Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mount for an overhead projector film, which is used to facilitate handling of the overhead projector film.

[Prior Art] As is well known, overhead projectors are widely used at various meetings such as briefing sessions and lectures. In this overhead projector, transparent films with characters, figures, etc. written on them are sequentially placed on a document table above a light source, and the written contents are projected onto a screen.

This type of projector often uses film without any type of reinforcement or shape retention, but simply using film alone is difficult to handle during explanations or storage, and there is a risk of bending or damage. Not only is this easy to cause problems, but it also takes a long time to search for a desired film.

For this reason, it is widely practiced to attach the peripheral edge of the film to a frame-shaped mount made of cardboard or the like so that the mount and the film can be handled as an integrated unit.

Incidentally, at present, such overhead projector film mounts are formed into a frame shape at a factory, and then delivered to users as they are through the distribution stage. That is, conventionally, an article called a mount for an overhead projector film has a frame shape with a transparent window inside.

[Problem that the invention aims to solve] However, during the manufacturing stage of mounts with this shape, a large amount of chips corresponding to the transparent windows are generated, which complicates the processing process and requires equipment. tends to be large-scale. Another problem is that frame-shaped mounts tend to deform due to gravity and external forces when stacked, packaged, and transported. In other words, if non-square frame-shaped mounts are stacked at different positions or in different directions, the frame of the upper mount may be located on the transparent window of the lower mount, and the upper mount may easily deforms into a shape that invades the transparent window due to gravity.
Furthermore, even if all the mounts are stacked and packed in the same position without shifting, if an external force is applied to the packaged items from the side, the mounts in the area where the external force is applied tend to deform inward. .

Furthermore, it is not uncommon for characters and figures to be written freehand on this type of film, but the conventional mounts described above do not have a guide function that is useful for writing. Therefore, the problem remains that it is difficult to create a film original with a well-balanced arrangement.

Furthermore, when explaining using a large number of film manuscripts, it is necessary to
It is common to set the items in the overhead projector in order, starting from the top, and then remove the items that have been explained from the projector and stack them face down so that the order is not reversed. Another problem is that it is relatively difficult to search for a used film if it becomes necessary to use it again. In other words, when searching for a desired film in the middle of an explanation, etc., it is normal to mainly visually check the written contents of the film, but if there are many transparent films overlapped, it may be difficult to find the desired film. There is also the problem that the written content on the side film and the written content on the upper film overlap, making it very difficult to visually recognize them.

The present invention aims to solve the above problems.

[Means for Solving the Problems] In order to achieve the above objects, the present invention employs the following configuration.

That is, the overhead projector film mount according to the present invention includes a frame-shaped mount body for holding the edge of the overhead projector film, and a frame-shaped mount body that is integrated with the inside of the mount body through a separation line. It is characterized in that it is provided with a grid mount part which is provided on one side and has grid lines on one side.

[Function] With this structure, the part that was conventionally discarded as the largest scrap at the manufacturing stage becomes a part of the product as the grid mount, so it can be The burden required to dispose of chips is reduced.

Moreover, since each of these mounts is in the form of a single plate-like body without a transparent window, no matter how they are stacked, they will back up each other from above and below. Therefore, deformation due to gravity is less likely to occur. In addition, the grid mount part of each mount also plays the role of preventing the corresponding mount body from deforming inward, so even if external force is applied from the side to a package made of multiple mounts stacked, it will not easily deform. Become something.

By the way, in the overhead projector film mount having such a structure, the grid mount portion can be separated from the mount main body via the separation line. Therefore, normally, the grid mount part is completely separated from the mount main body, and a film is pasted to the frame-shaped remaining mount main body in the conventional manner.
In that case, since grid lines are applied to one side of the grid mount part, before separating the grid mount part from the mount body, the film before being pasted is superimposed on one side of the mount, and the grid lines are applied to one side of the grid mount part. You can write characters, figures, etc. on the film using the as a guide. Furthermore, it is also possible to draw a draft on the grid ruled area in advance with a pencil or the like, and then trace the draft onto a film stacked thereon.

Note that this mount can also be used without completely separating the grid mount portion from the mount body. That is, if a part of the separation boundary line is left in a stretched state, that part becomes a hinge, and the grid mount part can be opened and closed like a door with respect to the mount body. Therefore, if the grid mount section is placed so that it can be opened on the front side, and a film is pasted on the back side of the mount body, it can be used in the following manner. That is, when setting it in an overhead projector, the grid mount section is left open. When the projector is removed from the overhead projector and placed on a desk or the like, the grid mount section is closed. By doing so, only the matters written on the film in front of the grid mount section can be read.
It becomes possible to clearly see the film, and the film underneath is shielded by the grid mount section. Therefore, it is convenient when searching for and reusing a desired item from mounts stacked on a desk or the like.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 to 5, this overhead projector film mount has a grid mount portion 2 on the inside of a mount body 1, and a border line 3 for separation.
It was established through the

The mount main body 1 is frame-shaped, and on its surface 1a, for example, as shown in FIG.
14 is printed.

The grid mount part 2 has a shape corresponding to a conventional transparent window,
That is, it has a rectangular shape, and grid rules 21 are printed on its surface 2a, as shown in FIG. As is clear from the drawings, the grid mount section 2 and the mount main body 1 are constructed flush with each other using a common material. In other words, this mount is made by cutting the cardboard.
The mount main body 1 and the grid mount section 2 are integrally constructed, and the separation boundary line 3 includes a cut line section 31 where the material is completely separated, and a short integrated section where the material is not separated. It consists of a continuous part 32. The integral continuous part 32 is formed by leaving a part of the material uncut, as shown in the drawing.
The grid mount section 2 can be separated from the mount main body 1 by applying a shearing force in the thickness direction to break the integral continuous portion 32.

With this configuration, the part that was conventionally discarded as the largest scrap during the manufacturing stage will now form part of the product as the grid mount 2, making it easier to dispose of the scrap. The required burden is reduced. Therefore, it is possible to simplify the manufacturing process and equipment.

In addition, each of these mounts is in the form of a single plate-like body without transparent windows, so even if they are stacked at different positions or 90 degrees apart,
They support each other from above and below. Therefore, unreasonable force due to gravity is not applied to each part. In addition, the grid mount part 2 of each mount
also plays a role in preventing the corresponding mount main body 1 from deforming inwardly, so even if an external force is applied from the side to a package made of a large number of mounts stacked up, it will not easily deform. Therefore, it becomes easy to provide users with an excellent product with little deformation.

Furthermore, in the overhead projector film mount having such a structure, the grid mount portion 2 can be separated from the mount main body 1 via the separation line 3 by, for example, the above-mentioned shearing operation. Therefore, at the stage of use, as shown in FIG. 6, the grid mount section 2 can be completely separated from the mount main body 1, and the film 4 can be pasted to the mount main body 1 remaining in the frame shape in the conventional manner. . In that case, since grid lines 21 are provided on one side 2a of the grid mount section 2, before separating the grid mount section 2 from the mount main body 1, the film 4 before pasting is placed on one side of the mount. By superimposing them, characters and figures can be written on the film 4 using the grid lines 21 as a guide. It is also possible to draw a draft on the grid line 21 in advance with a pencil or the like, and then trace the contents of the draft onto the film 4 placed thereon. Therefore, parts that were conventionally discarded during the manufacturing stage can be effectively used as an underlay with grid lines 21, and a well-balanced manuscript can be created without using special drafting tools or grid paper. It becomes possible to create.

This mount can also be used without completely separating the grid mount section 2 from the mount main body 1, as shown in FIG. That is, a part 3a of the separation boundary line 3 corresponding to one side of the grid mount part 2
If the portion 3a is left uncut, the portion 3a becomes a hinge, and the grid mount section 2 can be opened and closed like a door with respect to the mount main body 1. Therefore,
For example, as shown in FIG. 7, the grid mount section 2 can be opened on the front surface 2a side, and the peripheral edge of the film 4 is pasted on the back surface 1b of the mount main body 1. It can be used like this. That is, when setting it in an overhead projector, the grid mount section 2 is left open. When the projector is removed from the overhead projector and placed on a desk or the like, the grid mount section 2 is closed. By doing so, it becomes possible to clearly see only the matters written on the film 4 located in front of the grid mount section 2, and the film 4 below is
It will be shielded by Therefore, it is convenient when searching for and reusing a desired item from mounts stacked on a desk or the like.

It goes without saying that the film may be attached to the front surface of the mount if necessary.

[Effects of the invention] Since the present invention has the above-described configuration, it is possible to easily and significantly reduce the generation of chips during the manufacturing stage, simplifying the processing process and simplifying the equipment. In addition, it can effectively prevent deformation during packaging and transportation, and when in use, it is possible to write letters and figures on the film in a well-balanced manner using the grid rules of the grid mount. In addition, by devising the manner in which the grid mount portions are separated, it is possible to provide a mount for an overhead projector film that can facilitate searching.
