A cutting apparatus includes a platen receiving an object to be cut, a carriage with a cartridge holder to which a cutter cartridge is detachably attachable and a pressing unit located on the carriage or the cartridge holder and switchable between a fixing position and an open position. The cartridge holder is formed with an opening through which the cutter cartridge is inserted and has an abutted portion against which an abutment abuts and which is a receiving portion having a tapered surface contacting with at least a part of the abutment. The receiving portion includes a plurality of elastic portions and a blocking portion. The blocking portion controls a position of a casing of the cutter cartridge. The casing abuts against the blocking portion when the cutter cartridge is inserted through the opening and the cartridge holder and the pressing unit is switched to the fixing position.

A cutter, detachably attachable to a support member, includes a shaft made of a resin and has a smaller-diameter portion and a larger-diameter portion formed integrally with the shaft. The smaller-diameter portion is rotatably supported by a plurality of bearings. The larger-diameter portion has a proximal end surface abutting on an end surface of one of the bearings, with a result that the cutter is locked. The cutter includes a flat blade located on a distal end of the larger-diameter portion. The cutter includes a metal member which can be attracted by a magnet located on the support member. The metal member is located on a distal end of the smaller-diameter portion. Contact portions are located on axially differing portions of the shaft respectively and are capable of contacting the bearings respectively. Thinned parts are located between the contact portions and extend in the axial direction of the shaft.

A cutter, detachably attachable to a support member, includes a shaft made of a resin. The cutter has a smaller-diameter portion and a larger-diameter portion formed integrally with the shaft. The smaller-diameter portion is rotatably supported by a bearing located on the support member. The larger-diameter portion has a proximal end surface abutting on an end surface of the bearing, with a result that the cutter is locked in a state where an axial position of the cutter relative to the support member is immovable. The cutter includes a flat blade located on a first end as a distal end of the larger-diameter portion. The flat blade cuts an object to be cut. The cutter includes a metal member which can be attracted by a magnet located on the support member. The metal member is located on a second end as a distal end of the smaller-diameter portion.

An illumination device for a multineedle sewing machine includes an illuminating member which has a light source and located at a lateral side of a needle bar case and is disposed so as to open portions of needle bars and portions of needles, a light amount adjusting unit which adjusts an amount of light of the light source, and a control unit which controls the light amount adjusting unit with movement of the needle bar case by the needle bar case moving mechanism together with the illuminating member so that a predetermined illuminance is maintained at least in part of an illuminated area which is illuminated by the light source. The part of the illuminated area is located near the needle drop position.
