Definitions

• the present invention relates to a portable communication device having a casing provided with first and second keypads arranged on opposite sides of the casing, and a common display for operating the device.
• the two separate keypads functions as both a telephone and a QWERTY-terminal for sending and receiving sound and alphanumeric and/or graphical information.
• a communication device such as a mobile telephone or a mobile station
• the common way of writing and sending messages is to use the keypad of the telephone for inputting information. This is unpractical due to few and small buttons of the keypad.
• QWERTY-keypad can an expanded communication function easier to use be achieved.
• the most common kind of device comprises two halfs of about the same size pivotally attached together by a hinge, each half having a separate display and in which the halfs can be unfolded, whereby the QWERTY-board together with a bigger display compared to the display at the other half are revealed and ready for use.
• Such a device is disclosed in EP-A1-776 140.
• EP-A2-472 361 Another solution disclosed in EP-A2-472 361 is to join two parts, a portable PC and a mobile telephone, pivotally together as one device with a common display, whereby the PC and the telephone, each having a separate keypad, are placed in one half of the device and the display is placed in the other slightly bigger half of the device.
• the half with the PC, telephone and adherent keypads covers a part of the display arranged in the other t o o S
• the size and weight of the device are reduced due to a smaller display located in a cavity in a first position, thereby requiring less space when put into a pocket or the like .
• FIG 1 is a front view of a communication device with a pivotable display in a first closed position according to a preferred embodiment of the invention
• FIG 2 is a side view showing the communication device with the pivotable display, which is folded up and is shown in a position before it is visible from the back side of the communication device;
• FIG 3 is a side view showing the communication device with the pivotable display in the first position; and FIG 4 is a view of the back side of the communication device with the QWERTY-keypad and the display in their second fully opened position for usage.
• FIGS 1-4 illustrate a preferred embodiment for operating and simplifying the handling and transportation of a communication device 1.
• the communication device 1 is a radio telephone, such as a mobile or cellular telephone.
• the device 1 comprises a casing 2 provided with first and second keypads 3,4 arranged on opposite sides of t to o ⁇ _n
