The lighting of the LED 18 can be controlled by the microcomputer 32. The alarm device 37 can control the volume of the alarm sound to be output and the pitch at which the alarm sound is output, based on a signal from the microcomputer 32. The threatening means is constituted by the LED 18 and the alarm 37.

Next, the operation of the keyhole lock device configured as described above will be described with reference to the flowcharts shown in FIGS. In a state where the security is released, the shutter 17 is located at the open position.
The ignition key 15 is inserted into the keyhole 16. When the ignition key 15 is turned to the “LOCK” position, the ignition key 15 can be pulled out from the keyhole 16. And ignition key 1
When 5 is removed from the keyhole 16, a signal notifying that the ignition key 15 has been removed is transmitted from the ignition key switch 14 to the microcomputer 32. Based on this signal, the keyhole lock device 13 enters the security state. Specifically, the blinking of the LED 18 is started, and an alarm sound is output from the alarm device 37 at predetermined intervals (step S1). Further, the shutter driving device 36 is driven, and the shutter 17 is rotated from the open position to the closed position covering the keyhole 16.

When the ignition key 15 is in the keyhole 16
After a predetermined time has passed after the
In 2), the microcomputer 32 determines whether or not the shutter 17 has been rotated to the closed position based on a signal from the shutter position detecting device 39 (step S3). If the shutter drive device 36 breaks down or any object
If the shutter 17 has not been turned to the closed position due to circumstances such as being caught by the microcomputer 7, an error signal is transmitted from the antenna 35 of the keyhole lock device 13, and the microcomputer 32 once ends the processing here ( Step S
4). When the error signal is received by the antenna 25 of the remote control key 20, a predetermined error alarm ("error occurrence" in this embodiment) is output from the audio output device 27.

In step S3, when it is confirmed that the shutter 17 has been turned to the closed position, the antenna 35
Outputs a security-on notification signal (step S5). This security ON notification signal is transmitted to the antenna 25
, A predetermined security-on notification voice (“security-on” in this embodiment) is output from the voice output device 27.

Next, the microcomputer 32 determines whether or not the security release signal including the predetermined ID code has been received by the receiving circuit 31 (step S6). The security release signal is transmitted from the transmission circuit 24 when the push button switch 21 of the remote control key 20 is operated.
When the security release signal is not received, or when the ID code included in the security release signal does not match the ID code preset in the microcomputer 32, the keyhole lock device 13 remains in the security state.

Next, it is detected by the light reflection type sensor 38 whether or not an object such as a person has approached the ignition key switch 14 (step S7). Then, when an object such as a person approaches the ignition key switch 14, the keyhole lock device 13 enters a warning state (step S).
8). Specifically, the volume of the alarm sound output from the alarm 37 is increased, and the pitch at which the alarm sound is output is reduced. Also, the blinking speed of the LED 18 increases. This warning state is continued while the object is detected by the light reflection type sensor 38 (step S9). When the object is no longer detected by the light reflection type sensor 38, the security state is returned to the original security state again from the warning state (Step S).
10), and return to step S6. Specifically, the alarm 37
The volume of the alarm sound output from the speaker decreases and returns to the original volume, and the pitch of the alarm sound increases and returns to the original length. In addition, the blinking speed of the LED 18 decreases and returns to the original speed.

Further, in step S6, a security release signal including a predetermined ID code is received by the receiving circuit 31, and the ID code included in the security release signal and
When the ID code matches the ID code preset in the microcomputer 32, the security state of the keyhole lock device 13 is released. Specifically, the blinking of the LED 18 is stopped, and the output of the alarm sound from the alarm device 37 is stopped (step S11). Also, the shutter 17
The shutter is rotated from the closed position to the open position by the shutter driving device 36.

After the push button switch 21 is operated,
After a predetermined time has elapsed (step S12), the microcomputer 32 determines whether or not the shutter 17 has been turned to the open position based on a signal from the shutter position detecting device 39 (step S13). If the shutter 17 has not been rotated to the open position due to a failure of the shutter driving device 36 or a situation where an object is caught on the shutter 17, an error signal is transmitted from the antenna 35 of the keyhole lock device 13. Then, the microcomputer 32 temporarily ends the processing here (step S14). When the error signal is received by the antenna 25 of the remote control key 20,
A predetermined error alarm (“error occurred” in this embodiment) is output from the audio output device 27.

In step S13, when it is confirmed that the shutter 17 has been turned to the open position, the antenna 3
5 outputs a security release notification signal (step S15). When the security release notification signal is received by the antenna 25, a predetermined security release notification sound (“released” in this embodiment) is output from the audio output device 27. In a state in which the security is released, the alarm 37 does not output an alarm sound even when an object approaches the ignition key switch 14, and the ignition key 15 is normally inserted into the keyhole 16.

After the security release notification signal is output, if a predetermined time (30 seconds in this embodiment) has elapsed while the ignition key 15 is not inserted into the keyhole 16 (step S16) (step S1).
7), the keyhole lock device 13 returns to the security state again (step S18), and returns to step S6.

According to this embodiment, the following effects are obtained. (1) Keyhole 1 of ignition key switch 14
With the ignition key 15 removed from the keyhole 6, the keyhole lock device 13 enters the security state, and the keyhole 16 is covered by the shutter 17.
The LED 18 blinks or an alarm sound is output from the alarm device 37. Therefore, a person who intends to steal the scooter 11 must be forced to move the shutter 17 to operate the ignition key switch 14, and is actively threatened with sound or light. Therefore, the possibility that the scooter 11 is damaged when the shutter 17 is forcibly moved can be reduced. As a result, the anti-theft effect of the scooter 11 can be enhanced.

(2) When an object approaches the vicinity of the ignition key switch 14 in the security state, the keyhole lock device 13 enters a warning state, and the volume of the alarm sound output from the alarm 37 is increased. Also, LE
The blinking speed of D18 increases. For this reason, when a person trying to steal the vehicle approaches the ignition key switch 14 to operate the ignition key switch 14, the person trying to steal can be warned by a sound whose volume has increased, You can be more intimidating. In addition, it is possible to make surrounding people think that an abnormal situation such as the scooter 11 is about to be stolen has occurred, and it is possible to make it more difficult for a person who intends to steal the scooter 11 to steal. . Therefore, scooter 1
1 can be less likely to be damaged,
As a result, the anti-theft effect of the scooter 11 can be further enhanced.

(3) When the remote control key 20 is operated and a security release signal is output, the shutter 17 is moved from the position covering the keyhole 16 to the open position, so that an alarm sound is output from the alarm 37 and the LED 18 is turned off. Flashing stops. When the keyhole 16 is opened and the stop of the alarm 37 and the LED 18 is confirmed, a predetermined sound (“canceled”) is output from the sound output device 27 of the remote control key 20 (answer-back function). ). For this reason, the driver who operates the remote control key 20 opens the keyhole 16 and simultaneously outputs the alarm 37 and the LED 18.
Can be easily and reliably confirmed by voice. Accordingly, the driver can easily and reliably release the security even from a position where the shutter 17 is not visible, without leaving the scooter 11 and not having to worry about the alarm 37 or the LED 18.

(4) The keyhole 16 of the ignition key switch 14 is covered by the shutter 17 within a predetermined time after the ignition key 15 is removed. Therefore, the shutter 17 for preventing tampering such as insertion of a stick into the keyhole 16 can be easily and reliably turned to the closed position without performing any other operation only by pulling out the ignition key 15.

(5) Even if a predetermined time has elapsed after the ignition key was removed, the sound output device 27
If the key 7 has not been moved to the closed position covering the keyhole 16, a predetermined sound ("error occurred") is output. Therefore, the shutter driving device 36 may fail or the shutter 1
If the shutter 17 is not moved to the closed position due to any object being caught on the driver 7, the driver having the remote control key 20 can be reliably notified.

(6) Since the remote control key 20 is formed separately from the ignition key 15, it can be retrofitted to the ignition key 15 as a key holder. Therefore, the remote control key 20 can be easily combined with the existing ignition key 15.

The embodiment is not limited to the above-described embodiment, and may be modified as follows, for example. The LED 18 and the alarm 37 are not necessarily attached to the keyhole lock device 13, but only one of them may be attached. For example, only the LED 18 may be attached. Further, for example, only the alarm 37 may be attached. It is desirable to attach the alarm 37.

The alarm 37 does not output an alarm sound when the light reflection type sensor 38 does not detect the approach of the object even in the security state, and outputs an alarm sound only when the approach of the object is detected. May be set. In this case, the power consumption of the battery can be reduced.

The number of LEDs 18 is not limited to one, but may be plural. And when the warning action is activated,
The setting may be made so that the number of lit LEDs increases. The alarm sound output from the alarm 37 is not limited to the sound output at a predetermined interval, and may be a continuous sound.

The keyhole lock device 13 has an alarm 3
For example, an audio output device may be attached. This audio output device outputs, for example, sounds such as "warning" and "stolen" at predetermined intervals.

The remote control key 20 includes the audio output device 2
For example, a vibration generating device may be built-in. Then, the driver may be notified of security release or occurrence of an error by the vibration generated by the vibration generating device. It is desirable that the vibration generator generates different vibration modes in response to security release and error occurrence.

The remote control key 20 includes the audio output device 2
7 and a vibration generator. The remote control key is not limited to being configured separately from the ignition key 15; for example, the ignition key 1
5 may be integrally formed.

The sound output from the sound output device 27 is not limited to "canceled", "error occurred", and "security on". It may be audio.

The sound output device attached to the remote control key 20 is not limited to the sound output device 27, but may be, for example, a buzzer. The shutter 17 is not limited to the configuration in which the shutter 17 is rotated between the closed position and the open position by the shutter driving device 36.
It may be configured to be movable between a closed position and an open position by manual operation. Then, even if the lock is automatically released by the engagement means or the like when moved to the closed position, the engagement means is released by operating the button switch 21 of the remote control key 20, and the lock is released. Good.

The keyhole lock device 13 is limited to such a state that the shutter 17 is moved to the closed position only by pulling out the ignition key 15 from the keyhole 16, and the security state is set such that the LED 18 blinks. I can't. For example, when the ignition switch 15 is pulled out of the keyhole 16 and the button switch 21 is operated, a predetermined signal is transmitted from the transmission circuit 24 of the remote control key 20, and the shutter 17 is moved to the closed position to release the key. The hole lock device 13 may be set to be in a security state.

The keyhole lock device 13 is used to change the light and sound output from the LED 18 and the alarm 37 depending on whether or not an object such as a person is approaching the ignition key switch 14. Without limitation, for example,
Light or sound may always be output at a constant blinking speed or volume regardless of the approach of an object such as a person. In this case, the light reflection type sensor 38 need not be attached.

The anti-theft device of the present invention is not limited to being mounted on a scooter, but may be mounted on another motorcycle. Also, the present invention is not limited to motorcycles, and may be attached to, for example, a motorcycle having two rear wheels.
