Abstract

A digital indicator 1 includes a body case (10), a spindle (30) provided to the body case (10), the spindle (30) being movable in an axial direction, a displacement detector (40) that detects a moving amount of the spindle (30), and a digital display (50) that digitally displays the moving amount detected by the displacement detector (40). The display surface of the digital display (50) is arranged on the body case (10) in an attitude substantially orthogonal to the moving direction of the spindle (30) and deviated from the moving axis of the spindle (30).

Claims

1. A digital measuring instrument comprising:

a body case;

a spindle provided to the body case, the spindle being movable in the axial direction;

a displacement detector that detects a moving amount of the spindle; and

a digital display that digitally displays the moving amount detected by the displacement detector,

wherein a display surface of the digital display is arranged on the body case in an attitude substantially orthogonal to the moving direction of the spindle and deviated from the moving axis of the spindle.

2. The digital measuring instrument according to claim 1, wherein

the spindle penetrates the body case and is provided with a probe at one end thereof projecting from the body case, and

the display surface of the digital display is arranged on a surface of the body case which supports the other end of the spindle.

3. The digital measuring instrument according to claim 1, further comprising:

an output connector for outputting the moving amount of the spindle detected by the displacement detector to the outside, the output connector being arranged on a surface of the body case substantially parallel with the moving direction of the spindle.

4. The digital measuring instrument according to claim 1, further comprising:

a display inversion selector that inverts information displayed on the digital display by 180°

.

5. The digital measuring instrument according to claim 4, wherein

the digital display includes plural digits of 7-segment display elements each being formed by arraying seven segments in the shape of “

8”

, and

the display inversion selector has a selection switch and switches the lighting condition of the 7-segment display elements in accordance with the state of the selection switch so that a figure displayed on the digital display is inverted by 180°

.
