PURPOSE:To prevent a belt running device from eccentric run of the belt using a simple configuration without provision of an eccentric run preventive guide on the belt or with no use of any complex mechanism consisting of sensor, sol. enoid, etc. CONSTITUTION:A pair of tapered rollers 28 with the dia. incremental toward the center are laid linearly to form a follower roller 22. A belt 10 is set over between this follower roller 22 and a drive roller 21, and a tension is given to the belt 10 by energizing the follower roller 22. |
