There is provided with a resonator which can correct the resonance frequency of a vibrator in a wide range and with a high accuracy and also provided with an oscillator using the resonator. The reject box is disposed on a path diverged from a bill transport path which transports bills from the temporary storage box to the bill discriminating unit. In one embodiment, the substantially monochromatic photoexciting light is a continuous beam of light, and the resultant steady-state far red and near infrared SW emission from the tissue sample is used to characterize the condition of the tissue sample. The inflator remains in the housing and inflation gas is conveyed to the cushion through the housing. The closure prevents dripping of the lighter fraction when the container is inverted and allows the heavier fraction to displace the lighter fraction adjacent to the dispensing aperture before dispensing occurs.
