PURPOSE:To enable a head and a charge electrode to be solely attached to or detached from a head holder as well as to raise the operability of assembling and maintenance by using a system in which the head and the charge electrode can be inserted from opposite directions and assembled. CONSTITUTION:A head 25 is inserted into the left side of a head holder 26 until its small diameter portion 101 reaches the minimum diameter portion of the head holder 26 and positioned. A plate spring 27 is inserted into the groove 10 of the holder 26 and the rear side 104 of the head 25 is positioned and fixed. Charge electrodes 28 are inserted into the holder 26 from the right direction and positioned at the tiered portion, and they are fixed by the plate spring 105 serving as the terminal of charge electrodes and a plastic cap 106. |
