(2) signal wire/Connection Block used in the present invention is the earphone cord/earphone socket that is found everywhere, and part is taken especially convenient;
(3) the present invention only needs the signal wire two ends are inserted respectively in keyboard/wireless signal receiver, can be to the battery charge in the keyboard; So can utilize booting computer but the neutral gear charging of user's rest, need not is that battery is made extra charging module, and saves timeliness.
Below in conjunction with accompanying drawing, embodiments of the invention are described, wherein:
Fig. 1 is the circuit diagram of one embodiment of the invention;
Fig. 2 can wireless transmission for the present invention or the synoptic diagram that carries out button/rocking bar signal transmission with earphone cord;
Fig. 3 is the present invention during with wireless transmission, the synoptic diagram that power supply/signal connects;
When Fig. 4 carries out wire transmission for the present invention with earphone cord, the synoptic diagram that power supply/signal connects.
As shown in Figure 1, the present invention be a kind of can wire transmission and the dual-purpose keyboard 30 of wireless transmission, this keyboard 30 can cooperate a computer system signal receiver 40 and with the wireless mode transmission signals, this keyboard 30 also can be electrically connected this signal receiver 40 and with wired mode transfer signal, and this keyboard 30 comprises that a processor 10, a power supply stabilization circuit 11, switch switch 13, a transmitting terminal Connection Block 14, can charge and discharge a battery 15 and a wireless signal transmitting device 16 (for example infrared signal/RF signal).Power supply stabilization circuit 11 comprises a reducing transformer R5, a voltage stabilizing Zener diode D5, and+5V power supply can offer processor 10 stable power after the effect of step-down and voltage stabilizing.
This processor 10 can produce the push button signalling of a correspondence in response to user's button enter action.These wireless signal transmitting device 16 exportable these push button signallings are to the signal receiver 40 of this computer system; This battery 15 can provide this processor 10 and the required electric power of this sender unit 16 runnings.Shown in Fig. 2,4, this transmitting terminal Connection Block 14 can be electrically connected a signal wire that comprises three data lines, three data lines can transmit respectively this computer system power supply (+5v), the reference ground end signal (GND) of this computer system and the push button signalling/rocking bar signal (Data) of this keyboard.
Cooperate the present invention, comprise a receiving end Connection Block 29, a processor 24, a wireless signal receiver 20 in the signal receiver 40 of computer system side.This receiving end Connection Block 29 is electrically connected a signal wire that comprises three data lines movably; Similarly, these three data lines can transmit respectively this computer system power supply (+5v), the push button signalling/rocking bar signal (Data) of the reference of this computer system ground end signal (GND) and this keyboard.Shown in Fig. 2,4, a most preferred embodiment of signal wire is for generally comprising the earphone cord of three data lines, and a most preferred embodiment of Connection Block is common general earpiece holes seat.
Be provided with a vernier input media (for example trace ball, rocking bar) on the keyboard 30 of present embodiment simultaneously, this vernier input media can be in response to user's vernier input action, produce the vernier movable signal of a correspondence, and the push button signalling of this keyboard 30 and shared same the data line of this vernier movable signal (Data).Can be three bit groups (Byte) by the coded format of this vernier movable signal of definition: " F5, X displacement, Y displacement "; And the coded format of this push button signalling is three bit groups: " Non-F5, ASCII 1
STByte, ASCII 2
NdByte ".Therefore this signal receiver knows that promptly received data is " push button signalling " or " vernier movable signal " at present as long as judge whether the first tuple (Leading Byte) of data line institute data transmission is F5.As for the transformat of bit group 40 of keyboard 30 and signal receivers, present embodiment is followed UART (RS-232) Interface Standard that general PC adopts, and does not repeat them here.
When keyboard 30 is operated with wireless mode, use battery 15 power supplies, processor 10 is passed to signal receiver 20 with button/rocking bar signal via wireless mode (with infrared ray (IR) or radio frequency (RF)).And signal receiver 20 will be received button/rocking bar signal, and reach processor 24 in this signal receiver 20 by signal wire, after finishing, processor 24 decodings are reduced to the keyboard/rocking bar input instruction of standard, deliver to the keyboard interface of computer system more respectively, as serial port (Serial Port) or PS/2 port, shown in Fig. 2,3.
The Connection Block 14 that inserts keyboard 30 respectively when the signal wire two ends is during with the Connection Block 29 of receiver-side, system side+5V power supply, earth terminal, button/rocking bar signal be connected on the keyboard 30 by signal wire.Switch 13 has two windings point, one group be responsible for charging and discharging battery 15 and computer system+switching of 5V power supply, another group is responsible for that keyboard/rocking bar instruction reached infrared transmitting device 16 or is reached button/rocking bar signal wire (data) on the signal wire.Promptly when this signal wire was not electrically connected this transmitting terminal Connection Block 14, this change-over switch 13 was selected 15 pairs of these processors 10 of this battery and 16 power supplies of this wireless signal transmitting device, and made this push button signalling via these wireless signal transmitting device 16 outputs; When this signal wire was electrically connected this transmitting terminal Connection Block 14, this change-over switch 13 selected the power supply of this computer system to these processor 10 power supplies, and makes this push button signalling via these transmitting terminal Connection Block 14 outputs.
It can be Purely mechanical that these keyboard 30 signal lines have or not the implementation method of insertion, and the butt switch switches when being inserted by earphone cord; Or, be responsible for detecting on the Connection Block 14 as the 34th leg and whether have+power supply of 5V with a certain leg of processor 10.Exist if detect power supply, representing keyboard 30 is that the ray mode operation is being arranged, and processor 10 is via this transmitting terminal Connection Block 14 output keys/rocking bar signal, as shown in Figure 4.When this signal wire was electrically connected this transmitting terminal Connection Block 14, if battery 15 is one can charge and discharge battery, then this keyboard 30 also can utilize computer host power supply that this battery 15 is charged.
