Description

[Detailed description of the invention] (a) Industrial application field This invention relates to various stamps, such as date stamps, which are used, for example, to affix a seal with a date in general office work.

(b) Prior art and its problems With conventional stamps, if the stamp is placed carelessly on a desk, etc., the direction of the printed part will not be consistent. It is a hassle to have to check. This confirmation procedure is troublesome, especially in businesses where seals are frequently stamped, and as a result of stamping without checking the direction of the printed portion, there has been a problem that the printed text may be upside down.

(c) Means for solving the problem In order to solve the above problem, the stamp according to this invention has a stable part at one place on the periphery near the printing part provided on the main body, and the stable part is fixed by the action of gravity. A guide body with a rolling curved surface that generates a rotational force toward .

(d) Effect As the guide body is fixed as mentioned above, even if the stamp is placed casually on a desk, etc., the stamp will roll due to the gravity applied to it until the stable part comes into contact with the top of the desk, and the printing part will roll. Always stable when facing in a certain direction.

(E) Embodiment FIG. 1 is a perspective view of a stamp according to an embodiment of this invention. Further, FIG. 2a is a perspective view of the inner body 50 shown in FIG. 1, and FIG. 2b is a side view of the guide body 50.

As shown in FIG. 1, the stamp according to this embodiment is roughly divided into a printing part 10 formed on the tip end surface of the stamp, a sliding frame 20 to which the printing part 10 is attached, and a sliding frame 20 attached to the sliding frame 20. It is composed of a main body frame 30 that fits together, a handle 40 connected to the main body frame 30, and a guide body 50 that is attached to the sliding frame 2 and supports the stamp in a rotatable manner together with the handle 40. There is.

The feature of this embodiment is that the guide body 50
For convenience of explanation, the other components will be outlined first, and then the guide body 50 and its function will be explained.

The printing unit 10 includes a circular rubber stamp 11 with printed characters engraved on the upper and lower ends and a horizontally long rectangular opening in the center, and a rubber stamp 12 for printing a date arranged in the opening. . Circular rubber stamp 1
1 is adhered and fixed to the outer surface of the base of a U-shaped sliding frame 20 that is slidably fitted to the main body frame 30. On the other hand, the rubber stamp 12 for printing the date is divided into segments each displaying the year, month, and day, and the rubber stamp 12 constituting each segment has a ring shape. Numbers indicating the year, month, and day are sequentially carved along the outer circumferential surface of each rubber stamp 12.

The main body frame 30, to which the sliding frame 20 is slidably fitted on one end side, has a cylindrical shape with a substantially square cross section, and the rubber stamp 12 for printing the date is placed inside the main body frame 30. It houses a drive mechanism (not shown) that rotates. A plurality of date changing gears 31 are arranged in parallel to move the rubber stamps 12 of each segment in conjunction with this drive mechanism, and a part of them is led out to the side surface of the main body frame 30.

Therefore, the date change is performed in the following steps. That is, by rotating the date changing gear 31 with the sliding frame 20 pulled out, an arbitrary date can be placed on the printing section 10. After that, the sliding frame 20 is pushed into the main body frame 30 and the bolts, which are not shown in the figure, are fitted so as to pass through the main body frame 30 and the sliding frame 20. 20 is fixed.

The handle 40 connected to the main body frame 30 is formed of a rod-shaped body with a circular cross-section and a diameter that increases toward the distal end.

As shown in FIG. 2, the guide body 50 is a biased curved surface formed by combining biased curvature circles with different radii, that is, a substantially oval plate-like body, and has a predetermined leg portion 51a at one location on its periphery. A stable portion 51 consisting of a recess 51b is formed, and a rolling curved surface portion 60 that is symmetrical with respect to the center line of the stable portion 51 is formed on the periphery excluding the stable portion 51. This guide body 50 has a stable portion 51 thereof.
A rectangular opening 52 for fitting into the frame is provided adjacent to the frame. In addition, to make it easier to see the stamped paper and further improve work efficiency,
An arc-shaped notch 53 is provided on the side that faces the stable portion 51 among the sides forming the opening 52, but this notch 53 is not necessarily provided when the guide body 50 is made of transparent synthetic resin. Not necessary. Furthermore, a pair of protrusions 54 for screwing are formed on one side of the guide body 50 so as to sandwich the opening 52 from the left and right in the figure, and a small hole through which a tightening bolt is passed is formed at the tip of the protrusion 54. 55 have been established. Thus, the sliding frame 20 is inserted into the opening 52 of the guide body 50 so that the protruding piece 54 faces toward the handle portion 40 side. Then, a bolt for fixing the sliding frame 20 and the main body frame 30 described above is inserted into the small hole 55 of the projection piece 54, and by tightening this bolt, the guide body 50 is attached to the manual frame 2.
Attached to 0.

Next, the effect when the stamp having the above-described configuration is placed on a desk, for example, will be explained.

When the stamp shown in FIG. 1 is placed on a desk, the stamp is supported by the tip of the handle 40 and the rolling curved surface 60 of the guide 50. FIG. 3 is a view of the guide body 50 with the stamp placed thereon. In the figure, the rectangular shape indicated by the chain line indicates the opening 52, and the intersection G of the diagonal lines thereof indicates the center of gravity of the guide body 50 when it is fixed to the stamp on which the weight W acts. Assume that the stamp is placed so that the stable portion 51 of the guide body 50 is on the right side as shown in FIG. At this time, the guide body 5
The distance from the point of contact between 0 and the desk to the line of action of weight W is
When expressed as L1, this support plate 50 has a size W×
Couple M acts on L1 as a clockwise turning force.
As a result, the stamp, which is rotatably supported by the tip of the handle portion 40 and the rolling curved surface portion 60 of the guide body 50, rolls clockwise. However, as shown in Figure b, when the guide part comes into contact with the desk, the guide body 5
Since the couple no longer acts on 0, the stamp becomes stable in this state. Similarly, when the stamp is placed so that the guide portion 51 is on the left side as shown in FIG. As a result, the stamp rolls to the left. Thus, the stamp is stabilized in a state where the guide portion 51 is in contact with the desk as shown in FIG. 5B. During these rolling operations, as shown in FIG.
If the concave portion 51b is formed in the intermediate portion, the stable portion 51 and the desk come into contact with each other and are supported at two points by the stable leg portions 51a, so that the desk does not swing before being stabilized regardless of the flatness of the top surface.

In addition, in the explanation of the above-mentioned embodiment, a separately formed plate-shaped guide body 50 was attached to the stamp sliding frame 20 in consideration of manufacturing convenience, but this guide body is attached to the stamp handle or the frame itself. It may be a three-dimensional object formed integrally with the stamp by processing the stamp. Also, the rolling curved surface portion 6
0 is not limited to a substantially oval shape, and even if it is a circumferential surface, rolling action as in this example can be expected, but if the printed part is placed on a desk in a position where the direction is completely opposite to the predetermined direction. In this case, a roughly oval shape will reach a stable state more quickly.

(f) Effect The stamp according to this invention has a guide that has a stable part at one point on the periphery near the printing part of the main body, and a rolling curved part that generates rotational force from the direction of the stable part by the action of gravity. Even if the stamp is placed casually on the desk after the body is fixed, the stamp will roll due to the couple of forces generated around the guide body, and the stamp will remain in a stable position with the printing part always facing a certain direction.

Therefore, according to this invention, when affixing a seal, one only has to casually hold the object in a stable state, and there is no need to check the direction of the printing part each time, which improves office efficiency, and also makes it possible to print the stamp upside down. It is possible to eliminate the mistake of stamping.
