DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the main part of the first embodiment. The foldable mobile phone device of this embodiment is a CDMA foldable mobile phone device that uses a plurality of carriers of the same frequency in the same cell.
[0008]
(1) is a communication unit that transmits a signal from a baseband unit (3), which will be described later, to the base station via the antenna (2), or receives radio waves from the base station via the antenna (2). Or
[0009]
(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). .
[0010]

(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.
[0011]
(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).
[0012]
(11) is a control circuit comprising a microprocessor and controls each part based on a program stored in the program memory (12). (13) is a non-volatile data memory that retains stored contents even when the power is turned off, and stores information necessary for the operation of the control circuit (11). (14) is a liquid crystal display unit that displays notification icons such as telephone numbers and incoming calls. (15) is a vibrator, which generates vibrations when an incoming call is received based on control of the control circuit (11).
[0013]
Reference numeral (16) denotes an input unit, which is a numeric keypad (161) for inputting a telephone number, a call key (162) for operating a call and a start of a call, and an end key (for operating a call end) 163).
[0014]
As shown in FIGS. 2 and 3, the foldable mobile phone device of this embodiment includes a hinge (18). The earpiece (19) provided with the speaker (4) and the display unit (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.
[0015]
4 and 5 are flowcharts showing main operations of the embodiment. Here, A is a variable (flag) indicating whether or not an input of an ID (password) is requested, and is stored in the nonvolatile data memory (13). The control circuit (11) requests ID input when A = 0, and does not request ID input when A = 1. Initially, ID = 0 (S1).
[0016]
The device of the embodiment has a dial lock function, and this function is set to ON / OFF by a predetermined operation. This setting is stored in the data memory (13).
[0017]
When the power is turned on (S2) and dial (including abbreviated dial) input is started (S3), for example, when the numeric key of the numeric keypad (161) is input once, the control circuit (11) is dialed. The input is interrupted, and it is checked whether or not the dial lock is set to ON (S4). If it is set to ON (Y in S4), the control circuit (11) checks whether or not the variable A is 0 (S5). If it is 0 (Y of S5), the character which requires input of ID will be displayed on a display part (14) (S6). When the ID is correctly input (Y in S7), the variable A is set to 1 (S8). Then, the control circuit (11) restarts the dial input. When the dial is input (Y in S9), the control circuit (11) makes a dial call (S10) and shifts to a call process (S11). If the call is ended by operating the call end key (163) or the like (S12), the variable A is not changed and the process returns to step 3.
[0018]
If the dial lock is not set to ON in step S4 (N in S4), the process proceeds to step S9. If the variable A is not 0 in step S5, the process proceeds to step S9. Thus, when dialing again, it is not necessary to input the ID.
[0019]
As shown in FIG. 5, when the control circuit (11) detects that the hinge (18) is closed during standby by the open / close detection unit (17) (Y in S21, Y in S22), the variable A is returned to 0 ( S32). When the hinge is closed, the mobile phone device is determined not to be used for a while, and the dial is locked. This makes it necessary to input an ID when dialing for the first time after opening the hinge.
[0020]
As described above, the dial lock function of the embodiment is configured such that the ID input request is made only once until the hinge is closed. For this reason, the dial can be transmitted many times with one ID input until the hinge is closed.
[0021]
The present invention can be applied not only to the dial lock function but also to all key lock functions except the power supply. With this as the second embodiment, the main operations are shown in FIG. 5 (same as the first embodiment) and the flowchart of FIG. In FIG. 6, when the power is turned on (S32), the control circuit (11) requests input of an ID (Y in S35). When the ID is input (Y in S36), the variable A is set to 1 (S37). The variable A returns to 0 when the hinge is closed (FIG. 5). Thus, the ID may be input once until the hinge is closed.
[0022]
In the above-described embodiment, the ID input request is controlled by closing the hinge. However, when the hinge is opened, the ID input may be requested only at the first dial input. With this as a third embodiment, the main operation is shown in the flowchart of FIG. In FIG. 7, when the hinge is opened (Y in S41), the control circuit (11) sets the variable A to 0 (S42) and requests the input of ID (Y in S35). When the ID is input (Y in S36), the variable A is set to 1 (S37), and the input of the ID is not requested until the hinge is opened again.
[0023]
Further, the present invention can be applied to a case where the power ON / OFF is interlocked with the opening / closing of the hinge and a case where the power is not interlocked. Further, the key lock function may be controlled based on power ON / OFF other than opening / closing of the hinge.
[0024]
【The invention's effect】
As described above, the key lock function of the present invention allows the key input to be performed many times by one password input until the hinge is closed. Therefore, it is not necessary to input the password every time it is used, for example, when dialing continuously or when dialing after displaying the address book.
