Description

[Detailed Description of the Invention] This invention relates to an improvement of a file sheet for slides that holds a plurality of slides aligned vertically and horizontally.

When storing a plurality of slides in an organized manner, it has conventionally been common practice to divide the inside of a wooden box vertically and horizontally and insert one slide into each section.

However, wooden boxes have become extremely expensive due to rising material and labor costs in recent years, and are generally bulky and inconvenient to handle.Furthermore, each compartment of the wooden box is usually made up of the thickness of the preparation. Because the depth is several times that of the
It is difficult to search for preparations, and each compartment generally does not have a means to prevent preparations 1 through from being pulled out, so there is a problem that tilting the wooden box causes the preparations to fall out of the compartment.

Therefore, by forming a plurality of relatively shallow rectangular depressions into which the preparations can be inserted in a single plastic sheet, and by making a presser plate protrude inward from the opposing side walls in the length direction of the rectangular depressions. , it was proposed to hold the slides inserted into the recesses by aligning them vertically and horizontally within the same plane.

However, since this type of file sheet was proposed to organize and store only slides of the same size, sampling of the same type of sample can be done by organizing and storing slides of different sizes (for example, l x 31 nch and 3 x 31 nch).
(nch), it is not possible to insert slides into the same file sheet, which causes significant inconvenience in handling and searching slides.

In particular, the present invention places a horizontal bar forming a rectangular recess in the file sheet in the area outside the slide screen area near the holding plate, that is, in the side edge of the slide other than the area where sample sampling is performed on the slide inserted into the file sheet. Only the corresponding parts of the presser plates should be made to protrude upward to the same height, and the other parts of the horizontal bars should be so low that they cannot restrict the movement of the slide inserted into the rectangular recess, or they should be made completely low. By eliminating the above-mentioned high protrusion of the horizontal crosspiece and making it easier to remove it, it is possible to organize and store slides of different sizes relatively easily without reducing the strength of the file sheet, thereby solving the above-mentioned problem. This is an advantageous solution.

Embodiments of the present invention will be described below with reference to the drawings.

A file sheet for preparations 1, which is constructed by press-molding a single plastic sheet, is partitioned by opposing side walls 2a and 3a of vertical and horizontal bars 2 and 3, respectively, and is partitioned into a preparation file 4 (see Fig. 2). ) into which a plurality of rectangular recesses 5 of the same shape can be inserted.

And on the opposite side wall 2a in the length direction of this rectangular depression 5,
A part of it is punched out to form a presser plate 6 that protrudes inward from the upper end of the side wall 2a into the recess 5, while a horizontal bar 3 is placed adjacent to each rectangular recess 5 in the width direction at the center in the length direction of the recess. Interrupting finger depressions 7 are provided to facilitate gripping of the slide 4 inserted into the file sheet 1 in the width direction.

In the illustrated example, grooves 2b and 2C are provided on the vertical bar 2 to strengthen the file sheet 1, and the presser plate 6 is connected to the horizontal bar 3 to strengthen it, but the plastic sheet is sufficiently thick. In some cases, it is also possible to omit the grooves 2b and 2C and disconnect the holding plate 6 and the horizontal bar 3.
A presser plate can also be made to protrude inward from the recess 5 from one side of the opposing side wall 3a of the horizontal crosspiece 3.

In this case, it is preferable that the end of the press plate 6 on the slide inserting side extends slightly downward, as shown in FIG. 2, so that the press plate 6 can hold the slide 4 by its own elastic force.

Further, the vertical bar 2 corresponds to the peripheral part of the bottom wall 5a of the rectangular recess 5, that is, the part outside the screen area of the slide 4 to be inserted.
At a position near , the insertion direction (arrow A
Reference) Two protrusions 5b and 5C that protrude upward are provided at the front and rear, respectively.

In addition, in the present invention, only the portion of the horizontal bar 3 corresponding to the area outside the preparation screen area near the base of the presser foot, up to the position corresponding to the inner edge of the protrusion 5b in the figure, is placed at almost the same height as the presser plate 6. While projecting upward to limit the movement of the preparation in this part, the other part of the horizontal bar 3, that is, the central part in the length direction of the rectangular recess, is made to have a lower height than the protrusions 5b and 5C. To prevent the movement of slides from being restricted.

By doing so, it is possible to make an arbitrary number of rectangular depressions 5 in a row in the vertical direction by cutting out only the shaded portion in the figure with a knife or the like, so that the strength of the file sheet 1 can be reduced when preparing slides of different sizes. It can be easily inserted and inserted without deterioration.

In the illustrated example, the entire diagonally shaded portion of the horizontal bar 3 protrudes upwardly, but by locally protruding highly within that portion,
Resection can also be made easier.

Furthermore, the corner portion of the file sheet, that is, the groove 2b
A positioning member 8 that projects downward is provided at both ends of the finger, and the amount of projection of this positioning member 8 is made larger than that of the finger recess 7.

Therefore, when the file sheets 1 with the slides 4 inserted therein are stacked, the positioning member 8 fits into the positioning member 8 of the file sheet 1 located below and reliably prevents the file sheet 1 from slipping down.

Furthermore, when file sheets without slides 4 inserted therein are stacked, the file sheets can be stored in a compact and regular manner together with the finger depressions 7.

In addition, in the figure, 9 is a ventilation hole that opens downward when forming the presser plate 6, and 10 is a heading part provided on one side of the file sheet, and a symbol, title, etc. can be written on this heading part 10. By attaching the file sheet, it becomes easier to search for the file sheet.
Furthermore, if the file sheet is transparent or semi-transparent, a specific slide in the required file sheet can be easily found by exposing it to light.

Reference numeral 11 indicates a binding hole, and this binding hole 11 can be used to bind and store the file sheet 1 with a fastener with a cover (not shown), and can also be used to fasten the file sheet 1 to a specific fastener. For example, it can be used to store it in a drawer.

In the rectangular depression 5 of the file sheet 1 configured in this way,
Prepara-1 to 4 with normal dimensions (I x 31nch)
When inserting the slide, first grasp the slide 4 from its width direction, place the negative side of the slide between the protrusions 5b and 50 as shown by the dashed line in FIG. is located below the presser plate 6.

Next, the aforementioned one side of the preparation 4 is lifted and adjusted to insert the whole into the recess 5, and under the downward pressing force of the insertion plate 6, the aforementioned one side is placed on the protrusion 5b and the other side. Position the side part on the protrusion 5C (see the dashed dotted line in the second drawing).

In this state, the slide 4 is held between the presser plate 6 and the projections 5b, 5C by the elastic force of the presser plate 6, and the movement of the slide 4 in the horizontal plane is limited by the opposing side walls 2a, 3a. , undesired removal of the slides during handling of the file sheet 1 is effectively prevented.

In this inserted state of the preparation 4, the preparation 4 only contacts the protrusions 5b, 5C and the insertion plate 6, and air flows to the back side of the preparation through the ventilation hole 9, so mold and other moisture can Adverse effects can be prevented, and since the impact on the bottom wall 5a is not directly transmitted to the preparation, cracking of the preparation can be effectively prevented.

On the other hand, when inserting a prepared slide 4a of a different size, for example, 3 x 31 nch, first cut out the shaded portions 3b and 3C of the path, and then cut out one side of the prepared slide 4a in the same manner as described above. By lifting it up a little and inserting it into three consecutive rectangular depressions 5, it can be held securely in the same way as the slide 4.

Note that the reason why rectangular recesses dedicated to slides of different sizes are not provided in the file sheet 1 is because the proportion of slides that are inserted into the slides of different sizes is less than 2%, and the slides of different sizes have 1.5 x 31 nch, 2 X 3
This is because there are various standards such as 1 nch, 3 x 31 nch, etc., and it is difficult and uneconomical to provide a dedicated rectangular depression in anticipation of the required size of the slide.

In addition, when removing the slides 4, 4a that have been inserted, first grasp the slides 4, 4a in the width direction at the 7 finger recesses, and then hold the other end of the slide, that is, the rear end in the insertion direction. It can be easily removed from the file seam 1 by lifting the part against the force of the presser plate 6 to an extent beyond the upwardly protruding part of the horizontal crosspiece 3 and pulling it out in the direction opposite to the arrow A.

Therefore, according to the present invention, a single plastic sheet can be manufactured easily and inexpensively by press processing,
Not only can slides be easily inserted, removed, and searched, but also slides of different sizes can be easily organized and stored on the same file sheet as needed.
