Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a multi-color writing instrument with a knob, which has a built-in plurality of writing fonts and allows the cursive fonts to be replaced and protruded one after another by operating the knob.

(Prior art) Conventionally, for example, in the case of a two-color knot-type writing instrument, in order to make the writing part protrude and retract from the barrel, the tip of the tip of the tip is generally tapered, so a larger stroke is required than when making a single-color one protrude and retract. A notch is required, and in the case of a single color, the stroke required is about 8 mm.
mm, and there was a defect that the protruding length of the knob became large, which spoiled the appearance, especially when carried.

(Problem to be solved by the invention) The purpose of the invention is to provide a grip-type multicolor writing instrument that is convenient to carry by shortening the protruding length of the grip stick to the same length as when writing. It is something to do.

(Means for Solving the Problems) In order to achieve the above object, the knock-type multicolor writing instrument of the present invention is designed such that one of the plurality of writing instruments stored in the barrel 7 can be selected by the knob operation of the knob rod 1. In a book-feeding type multicolor writing implement, a cam rotor 2 moves forward under pressure from a knob rod 1 and rotates in the circumferential direction at a required angle, and as the cam rotor 2 rotates, its pressing portion sequentially comes into contact with the cam rotor 2. Equipped with a knock mechanism that can attach more cursive pressers 6 that transmit knock pressure than the number of cursives housed in the barrel 7, the number of cursive pressers 6 greater than or equal to the number of cursives stored in the knob mechanism is provided. 6, when the knock rod 1 is knocked, the pressing part of the cam rotor 2 comes into contact with the extra writing presser 6 that does not press the writing, or the pressing part of the cam rotor 2 This configuration is characterized in that the cursive presser 6 is located at a location where the cursive presser 6 does not exist.

(Function) By knocking the knock rod 1, the pressing part of the cam rotor 2 comes into contact with the extra cursive pressing element 6 that does not press the cursive, or the pressing part of the cam rotor 2 contacts the cursive pressing element 6. 6 is located where it does not exist, the cursive does not protrude, so it can be carried in this state, and in this state, the dowel stick is knocked, so the dot stick 1 can be carried. The length of the protrusion from the barrel is shortened to the same length as when writing.

(Embodiment) In the embodiment shown in FIG. 1, a so-called ball-point refill, which has a structure in which a ball-point pen tip 4 is attached to the tip of a pipe body 5, is used as a cursive writing body. The cam rotor 2 is thus biased and pressed by the above-mentioned knock rod 1 to move forward and rotate by the required angle, and as the cam rotor 2 rotates by 120 degrees, it sequentially comes into contact with the pressing part of the cam rotor 2. A knocking mechanism is constituted by three writing pressers 6 that are in contact with each other and to which knocking pressure is transmitted from the cam rotor 2. Two cursive pressers 6 are connected to the rear ends of the pipe bodies 5 of the three ballpoint pen refills to enable the three ballpoint pen refills to appear and retract. With only the ballpoint pen refill attached, an extra cursive presser 6 that is free, that is, not connected to the ballpoint pen refill, is provided, and this extra cursive presser 6 is kept in the state of being clicked. That is, as shown in FIG. 1, the ballpoint pen is intended to be carried in a state in which the refill does not protrude and the protrusion length of the knock rod 1 from the barrel is shortened. Here, three cursive pressers 6, which are more than two ballpoint pen refills, are attached to the knob mechanism, but the cursive pressers 6 are removed from the integral locking mechanism, that is, in advance. Only two cursive pressers 6, the same number as the number of ballpoint pen refills, may be attached. Figure 2 shows the state in which a conventional multicolor writing instrument is carried, that is, when the ballpoint pen refill is recessed into the barrel, the protruding length of the knob bar 1 from the rear end of the barrel becomes longer. Not only is it inconvenient to carry, but it also doesn't look good on the outside.

(Effect of the invention) The present invention is as described above, and the cam rotor 2, which moves forward under pressure from the knock rod 1 and rotates in the circumferential direction at a required angle, sequentially hits its pressing portion as it rotates. Equipped with a knock mechanism that can attach more cursive pressers 6 than the number of cursives housed in the shaft tube 7, which are in contact with each other to transmit knob pressure, so that the number of cursives larger than or equal to the number of cursives stored in the knob mechanism is installed. By attaching the presser 6, when the knock bar 1 is knocked, the pressing part of the cam rotor 2 will come into contact with the extra cursive presser 6 that does not press the cursive, or the cursive presser 6 of the cam rotor 2 Since the pressing part is located at a location where the cursive presser 6 does not exist, the cursive does not protrude even when the knock rod is struck, that is, the cursive does not protrude and the cursive does not protrude from the barrel. Since it can be carried with the protruding length of the knob bar shortened to the same length as when writing, the convenience of carrying is improved and the appearance when carried is also improved.

Claims (1)

[Scope of utility model registration request] In a knock-type multi-colored writing instrument in which one of a plurality of writing fonts stored in a barrel 7 is drawn out by the knob operation of the knob rod 1, it is pushed forward by the knob rod 1 and moves in a circle at a required angle. A cam rotor 2 that rotates in the circumferential direction sequentially brings its pressing portion into contact with the rotation of the cam rotor 2 and transmits the knob pressure.A number of writing pressers 6 can be attached to the shaft cylinder 7 in a number greater than the number of writing materials stored therein. By equipping the knock mechanism with a number of cursive pressers 6 greater than or equal to the number of cursives, the pressing part of the cam rotor 2 presses the cursives when the knock rod 1 is knocked. A notch-type multicolor device characterized in that the pressing part of the cam rotor 2 is brought into contact with an unnecessary cursive presser 6 or is located at a location where the cursive presser 6 does not exist. Writing implements.
