PURPOSE:To make it possible to know constantly the optimum state of cleaning, by providing an abrasive which conducts cleaning while moving in contact with a line of exposed pin electrodes, and a device which is fitted to a holder supporting the above abrasive and measures the reflection density of an electrode member which is cleaned. CONSTITUTION:A holder 35 is moved in parallel along pin electrodes 9 on a multineedle electrode head 2 by a guide roll 21, while a rubber abrasive 36 depresses the ends of the pin electrodes 9. The rubber abrasive 36, rotated by a motor 37, cleans the ends of the pin electrodes 9. At this time, the reflection density of the pin electrodes 9 is read by a light-emitting/light-receiving element fitted to the holder 35, and when the cleaned state is excellent, a reflection factor above a certain value can be obtained. |
