ABSTRACT:
A cam follower of a cam follower member of a print head is inserted into a aperture of a carriage. Next the print head is rotated clockwise 90.degree. in relationship to the carriage on the axis of the shaft. The cam follower is brought into engagement with cams provided to the interior of the aperture by rotation of the print head. As the cam follower follows the cams with rotation of the print head, the print head is pulled closer to the carriage. A plurality of contact electrodes provided to the print head are rubbingly brought into contact with corresponding counter electrodes provided to the carriage when the print head is rotated 90.degree.. An air chamber can be provided under the contact electrodes for evenly distributing between all the contact electrodes and the counter electrodes pressure applied therebetween.
