Abstract
Abstract An automatic sample delivery apparatus for delivering selectively emergency samples and standard samples by interrupting the delivery of successive routine samples, including a main-turntable on which a plurality of emergency and standard sample vessel holding recesses are formed equidistantly along a first circle, a plurality of sub-turntables arranged rotatably on the main-turntable, each having a plurality of routine sample vessel holding recesses formed equidistantly along a second circle, a main-motor for rotating the main-turntable such that any one of the sub-turntables is indexed into a sample delivery position and any one of the emergency and standard sample holding recesses is indexed into a sample sucking position, and a sub-motor for rotating a sub-turntable indexed into the sample delivery position such that routine samples set on the relevant sub-turntable are indexed into the sample sucking position. Any of the routine, emergency and standard samples indexed into the sample sucking position is delivered into a reaction vessel by the same sample sucking device in the same manner.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
260 words
An apparatus for delivering automatically routine samples contained in routine sample vessels and special samples such as emergency samples and standard samples contained in special sample vessels to be analyzed by an automatic chemical analyzer, comprising: a plurality of routine sample holding devices each holding a plurality of routine sample vessels; a first driving device for driving the routine sample holding devices so as to feed the routine sample vessels along a first path; a common sample holding device having a plurality of positions for holding special sample vessels and a plurality of positions for supporting said routine sample holding devices; a second driving device for driving said common sample holding device so as to feed the special sample vessels along a second path which is arranged substantially at the same level as said first path and includes a portion substantially coincident with a portion of said first path at least at a sample sucking position; and a sample sucking device including a sucking probe for sucking routine samples and special samples indexed into said sample sucking position; wherein the routine sample holding devices are successively indexed into a sample delivery position by driving said second driving device, routine sample vessels held by a routine sample holding device indexed at the sample delivery position are successively indexed into the sample sucking position by driving said first driving device, and special samples held in the special sample holding positions on the common sample holding device are successively directly indexed into the sample sucking position by driving only said second driving device.
Claim 2
Independent Claim
260 words
An apparatus for delivering automatically routine samples contained in routine sample vessels and special samples such as emergency samples and standard samples contained in special sample vessels to be analyzed by an automatic chemical analyzer, comprising: a plurality of routine sample holding devices each holding a plurality of routine sample vessels; a first driving device for driving the routine sample holding devices so as to feed the routine sample vessels along a first path; a common sample holding device having a plurality of positions for holding special sample vessels and a plurality of positions for supporting said routine sample holding devices; a second driving device for driving said common sample holding device so as to feed the special sample vessels along a second path which is arranged substantially at the same level as said first path and includes a portion substantially coincident with a portion of said first path at least at a sample sucking position; and a sample sucking device including a sucking probe for sucking routine samples and special samples indexed into said sample sucking position; wherein the routine sample holding devices are successively indexed into a sample delivery position by driving said second driving device, routine sample vessels held by a routine sample holding device indexed at the sample delivery position are successively indexed into the sample sucking position by driving said first driving device, and special samples held in the special sample holding positions on the common sample holding device are successively directly indexed into the sample sucking position by driving only said second driving device.
Claim 3
Dependent Claim
28 words
An apparatus according to claim 1, further comprising means for reading information provided on routine sample vessels and special sample vessels at a substantially identical information reading position.
Claim 4
Dependent Claim
19 words
An apparatus according to claim 2, further comprising means for reading information provided on the routine sample holding devices.
Claim 5
Dependent Claim
18 words
An apparatus according to claim 3, further comprising means for detecting information provided on the special sample vessels.
Claim 6
Dependent Claim
100 words
An apparatus according to claim 1, wherein each of said routine sample holding devices comprises a sub-turntable having a plurality of routine sample vessel holding positions arranged equidistantly along a first circle thereon, said common sample holding device comprises a main-turntable on which said sub-turntables are arranged equidistantly along a second circle, and said special sample holding positions are provided on said main-turntable at positions between successive sub-turntables along a third circle, whereby a first circle of a sub-turntable indexed at the sample delivery position is crossed with said third circle on the main-turntable substantially at the sample sucking position.
Claim 7
Dependent Claim
56 words
An apparatus according to claim 5, wherein said first driving means comprises shafts each secured to respective sub-turntables, gears each secured to respective shafts, a common gear which is engaged with a gear secured to a shaft of a sub-turntable which is indexed at the sample delivery position, and a motor secured to said common gear.
