Claims

[Scope of Claim for Utility Model Registration] (1) In an overhead type dual-purpose liquid crystal projector having a cooling means for cooling the liquid crystal with cooling air, a liquid crystal display member is attached to the document surface on the main body so as to be openable and closable. An overhead device characterized in that it can be freely switched between displaying a liquid crystal display by overlapping a liquid crystal display member on the document surface and projecting an original on the document surface by separating the liquid crystal member from the display surface. Multi-purpose LCD projector. (2) The above-mentioned liquid crystal cooling means is provided in the main body, and the cooling air from the liquid crystal cooling means in the main body is guided to the liquid crystal cooling system path under the condition that the liquid crystal display member is stacked on the material surface and set at the projection position. An overhead type dual-purpose liquid crystal projector according to claim 1 of the utility model registration claim, characterized in that: (3) When the liquid crystal display member is set at the projection position, connectors for power, signals, etc. necessary for controlling the liquid crystal part are automatically connected. The overhead type dual-purpose liquid crystal projector according to item 1. (4) Claim 1 of the utility model registration claim, characterized in that when the liquid crystal display member is set at the projection position, switches for power, signals, etc. necessary for controlling the liquid crystal are automatically turned on. The above-mentioned overhead type liquid crystal projector.
