  Moreover, in recent years, expensive fruits typified by cherries have been stolen, and it has been desired to develop an alarm device to prevent such damage. It is intended for areas and is not suitable as an alarm device that requires a large security area such as a cherry farm. Many of those who enter the cherries at night, especially at night, are thought to be attempting to steal, but not only to repel them and prevent crimes, but also to prevent recurrence. In addition, it is preferable to install an alarm device that can identify a trespasser and, if necessary, arrest the current criminal. The above-described security alarm device cannot sufficiently satisfy such a demand.

(System configuration)
The system configuration of the present invention is as shown in FIG.
An intrusion detection signal output sensor unit 1, which is a sensor that detects that a person has entered a specific alert area and outputs a detection signal;
A predetermined telephone number is registered in advance, and an automatic transmission to a predetermined telephone number is a device having a function of automatically transmitting a call to the registered predetermined telephone number by short-circuiting two poles in an earphone microphone connector for a predetermined time. Means 2,
A switch circuit 3 formed by connecting an earphone microphone connection plug to the earphone microphone connector of the automatic transmission means 2;
And relay means 4 for activating the automatic transmission function of the mobile phone by closing a switch circuit in response to a detection signal from the sensor means.

The circuit configuration of this device is as shown in FIG.
A commercially available intrusion detection device 10 corresponding to the intrusion detection signal output sensor means 1,
The detection signal output line 12;
A mobile phone 20 capable of one-push dialing (corresponding to automatic calling means 2 to a predetermined telephone number) (a communication terminal such as a PHS having the same function as one-push dialing can be substituted);
A switch 24 corresponding to the switch circuit 3 and extended from an earphone jack for activating an automatic transmission function of the mobile phone 20;
And a relay circuit 30 corresponding to the relay means 4 for operating the automatic transmission function.

(Intrusion detection device)
In this embodiment, as the intrusion detection device 10, a commercially available product corresponding to the above-mentioned Patent Document 1 (“Always Safe” by Optex) is used. This is an intrusion detection device that can obtain a sufficient intimidating effect by generating different alarms at appropriate timing according to the movement of intruders in the alert area, and it detects when intrusion is detected It is a specification to output a signal of +3 V as a signal.

(Mobile phone with automatic calling function)
The mobile phone 20 is a model having an automatic calling function called one-push dialing or hot dialing. This one-push dialing means, for example, that a telephone number to be automatically called is registered in a maximum number of a telephone number list stored in a memory, and a commercially available three-pole type which is connected to an earphone jack of a mobile phone. When the remote switch of the one-push / hot-dial earphone / microphone is continuously pressed down for a predetermined time (for example, 2 seconds or more), this function automatically transmits the registration number. In this apparatus, an earphone microphone connector connected to a switch 24 combined with a relay switch RL1 is used instead of a commercially available earphone microphone with a three-pole one-push hot dial. The earphone microphone connector uses three or four cores, of which two are used.

(Relay circuit configuration)
As shown in FIG. 2, the relay circuit 30 includes a diode D1, a capacitor C, a resistor R, a transistor TR1, a diode D2, and a relay RL1 wired together with the detection signal output line 12 of the intrusion detection device 10, and an automatic transmission function switch. 24 and the relay RL1 are combined.

(Circuit operation transition)
The transition of the operation of the circuit is shown in FIGS.

(Transition 1)
In transition 1 (FIG. 3), the detection signal from the detection signal output line 12 flows to the relay circuit. At this time, a current I1 flows. The current I2 does not flow due to the rectification between the base and the emitter of the transistor TR1.

(Transition 2)
In the transition 2 (FIG. 4), the capacitor C is charged by the current I1 of the transition 1, and at the same time, the current I3 between the base and the emitter of the transistor TR1 flows by the charging.

(Transition 3)
In transition 3 (FIG. 5), the current I3 between the base and the emitter of the transistor TR1 in the transition 2 flows, so that the current I4 between the collector and the emitter flows.

(Transition 4)
In transition 4 (FIG. 6), the current I4 between the collector and the emitter of the transistor TR1 flows, so that the relay switch RL1 is turned on and the current I5 for activating the automatic transmission function switch 24 flows.

  In the state of transition 4, the current I2 from the capacitor C gradually decreases with time, and finally stops flowing. At the same time, the current I4 between the collector and the emitter stops flowing. Accordingly, the relay switch RL1 is turned off, and the current I5 for activating the automatic transmission function switch also stops flowing.

  Note that the maintenance time of the transition state 4 varies depending on the values of the capacitor C and the resistor R, and therefore, it is necessary to set the maintenance time to be equal to a predetermined time for operating the automatic transmission function. FIG. 7 shows the variation of the current continuation time T to the relay RL1 due to the combination of the values of the capacitor C and the resistor R.

(Timing chart)
FIG. 8 shows a timing chart of the relay circuit 30 of the present embodiment in the transitions 1 to 4. It is assumed that the transitions 2 and 3 in FIG. 8 are switched instantaneously, and the maintenance time of the transition state 4 is set to a predetermined time for activating the automatic transmission function, here, about 2 seconds. I have.

(Automatic shooting system)
This system is further provided with a lighting unit 5 and an automatic photographing unit 6, and a system configuration related to these units is shown in FIG. That is, the detection signal output line 12 of the intrusion detection device 10 has a configuration in which the illumination device 100 and the automatic imaging device 110 including the solenoid 114 and the timer 116 are connected in parallel.

(Operating specifications)
When the detection signal flows from the detection signal output line 12 of the intrusion detection device 10, the power of the lighting device 100 is immediately turned on. At the same time, the timer 116 of the photographing device 110 is operated, and after a predetermined time (for example, about one second), the shutter button 112 of the photographing device 110 is pressed by the operation of the solenoid 114, and the photographing device 110 is operated. As a result, the detected intruder is surprised by the light of the AC100V incandescent light bulb, which is the lighting device 100, and immediately turns his / her face, and immediately uses the camera, which is the photographing device 110 arranged near the lighting device 100, to detect the intruder's face.
