Description

  The present invention relates to a shaukasten used for reading an X-ray film, a photographic film, and the like, and a film fixture used for the shaukasten.

  Shou-Kasten is a device used mainly for reading X-ray films, photographic films, etc., and is fixed inside a semi-transparent acrylic plate surface as a light irradiation surface with a film fixing tool and built in the device body. The film can be read by applying a backlight to the film from a translucent acrylic plate with a light source.

In such a conventional shaukasten, a film is fixed by a film fixture 60 as shown in FIG. The film fixing tool fixes the film 63 by being sandwiched between the stainless steel pin 61 and the translucent acrylic plate 62 by the weight of the stainless steel pin 61. Further, by pulling the film in the front direction F (normal direction of the translucent acrylic plate), the stainless steel pin 61 is rotated, and the clamping between the stainless steel pin 61 and the translucent acrylic plate 62 is released. The fixed film 63 can be taken out. In addition to such pins, a film is fixed by a holding piece obtained by bending a small piece of a polymer film into a V shape (for example, see Patent Document 1), and a film is fixed by an elastic brush. (For example, refer to Patent Document 2).

  However, the conventional shaukasten has the following problems.

  That is, in recent years, with the diversification of films, the thickness, weight, and surface friction coefficient vary. When a stainless steel pin is used for fixing the film, depending on the weight of the film and the friction coefficient of the film surface, the film may fall without being supported by its own weight. Furthermore, when using a stainless steel pin to fix a film on a semi-transparent acrylic plate with irregularities, it cannot be pressed against the semi-transparent acrylic plate with equal strength. For example, the film may be fixed horizontally. It may not be possible, or one end of the film may fall along the way.

  In addition, even when the film is fixed with a holding piece obtained by bending a small piece of polymer film into a V shape or an elastic brush, when the weight of the film or the coefficient of friction of the film surface is not suitable, The pinching strength and pinching position cannot be adjusted. Therefore, depending on the type of film, the film may fall without being supported.

  The present invention has been made in view of the above circumstances, and is independent of the thickness of the film and the like, and can be fixed to any film and can be easily pulled out. An object of the present invention is to provide a shaw casten.

As shown in the figure, the present Schaukasten 1 includes a housing 10, an acrylic plate 12, a cover 14, an operation unit 16, a leg portion 17, and a light source 19 (not shown in FIG. 1). 3), and a film fixing portion 20 (not shown in FIG. 1, see FIG. 2, etc.) governed under the cover 14.

  The housing 10 includes a light source 19 for applying light to the acrylic plate 12 and a control unit that controls ON / OFF of the power source 19 in accordance with an operation from the operation unit 16, and the acrylic plate 12 is fitted therein. Has a window.

  The acrylic plate 12 uses, for example, a translucent acrylic resin as its material, and transmits the light of the light source 19 built in the housing 10 while diffusing it, thereby uniformly illuminating the film fixed on the surface thereof. The acrylic board 12 may also be called an opal board.

  The cover 14 is an openable / closable and removable cover for covering the film fixing unit 20. For example, when the clip position of the film fixing unit 20 is changed, or when the number of clips is changed, it is opened and closed as necessary. FIG. 2 shows the shaucus ten 1 with the cover 14 removed.

  The operation unit 16 includes a button for instructing ON / OFF of the light source 19 and a button for selecting an automatic mode or a manual mode. Here, the automatic mode is an operation mode in which the light source 19 is turned on simultaneously with the film fixing in the film fixing unit 20 and the light source 19 is turned off simultaneously with the removal of the film. The manual mode is an operation mode in which the user manually controls ON / OFF of the light source 19.

  The leg portion 17 is a fixture for stably installing or fixing the shaucus ten 1 on the desk.

  The light source 19 illuminates the acrylic plate 12 with a plurality of fluorescent lamps. The light source 19 and the acrylic plate 12 form a surface light source that uniformly illuminates the film fixed on the surface of the acrylic plate 12.

  As shown in FIG. 2, the film fixing unit 20 has a support bar 21 and a clip 22. The support bar 21 is fixed so as to extend along one side of the acrylic plate 12. The clip 22 has a leaf spring function, and by pressing against the acrylic plate 12 by its elasticity, various films such as an X-ray film and a general photographic film (the X-ray film 18 is illustrated in FIG. 1) can be pulled out. Fix in state.

  The structure of the support bar 21 and the clip 22 will be described in more detail with reference to FIGS. FIG. 3 is a view of the surface A of FIG. 2 as viewed from the B direction. 4 is an enlarged view of the film fixing unit 20 shown in FIG. FIG. 5 is a view of the clip 22 as viewed from the direction D of FIG. 6 is a view of the clip 22 as viewed from the B direction in FIG. 4 (or FIG. 5).

  As shown in FIGS. 3 and 4, the support bar 21 includes a first support part 210, a second support part 211, and a clip mounting part 212. The support bar 21 is fixed to the acrylic plate 12 by sandwiching one end of the acrylic plate 12 between the first support portion 210 and the second support portion 211. 3 and 4 exemplify the support bar 21 in which the second support portion 211 is shorter than the first support portion 210 by h in the C direction. This is because, for example, the acrylic plate 12 is fixed at an intermediate portion of the first support portion 210 by the end portion of the second support portion 211, thereby realizing stronger fixation. However, without being restricted to this, the acrylic plate 12 may be fixed at the intermediate portion of the second support portion 210 by the end portion of the first support portion 211, or the first support portion 210 and the first support portion 210 may be fixed to each other. A predetermined adhesive may be used in combination with the two support portions 211.

  The clip mounting part 212 has a size corresponding to the size of the clip 22 in the C direction. A plurality of clips 22 can be inserted into the clip mounting portion 212 as shown in FIG.

  The clip 22 includes a leaf spring portion 220 and a fixed button portion 221. The leaf spring portion 220 includes a first bent portion 220a in which one end of a leaf spring made of metal, resin, or the like is bent toward the first surface, and a second bent portion 220b in which the other end is bent in an S shape. The convex part 220c bent in a U-shape so as to form a convex shape on the second surface side between the first bent part 220a and the second bent part 220b, and one end of the fixed button part 221 are supported. A button support portion 220d for holding the button and a button hole for fitting the button of the clip 22. The clip 22 uses the elastic expansion and contraction of the convex part 220c to hook the first bent part 220a and the second bent part 220b on the clip mounting part 212, thereby the first bent part 220a and the second bent part 220b. The bent portion 220b can be attached to the support bar 21 while maintaining the shape of the bent portion 220b. The attached clip 22 can be moved (slid) along the longitudinal direction of the support bar 21, and at least one of the first bent portion 220 a and the second bent portion 220 b is removed from the support bar 21. It is also possible to remove.

  The fixing button portion 221 is made of a material (for example, resin) having a hardness that does not damage the film and a friction coefficient suitable for fixing the film, such as a resin, and is on the first bent portion 220a (the leaf spring portion 220). On the second surface side). The fixed button portion 221 includes a first inclined portion 221a, a second inclined portion 221b, a contact portion 221c, and a button portion 221d.

  The first inclined portion 221a has a slope that facilitates insertion of the film 18 when the fixed button portion 221 is attached to the support bar 21 (see FIG. 4) (for example, gentler than the second inclined portion 221b). (Slope). The first inclined portion 221a guides the movement of the film when the film is inserted between the film fixing portion 20 and the acrylic plate 12 (or when the film is pulled out from this position).

  The contact portion 221c is a portion that is located at the boundary between the first inclined portion 221a and the second inclined portion 221b and contacts the film. The contact portion 221c has a rounded shape so as not to damage the film.

  The button part 221 d is for fixing the fixed button part 221 to the leaf spring part 220. That is, the fixed button portion 221 is fixed to the leaf spring portion 220 by fitting the button portion 221d into the button hole of the leaf spring portion 220 and further supporting one end of the fixed button portion 221 by the button support portion 220d. In order to prevent the fixed button portion 221 from rotating with respect to the leaf spring portion 220, the button holes of the button portion 221d and the leaf spring portion 220 are preferably not oval but oval or rectangular.

  According to the shaw casten 1 according to the present embodiment described above, the following operations and effects can be realized.

  First, the film 18 is pressed and fixed to the acrylic plate 12 by inserting one end between the contact portion 221 c of the clip 22 and the acrylic plate 12 and the elasticity of the clip 22. At this time, since the first inclined portion 221a has a suitable angle, the fixed button portion 221 and the film can be inserted well without colliding without worrying about the insertion direction. The film 18 can be pulled out by applying a predetermined force downward, for example. At this time, since the first inclined portion 221a has a suitable angle, it is not necessary to strictly pull down downward, and information for releasing the pressing by the first bent portion 220a of the leaf spring portion 220 (for example, the front direction). It is also possible to pull out the film by applying a force to the film. Therefore, the user can realize good film fixing and film extraction without being influenced by the film insertion or extraction direction.

  Further, in the present Schaukasten, the number and position of the clips 22 can be arbitrarily changed. Therefore, for example, when a relatively heavy film is to be fixed, the number of clips 22 can be increased, or some (or all) clips 22 mounted on the support bar 21 can be moved to increase the number used. By doing so, the fixing strength of the film can be increased. On the contrary, when it is not necessary to fix the film firmly, or when it is desired to pull out the film with a small force, the fixing strength of the film can be weakened by removing or moving some clips 22. . Further, in the present shaucus ten 1, the film fixing strength can also be controlled by changing the bending angle of the first bent portion 220a. Therefore, the user can realize favorable film fixing and film drawing regardless of the type of film by freely controlling the film fixing strength. These actions and effects are also beneficial when, for example, the friction coefficient of the film surface is lowered or when the leaf spring portion 220 is elastically deteriorated due to long-term use.

  Also, in general, acrylic plates are not strictly flat. Therefore, for example, when the film is fixed with a stainless steel pin with a continuous contact surface as in the prior art, the fixing strength varies depending on the location due to the unevenness of the acrylic plate. However, since the film is fixed with dots at a plurality of positions using the plurality of clips 22 in the present shaukasten 1, the film can be fixed with a uniform strength, and good film fixing and film drawing can be realized. .

  In the present shaukasten 1, the film is fixed by a contact portion such as a resin having a rounded shape. Therefore, since the film surface is not damaged, the life of the film can be extended.

  The film fixture 20 included in the present shaucus ten 1 only needs to add a support bar 21 and a clip 22. Therefore, it can be realized easily and at low cost using an existing apparatus.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Specific examples of modifications are as follows.

  In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.

  As described above, according to the present invention, it is possible to realize a film fixture that can be fixed and easily pulled out regardless of the thickness of the film and the like, and a shaucus ten having the same. Can do.
