ERASING DEVICE FOR TABLET INPUT DEVICE

PURPOSE:To prevent damages due to wear, by forming a erasing device for tablet input device freely rotatably consisting of a pressing element which is accommodated in a recess of a chalk eraser forming the recess on the erase plane and a part of which is exposed on the erase plane. CONSTITUTION:A notch 21 is formed to a wooden plate 14, holding metal fixtures 23a, 23b of a presser 22 are fixed around the notch 21 with wood screws 25 together with a spacer 24, a circumference of round holes made to an erase plane 13a of a cloth 13 is latched with a retaining metal fixture 26 tightened together with the wood screws 25 and a recess 27 is formed to the erase plane 13a. In the recess 27, the presser 22 of spherical shape held freely rotatably with the holding metal fixtures 23a and 23b is accommodated, a part of the presser 22 is exposed to the erase plane 13a and the tip is projected with almost the same circumference as the erase plane 13a. The tip is swept out to erase the pattern on a black board, the presser 22 pushes a tablet and outputs a reset electric signal to erase the signal. Thus, the wear-proof performance can be improved.
