Abstract: PURPOSE:To surely prevent that a top board is assembled in a state where a heater board is slipped out of a fixed position in the assembling process of an ink jetting head. CONSTITUTION:When a top board 104 having a nozzle hole 104 formed corresponingly to each heater 112 is assembled on a heater board 102 provided with plural number of heaters 112, the heater 112 on the heater board 102 is photographed. A recognition mark to indicate a heater to be the standard is confirmed on photographed image information, and the position of the heater to be the standard is measured. Plural number of nozzle holes including the nozzle hole to be the standard corresponding to the above position of the heater are photographed, and the position of the nozzle hole to be the standard is measured on the photographed image information. The heater board or the top board is moved on the result of the above measurements so that the heater and the nozzle hole which are to be the standard may coincide in the vertical direction.

Abstract: PURPOSE:To enhance computing accuracy by computing a calibration distance as the quantity of dislocation between the optical axes of a first and a second camera based on the difference between a first distance from a reference line to the reference point of a calibration member and a second distance from the reference line to the reference point of the aforesaid calibration member. CONSTITUTION:Each calibration reference point 78d of calibration charts 78 is made to coincide with an assembly work position alpha. Each calibration chart 78 is photographed by the use of both of the first ITV camera 40g of a first position detection mechanism 40 and the second ITV camera 42g of a second position detection mechanism 42. These images are transferred to an image processing device via a first signal converter and a second signal converter respectively. And a distance x1 from the left end of a figure to the calibration reference point 78d is electrically measured based on the image photographed via the first ITV camera 40g, and a distance x2 from the left end of a figure to the calibration reference point 78d is electrically measured based on an image photographed via the second ITV camera 42g. And the value of x1-x2 shall thereby be made to be the quantity x of dislocation.

Abstract: PURPOSE:To maintain the first and the second members in a specific condition and to prevent a slippage of position by irradiating ultraviolet rays to an adhesive placed between the first and the second members in the pressure-contact state of the first and the second members with each other, in a pressure-contact process. CONSTITUTION:To the surface to be bonded of the first member 102, an adhesive 80a of an ultraviolet-ray hardening property is applied. Then the first member 102 is placed on a joining force generating means 34. The first and the second members 102 and 104 are unified in respect of the X-axis direction and the Y-axis direction each other, one member 102 of the first and the second members 102 and 104 is moved in the Z-axis direction facing the other member 104, the joining force is generated in the joining force generating means 34, and both members 102 and 104 are pressure-contacted. Under the condition of the first and the second members 102 and 104 being pressure-contacted with each other by the pressure-contact process, the ultraviolet rays from a light source 58 is irradiated to the adhesive 80a placed between the first and the second members 102 and 104.

Abstract: PURPOSE:To make possible the ink in a nozzle to be refreshed when recording is started again, even though the stopping time of the recording is long, by setting a preliminary delivery timing at a point of time where a distance from the inside surface opposite to an ink delivery opening of a cap is larger than a capping time. CONSTITUTION:A preliminary delivery timing is set at a point of time where a distance from the inside surface opposite to an ink delivery opening 8 of a cap 14 to the delivery opening 8 is larger than a capping time, when a stabilization of a delivery character is contrived with a preliminary delivery is carried out before a recording in the case of the recording is started again. In accordance of this manner, the ink in a nozzle can be refreshed and an inferior delivery can be prevented from to be produced even though when a recording is stopped for a long time, since the preliminary delivery against the cap can be carried out directry before the recording is started again.
