Abstract: Provided are a slotter head, a slotter device and a box making machine comprising a cutter holder which is in a disk shape and is rotationally supported, a first cutting blade which is mounted to an outer peripheral portion of the cutter holder, a moving holder which is supported by the cutter holder movably along the circumferential direction, a second cutting blade which is mounted to an outer peripheral portion of the moving holder, a first drive device which rotationally drives the cutter holder, and a second drive device which rotationally drives the moving holder.

Abstract: Provided is an interterminal connection structure capable of eliminating the precipitate adhering to the terminal with the installation operation, securing the electrically connected state of the terminal between a pair of members, and easily accommodating to design changes in the spring load. In a cordless handset of a domestic telephone, the conductive state of the terminals employed in the electrical connection between this cordless handset and battery charger is made to contact in a mutually intersecting manner, and, in addition, the terminal on the battery charger side is made to rotate and move pursuant to the installation operation of the cordless handset, and the contact position is gradually moved while maintaining this contact state via such rotating movement. Thus, even if there is a precipitate on the terminals, such precipitate will be chipped off due to the contact movement (sliding), and a loose connection can thereby be prevented.
