Provided is a light source device including a laser light source group including at least one multi-emitter laser light source and at least one non-multi-emitter laser light source that emits a colored light different from that of the multi-emitter laser light source, a collimator lens having at least one cylindrical surface that adjusts a laser light emitted from the at least one multi-emitter laser light source, and a light guide unit that performs color synthesis of a laser light emitted from the at least one multi-emitter laser light source and having passed through the cylindrical surface and a laser light emitted from the at least one non-multi-emitter laser light source.

Light source device and projection type display device

Provides a hitch carrier that is highly versatile for a bicycle that is loadable and that ensures stable loading of a bicycle. A hitch carrier for loading a bicycle including a frame that includes a top tube, a down tube, and a sheet tube, includes a first arm engaged with a first cradle including a supporting portion that supports the top tube, a second arm engaged with a second cradle including a supporting portion that supports the down tube, and a post supporting in a cantilever manner both the first arm and the second arm separated in a vertical direction. Fastening belts are disposed on the first cradle and the second cradle to fasten the top tube and the down tube, respectively.

Hitch carrier

A bicycle-fork support device configured to hold: a conventional fork, allowing insertion of a quick-release-skewer support shaft, in a lower end portion of the fork of a bicycle; a through-axle fork where a through-axle insertion hole for securing a through-axle hub formed in a lower end portion of the through-axle fork, and configured to deal with outer diameters of through-axle forks. The support-fork switching unit includes: a support-device main body where a hollow portion is formed; end portions formed in right and left end portions of the hollow portion; a conventional-fork-use supporting body including, a contacting portion formed with an internal shape that fits the support shaft; a through-axle-fork-use supporting body including, a contacting portion formed with an internal shape that fits the through axle; and a unit for removably mounting any of the supporting bodies on the right and left end portions.
