To enable to display a scale indicative of a reference length on a screen of a display at an accurate length even when exchanging the lens in an image pickup apparatus to any lens. In a case of mounting an exchange lens (F,Z) to an image pickup apparatus main body () and displaying an image of an object picked up by an image sensor () and a scale () indicative of a reference length in juxtaposition on a screen of a display (), a previously measured optical magnification or an actual magnification is outputted from optical magnification outputting means () provided to the exchange lens (F,Z) is outputted, an actual magnification on the screen of the display () is calculated based on the optical magnification, the size for the image sensor and the screen size, and the size of the scale on the screen is set based on the actual magnification and the reference length of the scale by a scale setting means ().

An aligning mechanism having stage mechanisms, each of which is composed of a first stage capable of moving in the direction in which a fiber array b advances to and retreats from a waveguide type optical member a, a holding section sustaining memberfor the fiber array and a second stagecapable of moving in the direction perpendicular to the direction in which the fiber array spreads, wherein angle adjusting mechanismsandcapable rotating around the rotation axis perpendicular to both the said directions are provided between the first and second stages and the holding section sustaining member and the second stage. One aligning unit can be used for aligning either of two fiber arrays and a waveguide type optical member respectively having orthogonally ground end faces or either of fiber arrays and a waveguide type optical member respectively having obliquely ground end faces, and also allows the angle to be easily changed in response to the angle of the end faces.
