Description
Technical field
The utility model relates to a Wireless Keyboard (wireless keyboard) that can cooperate radiation signal receiver (the radiation-based signal receiver) transmission signals of Portable calculation element (portable computingapparatus), particularly relates to this Wireless Keyboard and has and improve the function of radiation delivery to the radiation signal receiver of Portable calculation element.
Background technology
Along with the development of technology and in response to consumer demand, there are more and more more small-sized, special Portable calculation elements to be devised, for example personal digital assistant (personal digital assistant, PDA), mobile phone (mobile phone), Espresso (pocket computer) and other similar products.The user has begun to tend to use more small-sized similar products such as PDAs, these products to provide in design than the less performance of personal computer (PC), but computer function the most basic with commonly used is provided, and is designed to place pocket to carry.These specific functions may comprise routing, address database, blank form application program and processing of simple document or summarization application etc.
These Portable calculation elements typically are referred to as digital information device, computerized information equipment etc.Some Portable calculation element association class is like the function and more powerful application function of PDA, and for example the Internet connects and the email function.In this class example, have the touch screen that similar PDA searches simple functions such as telephone number or calendar simultaneously, and keyboard arrangement easily such as the long email of layout, file, be more welcome.The related keyboard that can convenient collect then can be of great use.
Under the consideration of convenience, Wireless Keyboard is used with the Portable calculation element widely.Particularly, infrared and radio keyboard (infrared wireless keyboards) cooperates the use of Portable calculation element to be widely known by the people.The infrared and radio keyboard just utilizes the infrared receiver (infrared receiver) on infrared transmitter (infrared transmitter) and the Portable calculation element on the keyboard simply, sets up being connected between keyboard and the Portable calculation element.The infrared and radio keyboard does not need an entity metal wire to connect keyboard and calculation element certainly, does not therefore have the problem that circuit tangles.
Yet the infrared and radio keyboard has a lot of shortcomings.Particularly in the transmission path between the infrared receiver of the infrared transmitter of infrared and radio keyboard and Portable calculation element, barrier can not be arranged.No matter when, the Portable calculation element all needs infrared receiver to be arranged on the specific position of this Portable calculation element, could between the infrared receiver of the infrared transmitter of infrared and radio keyboard and Portable calculation element, set up the possibility of delivering path, and then the decision Wireless Keyboard could use.
Pocketop Computer Company has developed the annex that a kind of infrared and radio keyboard, and this annex can cooperate the Portable calculation element to use, and this Portable calculation element then is provided with infrared receiver on its top margin or near top edge.This annex comprises that a support and is connected the reflecting surface version on support.The Portable calculation element can firmly erect by relying on support, in this example, the reflecting surface version can with from the infrared reflection of infrared transmitter to infrared receiver.Yet clearly, the solution that Pocketop company is provided is only to be applied to the Portable calculation element that infrared receiver is arranged on its top margin or close top edge.When the infrared receiver of Portable calculation element is located at its specific position, for example waist limit or back of the body limit, existing Wireless Keyboard just can't use.
The infrared ray direction that Gateway 2000 companies have utilized various improvement to dispose to adjust the infrared transmitter be located on the electronic installation to transmit.Improve configuration about these and be described in detail in United States Patent (USP) the 6th, 104,606,5,978,214,5,978,213, and 5,781, No. 405 in have clear the exposure.Yet clearly, the solution that Gateway 2000 companies are provided can not be applied in Portable calculation element light and handy, that be furnished with infrared receiver.Even according to above-mentioned prior art, promptly the infrared transmitter of Wireless Keyboard can adjustment itself the infrared ray direction of emission, but be located at its top margin or near the Portable calculation element of top margin, Wireless Keyboard still can not be used for infrared receiver
In addition, the distance between infrared and radio keyboard and the Portable calculation element can not be too big, otherwise the infrared receiver on the Portable calculation element can not detect the infrared ray that the infrared transmitter of infrared and radio keyboard is launched.Can not there be barrier in path between transmitter and receiver and needs less conditions such as distance, these can limit the elasticity that the user uses keyboard, because exist the artificial restriction of position and distance between infrared and radio keyboard and Portable calculation element.
In addition, the infrared and radio keyboard needs a large amount of power consumptions because infrared transmitter is arranged.Six volts of power supplys that the infrared and radio keyboard needs four 1.5 voltaic elements to be provided usually operate.And the power consumption that increases will reduce the life-span of all batteries, so that battery must upgrade more normally.
