SOLUTION: Two ink chambers 114a and 114b individually provided for one nozzle 118 and piezoelectric elements 116a and 116b corresponding to the ink chambers 114a and 114b are provided. A drive signal for ejection is applied to the piezoelectric element 116a, and an assisting voltage drive signal is applied to the piezoelectric element 116b from a head controller 14. The drive signal for ejection includes, in the described order, a voltage waveform for generating pressure for adjusting a meniscus position in the nozzle 118 and a voltage waveform for generating pressure for ejecting an ink droplet from the nozzle 118. The assisting voltage drive signal includes a third voltage waveform for generating pressure for suppressing the generation of small ink droplets accompanying ejection of the ink droplet in accordance with a fall of a second voltage waveform.

Abstract: PROBLEM TO BE SOLVED: To provide a recording head for an ink-jet printer by means of which ink droplets can be stably injected. SOLUTION: This invention relates to a recording head for an ink-jet printer. In this case, ink droplets are injected from a nozzle part 1. In addition, an ink room 3 feeds ink to the nozzle part 1. In addition, a piezoelectric element 5 provides a positive or a negative pressure to the ink 2 in the ink room 3 by changing the vol. of the ink room 3. In this case, the piezoelectric element 5 generates a pressure within such a range that does not inject the ink droplets from the nozzle part 1 and then, generates a pressure for injecting the ink droplets from the nozzle part 1.

Abstract: PROBLEM TO BE SOLVED: To provide an ink jet printer in which generation of satellite drop can be suppressed, and a recording head driver and a driving method for ink jet printer. SOLUTION: Two piezoelectric element 116a, 116b are provided for each ink chamber 114 corresponding to a nozzle 118. The element 116b on the nozzle side is displaced previously in the contracting direction of the ink chamber. Under that state, the supply side element 116a is displaced in the contracting direction of the ink chamber to start jetting of ink drop and then the other element 116b is displaced in the expanding direction of the ink chamber to generate a negative pressure in the ink chamber 114. Consequently, the tail of an ink drop is pulled back and made thin and thereby it is cut quickly. According to the arrangement, generation of a satellite drop can be suppressed.

Abstract: PROBLEM TO BE SOLVED: To provide an ink jet printer in which the jetting period can be shortened by suppressing residual vibration of meniscus after jetting an ink drop, and a recording head driver and driving method for ink jet printer. SOLUTION: A piezoelectric element 116 is provided for the ink chamber 114 of a nozzle 118 and displaced in the contracting direction of the ink chamber thus jetting an ink droplet. A characteristic vibration takes place in the element 116 after an ink drop is jetted and a meniscus (forward end part of ink) undulates at a long period. The element 116 is then displaced in the direction for suppressing the long period vibration of the meniscus at a specified timing thus suppressing the long period residual vibration of the meniscus. According to the arrangement, effect of jetting operation on to next jetting operation can be suppressed even if the jetting interval of ink drop is shortened and the jetting period can be shortened without sacrifice of print quality.

Abstract: PROBLEM TO BE SOLVED: To achieve various expressions accurately by jetting ink droplets by driving signals with different wave forms. SOLUTION: A wave form selecting part 141-1 selects any of a plurality of driving signals 145-1 to 145-N from a driving wave form generating part 142 by time sharing based on a wave form selecting signal 146-1 from a driving wave form selecting control part 143 so as to supply it to a piezoelectric element of the corresponding nozzle. Accordingly, the jetting control of ink droplets can be conducted by wave form driving signals different according to the time. The driving signals 145-1 to 145-N also include a driving signal with a predetermined wave form, which is not a certain voltage wave form but cannot have ink droplets jetted by itself. According to the time sharing selection not only per the jetting cycle but also within the jetting cycle, a new driving signal wave form can be synthesized. The other wave form selecting parts 141-2 to 141-n operate in the same manner.

Abstract: PROBLEM TO BE SOLVED: To enable faithful expression of halftone and correction of irregularities in ink droplet discharge characteristics among nozzles. SOLUTION: Waveform selection sections 141-1 to 141-n select one from multiple driving signals 145-0 to 145-N outputted from the driving waveform generation section 142 on the basis of waveform selection signals 146-1 to 146-3 and supplies selected driving signals to piezoelectric elements provided for multiple nozzles, respectively, to discharge ink droplets, making it possible to vary the size of all ink droplets discharged simultaneously from the nozzles for all nozzles.

Abstract: PROBLEM TO BE SOLVED: To easily print a large number of images in a short time and at a low cost by omitting the development, sticking and lamination treatments, etc., of a photo of the upper half (face) of a human body in an image print process. SOLUTION: This device has a host computer 23 which composites the 1st signal inputted from a CCD camera 20 that converts an optical image into the image signals with the 2nd image signal, a filing device 25 which supplies the image signals to the computer 23 and a recording part which records the inputted image signals. The image signals are supplied to the computer 23 in response to a read request of the computer 23. The composite image signals produced by the computer 23 are printed on an image print adhesive sheet having a base part including a print face on one of its both sides and a separate paper stuck to the other side and also has a cut area which is formed by cutting the print face and the base part in a desired shape.
