Pager with rotating knob and character display for inputting messages |
摘要 |
A pager allows the input and transmission of a virtual unlimited range of messages. The pager comprises a character display control knob which controls the sequential display of alphabetic and numeric characters on a display. By rotating the knob, the displayed character advances or retreats through the appropriate alphabetic or numeric sequence. When the character is displayed that the pager user wishes to include in a message to be transmitted, the pager user presses a selection key. The process is repeated until the message is completed. The pager may then transmit the message to a paging system by radio transmission to a base station or by emitting a series of sounds in which the message is encoded. In the case of emitted sounds, the sounds are conveyed along an open phone line to the paging system where they are decoded.
