Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone having an opening / closing mechanism. 2. Description of the Related Art Foldable portable telephone devices are available on the market, in which a blinking LED blinks to indicate a call incoming or a message incoming. By the notification of the LED, it is possible to visually notify the incoming call or the like without ringing a ringing tone that causes trouble to the surrounding people and without using a vibrator function that does not know the incoming call if the user does not have it. [0003] However, since the power source of the portable telephone device is a battery, power saving is an important issue, and unnecessary turning on of an LED is not preferable. SUMMARY OF THE INVENTION A portable telephone device of the present invention has been made in view of the above points, and has a display unit for displaying a notification such as an incoming call and an opening / closing mechanism for opening and closing the display unit. A cover, an opening / closing detection unit that detects opening / closing of the cover, a lighting unit that is provided at a position where the cover is exposed in a state where the display unit is closed, and that lights or flashes the notification, and When the open / close detection unit detects that the display unit is closed, the notification by the lighting unit is allowed, and the display unit is opened by the cover when the notification is performed by the lighting unit. A control unit for prohibiting the notification by the lighting unit when the opening / closing detection unit detects the detection. Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a main part of the embodiment. The telephone device of the present embodiment is a CDMA mobile phone that uses a plurality of carriers of the same frequency in the same cell. A communication unit (1) transmits a signal from a baseband unit (3) to be described later to a base station via an antenna (2), and transmits a signal from a base station via the antenna (2). Or receive. [0007] (3) is a baseband unit, which is CDMA
It has a processing circuit (31) and an audio codec (32).
The CDMA processing circuit (31) performs code division multiple access, scrambling, error control, and timing detection. The audio codec (32) compresses (encodes) and decompresses (decodes) audio.
Or a conversion between analog and digital, and changes the reception volume and microphone sensitivity by an internal amplifier circuit (not shown). Reference numeral (4) denotes a speaker which is used for a telephone call to the ear, and converts the electric signal of the baseband section (3) amplified by the amplifier circuit (5) into sound. (6) is a microphone used for telephone conversation, which converts voice into an electric signal. (7) is an amplifying circuit, which amplifies the output of the microphone (6) and outputs it to the baseband unit (3).
(8) is a speaker for listening to a call to surrounding people, and is arranged on the back of the surface on which the ear speaker (4) is arranged. The speaker (8) converts the electric signal of the baseband section (3) amplified by the amplifier circuit (9) into sound. The speaker (8) sounds an incoming call notification. A switching circuit (10) turns on / off the connection between each of the three amplifier circuits (5), (7) and (9) and the baseband section (3) under the control of a control circuit (11) described later. O
FF. Note that these three amplifier circuits (5) and (7)
In (9), the gain is fixed, and the receiving volume and microphone sensitivity cannot be changed. The voice codec (32) of the baseband unit (3) changes the reception volume and the microphone sensitivity under the control of the control circuit (11). Reference numeral (11) denotes a control circuit composed of a microprocessor. The ROM (1) stores an operation program.
Each part is controlled based on 2). (13) is a RAM for storing information necessary for the operation of the control circuit (11).
(14) is a liquid crystal display unit for displaying notification icons such as telephone numbers and incoming calls. (15) is a vibrator, which generates vibration at the time of an incoming call under the control of the control circuit (11). An input unit (16) is a numeric keypad (161) for inputting a telephone number and the like, a SEND key (162) for starting a call and starting a call, and an END for operating a call end and the like. It has a key (163). (17) is L
This is a lighting section made up of an ED, and notifies an incoming call or the like. The portable telephone device of this embodiment has a hinge (19) as shown in FIGS. A receiving unit (20) provided with a speaker (4) and a display unit (14)
Then, the transmission section (21) provided with the microphone (6) and the numeric keypad (161) is opened and closed by the hinge (19).
The open / closed state of the hinge (19) is detected by the open / close detection unit (18) and output to the control circuit (11). Open / close detector (1
8) has a switch (not shown) pressed by a convex portion (not shown) provided on the earpiece (20) when the hinge is closed. In the closed state, the display unit (14) cannot be seen by the user, and indicates that there is an incoming call, that a text message or a voice message has been received, that the terminal is out of the area of the base station, and the like. It cannot be notified in section (14). For this purpose, as shown in FIG. 3, a lighting section (17) is provided at a position where the lighting section (17) is exposed in a closed state, and the above-described notification is performed. The two or more types of notification are distinguished by a change in emission color or lighting time. The lighting of the lighting section (17) is controlled by a control circuit (1).
This is performed by 1). This control circuit (11)
As shown in the flowchart of (1), when the hinge (19) is open (Y in S1), the notification of the lighting section (17) is prohibited (S2). When the hinge (19) is closed (S1
N), the notification of the lighting section (17) is permitted (S3). For example, when there is an incoming call, the hinge (1
With 9) closed, the display section (14) and the lighting section (17) notify the incoming call, and the speaker (8) sounds. When the hinge (19) is opened, only the lighting section (17) stops reporting the incoming call. Then, the call key (162)
Is operated, the display unit (14) and the speaker (8) stop reporting the incoming call, and the call is made. In the related art, the end of the notification of the lighting unit (17) is performed simultaneously with the end of the display unit (14). However, the present invention is performed earlier than the end of the display unit (14). can do.
When the hinge is opened, the user can know the notification on the display unit. If there is an incoming call (call waiting, call waiting) from a third party during a call or if a text message is received during a call, a hinge (19)
Since the is open, the lighting unit (17) does not perform the notification. As a result, the lighting section (1) that the user does not see
7) Power can be saved. If the user closes the hinge (19) after the call, the lighting section (17)
Is notified, and the reception of the text message can be notified. Although the display unit of this embodiment is opened and closed by a rotary hinge, the present invention is not limited to the rotary system. For example, a slide type open / close mechanism can be applied. Although the cover for closing the display unit of this embodiment is a transmission unit having a microphone and a numeric keypad, a microphone and a numeric keypad are not required to close the display unit. The present invention can also be applied to the present invention. As described above, the present invention focuses on the fact that in a portable telephone device having an openable and closable display unit, if the display unit becomes visible, it is not necessary to provide an overlapping notification by a lighting unit. The purpose of the present invention is to save power, which is the fate of the mobile phone device, by stopping the duplicate notification by the lighting unit.
