Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stamping device suitable for a so-called penetration type rubber stamp.

[0002]

[Prior art]

 Ink-penetrable rubber stamps having a marking surface made up of letters, numbers, symbols, etc. are well known and are well-received because a clear seal impression can be obtained. However, since the printing pressure, that is, the pressing force differs from pressing to pressing, and the pressure cannot be controlled, there is a problem that a clear imprint cannot always be obtained. In particular, if there is a space between prints, there is a drawback in that even if the space is pressed too much, the space portion may still contact the pressing surface.

Further, in the conventional ink permeation type rubber stamp, the printing pressure is constant from the beginning. In other words, the pressure is set to be the optimum pressure when manufacturing the immersion rubber stamp, but this requires extremely strict control of the character height (character depth) and total thickness, which requires a lot of time and cost. It has been beaten.

If the imprint changes depending on the printing method, that is, the printing pressure, an excessive amount of ink is supplied to the printing surface with a multiple of an appropriate amount of ink, causing “bleeding” due to excess ink. Make the imprint unclear. For this reason, conventionally, there has been a drawback that the accuracy of reading a computer such as an OCR character is affected and reliability is lowered.

[0005]

[Problems to be solved by the device]

 The present invention has been made by paying attention to the above points, and its problem is that no matter how or how the imprinting operation is performed, a certain imprinting result can be obtained, and the imprint is always clear to improve the computer reading accuracy. % Reliability is to be obtained.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention has a main body 2 which also serves as a holder for a pressing operation, has an opening 1 at one end which is in contact with the pressing surface at the time of pressing, and a stamped surface 3 on which printing is performed. The printing body 4 is disposed in the opening 1 so that the printing surface 3 can be printed by the printing body 4, and the printing body 4 is provided along both sides of the printing body 4 so as to be retractable from the opening 1. When the printing is not performed, the printing body 4 projects from the printing surface 3 and is printed. A stamping device having a pair of side plates 5 provided on the main body 2 so as to be slidable inward when pressed, is provided with a support shaft 6 for supporting a printing pressure applied to the printing body 4 during printing. A means for mounting a spring force adjusting mechanism, which is provided slidably inside and which adjusts the expansion and contraction amount of the supporting spring 7 which applies a printing pressure to the stamp surface 3 at the time of pressing, to the support shaft 6 is provided.

【Example】

 A description will be given below with reference to the drawings.

The main body 2 is formed in a hollow flat case type, and also functions as a holder that is held by one hand for a pushing operation. The lower end of the main body 2 is an elongated opening 1, and the end portion 1a thereof contacts the imprinting surface P during embossing (FIG. 5C). 1b is an intermediate cutout of the end 1a, so that the end 1a is located at both ends of the elongated opening 1.

A stamp surface 3 made up of a combination of the prints 3a and the like is formed on the lower surface of the print body 4, and the stamp surface 3 is arranged in the opening 1 to form a seal impression by a stamping operation. 3b shows a space between the prints 3a (FIG. 1). The space 3b is, of course, dented from the print 3a, but may be on the same plane as the lower end 4a of the print body 4.

The printing body 4 is a permeation type rubber stamp in which an ink reservoir 8 capable of impregnating ink is integrally provided on the back of a member provided with a printing surface 3, and the ink is printed through a rubber material having open cells. It has a structure that supplies up to the stamp surface.

The printing body 4 is integrally assembled to the lower end of a holding body 10 having a replenishing hole 9 for replenishing the ink reservoir 8 with ink, and is vertically movable together with the holding body 10 in the main body. Incorporated.

That is, the holder 10 has a central main support shaft 6 and left and right guide support shafts 6 ′ and 6 ′. The main spindle 6 is fitted in a hole 12 of a support portion 11 formed in the main body and can move up and down. A male screw portion 13 is formed at the upper end of the main spindle, and is attached to the lower portion of the support portion 11. Double nuts 14 and 15 that allow the holder 10 to be vertically adjusted against the main support spring 7 are screwed into the male thread 13 on the upper side to form a spring force adjusting mechanism. The guide shafts 6 ', 6'are inserted into the guide holes of the guide portions 16, 16 formed on the left and right sides of the main body to prevent the stamp face 3 from swinging.

In this way, the holder 10 incorporated in the main body 1 is urged by the support spring 7 provided on the main support shaft 6 in the direction in which the stamp surface 3 projects from the opening end portion 1a. Similar auxiliary support springs 7 ', 7'are also provided on the guide support shafts 6', 6 ', so that uniform printing pressure can be obtained over the entire area of the elongated stamp surface 3.

The stamp face 3 is kept in a state of protruding from the opening end 1a by the support springs 7, 7 ', 7'and is pushed in at the time of imprinting, and this stroke S is made by the support springs 7, 7', 7 '. It can be adjusted by operating the nut of the backup spring force adjustment mechanism.

The side plates 5 are provided along both sides of the print body 4 so as to be able to project and retract from the opening 1, and are used as a scale for aligning the stamp surface 3 with a printing position, for example. The illustrated side plate 5 is formed in a substantially gate shape in which a pair of left and right sides are integrated by the upper coupling portions 17, 17. The connecting portions 17 and 17 are locked to the upper surface of the holder 10 and are biased in the protruding direction by the auxiliary support springs 7'and 7'so that they project from the stamp surface 3 when not pressed.

The side plate 5 may be linear as shown in FIG. 1, but as shown in FIG. 2 or FIG. 6 (a), an arc-shaped tip edge 5a having a protruding center is provided and the center in the width direction thereof is provided. A mark 5d can be provided on the.

Further, the widthwise central portion 5c of the side plate 5 is left, and the cutout portion 5d is formed by cutting the side plate 5 in the vertical direction with a required width, and the printing operation of the internal print body 4 can be seen through the cutout portion 5d. It can also be configured as shown in FIG. 6 (b). The marks 5b and 5c can be provided on one or both of the upper side and the lower side of the printing surface 3 so that upper and lower judgment can be performed.

In each drawing, 18 is a lower member of the holding body 10, and 19 is a locking portion at the lower end thereof, which locks the printing body 4. Reference numeral 20 denotes a cap for opening and closing the upper side surface of the main body 2, which is attached and detached for replenishing ink.

In the stamping device configured as described above, when the portion of the stamp surface 3 is brought into contact with the stamping surface P when not stamped, the side plate 5 first comes into contact with the stamping surface P (FIG. 5A) and further pushes. Since the side plates 5, 5 retreat against the support springs 7, 7 ', 7', the marking surface 3 contacts the pressing surface (Fig. 5 (b)), and the end 1a of the opening 1 contacts the pressing surface P. And then stop (Fig. 5 (c)).

Although the stamp surface 3 is retracted by a predetermined stroke S by the pushing operation, the spring force adjusting mechanism for backing up the holding body 10 is adjusted by operating the nuts 14 and 15, so that the support springs 7 and 7 ′ are adjusted. It is possible to adjust the total spring force of 7'and 7'to obtain a constant printing pressure.

[0021]

[Effect of device]

 Therefore, according to the present invention, no matter how the printing operation is performed by anyone, only the printing surface pattern is printed, unnecessary portions such as the blank 3b are not printed, and the printing is printed with a constant printing pressure. Is remarkably sharp, and the quality is so high that it is comparable to the sharpness of printing. Therefore, it has a remarkable effect such as 100% reliability in computer reading accuracy.

Further, since the printing force can be adjusted by the spring force adjusting mechanism, even if the thickness or the character depth of the print body 4 is changed, it is possible to always obtain an appropriate printing pressure. Therefore, the manufacturing process control is minimal and the process itself is simplified. Further, in the conventional penetration type rubber stamp, the structure of the side plate 5 has forced the user to have an unnatural posture in order to determine the imprinting position, but the side plate in the present invention makes it easy to confirm the position, so that it is in a comfortable posture. , Can be pressed more accurately.
