At this time, the third linear motor 16 moves downward so that the bottoms of the two electrode columns 14 are inserted into the inner side of the group of detection holes 9 and touch the patches of the electrode sheets for two seconds. Then the third linear motor 16 returns to its original position. Then the second linear motor 15 drives the electrode columns 14 to move in the Y-axis direction to directly above another group of detection holes 9 and moves down again. The electrode columns 14 are inserted into the inside of the group of detection holes 9 for two seconds.

After the detection is completed, the second linear motor 15 moves in the opposite direction so that the electrode column 14 is located directly above another group of detection sockets 9 in the column. After the detection is completed, the first linear motor 5 moves again so that the bottom of the electrode column 14 is located directly above a group of detection sockets 9 in the next column. This process is repeated and the above operation is automatically performed until the last group of detection sockets 9 is detected and stopped. At this time, the reset button 3 is pressed, and the first linear motor 5, the second linear motor 15 and the third linear motor 16 return to the initial position.
