Abstract
The invention has as an object to provide a reliable, failure-free tool holding apparatus which allows digitization of a tool holding apparatus having a tool moving function, is free from various problems encountered upon digitization, and does not cause an erroneous operation upon scattering and attachment of chips or cutting oil. In order to achieve this object, a scale member and a moving amount detecting means are arranged to oppose each other. The scale member is arranged at the side of a slide movable in a predetermined direction, and is moved following the movement of the slide. The moving amount detecting means is arranged at the side of the main body and supplies a predetermined number of oscillation pulses to a display in accordance with the moving amount of the scale member. The scale member is enclosed with stretchable members such as bellows members, and is moved in the enclosed, sealed space.
