Hereinafter, the stamp 1 according to the preferred embodiment of the present invention will be described with reference to the drawings. The stamp 1 has a cylindrical outer cylinder 10, a similarly cylindrical inner cylinder 20, and an opening / closing lid 40 adapted to open and close in conjunction with a sliding movement between the outer cylinder 10 and the inner cylinder 20. I have. A part of the inner cylinder 20 (upper part in the drawing) is housed in the outer cylinder 10 so as to be slidable. A coil spring 34 is provided in the outer cylinder 10, and the coil spring 34 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. A window portion 11 having an opening is formed on the front portion of the outer cylinder 10. When the inner cylinder 20 is degenerated most into the outer cylinder 10, the date number such as the date of the date stamp is changed through the window portion 11 of the outer cylinder 10 and the window portion 21 of the inner cylinder 20 described later. The dial 61 can be operated. According to the stamp 1 of the present embodiment, as will be described later, the inner cylinder 20 can be retracted and the stamp surface can be locked from the inner cylinder 20 by a simple operation. The user of the stamp 1 can easily change the date number of the date stamp by rotating the dial 61 while keeping the stamp surface exposed from the inner cylinder 20.

Further, the outer cylinder 10 may be provided with a lock operation unit 81 for locking the slide movement of the inner cylinder 20. The lock operation unit 81 can be, for example, a slide switch provided above the window unit 11.

Further, a crown 71 for changing the number of the date mark on a daily basis may be provided on the side surface of the outer cylinder 10.

Cam holes 12a and 12b are provided on the side surface of the outer cylinder 10 to guide the follower shaft portion 43 of the opening / closing lid 40 following the sliding movement of the inner cylinder 20. Further, a groove hole portion 12c is continuously provided at the upper end of the cam hole portion 12b. For example, as shown in FIG. 2, the groove hole portion 12c has a groove shape that is perpendicular to or at an acute angle with respect to the length of the cam hole portion 12b and is bent from the upper end of the cam hole portion 12b in the circumferential direction of the outer cylinder 10. ing. That is, the groove hole portion 12c is provided so that the follower shaft portion 43 of the opening / closing lid 40 is engaged at the position where the inner cylinder 20 is most retracted in the outer cylinder 10. As a result, a locking mechanism for locking the slide movement between the outer cylinder 10 and the inner cylinder 20 is configured (see, for example, FIG. 7).

The inner cylinder 20 is made of a substantially cylindrical hollow member having an opening at the lower end portion 20a for exposing the stamp surface. The outer diameter of the inner cylinder 20 corresponds to the inner diameter of the outer cylinder 10 described above, and 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. A window portion 21 having an opening is formed on the front portion of the inner cylinder 20. A cam hole portion 22 for guiding the follower shaft portion 43 of the opening / closing lid 40 is provided on the side surface portion of the inner cylinder 20.

The opening / closing lid 40 is rotatably attached to the inner cylinder 20, and a tray-shaped ink pad accommodating portion 41 is integrally formed at the opening / closing end portion thereof. The ink pad accommodating portion 41 accommodates an ink pad 42 impregnated with ink.

As the material of the ink pad 42, for example, polyolefin fibers made of polyethylene (PE) and polypropylene (PP) can be used. The ink impregnated in the ink pad 42 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, or the like is dissolved and mixed in a quick-drying solvent. it can.

The follower shaft portion 43 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, the follower shaft portion 43 of the opening / closing lid 40 is restrained in the hole portion where the cam hole portion 12a or 12b and the cam hole portion 22 having a shape as shown in FIG. 2, for example, intersect. It is equipped with a cam mechanism. By such a cam mechanism, the opening / closing lid 40 is configured to rotate to the opening side according to the downward movement of the outer cylinder 10, and conversely to the closing side according to the upward movement of the outer cylinder 10.

The stamp 1 includes a print body holder 30 that fits and holds a print body 31 having a stamp surface 32 inside the outer cylinder 10 and the inner cylinder 20. For example, as shown in the cross-sectional views of FIGS. 3 and 4, a columnar portion 33 extends above the printed body holder 30. The upper end of the columnar portion 33 is connected to the top plate portion 13 of the outer cylinder 10.

The print holder 30 of the present embodiment is provided with a date number changing mechanism having a belt on which each number string corresponding to the date of the date stamp is engraved. Each belt is wound around the shaft of the corresponding dial 61. That is, by rotating the dial 61, it is possible to change the marking of the date number displayed on the stamp surface 32.

In the stamp 1 of the present embodiment, the coil spring 34 housed in the outer cylinder 10 in a compressed state gives an elastic force to the inner cylinder 20, so that the inner cylinder 20 protrudes from the outer cylinder 10 when not in use. It has become. In this state, the opening / closing lid 40 closes the opening of the lower end portion 20a of the inner cylinder 20, and the ink pad 42 housed in the ink pad accommodating portion 41 of the opening / closing lid 40 faces the stamp surface 32 of the printing body 31. .. As a result, ink is supplied to the stamp surface 32.

In the stamping by the stamp 1, as shown in FIGS. 5 and 6, the outer cylinder 10 is moved downward by pressing the lower end portion 20a 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 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 34. In conjunction with this, the opening / closing lid 40 closes to the inner cylinder 20 side.

Further, the stamp 1 according to the present embodiment is provided with a lock mechanism for holding the opening / closing lid 40 in the fully open position with the stamp surface 32 of the printing body 31 exposed from the inner cylinder 20. With this locking mechanism, for example, as shown in FIG. 7, the movements of the inner cylinder 20 and the opening / closing lid 40 can be locked at the same time. Specifically, this locking mechanism includes a groove hole portion 12c connected to the upper end of the cam hole portion 12b that guides the follower shaft portion 43 of the opening / closing lid 40. The follower shaft portion 43 can be easily engaged with the groove hole portion 12c by slightly rotating the opening / closing lid 40 outward at the position where the inner cylinder 20 is most retracted in the outer cylinder 10.

Further, the groove hole portion 12c preferably has a groove shape that is perpendicular to or at an acute angle with respect to the length of the cam hole portion 12b and is bent from the upper end of the cam hole portion 12b in the circumferential direction of the outer cylinder 10. According to this configuration, the elastic force of the coil spring 34 acting on the inner cylinder 20 acts to move the follower shaft portion 43 to the back of the groove portion 12c at the same time. Therefore, the opening / closing lid 40 can be more reliably held in the fully open position.

When the follower shaft portion 43 engages with the groove hole portion 12c, the opening / closing lid 40 can be fully opened and the stamp surface 32 can be held in a state of being exposed from the inner cylinder 20. Therefore, the user can visually check the stamp surface 32, change the date number while looking at the stamp surface 32 of the date stamp, and replace the printing body 31 while locking the movements of the opening / closing lid 40 and the inner cylinder 20. Etc. can be easily performed.

The stamp 1 may be provided with a removable cap 50 with a lens on both the head portion of the outer cylinder 10 and the lower end portion 20a of the inner cylinder 20. When the cap 50 with a lens is fitted to the head of the outer cylinder 10, the user can easily see the enlarged stamp surface display plate 15 through the lens 51 (see FIGS. 3 and 4). ). Further, when visually checking the stamp surface or changing the date number of the date stamp, the cap 50 with a lens can be fitted to the lower end portion 20a of the inner cylinder 20 as shown in FIG. 8, for example. As a result, the user can easily see the enlarged stamp surface 32 through the lens 51.
