Copy device ■.

The invention relates to a copier, namely in particular to a photographic copier with a cover device for a document to be copied and a masking device to change the lighting opening depending on the set frame size ".

There are already various photographic copying machines known to be used for documents of different sizes. in the Such a device is described in U.S. Patent 2,213,734 which a cover device a document in a photographing field holds, and wherein, a masking device with an exposure aperture is provided to set the exposure on one, specific To restrict part of a photosensitive material, which is arranged in an exposure plane. The exposure device has a movable cover rail for changing the size of the surface on which

a document is to be included. In this way, the Cover device to accommodate documents of different sizes. The masking device has to change the exposure aperture size a movable masking disk, so that the exposure of different sized parts of the photosensitive material is made possible. The cover rail and the masking disc are ' connected within the photographic copier in such a way that the manual movement of the cover rail a proportional or similar movement of the masking disk result Has. In this way, the aperture size on the masking device can be changed in relation to the area size, taken up by a document lying on the cover device will. ■

Because the cover rail in the photographic one just described Copier is hinged to the masking disk, the cover device can not be removed from such a device. For this reason, under darkroom conditions it can be difficult to get into the covering device differently to bring in large documents and to arrange the cover rail exactly (each time after inserting a document of different sizes) to determine the size of the sealing opening in. right way to change. ,. ■■ - '..,

Another example of a photographic copier for different sized documents is described in US Pat. No. 3,488,119, where a plurality of document holders are provided to accommodate a different sized document at a time. That means that each document holder can only hold a certain size of a document. These document holders. can in _; . = the photographic copier are exchanged, and each have a physical display of the specific document size contained. As a result of the movement of a document part holder into the photographic copier device, a control device in the device first senses the physical display on the document holder and then changes the size of the exposure opening of a masking device by moving a masking device.

disc"

While US patent, 3,488,119 compared to US * patent 2 213 734 provides a document holder that can be removed from the photographic copier, a large supply must be kept of document holders for different sizes. Documents be entertained

There is therefore a need for a photographic printing apparatus in which the size of an exposure opening on a masking device in relation with the size of that surface can be changed, which is occupied by a document on a document holder., Wherein the document-holder is formed such that it can optionally accommodate different sized documents' and can be moved into and out of the photographic copier.

The present invention therefore aims very generally at one specify photographic copier which avoids the above-mentioned disadvantages and in particular a fast, far, automatic and reliable copying permitted.

Accordingly, the present invention provides a photographic copy machine device before which one to change the framing surface adjustable cover device, one to change the opening adjustable masking device, one · the inward movement and. the outward movement of the covering device into the photographic one Copy device permitting access path and züsammenar-. has additional members which are arranged ah the Abdeekvorrichtung and the masking device and then cooperate when the cover device is moved into the photographic copier device to determine the size of the opening in relation to the Size of the area. To change.

According to a preferred embodiment of the present invention is the covering device for receiving a document formed on the surface framed by the cover rails and can accommodate documents of different sizes because the

4Ö9 ^! 819/08 6 3 Y

Size of this area can be varied. Thereby are in the
Photographic copier means are provided for holding the covering device after it has been inserted into the device
into .and into-the photographic field of the device is moved. Furthermore, as will be described below, the masking device is supported within the photographic field to mask generally around the area framed by the cover rails so as to regulate the amount of light passing through this area for the purpose of image projection. Alternatively, as suggested in the prior art, the masking device can be held in the photographic field in such a way that the exposure is only on a selected one
Part of the photosensitive material is restricted, which in, an exposure plane of the. photographic copier is arranged.

Further preferred embodiments of the invention result
especially from the subclaims. Some of the sub-claims are discussed below.

As already mentioned, a photographic copier with a document holder for holding it can be of various sizes
Documents to be equipped; this document holder can have a cover device. In general, at least one of the cover rails is for the purpose of changing the size of the
Movable surface for holding documents of different sizes. The cover rails can be used for masking around a document
around or just to define the
Document on the document holder. Before the document holder is now moved into a document copying position within the copying device, the cover rails must be locked manually in a selected relative position so that they do not move. After the document has been copied, the document holder is then removed from the copier again and the cover rails are manually unlocked, so that the document
can be removed from the document holder. At a

409819/0863

Such a way of working is of course consumed a lot of time because the user lock the cover rails by hand and must unlock «-.

The present invention therefore aims to provide a holding frame locking device which works automatically, that is to say automatically. '~ ^; "- ■■ '·'

To this. The purpose of the invention is to provide a photographic, copier device a support frame locking device,

at least ■ · ■ · -. : which 1) / one of several holding frame rails on a movement as a result of the movement from the document loading and removal position out, and wherein 2) at least one of the Holding rails. Is released for movement, namely at moving into the document loading and unloading position.

According to the invention, the document holder is on the copier for a movement between a document copier position and a document loading and unloading position. A cover device attached to the document holder has a variety of cover rails that are used to frame the serve the area occupied by the document. In particular, the holding frame locking device has a holding piece which between a locked position and an unlocked position The covering device also has movement devices. to. the retaining piece between the locking position and the unlocked position as a result; the movement of the Holding frame in and out of the .Document loading and removal position move out ·., -.-.; -., -. χ .-.: - ,.: -; '· .-; ·. · ■.-.-. ν '.

It is further. beteits ^ b.ekanntr, with a photographic copier various · document holders. to be provided interchangeably. An example of this kind; is in the German patent 533 8.41. dated August 24, 1928 · described, where two document holders are shown, the · with each other: .by a, joint arrangement in the. Are connected in such a way that -the, forward movement ;, any of the Document holder in the document copy position a similar

Backward movement of another document holder into a document loading and removal position effected. Although the corresponding positions of the two document holders can easily be exchanged, none of the holders can be removed from the copier in capacity on the use of two together associated document holders.

Of course, copiers with more than two have also been made Document holders specified. For example, US Patent 3,488,119 shows a copier in which a first document holder is thereby moved out of a document copying position is that you pull it out manually from the copier. Then the second document holder can eat the by hand Copier can be used for arrangement in the document copying position. One can easily see that this process is very time consuming and an efficient process of copying delayed ..

The invention therefore also aims to design a copying device in such a way that any number of document holders can be exchanged in the device in an efficient manner. The document holder should also be removable from the device.
e

According to the invention, the copier uses a first document holder in a document copying position, while a second document holder is in a document loading and unloading position. Each of these document holders instructs Wedge member on the front part, which can slide under the rear part of another document holder to lift it. In order to exchange the corresponding positions between the first and the second document holder, the second Document holder moved in the forward direction out of the document loading and unloading position, a wedge member of this Do-

kumentenlialters under the back part of the first. Document holder runs and this document holder lifts out of the document copy position. In this way, according to the invention, the first document holder is arranged above the second document holder when the latter is placed in the document copying position. The first document holder is then moved backwards into the document holder and removal position, where this document holder can be removed from the copier and replaced by another document holder. Alternatively, the first document _holder can also., Jf, reload with a new document and then to the front
be moved .. to get back the, place with. the, second document holder. to swap. So all document holders can be exchanged with one another.

(or enclose this surface), and can be moved across this glass plate in mutually perpendicular directions in order to frame surfaces of different sizes with a common center point 1.9 and the documents arranged thereon with different sizes. This feature is shown schematically in Fig. 2, where the rails 15-18, shown with solid lines, frame a specific size area, while the rails shown in dashed lines frame a comparatively smaller area. For the adjustment movement of the rails 1. Each of the guide parts 20 is in one of the four slots, 21, 22, 23 and 24 in the carrier 12. supported and slidably arranged along this. For example, white -. Compare FIG. 2 - the. both guide parts. 20 held in a slidable manner on the holding rail 17 in the slot 23. The two guide parts 20 on the rail 16, on the other hand, are slidably mounted in the slot 24. In addition, the slide are NEN T5 and 16 and -am intersection of the rails 17 and 18 for supporting these rails at the intersections of connecting pieces 25 and 26 in the _{intersection.} In Figure 3 as shown, provided to a Gleitbewegung.der rails in to allow mutually perpendicular directions ^ In order to hold the document 4 on the glass plate 13, the rails 15-18. a plurality of lip pieces 27 attached, -which are shaped such that they are in the manner shown in Fig. 4 partially over the document.

These rollers 28-35 have the same diameter and the same width and can circulate separately. To the movement of the document holder ti in and out of the housing 2 To facilitate out through the access path 10, the copier 1 inside the housing two with parallel spacing arranged guide rails 36 and 37 on; on which the outer scooter 28, 30, 32 and -34 run. As can be seen in Fig. 2, are for reasons that will become clear below., The guide rails 36 and 37 are sufficiently far spaced, around the Outer rollers 28, 30, 32 and 34 "to wear while touching" with the inner rollers 29 ", 31, 3'3 and 35 is avoided., In addition - "as can be seen from Figures 1 and 2 - the Guide rails 3 6 and 37 for holding the document holder "arranged in such a way that when the. document holder

is fully moved into the housing and the document copier division occupies the outer rollers 32 and 34; at two stop pieces 38 and 39 come to rest, with the center 19 of the The area framed by the rails 15-18 is arranged on a main axis of the image projection 40.

The document holder 11 has four locking devices 41 (not all of these locking devices are shown) which work simultaneously and lock the corresponding rails 15-18 in a selected relative position; the locking devices 41 work _: also at the same time when unlocking the corresponding rails so that they can be moved to "change the size of the enclosed" area. (see FIG. 2) the rails 15-18 as a result of the initial movement of the document holder 11 out - .. a document loading and unloading position; on a table 42 of the copier T, into the housing 2 / Fig. 1) In addition, unlock according to the invention the locking devices 41 the rails 15-18 when the document holder 11 is returned from its position within the housing 2 to the document loading and unloading position on the table 42. In the document loading and unloading position, a user can ·

Since the locking devices 41 have a similar structure . Have and require the same mode of operation, only one such device will be described in detail below. Fig. 5 illustrates a locking device 41 in an unlocked position which occurs when the document holder 11 in the document loading and unloading station on Table 42 is located. In contrast, Fig. 6 shows the same locking device 41 in a locking division, which then occurs when the document holder 11 is initially out of the document loading and the removal position is moved into the housing 2. From FIGS. 2, 5 and 6 it can be seen in particular that that this locking device 41 has a channel-forming member 43 which is attached to the frame 12 of the document holder 11 is attached and a.elastisch flexible tongue 44 loosely holds. The opposite ends (not shown) of tongue or tongue member 44 are on rail 17 for common movement with attached, namely opposite the carrier 12. CDie Tongue members of the other locking devices are attached to the corresponding other rails 15-18.) A clamping lever 45 is pivotally mounted on channel-forming member 43 to engage and disengage from tongue member 44 to be able to move. A helical compression spring 46 pushes the clamping lever 45 firmly against the tongue member 44 so as to fix this tongue member against the channel-forming member 43, so that movement of the rail 17 with respect to the carrier 12 is prevented (compare Figs. 2 and 6). When the document holder 11 - how to get out. 5 recognizes - from within the housing 2 is returned to the document loading and unloading position, a wedge or nock block attached to the table 42 pivots 47 the clamping lever .45 out of engagement with the tongue member 44, so that this no longer fixes the rail 17. One recognizes, however from Fig. 6 that, if so, the document holder 11 is initially moved from the document loading and unloading position into the housing

To the first and the. To exchange the second document holder 11 and 11 'in their respective positions in the copier 1, the second document holder is pushed forward through the access path 10 into the housing 2, so that the two frame pieces 48' and 49 'of the second document holder 11 'Push in a corresponding manner against the two rear inner rollers 31 and 29 of the first document holder (compare FIGS. 1, 8, 13 and 14) * As can be seen from FIGS. 8 and 14, this forward pressure is used axif the second document holder II ¹ as the first to attach the rearmost part of the first document holder 11. This is the case because the two front outer rollers 32 and 34 of the first document holder 11 are in contact with the two stop pieces 39 and so that the two ramp pieces 48 'and 49 'of the second Öokuiftentehhalterers Ί1 "wedge-like run under the two rear inner rollers 31 and 29 of the first document holder (Fig. 8, 13 and d 14).

Guide rails 36 and 37 of the copying apparatus 1 in contact, while the four inner rollers 29 ", 35 'and 31', 33 'of the second document holder with the two rails 53 and 54 on the underside of the first document holder 11 are in contact.

When the first and second document holders 11 and 11 'into the are brought relative position shown in Fig. 10, so come the two front outer rollers 32 and 34 of the 'first document holder on two inclined stop fingers 59 and 60 to rest, which in a corresponding manner on the two stop pieces 39 and 38 (see Fig. 2) are attached so that the first Document holder is displaced somewhat opposite the housing 2 into the access path 10. This makes it easy for an operator possible to take the first document holder 11 and aus.dem housing 2 in the manner shown in FIGS pull out. As can be seen from Fig. 10, a depressible snaps Spring pawl or lock 61 behind an edge 62 'on the rear outer wheel 28' of the second document holder 11 ', as a result of the forward movement of the holder 11 'in the Document copying position · inside the housing 2.

In Fig. 17, the masking device 9 according to the invention is in shown individually. The masking device 9 is - as already mentioned - within the housing 2 of the copier 1 between the light source 3 and that of the document holders 11 or 11 ', which is in the document copying position (compare. Flg. 1 ·) is located. The function of the marking device 9 in this case consists of the light source 3 to regulate the amount of light emitted and reflected by the lens 6. 17 shows the masking device 9 in the direction of an arrow 63 in the document copying position within of the housing 2 is moved into the first document holder 11, while the second document holder 11 'is in the document loading and unloading position on the table 42. How one in Fig. T7 recognizes where the marking device 9 is front and rear masks 64, and '65 and right and left masks 66 and 67 on. These four masks 64, 65, 66 and 67 'are thin, opaque plates attached to the front, back, right and left Mask holders or rods 68 or 69 or 70 b ^ w. 71 attached are. The front and rear mask holders 68 and 69 support the front and rear masks 64 and 65 which are in the same Level, spaced from each other, are arranged.
