The operation method of the above-mentioned prior art will now be described. When operating one of the rod-shaped bodies, it has a writing body side axis to be used for the left hand and a right hand side axis for the right side. When the rod-shaped body is projected by rotating the shaft to the right, the shaft on the right hand side is rotated to the left to store it. Also, when operating the other rod-shaped body, first change the front and back of the shaft, hold the rod-side shaft used for the left hand, and rotate the right-hand side shaft to the left to project the rod-shaped body and store it. Will rotate the right-hand side axis to the right. In other words, in the conventional technology, the direction in which the shaft is rotated differs depending on the rod-shaped body used, and there is the inconvenience of making the wrong rotation direction when trying to use it, or if it is a little, it may cause excessive rotation. There was a risk that it would damage the parts inside.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a rod-shaped body feeding container in which a rod-shaped body is retracted by rotating a front shaft and a rear shaft relative to each other. While the cam barrel is provided on the front shaft, the rotor is provided on the rear shaft, and the cam barrel and the rotor are rotatable with respect to each other, but they are fitted so as not to move back and forth. Is formed with a continuous symmetric cam surface, and further, a slider that abuts on the cam surface and moves back and forth is arranged in the cam cylinder, and rod-shaped bodies are arranged in front of and behind the slider, respectively. The gist is that these rod-shaped bodies are retracted from the front shaft and the rear shaft by the forward and backward movement of the slider.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION An example of the present invention will be described with reference to FIGS. In this embodiment, the rod-shaped body is the black ball-point pen and the input pen, but as described above, the rod-shaped body may be a writing tool such as a pencil lead, a colored pencil, a felt-tip pen, or a makeup tool such as lipstick or eyeliner. May be Reference numeral 1 is a front shaft, and a core 2 is fixed inside. A cam barrel 3 is fixed to the core 2, and a rear portion of the cam barrel 3 reaches the inside of the rear shaft 4. On the other hand, a rotor 6 is fixed inside the rear shaft 4, and an engaging projection 6 a is formed on the side surface of the rotor 6. The engaging projection 6a of the rotor 6 is fitted in the inner circumferential groove 3a formed on the inner surface of the cam barrel 3.
That is, the engagement between the engagement protrusion 6a of the rotor 6 and the inner circumferential groove 3a of the cam barrel 3 causes the front shaft 1 and the rear shaft 4 to be
Although it is relatively rotatable, it is mounted so that it cannot move back and forth. Of course, this fitting also prevents the front shaft 1 and the rear shaft 4 from being separated (disassembled).

Reference numeral 5 denotes a slider that slides in the cam barrel 3. A black ball-point pen is fitted and fixed at the front end, and an input pen for a small portable terminal is fitted and fixed at the rear end. Also, 5a
Is a cam surface contacting protrusion of the slider 5 and is in contact with the cam surface 7 of the rotor 6. The cam surface contact protrusion 5a is
It also fits in the long hole 3b formed in the cam barrel 3 to prevent the slider 5 from rotating with respect to the cam barrel 3. Here, the rotor 6 will be described in detail. The cam surface 7 of the rotor 6 is formed symmetrically, for example, in a mountain shape, and a concave portion 7a is formed on the top thereof. It is a concave portion with which the cam surface contacting protrusion 5a of the slider 5 is engaged. Further, in this embodiment, the core 2 and the slider 5 are
A front spring 8 is mounted between the tips of the sliders 5 to constantly urge the slider 5 rearward. Although the front spring 8 is a metal coil spring in the illustrated example, it may be a leaf spring or a non-metal elastic body. Reference numeral 9 denotes a cap, which is fitted to the rear shaft 4 and can rotate integrally.

Next, the operation will be described. 1 and 3 show a state where the black ballpoint pen A is protruding. In this state, the shaft composed of the front shaft 1 and the rear shaft 4 is rotated, that is, the rear shaft 4 is rotated downward. Then, when the cap 9 is rotated clockwise, the cam surface contacting protrusion 5a of the slider 5 is rotated.
Is pushed down to the rear end side from the tip of the cam surface 7 by the elastic force of the front spring 8, the black ball-point pen is retracted into the front shaft 1 and the input pen B is protruded through the rear shaft 4 as shown in FIG. In this case, the slider 5 to which the input pen is fixed is biased only by the front spring 8, and when the pressing force exceeds the load of the front spring when operating the panel or button, the input pen B is pressed. It is designed to prevent excessive load from being absorbed. Here, when projecting the black ballpoint pen A again, first, the front shaft 1 is made to face downward. Then, when the rear shaft 4 is rotated to the right, the input pen B is retracted and the black ballpoint pen A is projected. At this time, even if the rear shaft 4 is rotated to the left, the input pen B sinks and the black ballpoint pen A projects. This is because the cam surface 7 of the rotor 6 is formed symmetrically.

The example shown in FIG. 7 is a modification of the slider 5 and the rotor 6. An outer surface protrusion 5 is formed on the outer peripheral side of the rear end of the slider 5.
b, on the other hand, an inner surface protrusion 6b is formed on the inner periphery of the rear end of the rotor 6 so as to engage with the outer surface protrusion 5b. This is an effective means for fixing a red ball-point pen or the like at the rear end of the slider 5 instead of the input pen B. That is, when writing, it is inconvenient to be immersed as described above, so that the immersion is prevented. In particular,
In the state where the red ballpoint pen is projected, the outer surface protrusion 5b of the slider 5 is positioned behind the inner surface protrusion 6a of the rotor 6, and the front shaft of the slider 5 by the writing pressure of the red ballpoint pen. It is blocking the movement to the side.

In this example, when the black ballpoint pen is projected, the red ballpoint pen is immersed, and when the red ballpoint pen is projected, the black ballpoint pen is immersed. One of them is always projected. You may set so that it will be immersed.
