PURPOSE:To make it possible to dispense specimen or reagent by a certain volume by constituting a dispensing device with a slide valve and a slide valve driving section. CONSTITUTION:A slide valve 10 has a disc 11 that has a center shaft 11a and is fixed at it lower section and a first central tube which has the center shaft 11a go through its inside. The slide valve 10 is provided with a first torating disc 12 that is mounted slidabley on the fixed disc 11, second, third and fourth rotating discs 13, 14 and 15 of the same shape as the first disc, and a disc 16 that is mounted on the fourth rotating disc 15 and fixed at its upper portion. In the slide valve driving section a small motor 12d is driven and thereby the first rotating disc 12 is rotated by 90 deg. and to match the vertical hole 12A of the rotating disc 12 to a second through-hole 18. With this arrangement specimen in the vertical hole 12A is transferred into the second through-hole 18. After this the same applies to the second, third and fourth rotating discs, 13, 14 and 15. |
