Claims

[Scope of Claim for Utility Model Registration] 1. A plurality of cylindrical length measuring rods having successively smaller diameters are inserted into a cylindrical external case rod so as to be freely removable in one direction, and The long rod is provided with a locking mechanism that presses into contact with each outer length measuring rod or external case rod, and length measuring points are arranged at regular intervals and can be freely rewound inside the rod housing side of the external case rod. The tip of the length measuring tape wrapped around the tape is inserted into the narrowest length measuring rod and fixed to the end on the rod drawer side, and as the length measuring tape moves, each length measuring point is a detection unit that detects and outputs it as an electrical signal;
A counter section that counts the detection signal of this detection section, a control section that performs a desired calculation based on the count signal of this counter section, and a display section that digitally displays the measured length value based on the output signal of this control section. A digital display length measuring instrument characterized by being equipped with. 2. The digital display length measuring instrument according to claim 1 of the utility model registration claim, in which a single continuous straight line is displayed along the longitudinal direction on the outer surface of the outer case rod and each length measuring rod. 3. Scope of Utility Model Registration Claim 1: The pressure force of the locking mechanism provided on each length measuring rod is increased in order from the narrowest side length rod to the length measuring rod whose diameter increases. Or the digital display length measuring device according to paragraph 2. 4 Any of claims 1 to 3 for utility model registration in which an initial state detection switch that is turned on by the rod drawer side end of the narrowest length measuring rod is attached to the rod drawer side end of the external case rod. Digital display length measuring device described in Crab. 5. Attach a tip metal fitting to the end of the narrowest side rod on the rod drawer side, and this metal tip contacts the initial state detection switch and turns it on, thereby energizing the control unit, detection unit, display unit, etc. A digital display length measuring device according to any one of claims 1 to 4, which is configured to display an initial value on the display section. 6. The digital display length measuring instrument according to claim 5 of the utility model registration, wherein a recess for drawing out the tip metal fitting is formed on the edge of the outer case rod on the rod drawer side. 7. A mode switching key is attached as an external setting key, and the control unit is configured to change the measurement value to the meter based on the meter unit by pressing the mode switching key.
A digital display length measuring instrument according to any one of claims 1 to 6, which is provided with means for converting into units of inch and foot inch.
