Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
138 words
A dispensing machine comprising: a syringe pump (10); a liquid tank (11); a pump displacement mechanism (13) for displacing said syringe pump (10) between said liquid tank (11) and a container (4); a piston displacement mechanism (14) for displacing a piston of said syringe pump (10); a weigher (15) for measuring weights of said liquid tank (11) and liquid in said liquid tank (11); a drainage system (16, 17) for draining the liquid of said liquid tank (11); a supply system (2, 3, 5) for supplying the liquid to said liquid tank (11); and a control device (18) which controls displacement of said syringe pump (10) and said piston of said syringe pump (10) and actuation of said supply system (2, 3, 5) and said drainage system (16, 17) and reads measurement output signals of said weigher (15).
Claim 2
Dependent Claim
138 words
A dispensing machine comprising: a syringe pump (10); a liquid tank (11); a pump displacement mechanism (13) for displacing said syringe pump (10) between said liquid tank (11) and a container (4); a piston displacement mechanism (14) for displacing a piston of said syringe pump (10); a weigher (15) for measuring weights of said liquid tank (11) and liquid in said liquid tank (11); a drainage system (16, 17) for draining the liquid of said liquid tank (11); a supply system (2, 3, 5) for supplying the liquid to said liquid tank (11); and a control device (18) which controls displacement of said syringe pump (10) and said piston of said syringe pump (10) and actuation of said supply system (2, 3, 5) and said drainage system (16, 17) and reads measurement output signals of said weigher (15).
Claim 3
Dependent Claim
145 words
A dispensing machine as claimed in Claim 1, wherein a plurality of wells (a) are arranged in a pattern of a matrix on a culture tray (A) and a plurality of pipets (22) are provided so as to correspond to the wells (a) of one row or one column of the matrix such that said pipets (22) are simultaneously displaced, for exchange of the liquid of the wells (a), relative to said culture tray (A) at least in a vertical direction, said dispensing machine further including a pipet selection device for enabling selective use of said pipets (22), said pipet selection device comprising: a pipet support mechanism (25) for adjustably supporting said pipets (22) so as to allow individual positional adjustment of said pipets (22) in the vertical direction; and a stopper mechanism (50) for individually setting positions of distal ends of said pipets (22).
Claim 4
Dependent Claim
63 words
A dispensing machine as claimed in Claim 2, wherein said stopper mechanism (50) includes a plurality of stopper members (54) each for supporting a flange portion (49) of a tip (43) attached to each of said pipets (22) and a plurality of driving members (52) for displacing said stopper members (54), respectively so as to individually set heights of said stopper members (54).
Claim 5
Dependent Claim
148 words
A dispensing machine as claimed in Claim 1, wherein a plurality of wells (a) are arranged in a pattern of a matrix on a culture tray (A) and at least one pipet (22) for exchanging the liquid of the wells (a) is provided, said dispensing machine further including a tip exchange device for exchanging a tip (61) attached, through a jig (62) having a flange (63), to a distal end of said pipet (22), said tip exchange device comprising: a stopper means (64) for securing said pipet (22) through its engagement with said flange (63), which is formed with a first recess (85) for receiving said jig (62); a tip depressing means (65) for depressing said tip (61) downwardly, which is formed with a second recess (87) for receiving said jig (62); and a tip lifting means (66) for lifting a tip magazine (71) carrying said tip (61).
