    摘要： Provided is a machine tool that can suppress an increase in centrifugal force which is generated when turning an end effector, and prevent an increase in route errors of the end effector. This machine tool comprises: a rotary unit that rotates around a first axis; a first arm extending from the rotary unit; a second arm that is connected to the first arm, and supports an end effector; a single power source that is configured to supply power to the rotary unit and the second arm; and a switching mechanism that is configured to switch a destination of power supply from the power source, from one of the rotary unit and the second arm to the other. The second arm is configured to rotate around a second axis intersecting the first axis.

    摘要： The present invention provides a means which is capable of solving both the problem of burying with respect to coated paper and the problem of print density with respect to non-coated paper. According to the present invention, a printing device 10 ejects an aqueous ink for recording onto a sheet 6 from a printing head 34, said sheet 6 being conveyed in a conveyance direction, and heats the aqueous ink for recording by means of a heater 36 at a cumulative heat quantity Q1 under the condition that the recording medium is determined to be coated paper, while heating the aqueous ink for recording by means of the heater 36 at a cumulative heat quantity Q2 under the condition that the recording medium is determined not to be coated paper. The aqueous ink for recording contains a resin dispersed pigment, fine resin particles, a water-soluble organic compound and water. The melting point of the water-soluble organic compound is within the range of from 20°C to 55°C. The viscosity of a 50% by mass aqueous solution of the water-soluble organic compound is 8.5 mPa·s or more at 20°C, while being 90 mPa·s or less at 50°C.
