    Abstract: A piezoelectric element feeder for feeding a piezoelectric element, includes a drawing unit that draws a first electrode surface of the piezoelectric element with use of negative pressure and transfers the piezoelectric element onto the actuator attaching part and a probe movably supported with the drawing unit and used to measure electric characteristics of the piezoelectric element. A front end of the probe is brought into contact with the first electrode surface when or just before the drawing unit draws the first electrode surface, to enable a measurement of the electric characteristics of the piezoelectric element.

    Abstract: A head driving device includes a base member, a head supporting member, a beam member, a piezoelectric unit, and a reinforcement member. The reinforcement member includes a first portion and a second portion. The first portion is arranged between a first end portion in a length direction of a head member and the base member. The second member is arranged between a second end portion in a length direction of the head member and the base member. The reinforcement member allows the head supporting member to move in a direction along a surface of tape and controls the head supporting member from moving in a thickness direction of the head member.
