Hereinafter, the stamp 1 according to the preferred embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 5, the stamp 1 is interlocked with the slide movement between the square tubular outer cylinder 10, the square tubular inner cylinder 20, and the outer cylinder 10 and the inner cylinder 20. It is provided with an opening / closing lid 40 adapted to open / close. A part of the inner cylinder 20 (upper part in the drawing) is housed so as to be slidable with respect to the outer cylinder 10. A coil spring (not shown) is provided in the outer cylinder 10, and the coil spring constantly urges the inner cylinder 20 in the protruding direction.

The outer cylinder 10 is a member that constitutes the main body of the stamp 1 and also functions as a handle portion (grip) for stamping. For example, as shown in FIG. 2, cam holes 12a and 12b for guiding the follower shaft portion 45 of the opening / closing lid 40 are provided on the side surface portion of the outer cylinder 10 so as to follow the slide movement of the inner cylinder 20.

Further, as shown in FIG. 3, for example, a lock operation portion 70 of a lock mechanism adapted to lock the slide movement of the outer cylinder 10 with respect to the inner cylinder 20 is provided on the back surface portion of the outer cylinder 10. The lock operation unit 70 includes a seesaw switch 72 and a slide switch 71 for laterally moving the seesaw switch 72.

The inner cylinder 20 is made of a hollow member having a substantially square cylinder shape having an opening at the lower end portion 20a for exposing the stamp surface. The upper portion of the inner cylinder 20 is inserted so as to be slidable from the lower open portion of the outer cylinder 10. For example, as shown in FIG. 6, an opening portion 23 adapted to be closed by the opening / closing lid 40 is formed in the lower part of the front surface of the inner cylinder 20. The top plate portion of the inner cylinder 20 is formed with an opening 24 fitted so that the printed body 30 penetrates. A cam hole portion 22 for guiding the follower shaft portion 45 of the opening / closing lid 40 is provided on the side surface portion of the inner cylinder 20. A guide portion 25 for guiding the slide movement in the outer cylinder 10 is formed on the upper part of the front surface of the inner cylinder 20.

The details will be described later, but on the back surface of the inner cylinder 20, the seesaw switch 72 is locked to regulate the upward movement of the outer cylinder 10 and the upward movement regulating protrusion 27 for restricting the upward movement of the outer cylinder 10. A lower movement regulating protrusion 28A is formed for this purpose. The seesaw switch 72, the upward movement restricting protrusion 27, the downward movement restricting protrusion 28A, and the like constitute the locking mechanism of the stamp 1 according to the present embodiment.

The stamp 1 stores a printing body 30 having a stamp surface 32 inside the inner cylinder 20. The printed body 30 has a substantially columnar shape. For example, as shown in the cross-sectional views of FIGS. 4 and 5, the printed body 30 penetrates the opening 24 of the inner cylinder 20 and is supported by the top plate portion of the outer cylinder 10. As a result, 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 penetrates 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 the present 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. 6 intersect. 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 toward the opening side as the outer cylinder 10 moves downward into the inner cylinder 20, and conversely moves toward the closing side as the outer cylinder 10 moves upward from the inner cylinder 20. It is configured to rotate. Then, at the position where the inner cylinder 20 protrudes most from the outer cylinder 10, the stamp surface on the lower surface of the printing body 30 is closed by the opening / closing lid 40. As a result, the ink pad 60 held by the opening / closing lid 40 abuts against the stamp surface 32, and the ink is supplied to the stamp 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 portion 41 having a rectangular opening 44 formed therein, a follower shaft portion 45 formed on an arm portion extending from the upper end of the front portion 41, and an ink described later. It is a member in which each part including notch plate parts 42L and 42R (container holding part) for holding the pad container 50 detachably is integrally formed.

In the present embodiment, the ink pad 60 that supplies ink to the stamp surface 32 of the printing body 30 is housed in, for example, the ink pad container 50 shown in FIGS. 12 and 13. Then, the ink pad container 50 is removably held in the container holding portion formed on the opening / closing lid 40.

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 notch plate portions 42L and 42R. The notch plate portions 42L and 42R are separated by a notch in the center, 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 each other from the tip to the inside. There is. That is, the first groove portion 43a and the second groove portion 43b are formed by arranging the first groove portion 43a and the second groove portion 43b from the tip to the inside along the notch edges of the notch plate portions 42L and 42R by these protrusions. As shown in FIG. 11, the container holding portion is narrowed by the first protrusions 42a and 42a in which the notch insertion openings between the notch plate portions 42L and 42R are projected from both tips so as to face each other. Is preferably formed.

As shown in FIGS. 12 and 13, for example, the ink pad container 50 has a bottomed cylindrical pad accommodating portion 52 having an opening on the lower side and a substantially semicircular parallel plate on the upper surface side of the pad accommodating portion 52. It is a member in which each portion including a knob portion 53 having a knob portion 53 and a substantially semicircular top 51 projecting from the front surface side of the pad accommodating portion 52 is integrally formed. The ink pad container 50 is further formed with a substantially semicircular protrusion-shaped first fitting portion 54a and a second fitting portion 54b on both sides of the neck portion between the pad accommodating portion 52 and the knob portion 53.

The ink pad 60 (see FIGS. 4 and 5) is housed in the pad accommodating portion 52 of the ink pad container 50. As the material of the ink pad 60, for example, polyolefin fibers made of polyethylene (PE) and polypropylene (PP) can be used. The ink impregnated in the ink pad 60 can be appropriately used regardless of whether it is a pigment-based ink, a dye-based ink, an oil-based ink, or an aqueous ink-based ink. For example, as a quick-drying ink for stamping on non-absorbent paper such as coated paper, plastic film, aluminum, iron, etc., it is possible to use an oil-based ink in which a colorant, a resin, etc. are dissolved and mixed in a quick-drying solvent. it can.

In the present embodiment, the ink pad container 50 is removably held in a container holding portion formed on the opening / closing lid 40 (FIG. 17A). Further, the container holding portion provided on the opening / closing lid 40 has a set position (FIG. 17C) in which the ink pad 60 can face the stamp surface 32 and a preset position (FIG. 17B) slightly offset to the outside of the set position. The ink pad container 50 is configured to be fitted and held in the above.

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 into the one groove portion 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 pushed further inward, 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 portion is fitted. The joint portion 54b fits into the first groove portion 43a. As a result, 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 accidentally pop out. Further, when the opening / closing lid 40 is opened, there is no possibility that the ink pad container 50 will fall. Further, since the ink pad container 50 can be detachably taken out from the opening / closing lid 40, it is possible to easily perform operations such as replacement of the ink pad 60 and replenishment of ink to the ink pad 60 having a reduced ink storage amount. it can.

Further, in the stamp 1 of the present embodiment, the coil spring housed in the outer cylinder 10 in a compressed state gives the inner cylinder 20 an elastic force, 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 housed in the ink pad container 50 of the opening / closing lid 40 is stored in the inner cylinder 20 of the printing body 31. It abuts against the stamp surface 32. As a result, ink is supplied to the stamp surface 32.

When stamping with the stamp 1, as shown in FIGS. 7 to 9, the lower end portion 20a of the inner cylinder 20 is applied to the paper surface, and the outer cylinder 10 is pressed toward the paper surface to move the outer cylinder 10 downward. In conjunction with this, the opening / closing lid 40 opens outward. When a pressing force is further applied to the outer cylinder 10, the stamp surface 32 of the descending printing body 31 is exposed from the lower end portion 20a of the inner cylinder 20, and the stamp surface 32 comes into contact with the paper surface, so that the imprint is transferred to the paper surface.

When the pressure on the outer cylinder 10 is released after the stamping is completed, the inner cylinder 20 returns to the initial protruding position due to 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 locking mechanism provided in the stamp 1 of the present embodiment and adapted to lock the slide movement of the outer cylinder 10 with respect to the inner cylinder 20 will be described. This lock mechanism includes a seesaw switch 72 for locking and unlocking the slide movement of the outer cylinder 10, and a slide switch 71 configured to move the seesaw switch 72 to the left and right.

FIG. 18 shows a perspective view of the slide switch 71. The slide switch 71 has an opening 71a in which the seesaw switch 72 is fitted in the center of the square plate-shaped main body. Bearing portions 71b for receiving the rotation shaft portion 72b of the seesaw switch 72 are formed on the left and right back surfaces of the opening portion 71a. Further, a locking portion 71c for slidably locking the outer cylinder 10 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 having a substantially L-shape in appearance. The seesaw switch 72 is formed with a hook portion 72a that projects rearward from the lower part of the main body. On the left and right surfaces of the main body, rotating shaft portions 72b that are pivotally supported by the bearing portion 71b of the slide switch 71 described above are extended. Further, a protrusion 72c for hanging a finger is formed on the upper part of the front surface of the main body so that the user can easily perform the pressing operation.

The lock operation unit 70 is provided on the back surface of the outer cylinder 10, that is, the surface opposite to the opening lid 40, in which the seesaw switch 72 is fitted in the opening 71a of the slide switch 71. As shown in FIGS. 20A and 20B, the lock operation unit 70 is configured so 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 vertical cross-sectional views showing an embodiment of a lock mechanism adapted to lock the slide movement of the outer cylinder 10 with respect to the inner cylinder 20. As shown in these figures, the seesaw switch 72 is constantly urged in the direction in which the hook portion 72a enters the inner cylinder 20 side by the elastic force of the leaf spring portion 15 integrally provided on the outer cylinder 10. ing.

In FIG. 21, the slide switch 71 is operated to the right position (see FIG. 20B) in the storage position where 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), and the outside It shows a state in which the downward movement of the cylinder 10 is locked. In this case, as shown in the figure, the hook portion 72a of the seesaw switch 72 is blocked by the lower movement restricting protrusion 28A provided on the inner cylinder 20, so that the lower movement of the outer cylinder 10 and the seesaw switch 72 Unlock operation is regulated 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 protrusion 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 comes into contact with the downward movement restricting protrusion 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 downward, and therefore an inadvertent marking operation can be prevented.

Further, FIG. 22 is a vertical cross-sectional view of the locking mechanism according to another embodiment. Also in FIG. 22, the slide switch 71 is operated to the right position (see FIG. 20B) in the storage position where 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), and the outside It shows a state in which the downward movement of the cylinder 10 is locked. In this embodiment, the bending hook portion 72b of the seesaw switch 72 meshes with the bending protrusion 28B provided on the inner cylinder 20, so that the rotation of the seesaw switch 72 is further strictly regulated. Therefore, the locked state between the outer cylinder 10 and the inner cylinder 20 is maintained more firmly.

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

Next, in FIG. 23, the upward movement of the outer cylinder 10 is locked at the position where the outer cylinder 10 moves downward and the stamp surface 32 is exposed from the inner cylinder 20 (the inner cylinder 20 is in the retracted state and the opening / closing lid 40 is in the open state). It shows the degenerate state. 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 protrusion 27 provided on the inner cylinder 20. Therefore, by activating this lock mechanism, the user can take out the ink pad container 50 while maintaining the open state of the opening / closing lid 40, and facilitate replacement of the ink pad 60, replenishment of ink, and the like. ..

Further, 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 upward lock of the outer cylinder 10 by pressing the seesaw switch 72.
