Abstract

PURPOSE:To easily select an idle line wire by acquiring the line wire when the selected line wire is idle, indicating only the acquired line wire by a lamp and indicating the operating state of all line wires by a lamp when the selected line wire is not idle and selecting an idle line wire among all the line wires. CONSTITUTION:When slave sets 41-4m select line wires 31-3m and a line wire is idle, it is acquired and the acquired line wire is indicated by a lamp and other line wire lamps are extinguished. When a line wire is selected and its line wire is not idle, the operating state of all the line wires 31-3m is displayed by lamps for a prescribed time. Then a caller observes the display and selects a line wire and makes a call. Then only the lamp of the acquired line wire is lighted and the other line wire lamps are extinguished. Thus, the selection of idle external line wire is facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a button telephone device having a wireless handset connected to a key telephone main device via a wireless line.

[Prior Art] Conventionally, when a plurality of outside lines are used with a plurality of handsets, a button telephone device has been used. In this case, the handset displays the status of the outside line with a lamp to inform the handset which outside line is free, and the handset looks at the display and selects the outside line that is free to make the call. There is.

[Problems to be Solved by the Invention] However, there are devices that connect the main device and a slave device via a wireless line, and this slave unit takes advantage of the characteristics of the wireless line and is designed to be battery-operated and highly mobile. . For this reason,
There was a problem that if the lamp was displayed all the time, the battery would be wasted, and if the lamp was omitted, it would be impossible to tell which outside line was open or not.

[Means for Solving the Problems] In order to solve such problems, this invention lights up the lamp of the selected outside line if it is empty when an outside line is selected, and lights up the lamp of the selected outside line, and a first lamp control means for transmitting data to turn off an outside line lamp; a second rung control means for displaying a lamp indicating the usage status of all outside lines if the outside line is in use when the outside line is selected;
The third lamp control means turns off all outside line lamps when the wireless line connection between the fIi machine and the handset is terminated.

[Function] The handset selects an outside line for making a call, and if that outside line is empty, it captures that outside line and lights up the lamp on the captured outside line,
Turn off the lamps of other outside lines. When the call on the handset ends, all outside line lamps are turned off. If the selected outside line is not empty, the usage status of all outside lines is displayed with a lamp for a certain period of time. When the caller looks at this display, selects an outside line, and makes a call, only the lamp of the captured outside line lights up, and the other outside line lamps turn off.

[Example] FIG. 1 is a block diagram showing the operation of the present invention. In FIG. 0, when an outside line is selected on the handset, step 103 determines that data is received from the handset, and step 104 determines that the outside line is captured data. I judge that there is.

At this time, if there is an outside line, step 105 determines that there is an outside line, and the processes shown in steps 106 to 109, such as acquiring outside line, transmitting acquired outside line lamp lighting data, transmitting other outside line lamp extinguishing data, and stopping lamp lighting timer, are performed. .

Therefore, in step 107, the lamp of the captured outside line is turned on, and in step 108, the lamps of the other outside lines are turned off.

When the call ends, data representing the end of the call is transmitted by pressing the hang button on the handset or placing the handset on the charging stand, so step 103 determines that data has been received from the handset, and step 104 determines that the outside line has been received. It is determined that the data is not captured data, and
In step 111, it is determined that the charging stand is turned off or the charging stand is set.

Therefore, when it is determined in step 112 that the outside line is being captured, the outside line is released as shown in step 113, and data for turning off all the outside line lamps is transmitted as shown in step 114. Therefore, if a wireless line is not established, all outside line lamps are off.

Even if an outside line is selected, if it is determined in step 105 that the selected outside line is not an empty outside line, it is determined in step 115 whether or not it is a held outside line or an incoming outside line whose lamp is displayed. If this determination is YES, the processes from steps 106 to 109 described above are performed, and only the lamp of the captured outside line is turned on, and the other outside line lamps are turned off. If step 115 is determined as No, step 116
, the status of all outside line lamps is checked and status data for displaying the status on the lamps is transmitted. As a result, all external lamps are displayed as empty or in use. Then, in step 117, a lamp lighting timer is started.

When the status of all external lines is displayed with lamps in step 116,
Since the calling party selects an open line, step 103 determines that the data has been received from the handset, step 104 determines that it is outside line acquisition data, and step 105 determines that it is an open line. Therefore, as described above, steps 106 to 109 are performed, and only the lamp of the captured outside line is turned on, the other outside line lamps are turned off, and the timer started at step 117 is stopped.

Furthermore, when all outside lines are in use, a lamp to that effect is displayed in step 116, but outside line selection is not performed. Therefore, the lamp timer started in step 117 is set to step 1.
After waiting for the determination of lamp timer time-up in Step 18, processing for turning off all the outside line lamps is performed in Step 119.

If there is an incoming call from an outside line, YES is determined in step 100, and it is determined in step 101 whether or not there is a ringing outside line. Then, as shown in step 1-2, the incoming call data is transmitted, and the handset is called by this, but at this time, the handset only displays the incoming call lamp and calls the outside line set in the function settings. ing.

[Effects of the Invention] As explained above, the present invention captures the selected outside line when it is free and displays only the captured outside line as a lamp, and when the selected outside line is not free, displays all the lines. The usage status of outside lines is displayed with a lamp, and an open outside line is selected from among them. In addition, since all outside line lamps are turned off when the wireless line is not in use, it is possible to prevent unnecessary lamp display and wasteful battery consumption.
