 Hereinafter, embodiments will be described with reference to the drawings. First, the shaft 1 is composed of a front shaft 2 and a rear shaft 3, and a seal 4 is attached to the rear end of the shaft 3 thereafter. The stamp 4 is composed of a printing body 5 made of a porous printing material such as sponge rubber having innumerable continuous pores that can be impregnated with ink, an ink storage body that stores ink to be supplied to the printing body 5 (not shown). ) Is fixed to a base 7 by a cover 6, and the base 7 is fitted to the outer peripheral portion of an inner cylindrical portion 8 formed at the rear end of the rear shaft 3. A cap 9 having an open top end (rear end) is fitted on the outer peripheral portion of the rear shaft 3 so as to be slidable in the axial direction and integrally rotatable in the circumferential direction. A clip mounting base 10 is provided on the outer surface of the rear end of the cap 9, and a base end of a lid 12 capable of opening and closing a top end opening 11 of the cap 9 is pivotally attached to the rear end thereof. A torsion coil spring 13 is attached to the shaft mounting portion so as to urge the lid body 12 in the closing direction.

The lid 12 is inclined so that the base end side thereof is located forward of the tip end side in the closed state. Therefore, when the cap 9 is slid forward with respect to the shaft 1, the seal 4 is relatively retracted with respect to the cap 9, and a part of the cover 6 near the shaft attachment portion of the cover 12 is removed at the rear end peripheral edge portion. Since the lid 12 is pushed rearward by coming into contact with the inner surface side end portion of the lid body 12 on the base end side, the lid body 12 rotates about the shaft attachment portion and the top end opening 11 of the cap 9 is opened. The seal 4 can be imprinted by projecting rearward from the top end opening 11 of the cap 9. Further, a flange 35 is formed on the front outer periphery of the rear shaft 3, the front end portion thereof is brought into contact therewith, and the return spring 33 is fitted on the outer periphery of the rear shaft 3 so that the rear end is formed on the inner surface of the cap 9. The cap 9 is provided so as to be in contact with the collar portion 34 and always urge the cap 9 rearward with respect to the shaft 1 to close the lid 12.

On the contrary, when the cap 9 is slid backward with respect to the shaft 1, the lid 12 closes the top end opening 11 of the cap 9 by the action of the torsion coil spring 13, and the printed body 5 of the seal 4 is printed. Hide and protect. Of course, the base end of the clip 14 is fixed to the clip mounting base 10, and the base end of the clip 14 is provided with a window hole 15 for opening an inner surface and an outer surface thereof. A substantially central portion of a lever 16 is rotatably attached to a position on the inner surface side of the clip 14 at the front end portion of the clip mount 10. The lever 16 is provided with an engaging projection 17 on the inner surface of the front end and a push button 18 on the outer surface of the rear end so that the engaging projection 17 can be retracted into the cap 9 through a long hole 19 formed in the cap 9. Further, the push button 18 is penetrated from the window hole 15 of the clip 14 to the outer surface side of the clip.

A coil spring 20 is interposed between the inner surface of the push button 18 and the outer surface of the cap 9, and the engagement protrusion 17 is constantly urged inward of the cap 9. On the other hand, engaging grooves 21 and 21 'are provided in the outer surface portion of the rear shaft 3 inside the cap, which are engaged with the engaging protrusions 17 of the levers 16 and can be locked at two positions at different axial positions. .. Of these, the rear engagement groove 21 is positioned so that it exactly corresponds to the engagement protrusion 17 when the cap 9 retracts with respect to the shaft 1 and the lid 12 closes the cap top end opening 11. Further, the front engagement groove 21 'is in a state in which the cap 9 advances with respect to the shaft 1 and the lid 12 opens the cap top end opening 11 as described above and the seal 4 projects rearward of the cap. The position is set so as to correspond to the engaging protrusion 17. That is, a locking device is formed between the cap 9 and the shaft 1, particularly the rear shaft 3, by the lever 16 having the engaging projection 17 and the engaging grooves 21 and 21 'with which the engaging projection 17 engages. It

To release the locked state between the engaging groove 21 ′ and the engaging protrusion 17, the push button 18 of the lever 16 is pushed inward of the clip 14 to lift the engaging protrusion 17 and escape from the engaging groove 21 ′. On the contrary, in order to lock the engagement projection 17 in the engagement groove 21 ′, the cap 9 is slid to the predetermined position with respect to the rear shaft 3 while the push button 18 is being pressed, and the push button 18 is pressed. When released, the engaging projection 17 is automatically fitted into the engaging groove 21 'and locked by the action of the coil spring 20. Further, a rounded portion 36 is appropriately formed at the tip of the engaging projection 17 of the lever (a rounded portion may be formed at the tip of the engaging groove 21), and when the cap 9 slides on the shaft 1. The tip of the engaging projection 17 is lifted by an appropriate resistance force so that the engagement with the engaging groove 21 is released.

Since the above-mentioned return spring 33 is urged between the shaft 1 and the cap 9, the cap 9 is slid forward with respect to the shaft 1 to open the lid 12 to open the seal 4 When exposing, the compression resistance of the return spring 33 is added. A resistance of about 500 to 1000 g is suitable. When the seal 4 is stored, the lock state is released by pressing the push button 18, and the cap 9 is retracted with respect to the shaft 1 by the return force of the return spring 33 and the top end opening of the cap is opened by the lid 12. 11 is closed. It should be noted that the push button 18 is preferably installed at a position where a finger always touches when the writing instrument with a seal stamp is inserted into a breast pocket or the like. In the embodiment of the present invention, it is provided on the upper surface of the rear end of the clip 14. It is also possible to connect the lever 16 so as to interlock with the clip 14 so that the lock is released when the tip of the clip floats.

The front half of the guide cylinder 22 is inserted and fixed in the front shaft 2, and the rear half of the guide cylinder 22 is inserted in the rear shaft 3 to form the rear end boss portion 23. The rear end of the rear shaft is inserted into the center hole of the inward brim portion 24 in the inner cylindrical portion 8 so as not to be pulled out in the axial direction and relatively rotatable in the circumferential direction. The guide cylinder 22 is provided with a plurality of guide grooves 25 in the axial direction, and each guide groove 25 is provided with a sliding piece 28 attached to the rear end of a plurality of ball-point pen refills 26 of different colors via a receiving rod 27. Each of the coil springs 29 is biased rearward and fitted.

On the other hand, on the inner surface portion of the rear shaft 3, a cam slope 30 that is displaced in the axial direction is formed over a required range in the circumferential direction, and the cam slope 30 is brought into contact with each sliding piece 28, By rotating the cap 9 which is integrally rotated with the rear shaft 3, the required sliding piece 28 is moved forward by the cam slope 30 and the tip writing portion 31 of the required ball-point pen refill 26 is projected from the front shaft tip opening 32. It is possible. It should be noted that the writing means provided inside the shaft 1 is not limited to these and may be any one.

[Effect of the device]

 The structure and operation of the seal stamp of the present invention are as described above, the conventional cap attachment / detachment operation is not required, and the usability is improved, and the cap 9 does not need to be detached from the shaft 1 when marking is performed. Since it is only necessary to rotate the lid 12 attached to the cover 9, the risk of loss of the cap 9 and the lid 12 is eliminated, and when the cap 9 is slid, the print surface of the seal 4 is manually touched. Since it is hard to touch, it also has the effect of eliminating the risk of soiling your hands. In addition to the above, the present invention also provides a state in which the seal 4 is projected from the top opening 11 of the cap between the cap 9 and the shaft 1 and the seal is immersed inside the cap so that the top opening of the cap is covered by the lid 12. A lock device is provided to lock the two in the closed state, and when the return spring 33 is further attached between the cap 9 and the shaft 1 to release the lock, the cap 9 is always retracted and the lid 12 is opened. Since it is designed to be closed, the top end opening 11 of the cap is closed by the lid 12 when it is inserted into a chest pocket or the like even if the seal 4 is exposed by improper operation or the lock is incomplete. This prevents accidents that stain your hands or clothes. Further, when the shaft 1 is knocked (slipped) with respect to the cap 9, the seal stamp is projected, and when the push button 18 is pushed, the seal stamp 4 is stored and closed, so that the usability is improved.
