The operation of this counter device is such that when the switch handle 10 is rotated from OFF to ON, the switch protrusion 37 moves from the solid line to the imaginary line as shown in FIG.
1 is pushed by the switch protrusion 37, bends the spring part 82 and rotates as shown in the imaginary line, and as a result, the claw 83
rotates and engages with the groove of the ratchet wheel 79, and rotates by one thread of the ratchet wheel 79. This rotation of the ratchet 79 causes the gear 7
8 and 71 rotate, and the display board 67 rotates. As a result, the color display portion 72 appears at one end of the display slit 65 on the surface of the base 58, and moves onto the display slit 65 by one scale corresponding to one use. When the switch handle 10 is turned off, the lever portion 81 is released from being pressed by the switch protrusion 37, so that the lever portion 81 returns to its original position due to the action of the spring portion 82, and at the same time the pawl 83 separates from the ratchet wheel 79.
At this time, since the pawl 96' of the operating element 86a is elastically engaged with the ratchet wheel 79, there is no reverse rotation and no excessive rotation. Similarly, when the switch handle 10 is turned on again from OFF, the display plate 67 further rotates by a predetermined angle, and the display plate 67 continues to rotate according to the number of times the electric shaver is used. The number of uses is indicated by the number of arc-shaped graduations from one end. Therefore, each time the user uses the electric shaver, he or she will be able to tell how many times the electric shaver has been used since charging the battery. Furthermore, generally, once the display plate 67 has finished rotating by the number of teeth of the gear 71 set according to the battery capacity, if the switch handle 10 is turned on or off, the feed wheel 69 only rotates, and the display plate 67 will no longer rotate. Further, further rotation of the display plate 67 is performed by the display plate 67.
7 stopper protrusion 75 and operation element 86a protrusion 98
Furthermore, the circular arc groove 76 of the display board 67
This is restricted by the engagement of the protrusion 77 of the operator 86a. Therefore, when the display board 67 is to be returned to its original position, it is pressed down in the direction of the return knob 91 shown on the outer surface of the base 58 or in the direction of the arrow N in FIG. This movement of the return knob 91 causes the operator 86a to release the spring 8.
7 in the same direction against the spring action. Due to this movement, the claw 96' of the operator 86a separates from the ratchet wheel 79 of the feed wheel 69, and the feed wheel 69 becomes free, and the protrusion 98 hits the stopper protrusion 75, and the protrusion 98 pushes the stopper protrusion 75. At the initial stage of return, the display plate 67 is rotated in the reverse direction as indicated by arrow M. Further, as the operator 89 continues to move, the side surface of the return arm 97 comes into contact with the cam surface 74 of the cam portion 73, and by pushing the cam surface 74 with the return arm 97, the display plate 67 is moved as shown in FIG. Continue reversing and return to the original position, returning to zero. During this time, the gear 71 of the display board 67 meshes with the gear 78 of the feed wheel 69. On the other hand, when the return knob 91 is released, both the operator 86 and the button 92 return to their original positions due to the action of the spring 87, the operator 86a is supported by the protrusion 95, and the pawl 96' is elastically engaged with the ratchet wheel 79 and clicked. Hold the car 79. In this way, when the battery is in a so-called dead state, by charging the battery and returning the display board to zero, the amount of power consumed by the user when using the razor once is determined until the battery becomes dead. You can know the maximum number of times you can use the product, and you can individually decide how many times you can use it until the battery life reaches that point, and you can always get enough power until that number of times is reached, so the battery will run out in the middle of a shave. can be avoided.

In addition, since the auxiliary return means 98 also serves as a stopper to prevent the display board 67 from being moved too far,
Cam 7 of display board 67 due to excessive rotation of display board 67
It is possible to prevent malfunctions between the cam 73 and the operator 86a (malfunctions due to a large pressure angle, malfunctions due to the cam and the operator not touching the specified positions), and to always keep the cam 73 and the operator 86a in the specified position. It can touch the position. In addition, since a stopper for the operator 86a is formed on the base 58 so that the feed wheel 69 rotates smoothly, the feed wheel 69 provided on the return spring
The locking and fitting state of the locking pawl shown in No. 9 and the feed wheel can be maintained constant, and the spring portion of the return spring acts to protect the locking pawl only when an overload is applied to the locking pawl. , damage to important quality parts of the counter mechanism can be prevented.

Since the locking means and the operator are integrally formed and the operations of the locking means and the operator are linked, the number of parts can be reduced and a compact counter mechanism can be achieved. In addition, by integrating the function to return the display board that displays the number of uses and the latch claw function of the feed wheel necessary to return the display board, the release of the feed wheel and the rotating operation of the display board are continuous. The display board can be easily returned to its original position.

The feed lever has a claw part that sends the feed wheel and a spring part that returns the lever, which are integrally formed, so the balance between the elastic force of the claw part that feeds the feed car and the elastic force that allows it to return automatically is maintained. It can be managed as a component and quality can be stabilized. Note that if the lever shaft portion has a structure that allows it to be fitted and locked onto the shaft of the base, it can be made into a block as a counter block when fitted.
