Description

[Detailed Description of the Invention] This invention relates to a magic lantern slide file case in which several magic lantern potine negatives are fitted and housed for use in slide projection.

Conventionally, this type of magic lantern slide was used to store magic lantern potion negatives brought by each person at each venue of an information session or presentation in each storage frame of a file sheet divided into 10 sections in the longitudinal direction. The person concerned stores the slides in numerical order and entrusts them to the slide staff. However, if this file case is somehow turned upside down and the slides inside pop out, the order will be thrown out of order and it will be very troublesome to arrange them in the numerical order of the explanation order. In addition, the conventional slide case has a transparent window facing opposite to a sheet of base paper in the longitudinal direction, and a frame of the base paper is interposed between the window and the window to accommodate 10 magic lantern potine negatives. It is continuously formed by pasting or folding a housing enclosure frame with a metal holding frame or the like. In this case, since each magic lantern slide is simply inserted into the film case through an insertion hole opened on the top surface, there is a drawback that the slide can easily come off or pop out.

Furthermore, because the conventional slide file case has 10 magic lantern slides arranged horizontally, it is difficult to carry the slides after each slide due to their long length. Extraction,
This method has disadvantages such as being very uneconomical since used sheets are discarded.

This invention improves on the above-mentioned conventional drawbacks, and its main purpose is to make the file case easy to disassemble and assemble, making it easy to transport and store, and to make it easy to reuse. It is reliable and made of synthetic resin, making it possible to mass produce it. Furthermore, the magic lantern potine negatives are prevented from easily popping out or detaching from the file case. The main structure is that in the file case made of synthetic resin in which the magic lantern potine negative is stored, several storage frames are provided in the file case, and the opposite horizontal frames of the storage frames are At least one side is provided with a protrusion for pressing a magic lantern potion negative.

Therefore, according to this invention, there is an effect that each magic lantern potine negative does not easily jump out or come off from the file case, and it is very convenient to divide, transport, store, etc.

Next, one embodiment of this invention will be explained with reference to the drawings. Reference numerals 1 and 1 are file cases for slides that are connected adjacently, and the file case 1 is made by polymerizing two opposing sheets molded from synthetic resin. It is formed by 2 indicates an exchange card detachably connected to the edge of the file case 1;
1 shows a magic lantern potine negative fitted into the file case 1. Said file case 1
The storage frame 4, 4, . . . is constructed into five compartments with longitudinal partition walls 8, 8 for partition inside. A see-through window 5 is provided in each of the housing enclosure frames 4 at the center front thereof. A rectangular insertion hole 10 into which the magic lantern potine negative 3 is fitted is formed in the upper part of the see-through window 5. Further, on one or both of the opposing upper or lower horizontal frames 6, 6 of the housing enclosure frames 4, 4..., a protrusion is formed by various means for pressing the outer periphery of the magic lantern negative 3. 7, 7... are formed respectively. Next, in the file case 1, there is a file case 1 adjacent to the vertical frame 9 located at one end of the file case 1.
A vertical engaging protrusion 11 is formed to connect the file cases 1 to each other, and a locking recess 12 to connect another file case 1 is formed on the other end. Also,
The exchange card 2 includes the title, number, number of sheets,
Card parts 14, 14 where you can write your affiliation, name, etc.
are formed, and one or several cut-outs 13, 13 are formed in the card parts 14, 14. At the end of the card portion 14, a vertical engagement protrusion 1 that can be freely engaged with and disengaged from the engagement recess 12 is provided.
5 is formed as a protrusion. Reference numeral 16 indicates a connecting portion between the file case 1 and the exchange card 2, and 17
is a bulletin board provided in the horizontal frame of the storage frame 4 for writing the presentation title and the like.

This invention consists of the above-mentioned configuration, and in order to use this file case 1, the file case 1 must be
and 1 are engaged and connected by the engagement protrusion 11 and the locking recess 12 at the ends, and the exchange card 2 is engaged with one end of the file case 1.

Then, when the magic lantern potine negatives 3, 3... are inserted into the housing frames 4, 4, . The negatives 3, 3 are firmly fixed within the housing frame 4 and can be used in a state where they will never come off.

Next, when the sliding is completed, if the file cases 1 and 1 are disengaged from the above-mentioned engagement connection, each file case 1 becomes short, so it can be stored as is, and if it is connected, It can be easily used again.

Incidentally, it goes without saying that one file case 1 can be used as is.

As described above, according to this invention, the magic lantern potine negative once inserted into the file case will not easily escape unless it is manipulated even if it is turned over, making it very convenient to use and It has the practical effect that it can be easily separated and miniaturized later, making it very convenient to store and transport.
Since the file case is made of synthetic resin, it is suitable for mass production at a low cost, and it is extremely strong without having to worry about bending or deforming as with conventional cardboard. effective. In addition, the protrusions provided on one or both of the opposing horizontal frames of the housing enclosure act elastically when the magic lantern potion negative is inserted, ensuring secure pressure contact and firmly clamping, so there is no problem such as easy popping out. There are also excellent practical effects in terms of manufacturing, such as the fact that there is no need for any problems, and the protrusion can be easily molded in one piece.
