Abstract

PURPOSE:To protect secret personal information by recognizing the operation by a specified operator when a terminal equipment is operated and recovering a display. CONSTITUTION:When the value of a work area TIM reaches a preliminarily determined normal value, a dealer performs a start request for switching an off mode lighting all the visible display parts 23 and 24 on a panel surface which are away from a terminal equipment 2. When a key touch exists, the contents of the key detected by key depression processing is compared with the contents of the key depression data which is preliminarily registered in a release key area. When the contents of an area 41 and the key touch coincide, all the visible display parts 23 and 24 are again turned on and a start request that a display on mode is switched is performed. Because this display recovery functions only when the operation by a specified dealer is recognized, the personal information of this specified dealer is made secret and can be protected.

Is a program for monitoring the display and a program for determining whether or not the display off mode is set. When there is a timer interrupt P11 generated from the call control processor 211 at regular intervals, the interrupt control program P12 is activated. The interrupt control program P12 activates various cyclic programs at a predetermined cycle, but in FIG. 4, description of programs not related to the present invention is omitted.

The key monitoring program P21 is activated in a short cycle by the interrupt control program P12, monitors the button scan buffer 223, and detects the pressing of various keys. In step S23, the key monitoring program P21 is an aperiodic program that performs individual processing for each key. Request to start the pressing process. Since the key monitoring program P21 monitors the key operation, the activation cycle needs to be shortened and the load on the call control processor 211 is large. Therefore, it is necessary to reduce the number of execution steps of the key monitoring program P21 as much as possible, and the key pressing process is an aperiodic program that is activated only when the process is necessary. Also in the present invention, in order not to increase the number of execution steps of the key monitoring program P21 as much as possible, only the information indicating that the key is pressed is set in the work area (KEYTCH) in step S22, and other processing is performed by the key monitoring program. The display control program P31 having a longer activation cycle than P21 is used.

In the display control program P31, it is determined in step S32 whether or not the name or the like is currently displayed. If the name or the like is being displayed, the key press of the work area (KEYTCH) set by the key monitoring program P21 is pressed in step S33. It is determined whether or not there is a key touch depending on the presence / absence information, and if there is a key touch, step S
Work area indicating whether or not there is a key touch at 34 (KEYT
CH) is unconditionally cleared, and the work area (TIM) for measuring the time from one key touch to the next key touch is also unconditionally cleared in step S35.

If there is no key touch in step S33, it is determined in step S36 whether or not the dealer is using the terminal device. If it is in use, the same step S34 and step as when there is a key touch are used. The process of S35 is performed. If the terminal device is not used, it is determined in step S37 whether or not the value of the work area (TIM) for measuring the time from one key touch to the next key touch has reached a predetermined value. This value is set in advance as data, but the length of the time from one key touch to the next key touch due to this value is not directly related to the present invention, and therefore description thereof will be omitted.

When the value of the work area (TIM) reaches a predetermined prescribed value, it is determined that the dealer is away from the terminal device, and in step S38, the display off mode for extinguishing all visible display portions of the board is switched to. Request to start the aperiodic program. Work area (TI
If the value of M) is less than the specified value, 1 is added to the value of the work area (TIM) in step S39 to perform time counting.

If the display-off mode is selected in step S32, the work area (K indicating whether or not there is a key touch set by the key monitoring program P21 in step S40).
EYTCH), and if there is a key touch, the contents of the key detected by the key pressing process activated by the key monitoring program P21 in step S41 are pressed in advance in the release key area (SKEY). The contents of the data 41 are compared. An example of the contents of the release data 41 registered in the release key area is shown in the upper right of FIG. In the release key area (SKEY) 41, a plurality of arbitrary key types can be registered. Each time step S41 is started, one key type is stored in a work area (not shown). Now, compare the accumulated number with the contents of the release key area. In this embodiment, the content of the release key area (SKEY) 41 is the button "C".
L ", dial key" 2 ", and button" SL "are registered, and when these three keys are pressed in this order, cancellation of the display off mode is permitted in step S41.
Also, in the contents of the release key area (SKEY) 41, "F
The part "F" indicates that it is not to be compared, and any key up to 4 digits can be registered.

In step S41, the release key area (SK
When the content of EY) 41 and the key touch match, in step S42, the aperiodic program for reigniting all the visible display portions of the board and switching to the display ON mode is requested. If the content of the release key area (SKEY) 41 and the key touch do not match, it is recognized that the release is not possible and step S4 is performed.
Work area indicating whether or not there is a key touch in 3 (KEYTC
H) is cleared and the work area for accumulating the key is also cleared. If there is no key touch in step S40, the current display-off mode is continued, so the processing is integrated with step S43.

With this program, it is possible to achieve a function of detecting that the terminal device is not operated for a certain period of time and turning off the display of the visible display portion, and a function of returning the display only when the operation by the specific dealer is recognized.

FIG. 5 is a flowchart showing an outline of a program for controlling the lamp of the board, a program for switching to the display-off mode and returning to the display mode, and an aperiodic program for performing processing corresponding to various keys. . When the non-periodic program for switching to the display off mode is requested in step S38 of the above-mentioned display control program P31 without the terminal device being operated for a predetermined time, the execution management program P45 displays it on the board of the terminal device. The non-display off program P51 is started.

In the display-off program P51, the display is turned off in the work area (DSPWK) indicating whether the display is turned off in response to a command to turn off the display on the display in step S52 or is turned on when the display is instructed to be displayed on the display. Set
At step S53, the fluorescent indicator 24 is turned off, and then step S
At 54, the operation of the incoming call ringer 29 is stopped. When the key is operated while the display is off and it is confirmed that the operation is performed by a specific dealer, and the display-on program P61 for displaying on the board of the terminal device is started in step S42, the work area (DSPWK) is displayed in step S62. There is a command to turn on the display in, and it is set that the display is on, the fluorescent display 24 is displayed in step S63, and step S64
Then, the ringer 29 is returned, and if there is an incoming call, the ringer rings.

The control of the lamps 23-1 to 23-6 for displaying the state of the line provided on the board of the terminal device 2 is as follows.
In step S72 of the lamp control program P71 which is started by the timer interrupt P11 via the interrupt control program P12, the work area (DSP)
When the display is off (DSKWP = 1), which means that the content of (WK) indicates that there is a command to turn off the display, the lamp control interface is forcibly changed to off-order and controlled in step S73. , All line lamps are extinguished while the display is off.

By the processing described above, it is detected that the terminal device has not been operated for a certain period of time, the display on the visible display portion on the board is turned off, and when there is a key touch, it is determined that it is a key touch by a specific operator. It is possible to protect the personal information of a specific person by recognizing it by operating a predetermined key on the board and restoring the display.

Further, even when the display is off, the pressed key is valid and the normal key pressing program P81 is started. Therefore, in step S82, the work area (DSPW) is displayed.
When the content of K) is on, the process relating to various keys can be executed in step S84. When the display is off, the reception key is set in the release key area (SKEY) in step S83 for analysis in step S41 shown in FIG.

Next, an incoming call while the display is off will be described with reference to FIG. FIG. 6 is a schematic diagram of an aperiodic incoming call control program P91 that is activated by an incoming call detection program (not shown) that is periodically activated by the interrupt control program when an incoming call and an incoming call are released. When an incoming call is detected by the incoming call detection program, step S92
