Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
168 words
A cutter device of rolled copy paper for electronic copying machines having two sets of feeding rolls, comprising a stationary arcuate guide plate disposed above a passage of the copy paper between the two sets of the feeding rolls, a movable arcuate guide plate disposed below said passage between the two sets of the feeding rolls, the two guide plates forming an open loop-shape bypass passage of the copy paper, a V-shaped spring having one leg engaging that surface of the movable guide plate which is opposite to the stationary guide plate, a shaft means pivotally supporting one edge of the movable guide plate, a limiter arm means integrally secured to the movable guide plate adjacent said shaft means, a stationary pin means engageable with said limiter arm means when the movable guide plate is moved away from the stationary guide plate, and a cutting member means being actuated in relation with the rotation of the feeding rolls, whereby cutting the copy paper without interrupting the feeding thereof.
Claim 2
Dependent Claim
168 words
