Abstract
By housing a driver circuit board in a motorized roller having a built-in electric motor, the troublesome external wiring can be dispensed with, thereby facilitating the mounting of the roller on other apparatus. The heat generating inside the roller from a driver circuit board in the roller is dissipated by a heat releaser, thus protecting the devices from damage and avoiding failure of control.
