The display device 34 is a liquid crystal display device having a backlight therein, and displays various character information for indicating the state of a call and communication and prompting the user for various operations. Further, the backlight uses an LED as a light source, and light emitted from the LED spreads to a predetermined portion of the display 34 by a light guide plate. In this example, the backlight is an LED that emits light of one type of emission color. However, as with the base unit BASE, two types of LEDs with different emission colors are used to respond to the incoming public line. It may be configured to control which of these LEDs emit light. In this case, information on the public line that has received an incoming call is transmitted from the base unit BASE.

  The MMI control unit 33 a also controls the operations of the transmission microphone 36, the reception speaker 37, and the rear speaker 38 based on the information input through the key 35.

  The storage device 39 is a non-volatile RAM, for example, and is a recording medium that stores a program for controlling the operation of the slave unit HSk. In addition, there may be a storage device used for buffering audio data and communication data.

  Next, the operation of the base unit BASE for incoming calls from the public lines L1 and L2 in the telephone system 1 having the above configuration will be described with reference to the flowchart of FIG.

  The line control units 18a and 20a of the base unit BASE monitor incoming calls from the public lines L1 and L2, respectively. However, the public line L1 is not received in S1, and the public line L2 is not received in S2. In this case, the base unit BASE enters the “standby state” of (1). In this state, the backlight of the display unit 16 of the base unit BASE is turned off, and the ringing tone is not sounded.

  Next, when the public line L1 has not arrived at S1 and the public line L2 has arrived at S2, the base unit BASE enters the “public line L2 incoming state” of (2). Since this state is a state in which a call is received only from the public line L2, an LED indicating that the public line L2 has arrived, that is, an LED that emits red light, is used for the backlight of the display 16. The display 16 is lit in red, and during that time, the ringing tone sounds with the tone for the public line L2.

  Next, when the public line L1 is received at S1 and the public line L2 is not received at S3, the base unit BASE is in the “public line L1 incoming state” of (3). Since this state is a state in which a call is received only from the public line L1, an LED indicating that the public line L1 has arrived, that is, an LED that emits green light, is used for the backlight of the display 16. The display 16 is lit in green, and during that time, the ringing tone sounds with the tone for the public line L1.

  Next, when the public line L1 is received at S1 and the public line L2 is received at S3, the base unit BASE is in the “public line L1 / L2 incoming state” of (4). Since this state is a state in which calls are simultaneously received from the public line L1 and the public line L2, both the LED that emits green light and the LED that emits red light are used as the backlight of the display 16. The display 16 is lit in each color alternately at regular intervals. In the meantime, the ringing tone is also alternately sounded with the tone for the public lines L1 and L2 in accordance with the alternate lighting.

  As described above, according to the base unit BASE according to the present embodiment, the display 16 is lit in the color corresponding to the public line regardless of which of the public lines L1 and L2 is received. Therefore, even if the user is far away from the base unit BASE, the user can easily visually determine which public line has received the call.

  Further, since the display 16 changes the color of the backlight in order to notify which public line has received an incoming call, it is possible to easily distinguish the lighting color in the notification. Further, since the display device 16 also serves as a display unit for displaying characters, it is suitable for miniaturization of the parent device.

  The display 16 lights in green when an incoming call is received from the public line L1, but this color is also a familiar color since it is also the lighting color of the display 16 other than when receiving an incoming call. On the other hand, since it is not lit in red except when an incoming call is received, red is a color that is not usually used. Therefore, it is easy for the user to remember that the green color corresponds to an incoming call from the public line L1, and the red color corresponds to an incoming call from the public line L2. it can.

  In addition, the display 16 is provided with a backlight of three or more colors such as the first color, the second color, the third color, and so on. When an incoming call is received, it may be lit in a color other than the first color. In this way, it lights in the first color except when an incoming call is received, and lights in other colors when an incoming call is received, so that the user visually determines that there is an incoming call from one of the public lines. It is easy to recognize that it should be subsequently determined which public line the incoming call is from. In addition, a display state change such as the presence or absence of blinking may be added to distinguish the lighting of both.

  Further, as described above, the display 16 is alternately lit in each color when receiving from the public lines L1 and L2 at the same time. In this way, when a call is received from a plurality of public lines at the same time, if the light corresponding to each of the received public lines is turned on instead of the corresponding color, the user sees the light that is turned on instead of the It is possible to recognize that there is an incoming call and which line the incoming call is from. In addition, a display state change such as the presence or absence of blinking may be added to distinguish the lighting of both.

  The telephone system 1 according to the present embodiment includes a parent device BASE and a child device HSk combined with the parent device BASE. In a system in which the slave unit is picked up by looking at the reception status at the master unit, the position where the slave unit is picked up is generally separated from the master unit to some extent, so for users using the slave unit HSk When the indicator 16 of the base unit BASE is turned on, it is easier to determine from which public line the incoming call is received, and the response operation at the handset HSk becomes smoother. The base unit BASE of the present embodiment is a telephone that enables such discrimination. In addition, since the slave unit is a small device, even if there is a restriction on the configuration in which the display unit of the slave unit is turned on in the same manner as the master unit, the display unit on the master unit side is set for each public line. It is convenient if it corresponds to lighting with the corresponding color.

  Further, in the present embodiment, the lighting color is changed using the display device 16, but the lighting color may be changed in such a configuration that the entire telephone is turned on. In this case, it becomes clear which public line has received a call from a distant user.

  In addition, the incoming call notification method for the base unit BASE and the slave unit HSk described above is realized by executing a program including a process corresponding to each step in FIG. 1 by a computer provided in the base unit BASE and the slave unit HSk. it can. Thereby, the incoming call notification method for the base unit BASE and the handset HSk can be made versatile.

  The program can be provided to the user by storing it in a computer-readable recording medium. Thereby, the said program can be provided easily. This recording medium may be a built-in medium built in the computer main body like the storage devices 19 and 39 described in FIG. 3, or a removable medium configured to be separable from the computer main body. Also good. Examples of the built-in medium include ROM; rewritable nonvolatile memory such as flash memory; and hard disk. In addition, as the removable media, optical recording media such as CD-ROM and DVD; magneto-optical recording media such as MO; magnetic recording media such as floppy (registered trademark) disk, cassette tape, and removable hard disk; memory cards and the like And a medium having a built-in rewritable nonvolatile memory such as a medium having a built-in ROM such as a ROM cassette.

  The program may be configured to be executed by CPU access, or after reading the program stored in the recording medium and transferring the read program to the program storage area of the built-in medium, the program on the built-in medium May be executed by CPU access. In addition, the program is not limited to be sold in a state where it is stored in a computer-readable recording medium, and is sold in a format that is transferred to a user's computer via a communication network such as the Internet.
