DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording method and an electronic device for an electronic device, and more particularly to a recording method and an electronic device having a recording device capable of recording at three or more speeds.

[0002]

2. Description of the Related Art As an example of an electronic apparatus having a conventional recording apparatus, an electronic desk calculator (hereinafter referred to as a calculator) will be described as an example.

This calculator is provided with a printing device having a predetermined printing speed according to the model as a recording device. This printing device is operated by key operation, especially addition "+", subtraction "-", multiplication "x", division " Printing is performed in accordance with operation of function keys such as "@" and an equal key "=". For example, a full-scale commercial calculator used in a bank, company, office, or the like has a printing speed of 3.8 line /
A relatively high-speed printing device of 5 sec / sec or 5 line / sec is mounted.
A relatively low-speed printing device of ne / sec or 3 line / sec is mounted. Therefore, a user who desires high-speed printing processing, such as a bank clerk, has a printing speed of 5
A general user who purchases a model equipped with a line / sec high-speed printing apparatus and does not need high-speed printing processing, for example, generally purchases a model equipped with a low-speed printing apparatus having a printing speed of 2 line / sec. It is a target.

[0004] Conventional electronic devices with a printing device are equipped with a printing device having a different printing speed for each model as described above.
In general, the printing speed of the printing apparatus and the noise generated during printing are in a proportional relationship, so that the higher the printing speed, the larger the noise generated during printing. The printing speed and the power consumption are also in a proportional relationship, and the power consumption increases as the printing speed increases.

Accordingly, a full-scale commercial calculator used in a bank, a company, an office, or the like, in which a printing apparatus having a different printing speed for each model is mounted and the printing speed is fixed at a constant speed. In this case, since high-speed printing is always performed even when the user operates the keys late, there is a problem that noise generated at the time of printing is large and power consumption is increased. On the other hand, in the case of a popular type calculator, there is a problem that if the user becomes accustomed to key operation and the key operation speed is increased, a low-speed printing apparatus cannot follow the user's key operation.

Accordingly, an electronic device with a printing device has been proposed which solves these problems by controlling the printing speed in accordance with the key operation speed of the user. For example, one that changes the printing speed according to the key input speed (Japanese Patent Laid-Open No. 5-181805), one that changes the printing speed according to the amount of data in the key buffer (Japanese Patent Laid-Open No. 5-342165), There is one that changes the printing speed according to the amount of data in the key buffer during processing (Japanese Patent Application No. 5-13992). These are controlled so as to increase the printing speed when a high printing speed is required.

[0007]

However, in the conventional electronic devices proposed above, the printing speed may change suddenly and carelessly, for example, when a rapid key input is performed. Some people felt uncomfortable. In addition, since the printing speed is determined regardless of the type of the input key, the printing result may not be obtained promptly even when the user wants to know the printing result quickly, for example, when the equal key “=” is input.

Of course, there are a large number of print keys in which the symbols and names differ depending on the manufacturer and model, or there are many print keys having other functions. Of course, any key that prints a certain calculation result is included in the "calculation result print key". Needless to say,

The central processing unit 2 mainly comprises a processing unit 21 for executing a calculation corresponding to a key input from the keyboard 1.
And a fixed storage unit (for example, a ROM) in which a control program of the present embodiment to be executed by the arithmetic unit 21 is stored in advance.

Further, the central processing unit 2 has an output control unit 26 for outputting the operation result of the operation unit 21 to the display device 3 and the printing device 4 under the control of the operation unit 21.

Incidentally, various types of printing apparatuses are known. For example, a parallel printing system, which has a two-color printing ribbon and prints by driving the printing hammer all at once, or moves a thermal head, in which heating elements for several dots are arranged in a vertical line, to the left and right by motor driving There are known a thermal printing method in which printing is performed on thermal paper by printing, and a serial bubble jet printing apparatus in which a bubble jet head that causes a heating element to generate heat and ejects ink by bubbles is moved left and right by a motor to perform printing. ing.

The electronic calculator according to the present embodiment has a thermal printing type printing apparatus for printing on thermal paper by moving a thermal head in which heating elements 41 for several dots are arranged in a vertical line to the left and right by a stepping motor 42. 4 is used.

In the printing apparatus 4, the drive circuit 43 is connected to the output control unit 26 via the thermal register 27, and the drive circuit 44 is connected to the output control unit 26 via the motor register 28.

The heating element 41 selectively generates heat by outputting an energizing signal required for printing from the output control unit 26 to the thermal register 27 based on a control command of the central processing unit 2.

Next, the operation of the present embodiment, in particular, the processing by the arithmetic unit 21 will be described with reference to FIGS.

FIG. 2 is a main flowchart showing a printing speed control procedure of the calculator according to the present embodiment.

First, when a power supply (not shown) is turned on, the contents stored in the memory unit (MU) 23 are cleared to "0" in step S21. As a result, the flags F2 and F4 corresponding to the speed information are both set to the initial value “0”.
When the flags F2 and F4 are both “0”, the intermediate speed (3 line / s) of the three speeds is used as described later.
ec) indicates that printing was performed.

Next, after the timer (TM) value of the timer section 24 is set to 5 msec in step S22, the timer (TM) interrupt processing is turned on in step S23. As a result, a TM interrupt process, which will be described later in detail with reference to FIG. 3, is executed every 5 msec of the timer value set in step S22. Here, when a key is pressed, a process of storing the pressed key code information in the key buffer register 23a is executed.

Next, in step S24, it is determined whether or not key code information is stored in the key buffer register (KB) 23a (key buffer counter KC = 0?).
The process is performed until the key code information is stored. This is a state in which this process is repeated while the key is not operated, and is waiting for the key to be operated. Step S24
, The key is operated and the key buffer register 23a is operated.
(See FIG. 3 for details), the key buffer counter KC becomes non-zero, and the next step S
Proceed to 25. In this step S25, the key code information stored in the key buffer register 23a is called to the accumulator Acc of the operation unit 21.

Next, in step S26, "1" is subtracted from the count value (KC) of the key buffer counter (KC) 23c. This is because when the key code information is stored in the key buffer register 23a, "1" is added to the count value (KC) of the key buffer counter 23c (FIG. 3).
Therefore, when the key code information is called from the key buffer register 23a, "1" is subtracted from the count value (KC) of the key buffer counter 23c. Thus, by checking the count value (KC) of the key buffer counter 23c, it is possible to know the number of key code information stored in the key buffer register 23a.

Then, the process proceeds to a step S27 to determine whether the key code information called by the accumulator Acc is a numerical key or another key. Accumulator A
If the key code information in the cc is a numeric key, the process proceeds to step S28, where a numerical processing corresponding to the operated numeric key is executed.

Next, the process proceeds to step S29, where the display process is executed, and the result of the number input process is displayed on the display device 3, and then the process returns to step S24 to wait for a key operation again.

On the other hand, in step S27, when a key other than the numerical keys is operated and the key code information is stored in the key buffer register 23a, the flow advances to step S30 to determine whether or not the operation result print key for printing is performed. Do.
If it is a calculation result print key, the process proceeds to step S31, and a calculation process corresponding to the key code information is performed. For example, an addition process is performed for a "+" key, and a subtraction process is performed for a "-" key.

Next, in step S32, the timer interrupt operation is turned off to temporarily inhibit key capture by the timer interrupt. This is because the print processing in step S33, which is the next print processing routine, has a higher priority.
This is to prohibit key capture during the print processing routine. This print processing routine will be described later in detail with reference to FIG.

When the printing process is completed, the timer interrupt operation is turned on in step S34 to cancel the key capture by the interrupt every 5 msec. Next, step S3
After executing the process of displaying the calculation result on the display device 3 in step 5, the process returns to step S24 to enter a key operation standby state.
If it is determined in step S30 that the key is not the calculation result print key, calculation processing is performed in step S36, display processing is performed in step S37, and the process returns to step S24 to be in a key operation standby state. In this way, the processing corresponding to the key operated is performed.

FIG. 3 is a flowchart showing a key interrupt subroutine program of the calculator according to the first embodiment of the present invention.

In the figure, when a timer (TM) interrupt occurs or a key reading is called, execution is started from the processing of step S231. In this subroutine, a key code is read from the keyboard.

First, in step S231, it is determined whether or not a key has been operated, and whether or not the operated key is the first key that has not been captured. If you have
Proceeding to step S236, a return instruction is executed and the subroutine processing ends.

On the other hand, if it is determined in step S231 that the first key that has not been captured has been operated,
Proceeding to step S232, the key code of the operated key is stored in the key buffer register (KB) 23a.

Next, in step S233, "1" is added to the count value (KC) of the key buffer counter (KC) 23c. Thus, the key code is stored in the key buffer register 2
Each time one is stored in 3a, a process of adding "1" to this count value (KC) is performed, and every time one key code is read out in the main program, "1" is subtracted from this count value (KC). (Step S26), the count value (KC = KC-1) is stored in the key buffer register 2.
The value is equal to the number of key codes stored in 3a. Therefore, by examining the count value, the number of key codes stored in the key buffer register 23a can be known.

Next, the process proceeds to step S234, where it is determined whether or not the count value (KC) of the key buffer counter 23c exceeds the upper limit value.
After performing the error processing in step S236, step S236 is performed.
Is executed and the subroutine process is terminated. If the count value (KC) of the key buffer counter 23c does not exceed the upper limit value in step S234,
In step S236, a return instruction is executed, and this subroutine processing ends.

As described above, the key reading process is executed by the interrupt process every 5 msec, and the key code of the read key is stored in the key buffer register 23a. This interruption process is executed at any time other than during the printing process as described in the main program of FIG.

FIG. 4 is a flowchart showing a print processing subroutine of the calculator according to the first embodiment of the present invention.

When this print processing subroutine program is called in step S33 in FIG. 2, whether the number of key codes stored in the key buffer memory 23a is less than 5 keys in step S331 in FIG. , With reference to the count value (KC) of the key buffer counter 23c,
It is determined whether the value is 5 or less. If the count value (KC) of the key buffer counter 23c is 5 or less, the process proceeds to step S332, where the flag F2 is referred to, and the flag F2
Is "1".

When the flag F2 = 1, it indicates that the previous printing speed was high (5 lines / sec). When the flag F2 is not "1", the previous printing speed is not high (medium speed). 3 line / sec or low speed 1 li
ne / sec), a low-speed printing process is selected at this time, and a printing speed of 1 line / sec is determined in step S333.
Is printed. Then, in step S334, a flag F4 indicating that printing was performed at a low speed is set to "1", and the process proceeds to step S335. By setting it to "1", a flag F2 indicating that printing was performed at a high speed is performed. To "0"
To finish the printing process.

On the other hand, in step S332, the flag F2 = 1
When it is determined that the printing speed is high, it indicates that the previous printing speed was high-speed printing. Conventionally, low-speed printing was performed when the count value (KC) of the key buffer counter 23c was 5 or less. However, in the present embodiment, since the previous printing speed was high, the high-speed printing was directly changed to low-speed printing. Does not shift, the medium-speed printing process is selected, and the printing speed
Printing is performed at ine / sec. Next, step S3
At step S38, the flag F4 is set to "0", and
Proceeding to 39, the flag F2 is set to "0" and the printing process ends.

On the other hand, if the count value (KC) of the key buffer counter 23c is not 5 or less at step S331, the key buffer counter 2 is further processed at step S336.
Referring to the count value (KC) of 3c, it is determined whether the value is 10 or less. If the count value (KC) is 10 or less, the process proceeds to step S337, and the printing speed is set to 3 line / s.
ec, the middle-speed printing process is performed, and then steps S338, S
At 339, the flags F4 and F2 are set to "0", and the printing process ends.

If it is determined in step S336 that the count value (KC) of the key buffer counter 23c is not 10 or less, the flow advances to step S340 to refer to the flag F4.
1 or not, that is, whether or not the previous printing process was performed at a low speed. Conventionally, when the count value (KC) of the key buffer counter 23c is greater than 10, high-speed printing is performed unconditionally. In the present embodiment, the flag F4
When = 1, it indicates that the previous printing speed is low, and the process proceeds to steps S337 to S339 to perform the medium speed printing process, so that there is no direct transition from low speed printing to high speed printing.

On the other hand, in step S340, the flag F4 = 1
If not, the previous print speed is high or medium speed,
Even if the high-speed printing process is performed in step S341, the printing speed does not suddenly change. Therefore, the high-speed printing process is selected, and the flow advances to step S341 to print at a printing speed of
/ Sec is printed. Then, step S342
Then, the flag F4 is set to "0", and the flow advances to step S343. The flag F2 is set to "1", and the printing process is terminated.

When the printing process at each speed is completed and the flags F2 and F4 are set to values corresponding to the printing speed,
Proceeding to step S344, the key buffer register (K
B) Stored value of 23a and key buffer counter (KC) 2
After clearing the stored value of 3c to "0", the process returns to the main routine of FIG.

As described above, in an electronic device that controls three different printing speeds in a plurality of stages, a specific flag is set to “0” or “1” after printing at each speed, and The printing speed when performing the printing process is shifted to the next faster or slower printing speed than the previous printing speed, so it is possible to prevent extreme changes in the printing speed contrary to the user's will. Also, it is possible to provide an electronic device that does not cause a user to feel discomfort due to a change in printing speed.

(Second Embodiment) In the first embodiment, a sudden change in printing speed unintended by the user is prevented.
The transition from the previous printing speed to the next printing speed was performed smoothly.

However, when the user wants to obtain a print result as soon as possible, for example, with an equal key "=" for outputting a calculation result, the print speed may be as fast as possible. That is, the equal key “=” and the like are sufficiently recognized and input by the user. At this time, the user intends to print, but rather wants to know the result quickly. The user will not feel uncomfortable even at high speeds.

FIG. 5 is a flowchart showing a print processing subroutine of the calculator according to the second embodiment of the present invention. In FIG. 5, steps for performing the same processes as those in FIG. 4 are denoted by the same step numbers, and description thereof is omitted.

The block configuration of an apparatus for executing this embodiment and the configuration of other programs are the same as those of the first embodiment.

When this print processing program is called in step S33 in FIG. 2, the program proceeds to step S330 in FIG.
From the key code information in the key buffer memory 23a, it is determined whether or not the user has pressed a specific key that the user intends to print at a specific printing speed. In the present embodiment, the equal key “=” is pressed. Is determined. If the specific key is pressed in step S330, regardless of the count value (KC) and the previous recording speed indicated by the flags F2 and F4 (without proceeding to step 331), the specific print speed processing is unconditionally performed. In the embodiment, the high-speed printing process in step S341 is selected, and printing is performed at a printing speed of 5 lines / sec (the highest speed among three types of printing speeds) according to the equal key “=”.

If it is determined in step S330 that the key is not a specific key, the flow advances to step S331. Subsequent processes are the same as those in FIG.

As described above, according to the present embodiment, only when the user intentionally inputs a specific printing speed at a specific printing speed, the specific printing speed is given priority over other printing speed processes. Since the processing is performed, the input of a specific key, such as the equal key "=", for which the user wants to know the result quickly can be processed at a specific printing speed such as high-speed printing. In some cases, the printing speed may change abruptly to the maximum speed, but this must be sufficiently recognized by the user before key input and the user must calculate the desired printing speed to obtain the desired printing speed. Since the operation is performed with the intention of printing the result, the user does not feel uncomfortable, and the printing is performed according to the user's intention, so that the user can use the apparatus more easily.

In each of the above-described embodiments, the printing speed is controlled by using the amount of the key code (ie, the key counter value) captured in the key buffer. The printing speed may be controlled by any means. The specific key may be a specific calculation result print key other than the equal key (for example, a total equal key “* =”).

The printing speed at which printing can be performed by the printing apparatus is 3
The number is not limited to four and may be four or more.
That is, for a printing apparatus capable of printing at a plurality of printing speeds within 2 ^N (N is an integer of 2 or more), N flags are prepared as speed information, and after printing at each speed, each flag is provided. By setting the value of the flag so as to indicate the speed of the executed printing process, a person skilled in the technology having the recording device can obtain the same effect as the above-described embodiments. can do. Further, it goes without saying that the present invention may be applied to a word processor with a printer without being limited to the calculator.

[0075]

As described above, according to the present invention, an extreme change in the printing speed can be eliminated, and the printing speed does not suddenly change against the user's will.
There is an effect that the discomfort of the user can be eliminated.

That is, according to the method of the present invention, a storing step of storing key-input data in the storing means, a data processing step of performing predetermined processing on the data by the data processing means, a processing result by the data processing means, A recording step of selectively recording the key-input data at three or more stages of speeds. In the recording step, the recording speed and the storage speed selected in the previous recording are stored. Based on the number of data in the means, control is performed so that printing is performed at the same speed as the printing speed or at another speed that is one step different, so that it is possible to eliminate extreme changes in printing speed and eliminate user discomfort. can do.

According to the method of the present invention, the recording step includes the step of counting if the key-input data is data corresponding to a specific key input by the user with the intention of recording the processing result. A specific speed recording step of recording the processing result at a specific speed of a predetermined speed among three or more speeds regardless of the recording speed at the time of previous recording stored in the result and speed storage means. Therefore, even if the recording speed changes suddenly, the recording can be performed without the user feeling uncomfortable.

According to the apparatus of the present invention, storage means for storing key-input data, data processing means for performing predetermined processing on the data, and a processing result by the data processing means and the key-input data are stored. In an electronic apparatus having a recording means for selectively recording at three or more stages of speeds, the recording means uses the recording means based on the recording speed selected at the time of the previous recording and the number of data in the storage means. Since the printing is controlled so as to perform printing at the same speed as the printing speed or at another speed different from the printing speed by one step, an extreme change in the printing speed can be eliminated, and discomfort of the user can be eliminated.

Further, according to the apparatus of the present invention, the recording speed control means determines whether or not the key input data is data corresponding to a specific key input by the user with the intention of recording the processing result. And a specific speed recording means for recording the processing result at a specific speed of a predetermined speed among the three or more speeds regardless of the count result and the recording speed at the time of previous recording stored in the speed storage means. Therefore, even if the recording speed changes suddenly, the recording can be performed without the user feeling uncomfortable.
