A length measuring device includes a hook () to which a ring of the tape tip is hooked and retained, and the hook () includes a first hook (-) and a second hook (-) provided on both sides of an outlet perpendicularly to each other, in which, when the ring at a leading end of the tape tip is hooked with the first hook or the second hook, a surface of the first hook or the second hook is brought into contact with a rectangular inner peripheral surface of the fastening hole (), such that the tape tip is retained perpendicularly to the first hook or the second hook.

Length measuring device

Provided is a length measuring device, which includes a first case including a bobbin axis at a center, a second case to which a circuit board is attached, a bobbin mounted on the bobbin axis and around which a tape is wound, a sensor for sensing an amount of rotation of the bobbin rotated by the tape being pull-out, and first and second anti-tilt members for preventing tilting of the bobbin during rotation of the bobbin.

Provided is a length measuring device having an automatic zero point adjusting function and a control method thereof. The length measuring device includes a line to which a hook part is attached at one end, a case having an opening formed therein, a rotating part to be rotated according to extraction or retraction of the line out of or into the case through the opening, a rotation sensing part which senses a rotation of the rotating part, and a control part which converts an amount of rotation of the rotating part into a length measurement value and resets the converted length measurement value to a predetermined value when the length measuring device is in a first state.
