Abstract

PURPOSE:To prevent the noise of cutter case from being emitted at the time of cutting a running sheet of paper with a saw blade so effectively as absorbing it into an elastic member by attaching this elastic member to at least one side of the contact surfaces between a guide plate and a pinch plate. CONSTITUTION:A cutter case 1 consists of a support block 2, a pair of guide plates 3, 3' erected at both sides of this support block 2, a pair of pinch plates 4, 4' being inserted into these guide plates 3, 3' free of slide motion via a pair of springs 6, 6' and a fixed saw blade 5 lying between these pinch plates 4, 4'. Then, each of elastic members 7,7', for example, urethane rubber are attached to contact surfaces 3a, 3a' of these guide plates 3, 3' by means of baking, while these elastic members 7,7' are attached to contact surfaces 4a, 4a' of the pinch plates 4, 4' as well by means of urethane rubber baking and so on. Here these elastic members 7, 7' are attached to either of the contact surfaces 3a, 3a' of the guide plates 3, 3' or the contact surfaces 4a, 4a' of the pinch plates 4, 4'.
