Abstract
A bi-directional projector capable of projecting in two different directions. The technical scheme is as follows: the semi-reflecting mirror is additionally arranged between a condensing prism of the projector and a light path of a main lens of the projector, so that a part of light passes through the semi-reflecting mirror to keep the original direction, is projected through the main projection lens, and the other part of light is reflected by the semi-reflecting mirror to be projected through the 90-degree auxiliary projection lens in the 90-degree direction, and the projection in two directions perpendicular to each other can be realized. If a reflector is additionally arranged on the light path in the 90-degree direction, the light path is refracted by 90 degrees again, and the bidirectional projection in the 180-degree direction can be realized. The control button controls the position of the half-reflecting mirror to leave or enter the light path, so that the switching of unidirectional or bidirectional projection can be realized. In the state of bidirectional projection, the reflector is controlled to leave or enter the light path through the control button, and the switching of 90-degree bidirectional projection or 180-degree bidirectional projection can be realized.
Description
Technical field
The present invention relates to a kind of projecting apparatus, the projecting apparatus that can be especially projected to two different directions simultaneously.
Background technology
Projecting apparatus is widely used in the occasions such as commercial affairs, office, teaching and amusement.At present, known projecting apparatus is all single mirror
Head one direction projection.When used for the meeting room sat around desk and large-scale meeting-place, the back of the body can be made in order to solve one direction projection
The too big problem not seen at a distance in and meeting-place inconvenient to the beholder of projection screen, conventional method is many projections of arrangement
Instrument.But for general meeting room and the maximum school's lyceum of projecting apparatus usage amount, arrange many sides of projecting apparatus
Case feasibility is poor.
The content of the invention
In order to solve the above problems, the present invention proposes that a kind of novel projector can be realized being carried out in two different directions
Projection.
The technical solution adopted for the present invention to solve the technical problems is：There are principal view camera lens and auxiliary projection lens on projecting apparatus
Head, main lens are equal to the camera lens of existing projecting apparatus, and auxiliary projection lens is with main lens in 90 ° or 180 ° arrangements.In projecting apparatus
Increase a half-reflecting mirror of 45 ° of arrangements in the middle of the light-collecting prism in portion and the light path of principal view camera lens so that the light one of imaging
Partially pass through half-reflecting mirror to be projected away according to original direction by principal view camera lens, the light of another part imaging is anti-by half
Mirror reflection is penetrated to be gone out by the auxiliary projection lens projects of 90 ° of arrangements, or the light of another part imaging passes through 45 ° of cloth again
The speculum put is gone out by the auxiliary projection lens projects of 180 ° of arrangements.Increase half-reflecting mirror control in the control circuit of projecting apparatus
Button processed, controls the position of half-reflecting mirror, if half-reflecting mirror leaves light path, all imaging light is not reflected directly from master
Projection lens is launched, and is equal to original single-lens projecting apparatus；If entering half-reflecting mirror by half-reflecting mirror control button
Light path, then be capable of achieving two-way projection.Increase speculum control button in the control circuit of projecting apparatus, control speculum leaves light
Road, it is possible to achieve 90 ° of two-way projections, control speculum enters light path, is capable of achieving 180 ° of two-way projections.
The beneficial effects of the invention are as follows using an original light source of projecting apparatus, a set of three colors image-forming assembly and poly-
Light prism, only increases removable or rotation half-reflecting mirror, removable or rotation speculum and auxiliary projection lens, it is possible to
Realize two-way projection.By the operation of control button, original unidirectional projection function can be maintained, it is necessary to when can switch
In 90 ° or 180 ° of two-way projections.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
