PROJECTION IMAGE DISPLAY APPARATUS

摘要

A projection image display apparatus which performs an operation for attaching and detaching a projection lens by one action with a simple mechanism is provided. The projection image display apparatus includes an optical engine which irradiates a display element with light emitted from a light source to form an image, a projection lens which enlarges and projects the image emitted from the optical engine, a lens shift mechanism for adjusting a position of an image to be projected onto a screen, a lens attachment unit for attaching the projection lens to the lens shift mechanism, and a first plate for attaching the projection lens to the lens attachment unit to achieve a locked state, and the attachment of the projection lens to the lens attachment unit and the achievement of the locked state are performed by only rotation of the first plate in a first direction. Also, detachment of the projection lens and release of the locked state are performed by only rotation of the first plate in a second direction opposite to the first direction.
