A printer has a roll of a paper and a cutter. The cutter includes a stationary blade provided and a movable blade. The movable blade is movable in an up-down direction with respect to the stationary blade between a first position and a second position. The stationary-side cutting tooth is located at a position higher than a guide surface. The movable-side cutting tooth is located, with respect to the guide surface, at a lower position when the movable blade is located at the first position, at a higher position when located at the second position, and at a third position, which is between the first and second positions, when the roll is attached to an accommodating part of the printer. When located at the third position, at least a part of the movable-side cutting tooth is located at a higher position than the lower end of the guide surface.

A cutting device for cutting a food product that is conveyed by a conveyor means. The cutting device includes a first cutting blade and a moving mechanism attached to the first cutting blade for moving the first cutting blade sideways in either direction across the conveyor means, and a control unit. The first cutting blade is adapted to cut at least one incision in the product from one side of the product. The control unit is adapted to control the first cutting blade and the moving mechanism based on image data of the food product, and includes utilizing the image data in instructing the moving mechanism to adjust the position of the first cutting blade across the conveyor means.

A slit-cutting device includes a first holder, a second holder, a first contactable member a second contactable member, and a protrusion member. The first holder includes a medium faceable area and a first contactable member. The second holder holds a blade and includes a second contactable member. A cutting edge of the blade may cut a medium between the first holder and the blade. The first contactable member and the second contactable member contact each other and defined a closest approach distance between the cutting edge and the first holder. The closest approach distance is longer than zero and below a thickness of the medium. The protrusion member protrudes more than the closest approach distance from a part of the medium faceable area. The cutting edge may make a cut line includes at least a part of a slit-cut and a full-cut in a cutting edge direction in the medium.

A cutter-used index assembly includes a cutting board, a pointer and at least one spring-biased detent. The cutting board includes at least one group of positioning bores and at least one groove in communication with the positioning bores. The groove is made with a diameter smaller than that of the positioning bores. The pointer is pivotally connected to the cutting board and includes at least one pointing tip. The pointing tip includes an aperture. The aperture includes an upper open end and a reduced lower open end. The at least one spring-biased detent includes comprising a ball inserted in the aperture and formed with a lower portion located out of the aperture. The lower portion of the ball is smoothly movable into one of the positioning bores from another along the groove.

A power tool (1), such as a multi-tool, includes: a motor (21) extending in a front-rear direction; a motor housing (2) that houses the motor (21); a head housing (7) held forward of the motor housing (2); and an output shaft (60) protruding downward from the head housing (7). The head housing (7) may be made of a resin. In addition or in the alternative, the head housing (7) includes a lower-head housing case (4) screw fastened to an upper-head housing cover (5). In addition or in the alternative, the motor housing has a two-halved structure in which two half housings (2a, 2b) are screw fastened together.

A cutting device, including a rotating body, a first link member, a second link member, a placement part, and a movable blade holder, is provided. The first link member is swingable by rotation the rotating body. The second link member is swingable by the movement of the first link member. The movable blade holder is swingable by the movement of the second link member between a cutting position and a retracted position. The rotating body is located sideward from a basal end portion of the movable blade holder, the motor is located sideward from a center of the placement part, a swing axis of the second link member is located sideward from the second end of the placement part, and the first link member is located between the second link member and the rotating body, sideward from the center of the placement part, in a predetermined orientation.

A cutting device, including a rotating body, a first link member, a second link member, a placement part, and a movable blade holder, is provided. The first link member swings according to rotation of the rotating body, and the second link member swings according to swing movement of the first link member. The movable blade holder swings according to swing movement of the second link member and includes a basal end portion, a distal end portion, and an attachment portion, on which a movable blade to cut a printing medium is attached. The movable blade holder is configured to swing between a cutting position, at which the printing medium is nipped between the movable blade and the placement part to be cut by the movable blade, and a retracted position retracted from the cutting position.
