DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the operability of a portable radio information terminal or the like, and more particularly to the operability of an operation screen and a lid attached so as to cover the operation screen.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 3, a portable radio information terminal of this type includes a main body 11, a cover 14 provided on the main body 11 so as to be rotatable with a hinge, and a pen or An operation screen 13 that can be touch-operated by a finger and a transmission unit 15 are formed.
, Key buttons 16 and a window 14a.

[0003] In the portable radio information terminal thus formed, the voice communication is performed with the lid 14 closed. In addition, when the lid 14 is closed, a touch input can be performed on a corresponding portion of the operation screen 13 by pressing the key button 16,
When the cover 14 is open, an input operation is directly performed on the operation screen 13 with a pen or the like.

As described above, when the cover 14 is open, the operation screen 13 is made pen input-capable, and when the cover 14 is closed, touch input by the key buttons 16 is enabled. The operation screen 13 is operated by a changeover switch (not shown) that operates in response to the closed state.
Is switched to the display corresponding to the input by the key button 16. The above technology is disclosed in Japanese Patent Application Laid-Open No. 8-29.
7639.

[0005]

In the above-mentioned conventional portable radio information terminal, since the receiving section 12 is incorporated in the lid section 14, the voice communication must be performed with the lid section 14 closed. When the cover 14 is closed, the operation screen 13 is switched for key button input, and the key buttons 16 provided on the cover 14 can be operated with the key buttons 16. When the unit 14 is open, the operation screen 13 is switched for input by a pen or a finger, so that the operation with the key buttons 16 cannot be performed, and there is a disadvantage that the operation must be performed only by the touch operation of the operation screen 13.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a portable wireless information terminal having a receiver, a transmitter, an input operation screen, and an openable / closable lid. An object of the present invention is to provide a terminal with improved operability capable of performing a call and operating a key button.

[0007]

A portable wireless information terminal device according to the present invention has a receiving unit, a transmitting unit, an input operation screen, and an openable / closable lid provided on a main body of the device. When the is closed, it is provided so as to cover the operation screen but not the reception section and the transmission section. Therefore, voice communication is possible in the closed state as well as in the opened state.

The lid is provided with key buttons that can be operated for input from the front side and the back side. When the lid is closed, the key buttons are pressed on the operation screen by pressing from the front side of the lid. When the cover is opened, the input is performed directly by pressing a key button from the back side of the cover. In this case, it is needless to say that pen input on the operation screen is possible.

In order to perform the above operation, a changeover switch for closing the circuit when the cover is opened and electrically connecting the key button to the control unit of the apparatus main body is provided. The changeover switch is opened when the cover is closed, and the electrical connection between the key button and the control unit is cut off. Therefore, when the key button is pressed from the front side of the lid with the lid closed, the key button can directly contact the operation screen to perform input.

When the lid is closed, the operation screen display is switched from the input corresponding display using a pen to the input corresponding display using a key button, so that the display can be viewed from a window provided in the lid. Is preferred.

[0011]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a perspective view of the appearance of a portable wireless information terminal device of the present invention.

The main body 1 is a substantially rectangular parallelepiped housing, and a receiving section 2 is provided at an upper portion, and a transmitting section 5 is provided at a lower portion. An operation screen 3 is provided at the center of the housing. The operation screen 3 includes an operation unit 3b that can be input by pressing.
And a display unit 3a for displaying an input result, and is usually called a touch panel. The lid 4 is provided at the lower end of the main body 1 so as to be rotatable by a hinge, and is a plate-shaped cover for covering the operation screen 3 when closed.
Is provided with a window portion 4a for viewing the display portion 3a of the operation screen 3 when is covered.

A plurality of key buttons 6 are provided on the lid 4.
It is provided so that it can be operated from both the front side and the back side. When the cover 4 is closed and covers the operation screen 3, the key button 6 is depressed by pressing the key button 6 from the front side of the cover 4, so that the key button 6 contacts the operation unit 3 b of the operation screen 3. An input signal can be sent to a control unit (not shown) in the main body and input. When the lid 4 is open, a changeover switch 7 provided in a circuit connecting the key button 6 and the control unit 8 inside the main body 1 is operated as shown in the block diagram of the internal circuit of the main body shown in FIG. To close,
The key buttons 6 are electrically connected to the control unit 8. Therefore, in FIG. 1, if the key button 6 is operated from the back side of the lid 4, a signal can be directly input to the controller 8. When the cover 4 is closed, the changeover switch 7
Is released, so that the operation of the key button 6 presses the operation unit 3b of the operation screen 3 to input a signal to the control unit 8 as described above.

The changeover switches 7 are not shown in FIG. 1, but can be easily provided as a pair at the positions corresponding to the hinge or the main body 1 and the cover 4 by a known method.

Although only two key buttons 6 are shown in FIG. 1, any number of buttons required for operation can be provided according to the application.

[0016]

As described above, according to the present invention, the cover of the main body is provided so as not to cover the receiver and the transmitter.
Even when the lid is open, it has the effect of enabling voice communication in the same way as when the lid is closed.Also, the display on the operation screen can be seen even when the lid is closed, and the key on the lid Since the buttons are configured to be operable from both sides of the lid, the key buttons can be operated even when the lid is open as in the closed state, and the operability is improved.
