 and 4 of the different frequencies fix base parts 1' and 4' into the container. Fixing parts 2 and 5, which are also used as electrodes, to support and conduct these crystal resonators 1 and 4 are provided in the two corners of the diagonal positions in the container 3 and the crystal resonators are fixed. Thus, the two crystal resonators can be housed in the box-shaped container of the same dimension as a conventional product and the space of the electronic equipment, to which this product is applied, can be reduced. Then, the cost of parts can be lowered and the productivity can be improved.</p> |
