Further, the fixed side holding portion may be an engaging recess formed on the inner surface of the bearing portion of the shaft cylinder, and the movable side holding portion may be an engaging protrusion integrally formed on the outer surface of the connecting arm portion of the cap. The engaging protrusion formed integrally with the inner surface of the bearing portion of the shaft tube may be used, and the movable side holding portion may be formed as an engaging concave portion formed on the outer surface of the connecting arm portion of the cap. .

Next, as a preferred embodiment of the present invention, a stamp with a writing instrument incorporating the illustrated ballpoint pen will be described in detail.
1 is a synthetic resin shaft cylinder whose lower end is an entrance / exit 1a of the pole pen tip and whose upper end is a seal holder 1b, and 2 is a synthetic resin shaft pivotally attached to the other end of the shaft cylinder 1. A cap 3 is a stamp 3 using a porous stamping material having countless continuous pores fitted in the stamp storing portion 1b of the shaft cylinder 1 described above.

  The above-described shaft tube 1 is integrally formed with a clip portion 4 having a base portion connected to one outer surface on the side of the above-described seal stamp storage portion 1b. The upper portion corresponding to the base portion of the clip portion 4 is formed with a recessed portion from the front surface to the upper surface, and bearing holes 14 are formed in the upper portions of both side plate portions left on both sides thereof. The portion is a bearing portion 11, and further, a fixed side holding portion 12 for holding the cap 2 at a position where the cap 2 does not protrude from the marking surface at the time of using the seal is provided on the both side plate portions of the bearing portion 11. In addition, the fixed side holding part 12 in the illustrated example serves as both a cover rib holding state and a cap opening state holding state of the cap 2 as a small rib-like ridge formed integrally downward from the outside lower side of the bearing hole 14 described above. ing. Further, a locking receiving portion 13 is formed on the outer edge of the cylinder end on the opposite side to the bearing portion 11 of the shaft tube 1.

  On the other hand, the cap 2 that is pivotally attached to the other end of the shaft tube 1 is elastically supported when it is intervened in the bearing portion 11 of the shaft tube 1 on one side of the inverted dish-shaped cap body. A connecting arm portion 21 having a U-shaped cross section is integrally formed as shown in FIG. 5 and an edge portion on the opposite side of the connecting arm portion 21 is formed on the locking receiving portion 13 at the cylinder end of the shaft tube 1. A locking portion 23 that is engaged and held in a covered state is formed, and pins 24 that are coupled to the bearing holes 14 are integrally formed on both outer surfaces of the connecting arm portion 21. The cap 2 is pivotally attached to the other end of the shaft tube 1 by hinge coupling between the pin 24 and the bearing hole 14 described above. Further, a movable side holding portion 22 and a second movable side holding portion 22a are integrally formed outwardly from the pin 24 on both side outer surfaces of the connecting arm portion 21 described above. Then, by pivoting the cap 2 in the covered state in the opening direction, the movable side holding portion 22 gets over the fixed side holding portion 12 and is engaged with the fixed side holding portion 12 until the state shown in FIG. 2 is used, the cap 2 is held at a position where it does not protrude from the marking surface by the engagement of the movable side holding portion 22 and the fixed side holding portion 12, and the cap 2 is closed and the cylinder end of the shaft tube 1 is closed. When the locking portion 23 is engaged with the locking receiving portion 13 of FIG. 3, the second movable side holding portion 22a is engaged with the fixed side holding portion 12 and the double holding state is obtained. It is like that.

  That is, when the cap 2 is closed, the locking portion 23 formed at the edge of the cap 2 gets over the locking receiving portion 13 at the tube end of the shaft tube 1 and is engaged with it. The seal 3 is held in a cover state, so that the seal face of the seal 3 is concealed by the cap 3 and cannot be printed. However, when the cap 3 is pivoted in the opening direction, the engagement portion 23 and the engagement receiving portion 13 The lock due to the engagement is released, and the cap 3 is held in the fully open state.

  In addition, the movable side holding part 22 and the second movable side holding part 22a, which are integrally formed with the fixed side holding part 12 and the bearing part 11 in the above description, have the fixed side holding part 12 as small ridges of a vertically long rib shape, The movable side holding portion 22 and the second movable side holding portion 22a are integrally formed so as to project outward from the pin 24 to the connecting arm portion 21 of the cap 2 within a range in which the movable rib holding portion 22a can be engaged with and disengaged from the above-described vertically long rib-like small ridges. For example, as shown in FIG. 5, the fixed side holding portion 12 is integrally formed with the bearing portion 11 of the shaft cylinder 1. The movable side holding portion 22 is formed as an engaging recess formed on the connecting arm portion 21 of the cap 2, or the fixed side holding portion 12 is formed on the bearing portion 11 of the shaft tube 1 as shown in FIG. And the movable side holding part 22 Such as the engaging projection are integrally formed on the connecting arm portion 21 of the cap 2, it is generally possible to arbitrarily design a range which is used as a means for engaging the movable member to the stationary member.

What is configured in this manner is that the cap 3 that is hinged to the bearing portion 11 on one side outer surface of the end portion of the synthetic resin shaft tube 1 with the connecting arm portion 21 is normally formed at the edge thereof. The locking portion 23 is engaged with a locking receiving portion 13 formed at the tube end of the shaft tube 1 to maintain the cover state. The seal 3 fitted in the tube end opening of the shaft tube 1 is exposed by releasing the lock of the lock portion 23 with respect to the lock receiving portion 13 formed at the tube end 1 and pivoting in the direction in which the cap 2 is opened. This is the same as this type of stamp, which can prevent the drying and damage of the stamped surface or the contamination of other objects due to the stamped surface by closing the cap 2 and returning to the old state when not in use. In the present invention, the fixed side holding portion 12 integrally formed with the bearing portion 11 of the shaft cylinder 1 is provided. On the other hand, a movable side holding portion 22 that is engaged with the fixed side holding portion 12 when the cap 2 is fully opened is integrally formed on the outer surface of the connecting arm portion 21 of the cap 2 pivotally attached to the bearing portion 11. Therefore, simply by fully opening the cap 2, the cap 2 is automatically engaged with the above-mentioned fixed side holding portion 12, and the movable side holding portion 22 is automatically engaged . and seal cap during use is properly held so that Oite seal face and the horizontal in a position not protruding from the seal face as.

  Further, a second movable side holding portion 22a that engages with the fixed side holding portion 12 when the cap 2 is closed is formed integrally with the outer surface of the connecting arm portion 21 of the cap 2 when the cap 2 is closed. In some cases, if the cap 2 is closed after use, the locking portion 23 formed on the edge of the cap 2 is not only engaged with the locking receiving portion 13 at the tube end of the shaft tube 1 but also on the fixed side. Since the second movable side holding portion 12a is automatically engaged with the holding portion 12, the cap 2 is in a double holding state, so that the covering state is more accurate. For this reason, there is no possibility that the stamp face of the seal 3 will be dried or that the stamp face may touch other objects and stain the surroundings.

  Moreover, the cap 2 is held in the open state as described above only by engagement / disengagement between the fixed side holding portion 12 integrally formed with the bearing portion 11 and the movable side holding portion 12 integrally formed with the cap 2. Because it does not use springs and so on, the bearing can be made small and the appearance can be improved, the structure is simple and the number of parts can be reduced, and it is easy to manufacture and can be provided at low cost. A seal can be provided.
