<p>The present invention provides a sheet cutter that can cut the sheet cleanly without being left uncut or torn off in cutting the sheet and is cheap and very compact by reducing the thickness of a movable knife pressure welding member. The sheet cutter comprises a stationary knife including a straight blade part formed like the straight line in the longitudinal direction, a movable knife including a cutting edge part formed in the shape of V-character, opposed to mesh with the straight blade part of the stationary knife, the movable knife being able to freely move toward or back from the stationary knife, a movable knife pressure welding member for pressure welding the movable knife against the stationary knife, and movable knife driver driving the movable knife forward or backward. The movable knife pressure welding member pressure welds the movable knife against the stationary knife by means of a compression coil spring contained inside the movable knife pressure welding member.</p> |
