Abstract:
1. A portable gas detector comprising: a housing shaped as a slim and substantially flat box that is adapted to be grasped by a user's hand, said housing including a functional part region, in which functional members related to a gas detecting operation are arranged, at a fore-side of the housing, and a battery part region, in which a power source for driving the functional members is arranged, at a rear portion of the housing; a plurality of gas sensors arranged in an L-shape, in the functional part region, such that one of the sensor is provided at a corner of the L-shape and such that a plurality of gas sensors are provided in each of two extending portions of the L-shape that. extend from the corner; a gas suction mechanism which sucks gas from outside of the gas detector into the housing to be exposed to the gas sensors, and which is provided in a space at an interior of the L-shape such that the space is bordered on two sides by the two extending portions of the L-shape; and a sensor cap which covers the sensort and which comprises a gas flowing path extending therethrough, a plurality of gas inlet passages corresponding respectively to the gas sensors to expose the gas sensors to the gas traveling through the gas flowing path, and an input section through which the gas sucked into the housing is input to the gas flowing path.
