    • A probe measuring device in which a probe is supported by a Y-axis stage (4) supported via a linear guide by a beam (32) at the top of a portal frame that moves freely in the X-axis direction relative to an object to be measured, wherein deterioration in measurement accuracy due to abrasion of the linear guide is prevented. The linear guide is composed of a pair of guide rails (51, 52) fixed to the undersurface of the beam (32), and a pair of linear-motion bearings (53, 54) that come into moveable contact with guide surfaces (51a, 52a), which are inclined relative to the vertical plane of the guide rails (51, 52). One of the linear-motion bearings (54) is made to float freely in the X-axis direction and the vertical direction relative to the Y-axis stage (4). An urging means (55), which urges the linear-motion bearing (54) in the X-axis direction in such a manner as to press the bearing against the guide surface (52a) of the guide rail (52), is disposed on the Y-axis stage (4), a second urging means (56), which urges the linear-motion bearing (54) downward, is disposed on the beam (32) side, and the direction of the vector of the resultant force of the urging forces of both urging means (55, 56) is thereby made to coincide with the normal direction of the guide surface (52a).

    • PROBLEM TO BE SOLVED: To provide an inkjet-type printing head which enables a mending of a discharge failure due to damage inflicted to a piezoelectric vibrator and is free from the deterioration of liquid droplet discharging performance even after the mending, as well as a discharge device. SOLUTION: This printing head 1 is of the following structure: each different type of elastic member 5 is arranged on the top of each pressure generating chamber 9 of a printing head 1, and the end part of each different type of piezoelectric vibrator 4 is set in contact with each elastic member 5. In addition, an enclosure 2 for the printing head 1 includes a plurality of fixed plates 3 set in place, and each piezoelectric vibrator 4 is fixedly attached to either one of the fixed plates 3 by a part of the piezoelectric vibrator 4 separated from the elastic member 5. Each fixed plate 3 is constituted in the way that it is individually detachable from an enclosure 2 while the other fixed plate 3 is fixedly attached to the enclosure 2. When a discharge failure occurs due to troubles of some of the piezoelectric vibrators 4, the fixed plate 3 related to the faulty piezoelectric vibrator 4 can be removed from the enclosure 2 and repaired. Since the contact state between the elastic member 5 and the piezoelectric vibrator 4 remains unchanged before and after the repair, the discharge performance does not deteriorate.
