Abstract
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.
Claims9
A length measuring device, comprising:
- 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;
- a first anti-tilt member including a first horizontal fixing part coupled to the circuit board and a first vertical fixing part formed in a cylindrical shape vertically to the first horizontal fixing part to prevent tilting of the bobbin during rotation of the bobbin;
- and
- a bearing in contact with an inner circumferential surface of the first vertical fixing part,
- thereby preventing a tilting motion of the rotating bobbin.
