Abstract: A master tape and a slave tape are driven so that successive portions of each are brought into substantial contact with successive portions of the other at a printing station. A printing magnetic field is applied to such successive portions while they are in substantial contact with each other at the printing station, so that data on the master tape is copied onto the slave tape and the slave tape becomes a copy of the master tape. A single master tape can thus be employed to produce a plurality of copies. A counter counts the number of copies thus produced, and an indicator provides an indication corresponding to the remaining life expectancy of the master tape.

SOLUTION: A printing head of a carrier jet system printer is composed of a pressure chamber unit having pressure chamber 40, 41, and first and second piezo units corresponding to respective pressure chamber 40, 41. The pressure chamber unit is composed of an orifice plate 38 on which inductive openings 35, 37 communicated to nozzles 34, 36 are formed, the pressure chamber 40 being a passage for diluting liquid, the pressure chamber 41 being the passage of ink, and a diaphragm 42. In this case, a groove part 63 is formed over from the opening part of the nozzle 66 (36) of one main surface 68a being a nozzle opening surface of the orifice plate 68 (38) to the opening part of the nozzle 64 (34). Thereby, sticking of ink to around the nozzle opening part is inhibitted.

Abstract: PURPOSE:To effectively obtain a high resolution in a subscanning direction without varying the moving direction of a photosensitive body by using plural laser elements as a light source and shifting the peak position of a laser spot by the composition of their outputs. CONSTITUTION:As a hexagonal mirror 8 rotates, the spot position shifts 1 from a point A to a point B on a photosensitive drum 1, and consequently, one scanning line is drawn. Then, the photosensitive drum 11 is rotated in a specific direction to draw lines in order, thereby forming one image called an electrostatic latent image. This latent image is visualized by a developing device, transferred to paper and fixed, and then outputted. Here, what is called a multi-beam element formed by integrating the laser elements on one chip is utilized as a laser unit; and the lasers are turned on at the same time and their powers are properly controlled to shift the peak of the composition output to an optional position in the laser array.

Abstract: PURPOSE:To simplify a copying operation by detecting the rotational number of a counter roll which is revolved in response to the tape driving speed as well as the rotational number of a supply reel for slave tape and at the same time detecting the thickness of the slave tape to know an amount of the remaining tape at the supply side. CONSTITUTION:Both start and end cue signals of a master tape MT are detected by a reproduction head 21 when the 1st copying action is carried out to a slave tape ST. A CPU25 knows the recording time Lo of a program from the number of pulses given from an FG23 and records it. At the same time, the thickness of the ST is obtained from the program time and stored. Then both the MT and a drive tape DT are rewound to perform the 2nd copying job. The CPU25 calculates the wind diameter of the remaining ST from the rotational number Nc of a supply reel of the ST, the rotational number Mk of a counter roll 22 and the pulses supplied from both FG 23 and 24. Then a remaining tape amount L is calculated from the limit wind diameter of tape and the thickness of the ST. Thus the remaining copy amount is displayed on a display device 24 through the calculation of L/Lo.
