Problems solved by technology

[0034] However, according to the photoelectric separation type detector of Patent Document 4, since the cover is held at the lower part of the main body, the cover blocks the field of vision when viewed from below during installation work, making it difficult to see the inside of the main body, and there is a problem that workability such as wiring connections is poor.
In particular, this problem is more prominent when the wiring part is located in the lower part of the main body

Embodiment Construction

[0062] Mainly based on Figure 1 to Figure 10 , In addition, the photoelectric separation type detector 1 according to one embodiment of the present invention will be described with reference to other drawings as necessary.

[0063] Such as figure 2 As shown, the photoelectric separation detector 1 is composed of light-emitting elements 21 (refer to image 3 ) The light transmitter 3 of the optical bench 23 and the light receiver 5 having the optical bench 23 accommodating the light receiving element 22 are arranged oppositely in the monitoring space. In addition, the light transmitter 3 and the light receiver 5 have basically the same structure except for the light emitting element 21, the light receiving element 22 and their related circuits, so the following description will take the light transmitter 3 as an example.

[0064] Such as figure 1 , Figure 3 ~ Figure 6 As shown, the light sender 3 includes: a main body 13 with a substantially L-shaped L-shaped member 7 an...

Abstract

The present invention provides a photoelectric separation type detector. The light transmitter (3) and the light receiver (5) of the photoelectric separation type detector (1) comprise a main body (13) provided with an optical base (23) and a base (15) fixed to the wall surface side of a building and used for setting the main body (13), and a temporary setting portion (45) is provided in the lower portion of the main body (13), a temporary setting portion (45) is detachably clamped on a locking spring (35) for temporarily holding the main body (13), and the locking spring (35) is provided at the upper portion of the base (15). Thereby the photoelectric separation type detector has a good workability at the time of setting.

Description

[0001] This application is a divisional application of a patent application with an application date of August 6, 2013, an invention titled "photoelectric separation detector", and an application number "201310339348.9". technical field [0002] The present invention relates to a photoelectric separation type detector configured by arranging a light transmitter having an optical bench accommodating a light-emitting element and a light receiver having an optical bench accommodating a light-receiving element facing each other in a monitoring space. Background technique [0003] In the photoelectric separation type detector, the light transmitter containing the light emitting element and the light receiver containing the light receiving element are arranged facing each other at a monitoring distance of 5 to 100 m at a high place (usually 10 to 15 m above the ground). The photoelectric separation type detector detects fire by detecting the attenuation of light due to the presence...
