PROBLEM TO BE SOLVED: To provide a liquid discharging cartridge and a liquid discharging apparatus which enable printing of a superior image quality without color density unevenness by suppressing feeding unevenness of a liquid to discharge openings and stabilizing a liquid droplet amount discharged from the discharge openings. SOLUTION: Wave motion absorbing parts 53 are set at both ends 52a in a longitudinal direction of an ink passage 52. Generation of standing waves in ink (i) within the ink passage 52 can be prevented, so that the generation of pressure unevenness to the ink (i) in the ink passage 52 is prevented. A proper amount of the ink (i) is discharged from a nozzle 62a of an ink liquid chamber 64 to which the ink (i) of a suitable amount not too much and not insufficient is supplied. Printing of the superior image quality without color density unevenness is enabled accordingly. COPYRIGHT: (C)2005,JPO&NCIPI

PROBLEM TO BE SOLVED: To improve the production efficiency, by rotating a working table at a specific angle just before one step of the position the working table is rotated one round, in a specific rotation direction as the angle made by neighboring working positions each other to the center of the working table, and after that, rotating at a specific angle in the reverse direction. SOLUTION: On an index table 8, position regulating working units 14, 15, and 16 are provided at the interval 120 deg. in the rotating direction θ, and after the index table 8 is rotated two rounds at 120 deg. in the regular direction, the rotating operation 240 deg. in the reverse direction is repeated, in the working condition. As a result, since the working can be carried out in the processing order to laser couplers 2 held on loading tables 11A, 11B, and 11C respectively, without leaving working units 17, 18, and 19 uselessly, the time from the time when one laser coupler 2 is manufactured to the time when the next laser coupler 2 is manufactured can be reduced.
