Abstract
A crystal holder is provided which is capable of supporting any one of a plurality of piezoelectric crystals having different preselected diameters. The crystal holder includes two side portions, each portion having a stair step-like structure, the stair steps of one side portion leading upwardly and away from the stair steps of the remaining side portion. Each step of one side portion is respectively horizontally aligned with a corresponding step of the remaining side portion such that each step pair thus formed has a different distance therebetween and is thus capable of accepting for mounting one of a plurality of piezoelectric crystals having preselected diameters corresponding to the distances between the steps of the step pairs.
