Description

[Detailed explanation of the invention] This invention aims to save labor in so-called counter operations in various government offices, etc.
Authentication using an automatic authentication machine that prints and feeds paper at the same time by arranging certified versions of family registers and other certified copies around the certification text block in the printing drum, and selecting and using these certified versions as necessary. The present invention relates to an authentication text switching device that can select a required authentication version by rotating the text block, and is further provided with a fixed position stopper mechanism that suppresses and fixes the authentication text block during printing.

In recent years, the printing drum has been equipped with a certification text block with multiple certification plates that can be selected as appropriate, and the certification text block of automatic certification machines that perform printing and paper feeding at the same time has been used in order to print with appropriate density, or In order to change the size of the block itself, it became necessary to move it.

However, since the authentication text block must be rotatable in order to select the authentication version, and the rotation must be maintained during printing, it has conventionally been impossible to move the authentication text block.

In particular, this invention enables printing of appropriate density by freely rotating and holding the authentication block to select the authentication plate even when the authentication block is moved, and the size of the authentication text block can be changed as necessary. The purpose is to make it easier to use by ensuring that the parts are the same even if the size is changed. In an automatic authentication machine having a printing drum which pivotally supports a certification text block with a plurality of certification plates fixed to the periphery between these drum sides, a switching drive having the same axis as the rotating shaft is used. A driving gear is fixed to the shaft, a driven gear is fixed to the block shaft provided at the center of the axis of the certification block, and an intermediate gear is provided from each of the switching drive shaft and the block shaft to mesh with these gears and transmit rotation. The block shaft is rotatably supported by a link, and the block shaft is further provided with a fixed position stopper mechanism for suppressing rotation of the block shaft.

An embodiment of the present invention will be described below with reference to the illustrated example.

That is, in order to perform printing and paper feeding at the same time, the printing drum has an authentication text block 30 that is provided on the printing drum 10 that is rotated by a printing drum rotation mechanism and that can move forward and backward in the radial direction of the rotation shaft 12 of the printing drum 10. 10
A case will be described in which an authentication text switching mechanism 50 is provided as a rotation switching device, and a fixed position stopper mechanism 90 is provided as a rotation stopping device.

The printing drum 10 is constructed by disposing a connecting rod 15 between two drum sides 14 each having a knurled portion 13 at a proper position on the outer periphery to maintain a constant spacing, and a rotating shaft 12 provided approximately in the center of the two drum sides 14 to maintain a constant spacing. A printing plate fixing portion 16 is provided at the top.

The rotating shaft 12 is provided to protrude outward from one drum side 14, and a print drum rotation mechanism 70 for transmitting external power to the print drum 10 by a pulley 71 or the like is provided on the protrusion from the drum side 14. It is.

On the other drum side 14, a switching drive shaft 51 for rotating the authentication text block 30 from the outside is provided with the same axis as the rotation shaft 12, and the switching drive shaft 51 is located inside the printing drum 10. The end is rotatably fitted into a support hole 17 formed in the axis of the rotating shaft 12.

A switching dial 52 is provided at the tip of the switching drive shaft 51 protruding from the printing drum 10.
An appropriate number of switch cams 53 are provided on the switching drive shaft 51 between the and drum side 14 to detect the position of the authentication plate 31 to be printed among the various authentication plates 31 provided in the authentication text block 30. Furthermore, a microswitch 54 for detecting the position of the switch cam 53 is provided near the switching drive shaft 51.

The authentication text block 30 is fixed to a block shaft 32, and both ends of the block shaft 32 are fitted into the radially long movable elongated holes 18 of the rotating shafts 12 provided on the two drum sides 14.

Further, the authentication text block 30 is formed so that a plurality of authentication plates 31 can be fixed around it.

Furthermore, the driving gear 55 is connected to the block shaft 3 on the switching drive shaft 51.
A driven gear 56 is fixed to each of the switching drive shafts 5 and 2.
An intermediate gear 59 that meshes with the two gears 55 and 56 is pivotally supported by links 57 and 58 provided between the block shaft 32 and the block shaft 32, thereby forming an authentication statement switching mechanism 50.

In addition, 60 and 61 in the figure are links 57, 58 and intermediate gear 5.
These are bolts and nuts for supporting the 9.

Further, both ends of the block shaft 32 are connected to the drum side 14 of the printing drum 10 through the movable elongated hole 18 bored in the drum side 14.
Approximately the same authentication text block advancing/retracting devices 80 are provided in the protruding portions on both sides.

One of the authentication text block advancement/retraction devices 80 includes an adjuster 81, an eccentric wheel 82 for vertically moving the adjuster 81, and a handle wheel 83 for rotating the eccentric wheel 82.
It is empty.

The adjuster 81 has a flat plate shape and is provided facing the outer surface of the drum side 14, and a central elongated hole 84 which is long in the radial direction of the rotating shaft 12 and into which the rotating shaft 12 is fitted approximately in the center corresponds to the position of the block shaft 32. Adjustment is made such that the pivot hole 85 is located on the opposite side of the pivot hole 85 on a line connecting the pivot hole 85 and the central elongated hole 84 and is long in a direction perpendicular to the line, and accommodates the eccentric ring 82 internally. Elongated holes 86 are provided in each case.

The adjuster 81 is installed by fitting or supporting the center elongated hole 84 and the pivot hole 85 on the rotating shaft 12 and the block shaft 32, fixing the eccentric wheel 82 to the handle wheel 83, and inserting the eccentric ring 82 into the adjustment elongated hole 86. This is done by internally storing it and fixing it to the drum side 14 with a fixing screw 87.

Although the drawing shows only the authentication text block advance/retract device 80 on one side, two such devices 80 are provided on both sides of the drum side 14.

Further, the adjuster 81 is provided with a fixed position stopper mechanism 90 that suppresses the rotation of the authentication text block 30, which is rotated by the rotation of the switching drive shaft 51, at a fixed position.

This fixed position stopper mechanism 90 has a positioning cam 92 fixed to the end of the block shaft 32 and having a cam groove 91 recessed around the periphery equal to the number of authentication plates 31 provided in the authentication text block 30, and further fixed to the adjuster 81. A positioning ball 9 is constantly pressed by a coil spring 94 whose elastic force is adjusted by an adjustment screw 93 so that it fits into a groove 91.
A holder 96 from which the holder 5 protrudes is fixed to give an appearance.

Therefore, if the authentication text block 30 is rotated with a strong force, it will rotate, but the authentication text block 30 will not rotate or shift during the printing operation.

Note that this fixed position stopper mechanism 90 is connected to the block shaft 32.
Although it is sufficient to provide it on at least one of the shaft ends, reliability is improved if it is provided on both sides.

Next, the operation and operation of the printing section in the automatic authentication machine will be explained.

First, the fixed printing plate 11 is fixed to the printing plate fixing portion 16 of the printing drum 10 with the printing surface aligned with the outer periphery of the printing drum 10.

This fixed printing plate 11 is always a fixed printing plate even if the type of authentication plate 31 is different, such as the name of the registrar or the name of the legal affairs bureau.

Next, on the outer periphery of the certification text block 30, various certification plates 31 indicating that the certificate is a certified copy of, for example, a real estate registry, a corporate registry, a family register, etc., are fixed.

Here, the authentication text block 30 is used by appropriately selecting a square prism, a hexagonal prism, etc., depending on the required number of authentication plates 31 (= matching).

Next, the authentication text block advancing/retracting device 80 is activated to move the authentication version 3 fixed to the surface of the appropriately selected authentication text block 30.
The printed surface of No. 1 is made to match the printed surface of fixed printing plate 11.

That is, the handle wheel 83 is rotated by the same angle on both sides of the drum side 14, and the eccentric wheel 82 is adjusted accordingly.
The adjuster 81 is moved back and forth in the radial direction of the rotating shaft 12 by the eccentric length of the eccentric ring 82.

Then, as the adjuster 81 moves back and forth, the block shaft 32 supported by the pivot hole 85 of the adjuster 81 moves back and forth, and the authentication text block 30 fixed to the block shaft 32 simultaneously moves back and forth in the radial direction of the rotary shaft 12. .

By moving the authentication text block 30 back and forth, the printing surface of the authentication plate 31 is made to match the outer periphery of the printing drum 10, and when the authentication plate 31 is printed, the printing is adjusted so that it is not too light or too dark.

After this adjustment is completed, the handle wheel 83 and the eccentric wheel 82
are integrally fixed to the drum side 14 with a fixing screw 87, so that the adjuster 81 cannot move forward or backward.

In the illustrated example, the handle wheel 83 and the eccentric wheel 82 are shown as separate bodies, but they may be integrally formed.

Also, when the adjuster 81 moves back and forth, the rotation shaft 12 is connected to the block shaft 3 through the central elongated hole 84 of the adjuster 81.
As for 2, they can escape through the long movement holes 18 of the drum side 14, and the adjuster 81 will not collide with the rotating shaft 12 or the block shaft 32.

Furthermore, when the adjuster 81 moves back and forth, the distance between the switching drive shaft 51 and the block shaft 32, that is, the distance between the driving gear 55 and the driven gear 56, differs.

However, between these, the intermediate gear 59 whose fulcrum is not fixed is connected to the drive gear 55 and the intermediate gear 5 by the links 57 and 58 provided between the switching drive shaft 51 and the block shaft 32.
Since the distance between the axes of each of the intermediate gear 59 and the driven gear 56 is constant, rotation of the driving gear 55 is always transmitted to the driven gear 56 via the intermediate gear 59.

Further, even if the adjuster 81 moves, the fixed position stopper mechanism 90 stops the positioning cam 92 and the holder 9 accordingly.
6 moves at the same time, so not only does the stopper function not be impaired in any way, but also the adjuster 81 moves in the radial direction of the rotating shaft 12, and along with this, the adjuster 81
Since the block shaft 32, the authentication text block 30, and the fixed position stopper mechanism 90 provided in the authentication text block 30 also move in the radial direction of the rotating shaft 12,
always moves perpendicularly to the outer periphery of the printing drum 10 and is fixed at right angles by the fixed position stopper mechanism 90, so that the authentication plate 31 is not tilted and accurate printing can always be performed.

Furthermore, when this fixed position stopper mechanism 90 is provided on the switching drive shaft 51, play occurs in the block shaft 32 by the amount of backlash of each gear 55, 56, 59 between it and the block shaft 32 whose rotation is to be stopped, resulting in printing failure. Not only is there a possibility that the switching drive shaft 51 is fixed and the block shaft 32 is moved, but the intermediate gear 59 is moved around the drive gear 55 by the amount that the inclinations of both links 57 and 58 are changed. moves while rotating, and the rotation of the intermediate gear 59 causes the driven gear 56 to rotate, and the authentication text block 30 that is linked to the driven gear 56 tilts, making it impossible to print. However, in the present invention, the authentication text block 30 is fixed. Since the fixed position stopper mechanism 90 is provided directly on the block shaft 32 to stop its rotation, the above-mentioned drawbacks cannot occur.

Furthermore, an authentication statement switching mechanism 50 and a fixed position stopper mechanism 9
0 can be formed using the same parts even if the block shaft 32 is moved or fixed or the size of the authentication text block 30 is changed, and can be formed at low cost.

Next, after preparing for printing by rotating the switching dial 52 to select a predetermined authentication version 31, the printing drum rotation mechanism 7
0 to print on a predetermined paper 100.

Since the printing drum 10 rotates during this printing, the paper 100 is fed out by the knurling portion 13 of the printing drum 10 at the same time as printing is performed.

Also, the authentication version 3 selected by rotating the switching dial 52
If type 1 is detected by a switch cam 53 and a microswitch 54 provided on the switching drive shaft 51 and displayed externally (not shown), mistakes in selection of the authentication version 31 will be eliminated and the operation will be reliable. will improve.

Note that since the switching drive shaft 51 has the same axis as the rotating shaft 12, even when the printing drum 10 rotates, it only rotates around the axis and does not interfere with the printing operation.

As described above, in this invention, the authentication text block rotates accurately by the rotation of the switching drive shaft, and the rotation of the block axis is suppressed depending on the position of the authentication plate, so that constant and reliable printing can be performed at all times. In addition, printing errors due to blurring of the authentication plate do not occur, and this has extremely practical effects.
