Abstract: An electronic device includes a housing body, a dividing member that divides the housing body into a first compartment and a second compartment, a sealing member that divides the first compartment into a liquid-stopper region and an exterior communication region, one or more heat emitting components disposed in the liquid-stopper region, a fan disposed in the exterior communication region, and a ventilation pathway through which an airflow passes through the dividing member to the second compartment due to driving the fan.

Abstract: A measuring device includes an actuator which holds a lens unit and moves the lens unit in the direction of the optical axis thereof. A test chart is photographed, with the lens unit being opposed to a reference image pickup device, and the lens unit is positioned at a just-focus position. The gap between the reference image pickup device and the lens unit at this time is reproduced, and an image pickup device, which is to be integrated, and the lens unit are opposed with this gap, and are fixed.

Abstract: A holding fixture that holds a component and mounts the component on an electronic circuit board includes a holding member that holds the component at a side of a first surface of the electronic circuit board, a first fixing member that includes a first base that is engageable with the holding member, and an elastic member that is pivotally attached to the base, sandwiches the electronic circuit board at a side of a second surface of the electronic circuit board, and elastically supports the holding member at the side of the first surface, the second surface opposing to the first surface, and a second fixing member that includes a second base that is engageable with the holding member, and a projection member that projects from the second surface of the electronic circuit board and is engageable with the elastic member.
