<p>PURPOSE:To make installation/demounting easy so as to simplify replacement upon maintenance by making electrification means composed of brush and the like detachable by means of a detaching device. CONSTITUTION:A threaded hole for stopped screw 31a is formed at a side plate 15a of a belt 11 laid between a conductive roller 12 serving as an electrode at the time of electrification and a drive roller. A holder 22 holding an electrification brush 21 detachably at an electrification unit 20, a hole for the stopped screw 31 and a threaded hole 36 for a locking screw are provided at a side plate 23a of the unit 20. The side plate 23a can turn freely with respect to a side plate 15a as the stopped screw 31 is inserted into the side plate 23a and engaged with the side plate 15a by means of the stopped screw 31a, while the belt 11 is electrified as the brush 21 is abutted on the roller 12 and locked by means of the locking screw. With the constitution, replacement work can be facilitated by turning the side plate 23a downward and then replacing the brush 21.</p> |
