Description

  The present invention relates to a communication apparatus capable of registering an initial screen.

  Since the mobile phone device cannot receive a call when the power is turned off, the power is usually kept on. For this reason, the initial screen displays a screen that does not interfere with others, such as an incoming standby screen or a clock screen.

  This display method was also applied to a folding cellular phone device. However, since the foldable mobile phone device is normally closed, it is not necessary to care for others to see the initial screen as the straight phone device that is not foldable. In view of the above, there has been a demand for an effective display method of an initial screen in a folding cellular phone device.

  The communication device of the present invention has been made in view of such a point, and the first housing having the display unit and the second housing can be opened and closed via the hinge portion, and are exposed when the device is closed. If the non-display key is pressed when the device is opened, the initial screen set at the time of shipment from the factory is displayed on the display unit, and the device is opened. When the non-display key is not pressed, the initial screen set by the user is displayed on the display unit.

  In a foldable mobile phone device that does not need to care for others to see the initial screen as in a straight phone device that is not foldable, it is possible to display what the user desires on the initial screen.

  Hereinafter, specific examples of the present invention will be described in detail with reference to examples and drawings. However, the embodiments shown below exemplify a communication device for embodying the technical idea of the present invention, and are not intended to identify the present invention as the communication device.

  (3) is a baseband unit, which includes a CDMA processing circuit (31) and a voice codec (32). The CDMA processing circuit (31) performs code division multiple access, scrambling, error control, and timing detection. The voice codec (32) compresses (encodes) / decompresses (decodes) the voice, performs analog / digital conversion, and changes the reception volume and microphone sensitivity by an internal amplifier circuit (not shown). . (4) is a speaker that is used for a telephone call that is applied to the ear, and converts the electric signal of the baseband unit (3) amplified by the amplifier circuit (5) into sound. (6) is a microphone used for a telephone call, which converts voice into an electrical signal. (7) is an amplifier circuit which amplifies the output of the microphone (6) and outputs it to the baseband unit (3). (8) is a speaker for letting people talk about the call, and is provided on the back of the surface on which the ear speaker (4) is provided. This speaker (8) converts the electric signal of the baseband part (3) amplified by the amplifier circuit (9) into sound. The speaker (8) sounds an incoming call notification.

  (10) is a switching circuit, and turns on / off the connection between the three amplifier circuits (5), (7), (9) and the baseband unit (3) under the control of a control circuit (11) described later. Note that these three amplifier circuits (5), (7), and (9) have fixed gains, and the received sound volume and microphone sensitivity cannot be changed. The voice codec (32) of the baseband unit (3) changes the reception volume and microphone sensitivity under the control of the control circuit (11).

  (11) is a control circuit comprising a microprocessor, and controls each part based on a program stored in the ROM (12). Reference numeral (13) denotes a RAM which stores information necessary for operation of the control circuit (11) (initial screen registration information and the like). (14) is a liquid crystal display unit that displays telephone number and display information corresponding to the date. (15) is a vibrator, which generates vibrations when an incoming call is received based on the control of the control circuit (11).

(16) is an input unit, which is a numeric keypad (161) for inputting a telephone number and the like, a call key (162) for operating a call and starting a call, and an end key (for operating a call end) ( 163), a setting key (164) for setting the initial screen, and a non-display key (165) for not displaying the set screen. (17) is an open / close detection unit, which detects the open / close of the foldable apparatus and outputs it to the control circuit (11).
As shown in FIGS. 2 and 3, the foldable mobile phone device of this embodiment includes a hinge (18). The receiver (19) provided with the speaker (4) and the display (14) and the transmitter (20) provided with the microphone (6) and the numeric keypad (161) are opened and closed by the hinge (18). . The open / close state of the hinge (18) is detected by the open / close detection unit (17) and output to the control circuit (11). The open / close detection unit (17) includes a switch (172) that is pressed by a convex portion (171) provided in the earpiece (19) when the hinge (18) is closed. The non-display key (165) is arranged on the side surface of the receiver (19) so that it can be operated even in the closed state.

  Next, main operations of the embodiment will be described. 4 is a flowchart showing the setting operation of the control circuit (11), and FIG. 5 is a flowchart showing the display control operation of the initial screen of the control circuit (11).

  In FIG. 4, when the setting key (164) is pressed (Y in S1), the control circuit (11) displays to request selection of the initial screen (S2). For example, an incoming standby screen / clock screen / calendar screen / schedule screen / mail screen / animation screen / notepad screen / memory dial screen / network data screen are selected.

  When the initial screen is selected (Y in S3), the control circuit (11) displays to request the setting of the display time of the selected screen (S4). For example, if the display time is limited, the input is made with a two-digit number for a few minutes. If the display time is unlimited and the setting is terminated, “99” is input. If a number other than “99” is input (Y in S5, N in S6), the process returns to step S2 to request setting of an initial screen to be displayed after the input time has elapsed. If “99” is input, the setting contents are stored in the RAM (13) (S7).

  In this way, a plurality of screens can be set as the initial screen. For example, “mail screen” in the first step S3, “01” in the first step S5, “schedule screen” in the second step S3, “02” in the second step S5, and “clock” in the third step S3. When “99” is input in the screen “step S5 for the third time, the mail is displayed for 1 minute, the schedule is displayed for 2 minutes, and then the clock is displayed as the initial screen.

  In FIG. 5, the control circuit (11) monitors whether or not the device has changed from a closed state to an open state (S11). Recognition that the device has been opened is performed by detecting that the switch (172) has changed from being pressed by the convex portion (171) to being not pressed.

  When the device is opened (Y in S11), if the non-display key (165) is pressed (Y in S12), it is stored in the initial screen (ROM (12)) set at the time of factory shipment. (Setting screen) is displayed (S13). When the device is opened (Y in S11), if the non-display key (165) is not pressed (N in S12), the initial screen set by the user (stored in the RAM (13) in step S7) Display screen) (S14).

  Thus, the present invention can display a screen set by the user when the apparatus is opened. Thereby, what the user desires can be displayed on the screen that the user first sees. In addition, since the foldable mobile phone device is normally closed, it is not necessary to care for others to see the initial screen as in the case of a straight phone device that is not foldable.

  In addition, since the present invention includes a key that does not display the set initial screen, the user can select the display according to the situation. The operation method may display a screen set when the key is not pressed as in the above-described embodiment. As shown in the flowchart of FIG. 6, the screen set when the key is pressed is displayed. It may be displayed.
