摘要： A reciprocatory dry shaver capable of driving an inner cutter smoothly along an arcuately curved outer cutter for efficient shaving. The dry shaver includes a shaving head carrying an outer cutter which is arcuately curved along its length, and an inner cutter driven to reciprocate along the length of the outer cutter. An actuator is mounted in the shaving head for driving the inner cutter. The actuator includes an oscillator which reciprocates in the lengthwise direction of the outer cutter and carries a joint for driving connection to the inner cutter. Also included in the actuator is a resilient coupling link which supports 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 one end coupled to the oscillator and the other end anchored to the shaving head at a portion away from the inner cutter than the oscillator. 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. Accordingly, the oscillator, i.e., the inner cutter carried thereon can be guided smoothly along the arc of the outer cutter, assuring smooth and efficient shaving.

摘要： An electric razor includes an actuator, an outer cutter and an inner cutter. The actuator has a first vibrator and a second vibrator. The outer cutter and the inner cutter are respectively supported at the first vibrator and the second vibrator so that the cutters can slide against each other. The actuator vibrates the first vibrator and the second vibrator so that the vibrators slide in reciprocation toward opposite directions to each other. Even though vibration of the first vibrator is interrupted by external force through the outer cutter, the second vibrator relatively vibrates so as to slide in reciprocation with respect to the first vibrator and therefore it is easy to meet specified shaving performance.

摘要： A dry shaver has a cradle head carrying shaving units as well as a motor for driving the shaving units. The cradle head is supported to a hand grip such that it is allowed to tilt about at least one tilt axis parallel to a thickness direction of the hand grip. At least one portion of the motor projects upwardly of the tilt axis, whereby the cradle head is given overall mass center which is located upwardly of the tilt axis with respect to the height axis of the hand grip. Accordingly, the motor of heavy nature can be best utilized to locate the overall mass center of the cradle head above the tilt axis for generating a torque acting to tilt the cradle head from a neutral position about the tilt axis when the hand grip is held upright.

摘要： A reciprocatory dry shaver comprises a stationary cutter, a movable cutter, and a permanent-magnet linear motor having a stator and a reciprocator which is driven by an electric current to reciprocate relative to the stator. The reciprocator carries the movable cutter to reciprocate it in shearing engagement with the stationary cutter. A power circuit is included to provided an electric power to the motor. The shaver includes a detector which detects a displacement of the movable cutter and give an output indicative of the detected displacement of the movable cutter. Also included in the shaver is a controller which varies the electric power being fed to the motor in a feedback manner based upon the output from the speed detector in order to keep an oscillation amplitude of the movable cutter at constant. In this manner, the movable cutter can reciprocate without being jammed even when experiencing a heavy lead during the shaving, thereby avoiding undesired speed reduction of the movable cutter which would result in the lowering of the cutting efficiency. Thus, the reciprocatory dry shaver is capable of keeping a constant oscillation amplitude irrespective of a lead acting on a movable cutter to thereby assure a sharp cut even when the movable cutter experiences a heavy lead during the shaving.

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 linear oscillating motor capable of assuring a consistent and effective feedback control of keeping a constant oscillation amplitude with varying load conditions. The linear oscillating motor comprises an oscillator carrying a permanent magnet, and a stator with an electromagnet. The electromagnet is supplied with an electric power to develop an electromagnetic drive force of moving the oscillator in a linear direction relative to the stator. A spring is provided to apply a restoring force to the oscillator for providing a linear oscillating motion to the oscillator. A photo-sensor monitors the linear motion of the oscillator and outputs a signal to a reverse-point detector which determines right and left reverse points of the oscillator. A controller applies the electric power to the electromagnet at the drive points respectively defined subsequent in time to the reverse points and in a varying amount for keeping a constant oscillation amplitude of the oscillator. The photo-sensor outputs a train of pulses appearing each time the oscillator passes its oscillation center. The reverse-point detector determines the reverse points based upon a time period between the two preceding pulses. Since the photo-sensor can monitor an oscillation cycle of the oscillator without being affected by the magnetic field developed by the electromagnet for driving the oscillator, it provides a reliable basis for accurately determining the reverse points and therefore the drive points. Accordingly, the driving force can be applied at an optimum timing to make the feedback control accurately and reliably.
