Liquid injection device for medical use

A projector includes a projection optical device and a projection position adjusting device that includes a fixed member defining a hole having a step portion, a first plate that supports the projection optical device and a second plate disposed between the fixed member and the first plate. The projection position adjusting device further includes a connecting member having a step and being disposed in the hole of the fixed member and connected to the first plate, and an urging member disposed between the connecting member and the step portion of the hole of the fixed member. The urging member urges the step portion of the hole and the step of the connecting member away from each other, and urges the first plate into direct contact with the fixed member.

A projector includes a light source device, a optical modulator which modulates luminous flux emitted from the light source device according to image information, a projection optical device which enlarges and projects the luminous flux modulated in the optical modulator, and an outer casing which houses the light source device, the optical modulator and the projection optical device thereinside, in which the outer casing has a ceiling surface and a bottom surface intersecting with respect to the vertical direction and a side surface connecting to the ceiling surface and the bottom surface, in which a concave portion which is recessed toward the inside is formed at the bottom surface side in the side surface, and in which a first connection terminal group connected to an external device through connection cables is arranged at a bottom portion of the concave portion in an exposed state.

Projector

The invention has an object of providing a display device, which can freely change a display position or a display area, and can display a high grade image, and a game machine, such as a slot machine etc., which includes the display device.

Display device and game machine

A projector includes: a projection position adjusting device that adjusts a projection position of a projection optical device. The projection position adjusting device includes: adjusting and driving units that move a first moving plate and a second moving plate. The adjusting and driving unit include: a pair of worms that have a columnar shape and have threads on outer circumferences thereof; and a pair of sliders that are screwed in the pair of worms, respectively. The pair of worms are disposed to extend along the first direction or the second direction. One of the sliders engages with one of moving plates. Engaging structures including inclining engaging holes that extend in a direction crossing the direction in the plane orthogonal to the projecting direction and engaging projections inserted through the inclining engaging holes are provided in the other slider and the other moving plate.

An illumination device includes a light source that emits light-source light, a light recovery member that is disposed close to the light source in the vicinity of a lateral side of the light source, and has a light receiving surface inclined at a predetermined angle with respect to an optical axis extending from the light source to the front to face the optical axis or the vicinity of the optical axis, and a rod integrator that uniformizes light-source light from the light source and light-source light reflected by the light recovery member.

Illumination device and projector

An illuminator includes a polarization converter that converts source light into first polarized light, a polarization separation member that separates the first polarized light of from the polarization converter and second polarized light different from the first polarized light, by reflection and transmission, a polarization switch member that reflects the first polarized light passed through the polarization separation member and changes same into the second polarized light, and a light guide having a first rod arranged between the polarization converter and the polarization separation member, a second rod arranged between the polarization separation member and the polarization switch member, and a third rod arranged on an optical path of the second polarized light separated by the polarization separation member.
