摘要： In a reciprocation type electric shaver having an outside blade unit detachable from a main body, the outside blade unit comprises a main blade, a slit blade and an outside blade holder for holding the main blade and the slit blade capable of floating up and down. A coupling structure for coupling the slit blade on the outside blade holder has a retaining structure for engaging the slit blade and the outside blade holder in a lateral direction of the outside blade unit so as to prevent disengagement of the slit blade from the outside blade holder when the slit blade is floated up and down with inclination. The retaining structure is a pair of fitting recesses formed on the slit blade and a pair of fitting protrusions formed on the outside blade holder.

摘要： An electric shaver is provided which can enhance the vibration sound by increasing the length of arch-like edges formed between adjacent slots of the inner blade. In the electric shaver, an inner blade having the arch-like edges is moved reciprocally while its outer face contacts with and slides over an inner face of an outer blade to cut beard. The inner blade has an arch-like plate member, as a main body of the inner blade, and it has slots extending from a side wall through a top curved portion to the other side wall, to form arch-like edges between adjacent slots, and the inner blade is connected through a joint to a driver of the main body to be moved reciprocally. Mounting members for the joint are provided at two ends of the inner blade in the longitudinal direction, and the lower ends of the edges at the central portion of the inner blade are set lower than the lower ends of the beads formed above the mounting members of the inner blade.

摘要： A reciprocating electric shaver (1) is provided. This reciprocating electric shaver (1) includes a main body block (8) and a head block (10), the head block (10) having four rotary connecting portions (32) at the front and the rear positions on the upper left and the upper right ends, the main body block (8) having four head support members (37), each of which can move up and down independently, and head floating springs (44) biasing upward each of the head support members (37) for floating, each of the head support members (37) of the main body block (8) being connected at the upper ends with each of the four rotary connecting portions (32) in a manner such that the head block (10) can rotate back and forth about the transverse direction of the shaver, thus allowing the head block (10) to rock back and forth relative to the main body block (8). As a result, even when the head block (10) is pressed against a skin with a small force, the head block (10) can excellently rock back and forth to conform to the contour of the skin.

摘要： A reciprocatory dry shaver has a shaving head carrying an outer cutter, and an inner cutter. An actuator is mounted in the shaving head for driving the inner cutter. The actuator includes an oscillator which carries a joint for driving connection to the inner cutter. Resilient coupling links are provided to support the oscillator to the shaving head in order to allow the oscillator to reciprocate relative to the shaving head. The resilient coupling link has its upper end coupled to the oscillator and has its lower end which is farther away from the inner cutter than the oscillator and is anchored to the shaving head. Thus, the oscillator is supported as being floated or lifted with respect to the shaving head, thereby being allowed to travel along a path which is somewhat arcuate in coincidence with the arc of the outer cutter.

摘要： A reciprocating electric shaver including a main body, plural blade cassettes and a retainer. Each of the plural blade cassettes includes an outer blade and an outer blade frame to which the outer blade is attached. The outer blade frame has engaging members at end portions in a longitudinal direction substantially perpendicular to an arranging direction of the plural blade cassettes. The plural blade cassettes are attached to the main body via the retainer. The retainer has a pair of end walls substantially parallel to the arranging direction. Each of the pair of end walls has slits extending along a floating direction substantially perpendicular to the longitudinal direction and to the arranging direction. The retainer retains the plural blade cassettes substantially in parallel each other by introducing the engaging members into the slits respectively such that each of the plural blade cassettes is independently movable along the floating direction with respect to the main body and such that the outer blade frame of each of the blade cassettes covers an outer periphery of the retainer.

摘要： A reciprocatory dry shaver has a head from mounting three elongated cutter heads, one center cutter head and two outer cutter heads extending in parallel with each other. Each cutter head comprises a holder carrying a stationary cutter and a movable cutter driven to reciprocate in shearing engagement with the stationary cutter. The head frame is mounted on a shaver housing from which a reciprocating element projects to drive the movable cutter of each cutter head. The center and outer cutter heads are floatingly supported at individual longitudinal ends by associated center and outer spring members so that each cutter head is vertically movable relative to the head frame. The center spring members are formed in one of the head frame and the associated holder while the outer spring members are formed in the other of the head frame and the associated holders. Thus, the spring members for floatingly supporting the center and outer cutter heads can be effectively distributed to the head frame and the associated holders to enable compact arrangement for a system of floating supporting the three parallel cutter heads within a limited space.
