OOOOO0Ofi-6u 30333000 0 0 3 30 O0 0000 DOUG DDDUDDUDUD 1 MICROFORM POSITIONING APPARATUS BACKGROUND OF THE INVENTION As is well known, a microform reader includes a light source, an optical system for magnifying a microimage and for projecting the enlarged image onto a screen for viewing thereof, and a microform carrier for positioning the microimage desired to be viewed. The microform holder or carrier has generally included a lower glass plate. secured to a framework, and an upper glass plate, pivotable along the rear edge thereof and operable to receive a microform between the plates, the carrier being movable in both X and Y-directions to en-- able a certain microimage to be rapidly selected for projection onto the screen. The microimages are arranged on a card or fiche in rows and columns, and the microfiche holder is positioned on a table between the light source and the projection lens. assembly'and is slidable across the table by the operator to the desired microimage position. Upon reaching a new position, it is necessary to insure that the microform remain in precise alignment in the X and Y-direction, and it is often necessary to refocus the image in such new position.

While the use of such glass plates, both for containing the microform therebetween and for providing a convenient means of positioning the microform in relation to the projection lens assembly, has been an extremely successful concept in the microform reader industry, it is desirable to reduce the overall cost of the microform units and at the same time to provide a positioning device which assures retention of a desired microimage in a precise position to to be viewed.

SUMMARY OF THE INVENTION The present invention relates to microform readers and more particularly to microform positioning apparatus which includes a series of projections cooperating with a plurality of recesses to position and to retain position of the microform in a desired location. The microform positioning apparatus includes a carrier which has at least one papillaary or fin-like projection, or it may have recess (which projection or recess may also be referred to as positioning marks) respectively cooperating with a corresponding recess or a projection of the table or frame on the reader in a manner so as to enable an arrested position of a particular image de sired to be viewed, and wherein the projection and/or recess corresponds to the location and arrangement of a microimage on the card or fiche.

The structure of the present invention eliminates the need for microfiche carrying glass plates, now in common usage, and hereby provides a microfiche carrier or.

holder which comprises several portions, one of which relates to the microform itself, another of which is the positioning portion secured to the microform, and a third portion utilized as a manipulator or handle for manually moving the carrier across the table of the reader. The positioningportion of the carrier, in a preferred design, comprises a flat sheet orplate having a plurality of projections on the underside thereof, and arranged in a row and column matrix corresponding to the rows and columns of microimages on the microfiche.

A bar or rail extends across and is secured to the table of the reader and such bar includes a groove in the top portion therealong for receiving arow of the projections of the positioning portion of the microform carrier. When a row of the projectionsare seated in the groove, the carrier is arrested from movement in the Y-direction, but is freely slidable in the X-direction under, urging on the part of the operator.

When it is desired to move the carrier in the Y- direction, the positioning portion is lifted slightly by means of the handle portion to free the row of projections from the lateral groove and then such positioning portion is moved to the desired row position where a different row of projections are received by the groove.

After the desired microimage row isattained. the carrier may be slidably moved in the X-direction to obtain the desired microimage column and therefore the de-. sired microimage to be read. i

For sliding of the microimage carrier in the Y- direction and arresting of the carrier in the X-direction, the bar or rail can be turned and similar motions by the operator are used to position the carrier in the desired location.

In view of the above discussion, the principal object of the present invention is to provide microform positioning apparatus which eliminates the use of com.- monly used transparent plates for containing the microform.

Another object of the present invention is to provide microform positioning apparatus of low cost and simple design.

An additional object of the present invention is to provide a microform positioner or carrier which readily slides in one direction and which assures arresting of movement in the other direction.

A further object of the present invention is to provide a microform positioneror carrier which permits visual indication of the location of the microimages, but which also permits registering of the arresting points covered during travel of the carrier from one position to another.

Additional advantages and features of the present invention will become apparent and fully understood from a reading of the following description taken together with the annexed drawings, in which:

In this constructiona pairiof rails 65,- 66 are secured to the table, and extend'in the X-di'rection along the'sides of the positioner portion, each of t the rails having a plurality of grooves 68 'extending across the rail inithe X-dir'ection; for reception of a' row ofthe; projections 37. The grooves 68, are disposed and equally spaced along the length of the rails 65, 66 to an;

Additionally, the row of projections 37 illustrated in FIG. 9 could be substituted by a single fin-like projection extending across the member 39 and on the underside thereof. A different arrangement of such fin-like projection is illustrated in FIGS. 11 and 12 wherein a positioner memberr 75 in the nature of a solid piece of plastic material is formed with a pair of fin-like bars 76, 77 on the underside thereof to mate with grooves 78 in a corresponding member 79 on the table 20. In this arrangement the positioner is meant to be arrestable in the X-direction and easily slidable in the .Y-direction. Of course, the bars 76, 77 could be formed 90 degrees from that shown for arresting the positioner in the Y- direction.

Further modifications can be conceived wherein the microform is not placed'within an envelope but is directly attached to asingle plate having a matrix of projections corresponding to the rows and columns of microimages and positionable in the X or the Y direction.

Additionally, the table could carry a bearing plate under the positioner portion, such plate having a plurality of recesses therein arranged in matrix fashion and having connecting grooves therebetween for receiving of bars or rails formed on the underside of the positioner portion. This arrangement is similar to that shown in FIG. 12, but with slightmodifications to implement the connecting grooves. It is also possible to arrange the positioning marks, whether projections or recesses, directly on the microform or microfiche wherein such marks could be located between the microimages and be received by corresponding marks in the bearing plate 28.

It is thus seen that herein shown and described is a microform positioning apparatus of low cost and of simple design to provide arresting of the microform in a desired location, while permitting ease of movement to another location. The invention eliminates the need for the upper and the lower plates now commonly used for retaining the microform and also the complex carrier structure for moving the microform in the X and Y-directions. The apparatus enables the accomplishment of the objects and advantages mentioned above, and while several embodiments of the invention have been disclosed herein, certain other variations may occur to those skilled in the art. It is contemplated that all such variations, not departing from the spirit and scope of the invention hereof, are to be construed in accordance with the following claims.
