Description

The invention relates to a projector for projecting one of a plurality of Biku-n at a time. all in the form of in one for all Bikic-r image parts arranged in the same predetermined pattern are located on an image carrier, with the same image parts of different images on the image carrier are combined to form a group of adjacent image parts, with a projection microlens field in front of the image carrier, with a microlens extending in front of each sub-image group, with one Lens, with a diaphragm opening in front of the movable perpendicular to the optical axis of the lens Projection microlens array, with one behind the Image carrier arranged symmetrically to the projection microlens field second identical illumination microlens field and with one behind the illumination microlens array symmetrical to the aperture displaceably arranged light source, according to patent I 808 258.

The images to be projected with the projector are generated according to the principle of multiple photography, for easier understanding of the invention below with reference to FIGS. 1 will be explained.

A motion picture projector is known for which a large number of individual images are placed on the image carrier concentric circles are arranged distributed. The individual images are cut out by means of a diaphragm system several discs rotating relative to one another in which mutually overlapping slots

are formed, depending on the position of the disks to one another from the overlapping part of the slots one after the other released for projection. For the best possible use of the available light the light beam with the help of rotatable prisms in the condenser system one after the other to the point of the straight to be projected individual image distracted. A pivoting mirror can also be used for the same purpose be provided, which deflects the emanating from a laterally offset light source Light beam controls.

With the main patent, a projector of the type mentioned is proposed in which the Individual images are arranged on the image carrier in a predetermined pattern and through a perpendicular Aperture opening that can be moved to the optical axis of the lens can optionally be called up, / ur uniform and effective illumination Tjil pictures are symmetrical in front of and behind the picture carrier a microlens field is arranged next to it, only the light source is optionally with the help of one swiveling mirrors arranged in a beam path, slidable symmetrically to the aperture by the symmetrical arrangement to the image carrier two microlens fields and the light source that can be moved symmetrically in the aperture

τ those parts of the image of the image carrier that are to be projected are illuminated, and the light source is used with minimal loss of light.

The object of the invention is to provide a projector

m to create the main patent in which the Moving from one image to another image requires basic motion sequences regardless of the hack of the operator run automatically.

This object is achieved according to the invention in that the aperture through the intersection 4clle two slots is released, each in one on two in normal planes to the optical axis of the Objectively perpendicular to each other slidably arranged plates transversely to the direction of displacement of the respective Plate run that for each diaphragm plate a common gear for incremental displacement the diaphragm plate and for the corresponding adjustment of the possibly apparent light source is provided, the two gears the light source with each displacement of the aperture at the same time bring into the corresponding symmetrical position, and that an image selection device is provided which, depending on the position of the selected image, the movements of the limited to both gears.

By pressing the image selection device, the adjustment of the projector parts for the projection of the runs selected image by means of the transmission automatically, after which the projector to select a new one Image on the image carrier is ready again.

The gears are preferably in both directions of rotation can be driven by means of a reversible motor, which is controlled by changeover switches are that for switching on the direction of rotation required for controlling the selected Hildes Transmission from a preselecting device of the image selection device can be switched on and as a function from the one corresponding to the selected position Transmission setting can be switched off. Since each motor has the assigned Diaphragm plate and the light source in the assigned direction of movement on the shortest path in brings the new position, only a short time elapses before the newly selected picture appears on the projection screen, the image selection device for switching on the correct direction of rotation each of the motors ensures.

This is achieved with advantage that a two-part switch for each of the motors Actuating device is provided with its actuating parts by means of one of the associated

ίο gear derived drive versus one of the Number of rows and columns of images on the image carrier corresponding number of operating levers the counting device is displaceable, the actuating levers being arranged in such a way that the

that actuation part, which with the for the Activation of the selected image required direction of rotation controlling switch z-.isammenektiven. from that assigned to the selected image position Actuating lever "is actuated and Tiit this through

the displacement of the actuating parts disengages as soon as the preselected Büdpositirri corresponding gear position is reached.

As a result of a misalignment of the operating levers, it does not gradually add up to a:

If there is an error when the respective motor is switched off in time, it is further proposed according to the invention, for each actuating device a holding device cooperating with its actuating parts to be provided, which is controlled by a control disk coupled to the gear unit assigned to the gear Depending on the position of the assigned gear for releasing the one in the switched-on position Actuating part is controlled. This means that the respective motor is switched off independently the exact arrangement of the B operating lever, so that every transmission is always stopped at exactly the right time when the aperture is opened has reached the selected image. The halfe device is advantageously adjustable.

According to the main patent, the slidably arranged light source can be one of a pivotable one A virtual image of a fixed real light source reflected in the light path. Through this the movement drive for the light source is facilitated. For an exact coverage of the assigned Microlenses on the two microlens fields also because of the pivoting of the mirror obliquely incident light beam is proposed according to the invention, the lighting

Microlens field for a movement by a small distance in two mutually perpendicular ones Directions normal to the optical axis of the lens by means of one driven by the gears To make adjusting device adjustable, the mirror by means of a coupled with the gears Drive simultaneously with the microlens field in the symmetrical position for the selected image position is pivotable.

The invention is explained in more detail below using an exemplary embodiment.

sharp on areas

Areas of the light or radiation sensitive material 4 corresponding to the exposed positions 3 and 3a of the aperture. Of course, the positions in which the diaphragm is shifted may be changed will not overlap with previous positions.

In this way, images can be recorded by moving the diaphragm 3 into new positions be until the entire area of the light or radiation sensitive material 4 with finely divided Partial images of the images formed by the lens 1 was exposed, these partial images do not overlap each other.

In the multiple photography described above, the number of to be photographed depends Scenes or objects of the ratio of when the light-shielding plate was removed to that described above Cover the exposed surface and the surface that can be exposed if the cover is present. The number of images recorded on a single piece of light or radiation sensitive material without whose displacement can be recorded is thus by the ratio of the effective area of the The lens is limited in the plane of the diaphragm to the opening area of the diaphragm.

For a calculation example, the following prerequisites should be assumed: effective diameter of the objective 1 at the aperture = 30 mm; Foot distance = 95 mm; Distance between the diaphragm and the image formed in the air by the lens 1 = 80 mm; Distance between the diaphragm and the lens 2 = 40 mm; aperture of the aperture = (1.2 mm) ² ; Division of the movement of the diaphragm in the horizontal and vertical direction = 3 mm. If the diaphragm can be moved in five steps horizontally and vertically, 5 * (= 25) objects can be photographed. A shutter can be arranged immediately in front of or behind the diaphragm or in any other convenient position. If the light or radiation sensitive material is firmly attached to the lens 2, the latter must of course be removed from the photographing device and developed in an appropriate manner.

From the above it can be seen that the images obtained with the multiple photography over the entire The area of the light- or radiation-sensitive material are distributed as finely divided partial images, so that it is impossible to directly determine what kind of pictures were actually taken. The developed partial images can be reproduced by the developed light or radiation sensitive Backward material in an optical system similar to that described above benen optical system is illuminated.

The invention relates to a device for projecting such finely divided partial images onto a device Screen, so that the original image of a lens is reproduced.

j The used stock the lens 2 described above is in Fenn a transparent plate with a plurality of en whose front surface attached Mikroiinsen and finely divided partial images of 25 Obiektivbildern. Therefore, a total of 25 push buttons are provided on the front panel of the device for selecting these objects or riders.

A helical gear wheel 181 is seated on the shaft 180 and meshes with a helical gear wheel 182, so that the rotary movement of the drive shaft 99 can be transmitted to a vertical shaft 183 arranged parallel to the vertical shaft 174. On the vertical shaft 183 sits a disk 185, on the top of which an eccentric pin 184 is attached. A control disk 186 sits at a distance on the shaft 183 under the disk 185. When the eccentric pin 176 rotates, a switch actuating assembly 187 // is rotated intermittently. When the vertical shaft 174 makes one revolution in the direction indicated by the arrow, the eccentric pin 176 is engaged with a recess 189a of a disc 188, so that the disc 188 is rotated in the direction indicated by the arrow. After a predetermined angle of rotation of the disk 188 i: l, the eccentric pin 17ό is out of engagement with the recess 189a. The angle of rotation of the disk 188 during one revolution of the eccentric pin 176 ao is the same as the angular distance between two adjacent and equally spaced recesses I89a, A89b etc. of the disk 188.

In a manner similar to that described above, the eccentric pin 184 causes intermittent rotation of a toothed disc 190 of another switch actuator 187 V htrviT. 39 shows a plan view of the eccentric pin 184 and the disc rotated thereby.

The switch actuating assembly 187 // is explained in more detail below with reference to FIGS. 30 to 36. Hine shaft 191. To the upper end of which the toothed disk 188 is attached. has a large diameter in its lower region 191a. A flange 191 6 is formed in one piece with the region 191a at the lower end of the shaft 191. Furthermore, in the area 191a with a large diameter and the flange 191 /) adjoining this, two axially extending grooves 192a and 192ft are provided diametrically opposite one another in order to accommodate tension springs 193a and 1936, respectively. Further, with "roßcm diameter a pair of wedges 194a and 194 b are secured to the portion 191a, which each at 90 ° to the grooves 192a l> 7w. 192 /> offset »are arranged. The shaft 191 is supported by means of a bearing 195 with a pair of fastening parts 1956 protruding on both sides of the bearing 195. The parts 195a are attached to a central plate 196 which is arranged at a small distance behind the front plate of the projector (FIGS. 3 and 4) and a support assembly 198 (Fig. 3). The switch actuator 187 // is attached to the front surface of the plate 196, and the vertical shaft 174 is supported by suitable bearings on the rear surface of the plate 196. The eccentric driven by the vertical shaft 174 Pin 176 (FIG. 8) is in operative engagement with the toothed disk 188 through a horizontally extending elongated opening 196a in the plate 196. That is, part of the circumference of the disk 188 protrudes inward through the opening 196a (see F. i g. 36 and 38).

When actuating the switch, VaI to VaS . The rotation of the motor 140 (FIG. 8) is, however, disadvantageous for the following reasons, so that the motors are reversed in this direction so that the switch actuation time is stopped. On the one hand, the parts 119a and 119b must be shifted from the positions of the arms Hai to HaS shown in FIG. 49 (a) and the upper positions to the left. Therefore, ends VaI to VaS with a higher accuracy, as can be seen from Fig. 49 (b), the degree of arm // ability can be determined. On the other hand, when disengaged from the switch operating part 119b , the timing at which the motors stop changes and the switch SHr is opened so that the motor 10 is stopped every time the button 140 is depressed from its reverse rotation so that the sliding plates for Bewird. Furthermore, the raised switch actuation mood of the position of a diaphragm is not stopped every time in the movement part 119aV from the same position shown in FIG. 49 (a). For example, location displaced to the left, while the switch SVf would, even if the positions of the arms Hai remains to be closed when the upper end Va3 except "5 HaS and the upper ends Kai to VaS with an engagement with the switch-actuating part 119aK overall desired degree of accuracy are arranged, which reached, the part is 119aV displaced downward so that the layers Schalterbetätigunßsaggregate 187 // and the switch SVf is opened, as seen in FIG. 187 V with respect to their eccentric pins under 4 · ^r '(b) is.

That's why hen creates. As a result, the drive shafts 107 and 99 are the invention devices to allow the switch actuator to maintain its working position in the directions indicated by the arrows 23 from the in F i g. 8 50 that the switch actuation tefl shifts positions into their limit positions immediately after the eezeieten.

If this is obvious, as shown in FIGS. 41 and 43 can be seen, connecting link 240 and the bent part 248σ are one ends of springs 246 and 247 which disengage from control disk 186, swivel arms 236 and 237 are attached while swivel arms 236 and 237 are attached to the other ends of these springs on the vertical springs 246 and 247 moved towards each other. Therefore shaft 174 are attached. 45 it can be seen, the hooks 241 swivel arm 236 endeavor to swivel counterclockwise and 242 on the flanges of the switch actuation clockwise direction, while the swivel parts 119aF and 119bV engage .

As can be seen from Fig. 43, corresponding hooks under the raised switch of the connecting member 240 are attached to the inner surface 55 by means of two screw actuating part, as can be seen from FIG the control is held in its raised position, as attacked from disk 186. The control disk 186 has Fig. 46 can be seen, it actuates the switch SVr, a control cam corresponding to the longitudinal section 60 so that the motor 142 (F 1 g. 8) is driven in reverse rotation by an egg, as best shown in Fig. 44 direction and is characterized is the scarf Gansterer Clearly Thus, the reverse rotation of the operation assembly at a 178 V ir "Rich rotation cam plate 186, the bent portion 248a is driven corresponds tung.

In fact, towards the rear, however, the hook 242 changes the switch actuating part from falling down, so that the switch remains closed and thereby the motor rotates while the control disk 186 does not continue to rotate. When the control disk 186 shifts the bent part 248λ to the right in B. of FIG. 41, the pivot arm ibel86 237 is pivoted about its bearing 235 in the counterclockwise direction, so that the lower end 237 α of the pivot arm 237 hooks 242 emotional,

In the following, reference is again made to FIG. 29 Reference taken through. When the upper end Va 3 is moved upwards g.24), the switch actuator 119α ^ disc is rotated in the direction indicated by the arrow. The switch operating unit with the

be actuated in an I mid-way until the upper end Va 3 ι should. I out of engagement with the lower end face of the switching operation parts ι l \ 9AV passes when the part of time runs 119aK over the upper end VaI. Thus, the eccentric pin 184 (Fig. 38) must revolve twice to drive the switch actuator. In the same way, when the upper end VaS moves the switch operating assembly 119aK upward, the eccentric pin 184 must revolve four times. When the eccentric pin 184 revolves several times, the control disk 186, which is seated on the same shaft, performs the same number of revolutions, so that the pivot arms 236 and 237 are moved to and fro. Therefore, the hook 242 (Fig. 46) is pivoted by the lower end of the switch actuator so that the hook 242 is moved under and away from the lower end of the switch actuator. The switch actuation member U9bV is, even when the hook 242 wegbewe from its lower end face? T (Fig. 46) held by one of the upper ends of VaI to VaS in its raised position so that the TEU rotates 119 bV while on the upper end holding it in its raised position slides away. After the lower end face of the part wn the upper end has been released, the switch actuating part 119 bV can finally move downwards after the pivoting movement of the hook 242. The pivoting movement of the hook 242 is triggered by the cam disk 186, which pushes the bent part 286a to the left in the figure

The device for maintaining the working position for the switch actuation unit has been described for the unit 187 V. The device for maintaining the working position for the unit 187 Λ has the same construction and operation as the device described above, so that its description is not required

The device described above for maintaining the working position allows the time of the <\ nhold the by pressing a picture selection pushbutton The motor that has started can be determined more precisely with the aid of the control disk driven by the motor. This will give the benefit achieved that the two horizontally and vertically movable plates 22 and 23, which dutch the motor are driven, in exactly those determined by the selected and depressed push buttons Layers can be stopped.

The lighting system used in the projector according to the invention will now be described. The system generally has a lamp 25 as a light source, the movable mirror 20, the

is condenser lens 19 and the micro-iron plate 18. A plurality of images A ', B', C, D ' etc. are recorded on the original (a positive or a negative) by means of multiple photography, which is shown schematically in FIG. 20 is shown. The invention is as follows

ao described under consideration of the case that an arbitrarily chosen picture, e.g. the picture / T. is selected by an image selection push button and displayed on the screen 6 (Figs. 2 and 6) will. If the original 17 is a number of N

»5 that has, an image takes up i / N the area of the original. For a better representation of the partial images recorded on the original, adjacent images are arranged at a distance from one another. When the ratio of the area with image recording ti

to the total area of the original is η (η <. \) , the area for recording the partial images of an image becomes (VN · η). It can therefore be seen that when the original is illuminated evenly over its entire surface by the light surface, as in the case of a conventional slide projection system, only η.'Ν of the illuminating light is used to illuminate the image A ' . As described above, in the present embodiment, N = 2f and η = 0.6. The actual intensity of the illumination light in the projector according to the invention must be W />) (= 41) times the intensity of the illumination light required for a conventional slide projector.

The projection system in the case of multiple photographers is similar to that used in photography, so that the projection light could most effectively be used when it is in the opposite direction along the optical path; light used in photography would run. For this purpose, in the present embodiment, the in FIG. 17 optical systems shown used for the projection. The lamp 25 and the diaphragm Ap are symmetrical to one another in relation to the center C of the emulsion surface of the original 1 "

arranged. The position of the aperture Ap is changed as a function of the selected image, so dai

. the lamp 25 depending on the Verlagenuij

the diaphragm must be shifted accordingly so that it is symmetrical with respect to the diaphragm is ordered as described above Because of the mechanism required for this, e is: however, very difficult to move the lamp 25 depending on the displacement of the diaphragm horizontally and ver relocate tically. Therefore, in the present "

Embodiment of the projection device according to the invention, instead of the lamp 25, the movable deflecting mirror 20 is displaced in accordance with the displacement of the diaphragm Ap . As explained above

becomes, the movable mirror 2G becomes around both vertical and horizontal axes pivoted. Thus, when the movable plate 22 (Fig. 8) is in the position indicated by the arrow Direction is shifted, the protruding from the movable mirror 20 pin through the cutting 115 a the displaceable plate 115 displaced so that the mirror 20 is pivoted about the vertical axis. On the other hand, when the vertically displaceable plate 23 moves upward, the pin 114 will move shifted upward so that the movable mirror 20 is pivoted about the horizontal axis.

When the movable mirror 20 is pivoted around both the horizontal and the vertical axis depending on the displacement of the diaphragm in the horizontal and vertical directions in accordance with the depression of a pushbutton to select an image to be projected, the displacement of the light source can be approximated with this. In this case, as can be seen from FIG. 18, the virtual image 25 A of the lamp 25 is displaced on a spherical shell. However, if the distance between the plane mirror and the light source is sufficiently large, the induced by the displacement of the virtual image 25 A on a spherical shell error can be neglected.

In order to use the light source more efficiently, the thickness of the micro lens 18 is made smaller than those of the original shown in Fig. 17, and the light rays of the projection or illumination light converge after passing through the original 17, so that the loss of the projection light is theoretically eliminated. In practice, however, it occurs a loss due to diffusion through the emulsion surface as with conventional slide projection on, so that the projector according to the invention with respect to the area of an image to be projected, the Brightness, the projection light source, the brightness of the screen when projecting, etc. with one conventional color slide projector can be compared. Therefore, in the projector according to the invention a convenient conventional projection light sourcec can be used and the heat of the light source can be used in any known manner, e.g. B. by using a fan 125 located at the rear of the projector to cool the Lamp section, are discharged.

Dm to arrange the diaphragm and the light source symmetrically with respect to the center Γ of the emulsion surface of the original for an effective use of the projection light, the microlens plate 18 must be displaced together with the light source depending on the displacement of the diaphragm or the selection of an image to be projected will. The mechanism for displacing the microlens plate 18 depending on the selection of an image to be projected has already been described. 8, when the horizontally movable plate 22 is displaced in the direction indicated by the arrow by the shaft 107 , the stopper 14 is displaced in the direction indicated by the arrow, so that the square frame 83 holding the microlens plate 18 is moved. When the vertically movable plate 23 is moved by the drive shaft ¹ M, the stop 3 is moved downwards, so that the square frame 83 is also moved downwards.

Subsequently, aiii I · 'i g. S Ikvug taken. To transfer the rotary movement of the drive shaft 107 into a linear movement of the stop 94, a worm 108 seated on the drive shaft 107 meshes with a worm wheel 103, which in turn meshes with a further worm wheel 105. The worm wheels 103 and 105 each sit on threaded spindles 102 and 104, which have threads with opposite screwing directions. When the movable plate 22 to choose from

to move the aperture one step further, must the microlens plate 18 can be moved by about 0.2 mm. By arranging the above described Worm, worm gears and lead screws can provide accurate movement of the

Microlens plate 18 can be made with a higher degree of accuracy in a simple manner.

The tolerances become very tight. if only a single image is desired for projection should be illuminated. Therefore, in the present embodiment, is the area to be illuminated slightly enlarged, as a result of which inaccuracies may still occur in the present method be eliminated. According to one method, the light source is closely aligned with microlenses.

orderly. With this method, however, the rays of light disappear after they have passed through the images depends on the desired optical path, so this method is not preferable. Another method is to keep the light source relatively large compared to the aperture. With this method, the disadvantages or errors described above are minimized and in practice it is very easy to use a lamp with a light radiation area or

to provide a light-emitting area which is larger than the area of the diaphragm of about 1 to 4 mm ' ² .

The following is a brief overall description of the projector and its mode of operation will.

(1) The projector is used to project »originals«, which are made by means of a multiple photographic device with a first lens of a movable diaphragm 3 and a second lens with a A large number of microlenses were produced. The original can be one piece together with the second lens form and be removably held in the projector. The projection lens of the projector corresponds optically the first lens, and at the

The rear of the projection lens is an aperture through the crossover of a pair in the elongated slots of a pair of horizontally and at right angles to one another vertically movable plates formed. The panels are shifted horizontally and vertically in steps, to choose a diaphragm in a certain position through which a selected image is projected can be. In the embodiment described above, the bottom plate has 154

just as many possibilities for the position of the door opening. how images are recorded on the original being used. Any of these aperture positions can be selected to be projected through the pair of movable screen panels. But when moves the pair of these movable plates to a desired position with a higher degree of accuracy and stopped there, the shutter plate 154 can be omitted. In this case it can

the image is more movable directly through the crossover of the elongated slits of the pair Plates formed movable diaphragm are selected.

The position of the relocated aperture can be determined by the arranged on the front of the projector Image selection unit can be selected. The movable plates to form a relocated Aperture openings can be driven by a drive mechanism which is controlled by signals is controlled, which are transmitted from the image selection unit. The drive mechanism is arranged between this unit and the pair of movable plates.

A lighting system is arranged at the back of the original, and the finely divided partial images on the original can be projected under magnification onto a screen which does not necessarily have to be provided on the housing of the projector. When the projection screen M ¹ H is a sufficient distance from the projection lens. For example, an image can be projected on the screen at a larger magnification scale. It is desirable that focusing can be carried out from outside the projector.

If you want to copy the projected image, s will get a mirror image if -.- in with a silver halide sensitized copy paper is placed on the screen. Therefore this has to be done Projection housing 21 with the deflecting mirror 14 can be removed from the projector. The copy paper can then be arranged directly in front of the projection lens. The copying process is made easier when a copy paper holding device attached to the rear of the projector and the projection lens optically with the copy paper through a frustoconical light shield / ylinder connected is. The lock can inside the lens barrel, -or the lens or at any other convenient location for exposure.

(2) The pair of movable plates described above is driven by independent drive shafts. The drive shafts are in Driven by motors in both directions of rotation.

The motor circuits have changeover switches for reversing the direction of rotation of the motors. The changeover switches are operated in response to the image selection process, so that the movable ones Plates by the motors in a predetermined position to form an aperture at a predetermined Position can be moved.

Around the displaceable diaphragm opening or diaphragm at a predetermined position with a higher To form a degree of accuracy, means are provided to keep the changeover switches closed. In the present embodiment, the hooks are used to hold the switch operating parts to hold in their operating positions in the switch actuation units. The facilities are however not limited to such hooks.

The switch, which is closed by the device for maintaining the operation of the switch is opened by the switch actuating part coupled to the drive shaft, when the aperture or aperture has been formed in the selected position.

The accuracy in the operation of the projector is achieved by the fact that a pair of movable plates is provided to form a movable screen. that drive shafts are provided, each of which one for driving each of a plate independently of the other are provided that Motors for the drive shafts are provided that in the motor circuit switches for reversing the direction of rotation of the motors are provided that devices are provided to close the switch to hold and that means for opening the switch at a predetermined time are provided.

(3) The device for maintaining a switching position is provided with a ^ attack part, which is moved by the yoke carried by the shaft. The shaft, in turn, is driven by the drive shaft turned. The control disk is used to move an attack part to the switch open when the movable shutter is in a predetermined position. Through functional Setting the position of the cam in relation to the attack part can be the point in time at which the switch is opened. d. H. point of time. 71! which the motors are stopped and the movable shutter in a predetermined position is to be set.

The accuracy of operation of the projector will be further improved in that the attack part described above is designed to be adjustable. When the blender plate left, and the images to be projected are selected directly through the movable shutter the function of the attack strength is very important.
