A mold separation device includes a carrying mechanism, a scraping mechanism, and two separation mechanisms. The carrying mechanism is adapted to carry a first mold and a second mold bonded to the first mold. The scraping mechanism is disposed at an edge of the carrying mechanism and is adapted to scrape off a spilled glue produced when the first mold is bonded to the second mold. The separation mechanisms are disposed at the edge of the carrying mechanism and are located on two opposite sides of the scraping mechanism. The separation mechanisms are adapted to pull open the first mold and the second mold so that the first mold and the second mold are separated from each other.

A label die cutting device enables easily changing the shape of the die cut made in label paper. A printer 1 has a print unit 7 and a die cutting process unit 8 (label die cutting device). The die cutting process unit 8 has a conveyance path 9 for conveying the label paper 5, a die cutting unit including wire pins 41 and a wire pin drive mechanism 42 for advancing and retracting the wire pins 41, and a die cutting controller 68 for driving the wire pin drive mechanism 42 to strike the wire pins 41 against the label paper 5 on the conveyance path 9 and die cut the label paper 5 based on print data. The die cutting unit is a wire dot head 27.

A sheet processing apparatus (1) includes a first processing section (1000), a second processing section (2000), and a third processing section (3000) arranged on a straight line, and conveys a sheet (4200) therebetween. The first processing section (1000) forms a plurality of first processing lines extending in a first direction (an X axial direction) on the sheet (4200), by moving a plurality of tools (1110-1260) to the first direction in relation to the sheet (4200). The second processing section (2000) forms a plurality of second processing lines to a second direction (a Y axial direction) orthogonal to the first direction on the sheet (4200), by moving a plurality of tools to the second direction in relation to the sheet (4200). The third processing section (3000) forms a third processing line (aslant line, curve line) on the sheet, by relatively moving the sheet (4200) and the tool (3110, 3120).
