Abstract

PURPOSE:To enable characters or symbols and graphs to be alternatively recorded, by a method wherein a typewriter mode and a graphic mode are alternately selected by repeatedly depressed a mode-selecting operating member, in a recorder using a writing means. CONSTITUTION:In the typewriter mode, character or symbol pattern data corresponding to code data inputted through keys are read from a character or symbol pattern memory (a), and a paper feeder (f), a carriage driver (g) and a writing means driver (i) are controlled on the basis of the data. When the mode is switched to a graphic mode by the mode-selecting operating member (m), a graph is drawn on the basis of graph pattern data read from a graph pattern memory (b) and numerical data inputted by operating a keyboard (c). The sizes of characters or symbols or graphs in the two modes can be easily changed by operating a common size-designating operating member (n).

Detailed Description of the Invention Technical Field The present invention relates to a method for recording characters, symbols, and graphs by relatively moving a writing instrument such as a ballpoint pen and a recording paper, and controlling the contact and separation of the writing instrument from the recording paper. The present invention relates to a recording device with a keyboard that can be easily switched between a typewriter mode in which characters and symbols can be recorded and a graph mode in which graphs can be recorded by operating various keys provided on the keyboard. It is something.

2. Description of the Related Art Devices for drawing graphs by moving a writing instrument and a recording paper relative to each other and controlling contact and separation of the writing instrument from the recording paper are already known. It is also known to change the size of graphs drawn in such devices.

However, with conventional devices of this type, it is not possible to record characters and symbols on recording paper by operating a large number of character and symbol keys provided on the keyboard, as is the case with ordinary typewriters. In order to change the size of a graph, it was necessary to create and input a program for that purpose, which made changing the size cumbersome.

Purpose of the Invention In view of the above-mentioned circumstances, the present invention provides a recording mechanism that is capable of drawing a graph by relatively moving a writing instrument and a recording sheet, and the recording mechanism is arranged on a keyboard. Characters and symbols can also be recorded by operating them in response to the operation of the character/symbol key, and by simply operating one common size specification operation member, the size of both characters/symbols and graphs can be recorded. The purpose of this invention is to provide a recording device with a keyboard that can be easily changed.

Structure of the Invention In order to achieve the above object, the recording device with a keyboard according to the present invention, as shown in FIG. a keyboard having a mode selection operation member for specifying the size of characters/symbols and graphs to be recorded;
bl a paper feeding device that feeds the recording paper supported on the paper support member in both forward and reverse directions; a carriage drive device for driving (el) a writing instrument for bringing the writing instrument into contact with and away from the recording paper; , a graph pattern memory that stores at least one graph pattern such as a line graph or a pie chart in a predetermined size, and a corresponding pattern from the character/symbol pattern memory based on the operation of the character/symbol keys on the keyboard in the fhl typewriter mode. a control device that reads data, reads graph pattern data from a graph pattern memory in graph mode, and controls the paper feed device, carriage drive device, and writing implement drive device according to each pattern data;
1. Conversion that calculates and processes the drive signals supplied from the control device to the paper feed device and the carriage drive device based on the operation of the size specification operation member on the keyboard, and converts them into a drive signal corresponding to the operated size specification operation member. and means.

The mode selection operation member can also be configured with a mode selection key that alternately selects typewriter mode and graph mode by being pressed repeatedly,
It is also possible to configure it with a two-position changeover switch. Further, the size specifying operation member may be configured by a size specifying key that sequentially specifies a plurality of predetermined sizes by being pressed repeatedly, or may be configured by a changeover switch that can take multiple positions. It is possible.

Effects of the Invention In the recording device with a keyboard configured as described above, character/symbol keys and a plurality of function keys are operated in the typewriter mode in the same manner as on a normal typewriter. Character/symbol pattern data corresponding to the character/symbol pattern data is read from the character/symbol pattern memory, and based on the pattern data, the paper feed device, carriage drive device, and writing instrument drive device are controlled, and the characters/symbols are recorded on the recording paper by the writing instrument. .

Furthermore, when the mode selection operation member is switched to the graph mode, a graph can be drawn by a combination of graph pattern data read from the graph pattern memory and numerical data input by keyboard operation.

Moreover, the sizes of both the characters/symbols recorded in the typewriter mode and the graphs recorded in the graph mode can be easily changed by operating a common size specifying operation member.

Each ballpoint pen 42 is normally held at a separate position away from the platen 12 by a presser plate 62 and a spring 64, but is moved forward by a lever 66 against the biasing force of the spring 64 and is supported by the platen 12. It is designed so that it can be pressed against the recording paper. That is, as is clear from FIG. 4, the lever 66 is rotatably supported by another lever 68 by a pin 70, and this lever 66 is movable relative to the guide rod 28 in the axial direction but not rotatable relative to the guide rod 28. The ballpoint pen 42 is pushed out to the contact position by being rotated counterclockwise in the figure by a lever 72 supported by the lever 72.

It can be rotated by 4.

The above is the presser plate 62. Spring 64. Lever 66° Lever 72. A writing instrument driving device 75 is configured that uses the guide rod 28, solenoid 74, etc. to move the ballpoint pen 42, which is a writing instrument, between a contact position where it contacts the recording paper supported by the platen 12 and a separate position away from the contact position. .

As is clear from FIG. 3, the lever 68 is biased away from the pen holder 44 by a spring 76, but as shown in FIG. 3, the pen holder 44 is held in a rotatably supported position as shown in FIG. The block member 80 is connected to the carriage 3 by a shaft 82.

The upper three digits are assigned to data representing the length of the vector, and the most significant one bit is assigned to end data indicating whether or not one character ends. Note that the direction of the vector is the 8th
Eight directions shown in the figure are prepared, and vector lengths from 0 to 7 steps are prepared, as is clear from Fig. 9. The pattern data of one character/symbol consists of a plurality of bytes, each consisting of three bytes as described above.

An example of this for A shown in FIG. 9 is shown in Table 1.

Further, the graph pattern memory 102 stores basic patterns of various graphs such as pie graphs, line graphs, and bar graphs. These basic patterns are the same as those used in conventionally well-known graphing devices, so a detailed explanation will be omitted, but each graph can display up to 12 pieces of numerical data. I'm starting to get it.

6. The recording mechanism section is provided at the rear of the recording device, and the keyboard 92 is provided at the front.
The arrangement of keys on the keyboard 92 is shown in FIG. The keyboard 92 has a number of alpha vent keys 140, similar to a typical typewriter. Symbol key 141. Including character/symbol keys such as number keys 142, space key 1
44° backspace key 146. Line feed key 148. Tab key 150. Code key 152. shift key 153,
Margin set key 154. Tab set key 156.
Repeat key 158. Function keys such as a lock key 160 are provided. The margin cent key 154 functions as a left margin set key when operated alone,
When operated together with the code key 152, it functions as a light margin set key. Also, tab set key 1

Note that 162 and 164 are pen movement keys for moving the ballpoint pen 42 to the left and right, respectively, and 1667 and 168 are paper feed keys for moving the recording paper supported on the platen 12 upward and downward, respectively. It is.

Above the keyboard 92 is a 15-digit liquid crystal display 1.
70 is provided, and the data entered manually based on the operation of each of the keys is displayed while being sequentially shifted to the left. The liquid crystal display 170 also includes an arithmetic symbol key 172 and a clear key 174 provided at the left end of the keyboard 92 for manually entering the addition, subtraction, multiplication, and division symbols and equals signs, respectively, and the numeric key 14.

It is also possible to make corrections using operations such as 8. However, these are normally symbol keys, and when operated together with the code key 152, function as an insert key and a delete key, respectively.

8. The keyboard 92 is further provided with a graph key 180 as a mode selection operation member for switching the operating mode of the recording apparatus between a normal typewriter mode and a graph mode for drawing graphs. When the graph mode is entered, a message asking about the type of graph is displayed on the liquid crystal display 170, and the number key 14 is pressed accordingly.
2, the type of graph, such as a pie chart, bar graph, or line graph, is selected.

In addition, the right end of the keyboard 92 has two modes: a mode in which characters and symbols are recorded from left to right in the normal upward position, and a mode in which characters and symbols are recorded horizontally from the upward position to the right or left from the top to the bottom of the recording paper, or A vector key 182 for selecting a recording mode from bottom to top, a color selection key 1849 for selecting the ink color of the ballpoint pen 42, and a size key 186 for changing the size of characters and graphs in stages. Line key 188 for changing the paper feed amount at line feed in stages. Further, a mode selection key 190 is provided for switching to three modes: non-print mode, collection print mode, and direct print mode when the recording apparatus is set in type 9 writer mode. The non-print mode is a mode in which numerical calculations are performed without recording characters, symbols, etc., and data entered manually is stored in the text memory 1.6, and the collection print mode is a mode in which, as mentioned above, This is a mode in which errors are corrected while the data entered manually is displayed on the LCD display 170, and then recorded on recording paper sequentially starting from the data that overflows from the LCD display 170. Direct print mode is similar to a normal typewriter. In this mode, data entered manually is recorded immediately on the recording paper.

Next, the operation of the recording device configured as described above is performed on the first F.
The explanation will be based on flowchart 1 in FIGS. 1 to 13.

As shown in FIG. 11, when the power is turned on, the initial setting of the step S1 is performed. That is, each register and counter are reset, and the carriage 30
After being returned to its original position, initial settings similar to those of a normal typewriter are performed, such as being moved to the left margin position. Along with this, the mode flag register 114 is reset, and the recording device is automatically set to typewriter mode, and a "medium" flag is set in the size flag register 126. Thereafter, step S2 is repeatedly executed to prepare the recording apparatus for key manual input. When the key is pressed manually, step S3 is executed, and it is determined whether the input code data corresponds to the size key 186.

If the result of this determination is YES, step S4
, the size is changed from "medium" to "large" (that is, the contents of the size flag register 126 are changed to data corresponding to "large"), and from then on, each time the size key 186 is operated, "large" is changed. 1 to ``Small'' and from ``Small'' to ``Medium''.
(small) is displayed. Furthermore, if the operated key is not the size key 186, a determination is made in step S5 as to whether or not the graph mode is in effect; however, since the typewriter mode is in effect as described above, the program execution proceeds to step S6. Then, it is determined whether the input code data corresponds to the graph key 180.

If the operated item is the graph key 180, step S7 is executed and the graph mode flag is set in the mode flag register 114, and a display asking the type of graph and a display of the specified size are displayed on the liquid crystal display 170. The program execution returns to step S2, but if the graph key 180 is not selected, the typewriter mode processing of step S8 is performed. This process will be detailed later.

After the graph mode flag is set in step S7, if the key is pressed manually, the determination result in step S5 becomes YES, and it is determined in step S9 whether or not the operated key is a valid key in the graph mode. It will be judged. That is, since it is not possible to record alphabento characters, symbols, etc. when the recording device is in the graph mode, if the operated key corresponds to these, the program execution returns to step S2. It is being treated as such. Note that at this time, it is also possible to configure the system so that an alarm sound is emitted or an error message is displayed on the liquid crystal display 170. If the determination result in step S9 is YES, graph mode processing in step SIO is executed, and this processing will be described in detail later.

Next, assuming that the recording apparatus is in the direct print mode, the typewriter mode processing in step S8 will be explained based on FIG. 12. In this typewriter motor routine, first, step 5
101, whether or not the end flag is set, that is, the content of the end flag register 118 is [1]
It is determined whether or not 3 is set, but since it is not set at this stage, the result of the determination is No, and step 5102 is executed. In step 5102, the first data of the pattern data corresponding to the data manually entered by the key is read by the CPU 90 from the ROM 94, and the data read in the next step knob 5103 is the last data of the pattern data of one character/symbol. It is determined whether or not it is data. Since it is not the last data at this stage, the result of the determination is No, and the program execution moves to step 5105.

In step 5105, it is determined whether the contact/separation data representing the contact/separation of the ballpoint pen in the read data represents the contact of the ballpoint pen 42. If the result of the determination is YES, a pen contact flag is set in step 5106. That is, the contents of the pen contact flag register 120 are set to [1]. Also, if the result of the judgment is No, the program execution will be stopped.
The knob 5106 is bypassed and the process moves to step 5107. In step 5107, data indicating the direction of the vector in the read data is stored in the vector direction register 122, and then in step 8108, the vector length corresponding to the specified size is stored in the vector length register 124. . That is, since the vector length data in the pattern data stored in the character/symbol pattern memory 100 corresponds to the "small" size, the size flag register 1
If the size specified by 26 is "small",
The vector length data in the pattern data read from the character/symbol pattern memory 100 is stored as is in the vector length register 124.
If a size of ``Large'' is specified, the vector length data in the pattern data is doubled and stored in the vector length register 124, and if a size of ``Large'' is specified, it is multiplied by 4 and stored. be done. That is, in this embodiment, the "medium" size is twice the "small" size, and the "medium" size is twice the "small" size.
The "large" size is said to be twice the size of the "medium J" size.

Then, in step 5109, vector direction register 122. Paper advance drive circuit 130 .based on the contents of vector length register 124 and pen contact flag register 120 . Drive signals are output to the carry knob drive circuit 132 and the writing instrument drive circuit 134, and based on these drive signals, the platen drive motor 18 and carriage drive motor 36 are driven in step 5110, and the ballpoint pen 42 and the recording paper are moved relative to each other. The printing operation is performed by moving the solenoid 74 and energizing or demagnetizing the solenoid 74. That is, either a line segment corresponding to the first read data is drawn on the recording paper by the ballpoint pen 42 with a length corresponding to the specified size, or the ballpoint pen 42 remains separated from the recording paper and the two are moved relative to each other. After that, the program execution returns to step 5101, and the same operation is repeated to record characters and symbols corresponding to the data entered manually on the recording paper.

6 Then, when the last piece of data corresponding to one character/symbol is read, the most significant bit of it contains data indicating the end, so the result of the judgment in step 5103 is YES. , an end flag is sent in step 5104. That is, the content of the end flag register 118 is set to [1]. After that, step 51 is performed as in the case where other data is read.
After steps 05 to 5110 are executed, the program execution returns to step 5101, but since the end flag is set in step 5104 as described above, the determination result in step 5101 is YES.
Step 5111 is executed. That is, vector direction register 122, vector length register 124 . Pen contact flag register 120. End flag register 11
After that, the program execution returns to step S2 in FIG. 11 and enters a standby state in preparation for the next key input.

7 Next, the graph mode processing at step 310 in FIG. 11 will be explained based on FIG. 13. In this graph mode routine, first, it is determined whether or not the key operated in step 5201 is a key for selecting the type of graph. In other words, after switching to the graph mode, which of the numeric keys 142 is operated first? If so, a flag representing the type of graph corresponding to the operated key is stored in the graph register 116 in step 5202. If the operated key is not a key for selecting the type of graph, execution of the program bypasses step 5202 and proceeds to step 5203. Step 52
In step 5203, after the graph type is selected, it is determined whether or not any of the numeric keys 142 has been operated. If not, step 5204 is bypassed and step 5205 is executed. In step 5205, it is determined whether or not the operated key is the enter key, that is, whether or not the line feed key 148 was operated in the graph mode. If so, step 5206 is executed and the data is stored in the input buffer memory 104. The data is stored in graph memory 1.
Transferred to 12. The determination result in step 5205 is NO.
If so, step 5206 is bypassed and step 5207 determines whether the operated key is the start key, that is, the space key 1 in graph mode.
It is determined whether or not 44 has been operated, and if not, the program execution returns to step 5203. That is,
For example, if two arbitrary numerical keys 142 are operated and then the enter key is operated, one piece of two-digit numerical data is stored in the graph memory 112. From now on, by repeating the same operation, Up to twelve numerical data to be shown on the graph are stored in graph memory 112.

Once the type of graph has been selected as described above and the input of numerical data to be represented on the graph has been completed, the start key is operated. Therefore, the determination result in step 5207 is YES, and in step 8208 it is determined whether the type of graph set in the graph register 116 is a pie chart, and if so, in step 5209 the type of graph set in the graph register 116 is A circle of the same size is drawn. That is, if the specified size is "small", a drive signal of a size corresponding to the data stored in the graph pattern memory 102 is sent to the paper feed device drive circuit 130 and the carriage drive circuit 132, and the If a circle with the smallest specified diameter is drawn and a "medium" size is specified, a drive signal corresponding to twice the data read from the graph pattern memory 102 is sent to the paper feeder drive circuit 130 and The data is supplied to the carriage drive circuit 132 to draw a circle with twice the diameter, and if a "large" size is specified, a circle with four times the diameter is drawn in the same way. Subsequently, in step 5210, it is determined whether all the data in the graph memory 112 has been displayed, but since the result of this determination is NO, step 5211 is executed. That is, the first numerical data stored in the graph memory 112 is read, the percentage of this numerical data to the total of the numerical data stored in the graph memory 112 is calculated, and based on the calculation result, the above A radial line is drawn that separates the circle.

Of course, even in this case, the length of the straight line corresponds to the specified size. Then step 521
In step 2, it is determined whether or not to display a percentage. If the selected graph type is a pie chart with a percentage display, the percentage display is performed in step 5213; otherwise, the percentage display is performed in step 52.
13 is not executed and the program execution returns to step 5210. Thereafter, in the same manner, the graph memory 112
The data stored in 1 is sequentially displayed on the graph, and after all the data is displayed, the determination result in step 5210 becomes YES, and graph end processing is performed in step 5223.

That is, the graph memory 112 is cleared, and the ballpoint pen 42 is returned to the position where it was before drawing the graph.

Further, if the determination result in step 8208 is NO1, that is, the graph to be drawn is a line graph or a bar graph, a frame is drawn in step 5214 according to the number of numerical data input to the text memory 106 and the specified size. In step 5215, the vertical axis is graduated in the drawn frame based on the largest value among the numerical data stored in the graph memory 112, and numerical values are attached to the scale. Next, in step 8216, it is determined whether the graph to be drawn is a line graph, and if so, in step 5217, it is determined whether all the numerical data in the graph memory 112 has been displayed. However, at this stage, the result of the determination is NO, so step 8218 is executed, and a broken line is drawn corresponding to the numerical data and specified size. If all of the numerical data is displayed, the determination result in step 5217 becomes YES, and the graph end process in step 5223 is performed.

Further, if the determination result in step 8216 is NO, that is, if the graph to be drawn is a bar graph, a determination is made in step 5219 as to whether all numerical data has been displayed, and further, in step 5220, the data is stored in the graph memory 112. A bar graph is drawn according to the stored numerical data and the specified size. Next, in step 5221, it is determined whether the data set in the graph register 116 corresponds to a bar graph with hatching. If so, hunting is performed in step 5222, and if not, hunting is performed in step 5222. ↓, the program execution returns to step 5219 without executing step 5222. If a bar graph corresponding to all the numerical data is drawn by repeating the above steps, the result of the determination in step 5219 will be YES, and step 52
23 is performed, and the program execution returns to step S2 in FIG. 11.

After one graph has been drawn as described above, if it is necessary to draw another graph, the type of graph is selected again, the specified size is changed as necessary, and the numerical data is used as the key. Another graph is drawn manually, but if there is only one graph to draw and it is necessary to record characters/symbols again, the graph key 180 is operated.

If this graph key 180 is operated in the graph mode, the mode flag register 114 is reset.
Enters typewriter mode. Therefore, ballpoint pen 4
2 to the desired position, characters and symbols can be recorded by performing the same operations as with a normal typewriter. Note that the typewriter mode is also used to express the meaning of the data shown in the graph in text.

As is clear from the above description, in this recording device 4, characters/symbols and graphs can be selectively recorded with the ballpoint pen 42 by appropriately operating the keys on the keyboard 92. , documents including graphs can be easily created, and the size key 186, which is a common size specifying operation member, can be operated both when recording characters/symbols and when recording graphs. This allows you to easily change their size to three predetermined sizes: "small,""medium," and "large."

Although one embodiment of the present invention has been described above in detail, this is literally an example, and the mechanical part of the recording apparatus.
