1. A sample supply device comprising:
- a sample receiving channel for receiving a plurality of samples from a source;
a sample supply channel for supplying the samples to a position to be supplied;
first and second sample storage means for storing respective samples;
first and second pressurizing means, in communication with said first and second sample storage means, respectively, for extruding and aspirating samples stored in said first and second storage means; and
channel switching means capable of switching between a first mode and a second mode, with the first mode being a state in which said first sample storage means is connected to said sample suppy channel and said second sample storage means is connected to said sample receiving channel, and the second mode being a state in which said first sample storage means is connected to said sample receiving channel and said second sample storage means is connected to said sample supply channel.

Abstract
A sample supply device includes first and second sample supply means for independently receiving respective samples via a common channel and for supplying the samples to an inspection position. The device is controlled so that the second sample supply means performs a sample receiving operation and/or a washing operation with the channel, while the first sample supply means supplies the sample to the inspection position. A sample inspection apparatus inspects the sample at the inspection position principally using an optical method.
