Abstract: A printing apparatus includes a first and a second housing parts, a printing part, and a conveying part which includes a holding part that holds a first paper sheet and a second paper sheet in an overlapped state and respectively pulled out from a first paper roll and a second paper roll, and conveys the first paper sheet out of the first paper sheet and the second paper sheet held by the holding part to the printing part. The holding part includes a contacting member contacting the second paper sheet out of the first paper sheet and the second paper sheet in an overlapped state, and an opposing member arranged opposing the contacting member and contacting the first paper sheet. A first frictional force between the contacting member and the second paper sheet is larger than a second frictional force between the opposing member and the first paper sheet.

Abstract: A printer includes a first housing part, a second housing part, a printing part that prints on the first paper sheet and the second paper sheet, a conveying part that includes a holding part that is configured to hold the overlapping first paper sheet and the second paper sheet respectively pulled out from a first paper roll and a second paper roll, and conveys the first paper sheet out of the first paper sheet and the second paper sheet held by the holding part to the printing part, a first paper sheet sensor that detects the presence of the first paper sheet, and a controlling part that makes the conveying part convey the second paper sheet held by the holding part to the printing part when the first paper sheet sensor detects that there is no first paper sheet to be conveyed to the printing part.

Abstract: A sheet cutter includes: a stationary knife including a straight blade part formed in a straight-line shape in a 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 pressing member for pressing the movable knife against the stationary knife; and a movable knife driver driving the movable knife forward or backward. The movable knife pressing member pressure contacts the movable knife against the stationary knife by a compression coil spring contained inside the movable knife pressing member.

Abstract: 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.
