本発明は自動車用のドアあるいは１ランク蓋などに設け
る自動車用盗難防止装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an anti-theft device for an automobile provided on an automobile door or a first rank lid.
従来、ドアあるいはトランク蓋などに設けられている錠
をキーで施錠していれば、盗難に対し安全であるが、錠
のロータを抜取るような破綻行為による盗難においては
、これを未然に防止することができないという欠点があ
る。Conventionally, locking a door or trunk lid with a key is safe from theft, but it is possible to prevent theft from occurring through acts of fraud such as removing the rotor of the lock. The disadvantage is that it cannot be done.
そこで、上記問題点を解決するための自動車用盗難防止

を鳴らずのである。Therefore, the applicant has proposed an anti-theft device for automobiles in order to solve the above-mentioned problems in Japanese Patent Application No. 199714/1983. Japanese Patent Application No. Sho 57-199714 is constructed as shown in FIGS. 1 and 2. That is, when the cylinder lock C is pulled out from the switch housing A due to an unauthorized unlocking input, the advancing/retracting rod B advances due to the bias of the spring 14, and the magnet 15 acts as a trigger for the removal detection reed switch 1.
Move to position 6. At this time, the removal detection reed switch 16 is closed, so the alarm device is not activated and the alarm does not sound.

動してアラームを鳴らす。In addition, if the cylinder lock C is displaced and released with a screwdriver or the like without using a regular key and the door etc. is opened, the magnet 20 fixed to the drive cam 19 does not move, so the switch housing A is not opened. The detection reed switch 5 is not closed. In this state, when a door or trunk lid is opened, the open/close detection switch is closed and the alarm device is activated to sound an alarm.
ところが、前記従来例は不正解錠を検知する手段として
磁気感知スイッチを用いているため、強力な磁石を磁気
感知スイッチに近づけると磁気感知スイッチが誤作動を
起こし不正解錠を防止できなくなる恐れがあった。However, since the conventional example uses a magnetic sensing switch as a means of detecting unauthorized unlocking, if a strong magnet is brought close to the magnetic sensing switch, the magnetic sensing switch may malfunction, making it impossible to prevent unauthorized unlocking. there were.

に接続する構成とした。The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to prevent malfunction of an automobile anti-theft device. In order to achieve this object, the present invention provides an anti-theft device that is attached to a cylinder lock and has a σ air sensing switch, in which a malfunction prevention magnetic sensing switch having characteristics opposite to those of the magnetic sensing switch is attached to the magnetic sensing switch. The configuration was such that they were connected in series.
以下、本発明の実施例を添付図面に基づき詳細に説明す
る。Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

じる。In FIGS. 3 to 5, C is a cylinder lock on which a rotor 2 is rotatably provided. A lever L for locking and driving the H lock is provided at the inner end of the rotor 2. A magnet 20 is provided on the drive cam 19 of the lever L seat, and it comes into contact with and separates from the normally open unlock detection reed switch 5 (magnetic sensing switch) installed in the switch housing A1, and when the lever L is unlocked, Then, the reed switch 5 is closed.
