The other side surface 30b is a positioning protrusion 39 for the cylindrical body 36.
When the protrusion 31 comes into contact with the other side surface 39b, the protrusion 31 is forcibly fitted into the third recess 38c. As the cylindrical cam 26 rotates, the writing unit 8 in the storage position moves forward to the writing position as shown in FIG. 2 with the driven protrusion 15 of the sliding piece 12 being guided by the cam surface 27. On the other hand, writing unit 7 has its sliding piece 1.
The second driven protrusion 15 is guided by the cam surface 27 and further retreats. From this state, the knob cover 44 is pressed to move the cylindrical cam 26, sliding piece 12, and writing unit 8 forward against the elasticity of the compression spring 35. As the writing unit 8 moves forward, when the rear step 45 of the cap 11 comes into contact with the inner edge of the opening 2 of the outer case, the lead case pipe 10 moves forward as described above, which causes the lead feeding mechanism inside the main body 9 to move forward. do. On the contrary, by releasing the pressing force of the knock cover 44, the writing unit 8, the sliding piece 12, the cylindrical cam 26, and the knock cover 44 return to their original positions due to the elasticity of the compression spring 35, and the lead feeding mechanism inside the main body 9 also retreats. Therefore, by knocking the knock cover 44, the lead l can be successively projected from the cap 11 to perform writing or other tasks.

By selectively engaging the first and third recesses 38a and 38c of the cylindrical cam 26, the writing unit 7 or 8 can be selectively projected to the writing position. Both writing units 7 and 8 can be stored by engaging with the second recess 38b, and at this time, the protrusion 31 and the first to third recesses 38a to 38c are switched with moderation and positioned. The protruding position and storage position of the writing unit can be recognized by hearing and tactile sensation.

よい。 Incidentally, in the above embodiment, the cylinder body 3 for rotation angle indexing is
Since the cylinder body 36 is formed thick, a notch groove 41 for inserting the core is formed in the cylinder body 36.
If the notch groove 41 is formed thinly, the notch groove 41 does not need to be formed. Further, in the embodiment described above, both writing units 7 are configured as ballpoint pens, and writing unit 8 is configured as a click-type mechanical pencil. It is also possible to use different leads, such as, etc., and in short, it is sufficient to use a knot-type sharp pencil for at least one of them. In the above embodiment, the cylindrical cam 26 is provided with a positioning protrusion 31, and the cylindrical body 36 is provided with recesses 38a, 38b, and 38c that selectively engage with the protrusion 31. 38a, 3
8b and 38c can be omitted, so if you use a knock-type pencil pencil for both as described above,
Only the notch 25 for inserting the core of the guide 16 (the cylinder 36
(if the cylinder is thin), or the notch 25 and the notch groove 41 for inserting the core of the cylinder 36 (if the cylinder 36 is thick)
may be provided symmetrically at two locations. Further, the cylindrical cam 26 may be provided integrally with the rear shaft 5 to support the rear shaft 5 slidably with respect to the front shaft 3.
may also be provided so as to be rotatable relative to the rear shaft 5.

行うことができる等の利点がある。 As is clear from the above explanation, according to the present invention, two writing units each using a lock-type sharp pencil on at least one side are supported inside the outer case so as to be movable back and forth between the writing position and the storage position. Sliding pieces are attached to the rear ends of the writing units approximately 180 degrees apart, and a guide is fixed inside the outer case to guide the sliding pieces of each writing unit so that they can only slide, and the sliding pieces move forward inside the outer case. A retreating cam is rotatably provided with respect to the guide, and a spring attached to each writing unit urges each sliding piece and writing unit toward the cam. Therefore, the two writing units can be selectively protruded to the writing position along the cam and used for different purposes, making it easier to perform office work and carry the device. In addition, a hole for inserting a lead is formed in the sliding piece of a writing unit using a knock-type mechanical pencil, and this hole for inserting a lead is communicated with a notch for inserting a lead formed in the guide. Since it is open toward the knock cover side, there are advantages such as the ability to easily and quickly carry out core replenishment work.
