摘要： An optical measuring device measures optical characteristics of an object in a non-contact state. The optical measuring device has a light source that illuminates an object surface, a light receiver that receives a light beam reflected from the object surface, and a light-regulating member that regulates an illuminating light beam radiated onto the object surface and the reflective light beam reflected from the object surface. The light-regulating member has a first light-regulating member that determines at least one of an illuminating region and a reflective region with respect to the object surface, and a second light-regulating member that determines a region where the reflected light beam that is reflected from the object surface and is incident on the light receiver is measured on the object surface.

摘要： In an inkjet printing device, at least two kinds of drive waveforms are selectively fed to each of plezoelectric elements for controlling an injection amount of ink to be jetted toward a print medium via a corresponding nozzle. One of the drive waveforms is in the form of a cardiac waveform which has two voltage changing points in one drive period thereof. At the voltage changing point, a sign of slope of voltage variation is inverted. In the cardiac waveform, a voltage at one of the voltage changing points is set lower than a standby voltage, while a voltage at the other voltage changing point is set higher than the standby voltage.

摘要： Disclosed is a method of driving a piezo-electric type ink jet head for jetting inks out of a nozzle by making use of a distortion of a piezo-electric element. The driving method includes a first step of driving the piezo-electric element so that a meniscus of inks is receded from an initial position of the nozzle to a first position within the nozzle, a second step of driving the piezo-electric element so that the meniscus quickly advances from the first position to a second position within the nozzle, and a third step of driving the piezo-electric element so that the meniscus slowly advances from the second position to the initial position. A particle quantity of ink particles is changed by changing a movement quantity from the first position to the second position in the second step.
