  • Publication number: 20020174546
    Abstract: An electric rotary shaver including a cutter retaining plate equipped with cutter units each having an inner cutter and an outer cutter and detachably attached to an outer cutter frame of the shaver, and the shaver further including an attachment-detachment mechanism for mounting the cutter retaining plate to the outer cutter frame in a detachable fashion. The attachment-detachment mechanism includes a triangular boss and an engagement projection. The triangular boss is formed on the outer cutter frame and has engagement openings opened in its side surfaces, and the engagement projection is formed on a mounting knob held in cutter retaining plate. By turning the mounting knob with its engagement projection inserted in the boss and thus letting the engagement projection be engaged with the engagement opening, the cutter retaining plate is mounted to the outer cutter frame of the shaver in a detachable fashion.

  • Patent number: 5920988
    Abstract: An electric shaver including a display that indicates when it is time to clean the shaving debris accumulated on a shaving debris receiving part that is covered by an outer cutter frame of the shaver. A counting device of the shaver counts the use time (or the load current) of the motor that drives the inner cutter so that a control device compares the counted use time with a preset reference value; and when the counted use time reaches the preset reference value, the control device judges that the time for cleaning has arrived and actuates the display so that the display shows that it is time for cleaning. Thus, the user detaches the outer cutter frame and removes the shaving debris from the shaving debris receiving part in which a light-receiving devices is embedded.
