Abstract

PURPOSE: To increase the accuracy of resolution toward subscanning, by reading in the code of the linear encoder mounted on the rotary shaft moving the sensor section and reading out the photo sensor array with the output.
CONSTITUTION: The linear encoder 8 is mounted on the rotary shaft 19 having the rotating speed accelerated with the gear ratio of the gears 17 and 18 for the turning speed of moving roller 15 of the sensor section. The bar code of the encoder 8 is read in the photo coupler 9 and the signal is used for the readout clock of photo sensor array. For example, in accelerating with the gear ratio 2, the pitch of the linear encoder 8 is 1/2 and the similar operation can be made. Thus, the scanning speed can be kept constant and the resolution toward the subscanning can be kept excellent.
