Abstract

PROBLEM TO BE SOLVED: To easily execute response holding even in the state of closing respective main bodies by providing a prescribed switching means on the side face of a first or second main body. SOLUTION: This folding type portable telephyone set 8 is constituted of the main bodies 1 and 2 and the main bodies 1 and 2 are openably and closably connected through a connection part 3. The main body 1 is provided with a liquid crystal display device 4 for visibly displaying the respective kinds of information, an antenna 5 and a button switch 6. The switch 6 normally functions as the one for volume changeover and is used also as the switch for a special function. The switch 6 is provided on the side wall surface of the main body 1. Also, the main body 2 is provided with the respective kinds of function button switches 7 including a character/numeral input switch. Then, at the time of being operated in the state where the main bodies 1 and 2 are closed, the switch 6 validates a response holding function.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foldable mobile phone, and more particularly to a mobile phone capable of executing a response holding function in a folded state.

[0002]

2. Description of the Related Art Normally, when a mobile phone receives an incoming call and the user cannot receive the incoming call, the answer hold function is executed by pressing the end call key on the main body of the mobile phone. By notifying the base side that the called side executes this function, the base side puts the line into a response hold state, and the calling side makes an announcement that the called side is on hold.

[0003]

When the user performs the response holding function on the mobile phone, especially when the folding mobile phone is used, the main body must be opened in order to perform this function. It is necessary to press the end call key.

Therefore, the conventional foldable mobile phone has a problem that the operability when used is poor. Frequently, when there is an incoming call while driving a vehicle, a response holding function is often required, but this poor operability causes a safety problem.

An object of the present invention is to provide a mobile phone which can easily hold a response even when the main body is closed.

[0006]

A foldable mobile phone of the present invention has a first main body having a display for visually displaying various information, and various function switches including a start key and an end key. Second body that can be opened and closed with the main body
Body, a detection means for detecting the open / closed state of the first body and the second body, and a response holding function when the first body and the second body are operated in a closed state. And a switch means for enabling.

Further, the switch means is provided on a side wall surface of either the first main body or the second main body.

Further, when the switch means is operated when the first main body and the second main body are in the open state, other functions are enabled.

[0009]

Next, embodiments of the present invention will be described with reference to the drawings.

1 and 2 are views showing the outer appearance of a foldable mobile phone according to an embodiment of the present invention. FIG. 1 shows a state in which a main body is closed, and FIG. 2 shows a state in which the main body is opened. . Referring to both figures, this foldable mobile phone 8
Is composed of a first body 1 and a second body 2. The first main body 1 and the second main body 2 are openably and closably connected via a connecting portion 3. The first body 1 is provided with a liquid crystal display 4 for visually displaying various information, an antenna 5, and a button switch 6. The button switch 6 normally functions as a switch for switching the sound volume, but in the present invention, it is also used as a switch for a special function which will be described in detail later. In this embodiment, the button switch 6 is provided on the side wall surface of the first main body 1, but it may be located at any other position as long as it can be operated in the closed state. Further, the second main body 2 is provided with various function button switches 7 including character / number input switches.

Foldable mobile phone 8 having the above-mentioned structure
Is composed of the functional blocks shown in FIG. However,
The figure shows only the components necessary for the following operation description. Referring to FIG. 1, FIG. 2, FIG. 3 and FIG. 4 (flow charts for explaining the operation), the first main body 1 and the second main body 2 are closed while the power switch is operated and the power is turned on. In this state, if there is an incoming call on this mobile phone 8,
When executing the response holding function, the user first operates the button switch 6 provided on the side wall surface of the first main body 1.
The ON state of the button switch 6 is determined by the control circuit 10 as to whether the various function button switches 7 of the second body 2 are operated or the button switch 6 provided on the side wall surface of the first body 1 is operated. (Step S401 in FIG. 4). In this case, the control circuit 10 recognizes that the button switch 6 is operated based on an address signal or the like previously assigned to each button switch, but at this stage, it is unknown whether or not the button switch 6 has been operated for volume switching. is there. Therefore, the control circuit 10 determines the open / closed state of the first main body 1 and the second main body 2 (S402). Open / closed state detection circuit 1
1 inputs to the control circuit 10 a signal which detects that the first main body 1 and the second main body 2 are closed here. This open / closed state detection method can employ various techniques, but it can be based on the interruption of the loop state by the magnet as used for detecting the on / off hook state of the handset of the mobile phone. In this case, the control circuit 10
Knows that the button switch 6 was not operated to switch the volume but was operated to execute the response holding function. Therefore, the control circuit 10 detects whether the mobile phone is in the incoming call state (S403). As a result, when the control circuit 10 detects the incoming state of the mobile phone, the response holding operation is executed (S404). If the control circuit 10 does not detect the incoming call state, the operation normally used is executed (S405).

If the conditions are not met (No) in the determinations of S401 and S402 in the flowchart of FIG. 4, the operation is performed using the mobile phone in the normal state. As a result of the above-described processing, the user can perform the response holding operation with the main body closed. Further, in order to shift from the response hold state to the call state, the button switch 6
When pressing again, when the main body is changed from closed to open,
The start key may have been pressed in the open state.

When the button switch 6 is also used as a switch having another function as described above, it is possible to prevent an increase in the size and the number of parts of the telephone, and to suppress an increase in cost due to the function improvement.

[0014]

As described above, according to the present invention,
The response hold operation can be easily executed even when the main body is closed.
