量感或いは限界値に対する接近状態を直感的に知ること
ができないという欠点を有した。A test indicator or other gauge that uses sound to detect whether the dimensions of the object to be measured are within an allowable range, such as an arrow difference, can be used to determine whether the dimensions of the object to be measured are within the allowable range, for example, from the position of the probe in the measuring direction when the tip is brought into contact with the object to be measured. It's been done. Conventionally, this reset gauge consists of a dial gauge with a defining contact whose position can be adjusted using an adjustment screw, etc., and a movable contact which moves in conjunction with the pointer of a spindle or Hiro dial gauge. For this reason, we have developed a so-called mechanical Z-sut gauge that incorporates multiple pairs of contacts and detects whether the dimensions of the object to be measured are within the allowable range based on the presence or absence of electrical contact between each contact, and the movement of the spindle. It is treated as an electrical signal, and the displayed value of the measured value is set to zero at the reference dimension, so that it is possible to detect whether or not the dimension of the object to be measured is within the tolerance based on the deviation from the reference dimension. , the so-called electric lint gauge is known.However, in the former mechanical lint gauge, the measured value is displayed in an analog manner using a pointer, so the sense of volume of the measured value and the approach to the limit value etc. are intuitive. However, it required skill to read the measured values accurately. Also, it was difficult to change the measuring tube Wi because the filling plate could not be changed easily! ! !
In addition, because the pointer was moved mechanically in conjunction with the displacement of the measuring point, if the dimensions of the object to be measured were abnormally large or if an impact was applied to the measuring point, On the other hand, according to the latter electric type gauge, there were disadvantages such as the pointer going off the scale and making it impossible to read the measured value, or the analog display device breaking down. Since the numerical value of the measurement result is electrically displayed digitally, it is very easy to read the constant measurement value, but it has the disadvantage that it is not possible to intuitively know the volume of the measured W value or the state of approaching the limit value. I had it.

d and the upper limit value pointer 26e are displayed. When the preparation for measurement is completed in this way and measurement is performed by slightly moving the measuring point 10 in the vertical direction by operating the release 40, the measured value is displayed on the digital display 24. Ana proverbs are displayed digitally as well! Display 8260 pointer 26
b moves. Therefore, not only can the measured value be easily read, but also the volume of the measured value can be seen from the position of the pointer i6b, and further, the lower limit pointer 264. From the approach state to the upper limit value guide 26e, the state of the measured value with respect to the limit value lIt
It's exciting to know intuitively◎ Also, if the measured value is above the lower limit and below the upper limit, the pass display section 26f lights up and the pass display section turns off, and when the measured value exceeds the above range 8, a failure occurs. By turning on the pass indicator 26g and indicating "fail", you can easily know whether the measured value is within the limit or not.
