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 control circuit configuration installed 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 with the sliding housing 2 will be explained with reference to FIG.

In the keyboard layout configuration shown in FIG. 4, the □0 key to the □9 key are numerical input keys. □・key is decimal point key, +/- key is sign switching key, □+, □-, □÷, □
×
The keys are each function □ key in calculation mode. The □= key is the completion key for each function. The CAL key is a switching key for setting the device to calculation mode or numbering mode. Operating this key sets the device to calculation mode, that is, normal four-arithmetic calculation mode, and operating it again switches to numbering mode. In this way, mode settings are made by alternately inverting the calculation mode and numbering mode by operating the CAL key.

The SKP key is a key for setting the count-up number in the numbering mode, and after operating this key, inputting the count-up number from the numerical keys and operating the □= key sets it. For example □1
When a key is input, numbering is printed sequentially as 1, 2, 3, 4, . . . for each printing operation. For example, when the □2 key is set, 2, 4, 6, 8, etc. are printed in sequence.

The COUNT key is a key for setting the number of times the same data will be printed. After operating this key, enter the number of times using the numerical keys, and complete the setting with the □= key. For example, when the □2 key is set, the next count value will not be set until the same data has been printed twice.

The FIG key is a key for specifying the number of digits of print data. After operating this key, use the numeric keys to specify the number of digits, and complete the setting by operating the □= key. If the data equal to this number of digits is zero, "0" is printed, and the remaining digits are zero-suppressed. For example, if you specify 4 digits, printing will be repeated between 0001, 0002, ...9999.

The MR key is a key that reads the previous data stored in advance when numbering is performed following the previous one.When the power is turned off, each numbering data is stored in the non-volatile memory, and when the power is turned on next time.
By operating this key, numbering can be performed continuously from the previous time. Note that ON-OFF is a power switch.

In addition, the digit adjustment circuit 59 outputs a control signal Y→PD

In other words, of the information from the register Y53, the information corresponding to the specified number of digits is outputted as is, and a suppression code is attached and outputted to suppress zeros for digits exceeding the specified number of digits.

The output information from the digit adjustment circuit 59 adjusted in this manner is transferred to a display buffer circuit 60 and a print buffer circuit 61. The information input to the display buffer circuit 60 is supplied to the display device 44 for display, and is also supplied to the print buffer circuit 61.
The information input to the printer is sent to the type selection circuit 42 of the printer

5 and 5 respectively.

Each of these memories outputs a signal OFF in response to the detection of power OFF by AND gates 81 to 84.
When opened, it receives data from the corresponding register and buffer circuit.

Further, AND gates 85 to 88 are opened by the MR signal output when the MR key is operated, and data is transferred from each memory to the corresponding register and buffer circuit.

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 apparatus, each circuit element is reset and operation starts from step _N1 at the upper right of FIG.

Then, in response to a signal output from the power supply circuit 46 in FIG. 6 (for example, a rising signal of a DC power supply), the control signal generation circuit 56 generates a P _ON signal to operate "1→X" and "1→B" of step _N2 . is output. As a result, the AND gate 75 opens and the number “1” (0001 code) is output to the OR gate 76.
Then, the AND gate 90 is opened and the numerical value "1" (0001 code) is introduced into the buffer circuit B55 via the OR gate 73.

Subsequently, in order to operate "X+Y→Y" in step _N3 , the X+Y signal is output and AND gates 78 and 79 are opened. Therefore, register Y53
is initially in the "0" state due to the reset, but the contents of the registers X52 and Y53 are added by the full adder circuit 54, and the resultant "1" is introduced into the register Y53.

Furthermore, in order to operate "Y→PB, PD" in step _N4 , the Y→PD signal is output and the AND gate 8
0 is opened and the register Y5 is opened via the digit adjustment circuit 59.
3 is transferred to the display buffer circuit 60 and the print buffer circuit 61. At this time, since the buffer circuit A56 has been reset, digit adjustment is not performed. Further, the P signal is outputted, and the type character corresponding to the data in the print buffer circuit 61 is selected to prepare for printing (step _N5 ).

If you perform a printing operation here and now, step N ₁₁
Detect printing with the arrow and step N ₁₃ C+
Execute 1→C. In other words, the C+1 signal is output, the counter 57 counts up to "1", and the process proceeds to step _N14 , where the COMP signal is output and the comparator circuit 58 converts to the buffer circuit B.
The content "1" of the counter 55 is compared with the content "1" of the counter 57. Now, the comparison circuit 58 detects a match and sends a match signal to the control signal generation circuit 56. As a result, the process advances to _N15 , outputs the CR signal, resets the counter 57, and then proceeds to step N15.
Proceed to _N16 , output the X+Y signal, add the contents of register
53. Thereafter, the process proceeds to steps _N17 and _N18 , and the data "2" in the register Y53 is introduced into the display buffer circuit 60 and the print buffer circuit 61. At this time as well, the buffer circuit A56 is in the reset state, so no digit adjustment is performed. Furthermore, the P signal is output, and the print character corresponding to the data "2" of the print buffer circuit 61 is selected to prepare for the next printing.

If the printing operation is performed sequentially in this manner, the above-mentioned steps are repeated and consecutive numbers are sequentially printed.

On the other hand, in the preparation state for the next printing, when the FIG key is operated, the printer at step _N10 detects this and goes to the step at the bottom left of Fig. 7.
Proceed to N ₂₀ and begin digit specification operation. Then use the numeric keys to specify the digit, e.g. "4".
When inputting , "Numeric value → I" of step _N22 is executed and the numerical information "4" is input to the input buffer circuit.
Introduced in IB51. Note that when inputting the above numerical information, if the power is turned off, the process proceeds from step _N20 to step _N21 , and the power is turned off as described below.
Enters OFF operation.

Then, when the □= key is operated after inputting the numerical information, the Fig signal is output, the AND gate 72 opens, and the numerical information "4" of the input buffer circuit IB51 is passed through the AND gate 72 and the OR gate 74. Digit designation information is set in the buffer circuit A56 (steps _N23 , _N24 ). After that, proceed to step _N17 .

In step _N17 , the buffer circuit A56
Since the digit designation information "4" is set in , the digit adjustment circuit 59 outputs up to 4 digits of information from the register Y53 as is, and suppresses the digits exceeding the designated number of digits with zeros. and a display buffer circuit 60 from the circuit 59.
and is transferred to the printing buffer circuit 61. Next, the process proceeds to step _N18 , and when the P signal is output, the type corresponding to the data in the print buffer circuit 61 is selected, and preparations for printing are made again. If printing is performed here, the above-mentioned steps _N11 to _N18 will proceed, and in this case, the printing will be for the designated digits only.

On the other hand, when the COUNT key is operated in the preparation state for the next printing described above, the step
The arrow _N9 detects this and proceeds to step _N25 in the upper left corner of FIG. Further, when the number of times of printing, for example "2", is input using the numerical key, the numerical information is introduced into the input buffer circuit IB51 (steps _N25 → _N27 ). Note that if the power is turned off when inputting the above numerical information, step _N25 will not be executed.
The process then proceeds to step _N26 to begin the power OFF operation, which will be described later.

Then, when the □= key is operated after inputting the numerical information, the Cont signal is output and the AND gate 71 opens, and the numerical information "2" of the input buffer circuit IB51 is transferred to the AND gate 71 and the OR gate 7.
3 is introduced into the buffer circuit B55 (step N ₂₈ →N ₂₉ ). After that, the printer enters the printing preparation state again.

If you print here, step N ₁₁ will be executed as described above.
It progresses from N ₁₃ to N ₁₄ . In this step _N14 , the content "1" introduced into the counter 57 and the content "2" in the buffer circuit B55 are compared, and since no match is detected, the process proceeds to step _N19 to print the printed text corresponding to the data in the print buffer circuit 61. , the typeface corresponding to the same data as the previously printed data is selected again.

When printing continues, the steps start from step _N11 .
The process advances to step _N13 , where the counter 57 is further incremented by one count and becomes "2", and then, a change is performed at step _N14 . In this step _N14 , the content "2" of the counter 57 and the content "2" of the buffer circuit B55 are compared in the comparison circuit 58, and since a match is detected, the process proceeds to steps _N15 to _N18 . At step _N15 , the contents of the counter 57 are reset.

Therefore, when a printing operation is performed from now on, the buffer circuit B
The same data is printed the number of times set in 55, and consecutive numbers are printed one after another.

Furthermore, when the SKP key is operated in the preparation state for the next printing described above, the printer detects this at step _N8 and proceeds to step _N30 .
Furthermore, when a count-up number, for example "2", is input using the numerical key, the numerical information is introduced into the input buffer circuit IB51 in the same manner as described above (step _N32 ). Note that when the numerical information is input, if the power is turned off, the process proceeds from step _N30 to step _N31 , and a power-off operation described later is entered.

Then, when the □= key is operated after inputting the numerical information, a 1→X signal is output, the AND gate 70 opens, and the numerical information of the input buffer circuit IB51 is transferred to the register X52 via the AND gate 70 and the OR gate 76. (Step N ₃₂ )
→N ₃₃ →N ₃₄ ).

Subsequently, the YR signal is output to reset the contents of the register Y53 that were stored when the power was turned on (step _N35 ), and the process then proceeds to steps _N16 to _N18 .

Therefore, following the above, the X+Y signal is output, and the contents of register X52 and register Y53 are set to "2".
The full adder circuit 54 adds the content "0" and inputs the solution "2" to the register Y53, and the register X52 holds the count-up number information "2". Thereafter, the data in the register Y53 is transferred from the digit adjustment circuit 59 to the display buffer circuit 60 in the same way as described above.
and is transferred to the print buffer circuit 61, and the corresponding type is selected by the print buffer circuit 61 and becomes ready for printing again.

If you print here, step N ₁₁ will be executed as described above.
Proceed from N ₁₃ , N ₁₄ , N ₁₄ , N ₁₆ . This step
In N ₁₆ , the register X is set by the X+Y signal.
52 contents “2” and register Y53 contents “2”
are added and the solution "4" is introduced into the register Y53, and the register X52 retains the count-up number information "2" as it is. Then step
The process progresses through N ₁₇ and N ₁₈ to prepare for printing.

Therefore, if the printing operation is performed sequentially, "2, 4, 6" will be printed.
"..." will be printed.

Next, regarding the case where the MR key is operated, if the MR key was used last time and the data at that time was saved in the non-volatile memory 62 to 65, the MR key is This is the operation to be performed subsequently after the power is turned on.

Therefore, when the MR key is operated, step _N7
detect it and proceed to step _N36 . here
MR signal is output and AND gate 85~8
8 is opened and each data stored in memory x62, memory y63, memory a64, and memory b65 is transferred to the corresponding register and buffer circuit. Thereafter, the process proceeds to steps _N17 and _N18 , and the printer enters a preparation state for printing, and if printing is performed here, the printing operation can be performed following the previous operation.

Next, a case where the power is turned off will be explained.

The OFF state of the power supply is determined not only at step _N12 but also at the above-mentioned steps _N21 , _N26 , and _N31 , and upon detection of these steps, the process proceeds to step _N37 .

This outputs an off signal in response to the above-mentioned signal, opens AND gates 81 to 84, and transfers the data of buffer circuit B55, data of buffer circuit A56, data of register X52, and data of register Y53 to the corresponding memories 62 to 65. Transfer to and store. Since the memories 62 to 65 are nonvolatile memories backed up by a secondary battery power source, they retain their data even after the power is turned off.
