DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Use The present invention relates to a telephone device having a master unit and a slave unit.

(B) Conventional technology Conventionally, for example, in a cordless telephone device disclosed in Japanese Utility Model Application Publication No. A plurality of display lamps are provided on the master unit and the slave unit so as to enable an extension call between the units and to identify such a plurality of types of call modes.

(C) Problems to be Solved by the Invention By the way, in the cordless telephone apparatus, the individual display lamps show a call display of the base unit or the handset, an extension call display, an incoming call display, a base unit or a handset. Display of calls from
Functions such as hold display are assigned. Thus, when trying to display a predetermined mode by each display lamp alone, it is necessary to recognize what the display lamp represents, and intuitively know what mode is currently in operation. I couldn't do that.

(D) Means for Solving the Problems The present invention has a master unit connected to a telephone line and a slave unit connected to the master unit's telephone line via the master unit. Or, in a telephone device capable of making an external call with a slave unit and making an internal call between the master unit and the slave unit, an external line display body, a master unit display body, and a slave unit display body are arranged in a triangular relationship. A display device in which one or more intermediate display bodies are arranged between the display bodies, and at least, an outside line and a base unit, an outside line and a child unit
And a control circuit for controlling the display of the respective display bodies corresponding to them and the intermediate display body located between these display bodies at the time of calling or talking between the master unit and the slave unit. is there.

(E) Function The present invention is configured as described above, and depends on which of the triangular display lines of the display device is lit or blinking, the outside line and the parent device, the outside line and the child device, or the like. Alternatively, a call or a call between the parent device and the child device can be known.

Embodiments of the present invention will be described below with reference to the drawings.

(13) is a display device for displaying the status of the master unit (1) and the slave unit (2), and is fixed to a cabinet (not shown) of the master unit (1). As shown in FIG. 3, the display device (13) is a transparent panel (14) on which pictures representing the outside line, the master unit, and the slave unit are printed, and is disposed below and between the pictures. It consists of six LEDs (15) (16) (17) (18) (19) (20). (21) is a control circuit for controlling the entire master unit (20). FIG. 2 is a diagram showing the configuration of the slave unit (2), and (22) is a receiving circuit for receiving a signal from the master unit (1), and the received signal is amplified by a receiving speaker (23). . (24) is a transmission circuit for transmitting a signal from the slave unit (2) to the master unit (1), and an output signal of a microphone for transmission (25);
An output signal from the control circuit (26) is supplied. The control circuit (26) transmits a control signal and a dial signal to the master unit (1) based on a key signal from a keyboard (27) composed of a numeric keypad, a call key, a disconnect key, an extension key, a hold key, and the like. Control to send.

 Next, the operation in the above configuration will be described.

First, the control circuit (21) of the base unit (1) controls the network circuit (5) by off-hook of the handset (6) to connect the line with the handset (6), and based on the operation of the keyboard (11). To control the dial circuit (9) to perform dial transmission. At this time, the control circuit (21) operates the LEDs (19), (20), and (15) of the display device (13).
Is scanned and blinked in the direction of the arrow in FIG. 4 to indicate that the base station (1) is transmitting a call to an outside line. When dialing is completed (an end signal is generally output from the dial circuit), the control circuit (21) sets the LED as shown in FIG.
(19) Lights (20) and (15) to indicate that the outside line and base unit (1) are talking.

Next, the control circuit (21) of the base unit (1) connects the reception circuit (3) and the transmission circuit (4) to the telephone line (L) upon detecting a call request signal from the handset (2). Then, control is performed such that dial transmission is performed based on a dial signal from the handset (2) (by operating the keyboard (27) of the handset (2)). At this time, the control circuit (21)
LEDs (17), (16), and (15) are scanned and blinked in the direction of the arrow in FIG. 6 to indicate that the slave unit (2) is transmitting to an outside line. When the dialing is completed, the control circuit (21) turns on the LEDs (17), (16) and (15) as shown in FIG. 7 to indicate that the outside line and the slave unit (2) are talking.

Next, the control circuit (21), which has detected an incoming call from an outside line,
Driving the speaker (12) and transmitting an incoming call notification signal to the slave unit (2), and the LEDs (15) and (16) of the display device (13)
(17) (19) and (20) are scanned and blinked in the direction of the arrow in FIG. 8 to indicate an incoming call. In this state, the handset (6)
When the off-hook is detected, the handset (6) is connected to the telephone line (L), and the display shown in FIG. 5 is displayed. When a call request signal is detected by operating the call key of the handset (2), the receiver (3), the transmitter (4) and the telephone line (L) are connected, and the display shown in FIG. do.

Next, the control circuit (21), which detects the operation of the hold key of the base unit (1) during a call between the outside line and the base unit (1), operates the hold circuit (7).
To play a held melody on the telephone line (L). In this hold state, the control circuit (21) keeps the LEDs (15) and (19) of the display device (13) lit as shown in FIG.
Flashes (20). When the hold is released, the operation of the hold circuit (7) is stopped, and the display returns to the display of FIG. The control circuit (21) which operates the hold key of the slave unit (2) during a call between the outside line and the slave unit (2) and detects the hold signal from the slave unit (2) as shown in FIG. With the LEDs (15) and (17) on the display (13) lit,
Flashes (16). When the hold release signal from the slave unit (2) is detected, the operation of the hold circuit (7) is stopped, and the display returns to the display of FIG.

Next, when the handset (6) is off-hook and the extension key of the master unit (1) is operated, the control circuit (21) sends a calling signal to the slave unit (2). In this state, the control circuit (21) operates the LEDs (19), (18), (1) of the display circuit (13).
7) is scanned and blinked in the direction of the arrow in FIG. 11 to indicate that the calling is being performed. The control circuit (21) which has detected the response signal of the handset (2) to this call connects the handset (6) to the receiver (3) and the transmitter (4), and in this state, the display device (13) LED (17) (18)
(19) is lit as shown in FIG. 12 to indicate that it is an extension call. Further, the control circuit (21) which detects the calling signal by operating the extension key of the slave unit (2) operates the display device (1).
The LEDs (17), (18), and (19) of 3) are scanned and blinked in the direction of the arrow in FIG. 13 to indicate that a call is being made. When it is detected that the handset (6) is off-hook in response to the call signal, the display shown in FIG. 12 is performed.

In the above configuration, the display device is provided only in the parent device (1). However, a display device similar to the above is provided in the child device (2) so that the status from the parent device is detected by the child device (2). You may.

(G) Effects of the invention The invention is configured as described above, and depends on which of the triangular display lines of the display device is lit or blinking, the outside line and the base unit, and the outside line and the child unit. It is possible to intuitively know a call or a call between the handset or the handset and the handset, and to provide a very convenient telephone device.
