Claims

[Claims for Utility Model Registration] (1) A cartridge including a box-shaped carriage body with an open top and a lid that is placed over the cartridge body, and a pair of ribbon spools on the lid. The printer is equipped with a structure in which the ink ribbon is placed on the printer and sequentially feeds out the ink ribbon from one ribbon spool to the other ribbon spool as the carriage moves. It includes a locking device that is attached to the side wall surface of the main body so as to form a gap that opens vertically therebetween, and a retaining plate that has an insert piece bent downward at a substantially right angle at one end. a sensor assembly comprising a sensor substrate having a photo sensor for detecting the ink ribbon mounted on the holding plate, the sensor assembly having an insertion piece of the holding plate inserted into the gap of the locking tool; An ink ribbon detection device for a printer, characterized in that the ink ribbon detection device is fixed to the locking tool by a lid that is placed over the carriage body in the state of the ink ribbon detection device. (2) In claim (1) for utility model registration, the holding plate of the sensor assembly includes a guide block for mounting the sensor board so that the photo sensor faces the ink ribbon passing surface, and a guide block connected to the sensor board. An ink ribbon detection device for a printer, comprising a lead wire insertion hole through which a lead wire is inserted. (3) In claim (1) or (2) of the utility model registration, the sensor assembly includes a cover that presses and fixes the sensor board to the guide block and that is slidably placed over the guide block. An ink ribbon detection device for a printer, comprising: a member. (4) In claim (3) for utility model registration, the lower end of the cover member has an arrowhead-shaped engagement that can be elastically engaged with the edge of the lead wire insertion hole formed in the holding plate. An ink ribbon detection device for a printer characterized by having a protruding piece.
