摘要： An interchangeable lens is removably attached to a camera body including a body-side mount, an image sensor, body-side terminals and a first to fourth body-side claws. The interchangeable lens includes the lens-side mount, lens-side terminals which are in contact with body-side terminals, a first to fourth lens-side claws engaged with the first to fourth body-side claws once the interchangeable lens is attached to the camera body. The first and third lens-side claws are disposed on a third lens-side line intersecting with the first lens-side line at an optical axis with approximately 45 degrees. The first lens-side line passes through a center between opposite ends of the first lens-side claw to the optical axis. The second and fourth lens-side claws are disposed on a fourth lens-side line orthogonal to the third lens-side line at the optical axis.

摘要： A zoom optical system comprises a first lens group having a positive refractive power, a second lens group having a negative refractive power, a third lens group having a positive refractive power, and a succeeding lens group, which are arranged in order from an object side. During zooming, distances between adjacent said lens groups change. The succeeding lens group comprises a first focusing lens group having a negative refractive power which is moved during focusing, and a second focusing lens group having a positive refractive power which is moved during focusing, which are arranged in order from an object side. Further, the following conditional expression is satisfied: 0.80

摘要： An object of the present invention is to provide a fluidic device in which a solution can be introduced into a flow path and be quantified while preventing air bubbles from being generated.
A pair of substrates are provided which are stacked in a thickness direction and in which one substrate includes a flow path constituted by being covered by another substrate. The flow path includes a quantification part that is able to quantify a solution to a predetermined amount. The quantification part includes: a pair of merging/branching portions each of which is surrounded by a contour that matches each of line segments connecting apex positions of an equilateral triangle in a view of the thickness direction or a contour parallel to each of the line segments and at which merging or branching of the solution is performed; and a connection portion that connects the pair of merging/branching portions via one of the apex positions of the equilateral triangle of the merging/branching portion. A valve which regulates a fluid flow in the flow path is provided at the apex position in the merging/branching portion at which the connection portion is not arranged.

摘要： When the amplification ratio is low and strong incident light causes a large charge, the signal retrieved from regions where the incident light is weak is also weak, but when the amplification ratio is high in regions where the incident light is weak, the signal retrieved from regions where the incident light is strong becomes saturated. Therefore, the dynamic range of the imaging unit is narrow. Provided is an imaging unit comprising an imaging section that includes a first group having one or more pixels and a second group having one or more pixels different from those of the first group; and a control section that, while a single charge accumulation is performed in the first group, causes pixel signals to be output by performing charge accumulation in the second group a number of times differing from a number of times charge accumulation is performed in the first group.
