Claims (1)

[Claims for Utility Model Registration] 1. (a) A fixing part 1 which is substantially cylindrical and is fixed to a writing instrument A inserted inside thereof by a leaf spring 3 or the like and is detachable. (b) A counting mechanism B1, which is a conventional technique, is attached to the fixed part 1. (c) A movable part 2 which is approximately cylindrical, contacts the outer periphery of the fixed part 1, is connected to the fixed part 1 by a spring 4, etc., and is movable in the longitudinal direction of the writing instrument by the force of the writing instrument during writing, and is capable of returning. (d) A protrusion 6 fixed to the movable part 2 and engaged with the cam 5 of the counting mechanism B1. Counter configured as above. 2. The counter according to claim 1, wherein instead of the cam 5 and the protrusion 6, a conventional mechanical mechanism is installed to link the movement of the movable part 2 with the operation of the counting mechanism B1. 3 (a) In place of the counting mechanism B1, an electronic counting mechanism B2 consisting of a counting circuit, a display unit, a battery, etc., which adds a count of 1 each time electricity is applied, is attached to the fixed part 1, and (b) the cam 5, etc. 2. The counter according to claim 1, wherein, in place of the protrusion 6, an electric switch 7 is installed which is electrically connected to the electronic counting mechanism B2 and moves toward and away from the moving part 2 in conjunction with the movement of the movable part 2. 4 Instead of the movable part 2 and electric switch 7,
4. The counter according to claim 3, wherein the fixed part 1 is equipped with a push-button electric switch 8 which is electrically connected to the electronic counting mechanism B2 and which opens and closes in response to a force applied to a finger during writing. 5 (a) A small desk electronic calculator with a counting function, which is a conventional small desk electronic calculator equipped with a counting circuit that increments the count by 1 each time electricity is applied, and a plug socket electrically connected to this circuit. B3 is one element of the combination; (b) instead of the electronic counting mechanism B2, an electric cord 9 is attached to the fixed part 1, and one end thereof is used as a plug to be inserted into the small desk electronic calculator B3 with a counting function; The counter (count detector 10) according to claim 3 or 4, the other end of which is electrically connected to the electric switches 7, 8, is used as the other element of the combination. The counting detector according to (b) above, which is used in combination with a small desktop electronic calculator with a counting function as described above. 6. The counter or counting detector according to claim 1, 2, 3, 4, or 5, which is formed by integrating the fixed part 1 with a writing instrument A or the like, and is also used as a writing instrument.
