Description

The present invention relates generally to

  essentially for the purpose of a device

  slide feeder or the like with an open warehouse guide path for receiving two types of store-binder shaped differently and with indexer or control means in mesh

  with toothed battens transporting the stores-

  filing cabinets, for transport step by step or batch

  intermittent filing stores, in which projec-

  the bottom surface of the storehouse guideway is a seating or support surface for one of the types of store-binder and ramps

  or access are provided for the lifting of the slides

  The invention also relates to the various applications

  cations and uses resulting from the implementation of such a device as well as to systems, assemblies,

  appliances, equipment and facilities with them.

  In a projector of this type, known to the public

  German Examined Patent Application No. 2,827,190, parallel guide grooves for

  guiding a second type of store-binder, are

  in the laterally delimiting walls of the store-guide track or guideway, which guide grooves engage with guide ribs protruding from the longitudinal sides of the store-binder In addition to the guide grooves there are provided appendages Laterally protruding projecting guide in the store-guide track or guideway and constituting a security pocketing the magazine introduced or put in place to fall outside

  or to be removed or removed upward. Such a projection

  only admits the use of a second type of store-

  workbench with a larger basic width, so quite special and store-folders must be inserted by sliding always exactly from the back, in the track or the store-guide guideway,

  parallel to the optical axis of the projection lens.

  A corresponding equipment transformation,

  Existing jets, for so-called "standard" or "standard" lettering stores, are practically impossible.Permanent German patent application No. 2,849,362 discloses a projector with a magazine path or guideway for the receipt of a "standard or standardized" agasin-sorter and a larger width storeroom, the path or guide path of which comprises, along the two longitudinal sides, corresponding steps or steps , through which is formed, over the track or the guide path for the unit store,

  a second wider path or guideway corresponding to

  the width of the second-class filing cabinets.

  The store-binder guide way or guide is open up, so that both types of store-binder are insertable into the projector or can be removed from it without any problem also from the top The projector is also limited only to the use of standard or standardized magazines and larger basemap stores A conversion of normal projector equipment,

  designed for the use of standard or standard

are not feasible.

  The invention is based on the task of realizing a

  jector of the type mentioned at the beginning in such a way that, in addition to a known standard or standard magazine, at least one other, otherwise shaped, stock magazine of the same basic width can be used and also be guided from

  safely, without any construction modifications

  may be undertaken, for the standard or standard

  located on the sides of the magazine path or guideway. This problem is solved in accordance with the invention by the fact that the bearing or seating surfaces for the other type of store-binder are formed by the ramps or climb themselves and they are provided In this way, it is ensured that, in addition to the so-called standard or standard warehouse, and for a reasonable expense, another type of store-storer with the same basic width can be used in a reliable or reliable manner in the same way.

  projector and can be transported in the

  The guiding means may advantageously be provided on each of the ramps of access or of climb, a recess

  or bearing extending parallel to the planar surface

  expensive or in the background, in which case a bar of angular shape

  more than at least one of these bearings or recesses, at least in the middle.

  store-folder are insertable from the top into the

  jector, in which case the other type of store-binder must be placed externally to the angled bar of the ramp or climb According to another advantageous feature, the ramps of access or climb are removably fixed or detachable manner on a base plate or bottom insertable in the store-room guide way or guideway and constitute,

  with this one, an exchangeable or replaceable unit.

  Therefore, it is possible to use, in the projector compliant

  to the invention in a simple manner by exchange or replacement

  placement of the bottom or base plate with access or climbing ramps or even only access ramps

  or climb, other types of store-binder other-

  The invention will be better understood and other purposes, features, details and advantages thereof

  appear more clearly on reading the description of the

  explanatory text which will follow with reference to the attached schematic drawings given solely by way of non-limiting example illustrating a presently preferred specific embodiment of the invention and in which: FIG. 1 is a perspective view of a track

  warehouse guide with two types of store-

  workbook insertable therein, with representation of the slide projector cabinet; FIG. 2 is a cross sectional view of

  The first known file store 16, said standard or standard store, consists of a substantially box-shaped store body which is subdivided between the two side walls by decase partitions 21 and comprises, in the vicinity of the floor or floor, a recess

  22 and a narrow recess 23, substantially rectangular

  Thus are formed three bottom bars 24,25,26 whose bottom bar 24, delimited by the wide recess 22, has a transport lug

toothed 27.

  The second file store 16 'also consists of a substantially box-shaped magazine body 20' with individual box partitions 21 'and has, beneath the lower part of each box partition 21, three bars. Parallel bottom plates 24 ', 25', 26 'between which a wide recess 22' and a narrow recess 23 'are again provided. Here, too, the bottom bar 24', delimited by the wide recess 22 ', has a slat conveyor 27 'The compartment partitions

  21 'are made so as to be transversely elastic

  and at their corners formed by the open sides, hold or retain elements

  which prevent a fall of slides 17 'outside.

  The two file magazines 16, 16 'have the same width at their base. The base or bottom plate 14 of the magazine-file guide path 15 is, as is known, provided with two parallel access ramps.

  The other file store 16 ', intended to be used in the slide projector, differs from the standard or standard magazine 16, not only by a different configuration of the front walls and partitions of case but also in particular in its portion or bottom zone Its recesses 22 ', 23' are of significantly lower height than the recesses 22, 23 of the

  standard magazine 16, in which case the recess 23 'of the magazine-

  binder 16 'is made only in the form of a kind

  In order to accurately guide the file magazine 16 'along the magazine guide path 25, the ramp

  wide access or climb 28 presents, on the side of

  3 as shown in FIG. 3, a recess or bearing 34 and the narrow ramp of access or of rise 29 -presents, at the inner edge, a recess or bearing. On the outer edge of the recess or bearing 35 is provided an angular bar or in the form of an angle plate 36 which extends over only a part of the recess or bearing 35 After the installation of the file store 16 'on the ramps or risers 28, 29 substantially in the vicinity of the bar 36, the latter pass, by his

  horizontal portion, above the bottom bar 26 '.

  Thanks to the conformation of the recess or bearing 35 on access ramp 29 or ramp, there is, on the side or the inner face thereof, a vertical rail 37 which penetrates, by assembly of form, in the recess 23 'while the holding or retaining wedges 32 pass over a marginal rim or an edging rebate 33' provided on the magazine class 16 'is thus obtained, for the magazine 16', a precise guide and without risk or possibility of tilting, in a plane parallel to the movement plane of the standard magazine 16 but however located higher The height position of the recesses or

  34,35 is chosen in such a way that the di-

  17 ', in the file store 16', occupy

  already the correct position in relation to the opening of in-

  slide production 19, so that no raises

is not necessary.

  The access or climbing ramps 28, 29 may be removably or removably connected, for example by screw connection, to the baseplate 14 insertable in the magazine guide guide. The baseplate 14 may also be connected so

  detachable to the bottom element 13, so that it
