摘要： PROBLEM TO BE SOLVED: To make it possible to reduce a creating time of treatment for creating a data in order to provide a treatment liquid which enhances a fixing and a waterproofing of ink by insolubilizing or aggregating a coloring matter in ink to a suitable position as to ink jet printer. SOLUTION: A treatment for creating a treating liquid data is performed in the same sequence as at treatment for temporary storing an image data and wiring back a result of HV conversion in order to perform HV conversion which converts a raster data to a column data as to an image data for printing. For example, a register 403B for creating the treating liquid data having the same constitution as a HV converting register 403A is provided. The register is masked on a pattern in accordance with the treating liquid recipe and it is corresponded to a data bit of a HV conversion register 403A at the same time. A printing data having an access to the HV conversion register is developed relative to the access and thereby the treating liquid data is created at the same time.

摘要： PROBLEM TO BE SOLVED: To implement carriage position control required for the definition of a printer irrespective of the resolution of an encoder by enabling a plurality of discriminative sensor part to be mounted in a carriage part, and also enabling a plurality of discrimination scale parts to be mounted thereon. SOLUTION: The position counter 402 controls to clear as a carriage 1 exists at a first reference position, and after the value of the position counter 402 is made '0', a carriage motor is caused to scan until a first reference and second reference sensors operate. In this way, during movement of the motor, an encoder pulse signal is counted by the position counter 402. As the second reference sensor is operated, the encoder pulse is stopped in counting by the position counter 102. The stop position is a distance from the first reference position to the second reference position, and it is decided by a place in which a sensor is installed in advance. Then, an encoder discrimination is calculated by an encoder discrimination part 62.

摘要： PURPOSE:To decrease black and white streaks and unevenness in density occurring around a place where areas of images recorded by each one of horizontal scannings adjoin each other by a method wherein a recording head is moved in the vertical scanning mode so that the second image area is partially placed on top of the first image area. CONSTITUTION:The first image area is recorded by making an ink jet recording head operated in the horizontal scanning mode. In proceeding to the recording of the second image area by making the recording head move in the vertical scanning mode after completion of the recording of the first image area, the vertical scanning is made so that ejection ports No.1-No.3 are operated in overlapping the first image area. Pixels in the area covered with the above- mentioned overlapping are applied with two times of ink jetting; namely one ink jetting per each of two scannings. The density of the pixels in the said area is controlled by total amount of ink droplets ejected thereto. Thereby black and white streaks and un-evenness in the density occurring around the place where the areas of images recorded by each of the scannings adjoin each other are considerably reduced.

摘要： PURPOSE:To obtain a stable output even if a tuning fork resonance frequency is varied by providing a 2nd filtering means which has the same characteristics as that of a 1st filtering means between a piezoelectric element for drive detection and a synchronizm detecting means and making the gain of a synchronizm detection signal constant. CONSTITUTION:Piezoelectric elements 15 and 16 for detection detect the angular velocity by multiplying the vibration speed of an X-directional resonance frequency by the input angular velocity and an amplifier 29 outputs detection voltages from the elements 15 and 16 as an amplification detection voltage. The signal from a BPF 30 is detected synchronously by a synchronous detecting circuit 31 based on the movement voltage from a phase shifting circuit 28 to generate a synchronizm detection signal. Namely, the circuit 28 shifts the signals from the piezoelectric elements 13 and 14 for drive detection in phase by 90 deg. and the synchronizm detection signal is proportional to the angular velocity. Further, only the low frequency component of the synchronizm detection signal passes through an LPF 32 and is outputted by an output amplifying circuit 33 as a voltage matching the system.
