A planar illumination device 10 is provided with a laser light source 11 for emitting laser light, a light source side bundle fiber 12 having one end surface thereof optically connected with the laser light source 11, a flat light guide plate 13, a plurality of connection side fibers 16 planarly arranged in parallel with each other at a side surface of the light guide plate 13, and a light guiding fiber 14 for guiding the laser light from the light source side bundle fiber 12 to the plurality of connection side fibers 16. The laser light is incident on the side surface of the light guide plate 13 from the plurality of connection side fibers 16 via a plurality of fiber collimators 17 and output light is uniformly emitted from one principal surface of the light guide plate 13.

A light guide body is arranged and light emerging from the light guide body is made incident on a light guide plate. The light guide body is formed to introduce the incident light to the light guide plate in such a manner that the light incident on an end surface of the light guide plate has a specified light quantity distribution.

A laser light source (1) emits a beam. A collimator lens (2) converts the beam emitted from the laser light source (1) into first substantially parallel light. A lenticular lens (3) expands a beam of the first substantially parallel light converted by the collimator lens (2) into a linear shape in a first direction. A Fresnel lens (4) converts the beam expanded in the first direction by the lenticular lens (3) into second substantially parallel light. A free curved surface mirror (5) has a reflecting surface formed into a free curved surface, and expands a beam of the second substantially parallel light converted by the Fresnel lens (4) into a planar shape in a second direction orthogonal to the first direction. This arrangement enables to provide a planar illumination device with a small thickness and high light use efficiency.

The coaxial cable connector of the invention has: a contact to which a central conductor of a coaxial cable is to be connected; an insulation body in which the contact is place; and an outer conductor which has a tubular portion that is placed outside the insulation body with being separated by an annular space from the insulation body, and that has slits, an external conductor of the coaxial cable being to be connected to the outer conductor. A tip end face 4e of the insulation body protrudes more than the tip end of the tubular portion having the slits, in the insertion direction. The tip end face of the insulation body as viewed in the insertion direction exists in a minimum fitting range for the case where a cylindrical outer conductor of a receptacle is tried to be fitted into two adjacent slits of the tubular portion.

A plurality of contacts are assembled at prescribed spacings in a longitudinal direction of a receptacle body. Each contact has a meandering curved part in the intermediate portion for elastically contacting the corresponding contact. A ground member extending in a longitudinal direction of the receptacle body and passes through the inner area of the respective meandering curved parts of the contacts is combined with the receptacle body. The ground member is arranged at a position equally distant from the respective parts of the meandering curved part.

The invention provides a coaxial connector with a switch in which the life property and contact reliability of a movable contact piece portion are improved, which is further miniaturized and low-profiled than the conventional art, and in which the component configuration is simple, and hence the production cost is low. According to the coaxial connector 1 with a switch, in accordance with fitting with a counter connector, a plug pin 100 is elastically contacted with the plug pin contact portion 57 of a movable contact piece portion 51, and the movable contact piece portion 51 is displaced in a direction substantially perpendicular to the direction of insertion and extraction of the plug pin against the spring force, and separated from the stationary contact portion 41.
