摘要： In a cover (1) for overhead transparencies (not shown) and consisting of a pocket (2) with ring file holes (9) and a non-transparent mask flap (3) to cover the part of the light plate of the projector which is not covered by the pocket (2), the novelty is that the mask flap (3) is hinged to the pocket (2) at the edge which is opposite the edge with the ring file holes (9). This provides a plurality of advantages, e.g.
- that the cover is easy to manufacture and therefore inexpensive, and
- that the opposite side of the mask flap may be used as an index leaf for the cover when it is placed by means of the holes (9) in a ring file (not shown) together with several other covers of the same type.

摘要： In a projection device according to the present invention, light from a point light source unit (30) is reflected by a first reflecting mirror (21) to produce parallel rays, which are applied to a color active matrix liquid crystal display unit (22). The parallel rays having passed through the liquid crystal display unit (22) are converted by a second reflecting mirror (23) into a bundle of rays of a desired solid angle for projection onto a screen (13).
摘要翻译：在根据本发明的投影装置中，来自点光源单元（30）的光被第一反射镜（21）反射以产生施加到彩色有源矩阵液晶显示单元（22）的平行光线，。已经通过液晶显示单元（22）的平行光线被第二反射镜（23）转换成所需立体角的光束，以投影到屏幕（13）上。

摘要： A transmissive overhead projector (10) includes a Fresnel lens assembly (26) which has an f-number of about 0.25 and is capable of dioptrically focusing light at an incident angle of at least 60° with respect to a perpendicular to the Fresnel lens assembly (26). This refractive power of the Fresnel lens assembly (26) allows the overhead projector light source (22) to be positioned very close to the Fresnel lens assembly (26) and consequently allows a significant reduction in the base height of the overhead projector (10).

摘要： Device for display and possible collection of sheet-shaped information carriers The device comprises firstly a bottom plate (10) prodded with a display aperture (20) intended to be positioned on e.g. the picturepane of an overhead projector, and secondly on two opposite sides of the display aperture (20) two ring mechanisms (20, 24) for retaining the informatin carriers, which preferably have double perforations along two opposite edges. Preferably, the ring mechanisms (22, 24) are coupled together with a transfer device (34, 38, 40) adapted to be actuated by means of an operating handle (48) for alternately opening and closing the two ring mechanism (22, 24). If desired, the bottom part (10) is provided in conventional manner with back parts (16, 18) and binder covers (12, 14) in order at the same time to constitute a collection binder for the inserted sheet-shaped information carriers.

摘要： A light source (L) is provided on an optical axis (O-O), and first and second reflectors (M1), (M2) are set firmly in the vicinity of the same optical axis. These reflectors consist, for example, of curved surfaces extending around the optical axis (O-O). The first reflector (M1) has such a three-dimensional shape that it can reflect a beam from the light source (L) so that the distribution of the beam becomes uniform. The second reflector (M2) has such a three-dimensional shape that it can receive and reflect the beam reflected on the first reflector (M1), to focus the resultant beam at a point (13) on the optical axis (O-O). Owing to such an arrangement, the beam leaves one point (13) and has a predetermined directivity. Accordingly, if an original (11) is placed in the path of the beam, a correctly-focused image of the original (11) is formed on a screen (S) no matter what the distance from the original (11) to the beam-focused point (13).

摘要： A light source (L) is provided on an optical axis (0-0), and first and second reflectors (M 1 ). (M 2 ) are set firmly in the vicinity of the same optical axis. These reflectors consist, for example, of curved surfaces extending around the optical axis (0-0). The first reflector (M,) has such a three-dimensional shape that it can reflect a beam from the light source (L) so that the distribution of the beam becomes uniform. The second reflector (M2) has such a three-dimensional shape that it can receive and reflect the beam reflected on the first reflector (M,), to focus the resultant beam at a point (13) on the optical axis (O-O). Owing to such an arrangement, the beam leaves one point (13) and has a predetermined directivity. Accordingly, if an original (11) is placed in the path of the beam, a correctly-focused image of the original (11) is formed on a screen (S) no matter what the distance from the original (11) to the beam-focused point (13).
