Description

  The present invention relates to a digital measuring instrument, provides accurate and simple surveying information, and is convenient and practical to use.

  General surveying instruments are classified according to their functions and types of objects to be measured. There are straight scales, triangle scales, tape measures, cloth scales, etc. Any kind of surveying instruments has a standard measurement memory installed and measures the surveyed objects. .

  As described above, various surveying instruments have convenient functions in use. However, the survey results are often not ideal. The cause is nothing but the uncertainty in the surveying process. This uncertain element includes the attitude at the time of surveying, the surveying method, the interpretation of surveying results, and the like. A posture that is not correct is not only disadvantageous for the surveying process, but also the surveying is biased and correct results cannot be obtained. The fact that the surveying method is inaccurate also affects the accuracy of the survey value. In addition, the interpretation of the survey result causes an error due to the eye position, and correct information cannot be obtained.

    The problem to be solved is that it is difficult to obtain a correct survey result with a known survey instrument.

  The present invention uses a liquid crystal display and, together with an optical sensor component, easily displays the measured numerical values and is easy to read. This digital measuring instrument is composed of a surveying component, a sensor component, a counter, a liquid crystal display, a liquid crystal driving component, and a power supply unit. In use, the most important feature is to measure the surveyed property, transmit the numerical information measured by the sensor parts to the counter, display it on the liquid crystal display, and interpret it.

  The digital measuring instrument of the present invention has an advantage that it provides accurate and simple surveying information, is convenient in use and has practicality.

  We provide digital measuring instruments that combine optical sensor components with liquid crystal displays. As a result, the measured numerical value is displayed on the liquid crystal display so that it is convenient and easy to read. It is practical because it is convenient and simple.

  As shown in FIG. 1, the digital measuring instrument 1 of the present invention includes the following. The survey component 10 includes a survey memory 11 of the international unit system and the yard / pound method, and measures the size of the survey object. In practice, it is manufactured with a base material such as a narrow rope, a plastic piece, a cloth, or a metal modification.

  The sensor component 20 is mutually equipped with the surveying component 10 and senses numerical information in the surveying memory obtained after surveying by the surveying component 10. In practice, an infrared sensor, contact spring piece or other optical sensor component is used.

  The counter 30 is composed of an IC, provides a switching between an international unit system (centimeter) and a yard-pound method (inch), and has a function of returning to zero, thereby avoiding acquisition of erroneous surveying numerical information.

  The liquid crystal display 40 is a liquid crystal display that can display up to four digits, and displays the measured numerical information.

  The liquid crystal driving component 50 is installed together with the liquid crystal display 40 and drives the liquid crystal display 40.

  The power supply unit 60 serves as a power supply source necessary for operating each of the units described above, and is a 3V or 1.5V DC power source in practice.

  When the above structure is assembled and actually used, the digital measuring instrument 1 is combined with a portable small article that we use in daily life. FIG. 2 shows a writing instrument, FIG. 3 shows a key holder, FIG. 4 shows a tape measure, and FIG. 5 shows a ruler. In addition to improving the function of a ready-made article, the convenience in use is enhanced.

  By combining the digital measuring instrument shown in FIGS. 2 to 5 with various articles, the digital measuring instrument 1 can be easily used anytime and anywhere. Surveying is performed simply by matching with the surveying article, and after the numerical value is determined, this numerical information is displayed through the liquid crystal display 40 and read.
