Abstract: A portable egg candling and containment transfer apparatus including a movable base, a frame extending up from the base, a movable elevator deck movable between an elevated position and a lowered position, and a mechanism for raising and lowering the elevator deck. The apparatus further includes an inverting candling table pivotally mounted to the frame and having a pan with sidewalls and a floor. The pan is adapted for receiving and supporting incubator trays thereon. The pan houses at least one electric light fixture with at least one lamp for producing light for candling eggs positioned over the inverting candling table. The apparatus further includes at least one clamp for securing a hatchery basket over the pan and at least one latch for securing the inverting candling table in faceup/facedown positions.

Abstract: The present invention relates to a densitometry device that can perform suitable densitometry with minimum required light amounts and can achieve space savings. An angle ? between a reference optical axis of a light source, which is an LED chip, and an optical axis, according to a photoelectric conversion element, of a density measurement optical system is set to, for example, 52°. Light-emitting chips, which emit each of red, green and blue light, are provided inside a cannon shell-shaped light-emitting portion. These light-emitting chips are arranged in a straight line along a direction of conveyance of a color patch chart. Consequently, inclination angles of the light-emitting chips with respect to a measurement axis of the density measurement optical system will always change consistently with each other, and no difference between the inclination angles of the different colors will occur.
