Abstract

PURPOSE:To convert easily with a high accuracy a millimeter to an inch by converting a moving extent of a moving body to a distortion quantity, converting its distortion quantity to an analog signal by a strain gauge, and also converting it to a digital signal. CONSTITUTION:A spindle 2 being a moving body is moved relatively to a frame body 1. A spring means 4 contacts to a spring hooking part 3, and converts a moving extent of the spring hooking part 3, namely, a moving extent of the spindle 2, to a distortion quantity. A distortion quantity converting part is formed by the spring means 4 and the spring hooking part 3. A strain gauge 10 is fixed to the spring means 4 and the distortion quantity is converted to an analog signal A. Subsequently, it is converted to a digital signal B by an A/D converting part 11, and visualized and displayed by a display part 12.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the detection of a length measuring instrument such as a digital linear scale, digital dial gauge or digital electric micrometer.

Conventional digital dial gauges have a fixed scale with a light and dark pattern at equal intervals attached to the frame, a moving scale with a light and dark pattern at equal intervals attached to the spindle, and a pair of scales held between the two scales. Then, a light emitting element and a light receiving element are arranged facing each other, and the periodic brightness and darkness changes in the light caused by the relative movement of a pair of scales are photoelectrically converted into a nearly sinusoidal waveform by the light receiving element. It is known as a counting type length measuring device that digitally displays the amount of movement of the spindle on the display section via a circuit and an up/down counter.

However, in such a digital dial gauge, there is a limit to the counting speed of the up/down counter, and as a result, if the falling speed of the spindle increases, malfunctions such as counting errors will occur. It requires a damper mechanism to hold it down, and on top of that, the minimum unit for counting is predetermined, making it difficult to convert from millimeters to inches, and even if conversion is possible, there will be a considerable conversion error. It had drawbacks such as.

The present invention was made in view of the above-mentioned drawbacks, and it converts the amount of movement of a moving object into an amount of strain, and converts the amount of strain into an analog signal using a strain gauge (resistance wire strain gauge, semiconductor strain gauge, etc.). Then, the analog signal is converted into a digital signal by the AI converter, and essentially the analog signal does not cause malfunctions such as counting errors, and the analog signal can be freely converted into any arbitrary signal by an amplifier. The purpose is to provide an advanced sub-length tool that can easily convert from millimeters to inches, or vice versa, because it can multiply or divide values. The gist of the present invention for achieving the above object is as described in the claims above.
