Description

[Detailed Description of the Invention] This invention relates to a slide file sheet for magic lanterns in which a plurality of file sheets for fitting and accommodating several slides for magic lanterns and an exchange card section can be freely connected.

Conventionally, this kind of magic lantern slides were used at presentations and briefing sessions, where slides that each person presented were placed in a storage frame of a file sheet divided into 10 sections in the longitudinal direction by each presenter or other person concerned. Stored in numerical order,
This is to be entrusted to the slide staff. However,
If this file sheet is somehow turned upside down and the slides inside pop out, the order will be thrown out of order and it will be a difficult task to arrange them in numerical order.

In addition, the conventional slide file sheet has two windows facing each other on a single piece of paper in the longitudinal direction.
Usually, the frame of the base paper is placed between the window and the window.
The frame that holds the 10 magic lantern slides is made continuous by pasting or folding it with a metal frame, etc. In this case, the file sheet has a drawback that the slides can easily come off or jump out, since each slide is simply inserted into the file sheet through an insertion hole opened on the top surface.

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

This invention solves these conventional drawbacks, and its main purpose is to allow the file sheet to be divided and assembled freely, making it easy to transport and store, and to ensure reuse. can be done,
Moreover, it is made of synthetic resin and can be mass-produced. Furthermore, each magic lantern slide is prevented from easily flying out or detaching from the file sheet. The main structure is that each of the plurality of file sheets is connected to each other by providing a removable engaging portion at one end thereof. Moreover, a removable connection part is provided at the other end of one of the sheets to connect an exchange card part.

Next, an embodiment of this invention will be described with reference to the drawings.File sheets 1 and 2 for slides which are connected adjacent to each other are divided into five sections and molded with synthetic resin. 3 is the exchange card part, which is made of a synthetic resin plate. 4 shows various magic lantern slides. One end of the file sheet 1 has the exchange card 3 in which the presentation title, number, number of sheets, affiliation, name, etc. written on the connecting part 15.
The other file sheet 2 is connected to the other end by a connecting part 5. Next, the file sheets 1 and 2 are provided with storage frames 6 and 6 adjacent to each other, into which five magic lantern slides 4 and 4 are inserted from above. The storage frames 6, 6 are provided with see-through windows 9, 9 in the center front, and rectangular insertion holes 7, 7 into which the slides 4 are fitted from above.
In this storage frame 6, pressing protrusions 10 for crimping are formed on both sides or one side of each storage frame 6, which protrudes inwardly toward either the front or rear of the vertical frame 8 corresponding to the left or right. It has been done. Furthermore, file sheets 1 and 2
The edge 1 of the file sheet 1 is connected to the connecting portion 5 with the
An engaging portion 12 protrudes from the file sheet 2, and a locking recess 14 is formed in the edge 13 of the file sheet 2 to be removably fitted into the engaging portion 12. The exchange card portion 3 connected to the end of the file sheet 1 is provided with an engaging protrusion 19 on its connecting portion 15, and is removably fitted into a groove 20 provided on the other end of the file sheet 1. It's starting to match. In addition, card parts 17, 17 are formed on the left and right sides of the exchange card part 3, with a cutout part 16 located approximately in the center as a border. code 18
are anti-slip uneven portions provided on the pressing protrusion 10.

This device is constructed as described above. To explain how to use it, the file sheets 1 and 2 are connected at the connecting portion 5 by the engaging portion 12 and the locking recess 14, and the connecting portion 15 at the other end of the file sheet 1 is connected to the connecting portion 15.
The exchange card section 3 is connected by the engagement of the engagement protrusion 19 and the concave groove 20. The slides 4, 4 arranged in numerical order in the accommodation frame 6 of the sheets 1, 2 are connected to each other.
When the vertical frame 8 is inserted between the insertion holes 7, 7, the pressing protrusions 1 on the inner surface of the vertical frame 8 are pressed against each other.
The slides 4, 4 are firmly held in the housing frame 6 by the fasteners 0. After use, the file sheets 1, 2 can be detached at the connecting parts 5. Also, a part of the exchange card 17 can be detached or left attached, and either can be disassembled into short pieces for easy storage and easy reconnection for use.

As mentioned above, this idea is that if the magic lantern slides are fitted and housed in each storage frame of each file sheet, they will not come off unless the sheet is turned over or tilted. , it can be used with confidence, and when used, it can be quickly assembled and used by connecting each file sheet containing slides and the exchange card section with the presentation title, name, etc. written, and is extremely efficient. It has a good effect. Furthermore, since the exchange card section is divided, it is very convenient for use at venues and the like. After use, each file sheet and the exchange card section can be easily separated, resulting in a significantly smaller size, which has the practical effect of being extremely convenient for storage and transportation. By making the file sheet and the exchange card part made of synthetic resin, it is suitable for mass production, is inexpensive, and does not bend or deform like conventional base paper. It has the effect of making you tougher without making you feel sad.
