Abstract
A cutting device is provided for use with a printer having a plurality of movable blades which are disposed in side-by-side relationship and driven in a direction perpendicular to the length of the blade. A plurality of solenoids are provided for driving each movable blade. A spring, which is arranged to be depressed by the movement of the movable blade, applies a pressure to the paper to fix the paper in position before the movable blade reaches the cutting position.
Claims9
A cutting device, comprising:
- a plurality of movable blades for cutting paper placed in said device along a cutting direction transverse to a longitudinal dimension of said paper, said movable blades being aligned in side-by-side relationship along said cutting direction;
- a plurality of solenoid members, corresponding to each of said movable blades, for driving said movable blades linearly;
- a stationary blade for cutting the paper in cooperation with said movable blades, said stationary blade being aligned with said movable blades in spaced side-by-side relationship along said longitudinal dimension of said paper;
- and
- actuating means for actuating said solenoid members.

A cutting device, comprising:
- a plurality of movable blades for cutting paper placed in said device, said movable blades being movable linearly both forwardly and reversely along a cutting direction transverse to a longitudinal dimension of said paper, said movable blades being aligned in side-by-side relationship along said cutting direction and having a clearance therebetween;
- a plurality of solenoid members, corresponding to each of said movable blades, for driving said movable blades linearly;
- a plurality of pivotable linkage means pivotable in said cutting direction, each linkage means being connected with one of said movable blades, each of said solenoid members having a plunger means connected with one of said linkage means;
- actuating curcuit means for selectively actuating said solenid members to drive said plunger means to pivot said linkage means forwardly to move said movable blades along said cutting direction;
- a first spring means for biasing said plurality of linkage means reversely along said cutting direction to position said movable blades in a predetermined rest position;
- a stationary blade aligned with said movable blades in spaced side-by-side relationship along said longitudinal dimension of said paper, for cutting the paper in cooperation with said movable blades;
- a cover member in which said movable blades are slidably housed;
- said stationary blade having a first opening for cutting the paper and through which the paper passes;
- a spacer member interposed between said stationary blade and said movable blades and comprising means for preventing said movable blades from contacting said first opening;
- a base member having said stationary blade and said spacer member mounted thereon;
- a second spring means, responsive to forward movement in said cutting direction of at least one of said linkage means, for applying a pressure against said paper to secure said paper in position during a cutting operation;
- and
- said cover member including a second opening through which said paper passes, said second opening being disposed in aligned relationship with respect to said first opening to allow the paper to pass therethrough.
