摘要： An inkjet printing head (10) which is capable of being assembled efficiently and easily. In the inkjet printing head (10), a main frame (14) has a hollow portion (14a) for receiving a flexible cable (16) therein, and a sub-frame (22) has a rimmed window (22a) for receiving a flexible member (18). The main frame (14) and sub-frame ((22) are combined such that the flexible cable (16) and flexible member (18) are sandwiched therebetween. The hollow portion (14a) of the main frame (14), the flexible cable (16) and the rimmed window (22a) of the sub-frame (22) have the same shape so that these members can be reliably positioned with respect to one another. Electrodes (16a) on the flexible cable (16) are pressed, with a uniform pressure, to piezoelectric elements (40) of a head assembly (12) attached to the main frame (14).

摘要： A method of producing a printing head provided in an ink jet printer for jetting ink particles onto paper. A piezoelectric block is formed with a plurality of aligned curved through channels to be filled with ink. Each channel is formed with an electrode on its internal walls. Then, positive and negative voltages are applied to a pair of electrodes conforming one partition wall so as to cause a polarization of the partition wall present between the channels. A front plate having orifices for jetting the ink and a back plate having ink supply path are mounted on the front and rear sides of the piezoelectric block.

摘要： A method for driving an ink jet print head is here disclosed which is characterized by comprising the steps of carrying out printing, while a print head (1) is moved one dot at a time by 4 dots of each nozzle (2) in the print head (1) in one print scanning direction in one print line on a print paper; further repeating the printing operation 4 times in the one direction in this print line; carrying out printing, while the print head (1) is moved one dot at a time by 4 dots in another print scanning direction; further repeating the printing operation 4 times in the other direction in this print line; and then terminating one reciprocating motion of the print head (1) in the print scanning direction at a point when the print head (1) has returned to a print motion starting point. The method of the present invention permits preventing the disorder of print and the introduction of bubbles into the ink, decreasing cost, improving productivity, obtaining a high-quality print even by the use of a relatively low-density head, and smoothing a shuttle motion.

摘要： Several print chambers (2a,2b) are offset from each other in an outer region and an inner region. The print chambers in the outer region have a circumferential length which is the same as or is larger than that of the point chambers in the inner region and a radial length which is the same as or is less than that of the point chambers in the inner region. Alternatively the print chambers in the outer region and piezoelectric elements have a circumferential length which is the same as or is greater than the radial length. Alternatively the print chambers in the inner region and piezoelectric elements have a radial length which is the same as or is greater than the circumferential length.
