Description

[Detailed Description of the Invention] [Technical Field and Purpose] This invention relates to a rotary stamp whose direction of stamping can be easily determined.

[Background technology]

In the date stamp shown in FIGS. 1 and 2, a handle 23 is bolted onto the main body case 1. It has a fixed printing body 13 at the lower end of the main body case 1, and a rotary printing mechanism 4 inside the main body case 1.
variable printing surface 9 at the lower end of the rotary printing mechanism 4.
This is to adjust the height so that a is flush with the fixed printing surface 13a. That is, the handle 23 is screwed onto the bolt 19 on the main body case 1. Therefore, the handle 2 to be bolted
3 cannot be provided with front indicator means. For this reason, in the past, an index had to be displayed on the side of the main body case 1, but this made it difficult to see the lower index, and the current situation was to turn the date stamp upside down and look at the printed surface each time to confirm the direction of the stamp. In addition to being troublesome, the seal impression was often upside down.

This kind of problem also applies to the number marks, etc., where the handle 23 is simply screwed onto the upper part of the main body case 1 for ease of assembly.

[Purpose and outline of the invention]

Focusing on this fact, this invention improves usability by providing a front indicator on the handle that is easy to see even from above when stamping, and also allows the height of the variable print surface to be adjusted relative to the fixed print surface. Even if the final rotational stop position is not constant, the indicator can be easily adjusted in the correct forward direction at all times.

〔Example〕

Endless printing belts 9 are strung across from side to side, and each dial 8 is exposed to the outside through each slit 10 on the front and rear sides of main body case 1, and each printing belt 9 is manually fed and rotated by turning each dial 8. The structure is such that it can be done.

The lower sliding frame 3 is erected on left and right guide side plates 3a, 3a, and the guide side plates 3a, 3a fit into the outer periphery of the lower opening of the main body case 1. Main case 1
A long hole 11a is formed in the lower part of each side of the left and right sides, and a pin receiving hole 11b is formed in each of the guide side plates 3a and 3a, and a support pin 12 is passed through between the long hole 11a and the pin receiving hole 11b. The lower sliding frame 3 is fixed at the lower part of the main body case 1 via this support pin 12.
is inserted and supported so that it can move up and down by a predetermined stroke. A printed body 13 is fixed to the lower surface of the sliding frame 3, and the lower end of the printing belt 9 projects into the central opening 14 of the printed body 13.

A circular through hole 17 is provided in the center of the top plate 16 of the main body case 1, and a blind hole 18 is also provided in the fixed frame 2 fitted over the top plate 16, concentrically with the through hole 17. A bolt 19 is fixed and erected on the top surface of the gate frame 5, and the bolt 19 is passed through the through hole 17 and the blank hole 18 to protrude above the main body case 1, and is screwed into the bolt 19. The outer peripheral groove of the square adjustment nut 20 is rotatably engaged with the inner peripheral edge of the through hole 17 in a manner that prevents it from coming off.

Thus, the circular operation plate 22 is fitted into the square part above the outer circumferential groove of the adjustment nut 20 in a non-rotating manner, and the operation plate 22 is stacked on the square frame 2, and the operation plate 2
2 to turn the adjustment nut 20,
The variable printing surface 9a at the lower end of the printing belt 9 is made to protrude into the central opening 14 of the printing body 13.
The height is adjusted so that it is flush with the fixed printing surface 13a.

A handle 23 for holding the main body case 1 is vertically hollow, and is attached to the main body case 1 by screwing a female screw 25 provided on the lower side of the inside into the bolt 19.

This invention is based on the above-mentioned structure of the rotary sign.
It is characterized in that a front indicator tube 29 is provided on the upper outer periphery of the tube.

That is, a step 27 is attached to the upper and lower center of the outer periphery of the handle 23, and the upper handle outer periphery 23a above the step 27 is formed to have a smaller diameter than the lower outer periphery 23b below the step 27. A female thread 28 is provided on the inner periphery of the upper end of the opening of 23. An entry form 26 for writing the user name, department name, etc. is wrapped around the upper outer circumference 23a,
On the outside is a transparent plastic circular indicator tube 29.
is inserted from above the handle 23 so as to be rotatable around the handle axis, and the threaded part 30a of the presser cap 30 with a head is screwed into the upper end opening of the handle 23, and the head 30b of the presser cap 30 is seated. The index tube 29 is fixed in a manner to prevent it from falling upward and from rotating at the surface 30c. A front indicator 31 is integrally provided on a part of the outer surface of the indicator cylinder 29 in the circumferential direction and projects in the direction of the handle axis.

With the rotation mark configured in this way, when the handle 23 is finally screwed onto the bolt 19 during assembly, the rotation printing mechanism 4 can be turned by rotating the adjustment nut 20 by rotating the operation plate 22 in the hand. The height is adjusted so that the fixed printing surface 13a and the variable printing surface 9a are flush with each other. Then, the handle 23 is fully screwed into the bolt 19, and the lower end of the handle 23 presses the operation plate 22 onto the main body case 1, so that it is clamped and fixed so as not to rotate. After that, presser foot cap 30
The front indicator 31 is properly positioned on the front side of the main body case 1 by loosening the tightening once and rotating the index tube 29 around the shaft axis, and then firmly tightening the presser cap 30 to prevent the index tube 29 from rotating. fixed in shape.

At this time, the variable printing surface 9a is predetermined, but the fixed printing surface 13a is ordered differently depending on the user, so the printing body 13 is fixed to the lower surface of the lower sliding frame 3 later. Therefore, this printed body 1
3 is fixed, it is necessary for the user to make a final height adjustment of the variable printing surface 9a to be attached to the fixed printing surface 13a according to the thickness of the printing body 13, etc. Rotary printing mechanism 4 even when using the rotary mark
It is necessary to make fine adjustments again so that the fixed printing surface 13a and the variable printing surface 9a are flush with each other due to backlash occurring in each part.

Even in such a case, with the rotary stamp of the present invention, even if the handle 23 is slightly returned and rotated, the operating plate 22 is rotated to adjust the height of the rotary printing mechanism 4, and the handle 23 is tightened again, the presser foot will not work. By slightly loosening the cap 30, the front indicator 31 of the indicator tube 29 can be adjusted to the correct rotational direction to the front position of the main body case 1. After the direction adjustment, the presser cap 3
Simply tighten the index cylinder 29 against the handle 23.
can be securely fixed.

[Another Embodiment] Although the entire details of the embodiments shown in FIGS. 1 to 4 are as described above, the present invention is not limited thereto. For example, as a means for fitting the presser cap 30 onto the upper end of the handle 23, as shown in FIG. Recess 32
It may also be made to fit. In addition, the indicator tube 29
In order to form the front indicator 31 to protrude, the front indicator 31 may be formed to protrude on the outer surface of the indicator tube 29 with the thickness of the indicator tube 29, as shown in FIG. Further, the front indicator 31 may have a concave shape instead of a convex shape, and the front indicator 31 formed in a convex or concave shape may be colored, or the outer surface of the indicator tube 29 may be simply colored. The front indicator 31 may be configured with the following.

Furthermore, if the indicator cylinder 29 is made transparent, the user name, department name, etc. written on the entry form 26 can be seen through from the outside, but it is also possible to make the entry form 26 unnecessary, and in such a case Alternatively, the index cylinder 29 may be made of an opaque body. Furthermore, in the illustrated example, the rotary printing mechanism 4 is a date stamp that moves up and down within the main body case, but in the present invention, the rotary printing mechanism 4 is fixed to the main body case 1, such as a number mark, and the handle 23 is screwed. It can also be widely applied to other forms.

[Effect of idea]

As explained above, according to this invention, in the rotary mark in which the handle 23 is screwed into the bolt 19 at the upper part of the main body case 1 that incorporates the rotary printing mechanism 4, the handle 2
