I v

r The subject matter which I regard as my invention. is particularly pointed out and distinctly claimed in the including portion of this specification. The invention, however, both as to organization and method of operatiom together with further advantages and objects thereof, may best be un- "tends'to' bow downwardly inasmuch

aswall portions

32a and 32b bo'w outwardly or downwardly toward opening 36.

The folded ends of the tape are generally perpendicular to end

walls

24 and 26, with the latter' supporting oneset of folded ends. Thelon'g wallsof the receptacle are also desirably disposed at an angle to the horizontal such that the receptacle extends diagonally upward from end wall 26. as shown, whereby wall 26 is other than horizontal but whereby the receptacle isfmost advantageously accommodated in the minimum amount of panel space for a given length of tape fold. In order to reduce further the space occupied bythe I receptacle,'and in order to enhance the bow of the tape folds toward outlet opening 36. upper end wall 24 is desirably horizontal rather than being parallel to lower end wall 26.

The tape. in passingthe reading station comprising reading head 12. is guided between a first guide means38 and a j I second guide means 40, wherein the latter guide means is on the opposite side of

rollers

16 and 18 fromreading head 12 derstood by referenceto the following description taken in connection vwith the accompanying drawings wherein like reference characters refer to like elementsl-- I and adjacent inletopening 34. The guide means 40 is desirably adjacentand just above the lower 'wall' portion 30b of the receptacle. Guide means 38 and 40 suitably comprise rollers or spool-shaped cylindrical pins which may or may not rotate, and which have beveled end portions for guiding the tape along the desired path. The wall portion 30b iscurved outwardly under guide means 40 for receiving and guiding a' downwardly extending fold of tape into the receptacleas will be seen in FIG. 4. Similarly, wall portion 30a is curved outwardly from the receptacle above guide means 40 for guiding an upwardly extending fold of tape into the receptacle as illustrated in FIG. 1.

The tape in leaving receptacle 22 is withdrawn around a third guide means 42 adjacent outlet opening 36, and specifically adjacent wall portion 32b of the receptacle. The latter guide means is desirably closely adjacent wall portion 32b. and hence the upper edge thereof defines an effective opening width, a, for outlet opening 36, the opening being smaller than it would be in the absence of guide means 42. From guide means 42 the tape passes under the receptacle and around an external or fourth guide means 44 comprising a metal wall, curved into a large radius, and secured to panel 10. From guide means 44 the tape 20 proceeds back over guide means 38 to the reading station.

A curved guide wall 46 extends wall portion 32a, i.e. the wall on the opposite side of the outlet opening 36 from guide means 42. Guide wall 46 opens curvilinearly outwardly of the receptacle in spaced relation around guide means 42 to a position coincident with a lower horizontal guide platform 48 pe rpendicularly secured to panel 10. Note that guide wall 46 smoothly continues the outward bow of wall portion 32a at an increasingly larger angle until guide wall 46 starts curving around guide means 42 in spaced relation thereto. Guide wall 46 in effect extends the outlet opening and provides a guide for accommodating and directing unfolding bowed loops of tape. It has been found that the effective width, 0, of the outlet opening should be at least approximately 1% inches, such that the tape does not become pinched or distorted as it is withdrawn from the receptacle. In a specific example of the present invention, four-mil tape was employed. For thinner tape, a somewhat smaller opening may be usable. Since guide wall 46 extends the opening, curving around guide means 42, the width, b, which is also effectively the width of the outlet opening, should likewise be no smaller than the above criteria.

It is additionally found that the effective width of the outlet opening should not be greater than approximately one-half the length of a fold of tape, or of the dimension of the receptacle between

walls

24 and 26, whereby more than one fold of tape will not lower from the receptacle without being withdrawn therefrom. It should be noted that while these dimensions are important, they are none the less rather approximate. That is. tape should be withdrawable from an opening of sufficient size to avoid creasing or deforming the tape, while the opening is not so large that more than one fold of tape is accidentally withdrawn. Both the outlet opening 36 and the inlet opening 34 should be approximately centrally located in the respective long walls of the receptacle.

Also, guide means 42 should have a radius of curvature of approximately three-eighths of an inch to prevent creasing or deforming of the tape, i.e. it should have a diameter of threequarters of an inch or more, when, for example, 4-mil paper tape is employed. This dimension is likewise somewhat ap proximate. Furthermore, it is desirable, but not necessary, that guide means 42 be cylindrical. Such guide means may, for example, be octagonal or have some other shape approximating a curve of sufficient radius such that creasing or deforming of the tape does not take place as the tape is withdrawn therearound.

FIGS. 1 through 7 illustrate operation of the apparatus according to the present invention, showing the tape in various successive positions. FIG. 1 illustrates a first position of the tape wherein the plurality of folds 28 are housed within receptacle 22. Tape 20 passes around guide means 42 as indicated and rests upon platform 48, then passing around guide means 44, and so one. In FIG. 2,

rollers

16 and 18 have pulled tape 20 a little farther for withdrawing the top crease or end of the last fold from the top of the receptacle. In the process, the next to the last fold, 50, protrudes outwardly through opening 36. forming a small loop in so doing. However, the dimensions a and b (see FIG. I). are large enough so that the tape does not become folded or deformed at other than the desired locations where it is already folded.

In FIG. 3, the next to the last fold 50 is further withdrawn with the last fold being guided along guide wall 46. In FIG. 4. fold 50 has popped" to the right, with fold 50 now becoming the last fold. which is about to be withdrawn around guide means 42. In FIG. 5, the tape 20 is taut around guide means 42. Then. as illustrated in FIG. 6, the now next to the last fold 52 bows outwardly along guide wall 46, as a lower end crease is pulled up from the bottom of receptacle 22. Thus. each fold of tape as withdrawn from receptacle 22 causes the next fold of tape to bow from the outlet opening 36 with sufficient curvature to avoid deforming the tape. Guide wall 46 accommodates or guides unfolding loops of tape in the illustrated embodiment. In FIG. 7, the lower end crease has been pulled around guide means 42. As tape 20 is withdrawn further, the next position of the tape is illustrated in FIG. 1. It will be noted that the tape has been withdrawn in a manner to retain the initial folded condition thereof without imparting further distortion. lfsuch were not the case, the tape would not rcfold when reintroduced through inlet opening 34.

The entrance of the tape into the receptacle will now be considered. Starting with FIG. I, it is noted the incoming tape has its top crease guided up along wall portion 30a. Then, in FIGS. 2 and 3, the tape is bowed inwardly, laying down a fold of tape 54 within the receptacle. In FIG. 4, as fold 54 is substantially within the receptacle, wall portion 30b acts as a fair lead for guiding a next fold of tape, 56, into the proper location at the lower end of the receptacle. As illustrated successively in FIGS. 5, 6. and 7, fold 56 is further guided into the receptacle until an upper crease thereof is adjacent wall portion 30a as seen in FIG. 7. The fold 56 is guided substantially completely into the receptacle along the other folds 28 as further viewed in FIGS. 1 and 2.

While the apparatus according to the present invention is particularly efficacious for handling a closed loop of tape, it will also be appreciated that the same apparatus may be employed for fanfold tape where the beginning of the tape is not connected to the end. In such instance, the tape is fed through the station comprising reading head 12 and into receptacle 22 where it may be stored until needed. Then, the start of the fanfold tape may be withdrawn from exit opening 36 and fed through the reading station once again. A writing mechanism for punching holes in the tape may obviously be substituted for reading head 12 if so desired. It should also be noted the system according to the present invention requires no power in addition to that provided by the tape drive to

rollers

16 and 18 associated with the reading or writing station.

While I have shown and described a preferred embodiment of my invention, it will be apparent to those skilled in the art that many changes and modifications may be made without departing from my invention in its broader aspects. 1 therefore intend the appended claims to cover all such changes and modifications as fall within the true spirit and scope of my invcntion.
