A downward movement restricting projection 28A is formed. The seesaw switch 72, the upper movement restricting protrusion 27, the lower movement restricting protrusion 28A, and the like constitute the lock mechanism of the stamp 1 according to this embodiment.

  The stamp 1 stores a printing body 30 having a marking surface 32 inside the inner cylinder 20. The printing body 30 has a substantially cylindrical shape. For example, as shown in the cross-sectional views of FIGS. 4 and 5, the printing body 30 passes through the opening 24 of the inner cylinder 20 and is supported by the top plate portion of the outer cylinder 10. Thereby, the printing body 30 is configured to move up and down integrally with the outer cylinder 10.

  The opening / closing lid 40 is a member that is rotatably attached to the inner cylinder 20. The follower shaft portion 45 of the opening / closing lid 40 passes through a hole portion where the cam hole portion 12a or 12b formed in the outer cylinder 10 and the cam hole portion 22 formed in the inner cylinder 20 intersect. That is, in the stamp 1 of this embodiment, for example, the cam hole portion 12a or 12b of the outer cylinder 10 having a shape as shown in FIG. 2 and the cam hole portion 22 of the inner cylinder 20 as shown in FIG. A cam mechanism in which the follower shaft portion 45 of the opening / closing lid 40 is restrained is provided in the hole portion. With such a cam mechanism, the opening / closing lid 40 rotates to the opening side as the outer cylinder 10 moves down into the inner cylinder 20, and conversely to the side to close as the outer cylinder 10 moves up from the inner cylinder 20. It is configured to rotate. The marking surface, which is the lower surface of the printing body 30, is closed by the opening / closing lid 40 at the position where the inner cylinder 20 protrudes most from the outer cylinder 10. As a result, the ink pad 60 held by the opening / closing lid 40 abuts against the printing surface 32 and ink is supplied to the printing surface 32.

  The opening / closing lid 40 according to the present embodiment will be further described. As shown in FIG. 10, the opening / closing lid 40 includes a front surface portion 41 in which a rectangular opening 44 is formed, a follower shaft portion 45 formed in an arm portion extending from the upper end of the front surface portion 41, and an ink described later. Each part including notch plate portions 42L and 42R (container holding portions) for detachably holding the pad container 50 is a member formed integrally.

  In this embodiment, the ink pad 60 for supplying ink to the printing surface 32 of the printing body 30 is accommodated in, for example, an ink pad container 50 shown in FIGS. And this ink pad container 50 is hold | maintained so that insertion / extraction is possible in the container holding part formed in the opening-and-closing lid 40. FIG.

  As shown in FIG. 11, the container holding portion of the opening / closing lid 40 is formed to include a pair of left and right cutout plate portions 42L and 42R. The notch plate portions 42L and 42R are separated by a center notch, and the neck portion of the ink pad container 50 is inserted into the notch. At each notch edge of the notch plate portions 42L and 42R, a substantially semicircular first protrusion 42a and a substantially semicircular second protrusion 42b are formed apart from the tip to the inside. Yes. That is, the first groove portion 43a and the second groove portion 43b are formed by being arranged from the leading end to the inside along the notch edges of the notch plate portions 42L and 42R. In addition, as shown in FIG. 11, the container holding portion is narrowed by first projecting portions 42a and 42a in which the insertion ports of the notches between the respective notched plate portions 42L and 42R protrude from both ends to face each other. It is preferable to be formed.

  For example, as shown in FIGS. 12 and 13, the ink pad container 50 includes a bottomed cylindrical pad containing portion 52 having an opening on the lower side, and a substantially quadrangular parallel plate on the upper surface side of the pad containing portion 52. Each member includes a knob portion 53 and a substantially semi-annular top 51 protruding from the front surface side of the pad housing portion 52. The ink pad container 50 further has a first fitting portion 54 a and a second fitting portion 54 b that are substantially semicircular projections formed on both sides of the neck portion between the pad housing portion 52 and the knob portion 53.

  The ink pad 60 (see FIGS. 4 and 5) is accommodated in the pad accommodating portion 52 of the ink pad container 50. In addition, as a material of the ink pad 60, the polyolefin fiber which uses polyethylene (PE) and polypropylene (PP) as a raw material can be used, for example. The ink impregnated in the ink pad 60 can be used as appropriate regardless of whether it is pigment-based, dye-based, oil-based, or water-based. For example, as a fast-drying ink for imprinting on hard-to-absorb paper such as coated paper, plastic film, aluminum, and iron, or non-absorbent material, an oil-based ink in which a colorant or a resin is dissolved and mixed in a quick-drying solvent is used. it can.

  In the present embodiment, the ink pad container 50 is detachably held in a container holding part formed on the opening / closing lid 40 (FIG. 17A). In addition, the container holding portion provided in the opening / closing lid 40 includes a set position (FIG. 17C) where the ink pad 60 can come into contact with the printing surface 32 and a preset position (FIG. 17B) slightly shifted outward from the set position. The ink pad container 50 is configured to be fitted and held.

  That is, when the ink pad container 50 is inserted into the container holding portion of the opening / closing lid 40, first, as shown in FIG. 17B, the first fitting portion 54a of the ink pad container 50 is the first of the notch plate portions 42L and 42R. It fits in one groove part 43a. At this time, the ink pad container 50 is temporarily held at the preset position of the container holding portion of the opening / closing lid 40 with the top 51 entering the opening 44 of the opening / closing lid 40. When the ink pad container 50 is further pushed in, as shown in FIG. 17C, the first fitting portion 54a of the ink pad container 50 is fitted into the second groove portions 43b of the notch plate portions 42L and 42R, and the second fitting is performed. The mating part 54b fits into the first groove part 43a. Thereby, the ink pad container 50 is stably held at the set position of the container holding portion of the opening / closing lid 40.

  According to the stamp 1 of the present embodiment, the ink pad container 50 can be fitted and held in the container holding portion formed on the opening / closing lid 40 in two stages of the set position and the preset position. When the ink pad container 50 is taken out from the set position of the opening / closing lid 40, the ink pad container 50 is once fitted and held in the preset position, so that the ink pad container 50 does not pop out carelessly. Further, there is no possibility that the ink pad container 50 will fall when the opening / closing lid 40 is opened. Further, since the ink pad container 50 can be detachably removed from the opening / closing lid 40, operations such as replacement of the ink pad 60 and replenishment of ink to the ink pad 60 with reduced ink storage amount can be easily performed. it can.

  Moreover, in the stamp 1 of this embodiment, the coil spring accommodated in the outer cylinder 10 in a compressed state imparts a resilient force to the inner cylinder 20, so that the inner cylinder 20 protrudes from the outer cylinder 10 when not in use. It is in a state. In this state, the opening 23 of the inner cylinder 20 is closed by the opening / closing lid 40, and the ink pad 60 accommodated in the ink pad container 50 of the opening / closing lid 40 is placed on the printing body 31 stored in the inner cylinder 20. Opposing and abutting on the marking surface 32. As a result, ink is supplied to the stamp surface 32.

  At the time of stamping by the stamp 1, as shown in FIGS. 7 to 9, the outer cylinder 10 is moved downward by placing the lower end 20 a of the inner cylinder 20 against the paper surface and pressing the outer cylinder 10 toward the paper surface. In conjunction with this, the opening / closing lid 40 opens outward. When a further pressing force is applied to the outer cylinder 10, the marking surface 32 of the descending printing body 31 is exposed from the lower end portion 20 a of the inner cylinder 20, and the imprinting surface 32 is brought into contact with the paper surface, whereby the imprint is transferred to the paper surface.

  When the pressing of the outer cylinder 10 is released after the marking is completed, the inner cylinder 20 returns to the initial protruding position by the elastic force of the compressed coil spring. In conjunction with this, the opening / closing lid 40 closes to the inner cylinder 20 side.

  Next, a lock mechanism provided in the stamp 1 of the present embodiment and adapted to lock the sliding movement of the outer cylinder 10 relative to the inner cylinder 20 will be described. The lock mechanism includes a seesaw switch 72 for performing operations for locking and unlocking the sliding movement of the outer cylinder 10, and a slide switch 71 configured to be able to move the seesaw switch 72 left and right.

  FIG. 18 shows a perspective view of the slide switch 71. In the slide switch 71, an opening 71a into which the seesaw switch 72 is fitted is formed in the center of a rectangular plate-like main body. Bearing portions 71b that receive the rotation shaft portion 72b of the seesaw switch 72 are formed on the left and right rear surfaces of the opening 71a. In addition, a locking portion 71c for locking the outer cylinder 10 so as to be slidable is formed along the upper and lower surfaces of the slide switch 71 main body.

  FIG. 19 shows a perspective view of the seesaw switch 72. The seesaw switch 72 is a member that is substantially L-shaped in appearance. The seesaw switch 72 has a hook portion 72a that protrudes rearward from the lower portion of the main body. On the left and right surfaces of the main body, a rotation shaft portion 72b that is supported by the bearing portion 71b of the slide switch 71 is extended. In addition, a protrusion 72c for hooking a finger is formed on the front upper portion of the main body so that the user can easily perform a pressing operation.

  In the lock operation unit 70, the seesaw switch 72 is fitted in the opening 71 a of the slide switch 71, and is provided on the back surface of the outer cylinder 10, that is, the surface opposite to the opening lid 40. As shown in FIGS. 20A and 20B, the lock operation unit 70 is configured such that the seesaw switch 72 moves left and right by a slide operation to the slide switch 71. The seesaw switch 72 is pivotally supported by the slide switch 71 and is rotatable.

  Here, FIGS. 21 to 23 are longitudinal sectional views showing an embodiment of a locking mechanism adapted to lock the sliding movement of the outer cylinder 10 relative to the inner cylinder 20. As shown in these drawings, the seesaw switch 72 is always urged by the elastic force of the leaf spring portion 15 provided integrally with the outer cylinder 10 so that the hook portion 72a enters the inner cylinder 20 side. ing.

  FIG. 21 shows that the slide switch 71 is operated to the right position (see FIG. 20B) when the stamp surface 32 is stored in the inner cylinder 20 (the inner cylinder 20 is in the protruding state and the opening / closing lid 40 is in the closed state). The state where the downward movement of the cylinder 10 is locked is shown. In this case, as shown in the figure, the hook portion 72a of the seesaw switch 72 is blocked by the downward movement restricting projection portion 28A provided on the inner cylinder 20, whereby the downward movement of the outer cylinder 10 and the seesaw switch 72 are performed. The unlocking operation is restricted at the same time. In this case, the rotation range of the seesaw switch 72 is preferably set to a range in which the hook portion 72a does not exceed the height of the downward movement restricting projection portion 28A. That is, when the slide switch 71 is in the right position, even if the seesaw switch 72 is pressed, the hook portion 72a contacts the downward movement restricting projection portion 28A and does not rotate. Therefore, even if an unexpected external force is applied to the outer cylinder 10, the outer cylinder 10 does not move down, and therefore an inadvertent marking operation can be prevented.

  FIG. 22 is a longitudinal sectional view of a locking mechanism according to another embodiment. FIG. 22 also shows that the slide switch 71 is operated to the right position (see FIG. 20B) when the stamp surface 32 is stored in the inner cylinder 20 (the inner cylinder 20 is in the protruding state and the opening / closing lid 40 is in the closed state). The state where the downward movement of the cylinder 10 is locked is shown. In this embodiment, the bending hook portion 72b of the seesaw switch 72 is engaged with the bending protrusion 28B provided on the inner cylinder 20, whereby the rotation of the seesaw switch 72 is more firmly regulated. Therefore, the locked state between the outer cylinder 10 and the inner cylinder 20 is maintained more firmly.

  In the two embodiments described above, by operating the slide switch 71 to the right position (see FIG. 20A), the hook portion 72a and the downward movement restricting projection portion 28A or the bending projection portion 28B are unlocked. The movable lock is released.

  Next, FIG. 23 shows that the upward movement of the outer cylinder 10 is locked at a position where the outer cylinder 10 is moved downward and the marking surface 32 is exposed from the inner cylinder 20 (the inner cylinder 20 is in a retracted state and the opening / closing lid 40 is in an opened state). It shows the state that was done. In this case, as shown in the figure, the upward movement of the outer cylinder 10 is restricted by the hook portion 72a of the seesaw switch 72 being blocked by the upward movement restricting projection 27 provided on the inner cylinder 20. Therefore, the user can easily take out the ink pad container 50 while maintaining the open state of the opening / closing lid 40 by operating this lock mechanism, and can easily replace the ink pad 60 or refill ink. .

  In the present embodiment, in the state where the upward movement of the outer cylinder 10 shown in FIG. 23 is locked, the seesaw switch 72 can be rotated regardless of the position of the slide switch 71. That is, the user can easily release the upper lock of the outer cylinder 10 by pressing the seesaw switch 72.
