`
`Detailed Description of the Invention
`
`0001
`Field of Use in Industry
` The present invention relates to a remote control device performing remote control of
`household electronic devices etc.
`
`0002
`Prior Art
` Previously, pure remote control devices have been included with electrical devices such
`as television receivers or video tape recorders etc., and learning remote controls or ROM
`remote controls have been provided as remote control devices that can be used in
`common among different manufacturers or types.
`
`0003
` The aforementioned learning remote controllers are designed to receive and store
`remote control codes sent from a pure remote controller, and to play them back according
`to key operations, and [thus] can correspond to remote control devices for different
`devices, and such learning remote controllers must record remote control code sent by
`each keystroke of each key of the pure remote controller, one keystroke at a time.
`
`0004
` For this reason, a very high number of key operations are involved in making remote
`control code settings corresponding to the aforementioned pure remote controller, which
`is troublesome and prone to setting errors. On the other hand, the latter [device], a ROM
`remote controller, previously stores remote control codes for each different manufacturer
`in internal ROM and the remote control code corresponding to a given manufacturer is
`transmitted by a designated key operation for an input setting for manufacturer codes
`corresponding to a desired manufacturer. Thus although such ROM remote controllers do
`not have troublesome operations involving sequentially storing all remote control code
`for all keys as in the case of the aforementioned learning remote controller, they do
`involve the time and effort of knowing who is the manufacturer of the device to be
`operated, and selecting and setting the manufacturer code for that manufacturer.
`
`0005
`Problem to be Resolved by the Invention
` Accordingly, the aforementioned learning remote controllers and ROM remote
`controllers according to prior art require troublesome operation or time and effort in
`inputting remote control codes or making settings for manufacturer codes, and therefore
`devices of this type have problems in being difficult to handle by users who are not
`familiar with this type of device.

` First, while the remote control code setting is “setting completed mode” with F=1 set in
`the F-register of RAM 14, if Set key 12e on key input part 12 is operated, the
`aforementioned F-register is set to F=0 to switch to remote control setting mode (Steps
`
`S1 (cid:198) S2 (cid:198) S3 (cid:198) S4).
`
`
`0028
` Alternatively, if Set key 12e on key input part 12 is operated while the remote control
`code setting is “setting mode” with F=0 set in the F-register of RAM 14, the
`aforementioned F-register is set to F=1 to switch to remote control setting completed
`
`mode (Steps S1 (cid:198) S2 (cid:198) S3 (cid:198) S5).
`
`
`0029
` When in remote control setting mode with F=0 set in the F-register of RAM 14, when
`Power key 12a of key input part 12 is operated to turn on the power to an intended
`operating device that is a television receiver of a certain manufacturer, this operation is
`detected in Step S6, and the aforementioned setting mode F=0 is determined in Step S7,
`then manufacturer data N set in the N-register of RAM 14 is updated by [+1] so that if
`manufacturer data N had value N=1 it becomes N=2, and if it was N=2 becomes N=3,
`and thereby the manufacturer designation of the remote control code stored in ROM 13 is
`updated from manufacturer A to manufacturer B, or from manufacturer B to
`manufacturer C (Step S8).
`
`0030
` Then, the power on/off code according to the remote control code corresponding to the
`aforementioned updated manufacturer N is read by CPU 11, and transmitted through
`transmitting circuit 15 from light emitting part 16 as a remote control signal (Step S9).
`
`0031
`
`(cid:56)(cid:81)(cid:76)(cid:89)(cid:72)(cid:85)(cid:86)(cid:68)(cid:79)(cid:3)(cid:53)(cid:72)(cid:80)(cid:82)(cid:87)(cid:72)(cid:3)(cid:38)(cid:82)(cid:81)(cid:87)(cid:85)(cid:82)(cid:79)(cid:3)(cid:3)(cid:40)(cid:91)(cid:75)(cid:76)(cid:69)(cid:76)(cid:87)(cid:3)(cid:20)(cid:19)(cid:19)(cid:23)(cid:3)(cid:3)(cid:51)(cid:68)(cid:74)(cid:72)(cid:3)(cid:20)(cid:19)
`
`

`
` Thus in remote control setting mode, whereby F=0 is set to the F-register of the
`aforementioned RAM 14, each time Power key 12a on key input part 12, the power code
`of different manufacturers in sequence is read from ROM 13 and transmitted, and
`therefore once the power to the intended operating device is turned on, the manufacturer
`data N corresponding to said intended operating device at that time is set in the N-register
`of said RAM 14.
`
`0032
` Here, when Set key 12e of key input part 12 is operated, F=1 is set in the F-register
`resulting in setting completed mode, and the manufacturer data value stored in the N-
`
`register (for example N=2) is confirmed (Steps S2 (cid:198) S3 (cid:198) S5).
`
`
`0033
` Once this is done, thereafter the remote control code(s) read from ROM 13 will be
`code(s) corresponding to the manufacturer data N=2 (manufacturer B) set in the
`aforementioned N-register.
`
`0034
` Accordingly, thereafter whenever Power key 12a is operated and setting completed
`mode F=1 is detected in Step S7, [processing] moves forward to Step S10 and the power
`code for manufacturer B corresponding to manufacturer data N=2 set in the
`aforementioned N-register is read by CPU 11 and transmitted, and the power on/off
`[function] of a television of manufacturer B is remotely controlled.
`
`0035
` Also, if the Up key 12b or Down key 12c for volume adjustment, or channel select key
`12d are operated, setting completed mode F=1 is confirmed in S11, and then in Step S12
`the volume adjustment code for “Up” or “Down,” or channel select code “C1” or C2” etc.
`for Company B corresponding to manufacturer data N=2 set in the aforementioned N-
`register are read by CPU 11 and transmitted, and the volume or channel of a television of
`Company B is remotely controlled.
`
`0036
` Thus in a remote control device according to the first preferred embodiment having the
`aforementioned composition, remote control codes of each of a multiplicity of
`manufacturers are previously stored in ROM 13, and in remote control mode with F=0 set
`in the F-register of RAM 14, the manufacturer data set in the N-register is updated
`sequentially with each operation of Power key 12e [[TN: should be 12a??]] to N=1
`(Company A), 2 (Company B), 3 (Company C)… in response to operation of Set key 12a
`[[TN: should be 12e??]] of key input part 12, and the power code corresponding to said
`updated manufacturer data N is read from said ROM 13 and transmitted as the remote
`control signal, and thereby at a time when power to the intended operated device is
`switched on by means of operation of said Power key 12a, manufacturer data N
`corresponding to the intended operated device is set in the aforementioned N-register,
`and thereafter remote control signals of that manufacturer are is output in response to key
`operations, with the result that
`
`(cid:56)(cid:81)(cid:76)(cid:89)(cid:72)(cid:85)(cid:86)(cid:68)(cid:79)(cid:3)(cid:53)(cid:72)(cid:80)(cid:82)(cid:87)(cid:72)(cid:3)(cid:38)(cid:82)(cid:81)(cid:87)(cid:85)(cid:82)(cid:79)(cid:3)(cid:3)(cid:40)(cid:91)(cid:75)(cid:76)(cid:69)(cid:76)(cid:87)(cid:3)(cid:20)(cid:19)(cid:19)(cid:23)(cid:3)(cid:3)(cid:51)(cid:68)(cid:74)(cid:72)(cid:3)(cid:20)(cid:20)
`
`

`
`it is extremely simple to transmit remote control codes corresponding to the intended
`operated device even without having knowledge related to a device of this type
`
`0037
` Figure 5 is a block diagram showing the composition of a remote control device
`according to a second preferred embodiment of the present invention. Said remote control
`device is provided with CPU (central processing unit) 21.
`
`0038
` Said CPU 21 is connected to key input part 22, ROM 23, RAM 24, and through
`transmission circuit 15 to light emitting part (LED) 16. The aforementioned CPU 11
`[[TN: should be CPU 21??]] activates a system program(s) previously stored in ROM 23
`and [thereby] performs control of operation of various parts according to a key input
`signal from key input part 22, and therefore key input part 22 is provided with Power key
`22a operated when performing power on/off operation to an intended operated device, as
`well as Up key 22b and Down key 22c for volume control, channel select key 22d, Set
`key 22e operated when switching remote control code setting modes, and TV key 22f,
`VTR key 22g, CD key 22h, BS key 22i, and Tape key 22j etc. operated when selecting
`the t
