Direction of motion conversion mechanism, actuator device using the same, and reagent manufacturing apparatus

An actuator device including a direction of motion conversion mechanism adapted to convert translatory motion into rotary motion, the actuator device comprising:

• a translatory mechanism unit including a pin that is a cam follower arranged in a groove of a cam having the groove in a cylindrical surface and to which a three-way stopcock is connected, the cam follower adapted to relatively move along the groove, and to perform the translatory motion;
• a rotation mechanism in which the cam performs the rotary motion;
• and
• a pin drive unit adapted to cause the pin to perform the translatory motion along an extending direction of the cam, and to rotate the cam with respect to a central axis of the rotation mechanism unit, wherein
• a translatory axis of the translatory mechanism unit and a central axis of rotation of the rotation mechanism unit are parallel or on the same straight line,
• in a plan view in which the cylindrical surface is developed,
• the groove includes
• a first groove having a first inclination angle with respect to the central axis of rotation of the rotation mechanism unit,
• a second groove having a second inclination angle with respect to the central axis of rotation,
• a third groove having a third inclination angle with respect to the central axis of rotation, and
• a fourth groove having a fourth inclination angle with respect to the central axis of rotation,
• the first, second, third, and fourth grooves have a linked shape,
• directions of respective inclinations of the first groove and the third groove are opposite with respect to the central axis of rotation, and
• directions of respective inclinations of the second groove and the fourth groove are opposite with respect to the central axis of rotation.

A reagent manufacturing apparatus including an actuator device including a direction of motion conversion mechanism adapted to convert translatory motion into rotary motion, the reagent manufacturing apparatus comprising:

• the groove includes
• a first groove having a first inclination angle with respect to the central axis of rotation of the rotation mechanism unit,
• a second groove having a second inclination angle with respect to the central axis of rotation,
• a third groove having a third inclination angle with respect to the central axis of rotation, and
• a fourth groove having a fourth inclination angle with respect to the central axis of rotation,
• the first, second, third, and fourth grooves have a linked shape,
• directions of respective inclinations of the first groove and the third groove are opposite with respect to the central axis of rotation,
• directions of respective inclinations of the second groove and the fourth groove are opposite with respect to the central axis of rotation, and
• the control unit controls timing to divert the passage of the three-way stopcock.
