Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a writing instrument with a seal. 2. Description of the Related Art Conventionally, a writing implement has been constructed in which a tip end of a writing body can be made to protrude and retract at a tip end of a shaft by a knocking operation or a rotation operation, and a seal is attached to a rear end of the shaft of the writing implement. There is a writing implement with a seal having a structure in which a detachable cap is fitted to the seal. [0003] Such a conventional writing implement with a seal has a dissatisfaction that the cap of the seal provided at the rear end portion of the shaft is unsightly, and the appearance is poor, and the fitting degree between the cap and the seal is strong. When the cap is removed, there is a problem that the seal comes off from the shaft when the cap is removed, and further, since the cap is small, the vermilion on the stamp face tends to be attached to the hand and easily lost. [0004] The present invention solves the above-mentioned problems, that is, the appearance of the seal is not obstructive, the appearance is good, and the cap is removed to use the seal. When you do, there is no risk that the seal will come off, the vermilion on the seal will stick to your hands, your hands will be dirty, and the cap will be lost,
It is still another object of the present invention to provide a writing implement with a seal which is not so complicated in the writing mechanism feeding mechanism and the mounting structure of the seal, has a small number of parts, and is advantageous in cost. [0005] In order to achieve the above object, a writing instrument with a seal of the present invention comprises a cylindrical cam 3 attached to a slider 2 housed inside a front shaft 1, and a cylindrical cam 3 attached to the slider 2. Writing body 4 via the slider 2 displaced by the rotation of the cam 3
Is moved in the axial direction so that the tip pen tip 5 can be freely protruded and retracted at the tip end port 6. The seal holder 7 is assembled integrally with the rear part of the cylindrical cam 3 in a rotating manner. The seal 8 is mounted, and the fitting cylinder 9 is fixed to the outer peripheral portion of the seal holder 7, and the fountain pen type cap 10 that accommodates the seal 8 therein in a non-contact state is rotated integrally with the fitting cylinder 9. It is configured to be detachably fitted. In the writing implement with a seal of the present invention, the seal 8 is housed inside the cap 10 and does not appear on the exterior, so that it is not obstructive. Moreover, the appearance of the cap 10 is good because the cap 10 is a fountain pen type. Further, since the cap 10 is in a non-contact state with the seal 8, there is no possibility that the seal 8 comes off when the cap 10 is removed. Further, since the cap 10 is a fountain pen type and large as described above, there is no possibility that the hand touches the stamp surface when the cap 10 is removed or the removed cap 10 is lost. An embodiment shown in the drawings will be described in detail below. First, reference numeral 1 denotes a front shaft, and this front shaft 1 has a base 11 at its front end.
And a lid ring 12 is screwed to the rear end. A writing body 4 such as a ballpoint pen refill, a slider 2, a cylindrical cam 3, and a spring 13 are housed inside the front shaft 1. The writing body 4 has a rear end fitted into the inner hole of the slider 2. The slider 2 is assembled with the cylindrical cam 3 and urged rearward by a spring 13. The cylindrical cam 3 is prevented from falling off by a lid ring 12. As shown in FIG. 3, the slider 2 is provided with a curved step 14 which is displaced in the axial direction on the rear half side surface, and is provided with an axial rib 15 on the front half side surface. By fitting into an axial groove 16 (see FIG. 1) provided on the inner surface of the shaft 1, the shaft 1 is slidable in the axial direction with respect to the front shaft 1.
It cannot rotate in the circumferential direction. As shown in FIG. 3, the cylindrical cam 3 forms a cam portion 17 by making the front end edge of the peripheral wall of the front half cylindrical portion uneven.
At the rear end, a connection cylinder 20 having a rectangular cross section and having a slit 18 and an engagement flange 19 is protruded. The cylindrical cam 3 can displace the slider 2 back and forth in the axial direction by rotating the cylindrical cam 3 by bringing the cam portion 17 into contact with the step 14 of the slider 2. Therefore, the writing body 4 also moves forward and backward through the slider 2 by the rotation of the cylindrical cam 3, and the tip 5 of the writing tip can be freely retracted at the shaft tip opening 6 at the front end of the base 11. In addition, the connecting cylinder 20 at the rear end of the cylindrical cam 3
Protrudes rearward through the lid ring 12. Reference numeral 7 denotes a seal holder. The seal holder 7 has a double cylinder portion in the first half, and has an inner cylinder portion 21 provided with an inner hole 22 having a rectangular cross section. The cylindrical cam 3 is rotatably and integrally joined to the cylindrical cam 3 by inserting and locking the connecting cylindrical portion 20 provided at the rear end of the cylindrical cam 3. Further, the outer cylindrical portion 23 in the first half of the seal holder 7 is provided.
A fitting cylinder 9 is fitted and fixed to the outer periphery of the. The fitting tube 9 has a ridge 24 on the side surface as shown in FIG. A seal 8 is attached to the latter half of the seal holder 7. The seal 8 is referred to as a penetrating seal, and includes a stamp material 25, a vermilion impregnated body 26, a cover 27, a base 28, and the like.
8 is fitted and attached to the rear half cylinder portion of the seal holder 7. Next, reference numeral 10 denotes a fountain pen type cap, and this cap 10 has a clip 29 at the top end.
0 and fix it inside.
1 is attached. The inner cap 31 is fixed by a stopper 33 fitted to a projection 32 of the crown 30 penetrating into the inside of the cap. A decorative ring 34 is attached to the opening edge of the front end of the cap 10. This cap 10
Is put on the outer periphery of the seal and the seal holder 7, and is fixed by bringing the inner surface into contact with the fitting cylinder 9 fixed to the seal holder 7. In the fitted state of the cap 10, a slight gap is formed between the inner surface of the cap and the seal 8 by the protrusion 24 of the fitting cylinder 9, and the cap 10 maintains the non-contact state with the seal 8. The cap 10 is detachable from the fitting tube 9, and the cap 10 is
And fixed with such a force that the rotation in the circumferential direction is integrated.
Thus, when the cap 10 is rotated, the fitting cylinder 9 and the seal holder 7 are also integrally rotated, and further, the seal holder 7 is further rotated.
The cylindrical cam 3 also rotates integrally. Accordingly, the slider 2 can be moved back and forth by the turning operation of the cap 10 as described above, and the tip portion 5 of the writing body 4 can freely come and go at the shaft tip opening 6. When the seal 8 is used, of course, the cap 10 is used.
Remove. When the cap 10 is removed, since the cap 10 and the seal 8 are in a non-contact state as described above, there is no possibility that the seal 8 is pulled out of the seal holder 7 by being dragged by the cap 10.
Since the cap 10 is a fountain pen type and large, the cap 1
There is no danger of the hand touching the stamp surface when removing 0, and there is no danger of the removed cap 10 being lost. [0013] The present invention is as described above.
Is completely obstructed because it is completely contained inside the cap 10 and does not appear on the exterior, and since the cap 10 is a fountain pen type, its appearance is extremely good. Next, cap 10
Since is not in contact with the seal 8, there is no possibility that the seal 8 will come off when the cap 10 is removed. In addition, since the cap 10 is a fountain pen type and large as described above, there is no danger of the hand touching the stamp surface when the cap 10 is removed, and the cap 10 is easily noticeable even when it is removed. In addition, the slider 2 and the cylindrical cam 3 are used to extend and retract the tip 5 of the writing body 4, and the seal holder 7 is joined to the cylindrical cam 3, so that the writing body feeding mechanism and the seal are provided. Since the mounting structure is not complicated and the number of parts is small, the manufacturing cost can be reduced.
