Abstract: When a cut lever is rotated, a tape printer cuts a tape by using a cutting mechanism unit. The cutting mechanism unit has a cut lever rotatably supported by a lever shaft, a cutter holder provided with a cutter blade and a cutter blade receiving member. Upon rotation of the cut lever, the cut lever moves the cutter holder in a cutting direction, the cutter blade presses and cuts the tape in cooperation with the cutter blade receiving member. At a point the cutter blade comes into contact with the cutter blade receiving member, a line segment connecting a lever shaft center and a contact protrusion tangent point T becomes perpendicular to the cutting direction.

Abstract: If a top cover 5 has been opened, a link lever 34 is moved backward in conjunction with the motion of the top cover 5, so that a release lever 51 is rotated clockwise as seen from the left side about a level shaft 50. Also, a release gear 49 and a release shaft 48 are rotated about 180° counterclockwise as seen from the left side, via a lever gear 52. Accordingly, a head supporting member 37 is rotated downward, resisting an urging force of a pressing spring 36, so that a thermal head 32 is separated from a platen roller 35 and entry of a roll sheet 3A becomes possible through an insertion port 26.

Abstract: There is provided a sheet processing apparatus capable of preventing the roll sheet cut by the cutting device from falling over to the sheet processing apparatus and improving the conveyance capability of the roll sheet when the long size roll sheet is made. Long size roll sheet is fixed at three spots, wherein the three spots are the top edge portion of the roll sheet receiving portion, the top edge portion on the downstream side of the regulatory member, and the bottom edge portion of the projecting portion. The bottom edge portion of the projecting portion is constructed to be always located inside a circular arc which starts from a center O with a maximum radius R of the roll sheet, wherein the circular arc passes the top edge portion of the roll sheet receiving portion and the top edge portion on the downstream side of the regulatory member.

Abstract: A tape printer includes a holder support member at one side end in a roll sheet holder storage part in a direction substantially perpendicular to a feeding direction. In the holder support member, a mounting piece which is substantially rectangular in section and formed protruding outward on a positioning holding member of a roll sheet holder is fitted. The tape printer further includes a flat portion formed substantially horizontally between a rear edge of an insertion opening through which a roll sheet is inserted into the tape printer. On the flat portion, a front portion of a guide member is placed. At a rear edge of the flat portion in the feeding direction, at plural positions corresponding to various kinds of the roll sheets having different widths, there are formed four second positioning grooves in which part of the guide member is fitted.

Abstract: A tape printer includes a roll sheet holder storage part of which a bottom is formed with a positioning recess which is rectangular in plan view and long sideways and has a predetermined depth. A discrimination recess rectangular in plan view is provided between the positioning recess and an inner base end of a holder support member). The discrimination recess fittingly receives a sheet discrimination part extending in a predetermined length from a lower end of the positioning holding member inward at substantially right angle thereto. The sheet discrimination part is formed with sensor holes arranged in an L-shaped pattern. In the discrimination recess, there are provided sheet discrimination sensors arranged in an L-shaped pattern.

Abstract: A cutting edge of a movable blade mounted to a cutter holder is inclined at an oblique cross angle. The cutting edge of the movable blade obliquely intersects a roll sheet placed on a cutter plate in its cutting direction. This ensures that the cutting edge cuts the roll sheet sharply. On this regard, this oblique cross angle has an influence on the number of times that the cutting edge is capable of cutting. An appropriate range of the oblique cross angle is 24° and 34°. The oblique cross angle is an angle formed between an upper surface of the cutter plate and the cutting edge in the cutting direction of the movable blade.

Abstract: There is provided a tape printing apparatus capable of improving durability performance of a cutting mechanism constituted of a fixed blade and a movable blade tremendously.
