Abstract

PURPOSE:To return the display to the final picture based on stored data in accordance with the redepression of a guidance key by storing the display of setting of a mode in a storage part when the guidance of this mode is displayed by the depression of the guidance key during setting of the mode. CONSTITUTION:When a both sides copy key 64 is depressed and the turning-on of this key 64 is discriminated, a both sides copy set routine is executed. When a print key 54 is depressed next and the turning-on of this key 54 is discriminated, the frame code displayed before the depression of the key 54 is stored in a display code memory. Then, a copying display code is outputted to display 'copying' on a display area 69 and a copy routine is executed. When the key 54 is depressed again, stored data is restored to the frame code and is outputted, and the display is automatically returned to the same display as before copying, namely, the final picture at the mode setting time; and thus, the mode of copying is confirmed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a control device for a copying machine, and in particular to a control device for a copying machine, and in particular, in order to make it easier to use a computer which is becoming increasingly multi-functional and complicated, a full dot matrix display is provided on the operating section and the necessary minimum number of units is required. The present invention relates to an operation control device that is provided with a limited number of keys and that allows a re-operator to set a copy mode and a service person to set a service mode based on the correspondence between key operations and a display unit.

(Prior art) Copying machines have various copying modes set by the operator when using them (e.g., copy size, number of copies, magnification, density, duplex, sorter, binding margin, automatic magnification called size standardization, automatic paper selection, ADF, etc.) ) There is also something called a service mode for adjustment check sounds by service personnel or at the factory.

This shows the output status of each load inside the copier (e.g. exposure amount,
It is used to check whether the bias potential, jam sensor sensitivity, clutch, solenoid status, etc.) are normal or meet the initial setting conditions, free run mode to check sequence operation without paper feeding, load There are independent drive modes, etc. It should be noted that a self-diagnosis mode that automatically checks the status 1 of the copying machine after the main switch is turned on is also known.

The contents of various modes and abnormalities are displayed on the display section. However, many conventional copiers use pictograms to display the machine status, and some models use character displays to display information corresponding to the explanation of the pictograms above. There was no guidance, even explanations of the keys that corresponded to mode explanations.

(Purpose) The purpose of the present invention is to provide a full dot matrix display section and the minimum necessary keys on the operating section in order to make multi-functional and increasingly complex copying stages easier to use.

Reference numeral 21 indicates a separation claw, 22 indicates a conveyor belt, and 23
, 24 and 25 are trays for stocking and supplying transfer paper, 23 is a double-sided paper feeding tray, 24 is a first casing tray, 25 is a second feeding tray, 26 is a paper feeding roller unit, 2
7 is a paper conveyance unit, 28 is a separation charger, 29 is a transfer charger, 30 is a registration roller, 31 is a developer collection container for collecting old developer when replacing the developer, and 32 is a pre-transfer charger (PT'C). , 33 is a drano heater for increasing the temperature of the photosensitive drum 7, 34 is a developing unit, -
, 1, 35 is a toner cartridge for replenishing consumed toner, 36 is a drum shaft rotatably supporting the photosensitive drum 7, and 37 is a charger after cleaning.

Next, the operation of the copying machine 8 having the configuration described above will be briefly described. ! The epsilon light drum 7 is rotatably supported by a drum shaft 36 and rotates in both directions of arrows 2 and 1 in response to a copy command or the like.

Simultaneously with the rotation of the photoreceptor drum 7, the static elimination lamp 10, the pre-transfer charger 32, and the separate charger 28
, transfer charger 29, eraser 5, cleaning unit 12, and pre-cleaning/post-cleaning chargers 11.37 are driven. The cleaning unit 12 is operated under the condition that the i-source is on, so that the surface potential of the photosensitive drum 7 becomes zero after passing through the static elimination lamp IO even after a jam or the like.

The photosensitive drum 7 is driven by a main motor (not shown). In this case, the leading edge of the image is determined by the control section to be the part after the position passing the cleaning unit 12. When the photosensitive drum 12 is rotated to the normal position, the original placed on the contact glass 4 is scanned by a first carriage integrated with a first scanning mirror 14, an illumination unit 13, and the like. The reflected light image is the first mirror 14, the second mirror 16, the third mirror 15, the lens 9, and the fourth mirror 14.
The image is then formed on the photoreceptor drum 7.

After the photoreceptor drum 7 is charged by the charger 6, an eraser, that is, an erase lamp 5, illuminates unnecessary areas to create an image frame suitable for the transfer paper or the projected image, and then the photoreceptor drum is A latent image is formed on 7. At this time, in order to obtain a life-sized image,
The photosensitive drum 7 and the first carriage are driven at the same speed.

The latent image on the photosensitive drum 7 is visualized as a toner image by the developing unit 34. In this case, the developing unit 34
A dark or light image can be obtained by applying a potential to.

On the other hand, the double-sided paper feed tray 23 and the first paper feed tray 2
The transfer paper stocked in the fourth or second feeding tray 25 is fed by the paper feeding roller unit 26 until a paper detection (not shown) is activated. Next, the paper feeding roller unit 26 is operated again at the paper feeding timing, and the transfer paper is sent through the paper conveying section 27 to the registration rollers 30 that have been stopped in advance, so that the leading edge of the toner image on the photoreceptor drum 7 and the leading edge of the transfer paper The registration rollers 30 are driven at the timing that matches. The toner image on the photosensitive drum 7 is transferred to a transfer paper by a transfer charger 29. At this time, the surface of the photoreceptor drum 7 is very smooth and therefore the adhesion between the photoreceptor drum 7 and the transfer paper is strong, so by lowering the potential of the transfer paper from the separation charger 28, the photoreceptor drum 7 and the transfer paper are Reduces adhesion with. Next, the transfer paper is separated from the photosensitive drum 7 by the separating claw 21, and the thus separated transfer paper is sent to the fixing section 18 by the conveyor belt 22. Heat and pressure are applied to the toner on the transfer paper sent to the fixing section 18, whereby the toner image on the transfer paper is fixed to the transfer paper, and then the transfer paper is discharged through the reversing section 19. Ru.

Since a small amount of toner image remains on the surface of the photoreceptor drum 7 after transfer, the pre-cleaning charger 11 is activated and the surface is cleaned using the cleaning brush in the cleaning unit 12 and the pre-cleaning blade. After the next cleaning, the surface potential is made constant using the Nayager 37 and the static elimination lamp 10.

These control timings are mainly obtained from pulses generated in synchronization with the rotation of the photoreceptor drum 7 or reference pulses for driving the photoreceptor drum 7.

Next, a control system for a copying machine according to the present invention will be explained using the block circuit diagram shown in FIG.

To explain the operation section with the above configuration in more detail, the print key 54 is valid only when the copy operation is possible (when "Copy possible" is displayed in the B section display head area 70), and the copy operation is performed by pressing the print key 54. Start with.

The numeric keypad 55 is used to set the desired number of copies, and the desired number of digits can be entered using this key. The numeric keypad 55 can perform various functions in combination with various other keys. For example, deletion of a desired area of the projected image in combination with the edit key 66, special magnification change key 6
In combination with 3, it is possible to enlarge or reduce a document to a desired size, and in combination with enter key 67, it is possible to set a desired SP mode.

The paper selection key 56 selects a desired paper feed tray arranged in the copying machine (for example, the double-sided paper feed tray 23 in FIG. 1,
The first feeding tray 24 or the second feeding tray 25) can be selected.

The key 57 is used to adjust the density of the copy image.

When the interrupt key 58 is pressed during copying, the copying operation in progress is temporarily interrupted, and it becomes possible to enter another copy mode and perform copying. Furthermore, by pressing the interrupt key 58 again, the copy mode that was once interrupted is returned to.

When the clear/stop key 59 is pressed during copying, it interrupts the copying operation in progress or clears the manual force value of the numeric keypad.

When pressed, the mode clear key 60 returns the currently selected mode to the initial setting mode.

The guidance key 61 can be used in combination with an edit key 66, an image shift key 65, a double-sided key 64, a special magnification key 63, etc. to display an explanation about the mode in the display area A 69.
This is a setting key to display on the screen.

Pressing a portion of the fixed magnification/same magnification key 62 selects the same magnification, and a combination of a portion of the fixed magnification key and the cursor key 68 selects the fixed magnification.

The combination of the special magnification key 63 and the cursor key 68 enables copying at a desired image size from the original size, or selection of an arbitrary magnification (in 1% increments). When copying with a desired image size is selected, a magnification that allows the desired image size to be obtained from the original is automatically selected in combination with the numeric keypad 55. When an arbitrary magnification is selected, the desired arbitrary magnification can be selected by using a combination with the cursor key 68.

- The image shift key 65, in combination with the cursor key 68, allows the front end of the image and the leading end of the transfer paper to be shifted by a desired dimension.

Displays the contents and status of the three coins (FIG. 19), the current status of the copying machine (4th [K), etc.], etc.

FIG. 4 shows an example of the current state of the copying machine displayed in the A section display area. The graphical display indicates that the copying device is currently copying, and the setting mode currently copying is composite, 110
% enlarged copy. The display of each mode is displayed in the area corresponding to the edit key 66 and special magnification key 63, respectively.

The B part display area 70 is a fixed pattern display area, which displays the size and remaining amount of transfer paper set in each paper feed tray, the desired number of copies and the final number of copies, the density of the copied image, and the ready-to-copy display. ``Copy failed'' and the fixing roller has not reached a predetermined temperature are displayed, a door opening/closing indication, a jam indication, and no amount of toner or transfer paper remaining are displayed.

Next, display control will be explained with reference to FIG. 5, which schematically shows a part of the ProGuerra J flow, centering on the display control section.

First, when the main SW is turned on and power is supplied to the control section, a system initialization routine is executed. In this routine, in addition to setting the I10 mode and clearing RAM'M, the number of copies per copy is set to 1, and the i!
Selection of 100% magnification, etc. is executed. Next, a machine condition monitoring routine is executed, and in this routine, remaining jammed paper is checked, door 0PEN is checked, paper feed tray paper size is read, etc.

After such a check, the jam flag or door 0PEN flag is determined, and if these flags are set at that time, the display code (NJ
A, 4. Noor) is output to the operation section (display section), and displays indicating these machine conditions are displayed on the pictorial display section (section B display area 70 in FIG. 3) and the full dot display section (section A display area 69 in FIG. 3). will be displayed.

Next, enter key 67 and clear key 60 are turned on at the same time.
It is determined whether or not the SP mode has been called. If the SP mode has been called, an SP mode processing routine, which will be described in detail later with reference to FIG. 7, is executed.

Next, it is determined whether the special magnification key 63 is ON, and if it is ON, a special magnification setting routine is executed, and the display shown in FIG.
9 will be displayed. This mode includes zoom mode, standard size mode (a mode that detects the original size and automatically determines the magnification ratio to make the specified paper size), and dimension magnification mode (entered using the numeric keypad 55). There are three modes (a mode in which the magnification ratio is automatically determined based on the copy size TI method entered from the numeric keypad 55 as well as the specified original dimensions), and these modes can be selected using the cursor keys 68. υ・di is done.

Next, the double-sided copy key 6.1 is set to ``-11'' and 0.
If so, the duplex copy setting routine is executed. At this time, the display shown in FIG. 14 is displayed in the A section display area 69 as the first screen. There are three modes in this mode: single-sided/double-sided copy mode, double-sided original/double-sided copy mode, and double-sided original/single-sided copy mode, and these modes are similarly selected using the cursor key 68.

Next, it is determined that the image shift key 65 is ON, and the image shift key 65 is turned ON.
If so, the image shift setting routine is executed. At this time, the display shown in FIG. 15 is displayed as the first screen in the A section display head area 69.

In this mode, you can use the cursor key 6 to press the cursor key to move the left and right margins for single-sided copying, and the left and right margins for both sides of the copy.
It can be set in 8.).

Next, it is determined whether the edit key 66 is ON, and if the edit key 66 is ON, an edit mode setting routine is executed.

This routine will be described in detail later in the flowchart of FIG. 6, and the display shown in FIG. 16 is displayed in the A section display head area 69 as the first screen. This mode includes a trimming mode (a mode in which only the image of the area data inputted by the cursor key 68 is left), a masking mode (a mode in which the image of the area data inputted by the cursor key 68 is erased), and a composite copy mode ( There are three modes: a mode that copies the images of two originals onto the same copy paper (in this case, the first original may be in trimming mode and the second original may be in masking mode), and these The mode is selected by cursor key 68.

Next, it is determined whether the guidance key 61 is turned on, and if it is turned on, a guidance display routine is executed. This routine will be described in detail later in the flowchart of FIG. 11, and the display shown in FIG. 17 is displayed in the A section display area 69 as the first image plane. This mode includes a key explanation mode (a mode that explains the keys pressed in this mode), a consumables supply and paper removal explanation mode,
There are three modes: and a display explanation mode (picture explanation mode in the B section display area 70), and these modes are selected by the cursor key 68.

Next, it is determined whether the machine is warming up, and if it is, a warm-up display code N is displayed.
w u e is output to the production department. Please wait 2 in the circle.
Turn on the display.

Finally, it is determined that the print key 54 is ON, and if it is ON, the frame code N that was displayed before this key 54 was pressed is stored in the display code memory DCA, and the display code during copying is stored. N. , and the text "Copying in progress" is displayed in the Δ section display area 69, and at the same time, the copy routine is executed. When the copy is completed, the memorized data is returned to the frame code N and output, and the display is automatically returned to the same display as before the copy, that is, the final screen when the mode was set, so that it is possible to see what kind of copy was made. ing.

In addition, since the jam flag check and door open flag check are dominant routines, if the above flag is set while setting each mode, the display during each mode setting will be ignored and the jam display or door open flag will be ignored. Display will take priority. In addition to this, there is also an abnormality display (serviceman call display) based on a self-diagnosis function.

FIG. 6 is a partial detailed flowchart of the routine described as the edit mode setting routine in FIG.

In the figure, when this routine is entered by turning on the edit key 66, the I collection keys LF and D are lit to indicate that this mode has been entered.

Next, Eo, which is the base code in the edit mode, is output as a frame code to the operation section, and the display shown in FIG. 16 as described above is performed as the first display.

Next, it indicates which cursor key LED is to be lit from the frame code N, that is, the effective cursor key in that frame code N (also, at this time, the A section display head area 6
In order to display the cursor key in 9 by painting the corresponding cursor key black, the cursor key LED is lit according to the cursor key LED lighting routine corresponding to N. When the W4fi key 66 is turned on again in this state, the edit key LED is turned off and this mode is exited.

Next, as shown in FIG. 22, it is determined whether cursor key b is turned on in the cursor keys 68 marked with symbols, and if it is turned on, it is determined whether cursor key b is valid. This means that cursor keys b and c are set to 0N10FF to select trimming, masking, and composite copy as described above, but in the case shown in FIG. 16 (trimming is selected), cursor key C
is invalid, and when composite copy is selected, cursor key b is invalid. When cursor key b is valid, subfunction code C8F indicating each subfunction of trimming, masking, and composite copy is incremented. Similarly, when cursor key C is turned on, the validity of cursor key C is determined, and if it is valid, subfunction code C5
F is decremented. c modified in this way
It is determined whether sr is O, 1, or 2, and the corresponding frame code Eo+E0+ is determined and output. At the same time, the cursor keys (a, b) are valid.

The cursor key LED is lit again in the cursor key lighting routine as shown in c, d) (corresponding portions (a, b, c, d) of the cursor key 68 in the A section display area 69).
Copy mode C8,4, which is a machine control code (displayed in black), is given as CSt+1. The reason why C3F is incremented here is because the initial data of C3M is 0 (indicating that nothing is set).

When cursor keys a and d are turned on, area data is set by an area data setting routine in trimming mode and masking mode.

Next, when the guidance key 61 is turned on during mode setting, the guidance key 61 in the mode setting (this content is
Guidance necessary for setting this mode is displayed in the flowchart shown in the figure (described in detail later).

Next, when the print key 54 is turned on, the frame code N that was displayed before it was turned on is transferred to the display code memory D.
Stacked on CM, display code N9 while copying. is output to the operation unit. And then subframe code NS 1
-C,, Outputs the NSI as +1 to the operation unit. As shown in FIG. 12, the A part display area 69 includes the part determined by the frame code N, NS1 (indicating the sub-function of 'tJjA collection mode), N52 (indicating the binding mode setting), and NS3. (indicates a sub-function of duplex mode), and S4 (indicates a sub-function of special magnification change). In other words, in this case, the frame code N
The text “Copying in progress” is displayed for the part determined by
For the portion to be determined by SI, either "trimming", "masking", or "synthetic copy" is displayed by the value of N S 1 (see FIG. 4).

When the copy routine is executed while displaying the above and the copy is completed, the value of DCM is returned to N, and N S 1
= 0 and is output to the operation unit to return to the display before copying.

The flowchart following "S" in the flowchart of FIG. 6 is shown in FIG. 23, and this flowchart will be explained below. This flowchart shows that after the sub-functions (trimming, masking, composite copy) in the edit mode are set, other modes (special magnification mode, duplex mode (composite copy) cannot be set at the same time) ), image shift mode). That is, when a mode key other than the edit key 66 is turned on, this flow starts. When this flow is entered, the editing key LED is turned off, Csy+1 is sent to the operation unit as N5l (subframe code 1), and the process moves to the mode setting routine for the key that was turned on.

In the other mode setting routine that has been transferred, the LED of that key is lit and the base frame code of that mode is output to the operation unit, similarly to this ti key setting routine. However, since Csy+1 is sent as NSI first, the part corresponding to NS1 of the new part A display θIyi69 contains any of the set words "trimming", "masking", or "synthetic copy". Is displayed. In addition, L is a press confirmation device for each mode key.
ED is determined by the frame code N as described above. FIG. 7 is a flowchart showing part of the SP mode processing routine. As shown in the figure, when entering this routine by turning on the enter key 67 and the clear key 60 at the same time, the base code S
P o is output as frame code N to the operating section. Next, a person other than a service person can operate each dip switch (DIPSW) or digit switch (Digital switch) in this mode.
The serviceman code input routine (SPID code input routine) is entered to receive the serviceman code without operating the tSW). Enter key 67 ON
The input 5PXD code is compared with a constant 1□, and if there is a mismatch, the routine automatically returns to prevent manipulation by someone who does not know the code.

If the 5 PID code fails, the 3. is added and output as a frame code (N=SP o 13). In this mode, the display changes from the memory N0 manual display in SP mode.

Next, simultaneous ON of the enter key 67 and the clear key 60 is determined, indicating the normal return point from this routine. When turned ON, specific 1) IPSW bits are reset (free run bit, inching bit, self-diagnosis function stop bit, specific load operation bit, etc.) to prevent forgetting to reset them.

Memo IJN. When the memory N0 is input and the enter key 67 is turned on in the S P M N input terminal, the frame code is SPO, and S P M N are added (directly (N = S P 6 + S P M N
) and then it is determined whether S P M N is a constant equal to or less than 14.

If this is the case, it is not the most winter frame, so the timer T is turned on, and then it is determined whether the guidance key 61 is turned on or the timer counts up.

When the guidance key 61 is ON, the display returns to the state before entering this routine and jumps to "mouth". When the timer counts up, the incremented N is output, and if the timer does not count up, the guidance key 61 is pressed again.

That is, when you want to see guidance for a mode during mode setting, you can execute the guidance display by pressing the guidance key 61 at any time, and you can return to the original setting mode by turning the guidance key 61 on again at any time. .

FIG. 11 shows a part of the guidance display routine shown in FIG. The mode in which this routine is entered by turning on the guidance key 61 is the normal guidance mode, and the guidance mode that allows you to enter the copy mode is the 111th! As described above regarding i.

In FIG. 11, when the normal guidance mode 1 is entered, the guidance key LED is lit and the guidance flag F' is activated. be set. Next, the display frame code 1'N before entering the routine is stored in the display code memory DC~

Next, the valid cursor keys ■ and ED are cursor keys L E
It is lit by the D lighting routine and the guidance key 6
1 is determined to be ON. When the guidance key 61 is turned on, the data in the display code memory DCM is returned to N and output. This routine is returned by resetting the guidance flag FG and turning off the guidance LED.

When the cursor key b is turned on, the "B consumable supply paper removal mode" or the "C display explanation mode" shown in FIG. 17 is executed by the B or C guidance routine. After completing this routine, jump to the "G" section.

"Explanation of the A key When the special scaling key 63 is turned on in mode j, the special scaling key LED lights up, and then the value obtained by adding Go and a constant is output as a frame code.N is incremented, and then it is determined whether it is equal to GO+Kh (constant). If it is determined that they are equal, the guidance that was displayed earlier is the d'd frame of the special variable key guidance, so the special variable key guidance is Double key LE
Turn off the D light and jump to the "G" section.

If N f - G , + K b, timer 'F is O.
After that, it is determined whether the guidance key 61 is turned on, any key other than the special magnification key 63 is turned on, and the timer T is counted up. In this case, if the guidance key 61 is ON, the program jumps to the "to" section. When a key other than the special magnification key 63 is turned on, the guidance for the other keys is executed by jumping to the "chi" section. When the timer T counts up, the incremented value N is output. If the count has not increased, the process returns to determining whether the guidance key 61 is ON.

Similar to turning on the special magnification key 63, the double-sided key 64,
The image shift key 65 and the growth key 66 are turned on to implement guidance. Guidance other than these keys can also be implemented.

Figure 21 is a modification of the flow from Figure 11 after the specific key guidance ends (when N'' Go + K b is established), and the flow is changed to enable transition to the setting mode for that specific key. It is.

When N "" Go + K b is established, it is output as 7 (constant) to the frame code Go +. The display in the A section display area 69 at this time is shown in FIG.

When cursor key a is turned on, the mode shifts to the setting mode of the key that was providing guidance up to that point, that is, the setting routine of the special variable magnification mode in this case, but before that, the kaidance flag is reset and the guidance key LED is turned on. The lights are turned off.

When the cursor key b is turned on, the special magnification key LED is turned off and the process moves to "g" in FIG. 11, similarly to the flowchart in FIG.

When the guidance key 61 is turned on, "Go" in FIG.
and return from the guidance routine.

In this way, when setting a mode, the key and mode are first recognized by the guidance, and the user can proceed directly to the routine for setting the mode.

Next, each circuit component will be described in detail based on FIG. 24 showing the display circuit configuration used for display control of the present invention.

In Figure 24, ICl0I as a CPU has 80
I am using 88. This 8088 is an 8-bit CPU, internal processing is a 16-bit CPU, and an external address space is a 1 Mbyte CPU. The reason why this CPU is used in the present invention is that the display content data + control of the liquid crystal full-dot section, that is, the A section display area 69 of the operation section, is 64 bytes (in a normal 8-bit CPU, the external address space is 64 bytes). This is because it goes far beyond the current situation. In this case, a bank system may be considered, but bank switching management on software becomes complicated.

ADO~7 of ICl0L is IC103 (74LS373) which performs switching with address data by time division.

A peripheral LSI such as II (8259) is selected.

Here, the address map in this circuit is explained using FIG. 25, and as shown in FIG. 2, ten 32-byte ROMs are allocated from 00000H to 4FFFFH and used. In this assignment, 60000H to 600H

As is clear from FIGS. 24 and 25, ten ROMs 0 to 9 are used in this circuit configuration.

ICl0I starts from FFFFFOH after being reset. From FIG. 24, Y15 of IC 105 becomes L and C3I is selected (ROMI is selected). ROM
By setting the JMP command and the jump destination address (initialization start address) from address FFFOH of I, the machine can be initialized after reset.

ROM O40 (OOOOOH~0FFFFH) contains a program for processing messages for display, as well as the CPU (main body of the machine). ROM 2~6 (100O

The transfer of signals between the host CPU (machine main body) and the operating section will be explained based on FIGS. 26 and 27. Figure 26 shows the timing of data transfer between the operation unit CPU and the main body CPU. O1), PAO-P

When this happens, the CPU 2 knows that the data has been taken in, and sets the strobe PCO to L. CPUI strobe PCO is 1. When this happens, the latch PBO is returned to L. By repeating the above, data is transmitted from the CPU on the main body (CPU1) to the CPU on the operating section side (CPU2), and the CPU on the operating section receives data from the CPU on the main body.

The liquid crystal dot matrix (64X
256) Describe the module. FIG. 28 shows the circuit of this liquid crystal dot matrix module.

The LCD driver ICs 201 to 207 (segment side) and IC
There is 208 (common side).

The LCD 201 is a 64x256 dot matrix, but the upper side is 32x256 and the lower side is separated into 32x256. By doing this, 6
Although it is 4x256 full dots, it can be driven with a duty of 1/32, and the contrast is better than that with a duty of 1/64. However, there is a drawback that three drivers (ICs 205 to 207) are required on the segment side, which increases the cost. In this embodiment, the disadvantage of 7゛-low cost is ignored and priority is given to improving the contrast of the display.9 Figure 24<7) IC10G (lID61a30)
Liquid crystal dot matrix module: L-le LCD201

I-d, Cl3 and DI).

After outputting one line of data (512 pieces), CLI-d latches the data into the segment side liquid crystal driver ICs 201 to 207. For IC201-208, commercially available liquid crystal display (LCD) drivers were used.

FIG. 31 shows a block diagram inside this liquid crystal display display. This driver consists of an 80-bit shift register 71, an 80-bit latch section 72, and a liquid crystal display driver 73. For more detailed configuration, see L.
Since it will become clear by referring to the CD driver data book, the explanation will be omitted here.

The common side output of this driver is the signal CLl- in FIG.

, Y 2 ′ −−−−−−−−1·, Y32 at t32. By repeating t 1 - t 32 - L L - t 32 scanned by a line selected as Y32', the human eye can see information such as letters and pictures on a 64 x 256 dot panel. It looks like it's been done.

Next, the circuit of the picture display section shown in FIG. 32, that is, the liquid crystal module in the B section display area 70 of FIG. 3 will be explained. Liquid crystal display LCD20 used in the figure
2 is a guest-host type liquid crystal. Transmissive liquid crystals can also be used, but the characters, pictures, etc. on the picture display panel are color-coded by colors such as red, yellow, and green, and color filters are provided for each area on the base. In this embodiment, a guest-host type is used so that the color of this base (other than the pattern to be lit) is not visible. Further, the duty of the picture display liquid crystal is driven at 2.

The drivers IC301 and 1c301 are HD61602 manufactured by Hitachi, one of which is a mask and the other is a slave.There is a display RA inside the driver 1c301.
By setting display data in this RAM, segments such as characters and pictures in the picture display liquid crystal (B section display area 70) can be set to 0N10FF.

Details such as mode setting of the driver IC 301 and IC 302 are omitted, but these are read.

IC301 and 30

CPtJ (ICIOI) side is 1c301 or IC30
When READY = L from at least one of the two, data is not written to the picture display module. This flow is shown in the flowchart of FIG. 33.

Both the liquid crystal dot matrix module and picture display liquid crystal module described above use a backlight.

Examples of such a light include a miniature bulb, LED (light emitting diode), EL (electroluminescence), fluorescent tube (panel), fluorescent lamp, neon tube, and the like. In this example, a cold cathode tube, which is a type of fluorescent lamp, is used.
It was arranged as shown in Figure 4. In the figure, 69 is the A section display area (7-day product panel), 74 is a rubber connector, and 75
is a cold cathode tube, and 76 is a printed board. The cold cathode tube 75 has the advantages of being able to freely select the color of the light by selecting the fluorescent substance, generating less heat, and being able to freely select the amount of light used as a backlight and obtain a high output amount of light. be. In this embodiment, the backlight can be turned on and off freely.

Next, interrupts in this display control will be explained. This interrupt is used to transfer data between the operation unit CPU and main body CPU (IR2) and display blinking timers (IRl, IR3).
used in This will be explained below with reference to the interrupt flow shown in FIG.

This flow shows data transfer between the operating unit CPU and main body CPU, that is, an interruption of IR2.

First, when the lR2 terminal (pco terminal of IC112) of fcI I1 (8259A) in FIG. 24 changes from "l" to "If", interrupt 2 (In2
) are accepted. The IN'F output of ICIII is ■(
“, which causes an interrupt request to the CPU (ICIO1=8088).
Set INTA low to enable output on the Icl0I interrupt vector data bus. When ICIII receives the second INTA sent from rcioi, it outputs an 8-bit interrupt vector. Icl0I is an 8-bit interrupt vector. The interrupt routine jumps to the address corresponding to the interrupt vector and starts the interrupt routine.

When the interrupt routine (In2) is entered, the flag register is first saved. Next, interrupt IRl.

Grant permission for In2. Although this uses the interrupt IRI and In2 as a timer, the timer value is not affected by the interrupt In2. Data (commands) sent from the main unit must be stored in the memory within the operation unit.

FIG. 36 shows a part of the address map of the memory that stores the received data. In the figure, memory (RA
M) Area 68000H to 69FFF) (68 in
An area is provided from 500H to 686 FFH as a buffer BF (command buffer sent from the main body side).

This buffer BF has an area of 512 hides and one command has 8 bits, so it can store 512 commands.

The received commands are stored in the buffer BF starting from the lowest address. The buffer counter consists of 2 bytes, 68710H, 68711H'
, m are arranged, and the last used address of buffer BF +1 is the content of the buffer counter. That is, as shown in FIG. 37 as an enlarged view of the address map of the buffer BF portion in FIG. 36, the value of the buffer counter is 60.
000H+8610H=68610H. BF in the diagram
u indicates a used buffer and BFuu indicates an unused buffer.

In Figure 35, the data sent from the main unit to the address indicated by the buffer counter (IC112 in Figure 24)
Read PA). Then latch ONL, IC
112 PBO="Hs" is issued. After that, a side-in prohibition instruction is issued, the saved flag register is restored, and a return is made.

The timer is a programmable timer IC110 (8
253) is used. This can be programmed to divide the 2Mtlz clock (duty 50%) sent from the pcLK of the clock generator IC102 (8284A) by n using it as a reference clock, or to output a one-shot pulse of a specified length. .

The clock frequency divided by A by this timer ICll0 is 1c.
106 (HD61830).

Also, the IRI of ICIII (8259A) is 1.
A clock of 25m5 is given, and a clock of 10m5 is given to In2. IRl, In2 is an edge trigger, so IRl every 1.2511Is or 10m5.

An interrupt from In2 will occur. For IRI and In2, a timer counter is provided in the interrupt, for example,
A timer counter is provided in n2, and when the value reaches 30, the area or pattern on the liquid crystal display is made to blink. When 0N10FF switching is performed for this purpose, the area or pattern on the display will last 300ms (10m5X
Flashes every 30).

As is clear from FIG. 24, the aforementioned CPU (ICI
IC102 (8
284A) is used. A 12 MHz crystal oscillator (ceramic oscillator or other clock may be used) is externally connected to this clock shake IC 102. Since the frequency of this clock shifter rc102 is internally divided by 1/3, 4 MHz is given to the IC 101 (CPL18088) as CLK. The system clock is 4Ml1z.

Furthermore, since PCLK of rcI02 is further divided by two, a 2 MHz clock is output from PCLK, and this output is sent to timer ICll0.

Also, when data is transferred between IC106 and ICl0I, the response of IC106 is slow, so one-way circuit O
A WC will be provided. As a result, when IC106 is chip selected, IC102 is selected from the one-way circuit OWC.
is given a pulse. ICIO2 Re to rclol
Give the ady signal. ICl0I is R from IC102
Since the ready signal is received, the timing of RD and WR can be delayed by the ready signal. This allows data to be transferred between the ICl01 and the IC106 in a good manner.

Next, the processing of the code sent from the main unit will be explained. The flowchart in FIG. 38 shows a processing routine for messages sent from the main body.

First, the contents of the beginning (68500H) of the buffer (BF) area shown in FIG. 36 are read.

If the upper 4 bits of the read content are all 0, it is processed as data, otherwise it is processed as a command.

In the case of a command, as shown in Figures 39, 40, and 41, the upper 4 bits determine the N area (N
), NS1 area (NSI), NS2 area (NS2), NS3 area (NS3).

NS4 area (NS4) (Figure 39), N1NS] −
1-Ns 2 +NS 3 +NS 4 area (NS
), NS 1 + NS 2 + NS 3 + NS 4 area (N6) (Fig. 40), and picture display area (NP
) (Figure 41). The lower 4 bits indicate the display code of each area. The portions marked with bookmarks in FIGS. 39, 40, and 41 change depending on each mode.

In the case of data, the upper 4 bits are all 0, as shown in FIG. The lower 4 bits indicate the numerical value in binary.

As shown in Figure 43, the data code is located after the command code, and the data code is also 1 digit, 2 digit,
The digits, 3 digits, etc. are positioned like this. In this case, if the displayed numerical value is 3 digits, there are three data codes, and if the displayed numerical value is 2 digits, there are two data codes.

The numerical values of the data differ depending on each mode, and the numerical values of C and d in the figure differ depending on each mode, and the commands in the C and d parts in the figure do not have numerical data.

To give an example of such a code processing, in the case of FIG. 13, the N area (N) contains the numerical value "too".The code processing begins with the N area code E211.
is processed, then the data codes are OOH, OOH,
OIH occurs and the value 100 is displayed as shown in FIG.

In the case of FIG. 14, since there is no numerical value in the N area, there are only commands, and only the command code E3H is processed.

In the case of Figure 17, N+NS 1 +NS 2 +NS
Since the entire area of 3 + NS 4 is used, the command code is 71H and there is no data code.

After the command processing and data processing are completed as described above, the contents of the buffer (BF) area are shifted by 1 byte. That is, the buffer counter is decremented by 1.

In this case, if a message is still contained in the buffer (BF) area, processing of that code is started. Furthermore, when the buffer (BF) area becomes empty, the processing routine returns.

Next, in command processing, the N area (
N) As an example, the case where a command code E4H is received will be explained. Since the N area (N) is a 48x256 dot area, 48x256 bit display data must be set in the external RAM of the IC107 (HO21830).

Now, if you receive the code E4H, the displayed data will be:
As shown in FIG. 44, the data in the data file starting from 31000H is transferred to VRAM. This transfer state is shown in Figure 45 (111, fbl, (C1゜(d
This is done along with the conversion shown in l. In the figure, VR
AM indicates a part of the RAM area from 6900QH to 697FFH. This VRAM is 64 as shown in Fig. 45fbl.
However, since the liquid crystal used in this example has a duty of 1/32, the dot configuration becomes 32x512 type on the software as shown in Fig. 45 (fc), so the VRAM data is Convert it to 32x512 type and set it in 1c107, which is the external RAM of IC106.

In FIG. 44 (δ), X indicates the number of data in the X direction (48 in this case), and y indicates the number of data in the X direction (256 in this case). Therefore, (x, y) = (48
, 256) = (30H, FFH], and Fig. 44 (
The first two hides (3100014, 31001H) of the data file starting from 1.31000H in 'bl
) indicates file size information, that is, the number of data in the X direction (30H in the second equation) and the number of data in the X direction (FFH in the above equation). Therefore, Fig. 44 (bl
31002H to 31601H are displayed data. Since 8 bits are set in 1 bar, it is only necessary to decrement by 8 each time 1 byte of display data starting from 31002H is set.

As shown in FIG. 44 (5), after setting the X1 line to 256 bits (=32 bits I'l-), the X2 line is set to 2
56 bits (=32 bytes), x3----x32
The line is sequentially 256 bits (-32 bytes) is
69000H to 697FFH as shown in Figure 5(a)
Set to VRAM of.

” This V RAM is 64:<2.
56 inch, the liquid crystal used in this example has a duty of 1/32, so its dot configuration is 32 x 512 inch in software, so the VRAM
The data is converted to 32x512 type data and then set in ICl07, which is an external RAM of IC106.

As a result of the above, an image corresponding to the command code E4H is displayed in the N area (N) of FIG. 39.

In addition, data processing is similar to the command processing described above.
By setting data to AM, data is set to external RAM (ICI 07) of IC106,
The corresponding image will then be displayed.

(Effect) The present invention is as described above, and according to the control device according to the present invention, when a guidance key is pressed during mode setting, and when the guidance key is pressed again during execution of guidance display for that mode, Since the display contents are returned to the final display during mode setting, it is possible to return to the mode setting mode before the guidance display ends.
