Abstract: A printing section has a platen and a printhead which are oppositely located on both sides of a guide path for guiding the paper. A cutter section has a stationary blade and a movable blade located oppositely to either one of the platen and the printhead on both sides of the guide path. At the cutter section, the paper printed at the printing section is cut by engagement between the stationary blade and the movable blade. Either one of the stationary blade and the movable blade is held on a first unit located on one side of the guide path. On the other hand, either the other of the platen and the printhead and either the other of the stationary blade and the movable blade are held on a second unit which is located on the other side of the guide path. That is, the printing section and the cutter section are constructed by thus connecting the first unit to the second unit assembled as described above.

Abstract: A printer comprising a printing section that has a platen, a cutter section with a stationary blade and a movable blade and a printhead located oppositely on both sides of the guide path. A first unit is located on one side of the guide path arranged inside the casing which can be separated into a first casing member and a second casing member, holding either one of the stationary blade and the movable blade in the cutter section and a second unit located on the other side of the guide path that has either one of the other platen and the other printhead and either one of the other stationary blade and the other movable blade.

Abstract: A cutter device comprising a fixed blade and a movable blade is disclosed, the movable blade being opposed to the fixed blade and adapted to be displaced in such a manner that an engaging position thereof with the fixed blade shifts continuously. The cutter device is constructed so that the movable blade can be attached to and detached from a body of the device. Thus, attachment and detachment of the movable blade can be effected without requiring any troublesome work.

Abstract: In a novel printer and a commodity information processing apparatus of the present invention, a printing section has a platen and a printhead located oppositely on both sides of the guide path; in the printing section, a cutter section has a stationary blade and a movable blade located oppositely on both sides of the guide path and cuts paper printed at the printing section by engaging the movable blade with the stationary blade. A first unit is located on one side of the guide path arranged inside the casing which can be separated into a first casing member and a second casing member, holding either one of the stationary blade and the movable blade in the cutter section; and a second unit located on the other side of the guide path has either one of the other platen and the other printhead and either one of the other stationary blade and the other movable blade.

Abstract: A recording paper is cut such that the movable-blade holding member 17 of a resin holding the movable blade 15, which is rotatably provided in a supporting section, is driven to rotate by a drive section so as to shift a cutting position formed between the cutting edge 14b of the stationary blade 14 and the cutting edge 15a of the movable blade 15. Thereby formation of a support axis in the movable blade 15 is not needed, as needed in conventional movable blades. In addition, because the movable-blade holding member 17 folding the movable blade 15 is of a resin, it can be die-formed.
