A lighting device that is capable of illuminating in all directions includes: a case that includes a plurality of wall portions each including a face in a polygonal shape; a plurality of light-emitting elements that are provided in the plurality of wall portions and emit light toward outside of the lighting device; and a controller that controls the plurality of light-emitting elements separately. The case is of an outer shape that is spherical or polyhedral. The case includes bent portions that are bent in the outer shape of the case. The bent portions constitute at least three sides of the outer shape of the case.

A connector holding mechanism includes a biasing member provided in a through hole formed in a bottom plate of a storage body, a cover having a connector insertion hole and an inclined surface which is fixed to the through hole, a connector, in which a terminal is loosely inserted into the connector insertion hole, and a flange portion protruding from an outer periphery of the housing biased by the biasing member. When the connector is waiting to be fitted to a stored object, the connector is held in a posture where the terminal is inclined due to abutment between the inclined surface and the flange with respect to a virtual line perpendicular to the bottom surface, and when the connector is fitted to the stored object, the connector is held in a posture where the terminal is vertical along the virtual line.

Connector holding mechanism

A tonearm unit includes: an arm member having a tip to which a cartridge is attached; and a raising and lowering mechanism which raises and lowers the arm member with respect to a phonograph record along an axis. The raising and lowering mechanism includes: a cam base supporting the arm member; a ring cam provided to be rotatable about the axis with respect to the cam base; a first guide portion on the cam base, extending at an angle along a rotation direction of the ring cam; and a second guide portion on the ring cam, extending at an angle along the rotation direction so as to face the first guide portion. When the ring cam rotates with respect to the cam base, the cam base is raised and lowered with respect to the ring cam as a result of the second guide portion sliding along the first guide portion.
