Title:
MULTI-OPTICAL AXIS PHOTOELECTRIC SENSOR
Document Type and Number:
WIPO Patent Application WO/2011/013510
Kind Code:
A1
Abstract:
A multi-optical axis optical unit is provided in each of the casings of a projector and an optical receiver of a multi-optical axis photoelectric sensor. Each multi-optical axis optical unit includes a shield member (support frame 4) where a plurality of flexible wall portions (41A, 41B) are arrayed on the side edges of a plate base (42), a plurality of fixing holders (5) which have insulation properties and are fitted between the wall portions (41A, 41B) opposed to each other by sandwiching the base (42), a plurality of optical modules (3) supported by the fixing holders (5), and a strip-shaped conductive member (flat cable 6) held between each fixing holder (5) and each optical module (3) on the upper surface of the base (42) of the shield member and electrically connected to each optical module (3). Wall portions (41A, 41B) in positions where a fixing holder (5) and optical module (3) are arranged hold the optical module (3) cooperatively with the fixing holder (5). On the other hand, wall portions (41A, 41B) in positions where no fixing holder (5) and optical module (3) are arranged are bent inward to shield the conductive member.
