It has a density sensor (70) disposed between the wrapping part (4) of the cigarette maker and the cutting part (16), and the density sensor (70) detects the concentration of print information (PI) of the cigarette stick (TR). Print information (PI) is printed on the tape W by a printing unit (20) located upstream of the wrapping part (4), and is also arranged between the printing unit (20) and the wrapping part (4) to change the tape. W. Supply path length adjustment device (62). The density signal output from the concentration sensor (70) is used to control the actions of the printing unit (20) and the adjustment device (62). As a result, the concentration of the printing information (PI) and the arrival rate of the print information (PI) are respectively controlled based on the density signal ( 70) The moment. Sovereignty Item 1. A printing device of a cigarette making machine, wherein the cigarette making machine includes a wrapping portion that receives a tape and a filling material supplied along a feeding path at a prescribed speed, and uses the wrapping paper. Into the filler, a cigarette rod is manufactured, and the manufactured cigarette rod is continuously fed out; and a cutting section that cuts the cigarette rod delivered from the wrapping section at a predetermined cutting time to form a predetermined length A cigarette rod, the printing apparatus includes a printing section having a printing roller disposed in the supply path and an ink supply source for supplying ink to the printing roller, and the ink supply source for supplying ink to the printing roller should pass through the printing roller. The printing information is printed on the tape printed with the specified information on each cigarette rod; the density sensor is disposed between the wrapping portion and the cutting portion and detects each printing information on the tape. Concentration and output concentration signal; concentration control means, which controls the printing density of the print information based on the density signal transmitted from the density sensor; calculation means, which calculates the number printed on the cigarette stick The printing information should reach a time offset between the time when the density sensor was reached and the time when the density information was actually detected by the density sensor, and the calculated deviation amount was output; the timing control device, which can compensate for the time The deviation amount output by the calculation means is calculated to control the timing at which the print information reaches the density sensor.
