Abstract

PURPOSE:To display the location of an opposite equipment at an optional position of a map with a program control by arranging display elements of a display device displaying the location of the opposite equipment in matrix by means of an identification signal. CONSTITUTION:Since a number of a light emitting diode corresponding to a station number is stored on a table in advance, the number of the light emitting diode is outputted in response to the station number of opposite party. A signal fed to A-C and D-F is generated in the stage of matrix circuit control signal generation in response to the number. The signal generated in this way is transferred to a matrix drive circuit and a signal to apply latch is outputted. The light emitting diodes 4-12 are arranged on the display device in matrix and limit resistors R1-R6 are provided.

Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a facsimile machine, and more specifically, a recognition means for recognizing a partner machine during transmission or reception, and a display for displaying the location of the partner machine in correspondence with a map. The present invention relates to a facsimile machine having a function and configured to be able to display the location of the other party's machine using a recognition signal based on the recognition means.

[Prior art]

Conventionally, in this type of device, when displaying the location of the other device, one light emitting element was used for each point.
The method used was to place the light-emitting elements only in the minimum necessary positions for display.

Therefore, if the contents of the map change, there is a drawback that the light emitting elements must be rearranged.

Or, even if the content of the map changes, if the number of new locations that you want to display increases, you will need to add a new light-emitting element to the position corresponding to that point, and print on the installation and wiring of the same element. If a printed circuit board is used, a new printed circuit board must be manufactured.
The disadvantage was that it was extremely time consuming.

In addition, conventional devices of this type use pre-printed maps, so when converting to another map, it takes time and effort to replace and attach the map, and the display device also needs time. This had the disadvantage that it took more time and effort because the attachment had to be replaced frequently.

〔the purpose〕

The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional technology, and is configured so that it is possible to eliminate the trouble of re-pasting or replacing the map, or changing the display unit accordingly. The purpose is to provide facsimile equipment.

In order to achieve the above object, the present invention has a structure in which the light emitting elements of the front support part are arranged in a matrix pattern vertically and horizontally, or a liquid crystal display without using a panel printed as a map. A structure using display elements or cathode ray tubes was adopted.

〔Example〕

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

1 to 3 illustrate one embodiment of the present invention.

FIG. 1 shows the appearance of the display section of this embodiment. In the figure, a map 1 printed on a transparent or translucent plastic frame is attached to an outer frame 2. Evening 1
The light emitting elements 3 are arranged in a matrix on the frame 2. By using a matrix circuit (to be described later) and lighting up the light emitting elements at the positions desired to be shown on the map, the operator can visually identify the other machine. You can check the location of

FIG. 2 shows an example of a matrix circuit for making light emitting elements emit light, and here a 3×3 case is shown as an example. To increase or decrease the number of display elements, it is only necessary to increase or decrease the same circuit as shown in the figure. Further, here, a light emitting diode (LED) is used as the light emitting element.

In the same figure, R1-R6 are limiting resistors, and reference numerals 4-12 are T and ED. Each terminal of trenches A-F is configured so that it can be controlled whether it is grounded to the ground that is paired with the 5V supply voltage of this circuit, or whether it is left open. The LED can be turned on. Alternatively, exactly the same effect can be obtained by inputting an appropriate combination of 5V (high voltage) and OV (low voltage) signals to each terminal of A to F' using a drive IC element.

1. For example, if you want to light up LED number 8, press B
, D, and F are grounded, and the other A, , C, and E are left open. If you do this, the current will flow to IJ No. 8 due to R2.
D flows through B to B, and LED No. 8 lights up.

Also, regarding other LBDs, id: D, F' is OV, A,...
Since C becomes 5■, a bias voltage in the reverse direction is applied to each LED except for LED No. 8, and no current flows, so that no light is emitted.

It should be noted that this matrix circuit may also be one without the 5-inch power supply and control resistor.

In this way, L of any point arranged in a matrix
It is possible to cause the ED to emit light.

Next, FIG. 3 is a flowchart showing the operation of a program that generates a control signal for causing the JD described above to emit light.

When the program is started, in step S1, a list (table) 13 is used to select an LED to emit light based on the station number of the other party's device.

Here, the station number of the other machine is the signal C8■ (cold station indication) from the other machine.
(Transmitting Station Indication) Or, if the machine makes an automatic call using an auto dialer, etc., it can be known from the contents of the calling telephone number stored in memory, and a circuit or program for making this determination can be used. Since the flowchart is not related to the essence of the present invention, it will be omitted here.

For example, let us assume that the station number of the other party's machine is 03 (Tokyo), and that the 'I, ED of No. 12 in FIG. 2 is emitted at that time. The table 13 contains in advance the numbers of a plurality of LEDs with station numbers, from which number 12 corresponding to 03 is subtracted. Next, based on number 12, A, -C, D-
A signal to be added to F is created in the matrix circuit control signal generation stage of step S3. LED number 12 is A
, -C, it is found by calculation that it is in the C stage, so A.

B is a high voltage, C is a low voltage, that is, converted to a binary representation (
A,,B,C)-(1,1,0) signal is created. next,
Again, by calculation], we know that LED number 2 is in the F stage of D to F, so we do the same (D, E, F) -
Create a signal of (0, 0, 1).

The signal created in this way is processed in step S4.
When the signal is transferred to the IJ drive circuit (not shown) and a signal for latching is output, LET No. 12 lights up. In addition, in order to turn off the lit LED, use the same program flow to change the shape of the control signal from terminals A to C to (A, B, C) - (1, ], , ], ),
Terminal D-1'i'' is (D, E, F') = (0, 0, 0)
Either turn on the microphone drive circuit or provide a reset circuit and add a reset signal to the circuit. In addition, if LED numbers corresponding to multiple maps are entered in advance in the table 13, when the map is replaced, the T and ED numbers corresponding to the map will be selected, and therefore, other than the light emitting elements The location of the other station can be displayed on the map without any changes to the control mechanism.

This embodiment employs a structure in which the map display elements are arranged in the form of a light beam, and the display is controlled using an appropriate program. ”- can display the position of any other party's aircraft.

Furthermore, by storing the location of the other station with respect to a plurality of maps in the program, it is possible to save the effort of changing the display unit when replacing or replacing maps.

[Second Embodiment] FIGS. 4 to 7 illustrate another embodiment of the present invention. In this embodiment, a structure is adopted in which a map is drawn using a liquid crystal or a cathode ray tube instead of the map 1 printed on the plastic board in FIG.

Figure 4 shows the liquid crystal display (L) used to draw the map.
CD) and its drive circuit.
The figure shows the case of vertical m dots.

In the figure, what is indicated by the reference numeral 14 is an LCD for displaying a map, and the horizontal and vertical columns of this LD'D 14 are one drive circuit 15.1 in the horizontal direction and one in the vertical direction, respectively.
6 to shift registers 17 and 18 for converting horizontal and vertical serial data into parallel data.

Although this circuit is a well-known circuit, its operating principle will be briefly explained below. In addition, there is a well-known technical agency that displays display elements in blocks in order to prevent the displayed liquid crystal elements from looking too thin, but this is not related to the essence of the present invention, so it will be briefly explained here. Therefore, n in the horizontal direction
A method of displaying dots and vertically by sweeping one line at a time will be described.

As shown in Figure 4, each display element of the LCD is commonly connected vertically and horizontally in a matrix.
When viewing the CD from the front, it is assumed that the upper display electrodes are commonly connected to the vertical columns, and the lower display electrodes are commonly connected to the horizontal columns.

For example, if you want to display the element at position C shown in the figure and not display all other elements, data 1 (o
, o, i, o...0) is transferred and placed in shift l-1/register 17. Next, m-bit data (1, 0, 0° . . . 0) is transferred to data 2 and put into the shift register 18. If you do this,
Output terminal A4 of the horizontal and vertical drive circuits 15 and 16
．． A2...A, n and B, B2...13m output a rectangular wave signal as shown in FIG.
, CD The voltage between the electrodes of each display element is the difference between each waveform shown in Fig. 5, but if data 1 and 2 are selected as above, the display element at point C, that is, A3 and A3 in Fig. 5. Only the signal difference of B1 becomes maximum, and all others become small.

FIG. 6 shows the pattern and shows the difference between the signals in FIG. 5. As is clear from the figure, the potential difference h]-r+j (+=1...n, j
==]-1-・, m), A3B+ is the most sensitive. That is, only the display element C in FIG. 4 is displayed darkly, and the others are not displayed or are displayed very faintly. Next, data 1 contains (0,...
・, 0) n-bit data, and data 2 is
After transferring m-bit data of (0, . . . , 0) and performing this in the vertical 2nd, 3rd, . If the sweep is similarly performed at a high speed thereafter, since the response speed of the LCD or human vision is slow to some extent, it appears as if only the point C is displayed all the time. In this way, (1) the CD is driven once.

Next, a program flowchart 1 for drawing a map on the display device of FIG. 4 will be explained.

FIG. 7 shows the flowchart. Map patterns may be stored using an n'lXn bit memory, but in order to save capacity, a method will be described in which the patterns are stored as run lengths and then the map patterns are reproduced.

RT, (7-length) pattern memo 19 KU, m pieces of run-length data in the horizontal direction of the pattern are entered in order up to address address m. Each data contains judgment bits indicating that it is the end of the line in the horizontal direction and the mth final line in the vertical direction, and based on the judgment bits, it is possible to judge whether it is the end of the line or the final line. .

First, in step S1, run length data is converted into normal serial data in an RJ→RAW (run 1/length→serial data) conversion routine. next,
In step S2, it is determined whether the line end has appeared, and if the line end has not appeared, step S1
Return to , and continue converting from RT to RAW at the point where the line end appears. When the line end appears, the serial data obtained in step S1 is converted into n-bit serial data 1.
In step S3, the data is transferred to the circuit shown in FIG. 4 described above. Next, in step S4, if there is black in the n-bit 1-line data mentioned above, the bit of the corresponding vertical line data to be drawn is set to 1, all other bits are set to O, and if there is black , all bits are set to 0 and transferred to the same circuit as data 2. Next, in step S5, it is determined whether such an operation has been completed for lines 1 to m in the vertical direction. If not completed, 81 above
-S5t are repeated for the next line. If the process is completed, the process moves to the next step s6, the read address of the pattern memory is changed to read from the first address, and the same operation is repeated again.

In this way, the map pattern is drawn on the LCD.

As described above, this embodiment uses a liquid crystal display or a cathode ray tube, etc., instead of using a panel printed as a map as in the previous embodiments, so it is possible to save time by storing the map pattern in memory. You can draw a map arbitrarily and display the location of the other party's aircraft.

In the second embodiment, if patterns of a plurality of maps are prepared in the RL pattern memory, a map can be displayed as needed. In order to display the position of the other party's aircraft (1), the position of the other aircraft may be displayed directly on the map using an LCD instead of the above-mentioned LEDs arranged in a matrix.

Regardless of whether an LED or an LCD is used as a display, the position of the own aircraft may be displayed at the same time, or the display may be made to blink, and the latter is generally easier to understand as a display.

Furthermore, the LCD in FIG. 4): The drive circuit may be provided with a buffer and a latch for storing data 1 and data 2.

〔effect〕

As is clear from the above description, according to the present invention, by arranging the display elements that display the location of the other aircraft in a matrix pattern, the other aircraft can be placed at any position on the map under program control. It is now possible to display the location, so even if the printed or LCD map changes, the displayed content can be changed by simply changing part of the program without changing the display components. becomes.

In addition, by displaying maps on an LCD or cathode ray tube, you can select the desired map on the spot, saving you the trouble of replacing or replacing the map or changing the display unit accordingly. This has the effect of allowing for detailed responses.
