Abstract: A projection system includes a screen, an image projection device configured to project an image on the screen, and a carrying platform on which the image projection device is mounted, and which is configured to move, wherein the carrying platform includes a projection direction variable part which is configured to change a projection direction of the image, and a support mechanism configured to support the screen so as to adjust a position of the screen in a direction crossing an installation surface on which the carrying platform is installed.

Abstract: A projector that modulates and projects light emitted from a light source includes an exterior housing configuring the exterior of the projector, a cooling target separably attached from the outside of the exterior housing, a cooling fan configured to deliver a cooling gas to the cooling target, and a channel forming member forming a part of a channel in which the cooling gas delivered from the cooling fan flows. In a state in which the cooling target is attached to the projector, the cooling target and the channel forming member form the channel. The cooling gas flows in the channel along the cooling target.

Abstract: In a push-button switch device for a vehicle including a first case member fixed to a vehicle body or a lid openably and closably mounted on the vehicle body, a second case member mounted on the first case member forming a case together with the first case member, a push-button supported on the case configured for a pushing operation, and a switch housed in and fixed to the case in a state in which waterproofness is ensured while a switching mode thereof is changed in response to a pushing operation of the push-button, the entrance of water into the case is suppressed as far as possible. A labyrinth passage bent up and down is formed between the first and second case members further inside than an abutment part formed by mutual abutment of at least upper edges among peripheral edges of the first and second case members.
