Title: Selection of number of steps of motor for closing paper holding roller
Inventor: KOBAYASHI KAZUMI
IPC: B41J35/20
Filed: 1989-11-16
Abstract: PURPOSE:To make it possible to select the appropriate number of steps best suited to the actual home position, if the mounting position of a sensor is misaligned by selecting the number of motor steppings required for the rolling in and out of a roller based on the number of return steppings using the out-of-step condition of the motor. CONSTITUTION:If a home position is misaligned, the numbers of steps Xb, Xc prestored in ROM 51 are corrected during the turning ON of a power supply. In other words, CPU 50 sets the number of steps Xc+alpha obtained by adding a fixed value alpha to a logic value Xc which is read from ROM 51, to a variable Xp on RAM 52. Next a stepping motor 11 is rotated with the interpretation of an output from the second font sensor 44 so that the stepping motor 11 becomes out of step. Then the motor 11 is rotated from this out-of-step condition in a negative direction and a counter CNT is incremented for each step. If the second font sensor 44 changes from 'ON' to 'OFF' position, the Xp is compared to the content of the counter CNT. If the comparison result indicates Xp>CNT, the actual Xc0 and Xb0 are determined by reducing the specified number of steps. On the contrary, if Xp<=CNT, the specified number of steps is added to the Xp and then the same procedure is repeated.
