FIG. 5 is a block diagram showing an example of a schematic configuration of a receiving-side circuit of wireless device 416.

As shown in FIG. 5, the radio apparatus 416 amplifies the signal received by the antenna 420 to an appropriate size with an amplifier 422, cuts a signal of a certain size or less with a noise filter 424, and then demodulates the signal. Demodulation is performed at 426 to obtain the output of the required signal. Therefore, when a signal (telephone number) from PHS telephone 700 is received, PHS telephone 70
Since the output of 0 is constant, by changing the gain of the amplifier 422, a signal whose received radio wave intensity is equal to or lower than a predetermined threshold can be cut by the noise filter 424. At this time, the intensity of the received radio wave is
And the copier 400 (the wireless device 416 thereof). The intensity of the received radio wave decreases as the positions of the two become farther. For example, if the radio wave transmitted from the PHS telephone 700 at a distance of 1 m reaches the copying machine 400 at an intensity of 10 mW, the electric wave at a distance of 2 m is 1.25 mW (= 10 mW ÷ 2 ³ ). Therefore, if the gain of the amplifier 422 is determined so that the reception radio wave of 1.25 mW or less is cut by the noise filter 424, the radio device 416 receives only the radio wave from the PHS telephone 700 within 2 m. Therefore, copier 400 can receive only radio waves from PHS telephone 700 present near itself, and can detect that PHS telephone 700 has approached.

Since the frequency band used in the portable terminal (here, the frequency band used in the transceiver function of PHS telephone 700) is predetermined, radio device 416 naturally transmits the radio wave of the frequency band. Are configured to be transmitted and received.

In the present embodiment, any of the copiers 400 can be operated integrally with the same key using the existing keys 728 to 740 of the PHS telephone 700 according to certain common rules in advance. To create a code table and store it in the ROM 404 of the copying machine 400.
When the S telephone 700 approaches the copier 400, the code table is automatically copied and transmitted to the PHS telephone 700 so that the existing keys of the PHS telephone 700 can be used as keys on the operation panel 408 of the copier 400. Is configured. The above-mentioned code table shows a command input by a key on the operation panel 408 of the copying machine 400 and a PHS.
A code corresponding to a command input by a key on operation panel 408 of copying machine 400 is assigned to an existing key of PHS telephone 700 according to a predetermined correspondence relationship with an existing key of telephone 700. Things. Therefore, the above code table is the same between copiers having the same code corresponding to the same command input by a key on the operation panel. Conversely, if the code corresponding to the same command is different depending on the maker or model, the code table itself is different, but the correspondence between the command and the key shown in the code table is all common. For this reason, the wider the range of standardization and standardization of the code corresponding to the command, the smaller the number of prepared code tables is.

Since the number of existing keys of PHS telephone 700 is limited, for example, when the number of keys on operation panel 408 of copying machine 400 is large, the keys on operation panel 408 that are frequently used are A code table may be created so that only these keys can be operated from the PHS telephone 700 and stored in the copying machine 400.

FIG. 6 is a diagram showing an example of the code table.

As shown in FIG. 6, the code table includes a code (a code corresponding to a command input by a key on operation panel 408 of copying machine 400) and an existing PHS telephone 700 to which the code is to be output. It is a table which shows the correspondence with a key. According to the example shown in FIG. 6, for example, code “103” corresponding to “3” key of PHS telephone 700 corresponds to a command input by “3” key on operation panel 408 of copier 400, and The code “201” corresponding to the “*” key of the PHS telephone 700 corresponds to the command input by the “start” key on the operation panel 408 of the copying machine 400. Therefore, in this example, when the user presses the “3” key and “*” key of PHS telephone 700, codes “103” and “201” are output, respectively, and “3” and “3” are displayed on operation panel 408 of copying machine 400. You can enter the same command as if you pressed the "" key and the "Start" key. As described above, since the code table directly associates the command (code) itself to be input to copying machine 400 with the existing key of PHS telephone 700, the association is unified (that is, fixed). (Following common rules).
, Regardless of the type and shape, size, display and arrangement of keys on the operation panel 408 of the copier 400, the copier 400 can be shared by the existing keys of the PHS telephone 700. It can be operated by the operation of.

S), proceeding to step S1550, if the code table has not been received from copier 400 (S1540: NO),
It waits until the code table is sent from the copying machine 400. In this case, if the code table is not received within the set time, the process may be immediately terminated.

In step S1550, step S15
The code table received at 40 is stored in a predetermined location in the RAM 706.

Then, in step S1560, the P
A message is displayed on display 722 indicating that copying machine 400 can be operated by HS telephone 700 (referred to as “OA operation mode”). Thus, the user can know that the PHS telephone 700 is ready to operate the copying machine 400.

Then, in step S1570, it is determined whether or not a user's key input for operating copying machine 400 has been made. Here, the user performs an operation for operating the copying machine 400 (for example, setting of the number of copies, start of the copy operation, and the like). If there is a user key input (S1570: YES), the process proceeds to step S1580, and if there is no user key input (S1570: N).
O) Wait until there is a key input by the user. In this case, if there is no key input within the set time, the process may be immediately terminated.

In step S1580, step S15
Based on the code table stored in the RAM 706 at 50, the code corresponding to the key input at step S1570, that is, the code assigned to the key operated on the PHS telephone 700 at step S1570,
The data is transmitted to the copying machine 400 via the wireless device 716.

Then, in step S1590, a process for ending wireless communication with copier 400 (for example,
(Reception of the communication end signal and transmission of the line disconnection signal) are performed, and the wireless communication with the copying machine 400 is completed.

Then, in step S1600, the code table stored in the RAM 706 in step S1550 is cleared to prepare for the next operation of the same or another arbitrary OA device.

Next, referring to FIG. 7 and FIG.
A processing procedure when the copier 400 is operated by the PHS telephone 700 will be specifically described. The operation sequence at this time is as shown in FIG.

Here, a case will be described as an example where user A uses his / her PHS telephone 700a to copy three originals set in copying machine 400a. It is assumed that the code table shown in FIG. 6 is stored in the copying machine 400a.

When user A approaches copying machine 400a with his / her PHS telephone 700a, copying machine 400a
Detects this (S1000: YES), and transmits a calling signal to the PHS telephone 700a by the transceiver function (S1010).

When PHS telephone 700a receives the calling signal (S1500: YES), PHS telephone 700a sounds (or vibrates) a ring tone (S1510).

When the user A responds, the PHS telephone 700a detects this (S1520: YE
S), and transmits a response signal to the copying machine 400a (S153).
0).

When receiving the response signal (S1020: YES), copying machine 400a transmits the code table (see FIG. 6) to PHS telephone 700a (S103).
0).

When PHS telephone 700a receives the code table (S1540: YES), it stores this in the RAM.
706 (S1550), and a message indicating that preparation for operating the copying machine 400a is ready is displayed (S156).
0).

When the user A presses the "3" key and presses the "*" key as a start to cause the copier 400a to perform an operation of copying three originals, the PHS telephone 700a receives the key input. Is detected (S1570),
Based on the received code table, codes “103” and “201” corresponding to the key input are transmitted to copying machine 400a (S1580).

Then, the copying machine 400a receives the code "10
3 "and" 201 "(S1040: YE
S), the code is analyzed to recognize the command (S10).
50), and execute an operation corresponding to the command (S1).
060). In this case, the code "103" is
Since the numeral “3” on the operation panel 408 corresponds to the “10” key on the operation panel 408 of the copier 400a, the code “201” corresponds to the start key on the operation panel 408 of the copier 400a.
The same operation is performed as when the start key is pressed after the “3” numeric key is pressed on the operation panel 408 a. That is, the copying machine 400a copies three sheets of the set document.

Then, the copying machine 400a and the PHS telephone 7
00a, a communication end signal and a line disconnection signal are exchanged to complete wireless communication (S1070, S1590),
At the same time, the PHS telephone 700a further performs a code table clear operation (S1600) to prepare for the next operation of the OA equipment.

Therefore, according to the present embodiment, a code table (see FIG. 6) for associating a command input by a key on operation panel 408 of copier 400 with an existing key of PHS telephone 700 by a code in advance is provided. When the PHS telephone 700 approaches the copying machine 400, the code table is transmitted to the PHS telephone 700, and the existing keys of the PHS telephone 700 are stored on the operation panel 408 of the copying machine 400. As a result, any copier 40 can be used irrespective of manufacturer or model within the range where the above association is unified.
0 can be operated centrally using the existing keys of the PHS telephone 700, so that the convenience of the user can be greatly improved and the erroneous operation can be greatly reduced.

In this embodiment, the PHS telephone 7
Although the case where the copying machine 400 is operated by 00 is described as an example, it is needless to say that the OA device to be operated is not limited to this. Similarly, devices such as the facsimile 300 and the printer 500 can be integrally operated using existing keys of the PHS telephone 700 instead of the attached operation panel.

In this case, if the correspondence between commands and keys in the code table is unified across types of OA equipment, for example, a command instructing the same function is common to both the copying machine and the facsimile. By assigning the same key, some operations can be unified across types of OA devices.

Further, in this embodiment, the PHS telephone 700 is used as the portable terminal on the operating side, but the present invention is not limited to this, and any wireless communication device other than the PHS telephone 700 (wireless communication device) (A device that exchanges information with each other). For example, as an example, P
As a device similar to HS, a PH having the function of PHS
There is a mobile terminal with a built-in S (see FIG. 11).

In this embodiment, OA devices having different code tables (for example, copying machine 400a,
00b, facsimile 300, etc.) on the same PHS phone 700, it is necessary to
Although it is necessary to update the code table stored in the HS telephone 700, the code table is automatically cleared when communication with the OA device is completed (see FIG. 8). It is not limited to.

For example, as another code table updating method, when the OA operation mode is set, the PHS telephone 70
One of the 0 keys has a code table erasing function, and the code table is cleared by a user's key operation. When the code table is received and saved from the OA device, all the codes are automatically overwritten and saved. Method, when receiving the code table from the OA device, compare the received code table with the currently stored code table, do not save the received code table if they match, and if not match A method of overwriting and saving, and a method of transmitting a code table erasure signal together with a communication end signal from the OA device to the PHS telephone 700 when terminating the communication, and clearing the code table by the code table erasure signal may be considered.

(Second Embodiment) The second embodiment is different from the first embodiment in which an OA device is operated by using an existing key of a portable terminal. Is displayed on the display of the mobile terminal, and the OA device is operated using a key in the operation screen displayed on the display of the mobile terminal. That is, in contrast to the first embodiment in which the key arrangement is fixed in order to use the existing keys of the mobile terminal,
In the second embodiment, the type, position, shape, and the like of the key can be freely set by the user so that the user can easily use it.

It has a code table storage unit 806b and an operation screen storage unit 806a that stores a registered operation screen displayed on the touch panel 822. The reference code table corresponds to the currently registered operation screen, as described later.

FIG. 14 shows the touch panel 8 of the PDA 800.
FIG. 14 is a diagram showing an example of an operation screen displayed on a display 22.

This operation screen is a screen for arranging and displaying keys for operating OA equipment (for example, copying machine 400). In the example shown in FIG.
9) 826, start key 828, stop key 83
0, a double-sided key 832, a 2-in-1 key 834, a sort key 836, and an up (▲) / down (▼) key 838 for setting a magnification are displayed. The operation screen displayed on the touch panel 822 can be freely set, including the type, display (including shape and size) and position of the key. The set operation screen is stored and registered in the operation screen storage unit 806c of the RAM 806, and the PDA 800
Is read out and displayed on the touch panel 822 each time it communicates with an OA device (such as the copying machine 400). The initial setting / registration of the operation screen includes, for example, screen setting information (for example, the type and display of a touch key) necessary for setting the operation screen.
Is downloaded from an OA device (such as the copying machine 400) in which the information is stored in advance, and the user edits as necessary (deletion of keys to be displayed, arrangement, change of arrangement or display, etc.), and then the RAM 806. Is stored in the operation screen storage unit 806c. RAM
The operation screen saved and registered in 806, of course,
It can be appropriately changed by the user (change of operation screen). For example, FIG. 15 shows an example in which the arrangement and display of the touch keys are changed. Further, if there is a key missing in the operation screen of the currently registered operation screen for the operation of the communicating OA device, the display of the missing key is automatically acquired as described later, and the operation screen is displayed. Can be added (reset operation screen). The changed or reset operation screen is used instead of the currently registered operation screen.
The new registration data is stored in the operation screen storage unit 806c of M806.

Note that the portable terminal (here, PDA80
The display of 0) is not limited to a touch panel, and any display may be used as long as it has a function of freely displaying keys on a screen and indicating a position on the screen. For example, a tablet, a digitizer, a trackball, a trackpad, a stick, or the like may be used as the pointing device.

In the following, a case where the copying machine 400 is operated by the PDA 800 will be described as an example.

In the present embodiment, a fixed common function is used in advance so that any copier 400 can be unifiedly operated with the same key using the touch keys in the operation screen displayed on the touch panel 822 of the PDA 800. A code table is created according to the rules of
When the PDA 800 approaches the copying machine 400, the code table is automatically copied and the PDA
0, and the touch keys in the operation screen displayed on the touch panel 822 of the PDA 800 can be used as the keys on the operation panel 408 of the copying machine 400. The code table is stored in the operation panel 40 of the copying machine 400.
Command entered by key on PDA8 and PDA800
A code corresponding to a command input by a key on the operation panel 408 of the copying machine 400 is written in the PDA 800 in accordance with a predetermined correspondence relationship with a touch key in an operation screen displayed on the touch panel 822 of the PDA 800.
Are assigned to touch keys in the operation screen displayed on the touch panel 822. Therefore, as in the case of the first embodiment, the code table is the same between copiers having the same code corresponding to the same command input by the key on the operation panel, Conversely, if the code corresponding to the same command is different depending on the maker or model, the code table itself is different, but the correspondence between the command and the key shown in the code table is all common.

FIG. 16 is a diagram showing an example of the code table.

As shown in FIG. 16, this code table is displayed on the touch panel 822 of the PDA 800 to which the code (code corresponding to the command input by the key on the operation panel 408 of the copier 400) and the code should be output. 7 is a table showing a correspondence relationship with touch keys in an operation screen to be operated. According to the example shown in FIG. 16, for example, the code “103” corresponding to the “3” key of the ten keys 826 in the operation screen is displayed on the operation panel 408 of the copying machine 400.
Corresponds to the command input by the above "3" key,
A code “201” corresponding to the start key 828 in the operation screen also corresponds to a command input by a “start” key on the operation panel 408 of the copying machine 400, and a code corresponding to the sort key 836 in the operation screen also. “601” corresponds to a command input by a “sort” key on the operation panel 408 of the copying machine 400. Thus, in this example, the user is
00, a “3” key, a start key 828 and a sort key 83 in the operation screen displayed on the touch panel 822
By pressing 6, the codes "103" and "2"
01 and 601 are output, and the same command as when the “3” key, the “start” key, and the “sort” key are pressed on the operation panel 408 of the copying machine 400 can be input. Thus, the code table is stored in the copying machine 40.
Since the command (code) itself input to 0 and the touch key in the operation screen displayed on the touch panel 822 of the PDA 800 are directly associated with each other, as in the case of the code table shown in FIG. Within the unified range (that is, according to certain common rules), regardless of the manufacturer and model of the copying machine 400, that is, the type, display, and arrangement of keys on the operation panel 408 of the copying machine 400 Regardless of the touch panel 8 of the PDA800
Any of the copiers 400 can be operated by a common operation using the touch keys in the operation screen displayed on the screen 22.

FIG. 17 is a flowchart showing the operation of a copying machine 400 according to the second embodiment. In addition,
The flowchart shown in FIG.
404 is stored as a control program,
This is performed by 402.

First, in step S2000, PDA8
It is determined whether or not 00 is approaching, that is, whether or not 00 is within a predetermined distance. This determination is made by the wireless device 416
The determination is made based on whether the telephone number from the DA 800 is received and a signal corresponding to the telephone number is output. Wireless device 416
If there is a signal output from the PHS phone, that is, if a telephone number is received from the PDA 800,
As in the case of 00, the case is when the PDA 800 approaches the copying machine 400 (when the intensity of the received radio wave exceeds the threshold). When the approach of the PDA 800 is detected (S200
0: YES), to step S2010;
If the approach of 0 is not detected (S2000: N
O), end immediately and wait until the approach of the PDA 800 is detected.

In step S2010, the wireless device 416
A predetermined control signal is transmitted to the PDA 800 through. This control signal is a signal for starting wireless communication between copying machine 400 and PDA 800.

In step S2020, it is determined whether or not a data request signal from PDA 800 has been received through wireless device 416. As will be described later, the data request signal from the PDA 800 requests only the code table, and requests screen setting information (such as the type and display of touch keys) required for initial setting of the operation screen in addition to the code table. There are times when you do. If a data request signal from PDA 800 has been received (S2020: YES), step S
Proceeding to 2030, if the data request signal from the PDA 800 has not been received (S2020: NO), the PDA 8
It waits until a data request signal from 00 is received. In this case, if the data request signal is not received within the set time, the process may be immediately terminated.

In step S2030, the data request signal received in step S2020 is further analyzed to determine whether the data request signal requires only the code table, that is, whether the data request signal requires only the code table. It is determined whether screen setting information is requested in addition to the code table. If the received data request signal requests only the code table (S2030: YES), step S20
Proceeding to S4030, if the received data request signal requests the code table and the screen setting information (S2030: N
O), and proceed to step S2050.

In step S2040, the code table (see FIG. 16) stored in ROM 404 is copied.
After transmitting to the PDA 800 via the wireless device 416, the process proceeds to step S2060.

In step S2050, the ROM 4
04 (see FIG. 16)
After the screen setting information is copied and transmitted to the PDA 800 via the wireless device 416, the process proceeds to step S2060.

In step S2060, the wireless device 416
It is determined whether or not a key display request from PDA 800 has been received, for example, within a set time. The key display request is a request issued when there is a key display that is insufficient on the currently registered operation screen, as described later. P
If the key display request from DA 800 has been received within the set time (S2060: YES), the process proceeds to step S2070, and if the key display request from PDA 800 has not been received within the set time (S2060: NO), immediately. Proceed to step S2080.

In step S2070, the process proceeds to step S2070 from the screen setting information stored in ROM 404.
The key display requested in the key display request received at 60 is copied, and the PDA 8 is copied through the wireless device 416.
After transmitting to 00, the process proceeds to step S2080.

At step S2080, the wireless device 416
It is determined whether or not a code has been received from PDA 800 through. If the code has been received from the PDA 800 (S2080: YES), the process proceeds to step S2090,
If the code from the PDA 800 has not been received (S
2080: NO), and waits until a code from PDA 800 is received. In this case, when the code is not received within the set time, it may be determined that the user does not intend to operate the copying machine 400, and the process may be immediately terminated.

In step S2090, step S20
The code received at 80 is analyzed to recognize the corresponding command.

In step S2100, an operation corresponding to the command recognized in step S2090 is executed.

Then, in step S2110, the P
Processing for terminating wireless communication with the DA 800 (for example, transmission of a communication end signal and reception of a line disconnection signal) is performed, and wireless communication with the PDA 800 is completed.

FIGS. 18 and 19 are flowcharts showing the operation of the PDA 800 according to the second embodiment. The flowcharts shown in FIGS. 18 and 19 are stored as a control program in the ROM 804 of the PDA 800, and are executed by the CPU 802.

First, in step S 2500, it is determined whether a control signal from copier 400 has been received through wireless device 816. If a control signal from copier 400 has been received (S2500: YES), step S251 is performed.
If the control signal from the copying machine 400 has not been received (S2500: NO), the process immediately ends, and waits until a control signal from the copying machine 400 is received.

In step S2510, it is determined whether or not the operation screen displayed on touch panel 822 has already been registered, that is, operation screen storage unit 8 of RAM 806.
06c is determined. If the operation screen has already been registered (S2510: YES), the process proceeds to step S2560, and if the operation screen has not been registered yet (S2510: NO), step S2520.
Proceed to.

In step S2520, the copier 400 is set via the wireless device 816 to initialize the operation screen.
Request for screen setting information (such as the type and display of touch keys) necessary for the initial setting of the operation screen in addition to the code table.

Then, in step S2530, it is determined whether or not the code table and the screen setting information transmitted from copying machine 400 have been received through wireless device 816. If the code table and the screen setting information have been received from copying machine 400 (S2530: YES), the process proceeds to step S2540, and if the code table and the screen setting information have not been received from copying machine 400 (S2530: NO), the copying is performed. Machine 4
It waits until a code table and screen setting information are sent from 00. In this case, if the code table and the screen setting information are not received within the set time, the process may be immediately terminated.

In step S2540, step S25
30 is stored in the code table storage unit 806a of the RAM 806, and the reference code table storage unit 80 of the RAM 806 is separately registered as a reference code table.
6b.

In step S2550, an operation screen (see FIG. 14) is set based on the screen setting information received in step S2530, and is newly stored and registered in the operation screen storage unit 806c of the RAM 806. Proceed to S2660. When setting the operation screen,
As described above, the user can appropriately edit (delete the displayed key, arrange, change the arrangement or the display, etc.) as necessary. Step S2540 and step S2550 may be performed in the reverse order.

On the other hand, in step S2560, since the operation screen has already been registered, only a code table is requested to copying machine 400 through wireless device 816.

Then, in step S2570, it is determined whether or not the code table (see FIG. 16) transmitted from copying machine 400 has been received via wireless device 816. When the code table is received from the copying machine 400 (S2570: Y
ES), the flow advances to step S2580. If the code table has not been received from the copying machine 400 (S2570: N).
O), and wait until a code table is sent from the copying machine 400. In this case, if the code table is not received within the set time, the process may be immediately terminated.

In step S2580, step S25
The code table received at 70 is stored in the code table storage unit 806a of the RAM 806.

In step S2590, the code table received in step S2570 is compared with the reference code table currently registered, and the reference key currently registered in the touch keys included in the received code table is compared. Whether there are touch keys not included in the code table (that is, not included in the currently registered operation screen), in other words, insufficient touch keys displayed on the currently registered operation screen Check if there is.

Then, in step S2600, it is determined based on the result of the comparison process in step S2590 whether or not the touch keys displayed on the currently registered operation screen are insufficient. If there are insufficient touch keys to be displayed (S2600: YES), step S26
The process proceeds to step S10, and if there is no shortage of touch keys to be displayed (S2600: NO), the process immediately proceeds to step S2660.

In step S2610, step S25
A request is made to the copier 400 via the wireless device 816 to display the missing touch keys recognized in the comparison process at 90.

Then, in step S2620, it is determined whether or not the key display transmitted from copying machine 400 has been received through wireless device 816. If a key display has been received from copying machine 400 (S2620: YES), the process proceeds to step S2630, and if a key display has not been received from copying machine 400 (S2620: NO), copying machine 400
Wait until a key indication is sent from. In this case, if the key display is not received within the set time, the process may be immediately terminated.

In step S2630, step S26
The key display received at 20 is added to the currently registered operation screen, and the operation screen displayed on the touch panel 822 is reset. Even in the case of resetting the operation screen,
The user can appropriately edit (delete, arrange, change arrangement or display of displayed keys, etc.) as needed.

In step S2640, the currently registered operation screen is deleted, and step S2630 is executed.
The operation screen re-set in the step is saved in the operation screen storage unit 806c of the RAM 806, and the registered operation screen is updated with new contents.

In step S2650, the currently registered reference code table is deleted in order to associate the reference code table with the updated operation screen.
The code table received at 70 is used as a new reference code table.
After storing in the reference code table storage unit 806b of the AM 806 and updating the registered reference code table to the new contents, step S
Proceed to 2660.

At step S2660, the currently registered operation screen is displayed on touch panel 822. This allows the user to know that the PDA 800 is ready to operate the copying machine 400.

Then, in step S2670, it is determined whether or not the touch key in the operation screen displayed on touch panel 822 in step S2660 has been lightly touched with a finger, so that a user's key input for operating copying machine 400 has been made. Judge. Here, the user performs an operation for operating the copying machine 400 (for example, setting of the number of copies, start of the copy operation, and the like). If there is a key input by the user (S2670: YES), step S2680
If there is no key input by the user (S2670:
NO), and wait until a user inputs a key. In addition,
In this case, if there is no key input within the set time, the process may be immediately terminated.

In step S2680, step S25
40 or based on the code table stored in the code table storage unit 806a of the RAM 706 in step S2580, a code corresponding to the key input in step S2670, that is, a key operation is performed on the operation screen displayed on the touch panel 822 in step S2670. The code assigned to the key is transmitted to the copier 40 through the wireless device 816.
Send to 0.

Then, in step S2690, processing for ending wireless communication with copier 400 (for example,
(Reception of the communication end signal and transmission of the line disconnection signal) are performed, and the wireless communication with the copying machine 400 is completed.

Then, in step S2700, in step S2550 or step S2580, the RAM 806
The code table stored in the code table storage unit 806a is cleared to prepare for the next operation of the same or any other OA device.

In this embodiment, OA devices having different code tables (for example, copying machine 400a,
00b, facsimile 300, etc.)
In order to operate with the PDA 8
Although it is necessary to update the code table stored at 00, the code table is automatically cleared when communication with the OA device is completed (see FIG. 19), but the method of updating the code table is not limited to this. This is not the same as in the first embodiment. For example, as another method, when an operation screen is displayed on the touch panel 822, one of the keys of the PDA 800 is provided with a code table erasing function, and the code table is cleared by a key operation of the user. A method of automatically overwriting and saving all the code tables when receiving and saving the code table from the device. When the code table is received from the OA device, the received code table is compared with the currently stored code table to find a match. If not, the received code table is not saved, and if they do not match, the code table is overwritten and saved.
0, and the code table is cleared by the code table erase signal.

Further, in the present embodiment, when the key display is insufficient, the missing key display is requested from the OA device (such as the copying machine 400) to be operated. The request destination of the displayed key is not limited to this. For example, various key displays may be stored in the server 200 in advance, and the missing key display may be requested to the server 200 via the network 600 via the OA device of the communication partner. That is, the key display can be requested for any device on the network 600.

In the present embodiment, the operation screen displayed on touch panel 822 of PDA 800 has a structure in which all necessary touch keys are arranged on one screen as shown in FIG. Is not limited to this. For example, the operation screen may be configured by a plurality of hierarchical screens. By tiering the operation screen in this way, more keys can be displayed. Specifically, for example, the copying machine 40
Alternatively, a screen displayed on the touch panel of the operation panel 408 or a printer driver screen stored in the personal computer 100 (both are usually hierarchized) may be downloaded and set as the operation screen.

In each of the above embodiments, the operation of the OA device by the portable terminal is performed by executing a predetermined program describing the above-described processing procedure (see FIGS. 7, 8, 17 to 19) by using the CPU 402, 702, 802. The predetermined program can be provided by a computer-readable recording medium (for example, a floppy (registered trademark) disk or a CD-ROM). In this case, the program recorded on the computer-readable recording medium is usually transferred to and stored on a hard disk. Further, the predetermined program may be provided, for example, as application software that executes the above-described processing independently.
As one function of each of the devices 300, 400, 500, 700, 800, these devices 300, 400, 500, 70
