Abstract

PURPOSE:To shorten the time necessary for selection of printing type wheel by arranging frequently used printing type wheels near to the center of plural printing type wheels and selecting them with priority. CONSTITUTION:When an operator sets a magazine again to a carriage 4 and confirms whether a cover of printer is closed, initialization is executed. Consequently, such motions as the carriage 4 is moved to a home position, a daisy wheel is taken out from the central storing position #3 of the magazine 8 and mounted onto a wheel motor, etc. are performed similarly with the case when a power source is thrown in. When input processing of data for defining a wheel is executed, a value of 5 corresponding to the number of daisy wheels containable in the magazine is written into a counter register CREG of RAM 42, then it is decided whether a value of 3 is written into CREG, i.e. whether it defines the storing position #3 of the magazine 8, and if the value of CREG is 3, predetermined daisy wheel information is displayed as if being inputted from a keyboard in order to store a daisy wheel which is used most frequently by a user.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[Configuration diagram of electronic typewriter (FIGS. 1 to 3)] FIG. 1 is a diagram showing the main hardware configuration of a multi-digital electronic typewriter.

In the figure, 1 is a keyboard for inputting desired print characters and various functions for functioning as an electronic typewriter. A display 2 is, for example, a two-line liquid crystal display capable of displaying 40 characters per line as shown in FIG. This display 2 is used to display characters input from the keyboard 1 or guidance and messages to the operator in a line-by-line printing mode or the like. 3 is the keyboard! This is a control unit that controls input of characters and functions to display them on the display 2, or printing operations performed by driving the carriage 4 and hammer 5, which will be described later.

The carriage 4 is equipped with a printing hammer 5, a magazine 8 that can store a plurality of wheels 6, a digiwheel 6, and other miscellaneous parts. 8 recommended. The platen 7 has a surface made of a rubber material, and is in close contact with the printing paper to feed the paper in a direction perpendicular to the six moving directions of the carriage. 6 is a disc-shaped digiwheel, with a plurality of spokes arranged radially from the center of the disc, each of which has a type attached to its tip. Reference numeral 5 denotes a printing hammer, which strikes the digiwheel 6 in order to print on paper according to instructions from the control section 3. The magazine 8 stores a plurality of diegewheels 6. The attached Digiwheel 6 can be returned to the magazine 8, and a new Digiwheel can be pulled up from the magazine 8 and replaced.

In the above configuration, when printing is instructed from the keyboard 1, the control unit 3 rotates the digiwheel 6, selects the desired print character, and inserts an ink ribbon (not shown) onto the paper surface on the platen 7. Printing can be performed by the impact of the printing hammer 5. Although not shown in Figure 1, the entire electronic typewriter is housed in a housing, and there is a cover (hereinafter referred to as the printer cover) that can be opened and closed to allow the magazine 8 to be removed. Provided. Therefore, the operator can open this printer cover, remove the magazine 8 from the carriage 4, and store a plurality of desired digiwheels in the magazine 8.
In this embodiment, a total of five digi wheels can be stored. Each storage position of the magazine 8 is given a number such as "#1" to "#5" for convenience.

FIG. 3 is a diagram showing the key arrangement of the keyboard 1.

A portion 10 for inputting numbers, alphabets, and symbols and portions 11 and 12 for instructing functions are appropriately arranged. Furthermore, an EXG" key 13 for defining the type of diegewheel in the magazine 8 is provided. Controls associated with pressing this "EXG" key 13 will be described later.

[Electronic control block diagram of electronic typewriter (Fig. 4)] Fig. 4 is a block diagram of the electronic typewriter of this embodiment seen from the viewpoint of electronic control, and the same parts as in Fig. 1 are indicated by the same symbols. .

Reference numeral 40 controls the entire apparatus by a CPtJ such as a microprocessor. 41 is a ROM in which control programs for the CPU 40, various data, table information, etc. are stored;
42 is a RAM that serves as a work area for the CPU 40 and temporarily holds information. The CPU 40 can directly give commands to the display controller 43 and buzzer controller 46, and can also give commands directly to the keyboard controller 4.
The pressed key information of the keyboard 1 can be read from 4.

On the other hand, individual controllers 49 directly related to printing operations
The command decoder 4 inputs and outputs control signals to ~55.
This is done via 7. In other words, predetermined printer instructions (commands) are prepared, and when the CPU 40 gives a command to the command decode 47, the command decode 47 checks which controller the command is directed to, and independently sends the desired operation to each controller. Although not explained in detail in this embodiment, the command decoder 4 is also equipped with a microprocessor, etc., and the printer mechanism section and data collection section are controlled by independent microprocessors, resulting in high-speed processing. We are trying to make this happen.

For example, the commands mentioned above include the following: In other words, "Print the letter 'A',""Feed the paper one line,""Store the currently installed digiwheel into the magazine," and "Turn off the carriage drive motor."
",""Initialize the printer," etc. These are set based on an encoded command system. In other words, a command is a 2-byte (16-bit) command.
The system is structured such that the first byte determines which controller the command relates to, and the second byte provides detailed operation instructions.

The cover switch 58 is a switch that is turned on and off in conjunction with opening and closing of the printer cover.
The state of 8 is input to the data bus 48 via the inverter 60. On the other hand, whether or not the magazine 8 is set in the carriage 4 is detected by a microswitch 59, and inputted to the bus 48 via an inverter 61 so that it can be manually input to the CPU 40. Also, when the output of the AND gate 62 is "1", it indicates that the magazine 8 is set in the carriage 4 and the printer cover is closed, and the output of the AND gate 63 is "1". This indicates a state in which the cover is open and the magazine 8 is not attached.

With the above hardware configuration, a description will be given of how each digiwheel in the magazine 8 is defined in the electronic typewriter. Of course, it is also possible to mark the digiwheel in advance and use a sensor or the like to read it, but in this embodiment, the cost is reduced by controlling without using expensive hardware equipped with a sensor or the like. is being measured.

[Description of Digiwheel Definition (FIGS. 5 to 9)] Hereinafter, a control method for defining a Digiwheel using a man-machine interface between an operator and an electronic typewriter will be specifically described.

First, the following four points can be considered as items that define digi-foil for electronic typewriters. That is, 1) storage location, 2) language, 3) typeface, and 4) printing pitch.

How to define each of the above items will be explained. As for the storage position of the first item, as described above, a number is printed on the magazine 8 in advance, and it is sufficient if it can correspond to that number. As for the languages in the second section, numbers are given corresponding to the main destinations of the type wheels, as shown in FIG.

For example, 5-bit data is assigned to each number, such as "1" for tJ, S, and A, and "31" for Arabia.

The definition of the font for the third item is shown in FIG. For example, Pica is “1”, Elite (
Elite) is defined as "2". As for the printing pitch in Section 4, as shown in Figure 7, for a printing pitch of 10 characters per inch, the number "
1", "4" for proportional spaces PS1 and PS2 where the printing pitch is different for each character, respectively.
“5” is defined. In this way, the language and typeface are defined in 5 bits, and the printing pitch is defined in 3 bits.

FIG. 8 is a diagram showing the configuration of the RAM 42, and 80 is a management table that stores information on digiwheels corresponding to storage positions #1 to #5 of the magazine 8.

FIG. 9 is a diagram illustrating the information storage area of one digiwheel of the table 80.

One word consists of 8 bits, and 90 is a 5-bit language information storage area shown in FIG. 5, for example, U, S,
A, "ooooo" is stored. 91 is a 5-bit storage area for storing font information shown in FIG. 6. 92
is an area for storing 3-bit print pitch information shown in FIG. In this way, it is possible to know what type of Digiwheel is stored in the Digiwheel storage position of the magazine 8. Further, the flag 93 is a 1-bit flag indicating whether or not a digiwheel is stored in the corresponding storage location of the magazine 8. This flag 93 is referred to in printing control of the electronic typewriter. In other words, when the flag 93 is "o", it indicates that there is no Digiwheel in the corresponding Digiwheel storage location.

[Description of Replacing the Wheel Cartridge (FIG. 10)] FIG. 10 is a cross-sectional view of the carriage 4, and explains the mechanism for replacing the wheel cartridge 100 that houses the type wheel.

Inside the wheel cartridge 100 is a type wheel 6.
Five wheel cartridges 100 themselves are stored in the magazine 8 in parallel. The magazine 8 can be stored by sliding it into the storage stand 101 from the side. The magazine controller 55 that moves the magazine 8 and selects wheels will be described below.

A storage stand shaft 102 passes through a part of the bottom of the storage stand 101. Further, this storage stand 101 is provided with a rack 103. The rack 103 and a gear 104 are engaged with each other, and the gear 104 is rotated by a motor 105. Therefore, the movement of the platen of the storage stand 101 in the back and forth direction (in the direction of arrow C) for reloading the wheel cartridge 1000 is performed by the rotation of the motor 105. In this way, the motor 10
5, the user can stop at the wheel cartridge that stores the desired diegewheel 6 among the five type wheel cartridges 100 in the magazine 8.

While the magazine 8 is moving in the longitudinal direction of the platen 7 (in the direction of arrow C), the vertical lever 106 continues to maintain its normal position as shown in FIG. A rack 107 is cut at the end of the vertical lever 106 opposite to the portion connected to the magazine 8, and is engaged with the gear 10B. This gear 10
8 is rotated by a motor 109.

The gear 108 is rotated counterclockwise by the rotation of the motor 109, and the rack 107 meshing with the gear 108 causes the vertical lever 106 to rotate clockwise around 111 and is lifted upward.

The entire wheel motor section, which includes components including a wheel motor 110 and a shaft 112 of the motor to which a bullet plate and a disk section are attached, is a wheel controller 50.
makes a reciprocating motion in the direction of the arrow. The vertical movement of the wheel cartridge 100 and the movement of this wheel motor section are linked, and while the wheel cartridge 100 is in the magazine 8, the wheel motor section waits at a position away from the platen 7, and when the wheel cartridge 100 is When it is lifted up by the vertical lever 106 and reaches the height of the wheel motor shaft 112, it begins to move closer to the platen 7, and finally fits into the hole in the center of the wheel and connects to the wheel motor 110. The type wheel 6 will be installed.

[Flowchart of Digiwheel definition (Fig. 11,
FIG. 12) FIG. 11 is a flowchart showing the digiwheel definition process that is started by pressing the EXG'' key 13 on the keyboard 1, and this program is stored in the ROM 41.

First, in step S1, in response to the depression of the "EXG" key 13, it is determined whether or not other processing is being executed. If another process is being executed, the process advances to step S2 and the buzzer 45 is sounded to exit this sequence. If no processing is being performed in step S1, the process advances to step S3, and the currently mounted digiwheel is dropped into the magazine 8. Stella, in step S4, turn off wJIiii, which drives the carriage motor, etc. of the printer control system. In the following step S5, it is checked by signals 64 and 65 whether the operator has opened the printer cover and taken out the magazine 8 from the carriage 4. Then, a digiwheel definition sequence step S6, which will be described later, is executed.

When step S6 is completed, the operator returns to the magazine 8.
is set on the carriage 4, and it is checked whether the printer cover is closed (step S7).

This is done by CPU 40 confirming that the output of AND gate 62 in FIG. 4 is logic "1". If this cannot be confirmed, do not proceed to the next sequence to maintain safety. Once confirmed, the sequence moves to step S.
Proceed to step 8 and initialize. This is the same as when the power is turned on, such as moving the carriage 4 to the home position, taking out the diege wheel from storage position #3 of the magazine 8, and attaching it to the wheel motor. In this way, when initializing, if the digiwheel is not installed in the printing position, the storage position # of magazine 8 is
It is decided that the Digi wheel in step 3 will be automatically pulled up and installed.

This is because it is assumed that the diegewheel stored in #3 is the one most frequently used. In addition, by storing the most frequently used diegewheel in the center of the magazine 8, the amount of movement needed to take out the wheel from the magazine 8 during normal use is reduced, reducing the average wheel replacement time. It will be possible.

FIG. 12 is a flowchart of the data input process for wheel definition in step S6 of FIG. 3411.

First, in step SIO, the printer cover opens and magazine 8
Check to see if it has come off the carriage 4. This can be determined by checking whether the output of the AND gate 63 is "1". If the conditions are not satisfied in step S10, then in step Sit a message to the operator to "remove the magazine" is displayed on the display 2 through the display controller 43. Step S
When it is confirmed by IO that the magazine 8 is removed, the process advances to step S12, and the counter register C of the RAM 42 is
Write the value "5" to REG.

This value "5" corresponds to the number of digi wheels that can be stored in the magazine. In the following step S13, CREG is set to 3.
In other words, it is checked whether storage position #3 of magazine 8 is defined.

When the value of CREG is not 3, the process advances to step S14, and C
The storage position of the magazine 8 defined based on the value of REG is displayed on the display 2 as, for example, "MG#5". In the following step S15, input of definition information defining the type of DG wheel is awaited. This is for example #5
As shown in Figures 5 to 7, if you want to define and store symbols (Greek letters), Prestage, and a 10-pitch diegewheel, select "32/15/
1'' from keyboard 1.

Note that the symbol "/" is used as delimiter information.

When the return key is pressed manually in step S16, the process proceeds to step S17, where the information input by the operator in step S15 is converted into the bit format shown in FIGS. 5 to 7, and the data shown in FIG. The configuration is stored in the corresponding storage area of the management table 80 of the RAM 42. Thereafter, the contents of CREG are decremented in step S18, and if CREG=0 is not determined in step S19, the process returns to step S13 and the above-described operations are repeated.

If the value of CREG is 3 in step S13, step S
The process proceeds to step 20, in which predetermined daisy wheel information is displayed to the operator as if input from a keyboard in order to store the most frequently used daisy wheel. For example, U, S, A, , Courie
r, if the 10-pitch wheel is the most frequently used, “
115/1''.Then, in step S21, the operator determines whether or not to follow the instructions of the device, and if it is OK to leave it as is, proceed to step S16 and input only the return key 4 from the keyboard 1.On the other hand, if you wish to change If so, proceed to step S15 and perform the same operation as described above.

Now, the flag 93 in FIG. 9 is controlled as follows. Assume that the operator inputs only the return key 4 at steps S15 and 16 in FIG. This instructs that the digiwheel should not be stored in the storage location of the corresponding magazine 8. In that case, step S1
At step 7, the flag 93 is set to 0. In other cases, the flag 93 is set to "1" to indicate the existence of a valid digiwheel.

FIG. 13 is a flowchart generally describing the determination routine for determining the approximate center position of the magazine in step S13 of FIG.

In step 5130, the number (n) of type wheels that can be stored in the magazine 8 is set in the Acc register (accumulator) of the CPU 40. In step 5131, A
The cc register is incremented by 1, and the Ace register is shifted to the right by 1 bit in step 5132 (AccxAccxl).
/2), this means that Acc is set to a value indicating the center or approximately the center position of magazine 8. Next, in step 5133, the values of Acc and CREG are compared, and if they match, the step The process proceeds to S20, and if not, the process proceeds to step S14 to execute the above-described operations.

FIG. 14 shows the values of Ace when nm5 and n=6 in correspondence with steps 5130 to 5132.

As described above, according to the present embodiment, the type of wheel can be designated and set, so that it is possible to select and print on a digi-wheel equipped with the required type, etc.

Furthermore, since the frequently used type wheel is arranged approximately in the center, there is an effect that the time required for selecting type can be shortened.

[Effects of the Invention] As described above, according to the present invention, there is an effect that a recording device can be provided in which the time required for selecting a type wheel is reduced.
