Therefore, before using the portable transmitter 40 and the receiver 50, the user registers the ID code in the ID code storage unit 45 of the portable transmitter 40,
It is necessary to store the reference (ID) code in the receiver 50 using the portable transmitter 40 in which the ID code is registered.

FIG. 6 shows the portable transmitter 4 shown in FIG.
FIG. 4 is an explanatory diagram showing an example of an operation procedure when registering an ID code in the ID code storage unit 45 at 0.

The operation of registering an ID code in the ID code storage unit 45 of the portable transmitter 40 will be described with reference to the explanatory diagram shown in FIG.

The user performs a predetermined operation using one or more operation switches of the operation switch unit 1 of the portable transmitter 40;
For example first operates the trunk opening switch 1 _3, together with the trunk opening switch 1 ₃ and the operation is performed within 100 milliseconds of the door lock switch 1 ₁ is operated for more than one second, then the trunk opening switch 1 ₃ performs a predetermined operation for stopping the operation of the door lock switch 1 _1, the mode control unit 42 ₃ detects that the predetermined operation is performed, it sets the control unit 42 to the ID registration mode. Control unit 4
When 2 enters the ID registration mode, after performing the reset of the counter 42 _6, a clock signal generator 42 ₅ starts first time count of the clock signal supplied from the display unit 45 from the mode control unit 42 ₃ The first pulse signal is supplied to one of the LEDs, for example, a red LED. Red LED
Is illuminated a plurality of times at 200 millisecond intervals at 500 millisecond intervals by the supply of the first pulse signal to inform the user that the portable transmitter 40 has entered the ID registration mode. Note that the intermittent lighting of the red LED continues while the portable transmitter is in the ID registration mode.

[0015] Then, the user, who switches operated later of the operation switch unit 1 of the portable transmitter 40, for example, a door lock switch 41 ₁ to operate more than 100 milliseconds,
If you stop the operation of the door lock switch 41 _1, the other LED of the display unit 45 from the ID code generating unit 42 _4, for example, the second pulse signal is supplied to the green LED, the green LED just once lit 500 milliseconds. And green LED
When the lighting of is completed, the counter 42 ₆ at determined that the first counting value of the clock signal, determined the count value is supplied to the RAM47 constituting a temporary storage unit. At this time, the counter 42 ₆ is reset, followed by a count of the second clock signal starts, the first pulse signal from the ID code generating unit 42 ₄ red LED is supplied a plurality of times as before, the red LED Lights up intermittently.

Next, the user operates the door lock switch.
41₁ After operating again for more than 100 milliseconds,
Switch 41₁ When the operation of is stopped, the ID code generator
42 _Four Again supplies the second pulse signal to the green LED.
The green LED is turned on only once for 500 milliseconds. So
When the green LED is turned off,
TA 42₆ Second count value of the clock signal at
Is determined, and the determined count value is supplied to the RAM 47.
You. At this time, the counter 42₆ Reset and continue
And start the third clock signal counting,
The LED lights up intermittently.

[0017] Then, the user, after operating the door lock switch 41 ₁ thrice beauty 100 milliseconds or more, when stopping the operation of the door lock switch 41 _1, the second pulse from the ID code generating unit 42 ₄ green LED Signal is supplied,
The green LED is lit once for one second longer than the previous two. When the lighting of this green LED is completed, the counter 42 ₆ in established third time the count value of the clock signal, the count value is that determined RAM47
Is supplied to the next the three count values are read from the RAM 47, it is registered are combined in the ID code storage unit 44 _1.

In this case, the 3
One count value is divided and stored in three areas of 8 bits each, and each area has 00000000
One of the 256 data values from to 111111111 is stored.

The count of the first clock signal counter 42 ₆ is performed after being reset from 00000000 to every application of the clock signal 11111111
Until it reaches 111111111, and after that it reaches 000
It returns to 00000 and changes toward 11111111 again. Then, 1 from the count value of the counter 42 ₆ when the lighting of the first green LED is completed RAM47
Is stored in the second area.

[0020] Thereafter, the count of the second and the third clock signal counter 42 ₆ is performed after being reset also, the same as that described above, the second green LE
The count value of the counter 42 ₆ when D lit is completed, the second area of the RAM 47, the third green L
The count value of the counter 42 ₆ when the lighting of the ED has been completed, are respectively housed in the third area of the RAM 47.

As soon as the count value is stored in each of the three areas of the RAM 47, the ID code generator 42 ₄
Reads these count values from the RAM 47, and
The ID code is synthesized by combining it with a code of continuous bits, and I
Registered in the D code storing unit 44 _1.

As described above, the count value stored in the RAM 47 is set at random according to the operation timing of the switch performed by the user, and the set value cannot be arbitrarily selected. Therefore, the probability that the ID code registered in the portable transmitter 40 and the ID code registered in the other portable transmitter match each other is extremely small, and the incompatible portable transmitter is not provided. Is obtained.

When ten seconds have passed since the control unit 42 entered the ID registration mode, the portable transmitter 40 automatically returns from the ID registration mode to the normal mode. Flashing of the red LED ends.

As shown in FIG. 6, when the third count value is determined, the third lighting of the green LED is completed, and the registration of the ID code is completed, the control unit 42
Returns from the ID registration mode to the normal mode even before 10 seconds have passed since the ID registration mode was entered.

Next, FIG. 7, when registering an ID code in the ID code storage unit 44 ₁ of the portable transmitter 40 is an operation explanatory view showing an example of a case that can not be registered ID code.

The operation when the ID code cannot be registered will be described with reference to FIG.

As shown in FIG. 7, the operation procedure until the control unit 42 of the portable transmitter 40 enters the ID registration mode is the same as the operation procedure shown in FIG. 6 already described.

The user switches operated later of the operation switch unit 1 of the portable transmitter 40, for example, a door lock switch 41 ₁ ends its operation after operating more than 100 milliseconds, ID code generating unit 42 ₄ To display unit 4
The second pulse signal is supplied to the green LED 5 and the green LE
D is lit for 500 milliseconds. When the lighting of the green LED is terminated, the counter 42 ₆ of the first time count value determined in the clock signal, determined the count value is supplied to the RAM 47. At this time, the counter 42 ₆ is reset and subsequently the count of the second clock signal and start, the red LED is intermittently turned on.

[0029] After that, the user switch that was operated from the rear of the operation switch unit 1 of the portable transmitter 40, for example not operate the door lock switch 41 _1, 10 seconds from the control unit 42 is entered into the ID registration mode After the elapse, the control unit 42 automatically returns from the ID registration mode to the normal mode. In this case, only the count value of the first time is determined, since the second time and the count value of the third is not established, ID code generating unit 42 _4, RAM 47
The first time the count value disposal, is not carried out the ID code storage unit 44 ₁ in the registration of ID codes stored in the.

The unregistered status of the ID code into the ID code storage unit 44 _1, after the first round and the second round of the count value has been determined, automatically control unit 42 from the ID registration mode to the normal mode The same applies when returning.

If you stop the operation of the door lock switch 1 ₁ before the lapse of 10 seconds from, is supplied determination signal from the counter 2 ₆ to the time extension 2 _7, whereby for the time extension 2 ₇ controller 2 The ID registration mode setting time is extended by a fixed time, for example, 10 seconds.
At the same time, ID other LED of the display unit 5 from the code generator 2 _4, for example, the second pulse signal is supplied to the green LED, the green LED is lit once 500 milliseconds.
When the green LED is turned off, the counter 2
_6. The first count value of the clock signal performed in step ₆ is determined, and the determined count value is set to R
AM7. At this time, the counter ₂₆ is reset, and then starts counting the second clock signal. The first pulse signal is before and supplied a plurality of times in the same manner from the mode control unit 2 ₃ a red LED, a red LE
D lights up intermittently.

[0063] Next, the user stops the operation of the door lock switch 1 ₁ before the door lock switch 1 ₁ is operated again 100 milliseconds or more, the passage of 10 seconds from the previous operation at the end of the door lock switch 1 ₁ then, it is supplied again confirm signal to the time extension unit 2 ₇ from the counter 2 _6, whereby the time extension 2 ₇ again certain time the ID registration mode setting time to the control unit 2, for example, extended by 10 seconds. At the same time, the green from the ID code generating unit 2 ₄ LE
The second pulse signal is supplied to D again, and the green LED is turned on only once for 500 milliseconds. And this time green LE
When the lighting of D is completed, the second count value of the clock signal performed by the counter ₂₆ is determined, and the determined count value is supplied to the RAM 7. At this time, the counter ₂₆ is reset, and subsequently starts counting the third clock signal. Again, the red LE
The first pulse signal is supplied to D, and the red LED lights up intermittently.

[0064] Then, the user, after operating the door lock switch 1 ₁ thrice beauty 100 milliseconds or more, when stopping the operation of the door lock switch 1 _1, the from the ID code generating unit 2 ₄ green LED 2 A pulse signal is supplied to illuminate the green LED for one second, one time longer than the previous two times.
Then, when the current lighting of the green LED ends, the third count value of the clock signal performed by the counter ₂₆ is determined, and the determined count value is supplied to the RAM 7.

[0065] Then, ID code generating unit 2 _4, RAM
7 is supplied with the first, second, and third count values, the count values are combined and stored in the storage unit (EEPR).
Is registered as the ID code in the ID code storage unit 4 ₁ OM) 4. Thereafter, the control unit 2 automatically returns from the ID registration mode to the normal operation mode.

[0066] Also in this embodiment, the ID code registered in the ID code storage unit 4 _1, as described above 24
The count value stored in the RAM 7 is divided and stored in the first, second, and third areas in units of 8 bits.

[0067] Incidentally, as shown in FIG. 2, the time period extension 2 ₇ to extend the ID registration mode setting time to the control unit 2, but those are preferably respectively approximately 10 seconds In particular, the time is not limited to 10 seconds, and a time of about 10 seconds may be appropriately selected.

[0068] Also in this embodiment, the ID code registered in the ID code storage unit 4 ₁ is set randomly by the operation timing of the switch performed by a user, which can not be selected the setting state arbitrarily It is. Therefore, the probability of the ID code registered in the ID code storage unit 4 ₁ of ID code and other portable transmitter 10 to be registered in the ID code storage unit 4 ₁ of the portable transmitter 10 coincides very small Thus, a portable transmitter 10 having no compatibility can be obtained.

[0069] Next, FIG. 3, the portable transmitter 10 illustrated in FIG. 1, is a diagram illustrating an example of an operation procedure for erasing the ID code registered in the ID code storage unit 4 ₁ .

[0070] Using the illustration shown in FIG. 3, for explaining the operation when erasing the ID code registered in the ID code storage unit 4 ₁ of the portable transmitter 10.

The user (operator) operates the portable transmitter 10
Using one or more operation switches of the operation switch section 1
A predetermined second predetermined operation, for example, first the trunk
Open switch 1_Three , And after this operation is performed, 1
Trunk open switch 1 within 00 ms_Three With door
Lock switch 1₁ To perform these operations.
Open switch 1 within 100 ms_Three as well as
Door lock switch 1 ₁ With panic switch 1_Four 
For at least one second, and then open the trunk switch.
Chi 1_Three , Door lock switch 1₁ , Panic switch 1
_Four When the second predetermined operation for ending the operation is performed, the mode control
Gobe 2_Three Detects that this second predetermined operation has been performed
Then, the control unit 2 is set to the ID erasing mode.

[0072] When the control unit 2 became ID erase mode, one LE of the display unit 5 from the mode control unit 2 ₃
D, for example, a third pulse signal is supplied to a light-colored LED.
The light-colored LED is lit three times at 500 millisecond intervals by supplying the third pulse signal for 500 milliseconds, to notify the user (operator) that the portable transmitter 10 has entered the ID erasing mode. And the third to illuminated LED
At the time the supply of the pulse signal is terminated, the ID erase signal supplied from the ID code erasing section 2 ₈ to the ID code storage unit 4 _1, whereby the ID code registered in the ID code storage unit 4 ₁ is erased . The control unit 2, when the ID code registered in the ID code storage unit 4 ₁ is erased,
It automatically returns to the normal operation mode from the ID erase mode.

As described above, according to the portable transmitter 10 of the present embodiment, it is possible to minimize the possibility that the user cannot register the ID code due to the expiration of the ID registration mode time. Before shipping the portable transmitter 10, the same test ID code was registered for each portable transmitter 10, and an efficient information transmission test was performed between the portable transmitter 10 and the receiver. Thereafter, the registration of the test ID code is deleted by using the ID code erasing means, so that the compatibility between the portable transmitters 10 is increased because the same test ID code is registered after shipment. It is possible to prevent a malfunction from occurring.

In the above embodiment, the ID code is deleted.
One or more operation switches 1 ₁ Or 1_Four Have
Although an example including the operation switch unit 1 has been described,
Unique ID code erase switch as D code erase means
To operate this ID code erase switch.
ID code storage unit 4₁ ID code registered in
May be deleted. However, this ID code
The erasure switch is not normally operated.
Instead of being placed on the surface of the housing of the portable transmitter 10,
It is preferable to arrange them in an inclined state.

The predetermined operation at the time of setting the ID registration mode and the second predetermined operation at the time of setting the ID erasure mode described in the above embodiment are merely examples of the respective operation states. Needless to say, the type and number of switches to be operated, the operation times of the switches, the operation intervals, and the like can be arbitrarily selected.

[0076] Further, in the above embodiment, ID code erasing section 2 _8, ID code generating unit 2 _4, the time extension 2
_{Although 7 and the} like have been described as parts on the block diagram, these parts and other parts may be configured as a part of the program.

[0077] Here, after the ID code in the ID code storage unit 4 ₁ of the portable transmitter 10 is registered, the reference in the reference code storage unit of the receiver using the portable transmitter 10 (I
D) The operation of registering the code is the same as the operation of registering the reference code described above between the portable transmitter 40 and the receiver 50 shown in FIGS. 4 and 5. For this reason, the description of the operation process at the time of registering the reference code in the receiver will be omitted because the description is duplicated.

[0078] Also, the ID code in the ID code storage unit 4 ₁ of the portable transmitter 10 is registered, after the reference code is registered in the reference code storage unit of the receiver, the portable transmitter 10 and receiver The information transmission operation performed between them is the same as the already described information transmission operation performed between the portable transmitter 40 and the receiver 50 shown in FIGS. Therefore, description of information transmission between the portable transmitter 10 and the receiver will be omitted because the description is redundant.
