Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a first housing and a second housing.
And a foldable portable wireless telephone device.

[0002]

2. Description of the Related Art In recent years, portable wireless telephone devices typified by portable telephones and PHSs have been downsized while the display unit has been increased in size. In such a situation, a foldable type including a first casing and a second casing has been widely used as a structure of a mobile wireless telephone device. As an example of this foldable portable wireless telephone device,
There is one disclosed in Japanese Patent Application No. 8-163219.

The portable radiotelephone device of the above publication has a first casing having a vertically long display on the front face, and an earpiece connected to the upper part of the first casing so as to be openable and closable. A second housing and a third housing, which is connected to the lower portion of the first housing so as to be openable / closable and provided with a keyboard portion, are provided.
Then, when the second housing and the third housing are opened, the front surface of the first housing and the inner side surfaces of the second and third housings are in a flat state, and the entire surface of the display is Widely exposed. As a result, it is possible to secure a wide display area that is convenient for sending and receiving electronic mail and browsing homepages on the Internet.

[0004]

However, in the conventional portable radio telephone device, since the width of the display is narrow,
Even if a large display area is secured and the number of characters that can be displayed is increased, the number of characters that can be displayed in one line is small and there are many line breaks, so that the visibility of the display has not been improved.

Further, since the display can be viewed only when the second casing and the third casing are opened,
The display cannot be seen easily and the operability is poor.

The present invention has been made in view of such circumstances, and the information displayed on the display is easy to read, compact when folded, the housing is small, and the cost is suppressed.
An object is to provide a mobile wireless telephone device having excellent operability.

By rotating the second housing in the direction of the arrow shown in FIG. 1, front surfaces 10a and 20a of the first housing 10 and the second housing are respectively, as shown in FIG. The sheets are folded so that they face each other and are closed. A part of the display 25, the receiver 27, the CCD 28 and the switch 29 are
In a state in which the respective housings are folded and closed, the housings are exposed in the direction of the back surface 10b of the first housing 10 through the cutout portions 11 of the first housing 10. By rotating the first case 10 in the direction of the arrow shown in FIG. 2B, the first case 10 and the second case 20 are expanded as shown in FIG. It becomes a state.

Next, a method of using the portable radio telephone device 1 shown in this embodiment will be described. First, the portable wireless telephone device 1
2 is stored in a pocket or the like, the front surface 10a of the first housing 10 and the front surface 20a of the second housing 20 face each other and are folded as shown in FIG. . When a call is received in this closed state, the operator first looks at the display of the display device 25 which can be visually recognized through the notch 11 of the first housing 10 to determine who the call is from. Check. At this time, the orientation of the characters on the display 25 is horizontal as shown in FIG. 2B and is the direction of the short side of the display 25.

When the operator wants to answer the call, he depresses the switch 29 to connect the line and make the call ready. The operator approaches the receiver 27 provided in the second housing 20 with his / her ears and talks to the other party by speaking into the microphone hole 15b provided in the back surface 10b of the first housing 10. Also, CCD while talking
When the image of 28 is to be sent, the CCD 28 is rotated left and right in the direction of the subject to determine the direction (the direction of the arrow in FIG. 2A), and the switch 29 is pressed to perform shooting and transmission. The CCD 28 rotates to the left and right, and the left and right direction is also the left and right direction of the image actually photographed and transmitted.

Next, a case where the operator wants to make a call by himself / herself or to input and send an electronic mail will be described. In that case, the operator, as shown in FIG.
0 and the second housing 20 are expanded to arrange the display device 25 in a horizontally long shape and expose the keys 16 and the numeric keypad 17. Then, while looking at the display 25 in which characters are displayed in the horizontal direction, a telephone number or an e-mail is input. After the input, the call or transmission key 16 is operated to make a call or send an e-mail to the other party. When making a call, the operator approaches the receiver 27 provided in the second housing 20 with his / her ear and speaks into the microphone hole 15a provided in the front surface 10a of the first housing 10 to talk to the other party. Have a conversation with.

When an e-mail is received and it is desired to confirm the content of the e-mail, a predetermined operation is performed with the key 16 to display the text of the intended e-mail on the display 25. The characters displayed on the display 25 are displayed long in the horizontal direction as shown in FIG. That is, even if the orientation of the display 25 is changed by closing or expanding the first casing 10 and the second casing 20 described above, the orientation of the displayed characters is constant in the lateral direction that is easy for the operator to see. Is. Since the direction in which the characters are displayed is constant regardless of the direction of the display device 25, the operability is excellent.

When it is desired to take a picture with the CCD 28 in this expanded state, the CCD 28 is rotated in the vertical direction to determine the direction, and the picture is taken by a predetermined operation such as pressing the switch 29. In this case, the vertical direction in which the CCD 28 rotates is the vertical direction of the image actually shot. That is, in the state where the first casing 10 and the second casing 20 are closed, the orientation (up / down / left / right) of the captured image is 9
It will change 0 degrees. Since the orientation of the captured image is constant regardless of the orientation of the CCD 28, the operability is excellent.

According to the portable radiotelephone device 1 of this embodiment, when the first casing 10 and the second casing 20 are expanded and opened via the hinge portion, the second casing 20 is provided. The rectangular display 25 provided is arranged horizontally. Therefore, the display 25
It is possible to increase the number of characters displayed in one line, and it is possible to easily display information with a large number of characters such as a long-sent e-mail. Further, when the first casing 10 and the second casing 20 are closed, the respective casings are folded and folded to have a compact shape, and it is easy to store them in a pocket or the like.

Further, in a state where the first casing 10 and the second casing 20 are closed, the display 25 can be visually recognized from the back surface 10b of the first casing 10 through the notch 11. For this reason,
