Abstract

PURPOSE:To accurately open and close a cap by providing a cap opening and closing device with a rotation drive part for rotating a grip opening and closing drive part, an analog-to-digital converter for A/D converting the voltage value of a microresistor and a switch for turning a motor on and off by the operation of a personal computor. CONSTITUTION:A grip opening and closing drive part 3 is provided with grippers 31 and 32 for gripping a sample container 1 and a rotation drive part 4 enclosing a motor 5 therein rotates the grip opening and closing drive part 3. The cap 2 of the sample container 1 is gripped and released by a robot hand 12 at suitable intervals. A lead wire 8 connecting a motor 5 and an electric source 6 for said motor is provided with a switch 9 for turning on and off the motor 5 for the rotation drive part 4 by the operation of a personal computor 7. An A/D converter 10 amplifies with an operational amplifier the voltage across a microresistor 11 inserted into the lead wire in series therewith and the resulting value is A/D converted and fed into the personal computor 7. The threshold value of the A/D converted voltage at the time of closing a cap 2 is determined, the threshold values are continuously counted predetermined or more times and the switch 9 for the motor 5 is turned off.
