A highly successful design provides a box with a plurality of actuators for advancing a web stored on a cartridge within the box to display the information at a viewing window of the box. Commonly, the device is used as a teaching device employing the multiple answer system of teaching and testing. The device operates with advancing apertures on an elongate strip or web which is positioned so that only one of the plurality ofactuating members can engage it and thereby advance the web. In this manner, the correctness or falsity of an answer can be determined.

The commonly owned, copending patent application Ser. No. 100,312 filed Dec. 21, 1970 and Ser. No. 100,313, filed Dec. 21, 1970, now U. S. Pat. No. 3,714,723 for HAND HELD TEACHING MACHINE disclose and claim the above-described device.

The device described and claimed in these patent applications has enjoyed great commercial success and effectiveness in teaching. It is adapted for changing it to various teaching programs and for that purpose provides an interchangeable cartridge. This versatility of the device, however, renders it too costly as a low-cost item that could be used, for example, as a promotional gift by retailers and the like or as a low-cost, disposable item for essentially one-time use.

SUMMARY OF THE INVENTION The present invention provides a low-cost device for displaying a graphic message on an elongate web which has at least one web advancing aperture. Generally speaking the device comprises a rectangular box which has a width and a thickness permitting its manual holding. The box includes a box top and an interior partition located proximate an end of the box which divides the box into a relatively small first web storage compartment and a relatively large second compartment. A plate member is disposed interiorly of the box closely adjacent and parallel to the top and extends from the partition towards the other, remote box end. A space between the box top and the interior plate member communicates with the first compartment and permits advance of the web stored in that compartment to the remote box end through the space between the top and the plate member. Means is also provided for engaging the advancing aperture in the web and moving it from the first compartment towards and past the remote end for the display of the graphic message.

To render the device low cost the box, together with the plate member, the partition, covers for the compartments and the like are constructed of a single folded cardboard sheet and bonded together in their operative position. The elongate web is simply rolled up and placed in the storage compartment and the means for advancing the web comprises snap-on slides disposed in and guided by elongate slots in the box top which are positioned to engage the web advancing apertures.

The device of the present invention is simple and inexpensive to construct and it is made of readily disposable material such as burnable paper or cardboard. It

therefore lends itself ideally for low-cost applications. In addition, the device includes a second storage compartment which can be used for storing any desired item such as promotional literature, product samples or additional rolls of web material. The box has an appealing appearance and can be readily imprinted with advertising matter or the like. The device of the present invention thus ideally supplements prior art graphic display devices of the type disclosed in the above referenced copending patent applications and fills a long felt need.

FIG. 6 is a plan view of a cardboard blank that can be folded into a box for use with the device of the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1 and 4, a device 8 for the display of graphic messages broadly comprises a box 10 including a viewing cutout 12, an elongate web or strip 14 of a flexible material such as paper and one or more web advancing members 16 mounted to the box for engaging the web and moving it in a longitudinal direction past the viewing cutout. The web is of a design similar to that disclosed in the above referenced patent applications, that is, it includes a plurality of picture frames 18 arranged end-to-end over the length of the web. The term picture frame means and includes frames having any type of graphic material such as written material, sketches, paintings, numbers, symbols, and the like.

For each frame the web includes a web advancing aperture 20 located adjacent a frame end or between frames at a fixed, predetermined lateral position on the web. There may be one or more predetermined lateral webpositions for the advancing apertures as is more fully set forth below. For the display device illustrated in FIG. 1 the advancing apertures can be placed at one of two possible lateral aperture positions. This allows the use of the device for teaching by requiring the user to answer multiple choice questions in the same manner as is done with the devices disclosed and claimed in the above referenced copending patent applications. For the mere display of graphic messages, however, only one predetermined aperture location is necessary.

To improve the operating characteristics of the device, that is to improve the ease and accuracy with which the web can be advanced past the viewing cutout, it is preferred that the web advancing apertures 20 be recessed from web edges 22 and located towards a center of the web so that the advancing forces applied to the web are relatively centered with respect to the web width. Undesirable wedging of the web in the box is thereby eliminated.

Referring to FIGS. 1-4, box broadly comprises a bottom 24, a top 26 and interconnecting sidewalls 28. The top includes the viewing cutout l2 and one or more elongate slots 30 which extend from a first box end 32 towards the viewing cutout. Disposed immediately beneath box top 26 is a backup sheet 34 that is parallel to the top and which extends from a second box end 36 towards but short of the first box end. Ends of the backup sheet are free while its sides are connected to sidewalls 28 to form a generally rectangular, thin space 38 that extends from the box interior proximate first box end 32 to about the second box end 36.

A partition 40 is disposed interiorly of the box and is preferably aligned with interior end 42 of backup sheet 34 to divide the box interior into a relatively small web storage compartment 44 and a relatively large compartment 46.

Referring to FIGS. 1, 2, 4 and 6, box 10 is constructed of low-cost heavyweight paper or light cardboard folded from a single cardboard blank 48. This renders the overall costs for the device sufficiently low to make its use as a disposable and/or promotional device commercially feasible. The cardboard has a width equal to the length of box 10 and includes six parallel spaced apart transverse fold lines 50. Going from left to right along blank 48 shown in FIG. 6, where the blank is folded 90 along its fold lines narrow cardboard sections 52 define box sidewalls 28. A first, wide section 54 includes viewing cutout l2 and slots 30 and ultimately defines box top 26; a second wide section 56 ultimately defines bottom 24 of the box, and a third wide section 58 ultimately defines backup sheet 34 of box 10. To space the backup sheet slightly apart from box top 26, the width of narrow sheet sections 52 on each side of wide section 58 is slightly less than the width of the narrow sheet section on each side of wide section 54.

Sheet section 58 also includes two elongate slots 60 (also shown in FIGS. 1 and 2), two short cuts 62 extending inwardly from the edge of sheet 48 distal from viewing cutout 12 and a short fold line 64 connecting the inner ends of the cuts. The length of cuts 62 equals the width of narrow sections 52 adjacent wide section 58 and when the sheet is folded into a box the sheet section 66 defined by cut 62 and fold line 64 is bent down to define partition 40. 7

Assembly of blank 48 into box 10 is conventional, that is it is manually or automatically folded along the fold lines and overlapping sheet sections 52 are secured to each other with staples (not shown), a bonding agent 68 or the like to retain the box configuration.

Covers 70 are provided for closing storage compartments 44 and 46. In the presently preferred embodiment of the invention the covers are also formed from blank 48 by providing corresponding

tongues

72 and 74 as illustrated in phantom lines in FIG. 6. Fold lines are provided between the end of the tongues and the solid outline (in FIG. 6) of the illustrated blank 48. An additional fold line 76 enables the end portion of the tongue to be tucked into the box in a conventional manner.

As an alternative to constructing the covers integral with sheet 48 separate paper, cardboard or plastic snap-on covers (not shown) or the like can be provided. Furthermore, for applications in which the viewing device of the present invention is merely used for viewing and compartment 46 of box 10 is not utilized for storing additional objects, the cover for storage compartment 46 can be deleted. This further reduces the overall costs of the device.

Referring now to FIGS. 1, 2, 4 and 5, web advancing members 16 comprise an elongate, thin flat slide 78 disposed in space 38 between box top 26 and backup sheet 34, a pusher 80 integrally constructed with the slide and protruding through slot 30 and a protrusion 82 on the side of the slide opposite from the pusher. The slide has a width greater than the width of slot 30 and pusher 80 includes a pair of grooves 84, the bottom of which is spaced a distance equal to the width of slot 30. The grooves have a thickness to accommodate box top 26 to thereby secure the web advancing member to the box top and guide it along slot 30 without appreciable lateral motions. The downwardly depending protrusion 82 includes a sloped surface 86 and a face 88 that is perpendicular to the underside of slide 78.

The slide is elongate and protrusion 82 is positioned proximate an end of the slide remote from pusher 80. The web advancing member is preferably constructed of a relatively flexible material such as an injection molded plastic so that the end of the slide fitted with the protrusion can flex up and down with respect to the pusher 80.

Slots of backup sheet 34 (also shown in FIG. 6) are parallel to and aligned with box top slots 30. Slots 60, however, are moved to the right, as viewed in FIG. 5, with respect to the slots in the box top and they have a sufficient width to accommodate the free movement of the downwardly depending protrusion 82 when the web advancing member 16 reciprocates in slot 30. Web 14 is positioned beneath slide 78 in space 38 and the web advancing apertures 20 and protrusion 82 are laterally aligned. Preferably, the protrusion is centered with respect to slide 78 and pusher so that the web advancing aperture is aligned with

slots

30, 60 in box top 26 and backup sheet 34.

The advancing member is readily installed by lifting a portion of box top 26 on one side of the slot and engaging it with one groove 84 on pusher 80. The portion of the box top defining the opposite side of the slot is also raised and slide 78 is wedged into the slot. Thereafter, the box top is released which automatically snaps the web advancing member into engagement with the box top to thereby automatically engage the actuating member with the box top.

In use forward movement of the web advancing member 16, that is movement of the member from first box end 32 towards cutout 12, or movement to the right as viewed in FIG. 4, causes protrusion 82 to snap downwardly when it is aligned with a web advancing aperture. Further movement of the advancing member moves the web forward. The slots are dimensioned so that when pusher 80 arrives at the end of slot 30 proximate to cutout 12 a frame 18 is aligned with, that is fully exposed in viewing cutout 12. The opposite end of the slot is positioned so that return movement of the web advancing member towards first box end 32 moves protrusion 82 at least into alignment with and preferably slightly past the next web advancing aperture on the web. It will be noted that the return movement of the advancing member automatically disengages protrusion 82 from the web since the sloped protrusion glides upwardly on the edge of the web advancing aperture. This deflects slide 78 upwardly until the protrusion clears the aperture. The next frame can be displayed at cutout 12 by again moving advancing member 16 forwardly towards the cutout as described above.

Although the device illustrated in the drawings is shown provided with two web advancing members 16 for certain applications a single advancing member suffices. For example, where the device is used to merely display a series of pictures or photographs, a single actuating member which is preferably centered on box top 26 suffices. For such an application web advancing apertures are centered on the web, that is, the apertures predetermined location is on the web centerline for proper engagement by protrusion 82 of slide 78. For applications in which the user is to make a choice, as for applications in which he is to answer a miltiple choice question by operating one or another web advancing member and in which the correctness of the answer is determined by whether or not the operation of the actuating member actually advances the web, two actuating members, shown in H6. 1, or more (not separately shown) can be provided. They are constructed as described above and positioned side by side. In such instances the advancing aperture for any given frame is aligned with one of the actuating members substantially as described in the above referenced copending patent applications.

Referring now to FIGS. l-6, the device of the present invention is used by rolling web 14 into a roll 90 and placing the roll in web storage compartment 44. The end of the web is threaded into space 38 between box top 26 and backup sheet 34 and pushed forwardly until the first frame 18 is lined up with viewing cutout 12. The actuating members are then retraced towards first box end 32 and cover 70 is closed to securely retain the rolled up web in the web storage compartment. Objects such as additional rolls of web 14, advertising material, product samples or the like can be stored in the other compartment 46 which is also closed with a cover 70.

As mentioned above, the cover can be deleted if nothing is to be stored in compartment 46. When desired the user advances one or the other web advancing member 60 to align a new frame 18 with the viewing cutout. Web issuing from second end 36 of the box can be cut off or diverted into compartment 46.
