PROBLEM TO BE SOLVED: To simplify the structure and to make electrical connection efficient by fitting a power receiving compression coil spring to the lower end of a whole width erasing head assembly without using a power feeding connector. SOLUTION: A pin 64 is projected from the lower end of a head 62 toward a main printed circuit board 2, and is inserted into a fixing hole 72, so that the whole width erasing head assembly 60 is fixed to a base 70. A through hole 66 is formed in a part extended laterally at one side of a lower part of the head 62. Moreover, a terminal 2a led from a power source (not shown in the figure) is provided on the main printed circuit board 2 in a position opposite to a connecting hole 1a. A connecting member 100 is made of an electrically conductive material, and is projected from the lower end of the head 62 toward the main printed circuit board 2, so as to function as the electrical connection of the whole width erasing head assembly 60 to the terminal 2a on the main printed circuit board 2 through the connecting hole 1a. |
