Description

[Detailed Description of the Invention] The present invention relates to a device for printing numbers on slips, etc.
In particular, it relates to a serial number printer with check digits.

When operating an information processing system, it is necessary to minimize errors in input data in order to make the system accurate and reliable.

Recently, the amount of information processed by computers has increased significantly, and once erroneous data is entered into a computer, it is difficult to detect the erroneous data, and even if errors are discovered, It is extremely difficult to correct all newly generated data based on the error data, including that data.

Therefore, it is important that errors in information handling systems be detected and corrected before the data is entered into a computer.

In general, errors occur when creating a source document and when converting data from a source document to computer input media such as punch cards, paper tapes, etc., and both are largely due to human factors.

Therefore, it is necessary to create a data entry system that eliminates human factors. For example, by converting the original slip into a copy slip format, a slip that will be needed in the future can be created in one slip, and by reducing the number of slips, the number of errors can be reduced.

In addition, the entries are displayed in a systemized code, and the fixed code is mechanically printed in advance on the original slip, thereby reducing the number of entries to be entered manually and reducing the occurrence of errors. Furthermore, by processing the original slip using a heading number, business operations can be simplified and errors can be prevented from spreading.

By using such original documents, errors can be prevented to a certain extent, but by adding a check digit to the code or number mentioned above, errors can be prevented when reading, converting, or inputting data. can be automatically detected and corrected, and can prevent erroneous data from entering the computer processing system.

In view of the above-mentioned points, the present invention provides a new means effective for preventing the occurrence of errors in input data, and in particular, a method for printing a code or number with a check digit on an original document such as a copy document in advance. This invention provides a new number printing device with a check digit.

Conventional number printing devices for printing consecutive numbers on slips, etc. had only one digit for the check digit. Therefore, error detection using check digits was not perfect.

The number printing device of the present invention has the feature of being able to print not only one digit but also two or more check digits using two swings and two feed claws to enable more complete detection of errors. It has the feature of being able to print check digits with arbitrary missing numbers.

That is, the serial number printing wheel and the check digit printing wheel are rotatably supported on the same axis, and the feed pawl that drives the serial number printing wheel is mounted on the first swing or on the opposite side. Feed pawls for driving the check digit printing wheel are provided in the first swing and the second swing, respectively, and the first swing and the second swing are shifted in phase by their respective cam actions. The backward motion engages the feed pawl of the first swing on the serial number printing wheel on its attached ratchet, and the check digit printing wheel on its separate ratchet attached thereto. By configuring the other feed pawl of the first swing and the feed pawl of the second swing to be engaged and driven separately, the check digits can be made into one or two digits or more, and the number is printed. Although the device is purely mechanical, it is characterized in that it is possible to obtain a printing device that can print check digits with a high error prevention effect.

The construction of the wheel and ratchet shown in FIG. 2 allows the serial numbers and check digits to be printed at equal intervals and in a minimum amount of space.
Of course, if the spacing between the numbers can be wider, the latch may be placed in a different position without departing from the spirit of the invention.

The number printing device of the present invention drives character wheels 70 and 71 for printing check digits by engaging two feed pawls 72 and 74 and two ratchets provided on each character wheel, and also for printing consecutive numbers. The letter wheels are driven by meshing one feed pawl 66 with a ratchet provided on each letter wheel.

In the embodiment of the present invention, all the letter wheels are mechanically driven, but it is easy to incorporate a letter wheel for printing a fixed number into the printing device, and this would deviate from the purpose of the present invention. isn't it.

FIG. 3 is a plan view showing the arrangement of characters in each character wheel of the number printing device of the present invention, the shape of the ratchet, and the relationship with the feed pawl.

Conventionally, when printing a slip continuously, it is often done using multiple number printing devices.For example, when printing consecutive numbers using two printing devices, one printing device prints an even number. , the other printing device prints consecutive titles by alternately printing the odd numbers, one after the other. Similarly, when three printing devices are used, consecutive numbers can be printed by each printing device alternately printing the third consecutive number.

In the embodiment of the present invention, an example will be shown in which three number printing devices are used to print at third intervals.

In Fig. 3, the number 1 character wheel for printing consecutive numbers and the number 1 character wheel for printing check digits have the arrangement of numeric characters 0, 3, 6, 9, 2, 5, 8, 1, etc.
4, 7, and the 10th place and above are 0, 1,
The array is 2, 3, 4, 5, 6, 7, 8, 9.

When the number 1 character wheel is arranged as shown in Figure 3, by moving the character wheel one step at a time, for example 00
Numbers starting with 00, 03, 06, 09, 12, 15, 18,
21, 24, 27, 30... and you will get the third consecutive number. Similarly, numbers starting with 01 are 01, 04, 07, 10,
13, 16, 19, 22, 25, 28, 31..., numbers starting with 02 are 02, 05, 08, 11, 14, 17, 20, 23, 26, 29,
32..., each number is obtained in 3rd increments, and by matching the three types of numbers one after another, a series of consecutive numbers is obtained.

A ratchet shown in FIG. 3 is provided on the side of each character wheel, and engages with each feed pawl to advance the character wheel one step at a time.

As mentioned above, the feed pawl 66 for printing consecutive numbers becomes shorter as the higher digits are located, and normally the feed pawl 66 is 1
Only the claw of the place digit and the ratchet are engaged.

Further, the pawl of the feed pawl engages with the ratchet at a position one step ahead of the character position on the character wheel. For example, when the printed character is 9, the pawl of the feed pawl is advanced one step by engaging with the ratchet of the next character to be printed.

When the 1st place character ring rotates one step at a time and the feed pawl engages with the deep groove of the ratchet, the 10th place digit pawl and the 10th place digit ratchet engage, and both the 10th place and 1st place character wheels rotate one step. It is advanced and a carry is performed.

Furthermore, when the 10th and 1st position claws are both engaged with the deep grooves of the ratchets of each girder, the 100th position, 10th position,
The first-placed characters move forward one step together.

In this way, by combining the length of the feed pawl and the deep groove of the ratchet, it is possible to carry up a character ring of multiple digits.

The position of the deep groove of the ratchet is 7 on the 1st digit wheel.
→ 0, 8 → 1, 9 → 2 are provided in three locations, and for characters in the 10th digit or higher, they are provided in one location that progresses from 9 to 0. The ratchet shown in FIG. 3 mechanically obtains the third consecutive number.

Further, as shown in FIG. 3, the number printing device of the present invention is provided with a two-digit check digit ring.
Each of the 10th and 1st place wheels has two ratchets of different shapes.

Furthermore, two feed pawls 72 and 74 are provided for driving the character wheel for printing the two-digit check digit.

The feed pawl 72 advances the check digit number in 3rd increments, and its operation is based on consecutive numbers.
Same as 10th and 1st place.

The feed claw 74 has check digit numbers 97 and 98.
Or, when it reaches 99, it engages the deep groove of the ratchet of each digit, and both the 10th and 1st character rings become 1.
Step forward and send to 97→00, 98→01, or 99→02.

If the check digit number is from 00 to 89,
The 10th position pawl, which is longer than the 1st position of the feed pawl 74, is located at the level of the flat part A on the top surface of the 10th position ratchet, and
Due to the short length of the nails, they do not engage with the ratchet and cannot push the wheel forward.

When the check digit number reaches the 90s, the 10th position pawl of the feed pawl 74 enters the deep groove of the ratchet. At this time, the first digit of the check digit number is 0-3.
-6, 2-5, 1-4, the 1st position pawl is at the height of the 1st position rachiet, and the 10th position pawl is at the height of the middle part 4 of the deep groove of the 10th position ratchet. , both cannot push the wheel forward. In other words, when the check digit number is between 90 and 96, the feed pawl 74 does not advance the character wheel.

Further, when the first check digit becomes 9, 8, or 7, the first pawl of the feed pawl 74 enters the three deep grooves provided in the first ratchet, and at the same time, the tenth pawl enters the three deep grooves of the tenth ratchet. Enter the deep groove at position C, and use the feed pawl 74 to move the two
Push the step forward.

As explained in detail above, the two character wheels for printing check digits in the number printing device of the present invention are driven by the feed pawl 72 when the check digit number is between 00 and 96, and the two character wheels for printing check digits Feed claw 7 only when becomes 97, 98, 99.
4, advance to 97→00, 98→01, 99→02.

FIG. 4 shows the shape of the cam groove for driving the number printing device of the present invention shown in FIGS. 1, 2, and 3.
(The arrangement of the number printing device and the cam is shown in FIG. 7.) The rollers 21 and 31 supported on the tips of the arms 20 and 30 explained in FIGS. 1 and 2 are connected to the two rollers 21 and 31 shown in FIG. Cam 25 and cam 3
It meshes with 5.

The radial lengths of both cams 25 and 35 from the center 0 are not constant and are eccentric. This eccentric cam causes the arms 20 and 30 of the number printer to rotate back and forth. Moreover, since the cams 25 and 35 have different eccentric positions, the arms 20 and 3
0 and rotates backwards with a phase difference.

In other words, when the number printing device rotates around 0,
First, the eccentricity of the cam 35 causes the swing 50 connected to the arm 30 to move backward, and the feed pawl 72 supported on the swing 50 advances the check digit printing character wheel one step.

Next, the eccentricity of the cam 25 causes the swing 40 connected to the arm 20 to move backward, and the feed pawl 66 supported on the swing 40 pushes the serial number printing letter wheel one step forward.

Furthermore, if the feed pawl 74 supported by the swing 40 is engaged with the groove of the ratchet provided in the check digit printing wheel, the check digit printing wheel is moved to 1 again at the same time as the serial number printing wheel.
You will have to take a step forward.

That is, normally, the check digit wheel is advanced by the cam 35, and then the link number wheel is pushed forward by the cam 25, so that 1
The first operation is completed, but when the number of the check digit wheel pushed one step forward by the cam 35 is 97, 98 or 99, the cam 2 is pressed again.
5 advances the check digit wheel one step to 00, 01 or 02.

In this manner, the number printing device of the present invention repeatedly prints the numbers 00 to 96 without printing the check digits 97, 98, and 99.

In the embodiment of the present invention, a ring cam is used to forcibly move the arm back, but an open cam can be used when returning to swing and incorporating a spring. It is also obvious that a stationary or plunger type number printing device can be constructed by driving the cam without rotating the number printing device, and the gist of the present invention does not change in this case.

FIG. 5 is a sectional view showing the structure of the 10th and 1st digits of the check digit.

A wheel shaft 8 is installed between both ends of the frame 10.
0 and the pole shaft 81 are fixed. Rings 70 and 71 having ratchets are rotatably fitted into the outer periphery of the wheel shaft 80, and an arm shaft 33 is rotatably fitted into the inner periphery of the wheel shaft 80, and an arm shaft 23 is rotatably fitted into the inner periphery thereof.

The character rings 70 and 71 each have 10 of 0 to 9 on the outer peripheral surface.
The letters are spaced at equal intervals (36 degrees), and the sides of the letter wheel are provided with ratchets with two different shapes. A feed pawl 72 and a feed pawl 74 engage with this ratchet to push the character wheel one step at a time.
is provided on the outer periphery of the character ring, and the feed pawl reciprocates around the axis 0 and operates at an angle of at least 36 degrees.

Considering the durability of the number printing device, wear and tear of parts, etc., it is best to allow some leeway in the operating angle and set it at around 45 degrees.

Pole shafts 81 are movably fitted with pawls 82 and 83 having protrusions at their tips for each ring, and the protrusions engage with grooves of a ratchet provided at 36° intervals.

The pawls 82 and 83 are pressed against the ratchet by springs 84 and 85 embedded in the frame 10, respectively. In this way, the pawls 82 and 83 supported by the springs can define the stopping position of the character wheel by engaging with the grooves of the ratchet, and eliminate unnecessary vibrations transmitted through the feed pawls 72 and 74. Absorb influence.

Of course, although not shown in FIG. 5, each of the serial number rings is also provided with a pole.

The 10th place feed pawl 74 and the 1st place feed pawl 74 are integrated, and the 10th place feed pawl 72 and the 1st place feed pawl 72 are also integrated.

FIG. 6 shows a condition in which the first digit character wheel 71 for printing a check digit is advanced two steps during one revolution of the number printing device. Of course, it is clear that in this case the 10 digit wheel 70 is moved one step from 9 to 0.

In FIG. 6, the number printing device prints 96 at the printing point a, and while it rotates once around the axis 0, the number printing machine prints 96 from 6 to 9 between b and d using the feed pawl 72. It is pushed one step forward, and further, between e and g, it is pushed one step forward from 9 to 2 by the feed pawl 74, and at the same time, the 10th position wheel 70 is also pushed one step forward from 9 to 0. Thereafter, ink is supplied to the type surface by the inking roller, and printing is performed again at position a.

FIG. 7 shows a state in which the number printing device of the present invention is incorporated into a part of a unit of a slip printing machine.

The slip 1 is sent from a preceding unit (not shown), such as a printing unit or a collating unit that collates multiple sheets of slip paper, and is successively numbered in the number printing unit shown in FIG. It is sent to a subsequent unit, for example a folding device or a cutting device.

The number printing units 91, 92, and 93 are each fixed to a mount 94 with an interval of 120 degrees, and the mount 94 is further fixed to a shaft 95 and rotates in synchronization with the other units. Further, each number printing device rotatably supports type wheels 96, 97, 98, and arms 104, 105, 1 for driving the type wheels.
06 is provided to protrude from the number printing device, and the roller at the tip thereof is arranged to slide within the cam groove of the cam 25.

Furthermore, the inking roller unit 10 is arranged so as to be in contact with the rotating outer circumferential circle of the type wheel of the number printing device.
7, 108, and 109 are arranged, and an impression cylinder 100 is provided at a location in contact with the slip.

In FIG. 7, as the slip 1 progresses, numbers with check digits are printed at predetermined intervals by the letters on the wheel of the number printing device.

The tip of the arm fitted with the cam is connected to the shaft 9.
As the number 5 rotates, the character wheel moves backward one step at a time.

In FIG. 7, the other cam 35 and the arm 10
1, 102, and 103 are partially omitted.

When printing consecutive numbers using three number printing devices, it is sufficient to set the character ring of each printing device to be a different number in advance. This is easily done by pushing each ring individually one step at a time with your finger.

In FIG. 7, when the slip 1 is a single sheet of paper, a number is printed on the surface of the paper by a letter wheel supplied with ink by an inking roller unit.

In addition, when the slip 1 is made up of multiple sheets of paper, the number can be printed on the lower paper by composing the slip with paper coated with carbon ink or non-carbon ink in advance, so that the front paper can be printed with carbon ink or non-carbon ink. Numbers can be printed using the ink supplied to the letter wheel, and the paper at the bottom can be printed with carbon ink or non-carbon ink.

Various changes can be made to the structure of the number printing device of the present invention described above.

(1) Continuously numbered feed pawls may be provided on either of the two swings.

(2) The phase of the feed claw of the check digit may be reversed. However, the shape of the ratchet that engages with the feed pawl 74 has been changed, so that the ratchet for the 10th digit is not necessary, and the deep groove of the ratchet for the 1st digit is 4.
→7, 6→9, 5→8.

(3) The check digit number can be not only 00 to 96 but also 01 to 97, 02 to 98, or 03 to 99.

(4) Furthermore, it can be easily inferred from the gist of the present invention that certain numbers from 00 to 99 can be made unprintable.

(5) Furthermore, it is easy to infer that not only 2-digit numbers but also 3-digit or more specific numbers can be made unprintable.

(6) In addition, enter the 10 digits as 012345, 012345 or
If the number is repeated twice or more, such as 1234, 1234, 1234 or 012, 012, 012, all kinds of specific numbers can be printed, and specific numbers can also be made unprintable.

As explained in detail above, the present invention rotatably supports a serial number printing wheel and a check digit printing wheel on the same axis, and a feed pawl that drives the serial number printing wheel.
