<p>PURPOSE:To obtain a recording density varying type recording device by which excellent recording operation can be performed in correspondence with uses and wherein the light emitting timing of an LED and the amount of movement of an optical writing head in the secondary scanning direction are controlled in correspondence with moving inclination of an LED array, respectively. CONSTITUTION:An LED array 9 is provided so that it is freely moved and positioned with the optical axis of an image forming lens 10 in an image forming optical system as a center. In correspondence with the moving inclination, the light emitting timing of the LED and the amount of movement of an optical writing head 4 in the secondary scanning direction are controlled by varying means, respectively. The constitution is simplified without the effect on the image forming optical system and multiple stage high density can be readily obtained. At the time of graphic recording, high density recording can be performed; and at the time of character recording, high speed recording can be performed.</p> |
