Abstract
A suction generating device for a sample analysis device is provided. The device comprises four parts, namely, a cover plate 61, a middle plate 62, a bottom plate 63 and an operation plate 64. A protruding portion 642 for compressing the suction generating chamber is formed in an approximately center portion on the lower side of the operation plate 64, a protruding portion 641 for operation is formed in an approximately center portion on the upper side of the operation plate 64. A cavity 631 for inserting the sample analysis device therein is formed in an approximately center portion in the bottom plate 63, and a hole 632 for light irradiation is punched in a determined portion in the cavity 631. A concave portion 623 for fitting the operation plate 64 therein is formed in the middle plate 62, and a window section 621 is formed in the center of the concave portion 623 to let the lower protruding portion 642 on the operation plate 64 protrude therethrough. A window section 611 is formed in the cover plate 61 to let the upper protruding portion 641 on the operation plate 64 protrude therethrough.
