Abstract:
A liquid-injecting device (1) comprises: a first weighing unit (10a) comprising a first piston (12a) moving in a first weighing space (13a) in a first cylinder (11a); a second weighing unit (10b) comprising a second piston (12b) moving in a second weighing space (13b) in a second cylinder (11b); a first dispenser (20a) for injecting a liquid (19) into a first container (90a); a second dispenser (20b) for injecting the liquid into a second container (90b); a drive mechanism (30) for operating the first piston and the second piston in synchronism; and a first stroke converting mechanism (60a) which is disposed between the first piston and the drive mechanism to uniquely convert and transmit a first stroke of the drive mechanism to the first piston, the first stroke converting mechanism independently controlling the amount of movement of the first piston relative to the amount of movement of the second piston.
