Attachment-engaging portions are formed on the respective lids and disposed longitudinally of the cylinder to face outwards so that the portions and the cylinder rotate together. The portions have axes arranged offset with respect to axes of the shafts. The shafts are held in position in and by an immovable part, with the attachment-engaging portions being not only connected to the frame but also capable of rotating relative to the frame.

摘要： Object of the present invention is to distribute signals indicating angular position of a rotor from a controller for a brush-less motor to another control device. A controller for driving a brush-less motor has a magnetic-pole detecting circuit (9) that receives from a Hall-effect semiconductor disposed in a motor roller (4) sequential (pole position-representing) signals relating to a rotor's position. These signals are converted into pulses and then supplied to a current-controlling circuit (8), so that currents to stators are controlled based on the signals from the detecting circuit (9) so as to drive the motor roller. A sequencer (20) supplies to a controlling circuit (7) “ON/OFF” and other commands, that are then processed in this circuit and fed to the current-controlling circuit (8) for driving the motor. A pulse generator (19) receives from the semiconductor the pole position signals and convert them into pulses, that are then output to an external terminal (11a) from which they are sent to a superordinate external controller, so that the latter can receive rotation data from the brush-less motor controller.

摘要： A conveyor system is divided into a plurality of zones each including a plurality of rollers arranged in parallel with each other. The zones are arranged successively for conveying articles from the upstream end to the downstream end of the conveyor system. One of the rollers in each zone is a drive roller. Article detectors are disposed in association with the respective zones and develop an article-representative signal when they detect an article in the associated zones. A current detector detects the sum of currents flowing through motors driving the drive rollers and develops a excessive-current representative signal when the sum current exceeds a reference current value. A current suppressing circuit connected to the article detectors and to the current detector causes limited currents to be supplied only to motors including the motors in the zones where the first and second in order ones of articles being conveyed are present. The limited currents supplied to the motors are such that the sum is equal to a predetermined allowable value.
