Further, the present invention provides a portable terminal that is configured to be opened and closed by a first casing having a display unit and a second casing having a first operation unit, and the display unit is always visibly exposed. At least one of the two housings is provided with an exposed second operation portion, and detecting means for detecting a relative position between the first housing and the second housing, and an operation of the exposed second operation portion. If detected, a list of application names is displayed on the display unit, and when one of the application names is displayed on the display unit, one of the applications can be selected based on the relative position of the detection unit, Control means for executing the selected application when it is detected that the second operation unit has been pressed is released.

  According to the present invention, in a portable terminal having an openable / closable structure, a specific function is activated by an operation of opening any of the housings, thereby enabling a simple and smooth operation. Therefore, the function to be activated after being opened can be activated without the subsequent operation of the keypad or the like, and the time from when the user wants to activate to the time when the function becomes usable can be shortened. it can.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a front appearance of a slide type mobile phone as a portable terminal that can be opened and closed according to an embodiment of the present invention.
The telephone is composed of a first casing 100 and a second casing 101 that slide and overlap each other. The first housing 100 can be used even when the handset 102, the display device 103, the first housing 100 and the second housing 101 are completely overlapped, that is, the first housing 100 and the second housing 101. A key 104 that is exposed regardless of the relative position is provided.

  On the second housing 101, a key 105 and a keypad 106 for operating as a telephone, a transmitter 107 for inputting a transmission voice, and a positional relationship between the first housing 100 and the second housing 101 There are optical sensors 110, 111, 112, 113 for detecting, and a key 108 and a key 109 that can be used during a call or the like on the side surface.

FIG. 2 is a rear view of the mobile phone.
On the back side, a camera unit 114 capable of shooting an image is installed in the first housing 100.
When the first casing 100 and the second casing 101 make a call, perform an operation using the keypad 106, or shoot an image with the camera, the extended state (open state) as shown in FIG. In the case of transportation, only when the display is confirmed, the contracted state (closed state) as shown in FIG. 3 is used.
The user carries the phone in the normal contracted state, and when making a normal call, after making the expanded state, the user inputs a destination telephone number from the keypad and makes a call.

When the display device is in the extended state during standby, it is turned on if the display device is turned off to save power, and the keypad illumination built in the keypad is also turned on.
When an incoming call is received, it responds with an outgoing key input on the keypad in the extended state. In the contracted state, it automatically transitions to the response state by expanding. This transition may be switchable to “do nothing”, “transition to silent mode”, or the like according to the user's prior selection.

  The movement from the contracted state to the extended state is performed by the optical sensor 110, the optical sensor 111, the optical sensor 112, and the optical sensor 113 arranged side by side in the direction of the relative movement of the first casing 100 and the second casing 101. Is detected. The light sensors 110 to 113 are in an H level state in which the output voltage is larger than a certain threshold when light from the outside is detected, and when the surface is shielded and no light is detected, the output voltage is smaller than the certain threshold. It becomes the state of L level which becomes.

Next, the configuration of the control system of the mobile phone will be described with reference to FIG.
The mobile phone control system includes an antenna 10 used for radio communication with a base station, a radio processing unit 11 that performs radio processing on a signal received from the antenna, a radio communication protocol process, and various processes inside the mobile phone. CPU 12, RAM 13, ROM 14, functioning as control means to perform, first operation unit 15 functioning as the key 105 and keypad 106, second operation unit 16 functioning as the key 104, functioning as the display device 103 and its drive circuit And a detection means 18 for detecting the opening operation of the cellular phone by the optical sensors 110 to 113 and the like.

Due to the control system, the cellular phone operates as follows in accordance with the opening / closing operation.
In the contracted state as shown in FIG. 3, all the optical sensors 110 to 113 are shielded by the first casing 100, and the output voltages of the optical sensors 110 to 113 are at the L level. During the transition from the contracted state to the extended state after starting the slide (for example, the state shown in FIG. 5), the optical sensor 113 receives light and the output voltage becomes H level, while the optical sensors 110, 111, and 112 are still shielded. The output voltage remains at the L level. When the slide further progresses to a transition state close to the extended state as shown in FIG. 6, the optical sensors 111, 112, 113 are not shielded by the first casing 100, and the output becomes the H level.
As described above, the slide positional relationship between the first casing 100 and the second casing 101 is detected based on the output voltage level of each optical sensor according to the determination according to the table shown in FIG.

Keys 108 and 109 operate as buttons for controlling the reception volume during a call, and function as keys for turning on a display unit that is turned off for power saving during standby in a contracted state.
When the key 108 is pressed and it is detected that the contracted state is changed to the extended state, the mode automatically shifts to the camera photographing mode.
When the terminal detects that the key 108 has been pressed and has changed from the contracted state to the transition state, the terminal starts the application application of the camera, and shortens the time from the start of the operation to the shooting enabled state.
However, when the transition state does not change to the expansion state and the contraction state is restored, the activation is stopped and the state before the activation is restored.
In the shooting mode, an image input from the camera is displayed in real time on the display device, the key 105 functions as a shutter, and the image is taken into the internal memory when pressed.

When the key 109 is pressed and it is detected that the contracted state is changed to the expanded state, the e-mail application is activated, and the e-mail creating function is entered.
In the e-mail creation function, an e-mail is transmitted by inputting a destination, a title, a body text, and the like and then pressing a key for instructing transmission.
Further, the display means 103 detects pressing of an exposed key and shows a list of application names to be activated in accordance with a slide operation. For example, in FIG. FIG. 6 shows that the camera application is an activation target. When it is detected that the pressed key is released, the application selected on the display means 103 is activated.
In addition to pressing the key, the operation of the second operation unit such as turning on the switch mechanism by a slide switch is also included.
The mobile terminal of the present invention includes a mobile phone, a personal digital assistant (PDA) and the like.

According to the present embodiment, a specific function is activated simply by changing a contracted state to an expanded state while a specific key that can be pressed in the contracted state is pressed, and a simpler operation is possible.
As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the specific structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.
