Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stamp height adjusting type stamping device.

[0002]

[Prior art]

 Rubber stamps, which supply ink in a penetrating manner to a stamp surface composed of letters, numbers, symbols, etc., are well known and are well-received because a clear impression can be obtained. However, the printing pressure, that is, the pressing force, differs every time the pressing is performed, and the pressure cannot be controlled. Therefore, there is a problem that a clear imprint cannot always be obtained. In particular, if there is a space between the prints, if it is pressed too hard, the space portion may come into contact with the printing surface, which is a drawback.

Further, the conventional ink permeation type rubber stamp has a constant printing pressure. In other words, the pressure is set to the optimum pressure when manufacturing the infiltration type rubber stamp, but it is necessary to control the character height (character depth) and the total thickness very strictly, which requires a lot of time and time. The expenses have been spoiled.

When the imprint changes depending on the printing method, that is, the printing pressure, an excessive amount of the printing pressure supplies a proper amount of ink several times to the printing surface, causing “bleeding” due to excess ink. Blur the imprint. 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 in view of the above points, and its problem is to make it possible to configure a mechanism capable of adjusting the height of the stamp face with a minimum number of parts so as to obtain an optimum impression result. Especially.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention has a shaft body 4 having a marking surface 1 at the lower end and having a male thread 3 on an upper portion of a printing body 2 and having a female thread 5 which can be screwed onto the male thread 3. An adjusting member 6 for adjusting the amount of protrusion of the stamp surface 1 forward and backward according to the degree of screwing is screwed onto the male screw 3 of the shaft body 4, and a printing body is provided between the adjusting member 6 and the printing body 2. A casing 7 having a size that surrounds 2 and having a lower end opened is provided, and a support portion 18 that slidably inserts the shaft body 4 of the printing body 2 is provided in the partition wall 17 inside the casing 7. , The adjusting member 6 and the casing 7 are slidably connected to each other, and the print body 2 is pressed, the spring 8 is attached to the adjusting member 6 and the support portion 18, and the holder 10 for pushing operation is attached. A means for removably attaching the adjusting member 6 to the part 9 is provided. Than it is.

【Example】

 A description will be given below with reference to the drawings. The embodiment is an example in which the present invention is applied to a penetration type rubber stamp.

A stamp surface 1 formed by a combination of printing and the like is formed on the lower surface of the printing body 2, and a stamp image is formed by a printing operation. The printing body 2 is for a permeation type rubber stamp in which an ink reservoir 11 capable of impregnating ink is integrally provided on the back of a member provided with the printing surface 1, and the ink is printed through a rubber material having open cells. It has a structure that is supplied up to.

The printing body 2 is integrally assembled to a lower end of a holding body 13 having a replenishing hole 12 for replenishing the ink reservoir 11 with ink, and the casing 7 is vertically movable together with the holding body 13. Incorporated into. That is, the holding body 13 has a central main support shaft 14 and left and right guide support shafts 15 and 15 '. The main support shaft 14 is fitted in a support portion 18 formed in a cylindrical shape on the partition wall 17 of the casing 7 and is vertically movable, and the guide support shafts 15 and 15 ′ are formed on the left and right sides of the support portion 18. It is similarly inserted into the holes 19 and 19 'to prevent the stamp face 1 from swinging.

The casing 7 is formed in a tubular shape having a size and shape that surrounds the print body 2, and is divided into upper and lower parts by a partition wall 17 provided near the middle. The holder 3 incorporated in the casing 7 can be moved downward by a stroke in which the printing surface 1 of the printing body 2 can project from the open end 16.

The main support shaft 14 is provided with a shaft body 4 having a male screw 3 on the upper side, and the shaft body 4 moves up and down together with the printing body 2. A adjusting member 6 having an internal thread 5 is screwed onto the external thread 3. The adjusting member 6 has a flange 20 at its lower end, and the flange 20 also serves as a spring receiver, and connects the upper end of a spring 8 interposed between the printing body 2 and the adjusting member 6. Therefore, when the adjusting member 6 is operated, the compression length of the spring 8 changes, and the shaft body 4 having the male screw 3 connecting the lower end of the spring 8 moves relatively in the axial direction. FIG. 2 shows a state in which the printing body 2 supported by the shaft body 4 is at the highest position. When the shaft body 4 is lowered, the distance between the stamp face 1 and the opening end portion 16, that is, the height h of the stamp face 1 changes. .

The mounting portion 9 is provided downward at the center of the holder 10 for the pushing operation, and is fitted and fitted in the fitting port 21 whose lower end is open. The holder 10 has a lower end housed in the upper opening of the casing 7 and is assembled so as to be vertically slidable. The holder 10 is formed in a box shape with the upper end closed, and also serves as a member for a pushing operation.

In the printing apparatus having such a structure, when the stamp surface 1 is brought into contact with the stamp surface, the opening end 16 of the casing 7 first comes into contact with the stamp surface, and when the stamp is further pressed, the printing body 2 is springed. Since it descends against 8, the stamp surface 1 comes into contact with the stamping surface and stamping is performed. The stamp surface 1 moves by a predetermined stroke during the imprinting operation, but when the holder 10 is removed, the adjusting member 6 screwed with the male screw 3 of the shaft body 4 planted in the printing body 2 is rotated. The height h of the stamp surface 1 can be adjusted with the state of FIG. 2 as the highest position. That is, when the adjusting member 6 is operated and the shaft body 4 is projected downward, the holding body 13 is separated from the partition wall 17 and the height h of the stamp face 1 is reduced.

[0014]

[Effect of device]

 Therefore, according to the present invention, the height from the opening end 16 at the lower end of the casing 7 in which the print body 2 is housed to the stamp surface 1 can be adjusted by operating the adjusting member 6, so that the marking can be performed. It is easy to obtain a printing device having a uniform stroke on the printing surface. If the printing device is used, the printing device 2, the shaft member 4 provided on the printing member 2, the adjusting member 6 for operating the shaft member 4, and the casing incorporating them are provided. Since it is composed of 7 and the spring 8, it is suitable for mass production and can be expected to have high practicality.
