The action of remote control transmitter 10 is to utilize microcomputer 1 to control, and as shown in Figure 1, is connected with by a plurality of keys 11,11 with microcomputer 1 ... the keyboard switch 12 that is constituted.Keyboard switch 12 is to reach the input lead figure 13B mutual insulating and rectangular being disposed on the not shown printed-wiring board (PWB) of being drawn by the input signal terminal of KI0 and even KI3 by the output lead figure 13A that the input/output signal terminal of the KI/O1 to KI/O6 of microcomputer 1 is drawn, and the pair of switches electrode is connected to output lead figure 13A and the input lead figure 13B that intersects at crossover location respectively, and forms key 11.A pair of switch electrode is to utilize the action button of the not shown rubber sheet of input operation key 11 to be connected to each other, and by like this, microcomputer 1 detects operated key 11 by this.
That is, microcomputer 1 comes periodically run-out key sweep signal with mutual different sequential from KI/O1 to KI/O6, if one of them key 11 is transfused to operation, then can the key scanning signal occur, therefore can detect the input signal terminal of enter key sweep signal, and by the operated key 11 of this input timing in one of them of KI0～KI3.
Vdd terminal of microcomputer 1 is connected with direct supply 14, and with VSS terminal ground connection, VDD imports as driving power with direct supply simultaneously.At this, direct supply 14 is the batteries that are contained in the shell of remote control transmitter 10.In addition, at this, for the supply voltage that makes input microcomputer 1 stable, and with direct supply 14 capacitor 15 that is connected in parallel, but, then needn't be provided with if dc voltage stability reaches the degree that can not influence the action of microcomputer 1.
The REM terminal of microcomputer 1 is to be connected with the anode of infrared light-emitting diode 16 without on-off element, by controlling the output current of directly being exported from the REM terminal, controls the luminous of infrared light-emitting diode 16.
Fig. 2 is the formation block scheme in this microcomputer 1 of expression, microcomputer 1 produces circuit part 6, light emitting element driving circuit 7,9-bit timer 8 etc. via bus under the interconnected state in the CPU2 of input/output port KI/O, input port KI, executive utility, the PROM3 that stores application program etc., computing with RAM (Random Access Memory) 4, RC oscillatory circuit 5, carrier wave, be integrated in 1 IC chip, and enclose packaging body.
Input/output port KI/O is 6 input/output ports via the input/output signal terminal of the KI/O1～KI/O6 of not shown interface and microcomputer 1, in order to utilize the control of CPU2, detect the key 11 of the input operation of keyboard switch 12 as previously mentioned, and come the run-out key sweep signal with mutual different sequential from each input/output port.Again, input port KI is with 4 input ports of Specifications ground via not shown interface and signal terminal (KI0 and even KI3), imports above-mentioned key scanning signal.
CPU2 is computing and the action that puts rules into practice according to the application program that is stored in PROM3, and as described later, when connecting online write device, the application program from online write device output can be write PROM3.
Each key 11,11 to keyboard switch 12 ... give the control command of the actions such as power supply, volume, channel switching of for example television receiver of relevant controlled device, in case detect operation to specific key 11 according to one of them the key scanning signal that inputs to input port KI, then CPU2 can produce the PPM modulation signal after PPM (Pulse Position Modulation, the pulse position modulation (PPM)) modulation with the control command of the action relevant with this key 11.
In be loaded on the PROM3 of microcomputer 1, be to use OTP (One Time programmable, disposable programmable) ROM at this.The application program that is stored in OTPROM3 is when microcomputer 1 is mounted to remote control transmitter 10, that is the not shown printed-wiring board (PWB) of remote control transmitter 10 is being installed in the operation of microcomputer 1, utilize be arranged at the same line of hookup wire on online write device write the regulation zone of OTPROM3.Though PROM3 is nonvolatile memory originally, must bottom line be the storage component part that can rewrite, therefore be loaded on the address bus of PROM3 of microcomputer 1 and data bus etc. in and directly do not draw the outside.So, when PROM3 is write application program, as mentioned above, the pattern of microcomputer 1 is switched to the pattern of writing, by microcomputer 1, utilize the signal terminal of drawing in order to be connected with peripheral circuit and system, be the signal terminal (KI that is connected with keyboard switch 12 at this, KI/O) as the signal terminal that PROM3 is carried out access, write application program.
As mentioned above, in be loaded on microcomputer 1 CPU2 produce the control command of controlling the action of controlled device corresponding to the key 11 of institute's input operation, therefore according to the controlled device of institute's remote control, will write OTPROM3 corresponding to the application program of each controlled device.If utilize the present invention, then can be manufactured on the mask rom that writes each application program in the processing of wafers operation to each controlled device, as long as prepare to contain the mini-computer 1 of OTPROM3 in advance, just can be installed the stage that microcomputer 1 is assembled, to write OTPROM3 corresponding to the application program of each controlled device, therefore can be at short notice, and under must stock's situation, make the remote control transmitter 10 that makes various controlled devices actions.
Computing RAM4 is application program or the operation result of CPU2 and the data that produced etc. of storing among the temporary transient storage OTPROM3 in the action of microcomputer 1.
RC oscillatory circuit 5 is to produce for example clock of the assigned frequency of 4MHz in microcomputer 1, and 9-bit timer 8 is this clock frequency division, produces the frequency of the carrier wave that circuit part 6 produced as carrier wave.RC oscillatory circuit 5 is to constitute with transistor combined capacitor and resistance, so integrability, and compare with other oscillatory circuit, vibrational stabilization, even in be loaded on microcomputer 1, the vibration precision is remained in the error about 2%, can not hinder the action of remote control transmitter 10, can in be loaded on microcomputer 1.
Carrier wave produces circuit part 6 according to the frequency signal of being exported from 9-bit timer 8, produces the carrier wave of fixed frequency.
Light emitting element driving circuit 7 is when detecting arbitrary operated key 11, the PPM modulation signal that utilizes CPU2 to produce, the carrier wave of secondary modulation said fixing frequency is according to the modulation signal after the secondary modulation, from the drive current of REM terminal output infrared light-emitting diode 16.That is, for example, if the modulation signal outgoing carrier during the PPM modulation signal is in high level after the secondary modulation, stop the exporter during low level being in, then can be in high level during, make the drive current of infrared light-emitting diode 16 flickers with the fixed frequency of carrier wave from REM terminal output.
Therefore, the luminous meeting of infrared light-emitting diode 16 is controlled according to modulation signal (control command of the action that the particular key 11 of expression and institute input operation is relevant), and makes the infrared control signal that comprises control command luminous from remote control transmitter 10.The controlled device, for example television receiver of accepting this infrared control signal be from infrared control signal demodulation control command, carries out the action relevant with the key 11 of institute input operation according to control command.
Light emitting element driving circuit 7 is the on-off elements that are equivalent to drive controlling and the 1 other infrared light-emitting diode 16 that is provided with of microcomputer in the past, but on-off element integrability with the transistor formation, and be the parts that different remote control transmitters can be general, so be loaded on element among the present invention being as the microcomputer 1 of general small incidental expenses parts.
So the microcomputer 1 that constitutes is formed with in printing by welded and installed on the printed-wiring board (PWB) of switch electrode, output lead figure 13A and input lead figure 13B of keyboard switch 12, welded and installed to the lead-in wire figure of input/output signal terminal, input signal terminal, REM terminal vdd terminal etc.Microcomputer 1 in 1 IC chip in the dress remote control transmitter 10 the necessary main circuit parts of action, therefore be installed in other parts of printed-wiring board (PWB), as shown in Figure 1, the capacitor 15 that have only infrared light-emitting diode 16, connects the battery terminal of direct supply 14 usefulness and be provided with in case of necessity, the installation component number reduces, installation procedure is simplified, and printed-wiring board (PWB) is dwindled.
For the printed-wiring board (PWB) after the above-mentioned parts beyond the installation microcomputer 1, each switch electrode for overlay keyboard switch 12, overlapping be arranged at the flexible rubber sheets of movable electrode interior surface opposing, and be loaded in the insulation crust, thereby make remote control transmitter 10.
In above-mentioned example, microcomputer 1 is that the IC chip is enclosed packaging body, and the welded and installed such as input signal terminal that will draw from microcomputer 1 are to the lead-in wire figure of the correspondence of printed-wiring board (PWB), but also can not enclose packaging body, under the state of the bare chip that IC is exposed, the bonding point of each terminal that is equivalent to the microcomputer 1 of input/output signal terminal, input signal terminal etc. is connected to the pairing lead-in wire figure of printed-wiring board (PWB) with the bonding fine rule.
So, utilize the lead-in wire bonding that microcomputer 1 is mounted to printed-wiring board (PWB), can make remaining infrared light-emitting diode 16, battery terminal and capacitor 15 be connected to the lead-in wire figure of printed-wiring board (PWB), can fully use manufacturing remote control transmitter 10 under the plumbous situation not use plumbous scolding tin line.
Again, owing to not be used in the reflow ovens that the printed-wiring board (PWB) that microcomputer 1 will be installed in the mounted on surface operation is disposed at high heat, or impregnated in the solder bath of high heat, so can use and do not require and can reduce cost stable on heating material.
In this example, because can't write application program being mounted to the preceding of printed-wiring board (PWB), go up the printed-wiring board (PWB) that placement is equipped with microcomputer 1 so carry write device (on board writer) at plate, make that being connected to relative plate respectively with the lead-in wire figure of the printed-wiring board (PWB) of bonding point connection carries writing of write device (onboard writer) and use terminal, move according to the boot that is stored in PROM3 in advance, come PROM3 is write application program arbitrarily via the input and output pin of microcomputer 1.At this, boot is that to make CPU2 to microcomputer 1 energized the time be the program that writes when being written in the manufacturing of PROM3 of PROM3 pattern.
In above example, with regard to PROM, be to be that example describes with OTPROM, as long as but can after ROM makes, write application program at least, then also can be PPROM (Productionprogrammed read only Memory, production programmable read only memory) but or the mat ultraviolet irradiation come delete program and the EPROM that rewrites with the EPROM Writer of special use or but the mat electric signal is freely deleted and the flash ROM (EEPROM) of rewriting program etc.
Again, in the above-mentioned example, be that microcomputer 1 is mounted to the printed-wiring board (PWB) that printing is formed with the switch electrode of keyboard switch 12, but keyboard switch 12 also can form general's figure electrical connection each other again on the substrate different with the printed-wiring board (PWB) that microcomputer 1 is installed.For example, keyboard switch can be: folded flexible ambroin made membrane substrate across very little clearance for insulation, on relative opposite face, with conductive paste printing movable electrode and fixed electorde, thereby forms key 11.Form keyboard switch with the flexible insulation plastics made membrane substrate that can print electrode etc. if so, then the layout changing of electrode and lead-in wire figure just can solve as long as film substrate is changed printed pattern.Therefore, can form the keyboard switch of the different various layouts of the position of key or quantity, will be corresponding to the different application storage of bond number in PROM, thus also can make the remote control transmitter of different keyboard switches at short notice.
Again, in the above-mentioned example, the capacitor 15 that is parallel to direct supply 14 is to be installed in printed-wiring board (PWB) with discrete parts, but also can be by being loaded on microcomputer 1 in integrated.
