Abstract
The utility model relates to an improved projector. The utility model is formed by that on the basis of the whole structure comprising a lamp box, a focusing rod, a lens and a reflecting mirror, the utility model is additionally provided with an objective table arranged on a focusing mechanism, and an assisting light source which irradiates the objective table. The lens and the reflecting mirror are supported in front of the objective table, and thus the projector can transmit and project patterns on a transparent carrier, and can reflect and project images or real objects on an opaque carrier arranged on the objective table. The utility model obtains the effects of flexibility, multiple functions and vivid image.
Description
The utility model belongs to the porjector technology field in the optical device.Existing teaching is transmission-type with projector.Mainly by lamp box, slide glass glass, convex lens, parts such as catoptron constitute.The pattern amplification that its function just will be plotted on transparent film or the clear glass projects in the screen.But the pattern of this projector on can only the projection transparent carrier then can't projection to pattern on the nontransparent carrier or material object.To these phenomenons, Projection Display if desired, graphing on transparent carrier again, this has not only increased workload, and the people of artistic grounding in basic skills deficiency is also had suitable difficulty.
The purpose of this utility model is to transform at existing projector, makes it that the image on the nontransparent carrier or material object are projected to screen and gets on.
The technical solution of the utility model is the lamp box that keeps existing transmission-type projector, the focusing lever, camera lens, catoptron, the focusing that are installed on the lamp box are turned round on the basis, between lamp box and camera lens, increase an objective table and secondary light source, make light imaging after the picture on the objective table, photo or reflection in kind, projection.Objective table is wherein made of metal base plate and heat-protecting glass, is installed on the focusing lever.
Using good effect of the present utility model is pattern on not only can the transmission projection transparent carrier, and can the nontransparent carrier of reflective projection, as the image on photo, the picture and even in kind.Not only enlarged accommodation, and the image fidelity of reflection.Also removed a large amount of work of drawing again on transparent carrier from.Make projector further adapt to the school and the cultural place of the relatively poor remote districts of a lot of conditions.Promote teaching there and the development of cultural activity.
Accompanying drawing is a synoptic diagram of the present utility model,
Embodiment of the present utility model comprises following content: adopt the lamp box 1 of existing projector, focusing lever 2, camera lens 6, catoptron 7.Objective table 4 is installed on focusing lever, and the size of objective table is decided with the size of picture commonly used, material object.Objective table base plate metal material is equipped with heat-protecting glass and covers photo on it.The box-like of band edge frame around the picture holding piece being arranged on the objective table or making on the base plate.In order to make full use of light, the internal direction of frame is made concave surface.Objective table moves along focusing lever so that the focusing twisted strip is moving, to finish focusing.Secondary light source 3 is being installed on the focusing lever or on the lamp box shell, is being shone light intensity on the picture, guaranteeing the readability of projection with increase.Secondary light source is made up of bulb, concave mirror, convex lens, heat-protecting glass.Camera lens 6 and pole 5 of catoptron 7 usefulness are installed in the dead ahead of objective table.Below promptly finish basic structure of the present utility model.Use-pattern of the present utility model is if the pattern on the projection transparent carrier is identical with existing mode.If the pattern on the nontransparent carrier of projection, the lamp box that then need fall is opened secondary light source, and picture is pressed under the objective table heat-protecting glass, adjusts the position of camera lens and catoptron, and moving stage can obtain clear image true to nature in screen.
