[Detailed description of the invention] (Industrial application field) This invention is a double type in which multiple writing elements are housed in one shaft case (shaft tube), and at least one of them is a knock-type sharp pencil element. It is related to writing instruments.

(Prior art) A knock-type sharp pencil element and a ballpoint pen element are housed in one shaft case, and a slider is connected to the rear end of the sharp pencil element and the ballpoint pen element, and the slider is slid in the axial direction within the cylinder. Wear it freely. It can be rotated by a certain angle around these cylinders, and furthermore, it engages with the sliders of both writing elements to alternately move the writing elements forward and backward in the axial direction as they rotate, thereby alternately protruding the writing position. Writing implements are known that include a cylindrical cam with a cam sliding surface that allows the writing instrument to move.

そして、円筒カムの回動により、筆記要素を筆
記位置と収納位置に進退せしめ、シヤープペンシ
ル要素にノツク作動を与える方法は大別して2つ
に分けられる。
There are two methods for moving the writing element back and forth between the writing position and the storage position by rotating the cylindrical cam, and applying a knocking action to the sharp pencil element.

うものである(例えば、実開昭58−136379号公
報)。
One is that when the slider of the sharp pencil element slides on the cam slide surface and engages with the tip of the cam slide surface, the cylindrical cam itself is moved in the axial direction to provide a knocking action and to feed out the lead. (For example, Japanese Utility Model Application Publication No. 136379/1983).

29173号、実開昭58−123088号公報)。
The other method is to provide the knocking action not by moving the cylindrical cam itself, but by using another knocking member. That is, when the slider of the sharp pencil element engages with the tip of the cam slide surface and is in the writing position, the other knob member that engages with the slider moves in the axial direction to perform centering. For example, Jikko 56-
No. 29173, Utility Model Publication No. 123088/1988).

(考案が解決しようとする問題点) しかしながら、従来公知の構造には次のような
問題があつた。
(Problems to be solved by the invention) However, the conventionally known structures have the following problems.

即ち、円筒カム自体を軸方向に往復推移させて

突起がカム面から外れて円筒カムの内側に侵入し
ノツク不能となる恐れがある。
That is, when the cylindrical cam itself is reciprocated in the axial direction to perform the knocking operation, a strong pressing force is required and the knocking operation becomes heavy. In addition, due to restrictions on the outside diameter, the cylindrical cam can only be made thin, and the tip of the cam surface is at an acute angle. may come off the cam surface and enter the inside of the cylindrical cam, making it impossible to click.

態を確実に保持するのが一層困難になる。
On the other hand, in a structure in which only the movement of the writing element to the writing position is performed by the rotation of a cylindrical cam, and the knock operation is performed by another knob member, the knob is inserted into the groove drilled on the outer surface of the cam. The wall thickness of parts is becoming thinner, and parts are required to be hard and have high dimensional accuracy. In addition, since the knocking member performs the knocking operation by pressing the sliding protrusion of the slider with which the cylindrical cam surface engages, the pressing force is applied to the outside away from the center of the shaft. This also makes it more difficult to reliably maintain the engaged state between the knob member and the slider.

さらに、キヤツプ自体ではなく頭部に設けたノ
ツクキヤツプを押圧する場合には部品点数が多く

Furthermore, in the case where the knock cap provided on the head is pressed instead of the cap itself, the number of parts increases, resulting in an increase in cost.

This idea was made in view of the current situation, and allows the alternating movement of the writing element between the writing position and the storage position and the feeding out of the lead of the sharp pencil element to be carried out smoothly and reliably, while simplifying the overall configuration. By doing so, we aim to reduce parts costs, assembly costs, etc., and provide an inexpensive double-action writing instrument.

(問題点を解決するための手段) そこで、この考案は次のような構成とした。(Means for solving problems) Therefore, this idea was structured as follows.

That is, a plurality of writing elements, at least one of which is a lock-type sharp pencil element, are inserted into a guide groove of a cylinder connected to a shaft case, a slider is connected to the rear end of the writing element, and a slider is connected to the rear end of the writing element. A compound writing instrument comprising a cylindrical cam that is rotatably mounted on the outside of a cylinder and that alternately advances and retreats each writing element into a writing position by sliding with a cam surface that engages with a slider of the writing element, A through hole is bored in the side surface of the cylindrical cam, and the cap is fixed to the cap by arranging the clip part of the knob member, which is formed by integrally forming a clip part and a notch part, on the outside and the notch part inside. Insert the tip of the notch into the through hole on the side of the cylindrical cam and bring it into contact with the top end of the slider from the inside of the cylindrical cam.The slider is pressed by the knob member that moves in the axial direction together with the cap, and the slider is pressed in the axial direction of the cap. The structure is such that the reciprocating movement to and fro is transmitted to the sharp pencil element as a knocking operation to perform centering.

The slider 30 is positioned by sliding on the cam surface 52 and engaging with the tip 54. At this time, the slider 30a is located on the back side of the cylinder 4 and is in contact with the upper surface of the guide groove 45a. If the cap 7 is moved in the axial direction in this state, the knob member 6 will move at the same time, and the pressing part 64 will move against the slider 30.
Press. By reciprocating the cap 7 in this manner, a knocking action is applied to the pencil element 20 and the lead is fed out.

When the cap 7 is rotated, the cylindrical cam 5 is also rotated together, and the pencil element 20 and the ballpoint pen element 21 are alternately moved to the writing position by the sliders 30 and 30a that slide on the cam surfaces 52 and 53, respectively. Advance and retreat. When the ballpoint pen element 21 is in the writing position, the sliding protrusion 31a of the slider 30a is locked to the stepped portion 44 of the cylinder 4, and no knocking operation is performed.
