Patent ID: 7605833

Claim:
A writing device to write an image onto a photoconductor, comprising: a print head including a plurality of LEDs, arranged above and across a width of a photoconductor, which forms an electrostatic latent image on the photoconductor, and the print head including an engaging hole; a first supporting member, including a position determining section which engages the engaging hole to determine a position of the print head against the photoconductor, and an adjustment screw which adjusts a position of the position determining section mounted on the first supporting member, the adjusting screw being capable of being locked after the position of the print head is determined; and a second supporting member which is engaged with the first supporting member by the adjustment screw, including a reference shaft mounted in parallel to the adjustment screw on the second supporting member and positioned for coming into contact with the first supporting member to movably support the first supporting member in a direction in which the print head moves to or separates from the photoconductor, and a pressuring member which presses the reference shaft against the first supporting member, wherein a first direction, defined parallel to a face of the first supporting member and extending along a first line through the position determining section and the adjustment screw, forms a right angle with a second direction, defined parallel to the face of the first supporting member and extending along a second line through the adjustment screw and the reference shaft that is offset from the adjustment screw.
