The above-mentioned connection mechanism is well known and the details thereof will be omitted.

On the other hand, when the shaft 21 is rotated counterclockwise, it is engaged with the shaft 21 and the type ring 20,
20... are rotated counterclockwise and returned (reset) to their original positions.

The type selection lever 30 described above is connected to each type wheel 20,
20..., and the other end of these levers 30 is connected to each plunger of a soinoid block 29 for character selection provided corresponding to each type wheel 20, 20... has been done. The other end of the lever 30 is linked to the coupling mechanism as described above.

On the other hand, a driven pulley 26 is attached to the shaft 21 to receive a rotational force for rotating the shaft 21 clockwise for character selection.
This pulley 26 is connected to a drive pulley 31 attached to the rotating shaft of a pulse motor 32 and a timing belt 3.
They are connected via 4.

Furthermore, a pulley 22 is attached to the shaft 21, and the other end of a spring 23 is wound around the other end of a spring 23, one end of which is fixed to the housing 4, in order to reset the type, that is, rotate it counterclockwise.

A type position signal is derived by . 25 is an ink roller attached to a rotatably supported shaft 24. 35 is a micro switch, which is closed when the sliding housing 2 is pressed down, that is, when printing is performed.

The printing device part shown in FIG. 3 above is similar to a commonly used impact printer, and the printing device part is not limited to the structure described above, and other types of impact printers can be used. it is obvious. Further, in the above example, the type wheel is rotated by the pulse motor 32, but the type wheel may be rotated by the pressing force of the sliding housing 2.

Next, the configuration of the control circuit equipped in the sliding housing 2 described above will be explained based on FIGS. 5 and 6, but first, the arrangement configuration of the keyboard 5 equipped in the sliding housing 2 will be explained with reference to FIG.

In the keyboard layout configuration shown in FIG. 4, □0 key to □9 key are numerical input keys. The □・key is the decimal point key, and the □= key is the completion key for the setting operation.

The SKP key is a key for setting the count-up number (skip number) during numbering, and after operating this key, inputting the count-up number using the numerical keys and operating the □= key sets it. For example, when "1" is input using the □1 key, the numbering is incremented by 1 each time a printing operation is performed, and 1, 2, 3, 4, etc. are printed in sequence. Also, for example, if "2" is input using the □2 key, 2,
4, 6, 8, etc. are printed sequentially. Furthermore, when "0" is input by the □0 key, the same data is printed one after another without counting up.

Also, if you want to print consecutive numbers starting from a desired value, enter the desired value using the numeric keys above, then press □=
The numerical value is preset by operating a key, and printing can be started from that numerical value.

The □− key is a hyphen key used when containing fixed information of a predetermined numerical value. For example, 54−001, 54−
To print 002, press the numeric key □5. By operating the □- key after operating □4, "54-" up to the □- key is retained as fixed information, and □-
It functions to hold the information after the key as variable information that can be changed by numbering operations.

Here, the hyphen key is used as delimiter information to separate fixed information and variable information, but the □ and □ keys can also be used in the same way. Furthermore, when this keyboard is equipped with a function key for four arithmetic operations, and the device is provided with a function as a small electronic computer, the minus key (□-key) can also be used as the hyphen key.

Next, a block diagram of the control circuit configuration of the present device shown in FIG. 5 will be explained.

Reference numeral 40 is an input circuit that supplies key signals of the keyboard shown in FIG. 4, and supplies encoded key code signals corresponding to operated keys to each circuit. That is, when various control keys (function keys) on the keyboard are operated, a key coded signal corresponding to the input key signal is supplied to the control signal generation circuit 50, and a signal corresponding to the numeric key from the keyboard and a hyphen key are supplied to the control signal generation circuit 50. When the signal is input, the information is supplied to the input buffer circuit I51.

The control signal generating circuit 50 described above is the sixth control signal generating circuit 50.
Read-only memory that stores programs for executing operations such as the flowchart shown in the figure.
It has a built-in ROM and outputs various control signals. In addition to the above-mentioned key coded signal, the control signal generation circuit 50 also receives a switch signal from the micro switch 35 for detecting printing as shown in FIG. Signals from a flip-flop that stores the state of the flip-flop are input, and various control signals (signals indicated by the cross mark) are output based on these input signals. In addition,
The symbol inside the control signal is a control signal output according to the flowchart of FIG.

52 is a register X that stores the count-up number (skip number) of numbering set by the SKP key in FIG. 4, and is opened by the control signal I→X output when the SKP key is operated. The set value is supplied via an AND gate 70 to an input buffer circuit I51.

The output of the register X52 is applied to one input terminal of the full adder circuit 54 via an AND gate 75.

Reference numeral 53 is a register Y for storing the counted up number, that is, the current numbering value, and is initially reset to the state of "0". The output of this register Y53 is AND gate 7
6 to the other input terminal of the full adder circuit 54, and is also applied to the display buffer circuit 61 and print buffer circuit 62 via an AND gate 77.

When the AND gates 75 and 76 are opened by the control signal X+Y, the full adder circuit 54 adds the contents of the register X52 and the contents of the register Y53, and inputs the addition result to the register Y53 via the OR gate 78. do.

Further, the AND gate 77 to which the output of the register Y53 is supplied has a control signal Y→DP at its other end.
At that time, the information from the register Y53 is transferred to the display buffer circuit 61 via the OR gate 79, and the information is displayed on the display device 63. The information from the register Y53 is also transferred to the printing buffer circuit 62 via the OR gate 80, and the information is supplied to the type selection circuit 64 of the printing device, where the type corresponding to the information is selected in response to the print preparation signal. be done.

55 and 56 are hyphen detection gates and flip-flops for detecting whether or not hyphen information (hyphen code) is included in the numerical information introduced into the input buffer circuit I51; If there is a hyphen code in the numerical information, the gate 55 is opened upon detection of the hyphen code, and the flip-flop 56 is set by the output of the gate 55. The set output of flip-flop 56 serves as one input of AND gate 74, and the reset output serves as one input of AND gate 73.

57 is a buffer circuit B that stores fixed information up to the hyphen mentioned above when the input buffer circuit I51 includes a hyphen code;
Of the information derived from input buffer circuit I51, only fixed information is introduced via AND gate 74, which is opened by flip-flop 56 after the detection of a hyphen.

That is, a desired numerical value can be preset in the register Y53 by operating the numerical keys and the □= key, and the register Y53 is opened by the control signal I→Y output when the □= key is operated. Input buffer circuit I51 with AND gate 71
The preset value introduced in the AND gate 7
1, is introduced into the register Y53 via the AND gate 73 and the OR gate 78.

In this case, since the flip-flop 56 is in the reset state while the hyphen code is not derived from the input buffer circuit I51, the AND gate 73 is opened and the derived information is introduced into the register Y53. If a hyphen code is derived, the flip-flop 56 is set, so the AND gate 74 is opened and the subsequent derived information is introduced into the buffer circuit B57.

For example, "54-001" is input to the input buffer circuit I51.
When the information is introduced and the □= key is operated, the AND gate 71 opens and the input buffer circuit I is first opened.
A numerical value "1" is derived from Y51, but since flip-flop 56 is in the reset state at this time, it is introduced into register Y53.

Subsequently, numerical values "0" and "0" are successively derived from the input buffer circuit I51 and introduced into the register Y53 in the same manner as described above. Then, when the hyphen code "-" is derived from the input buffer circuit I51, the flip-flop 56 is brought into the set state, so that it is introduced into the buffer circuit B57. Subsequently, the numerical values "4" and "5" are derived one after another, but since the flip-flop 56 is in the set state, they are introduced into the buffer circuit B57. In the end, variable information is stored in register Y53, and fixed information is stored in buffer circuit B57.
is input.

Further, when the information "12345" is introduced into the input buffer circuit I51 and the □= key is operated, all of the information is introduced into the register Y53 as a preset value. In other words, since there is no hyphen code, all the information is input to the register Y53 as variable information.

The register Y53 is configured such that a control signal RY is input to a reset terminal R and is reset by the signal RY.

Also, although it is similar to the above explanation, the information input to the input buffer circuit I51 is transferred to the display buffer circuit 61 via the AND gate 72 and OR gate 79, which are opened by the control signal I→D, and the input information is displayed. It is displayed on the device 63.

On the other hand, the output (fixed information) of the buffer circuit B57 described above is sent from the AND gate 81 opened by the control signal B→DP to the display buffer circuit 61 via the OR gate 79 and to the print buffer circuit 62 via the OR gate 80. will be transferred to each. The fixed information is displayed on the display device 63, and the type selection circuit 64 of the printing device selects the type corresponding to the information.

A counter _C1 58 stores the number of digits for variable information among the information introduced into the input buffer circuit I51, and a timing signal t is output for each digit when information is transferred from the input buffer circuit I51. ₁ to AND gate 82 which is opened when flip-flop 56 is in the reset state.
The number of digits of variable information is obtained by counting the timing signal _t1 . The control signal RC is input to the counter C ₁ 58 as a reset signal, and the input buffer circuit I
The operation of the counter C ₁ 58 is prohibited unless fixed information and variable information are included in the counter 51, that is, when the □- key (hyphen key) is not operated.

59 is another counter _C2 that stores the number of digits for variable information, and when adding the contents of register X52 and the contents of register Y53 (control signal
+Y output), those registers X52, Y5
The number of digits of variable information is obtained by introducing a timing signal t ₂ that is output for each digit when information is derived from 3 from AND gate 83 and counting the timing signal t ₂ . The counter C ₂
59 is reset prior to the output of the control signal X+Y, and therefore counts the number of digits of variable information each time the control signal X+Y is output.

In other words, the counter C ₁ 58 stores the number of digits for the initial input variable information, and the counter C ₂ 59 stores the number of digits for the variable information in the register Y 53 that is sequentially updated in the numbering operation. ing.

60 is the contents of the counter C ₁ 58 and the counter
This is a comparison circuit that compares the contents of C ₂ 59 and applies a coincidence detection signal to one input terminal of AND gate 84 when both counters C ₁ and C ₂ coincide. A carry signal from the full adder circuit 54 is introduced into the other input terminal of the AND gate 84. The full adder circuit 54 is designed to process each digit (4-bit processing). The output (overflow detection signal) of the AND gate 84 is introduced into the control signal generation circuit 50.

In the end, the circuit portions of the counters C ₁ 58, C ₂ 59, comparison circuit 60, and AND gate 84 perform numbering that is sequentially updated during the printing operation in response to the number of digits of the variable information at the time of input (information of the counter C ₁ 58). It constitutes a circuit that detects a state in which the number of digits of information (information in register Y53) becomes large. For example, when "54-001" is initially introduced into the input buffer circuit I51, the number of digits of variable information is The three digits of "001" have been specified, and on the other hand, when the numbering information that is sequentially updated during the printing operation finishes printing "999" and counts up next time (the full addition circuit 54
The contents of register Y53 are set to “999” in register X5.
For example, the content of 2 (for example, "1" is added) exceeds the specified digit "3", and such a state is detected.

Reference numeral 65 denotes a flip-flop _F1 which is set by the control signal _SF1 output when the SKP key is operated, and stores the operated state of the key and sends this set output to the control signal generation circuit. It has been introduced to 50.

Reference numeral 66 denotes a flip-flop _F2 which is set by a control signal _SF2 output when the □- key (hyphen key) is operated, and stores the operated state of the key and outputs this set. is introduced into the control signal generation circuit 50.

And the above flip-flop F ₁ 65, F ₂ 6
Control signals RF ₁ and RF ₂ are input to 6 as reset signals.

Next, the operation of this apparatus will be explained according to the flowchart shown in FIG.

First, when the power is turned on to this device, each circuit element is reset, and steps N ₁ ,
It cycles through a loop of N ₂ , N ₃ , N ₄ , and N ⁵ and enters a key wait state.

Here, if you want to perform a count-up operation by "1" for each printing operation, first register
Operate the SKP key to set the number of skips (count up number).

The operation of the SKP key is detected by the controller at step _N2 , and the process proceeds to step _N8 , where a control signal indicating that the SKP key has been operated is sent.
Outputs SF ₁ and sets flip-flop F ₁ 65. Steps N ₁ to _{N 5} again from this step N ₈
The program cycles through the loop and enters a key wait state, but a numeric key is operated in order to introduce the skip number.

The above numeric key (currently, the □1 key is operated to input the numeric value "1" to count up by 1) is detected by the controller at step _N1 and proceeds to step _N6 , where it is input. The numerical value “1”
is introduced into the input buffer circuit I51.

The process then proceeds to step _N7 , where a control signal I→D is outputted to display the information of the input buffer circuit I51 on the display device 62. The AND gate 72 is opened by this control signal I→D, and the information in the input buffer circuit I51 is transferred to the display buffer circuit 61 via the AND gate 72 and the OR gate 79. ” is displayed.

From the step _N7 , the loop of steps _N1 to _N5 is repeated again, and a key wait state is reached, but the □= key is operated following the numerical key.

The controller at step _N4 detects the □= key and advances to step _N18 . Now, since the SKP key has been operated and the flip-flop _F165 is in the set state, proceed to step _N24 and send the control signal.
Output RF ₁ . This resets the flip-flop F ₁ 65, followed by step N ₂₅
The process proceeds to output the control signal I→X, opens the AND gate 70, and transfers the information "1" of the input buffer circuit I51 to the register X52.

When the process further advances to step _N26 and the control signal X+Y is output, AND gates 75 and 76 are opened, and the contents of register X52 are "1" and the contents of register Y53 are "0" since they are in the initial state. is input to the full adder circuit 54 and subjected to addition processing. This addition result "1" is again introduced into the register Y53 via the OR gate 78, and the register
52 is the number of skips (count-up number information)
“1” is held. Subsequently, in step _N27 , the counter _C1 58 is reset to prohibit overflow detection (output of the AND gate 84).

Thereafter, the process proceeds from step _N27 to _N15 , _N16 , and _N17 . Therefore, the control signal Y→DP is output, the AND gate 77 opens, and the register Y53
Information "1" is transferred to the display buffer circuit 61 and the print buffer circuit 62 via the AND gate 77. Subsequently, the control signal B→DP is output, the AND gate 81 is opened, and the information in the buffer circuit B57 is transferred to the display buffer circuit 61 and the print buffer circuit 62 via the AND gate 81.

In this case, the buffer circuit B57 is in an initial state, that is, in a state where each bit is all "1", the code of all "1" bits is assigned to the zero suppression code, and the display buffer circuit B57 is
1 is being fed to the print buffer circuit 62, the information from the buffer circuit B57 is not displayed, and only the information "1" from the register Y53 is displayed on the display device 63. In addition, the printing buffer circuit 6
2, similarly, only the information "1" from the register Y53 is supplied to the type selection circuit 63 of the printing device, and type selection corresponding to the information is performed in response to the print preparation signal (step N17), and the type selection circuit ₆₃ for printing is performed. Preparations are made.

Then, from step _N17 , steps _N1 to
It circulates through the loop of _N5 and maintains the print preparation state.

Now, when a printing operation is performed in this state, the numerical value "1" is printed, and the printing is detected by the arrow at step _N5 , and the process proceeds to steps _N12 and _N13 . In the step _N12 , the control signal X+Y is output to open the AND gates 75 and 76, and the content "1" of the register X52 and the content "1" of the register Y53 are added by the full adder circuit 54, and the result is "2". is input into register Y53.

Subsequently, an overflow check is performed in step _N13 , but here, by resetting the counter C1 ₅₈ in the above-mentioned step _N27 , the overflow detection output is substantially prevented from being derived from the AND gate 84. Therefore, proceed to step _N15 .

The process proceeds from step _N15 to _N16 and _N17 , and the operation here is as described above, in which the content "2" of the register Y53 is sent to the display buffer circuit 61 and the print buffer circuit 61 for display. Type selection is performed to prepare for the next printing. Incidentally, since the information of the buffer circuit B57 contains a zero suppression code, neither display nor print selection is performed for that information.

Therefore, if the printing operation is performed sequentially, steps N ₅ ,
Repeat N ₁₂ , N ₁₃ , N ₁₅ to N ₁₇ until ``1, 2,
3, 4...'' will be printed.

In the case of the above example, when "1" is set as the number of skips to register X52, and when " ₂ " is set as the number of skips, the content of register
are added sequentially, so that "2, 4, 6, 8..." is printed.

Also, “0” is set as the skip number to register X52.
When set, in the process of step _N12 , the contents of register It will be printed.

Next, a case will be described in which desired contents are set in advance in the register Y53 as described above, and printing is to be performed from a desired numerical value.

If you operate a numeric key while waiting for a key that has cycled through the loop of steps _N1 to _N5 described above, the controller in step _N1 will detect this and proceed to step _N6 , where the entered numeric value will be sent to the input buffer circuit. I5
1. The process then proceeds to step _N7 , where the information on the input buffer circuit I51 is displayed on the display device 63.

For example, suppose that the numerical value "100" is input to the input buffer circuit I51 by operating the numerical keys.

After that, when the □= key is operated, the controller at step _N4 detects this and advances to step _N18 . At step N ₁₈ , flip-flop F ₁ 65
is in the reset state, so proceed to step _N19 .
Also in step _N19 , flip-flop _F26
6 is in the reset state, so the process advances to step _N20 . The flip-flops F ₁ 65 and F ₂ 66 are
Even if the SKP key or □- key is operated, the step will always be executed.
Since it is reset at N ₂₄ and N ₂₂ , the above steps can be performed.
In states N ₁₈ and N ₁₉ , it is in a reset state.

In step _N20 , the control signal I→X is output, the AND gate 71 is opened, and the content "100" of the input buffer circuit I51 is derived. At this time, since no hyphen code is derived, the flip-flop 56 maintains its reset state, and therefore the AND gate 73 is open. Therefore, the content "100" of input buffer circuit I51 is introduced into register Y53 via AND gates 71, 73 and OR gate 78. As a result, desired information is preset in the register Y53.

After that, proceed to step N ₂₁ and count the counter C ₁ 58.
is reset, effectively prohibiting overflow detection.

Then, the process proceeds to steps _N15 , _N16 , and _N17 , and the preset value "100" is displayed, and the character corresponding to the preset value "100" is selected, thereby preparing for printing. Note that the information in the buffer circuit B57 is also in the initial state at this time and contains a zero suppression code, so that neither display nor font selection is performed for that information.

When a printing operation is performed in the above preparation state, the numerical value "100" is printed, and the printing is detected by the arrow in step _N5 , and the process proceeds to steps _N12 and _N13 .

Here, the operation is similar to that described above, and register Y
The content "100" of register X53 and the content "1" of register Here, too, the counter C ₁ 58 is reset in step _N21 described above so that no overflow detection output is derived from the AND gate 84, so the process proceeds to step _N15 .

Steps _N15 to _N17 are the same as described above, and therefore, if the printing operation is performed sequentially, "100, 101, 102..." will be printed, and printing can be started from a desired value (preset value).

Further, in this case, if "0" is set as the number of skips to the register X52, the preset value "100" will be printed as is, and the same information "100" will be printed thereafter. Furthermore, if only the preset values are sequentially changed using the skip number ("0"), the preset values entered by the keys are printed sequentially, and therefore only the numerical values entered by the keys can be printed sequentially as they are.

Next, as described above, a desired numerical value is preset, but a case will be explained in which fixed information and variable information are included, for example, by operating the □-key (hyphen key) such as "54-001". Here, it is assumed that the skip number "1" is set in the register X52.

First, steps _N1 to _N5 are cycled in a loop, and when the numeric keys are operated to select "5" and "4" sequentially, steps _N1 , _N6 , and _N7 are advanced, and the input buffer circuit is activated in the same manner as described above. It is input to I51.

Thereafter, when the □- key (hyphen key) is operated, the arrow at step _N3 detects this and advances to steps _N9 , _N10 , and _N11 .

Here, the control signal SF ₂ is output to set the flip-flop F ₂ 66, and after introducing the hyphen code to the input buffer circuit I51, the input information is displayed and the process returns to the loop of N ₁ to _{N 5} again. .

Next, use the numerical keys to select “0”, “0”, “1”
When the input signal is operated, steps _N1 , _N6 , and _N7 are performed, and the input signal is input to the input buffer circuit I51 in the same manner as described above, and the process returns to the loop of steps _N1 to _N5 .

When the □= key is operated here, the controller at step _N4 detects this and advances to step _N18 , and since the flip-flop F1 ₆₅ is now in the reset state, the program advances to step _N19 . Since the flip-flop F ₂ 66 is in the set state here, the process proceeds to steps N ₂₂ and N ₂₃ .

At step _N22 , the control signal _RT2 is output and the flip-flop 66 is reset. Subsequently, in step _N23 , the control signal I→
Y is output, the AND gate 71 is opened, and information is sequentially transferred from the input buffer circuit I51.

In this case, as described above, the input buffer circuit I5
1 is introduced as "54-001", and when derived, it is transferred in the order of 1, 0, 0, -, 4, 5.

Therefore, since the gate 55 does not detect a hyphen code at first, the flip-flop 56 is in the reset state, and the AND gates 73 and 82 are open. 73 and an OR gate 78 to register Y53. Also at this time, the digit timing signal _t1 is sent to the counter via the AND gate 82.
C ₁ 58, the counter C ₁ 58 counts "3".

Thereafter, when a hyphen code is derived, gate 55 detects it and sets flip-flop 56, and this setting operation closes AND gates 73 and 82 and opens AND gate 74. Therefore, the hyphen code is and gate 7
1, 74 to the buffer circuit B57, and the subsequent "4" and "5" are also introduced into the buffer circuit B57.
introduced in 57.

Therefore, variable information is held in the register Y53 and fixed information is held in the buffer circuit B57 based on the hyphen code indicating a break.

The process proceeds from step _N23 to steps _N15 , _N16 , and _N17 , where the variable information in the register Y53 is transferred to the display buffer circuit 61 and the print buffer circuit 62, and then the fixed information in the buffer circuit B57 is transferred. The data is transferred to a display buffer circuit 61 and a print buffer circuit 62.

Therefore, the fixed information and the variable information are displayed on the display device 63, such as "54-001", and the type selection circuit 64 of the printing device displays the fixed information and the variable information as the type "54-001". Select and prepare for printing.

Then, from the step _N17 , the process returns to step _N1.
The printing preparation state is maintained by circulating through the loop from ~ _N5 , and when printing is performed here, "54-001" is printed, and the printing is detected at step _N5 , and the process proceeds to steps _N12 and N. Proceed to ₁₃ .

At step _N12 , the control signal X+Y is output to open the AND gates 75 and 76, and the AND gate 83 is also opened. Then, the content "1" of the register X52 and the content "001" of the register Y53 are sequentially derived one digit at a time and added, and the addition result as "002" is introduced into the register Y53.

Timing signal t ₂ output for each digit when variable information is sequentially derived from the register Y53.
is introduced into the counter C ₂ 59 via the AND gate 83, and at this time, the counter C ₂ 59 counts the timing signal for three digits (001) and becomes "3".

Subsequently, in step _N13 , overflow is determined. At this time, the count values of the counter C ₁ 58 and the counter C ₂ 59 are the same, and the comparator circuit 60
detects the match and sends the match signal to AND gate 8
4, but the full adder circuit 54
does not output a carry signal during addition processing of the registers X52 and Y53, so the AND gate 84 is closed and no overflow signal is output.

Therefore, the process proceeds from step _N13 to _N15 , _N16 , and _N17 to become ready for printing "54-002". Then, when printing operations are performed sequentially, the steps
Repeat N ₅ , N ₁₂ , N ₁₃ , N ₁₅ to N ₁₇ and select “54-
001, 54-002, 54-003,...'' will be printed.

By the way, as the printing operation is performed sequentially as described above, the variable information in the register Y53 becomes "009", and when the process proceeds to step _N12 , the first digit "9" of the register Y53 is derived and the variable information in the register Y53 becomes "009". When the first digit "1" of X52 is derived and added by the full adder circuit 54, a carry signal is output.

However, in this state, the counter
C ₂ 59 has a timing signal t ₂ of one digit that is counted as “1”, which does not match the counted value “3” of counter C ₁ 58, so no matching signal is output from the comparator circuit 60, so the AND Gate 84 remains closed. Also, counter C ₂ is “009”
The timing signal t ₂ for three digits is counted and becomes "3", which matches the value of the counter C ₁ 58. At this time, the full adder circuit 54 does not output a carry signal, so the AND gate 84 remains closed. It is held and no overflow signal is output.

Therefore, the overflow signal is output from the AND gate 84 when the variable information in the register Y53 becomes "999" and the process proceeds to step _N12 . At this time step N ₁₃
Detects overflow and steps
The program advances to _N14 , outputs the control signal RY, and resets the contents of the register Y53. Then, the process returns to step _N12 and proceeds through steps _N13 , _N15 to _N17 , and enters the preparation state.

This is because the variable information below the hyphen that is the separator is printed as a consecutive number of a predetermined number of digits, and if the above-mentioned overflow occurs, printing of a different system for the predetermined digits or more will be performed. This is to inform the public.
