Abstract

Abstract An identification code reader for a blood sample container (28) is incorporated in a blood analyzer (18,20,22). This reader incorporates an elastic member (42) which engages the top of the sample container (28), rotary means (48,50,52) for rotating the elastic member, up and down movement means (46,54) for moving the elastic member up and down, rotational/up and down movement control means (56), a code reader (19) for reading the sample code (e.g. bar code) (32), and reading control means (57) for controlling reading of the identification code (32) while rotating the sample container (28) in either direction. With the elastic member (42) abutting against the top of the sample container (28), first by rotating in one direction, the identification code (32) is read by the code reader (19). If this reading is unsuccessful, the elastic member (42) is rotated in the other direction to again attempt to read the sample identification code.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 146 words
An identification code reader for reading an identification code (32) on a sample container (28) in a sample rack (26), the identification code reader comprising: a driving member (42) for driving the sample container (28); rotary means (48, 50, 52) for rotating the driving member (42); up and down movement means (46, 54) for moving the driving member (42) up and down; rotational/up and down movement control means (56) connected to the rotary means (48, 50, 52) and up and down movement means (46, 54); identification code reader means (19) for reading the identification code (32) on the sample container (28); and reading control means (57) connected to the identification code reader means (19) for controlling reading of the identification code (32) while rotating the sample container (28) in one or, as necessary, both directions by engaging the driving member (42) with the sample container (28).
Claim 2
Dependent Claim 146 words
An identification code reader for reading an identification code (32) on a sample container (28) in a sample rack (26), the identification code reader comprising: a driving member (42) for driving the sample container (28); rotary means (48, 50, 52) for rotating the driving member (42); up and down movement means (46, 54) for moving the driving member (42) up and down; rotational/up and down movement control means (56) connected to the rotary means (48, 50, 52) and up and down movement means (46, 54); identification code reader means (19) for reading the identification code (32) on the sample container (28); and reading control means (57) connected to the identification code reader means (19) for controlling reading of the identification code (32) while rotating the sample container (28) in one or, as necessary, both directions by engaging the driving member (42) with the sample container (28).
Claim 3
Dependent Claim 27 words
An identification code reader according to claim 1, wherein the driving member (42) is an elastic member (42) engageable with the top of the sample container (28).
Claim 4
Dependent Claim 91 words
An identification code reader according to claim 1 or 2, wherein the reading control means (57) and rotational/up and down movement control means (56) are arranged to bring the driving member (42) into engagement with the sample container (28), to rotate the sample container (28) in one direction whilst the reader means (19) attempts to read the identification code (32), and, if the code (32) is not read, to rotate the sample container (28) in the other direction whilst the reader means (19) again attempts to read the identification code (32).
Claim 5
Dependent Claim 20 words
An identification code reader according to claims 2 and 3, wherein the bottom of the elastic member (42) is convex.
