Description

  The invention of this application is to detect intruders by providing a multi-beam detection unit provided with beam sensor units in a plurality of upper and lower stages and a notification display unit therebetween, and a plurality of multi-beam detection units arranged at appropriate intervals. It is related with the infrared crime prevention apparatus to perform.

  2. Description of the Related Art Conventionally, an infrared security device is known in which a transmitting unit and a receiving unit as a beam sensor unit are arranged to face each other, infrared rays are transmitted and received between them, and infrared rays are detected when they are blocked by an intruder. (For example, refer to Patent Document 1).

  This infrared crime prevention device is, for example, a fence crime prevention device that is attached to an exterior fence installed in a building such as a house, and performs notification or threatening when an intruder gets over the exterior fence to block infrared rays. It is considered that it can be used.

  At this time, the transmitting unit and the receiving unit are arranged back to back to form an integrated detection unit, and a plurality of adjacent detection units are arranged opposite each other along an outer edge of a crime prevention space such as an exterior fence, and adjacent one of them. An infrared crime prevention apparatus having an aspect in which infrared transmission / reception is performed between the transmission unit of the detection unit and the reception unit of the other detection unit can be considered.

  In addition, a double beam system in which a beam sensor unit of a transmission unit and a reception unit is provided in two upper and lower stages, and a multi-beam system having three or more upper and lower stages are also known (see, for example, Patent Document 2). Hereinafter, the upper and lower two or more stages are collectively referred to as a multi-beam system.

  However, in the multi-beam method, there may be a mode in which a notification display unit such as a notification lamp or a threatening lamp is provided between the upper and lower beam sensor units. In this case, however, there is a notification display unit having a display substrate and a display cover. As a result, the substrate for the beam sensor section is divided into upper and lower parts due to the structure, which causes a problem that the number of parts increases and that assembly requires time.

  Therefore, in view of the circumstances as described above, the invention of this application is to provide a beam sensor unit in a plurality of upper and lower stages and provide a notification display unit between them, so that an increase in the number of parts can be suppressed and simple assembly can be performed.
