COMPLETE SPECIFICATION FOR THE INVENTION ENTITLED: File sheet for filing information-recording media The following statement is a full description of this invention, including the bciat method of performing it known to me/us:- _J L-

I

The present invention relates to a file sheet for filing information-recording media in which information-recording media having rectangular platelike shape, such as floppy discs or film slides, can be filed and preserved in good order.

j p\or arL Fig. 1A is a plan view showing a e a nven--e file sheet for filing four 3.5 inch floppy discs.

The file sheet 1 is formed of hard plastic by a mold, and in the file sheet 1 are provided four substantially S. 1 0 square compartments 2 which are parted by a frame 3 S, formed along four side edges of the sheet and lateral and longitudinal partitions 4 and The lateral partition 4 is formed in the center portion of the file sheet 1 in the lateral direction to 1 C' 15 separate the file sheet 1 into upper and lower portions 1and the longitudinal partition 5 is formed in the center Sgt portion of the file sheet 1 in the longitudinal direction to separate the file sheet 1 into right and S. left portions. That is to say, each compartment 2 is surrounded by a half of a lateral side 3a of the frame 3, a half of a longitudinal side 3b of the frame 3, a half of the lateral partition 4 and a half of the longitudinal partition 5. The floppy discs are filed in 2 these compartments 2.

In each compartment 2, there are provided two lugs 6, one of said lugs being formed at the center of the half longitudinal partition 5a and the other being formed at the center of the half longitudinal frame 3b.

These lugs 6 are raised from the bottom surface of the compartment. Therefore, when the floppy disc is filed in the compartment 2, it is held between the lugs 6, 6 and the bottom surface of the compartment 2.

In the bottom surface of the compartment 2, are provided two pairs of pad portions 7, 7 and 8, 8, which are raised from the bottom surface of sheet 1. A first pair of pad portions 7, 7, which extend substantially parallel with the longitudinal frame 3b and the longitudinal partition 5, are arranged to be separated from each other by a certain distance in the lateral direction such that the floppy disc is stably supported thereby when it is inserted in the compartment 2 along the side walls 7a, 7a of the first pair of pad portions 7, 7. The second pair of pad portions 8, 8 having their length shorter than those of the first pair of pad portions 7, 7 are formed in alignment with the first pair of pad portions 7, 7.

Fig. lB is a cross-sectional view cut along line lb-lb in Fig. LA. As clear from Fig, 1B, the upper side walls 7b and 7b of the first pair of pad portions 7, 7 are continued to the side of the upper lateral ~1 i \r r t r .r F k 8 P O -3frame 3a. It should be noted that in the lower two compartments 2, the upper side walls 7b, 7b of the first pair of pad portions 7, 7 are continued to the lateral partition 4. The lower side walls 7a, 7a of the first pair of pad portions 7, 7 are inclined with respect to the bottom surface of the square compartment 2. On the other hand, the lower side walls 8b, 8b of the second pair of pad portions 8, 8 are isolated from the lateral partition 4 and both upper and lower side walls 8a, 8a and 8b, 8b thereof are also inclined with respect to the bottom surface of the compartment 2.

y The pad portions 7, 7 and 8, 8 function to hold the floppy disc filed in the compartment 2 in cooperation with the lugs 6, 6. When the floppy disc is to be 16 inserted in the compartment 2, a lower edge portion of the floppy disc is slid down along the inclined side walls 7a, 7a of the first pair of pad portions 7, 7 and is slid up along the inclined side walls 8a, 8a of the i second pair of pad portions 8, 8 via the bottom surface of the compartment 2. The inclination of the side walls 7a, 7a and 8a, 8a are determined such that the insertion of the floppy disc into the compartment 2 becomes easy.

When the floppy disc is extracted from the compartment 2, the extracting is made easy by the 2 inclination of the lower side walls 8b, 8b of the second pair of pad portions 8, 8. That is to say, when the floppy disc is to be extracted from the compartment 2, -4r- :1 the lower edge portion of the floppy disc positioned above the inclined side walls 8b, 8b is pushed down toward the bottom surface of the compartment 2.

Consequently, the other edge portion of the floppy disc, 06 which is positioned on the first pad portions 7, 7, is lifted up. Keeping the posture of the floppy disc, the floppy disc is pushed and slid toward the upper direction and the upper edge portion of the floppy disc rides the lateral frame 3a easily. Thereafter, an operator can pull the floppy disc easily out of the compartment 2. In order to make easy it to insert and extract the floppy disc in and from the file sheet, there are provided half-circle concaved portions 3c in lateral frames 3a, and a central portion of the lateral partition 4 is removed.

Further, in one side flange situating outside of the frame 3, there are formed a plurality of holes 9 by means of which a plurality of file sheets may be bound together.

In theAe nDene azl file sheet 1 described above, however, the upper side walls 7b, 7b of the first pair of pad portions 7, 7 are extended up to the lateral frame 3a or the lateral partition 4. Therefore, when the floppy disc is extracted from the compartment 2, it 2 is impossible to push down the upper edge portion of the floppy disc positioned above the first pair of pad portions 7, 7 toward the bottom surface of the a I

I.

t I I I tc 5 S IS compartment 2. Therefore, in the conventional file sheet i, the floppy disc has to be inserted into the compartment 2 only from the upper side as shown by an arrow 10 which is integrally formed on the bottom surface of compartment 2, and the extracting direction of the floppy disc is also limited to only toward the V upper side, i.e. in the direction opposite to the i inserting direction.

i As stated above, in theean* -Gi~na* file sheet 1 i, the inserting direction and the extracting direction I of the recording medium are limited to only one V direction. Therefore, when binding a plurality of file sheets, the file sheets need be bound only in the same orientation. However, in the file sheet 1, in order to 16 form the lugs 6, holes 6a are provided in a boundary portions between the bottom surface of each compartment 2 and the side wall of the longitudinal frame 3b and in a boundary portion between the bottom surface of the compartment 2 and the longitudinal partition Therefore, when binding a plurality of file sheets 1 one on the other, the lugs 6 formed in the lower file sheet Sare inserted in the holes 6a of the upper file sheet so t t that two file sheets are intimately bound one on the t #other. Fig. 2 is a perspective view showing a case 2 where a floppy disc FD is inserted into one of the compartments 2 in the state that two conventional file sheets 1, 1' are bound exactly intimately on top of each -6 I l-l -7other. That is to say, the floppy disc FD is held between the pad portions 7, 8 formed in the upper file sheet 1 and the lugs 6 formed in the lower file sheet 1'.

In order to avoid that two file sheets are exactly bound to each other, it is effective to bind two file sheets 1 such that they contact each other face to face, and when they are opened in a spread apart manner, so that the two file sheets are arranged side by side. However, in the conventional file sheet, since the inserting direction and the extracting direction of the recording medium are limited to only one direction, when such file sheets 1 are arranged side by side in the spread apart manner, the inserting and extracting directions for one file sheet becomes opposite to those for the other file sheet. In order to avoid such inconvenience, it is necessary to manufacture two kinds of file sheet in which the inserting direction and the extracting direction are made to be opposite to each other so that when the two sheets are arranged side by side, the inserting direction for both sheets may be the same.

A preferred object of the present invention is to provide a file sheet for filing information-recording media, which allows the information-recording media to be inserted into the file sheet and extracted from the sheet in both upper and lower (opposite) directions.

According to a first aspect of the present invention there is provided a file 20 sheet for filing information-recording media, said file sheet comprising a rectangular sheet having a generally flat bottom surface, said sheet having at the following parts formed integrally therewith; a frame formed along each side of the sheet and at least one lateral partition 'and at least one longitudinal partition, said frame being raised from a bottom surface 25 of the sheet by a first distance; t a flange formed outside the frame; I. said at least one lateral partition being raised from the bottom surface of the sheet by said first distance and extending in a lateral direction of the rectangular sheet; said at least one longitudinal partition being raised from the bottom of the sheet by said first distance and extending in a longitudinal direction of the rectangular sheet; 921222,p:\oper\kay,6691 .cla,7

F

-8said frame, said at least one lateral partition and said at least one longitudinal partition dividing the space formed by the frame into a plurality of rectangular compartments for filing information-recording media therein; a plurality of lugs formed in the longitudinal frame section and said at least one longitudinal partition such that at least two lugs are positioned in each compartment, at least one pair of lugs being positioned on laterally opposite sides of the compartment, said lugs being raised from the bottom surface of the sheet by said first distance and projecting over the bottom surface; each of said compartments being provided with first and second pairs of pad portions, raised from the bottom surface of the sheet or the compartment by a second distance smaller than said first distance, said first pair of the pad portions being located such that at least a side of each pad portion remote from said lugs may be positioned in one of two sections of the compartment partitioned by an imaginary i lateral linear zone connecting at least two lugs for the compartment on the laterally opposite sides of the compartment and said second pair of the pad portions being located such that at least a side of each pad portion remote from said lugs may be positioned in the other section of the compartment, each pair of the first and second pairs of the pad portions being laterally opposed to each other and located on the laterally opposite sides of the compartment while being spaced from adjacent respective longitudinal partitions or from adjacent longitudinal partition and adjacent t longitudinal frame section and also being spaced from an adjacent lateral partition or an adjacent lateral frame section, each pair of said first and second pairs of pad portions including the side walls located at a location remote from the lugs which are downwardly inclined toward the adjacent lateral partition or said lateral frame I 25 section, such that a portion of the bottom portion of the compartment may exist between said inclined side walls of the pad portions and the adjacent lateral partition t, or the adjacent lateral frame section.

"1Since the first and second pairs of pad portions of preferred embodiments of the invention are arranged separately from the lateral frame sections and lateral partition, and both upper and lower side walls of these pad portions are inclined, it is possible to lift the edge portion of the recording medium positioned on the first Sor second pair of pad portions up by pushing the opposite edge portion of the 921223,poperkay,669 1.da,8 -9recording medium downwardly, and therefore it is possible to insert and extract the recording medium into and from the compartments in both the upper and lower (opposite) directions. Thus, it is not necessary to manufacture two different kinds of file sheets in order to bind them to be opened in a spread apart manner and it is possible to prevent the stacking of recording medium filed in two file sheets which are bound to each other exactly.

Embodiments of the invention will now be described by way of example only with reference to the accompanying drawings in which:- Figure 1A is a plan view showing the conventional file sheet for filing information-recording media; Figure 1B is a cross sectional view cut along line 1B-1B in Figure 1A; Figure 2 is a perspective view illustrating a state that a floppy disc is inserted 3 in two file sheets which are bound exactly; Figure 3A is a plan view depicting an embodiment of the file sheet for filing information-recording media according to the invention; Figure 3B is a cross sectional view cut along line 3B-3B of Figure 3A; Figure 3C is a cross sectional view cut along line 3C-3C of Figure 3A; i Figure 3D is a side elevational view of a portion S921222,p:\oper\kay,669 .cla,9 i I- -'ii of the file sheet and an index tab; Fig. 4 is a perspective view of the file sheet in Fig. 3A; Fig. 5 is a view illustrating the state in which a floppy disc is being inserted into a compartment in the file sheet in Fig. 3A; and Fig. 6 is a sectional view of the file sheet for illustrating an operation floppy disc from the file sheet in Fig. 3A.

Fig. 3A is a plan view showing an embodiment of the file sheet for filing recording media according to the present invention.

In Fig. 3A, the numerical number 11 represents the file sheet as a whole, 12 and 13 longitudinal frame 16 sections and partition, 14 and 15 lateral frame sections Sand partition. It should be noted that the longitudinal and lateral frame sections 12 and 14 form a continuous frame which extends along four sides of the sheet.

<The file sheet 11 is formed by a mold hard synthetic si 20 resin as a single body. The frame 12, 14 and partitions 13 15 are raised from a bottom surface of the sheet 11 4 by a first distance 6 to 8 mm, so that a space within the frame is divided into four rectangular compartments 16. In the present embodiment, a 3.5 inch floppy disc can be fitted exactly in each compartment 16.

In each compartment, there are provided two lugs 17 and 17, which are formed at center portions of l

I.

the longitudinal frame section 12 and partition 13- The lugs 17, 17 are raised from the bottom surface of sheet by the first distance, so that they are aligned with the top surfaces of the frame and partitions.

In the bottom surface of each compartment 16, are formed a pair of first pad portions 18-1, 18-2 and a pair of second pad portions 19-1, 19-2. All of these pad portions extend in parallel with the longitudinal frame section 12 and partition 13. The pad portions 18-1 and 19-1 are arranged in close vicinity of the longitudinal partition 13 and the pad portions 18-2 and 19-2 are provided in close vicinity of the longitudinal frame section 12.

Furthermore, in the bottom surface of each 16 compartment 16, there are provided two third pad portions 20-1 and 20-2 which are made parallel with the lateral frame sections 14 and lateral partition respectively. The upper third pad portion 20-1 is arranged between the first pad portions 18-1 and 18-2, and the lower third pad portion 20-2 between the second pad potions 19-1 and 19-2, All the pad portions 18, 19 ,I and 20 are raised from the bottom of the sheet by a second distance which is smaller than the first distance. The second distance may be 2~4 mm. When the 2 third pad portions are provided, an additional effect can be obtained. That is, there is the possibility that when the upper or lower side of the information- 'Z(Z 'Il recording medium is pressed down to lift up the other side, this upper or lower side of the medium is downwardly deformed. Particularly when the medium is a slide film fitted on a paper mount, the paper mount will be greatly deformed so that the mount may not be restored. The third pad portions can effectively prevent such an unfavorable phenomenon.

The upper and lower side walls 18-la, 18-2a, 18-1b, 18-2b, 19-la, 19-2a, 19-1b and 19-2b of the first I 10 and second pad portions 18-1, 18-2, 19-1 and 19-2 are inclined. The upper side wall 20-la of the upper third pad portions 20-1 and lower side wall 20-2a of the lower third pad portion 20-2 are also inclined.

The lower inclined side walls 18-lb, 18-2b of the first pad portions 18-1, 18-2 and the upper inclined side walls 19-la, 19-2a of the second pad portions 19-1, 19-2 make it easy to insert the floppy disc in the compartment 16. And, when the floppy disc is extracted from the file sheet 11, the upper inclined side walls 18-la, 18-2a of the first pad portions 18-1, 18-2 and the lower inclined side walls 19-1b, 19-2b of the second pad portion 19-1, 19-2, the upper and lower inclined side walls 20-la, 20-2a of the third pad portion 20-1 and 20-2 make the movement of the floppy disc smooth.

26 That is to say, when extracting the floppy disc from the file sheet 11, first of all, an operator pushes one of the front and rear edge portions of the floppy disc one longitucinal partition such that at least two lugs are positioned in each compartment, at least one pair of lugs being positioned on laterally opposite sides of the compartment, said lugs being raised from the bottom surface of the sheet by said first distance and projecting over the bottom surface; ./2 down, and then the other edge portion thereof is lifted up, and thereafter, the operator can easily slide the floppy disc in an upper or a lower direction to slide out the floppy disc from the compartment 16.

The upper side walls 18-la, 18-2a of the first d pad portions 18-1, 18-2, the lower side walls 19-lb, 19-2b of second pad portions 19-1, 19-2 and the upper side wall 20-la of the third pad portion 20-1 and the lower side wall 20-2a of the third pad portion 20-2 may be formed to be perpendicular to the bottom surface of the compartment 16 when the upper and lower side walls are separated from the lateral frame section 14 and lateral partition 15 by a sufficiently long distance.

Even in this case, when extracting the floppy disc from 16 the file sheet 11, it is sufficient to lift the side portion of the floppy disc up.

Further, in the center portions of the frame lateral sections 14 and lateral partition 15, there are provided concaved portions 14a, 15a in order to make it easy to push down the floppy disc when extracting the floppy disc from the file sheet 11.

t tIn the file sheet 11, is integrally provided a flange 21 outside of the frame 12, 14. In one longitudinal side 21a of the flange 21, there are 26 provided a plurality of holes 22 for binding a plurality of file sheets.

The floppy disc is inserted into the S13 0 ltlL_--L-~i~(fll compartment 16 of the file sheet 11 in the following manner. First of all, one edge portion of the floppy disc is positioned on the lower inclined side walls 18-1b, 18-2b of the first pad portions 18-1, 18-2 or on the upper inclined side walls 19-la, 19-2a of the second pad portions 19-1, 19-2, and thereafter the floppy disc is inserted under the lugs 17, 17 along the inclined side walls by pushing the other edge portion of the floppy disc inside. The other edge portion of the floppy disc is further pushed up or down until the floppy disc is completely inserted in the compartment 6.

The floppy disc is supported between the lugs 17, 17 and the pad portions 18, 19, 20 in a positive manner.

Cut holes 23 are bored under the lugs 17 along boundaries between the longitudinal frame section 12 or the longitudinal partition 13 and the bottom surface of the compartment 16. The upper face of the longitudinal frame section 12 and that of the longitudinal partition 13 are partially depressed at 24 corresponding to locations where the lugs 17 are positioned. As shown, the depression 24 is shaped in the form of a triangle pole, and the inner edge of the depression projects into the cut hole to form a guide member. The guide member is located at the longitudinally central portion of the cut hole 23 under the lug, and so functions that when the information-recording medium is being inserted into the compartment, the corner on the insertion side of the 14 i/medium may be prevented from projecting to the outside of the compartment through the cut hole 23, and the insertion posture of the medium may be gradually corrected (Fig. 06 Extracting the floppy disc filed in the file sheet 11 is effected as shown in Fig. 6. That is, pushing one side portion of the floppy disc positioned in the vicinity of the lateral frame sections or partition .4 or 15 downwardly, the other side portion of the floppy disc is lifted and the floppy disc is inclined by using a fulcrum of edges of the lower side wall 18-lb, 18-2b of the first pad portion 18 or edges of the upper side wall 19-la, 19-2a of the second pad portion 19. Thereafter, said one edge portion of the 16 floppy disc is slid in the longitudinal direction, the other edge portion of the floppy disc rides on the |i lateral partition 14 or 15. The floppy disc is removed from the lugs 17, 17 by further sliding the side portion and pulling it by the operator. As stated above, the pad portions 18, 19 and 20 are arranged so as to make the compartment 16 symmetrical with the lateral center line thereof, so that it is possible to insert and extract the floppy disc in and from the file sheet in either of the upper and lower directions.

S26 Fig. 3B is a cross-sectional view cut along line 3b-3b in Fig. 3A, and Fig. 3C is a cross-sectional view cut along line 3c-3c in Fig. 3A in which the t.LLL.-uii a. -rne rioppy aiscs are riled in r -2inclined side walls of each pad portions 18-2, 19-2, 20-1, 20-2 are illustrated.

At the top 30 of the file sheet 11 are formed two parallel extending projections 32 and 34 on a front side 31 of the sheet 11. Corresponding grooves are formed on the opposite or rear side 33 of the file sheet 11 by the projections 32, 34. Defined between the projections 32, 34 is a channel 36.

Slidably mounted on the top 30 of the file sheet 11 is an index tab 38. The index tab assists in turning of the file sheet 11 and is also suitable for recording media to label the contents of the file j ^r sheet 11.

a The index tab 38, as shown in figures 3B and 3D o is of a C-shaped construction. The index tab includes two side walls 40 and 42 biased towards each other and joined along edge 44. A projection 46 depending from a lowermost edge of side wall 40 is located within channel 36 formed between projections 32 and 34.

A corresponding projection 48 located at the lowermost edge of side wall 42 engages the rear side 33 of the Sfile sheet 11. Since the side walls 40, 42 of the index tab 38 are spread apart from each other by engagement with opposite sides of the file sheet, there is a bias S due to the plastic construction of the index tab 38, to 26 engage in a secure fashion the opposite sides 31, 33 of the file sheet 11.

N

-3- To locate the index tab on the upper edge 30 of the file sheet, the side walls 40, 42 of the index tab are forcibly spread apart using the file sheet as a wedge until the projection 46 is lodged in the channel i 05 36 formed between the projections 32 and 34.

F A similar grooved structure is formed at the V bottom 50 of the file sheet by projections E2, 54 defining channel 56 therebetween. An index tab having a C-shape is similarly located at the bottom 50 of the sheet as is done at the top 30 of the sheet.

For mounting of an index tab on lateral side 58, a projection 60 and an edge 64 of longitudinal side frame partition 12 form a channel 62 therebetween.

Again as with the top and bottom 30, 50, respectively, the projection 46 of side wall 40 of the index tab 38 is slid into the channel 62, while spreading the side walls 42 apart, so as to reliably secure the index tab on I the side 58 of the file sheet 11.

The present invention is not limited to the V 20 above stated embodiments, and many variations may be conceived by those skilled in the art. In the above stated embodiment, four compartments are formed per one file sheet. However, six or more compartments can be formed by increasing the number of the lateral and 26 longitudinal partitions in order to file smaller size recording medium such as slide films.
