Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a numbering device with check digits, and particularly to a numbering device with check digits that simultaneously prints a code number to be printed and a check digit corresponding to the code number.

Generally, a check digit is a one-digit number calculated from the numerical value of a code number, and is added, for example, after the last digit of the code number, to detect errors in coding or the like.

That is, important key numbers, such as account numbers and customer code numbers, are added to prevent errors such as account mistakes.

Conventionally, the method of calculating this check digit is as follows:
Examples include a Luhn's check, a Modulus 10, a Modulus 11, a Nine's check, etc., which have various specified weights.

On the other hand, check digits do not necessarily change continuously for each successive code number, except for nines checks where specific numbers simply cycle.

For this reason, it has traditionally been technically difficult to obtain a numbering device with check digits that can simultaneously and continuously print out check digits for consecutive code numbers, especially due to the difficulty in selecting check digits. and was left unresolved.

Therefore, when calculating and printing check digits at the administrative stage, addition, subtraction, multiplication, and division are performed according to a predetermined calculation method based on the predetermined modulus and weight for each printed code number, and the check digits are calculated and annotated. The method was adopted.

However, this conventional method has the disadvantage that it takes a lot of time and effort to calculate and print the check digit.

In view of the above-mentioned matters, an object of the present invention is to provide a code number printed by a numbering device and a check digit corresponding to the code number, especially a check consisting of a single digit number that has a singularity even when there is a carry, such as in a runes check. To provide a numbering device with a check digit, which can simultaneously and continuously print out digits and digits by pressing a press rod.

The present invention provides a numbering device with check digits equipped with a check digit type wheel, in which a plurality of check digits are printed on the check digit type wheel, which are calculated and specified in advance based on the modulus and weight used. The check digit type wheel is arranged between the check digit type wheel and the feed pawl mechanism in synchronization with the intermittent rotation of the printing unit, and the rotation angle is at least twice that of the printing unit. This objective is achieved by, for example, installing a double-angle rotation synchronization mechanism that rotates intermittently at different angles.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

First, the properties of tick digit numbers that have made it possible to provide the numbering device with check digits according to the present invention will be explained using a runes check as an example.

Now, the code number CKI (however, = 0 to n: n is a natural number)
If you calculate the check digit for each of them using runes check, the result will be as shown in the following table.

Further analysis of this shows that for code number "0", the check digit is naturally "0",
Check digit is “8” for code number “1”
, the check digit is “6” for the code number “2”.
'', it has become clear that the check digit in runes checks has a certain regularity.

That is, the check digit for each code number starting with "0" is a cyclic number sequence [0, 9, 8° 7.6...
..., 2. In iJ, starting from the first number "0", one skipped number is calculated sequentially (for example, for code number "1", the check digit is "8", for code number "2", the check digit is "6",...
), when the last digit of the code number moves from "4" to "5", the next number is calculated by skipping two specific numbers in the recurring check digit sequence (for example, It has become clear that the check digit for code number "4" is "2", whereas when the code number becomes "5", the check digit becomes "9").

Furthermore, it has become clear that when carrying from the last two digits of the code number, ``99'', there is a singularity in which at least three or more numbers in the cyclic sequence are skipped to calculate the next number. Ta.

In other words, it has been found that the check digits for each code number starting from "10" have a certain regularity on the one hand, and at the same time always have a singularity in at least one place on the other hand.

For these reasons, when providing a numbering device with check digits, it is necessary to have a double-angle rotation synchronization mechanism to always rotate the check digit type wheel at least one time at a time, and In order to respond to changes in code numbers, a memory control mechanism that rotates the check digit type wheel at an arbitrary angle at the singular point, or a mechanism similar thereto is required.

Next, a specific example of a numbering device with a check digit according to the present invention that utilizes the properties of the check digit described above will be described.

C is formed to be shorter than the claw portion 10A by 3Δ.

Further, the claw portion 10D is formed to be shorter than the claw portion 10A by 5Δ, similarly, the claw portion 10E is shorter than the claw portion 10A by 6Δ, the claw portion 10F is shorter by 8Δ, and the claw portion 10G is shorter than the claw portion 10A by 9Δ. It is thus formed.

The shape of each of these claw portions 10A to 10G is formed substantially the same as a known one.

Each claw part 10A to IOG of the feed claw mechanism 10 is individually pressed by a spring or the like in correspondence to each claw tooth part 1A to 1G of each feed claw locking gear 1, 1, . . . of the printing unit 3. They are interlockingly engaged.

Each of the pawl teeth 1A to 1G is provided with a known deep groove for carrying (not shown) which functions when the type wheels 2, 2, . . .

For example, when the pawl 10A falls into this deep carry groove, the pawl 10B engages with the corresponding type wheel, and the pawls 10A, 10B
The type wheel 2.2 corresponding to the digit number is simultaneously rotated to advance one digit, and a claw 10A is installed in each carry groove.
.

10B fall at the same time, the third digit type wheel 2 is also locked to the pawl 10C and rotates, and as the digits are fed to the upper digit, the pole shaft fulcrum 9A of the entire feed pawl mechanism 10 is moved. The rotation angle is formed so that the rotation angle relative to the

In the printing unit 3, at the bottom of the pawl tooth portion 1A of the feed pawl locking gear 1 of the type wheel 2 that prints out the first digit [5I, there is a character wheel singularity for displaying a singularity whose depth is approximately equal to Δ. groove(
(not shown) is formed.

When the pawl 10A falls into the singularity groove of depth Δ, a predetermined rotation angle is output to the horizontal rod 8A.

On the other hand, the length of the other nails 10B, 10C... is the same as that of the nail 1.
Since it is shorter than 0A by 2Δ or more, the claw 10
Even if A falls into the singularity groove, the feed pawl locking gear 1

and a double angle rotation synchronization mechanism 1 for synchronizing the check digit type wheel 7 with the intermittent rotation of the printing unit 3.
1, and a synchronization release mechanism 12 for separating the double angle rotation synchronization mechanism 11 from the check digit type wheel as required.

The double angle rotation synchronization mechanism 11 includes a ratchet gear 13 fixed to one end of an indirect coupling shaft 20 with a check digit type wheel 7, which will be described later, and having 20 claw teeth, and a claw portion at one end of the ratchet gear 13. is interposed between the check digit type feed pole (hereinafter simply referred to as "CD pole") 14 and the CD pole 14 and the feed claw mechanism 10, and the reciprocating rotation of the feed claw mechanism 10 is provided. Spring 15 and CD that transmit power to CD pole 14
and a double angle gear mechanism 61 that doubles the rotation angle of the ratchet gear 13 and transmits it to the check digit type wheel 7.

To explain this in more detail, the central portion of the CD feed pole 14 is rotatably mounted perpendicular to the horizontal rod 8A.

One end of a tension spring 15 is hooked to the pawl side of the CD pole 14, and the other end is fixed to the feed pawl mechanism 10, and a CD ball extending toward the check digit type wheel 7 side. It is hooked to a stopper 16.

The double angle gear mechanism 61 has a gear ratio of 3/2 and a gear ratio of 4/2.
3, two sets of gear mechanisms are used.

As a result, when the feed pawl mechanism 10 rotates by a predetermined angle with respect to the pawl fulcrum 9A, the CD pawl 14 is urged by the tension spring 15 and pressed against the ratchet gear 13, so that it is integrated with the feed pawl mechanism 10. Said CD pole 1
4 rotates, each time the ratchet gear 13 is rotated by 1/1.
At the same time, the check digit type wheel 7 is rotated by 2/10 of a rotation via the double angle gear mechanism 61.

The synchronization release mechanism 12 operates when the feed pawl mechanism 10 falls into the carry deep grooves and other character wheel singularity grooves formed in the feed pawl locking gears 1, 1, . . . starting from the lowest digit. , a pinion 17 having a function of separating the double angle rotation synchronization mechanism 11 from the check digit type wheel 7, and whose center shaft is fixed to the horizontal rod 8A;
a small gear 18 meshed with the horizontal rod 8B and rotatably mounted on the horizontal rod 8B; It is composed of a control pin 19.

The amount of rotation of the feed pawl mechanism 10 differs depending on whether only the first character wheel 2 of the print wheel 3 is intermittently rotated or when it is locked in a deep groove during carry, for example.

Therefore, in this embodiment, in order to prevent the operation of the synchronization release mechanism 12 except in the case of a carry and in the case of a singularity, in the normal case, the control pin 19 and the CD
A certain distance is provided between the pole 14 and the pole 14 for use.

The check digit type wheel 7 is connected to an indirect coupling shaft (hereinafter simply referred to as "CD") with a drive source 21 that functions immediately after the disengagement operation of the synchronization release mechanism 12 and rotates the check digit type wheel 1. It is equipped via a vehicle-to-vehicle coupling shaft (20).

Both the CD vehicle coupling shaft 20 and the drive source 21 are rotatably mounted on the support shaft 5.

The drive source 21 may convert the amount of rotation of the feed pawl mechanism 10 into an amount of electricity, convert it into an A/D converter, and then drive it by a step motor or the like. The synchronization release mechanism 12 can be replaced with a simple electric circuit), but in this embodiment, it is configured as follows.

That is, one end portion of a driving torsion spring 22 is fixed to the left end portion of the CD wheel coupling shaft 20 in FIG. 1, and a cam wheel 23 is locked to the other end portion of this driving torsion spring 22.

This cam wheel 23 is connected via a torque setting spring 24 to a model wheel 25 serving as a torque limiter for removing overtorque.

A stopper pin 26 is provided on the cam mechanism 23 side of this model wheel 25.
is implanted, and the model wheel 25 is inserted into the cam mechanism 23 as necessary.
It can be locked to.

A pawl 27 is engaged with the mold wheel 25. This pawl 27 is pivotally supported by the peripheral end of the gear 28, and is connected to the drive torsion spring 22.
The mold wheel 25 is engaged with the mold wheel 25 against the rotational force of the mold wheel 25.

These mold wheel 25, gear 28, and cam mechanism 23 are all rotatably mounted on the support shaft 5, as described above.

The gear 28 is meshed with a drive gear 31 via idle gears 29 and 30.

This drive carrier 31 is connected to a preset cam group 36 which will be described later.
It is meshed with a driven gear 39 fixed to.

The idle gear 29 is pivotally supported by the movable frame 4, and the idle gear 30 is fixed to a gear support shaft 32 rotatably supported by the movable frame 4.

The idle gear 30 is integrated with a drive gear 31,
The output of the drive torsion spring 22 is immediately transferred to the drive gear 3.
1 can be transmitted.

The drive torsion spring 22 is driven intermittently through the CD wheel indirect coupling shaft 20 when the CD pawl 14 meshes with the ratchet gear 13 and rotates the ratchet gear 13 intermittently under the force of the feed pawl mechanism 10. It is designed so that a predetermined amount of driving energy is accumulated.

If the cam wheel 23 is wound more than necessary, the cam wheel 23 and the drive torsion spring 22 rotate in the same direction against the torque setting spring 24 to release the engagement between the pawl 27 and the mold wheel 25.

At this time, the mold wheel 25 rotates in the same direction due to the reaction force of the torque setting spring 24, and the stopper pin 2 implanted in the mold wheel 25 rotates in the same direction.
6 is locked to the cam mechanism 23, and at that point the mold wheel 25
The rotation of the drive torsion spring 2 is thereby stopped.
The excess drive energy stored in the drive unit 2 is dissipated to the outside.

During this time, the gear 28 and the drive gear 31 are maintained in a stopped state by a stopper mechanism 41 engaged with a preset cam group 36, which will be described later.

For these mechanisms, a commercially available torque limiter may be used to combine the lights.

The drive source 21 and the feed claw mechanism 10 formed in this way
A rotation angle control mechanism 33 is provided between the drive claw mechanism 10 and the rotation angle control mechanism 33 for controlling the rotation output angle of the drive source 21 according to the magnitude of the rotation angle of the feed claw mechanism 10 with respect to the pole fulcrum 9A.

This rotation angle control mechanism 33 includes an activation control section 34 that determines the activation point of the drive source 21 and releases the stopped state.
and a rotation angle control section 35 that determines the magnitude of the rotation angle after startup.

The rotation angle control section 35 includes a preset cam group 36 that is rotatably mounted on the CD vehicle indirect coupling shaft 20, and a plurality of pawl rods 37A, 37B, and 37B that lock the preset cam group 36 as necessary. ...and these multiple claw rods 37A

38B... and a driven gear 39 fixed to the preset cam group 36 and meshed with the drive gear 31.
and a ratchet locking portion 40 that unilaterally locks the CD-wheel coupling shaft 20 driven by the drive source 21 and the preset cam group 36 in the rotational direction thereof.

The preset cam group 36 includes nine disc-shaped preset cams 36A corresponding to the rotation stroke 9Δ of the pawl mechanism 10, assuming that the automatic carry is 7 digits.

36B..., each of which has a cam 36A.

36B... is a claw-like locking tooth T as shown in FIG.
1, and are integrally fixed to each other by screws or the like while retaining freedom in positioning the claw-like locking teeth T1.

Each disc-shaped preset cam 3 of this preset cam group 36
There are nine pawl rods 37A, 31B, etc. each having a locking pawl T3 at one end that can lock the locking teeth T1 as needed, corresponding to 6A, 36B... Equipped.

These claw rods 37A, 37B, etc. each have a downwardly protruding guide claw portion T4 in the center, and the other end is rotatably mounted on the horizontal rod 8B. There is.

Each of the locking claws T of the claw rods 37A, 37B...
The third side is biased by a spring or the like and is pressed against the preset cam group 36 side without contacting the preset cam group, and if necessary, any one of the pawls, for example 37A, is selected. When selected by the cam 38A, it can come into contact with the corresponding preset cam 36A.

The selection cams 38A, 38B... are disk-shaped cams, and the selection cams 38A, 38B...
There are several.

These cams 38A, 38B... have guide grooves t1 on their peripheral ends for engaging the guide portions T4 of the pawl rods 37A, 37B... t1 corresponds to the rotation angle of the horizontal rod 8A, and the pawl rods 37A, 37B.
It is fixed to the horizontal rod 8A so that the guide claw portions T3 of . . . can be sequentially engaged with each other.

That is, for example, when the feed claw mechanism 10 is in the negative place "4"
Due to the rotation angle of the feed claw mechanism 10 that occurs when hitting "5" from
so that the guide claw part T4 of A is engaged and the locking claw T3 at the tip of the claw rod 37A is brought into contact with the preset cam 36A.
The selection cam 38A is fixed to the horizontal rod 8A.

Similarly, when moving up to 10th place, select cam 38
B engages the pawl rod 37B, and when carrying up to the 100th place, the selection cam 38C engages the pawl rod 37C, and also carries from "499", which is the singular point in the 100th place, to 1500. In this case, the selection cam 38D engages the pawl rod 37D, so that the guide grooves t1 of the selection cams 38A, 38B, etc. are sequentially shifted in accordance with the rotation angle of the horizontal rod 8A. It is set.

As a result, the selection cams 38A, 38B, etc. are selected depending on the rotation angle of the feed claw mechanism 10 relative to the pole fulcrum 9A.
The claw rods 37A, 37B selected for...
One of them is the preset cam 36A,
36B..., and the locking tooth T1 comes into contact with any one of the pawl rods 37A, 37B from a preset position on the preset cams 36A, 36B...
The preset cam group 36 is urged by the drive source 21 and rotated until it is locked in the . . . , so that the rotation angle of the check digit type wheel 7 can be controlled.

In addition to the above-mentioned functions, the driven gear 39 and the ratchet locking portion 40, which are integrally equipped to the preset cam group 36, both apply rotational force in the same direction from the drive source 21 to the preset cam group 36. The rotation angle of the check digit type wheel 7 can be quickly controlled.

The ratchet locking portion 40 is connected to the CD vehicle connecting shaft 2.
The ratchet gear 40A has 20 pawl teeth fixed on the top of the ratchet gear 40A, and a locking pawl 40B that is locked when the ratchet gear 40A rotates clockwise in FIG. The locking pawl 40B is connected to the ratchet gear 4.
It always fails to engage with 0A.

The activation control section 34 of the rotation angle control mechanism 33 includes a stopper mechanism 41 extending to the ratchet locking section 40 and a check pawl 42 for checking the ratchet gear 13 integrated with the check digit type wheel I. and a release cam 43 that releases the locking state of the check claw 42 and the stopper mechanism 41, and the release cam 43 and the pole arm 9,
9 and a detachable cam mechanism 44 interposed therebetween.

The stopper mechanism 41 locks at one end a starting position setting pawl 41A that is coaxially and rotatably equipped with a locking pawl 40B that forms a part of the ratchet locking portion 40. and a fixed locking piece 41B whose other end is fixed to the movable frame 4, and this fixed locking piece 41B.
and a spring 41C that biases the position setting claw 41A in the direction of locking the position setting claw 41A.

The non-return pawl 42 is pivoted on the movable frame 4, is biased by a spring or the like, and meshes with the ratchet gear 13.

A check digit wheel holding mechanism 62 is provided connected to the check pawl 42 for the purpose of stable operation of the check digit type wheel 7 during printing operation.

This check digit wheel holding mechanism 62 includes a stabilizing pawl 63 that operates integrally with the above-described check pawl 42, and a stabilizing wheel 64 that is engaged with the stabilizing pawl 63.

This stabilizing wheel 64 is integrated with the check digit type wheel 7 on its central axis.

This prevents the ratchet gear 13 and the check digit type wheel 7 from being reversed during printing operations.

The release cam 43, which simultaneously releases the locking states of the position setting pawl 41A of the stopper mechanism 41 and the non-return pawl 42, is rotatably mounted on the CD vehicle joint shaft 20.

The attachment/detachment cam mechanism 44 locks the driven locking rod 44B at one end as necessary with a driven reverse normal rod 44B which is implanted in the removal cam 43 and is bent in the rotational direction of the removal cam 43. In addition, there is a driving locking rod 44A whose other end is fixed to the horizontal rod 8B and whose one end has a spring effect along the horizontal rod 8A, and this driving locking rod 44A is connected to the driven locking rod 44B. It normally prevents the feed pawl mechanism 10 from being locked in place, and operates only when the feed pawl mechanism 10 rotates significantly relative to the pole fulcrum 9A at the time of carrying or at a singular point, and locks the driving locking rod 44A into the driven lock. A disc cam 45 guides the stopper 44B so that it can be locked, and one end of the disc cam 45 is fixed to the movable frame 4, and just before the movable frame 4 rises and the printing unit 3 reaches the top dead center. a locking rod release member (not shown) having a function of pressing one end of the driving locking rod 44A toward the disc cam 45 and thereby releasing the locking rods 44A, 44B; A return spring 46 immediately returns the release cam 43 to its original position when the rods 44A, 44B are disengaged.

The disk cam 45 has a bulging portion 45A on the drive locking rod 44 side.
On the other hand, a slide pin 44C is provided on the drive locking rod 44A protruding from the disk cam 45 side, and this slide pin 44C
When 4C is guided to the bulge of the disc cam 45, a state is set in which the driving locking rod 44A is engaged with the driven locking rod 44B.

For example, check digit printing numbers [0,9°8.7,6,
5, 4, 3, 2. The IJs are successively implanted in this order at equal intervals and in the same direction as the rotational direction of the printing unit 3.

As mentioned above, in the case of a so-called runes check, the circulation of this number is determined in accordance with the code number, and taking into account singularities, some or all of these numbers may be cycled or skipped as necessary. By performing the following operation, check digits for all code numbers can be
It becomes possible to type out the code number at the same time.

In this embodiment, as described above, when the code number "4" in the minus digit changes to "5", the check digit after the change is 2 times larger than the check digit before the change.
The third number after skipping over the numbers (for example, the code number "24")
”, the check digit of the code number “25” becomes “7”), so the preset cam 36A is rotated 7/20 in the opposite direction and stopped. The position of the locking tooth T1 of the cam 36A is set in advance.

This is a feature of Runes Check. When the product of each digit of the code number and the weight is two digits, the two digits are added independently to obtain the check digit, so there is a weight of 2. “4” appears in the first place, making it 15.”
A singularity inevitably occurs when the

In other check digit systems, even if the product of each code number component digit and the weight becomes two digits, the check digit is determined by adding them as is, so the first digit of the code number is "4". ” to “5” does not cause a singularity.

Also, "9" appears only in the last two digits of the code number, and "...
...99" and is carried, the check digit after the carry will be the fourth digit, jumping three digits from the check digit before the carry (however, if the code number is "...・499” to “・・・50”
0", jump over 4 numbers and reach the 5th number)
Therefore, the position of the locking tooth T1 of the preset cam 36C is specified in advance so that the preset cam 36C rotates 6/20 in the opposite direction and is stopped.

If the code number changes from 1'-499J to "500", turn the preset cam 36D in the opposite direction to 5/20.
19" will appear only in the last three digits of the code number.
999'' and the next carry, turn the preset cam 36E 6/20 in the opposite direction, etc.
36 to 3 preset cams corresponding to the singularity of each digit
6I can be adjusted and installed in advance.

The movable frame 4 is housed in a base frame 50 like a normal numbering device, and is configured to be able to move up and down by being restrained by the base frame 50 together with a pressing rod 51.

Further, the inking mechanism (not shown) is the same as that of the conventional numbering device, and the operating mechanism (not shown) for the pressing rod 51, the pole arms 9, 9, and the feed claw mechanism 10 is used. ) and other basic mechanisms provided in conventional numbering devices are also provided in the above embodiment as they are.

Next, the overall operation of the above embodiment will be explained.

After setting the characters of the printing wheels 2, 2, . The cars 7 descend as one and first write out on paper that all the numbers are "0".

In response to this downward movement of the moving frame 4, the pole arm 9°9 and the horizontal rods 8A, 8B supported by the pole arms 9, 9 rotate around the support shaft 5 relative to each other. The pawl portion 10A of the feed pawl mechanism 10 and the CD pawl 14 engaged with the feed pawl mechanism 10A are rotated approximately 40° to 45° in the input direction, and the pawl 14 for the CD is engaged with the ejection position of the next consecutive code number. (that is, a position shifted by two teeth of the feed claw locking gear 1 and the ratchet gear 13).

In this case, the ratchet gear 13 is prevented from reversing by the check pawl 42, and the preset cam group 36 is prevented from rotating by the stopper mechanism 41.
The stopped state is maintained by the locking function of the pole arms 9, and the other components are simply rotated together with the pole arms 9, 9.

Next, when the external force is released from the horizontal pressure rod 51, the pressure rod 51
As in the conventional numbering device, the movable frame 4 and the pole arms 9, 9 return to their original positions by the action of a spring (not shown).

During this operation, the pole arm 9.9 rotates in the direction B in FIG.
0A locks and rotates the claw portion 1A of the feed claw locking gear 1,
The type wheel 2 representing the first digit is rotated 1/10 of a turn.

At the same time, the CD pawl 14 drives the ratchet gear 13 by 1/10 rotation in conjunction with the feed pawl mechanism 10.

This 1/10 rotation of the ratchet gear 13 is expanded to 2/10 rotation by the double angle gear mechanism 51.

Then, the check digit type wheel 7 is rotated 2/10 of a turn, thereby setting the check digit "8" for the code number "0000001" and preparing to type it out.

Furthermore, the amount of rotation of the ratchet gear 13 is 1/1
The 0 rotation is directly transmitted to the drive torsion spring 22 which forms the main part of the drive source 21 via the CD vehicle coupling shaft 20.

As a result, the drive torsion spring 22 is twisted by 1/10 rotation, and a predetermined amount of reverse rotational energy is stored.

Thereafter, the synchronous drive mechanism 11 operates repeatedly until the code number [ro OO0004J and the corresponding check digit "2" are set and preparation for ejection is completed, and the above operation is repeated, and at the same time, During this time, the drive torsion spring 22 is twisted by 4/10 turns.

Next, when printing the code number 1'-0000004J and the corresponding check digit "2", in the printing process, as the pressure rod 51 etc. is depressed and lowered,
Each part operates as follows.

First, only the pawl portion 10A of the feed pawl mechanism 10 is connected to the pawl locking gear 1.
It falls into the singularity groove by Δ.

For this reason, the feed pawl mechanism 10 rotates at a rotation angle that is approximately twice the previous rotation angle with respect to the pole fulcrum 9A. disengage with.

Specifically, the small gear 18 is rotated by the pinion 17, and the CD feed pole is moved by the arrow C via the control pin 19.
As a result, the engagement between the CD feed pawl 14 and the ratchet gear 13 is released.

Furthermore, the amount of rotation of the feed claw mechanism 10 remains the same as that of the horizontal rod 8A.
The information is transmitted to the disc-shaped selection cam 38A of the rotation angle control mechanism 33, and the selection cam 38A is rotated to select and lower the pawl rod 37A, and the locking pawl T at the tip of the pawl rod 37A is transmitted.
3 is brought into contact with the preset cam 36A of the preset cam group 36.

In this case, in this embodiment, the preset cam is arranged such that when the preset cam 36A rotates 7/20, the locking tooth T1 provided on the preset cam 36A and the locking claw T3 of the claw rod 37A engage with each other. 36A is preset.

On the other hand, the relatively large amount of rotation of the feed pawl mechanism 10 relative to the pole fulcrum 9A is directly transmitted to the disc cam 45 of the detachable cam mechanism 44, and the disc cam 45 rotates, causing the drive locking rod 44A to protrude. The slide pin 44C is pressed against the bulge 45A of the disc cam 45.

As a result, the driving locking rod 44A has its locking claw portion set at a position where it can lock with the driven locking rod 44B due to its own spring effect.

Then, when the external force is released from the pressing rod 51, the printing unit 3, check digit type wheel 7, etc. rise, and the pole arms 9, 9 relatively rotate in the direction B, as described above. During these operations, each component operates as follows.

First, the feed pawl mechanism 10 rotates the first type type wheel 2 by 1/10 of a turn to set the code number r0000005J to be printed next.

At the same time, the driving locking rod 44A of the attachment/detachment mechanism 44 becomes the driven locking rod 4.
4B and move it together with pole arms 9 and 9 to B in Figure 1.
rotate in the direction.

At this time, the release cam 43 also rotates on the support shaft 5 together with the driven locking rod 44B, energizing the check pawl 42 to disengage the check pawl 42 and the ratchet gear 13, and at the same time, the stopper mechanism 41 is Remove.

As a result, the rotation angle control mechanism 33 operates under a preset condition, and then the reverse rotational force of the drive source 21 is applied to the check digit type wheel 7.

On the other hand, in this embodiment, when the code number 4 changes to 5 as described above, the check digits before and after the change change from 2 to 9.

To explain in more detail the operation status of each part during this time, in this embodiment, the locking pawl T3 of the pawl rod 37A and the locking tooth T1 of the preset cam 36A are the same as those of the preset cam 36A.
Since they are set apart by /20 rotations, the locking pawl T3
Until it rotates and comes into contact with the preset cam 36A and engages with the locking tooth T1, the attachment/detachment mechanism 44 also rotates in the B direction due to the concave shape 7 of the pole arms 9, 9 in the B direction, and the stopper The position setting pawl 41A of the mechanism 41 and the fixed locking piece 41B are disengaged, and the check pawl 42 and the ratchet gear 1 are disengaged.
Disengage from 3.

At the next moment, the reverse rotational force of the drive source 21 is applied to the CD vehicle joint shaft 2.
0 to the ratchet gear 13.

For this reason, the preset cam 36A and the ratchet gear 13
immediately rotates 7/20, and then the locking pawl T of the pawl rod 37A
3 and the locking tooth T1 of the preset cam 36A, its rotation is stopped.

The 7/20 rotation of the ratchet gear 13 is doubled by the double angle gear mechanism 61, causing the check digit type wheel 7 to rotate 7/10 in the opposite direction to the normal rotation direction.
As a result, check digit "9" is set for code number "5".

After such an operation is performed, when the pole arms 9, 9 further rotate in the direction B and the printing unit 3 approaches the top dead center, the driving locking rod 44A of the attachment/detachment mechanism 44 locks the moving frame as described above. 4, the engagement with the driven locking rod 44B is released.

At the next moment, the return spring 46 operates to return the release cam 43 to its original position.

During this period, the position setting die 41A of the stopper mechanism 41 and the fixed locking piece 41B are on the verge of engagement, and the non-return pawl 42 is in contact with the tooth surface of the ratchet gear 13, but is not yet engaged. It is in a state where it is not completely engaged.

Then, when the pole arms 9 further rotate in the direction B, the position setting mold 41A and the fixed locking piece 41B engage, the stopper mechanism 41 works, and at the same time the non-return claw 42
is meshed with the ratchet gear 13, and at the same time, the stabilizing pawl 63 is meshed with the stabilizing wheel 64.

After these series of operations are performed, the pole arms 9, 9 further rotate slightly in the direction B, and the printing unit 3 reaches the top dead center.

Next, lower the pressure rod 51 and read the code number "00000".
05" and the check digit "9" at the same time, each part operates as follows during the downward movement of the pressing rod 51.

First, in the same way as when the press rod 51 is lowered, the printing unit 3 descends in the state set before lowering and collides with the paper surface or the like.

On the other hand, the check digit type car 7 also descends in the same state as before descending and collides with the paper surface, etc.
During this time, the end of the pawl rod 37A on the horizontal rod 8B side is pressed by a bulge (not shown) provided on the movable frame 4 and rotates in the direction E in FIG. It is removed from the target and also separated from the preset cam 36A,
Next singularity 14, 24, 34.・・・・・・94,99
Preparations are made for the selection operation of the selection cams 38A, 38B, . . . each time.

Also, when the printing unit 3 is lowered, the pole arm 9
Since ゜9 relatively rotates in the entering direction in FIG. Preparations are made to escape and again punch out the number ``6'' on the first place type wheel 2.

Then, since the feed claw mechanism 10 largely rotates in the D direction with respect to the pole fulcrum 9A and rotates together with the pole arms 9, 9, the code number r00000 is first read.
The same situation as when preparations were made to launch the 1J is reproduced.

At the same time, the amount of rotation of the feed pawl mechanism 10 is transmitted to the control pin 19 via the pinion 17 and the small gear 18, and the control pin 19 is separated from the CD pawl 14, so that the CD pawl 14 is connected to the ratchet gear 13. is engaged with.

In this case, since the CD pawl 14 rotates on the ratchet gear 13 integrally with the feed pawl mechanism 10, the CD pawl 14
The pawl 14 also prepares for rotating the check digit type wheel by 1/10, that is, the ratchet gear 13 is rotated 2 times.
It moves by the amount of teeth and meshes with the ratchet gear 13.

Through these series of operations, the driving torsion spring 22 becomes 4/1
First, code number r, except that it is twisted 0 degrees.
After striking out 000000J and the check digit "0", the exact same situation as when preparations were made to strike out the next code number "000001" and the check digit "sub" is reproduced.

Next, after the printing unit 3 prints out the code number "Q O00009J," when the press rod 51 and the moving frame 4 are raised, the pole arms 9, 9 are rotated in the direction B in the same manner as described above.

At this time, the feed pawl mechanism 10 falls into one pawl tooth portion of the printing unit 3 by 2Δ in FIG. At the same time, these are driven 1/10 rotation to prepare for ejecting code number 10.

Therefore, the rotation angle of the feed pawl mechanism 10 with respect to the pole fulcrum 9A becomes approximately twice as large as when the code number changes from code number "4" to "5".

The amount of rotation of the singular point when the feed claw mechanism 10 is carried up is transmitted to each component in the same way as the singular point (when moving from code number "4" to "5"), and in the same way, the driving source 21 is applied to the check digit type wheel 7.

At this moment, the rotation angle control mechanism 33 operates to move the check digit type wheel 7 to the type wheel 2 of the printing unit 3 as described above.
The check digit type wheel 7 is controlled to rotate 8/10 times in the direction opposite to the direction of rotation, thereby causing the check digit type wheel 7 to rotate 2/10 times in the forward direction.

During this time, the operation of each component is controlled by the position setting type 41A.
The process is performed in the same manner as in the case of the singular point described above, except that the preset cam group 36 and the ratchet gear 40A, which are connected to the vehicle joint shaft 20, rotate 8/20 times.

Then, the next operation, the lowering operation of the pressing rod 51, begins.
When the code number carried to the 10th place and the corresponding check digit are issued, during this time the check digit type wheel 7 described above is held by the check digit holding mechanism 62 and performs the printing operation, while the position setting type 41 is the idle gear 29 from the first drive source 21.
, 30.7 The preset cam group 36 is biased by the rotational force sequentially transmitted through the drive gear 31 and the driven gear 39
It rotates together with the lock, returns to the original locking position, and is reset.

After that, when the external force is removed from the pressing rod 51 and it is raised back to its original position, each component member emits the code number "5" described above and then prepares to eject the code number "6". The preparatory action for punching out the next 1st code number is performed again.

In this series of operations, each time the check digit type wheel 7 is rotated by 2/10 in the forward direction, the drive source 21 is always subjected to torsional rotation in the same direction by the CD wheel coupling shaft 20.

However, when a certain amount of torsional energy is accumulated, the drive source 21 operates to remove the remaining force from the claw 27 and automatically dissipate it to the outside, thereby protecting the drive torsion spring 22. ing.

, Next, the printing unit 3 prints the code number "...
- After launching the "9", when the pressing rod 51, moving frame 4, etc. are raised, the pole arms 9, 9 rotate in the direction B in the same manner as described above.

As a result, the feed claw mechanism 10 falls into the claw tooth portions IA and IB of the printing unit 3 by 3Δ in FIG.
The pawl locking gears 1 of the type wheels 2 for the 100th and 100th digits are meshed with each other, and the 100th digits are simultaneously driven by 1/10 rotation to change the 100th digit.

The amount of rotation of the feed pawl mechanism 10 is transmitted to each component in the same way as in the case of the 10th place carry described above, and the reverse rotational force of the drive source 21 is similarly applied to the check digit type wheel T.

At the same time, the rotation angle control mechanism 33 is activated to control the check digit type wheel 7 to rotate 6/10 in the direction opposite to the rotational direction of the type wheel 2 of the printing unit 3 as described above.

That is, the selection cam 38C selects the pawl rod 37C in accordance with the amount of rotation of the feed pawl mechanism 10 with respect to the pawl fulcrum 9A, and brings the locking pawl T3 portion of the pawl rod 37C into contact with the preset cam 36C.

As a result, as described above, the check digit type wheel 7 is rotated 6/10 times under the preset condition, and the locking tooth T3 and the locking tooth Tta on the preset cam 36B are engaged, and the check digit type wheel 7 is Rotation is stopped.

During this time, the operation of each component is performed in the same manner as in the case of the 10th place carry described above, except that the position setting die 41A rotates 6720 times in conjunction with the preset cam group 36.

Then, the next operation, the lowering operation of the pressing rod 51, begins.
After the code number carried to the 00th digit and the corresponding check digit are issued, when the external force is removed from the pressing rod 51 and it is raised back to its original position, each component will be moved to the 10th digit mentioned above. As in the case of carry printing, the preparation operation for printing out the next 1st code number is performed again.

In this case, the position setting type 41A returns to the original locking position and is reset together with the preset cam group 36, as in the case of the 10th place carry described above.

Hereinafter, when the code number becomes 1...499, the above-mentioned change in the number 1 and the carry from 1 to 10, and furthermore, the carry from 10 to 100. The same actions each performed are repeated.

And then 1 from "...499"...
・To 500.1, from "...999" to 1...
...to 1000J, and further from 1ooo to 1ooo
In the case where the carry is carried to the oo position, etc., the rotation angle control mechanism 33 is actuated by the rotational energy of the drive source 21 according to a pre-stored control value, and rotates the check digit type wheel 7 by a predetermined amount. Then, the check digits corresponding to the code numbers that are sequentially printed out are specified, and the check digits are printed simultaneously.
