ABSTRACT:
In the position detection device, a timing fence is formed with a plurality of slits which are arranged in its elongated direction. An elongated metal member is provided for supporting the timing fence so that the timing fences will extend in the scanning direction of the image recording head. An encoder is provided for counting the slits on the timing fence while the carriage moves. A gap between the encoder and the elongated metal member can be adjusted properly and uniformly through rotating eccentric collars of the adjustment members inserted into the elongated through-holes in the elongated metal member.
