  Between the pair of support walls 9, 9, a support shaft 13 that supports the winding portion 12 </ b> B of the leaf spring member 12 in a rotatable manner is installed. The cover wall 10 includes a parallel wall 10A and an inclined wall 10B. The parallel wall 10A is a front edge portion in the vicinity of the front wall 3C. The parallel wall 10A is parallel to the bottom plate 3A. The inclined wall 10B is a rear edge portion away from the front wall 3C. The inclined wall 10B is inclined downward on the rear side. A slit-shaped opening 15 into which the leaf spring piece 12A can be inserted is formed between the rear end of the inclined wall 10B and the bottom plate 3A. The accommodating portion 14 is surrounded by the rounded portion 8 of the bottom plate 3 </ b> A, the pair of support walls 9, 9 and the cover wall 10, and the accommodating portion 14 of the leaf spring member 12 is configured on the wall bottom portion side of the case body 3.

  In the present embodiment, the leaf spring member 12 is pivotally supported by the support shaft 13 between the pair of support walls 9 and 9 so that the winding portion 12 </ b> B is rotatable around the circumference. The winding portion 12B is accommodated in the accommodating portion 14 of the case body 3 in a state where the leaf spring piece 12A drawn out from the winding portion 12B is pulled out from the opening 15 on the distal end side of the inclined wall 10B to the inside of the case body 3. Yes.

The guide member 5 is installed on the bottom plate 3A. As shown in FIG. 3B, the guide member 5 includes a slide plate 5A, a guide plate 5B, a rib piece 5C, and a pair of projecting pieces 5D and 5D.
The slide plate 5A slides in contact with the upper edges of the pair of rail portions 7,7. The slide plate 5A is slightly narrower than the bottom plate 3A. The guide plate 5B is erected on the upper surface side of the slide plate 5A and extends in the vertical direction. The guide plate 5B biases the rear end of the arranged articles 2 forward. The rib pieces 5C are integrally formed with the slide plate 5A and the guide plate 5B, and reinforce the bending rigidity of the plate-like guide plate 5B. The pair of projecting pieces 5D and 5D are erected on the bottom side of the slide plate 5A side by side in the width direction. These two protruding pieces 5D and 5D are inserted into the gap between the pair of rail portions 7 and 7. The protruding piece 5D has a claw shape, and a hook portion 5E is formed on the tip (lower end) side thereof. In a state where the protruding piece 5D is inserted through the gap between the pair of rail portions 7 and 7, the hook portion 5E protrudes to the back side of the bottom plate 3A of the case body 3 to prevent the protruding piece 5D from coming off. As a result, the guide member 5 is engaged with the rail portion 7. In addition, the guide member 5 slides along the rail portion 7 in a state where detachment from the rail portion 7 is restricted.

  The distal end portion 12 a of the leaf spring piece 12 </ b> A drawn out from the winding portion 12 </ b> B is attached to the bottom side of the guide member 5. The guide member 5 is urged toward the front wall 3 </ b> C of the case body 3 along the rail portion 7 by the elastic restoring force of the leaf spring piece 12 </ b> A.

  In the present embodiment, the partial length of the distal end side of the leaf spring piece 12 </ b> A also serves as the pulling body of the guide member 5. In other words, the traction body of the present embodiment is provided with the curl and rewinds itself by the elastic restoring force. However, as will be described later as the second embodiment, the traction body and the leaf spring piece may be separated from each other, and the traction body may be made of a flexible material that is soft and does not substantially have a spring property.

In the bottom plate 3A of the case body 3, in the rear end portion close to the back wall 3D, a through-hole 7A between the pair of rail portions 7 and 7 is omitted, so that a tongue-shaped stopper piece composed of a part of the bottom plate 3A. 16 is formed. When the guide member 5 retreats from the front to the rear, after the slide movement along the rail portion 7, the protruding piece 5D comes into contact with the stopper piece 16 and the retreat movement of the guide member 5 is restricted.
The guide member 5 is pulled by the leaf spring piece 12A and moves forward to the front wall 3C side. The forward movement of the guide member 5 is stopped when the guide plate 5B comes into contact with the front surface of the cover wall 10 or the back surface of the last article 2.

  As shown in FIG. 5, a window 20 is provided on the bottom center side of the front wall 3 </ b> C of the case body 3. In other words, the window portion 20 is formed on the wall on the side of the front surface or the back surface of the case body 3 to which the winding portion 12B is attached. That is, the window portion 20 may be provided on the front wall 3C of the case body 3 as in the present embodiment, or may be provided on the back wall 3D. The window portion 20 has a size that allows the winding portion 12 </ b> B accommodated inside the case main body 3 to be viewed.

  As an example, the window 20 is formed of a transparent resin material for the front wall 3C, and the surface on the bottom side of the front wall 3C is roughened by frosting or the like to be processed into an opaque state. It is formed by making it possible to transmit light only in the portion with transparent resin. In addition, the window part 20 may be formed by configuring the entire front wall 3C with an opaque member and opening a window hole at the bottom center side of the front wall 3C. Alternatively, the window portion 20 may be formed by making only the position corresponding to the window portion of the front wall 3 </ b> C made of transparent resin and making the other position with an opaque material. Moreover, it is good also as a structure which made it easy to visually recognize the surrounding surface of the winding part 12B from the exterior side by opening a window hole in 3 C of front walls, and arrange | positioning a lens member in the opening part.

  In the article display extrusion apparatus 1 of the present embodiment, the winding portion of the leaf spring piece 12A or the traction body (tip portion 12a) can be placed at an arbitrary position in the length direction of the leaf spring piece 12A or the traction body (tip portion 12a). A display portion 12C serving as a guide for the amount of feeding from 12B is formed. By visually recognizing the display unit 12 </ b> C through the window unit 20, the quantity of the articles 2 accommodated in the case body 3 can be grasped.

  The amount of extension of the leaf spring piece 12A can be grasped from the state of the leaf spring piece 12A or the pulling body through the window portion 20, for example, the size of the winding diameter created by the leaf spring piece 12A of the winding portion 12B. That is, by observing the leaf spring piece 12 </ b> A through the window portion 20, it is possible to grasp the remaining number of articles 2 accommodated in the case body 3.

Further, as shown in FIG. 8, the leaf spring member 12 of the present embodiment can draw out the leaf spring piece 12A from the winding portion 12B and extend it linearly for a predetermined length. The display unit 12 </ b> C of this embodiment is a number indicating the remaining quantity of the articles 2 accommodated in the case body 3.
The position and mode of the display portion 12C formed along the length direction of the leaf spring piece 12A are not particularly limited. As an example, when the guide member 5 is moved along the rail portion 7 to the position farthest from the front wall 3C, the display portion 12C on the outer peripheral surface of the winding portion 12B visible through the window portion 20 is guided. The number is shown as the maximum number of articles 2 that can be displayed and stored between the member 5 and the front wall 3C. Then, each time the guide member 5 is moved by extracting one article 2 stored between the guide member 5 and the front wall 3C, the numerical value of the display portion 12C decreases by one through the window portion 20. Print numbers like this. In other words, numbers are printed in the length direction of the leaf spring pieces 12A at intervals of the dimension (thickness dimension) of the article 2 in the front-rear direction. Specifically, a number indicating N is printed at a position where the feeding amount of the leaf spring piece 12 </ b> A corresponds to N pieces of the thickness dimension of the article 2. Accordingly, the display portion 12C formed on the leaf spring piece 12A or the pulling body (tip portion 12a) becomes a number indicating the remaining quantity of the articles 2 displayed in the case body 3.

  As shown in FIG. 8, in the state where the leaf spring piece 12A is fed out from the winding portion 12B and is stretched linearly for a predetermined length, the display portion 12C is provided at a predetermined position on the outer peripheral surface of the winding portion 12B. Either one is formed upright. That is, any one of the plurality of display portions 12C formed on the surface of the leaf spring piece 12A through the window portion 20 of the front wall 3C in a state where the leaf spring piece 12A is pulled out from the leaf spring member 12 by a required length. Visible in a standing display state.

On the other hand, in the bottom plate 3A of the case main body 3, a plurality of slit-like plural (four in the example of FIG. 2) fitting holes 21 along the length direction of the bottom plate 3A are provided in a portion near the side wall 3B, for a total of eight. It is formed one by one. A plate-like spacer 22 shown in FIG. The spacer 22 has a partition plate 22A slightly shorter than the bottom plate 3A and slightly shorter than the side wall 3B, and a plurality of (four in the example of FIG. 4) protrusions formed on the bottom of the partition plate 22A. It is comprised from the piece 22B. By fitting the fitting piece 22B into the fitting hole 21, the spacer 22 is erected on the inner side of the side wall 3B as shown in FIG. 6 or FIG.
The spacer 22 having the above structure is used when the article 2 having a width smaller than the distance between the pair of side walls 3B, 3B of the case body 3 is displayed on the case body 3. By appropriately changing the fitting position of the spacer 22 with respect to the fitting hole 21 as shown in FIG. 6 or FIG. 7, it is possible to cope with the display arrangement of the articles 2 having different widths.

In the article display extrusion apparatus 1 having the above structure, the guide member 5 is slid along the rail portion 7 to the innermost side of the case body 3, and a gap formed between the front wall 3 </ b> C and the guide member 5. A necessary number of articles 2 are arranged and used.
When one front row of articles 2 accommodated in the case body 3 is taken out, the guide member 5 is pulled forward by the leaf spring piece 12A of the leaf spring member 12, so that the remaining rows of articles 2 are guided by the guide member. 5 is pushed out until it abuts against the front wall 3C. Thereby, even if one article 2 in the forefront row of the case main body 3 is taken out, the other articles 2 arranged in the display can be advanced without being brought down inside the case main body 3.

In the state where the guide member 5 is slid along the rail portion 7 to the rear of the case body 3 and a predetermined number of articles 2 are arranged in the gap formed between the front wall 3C and the guide member 5, The number as the display unit 12 </ b> C printed on the leaf spring piece 12 </ b> A can be read from the window unit 20. At this time, the number visually recognized from the window portion 20 corresponds to the total number of articles 2 displayed.
Next, when one article 2 in the front row of the case body 3 is taken out, the number that can be read from the window portion 20 of the front wall 3C is reduced by 1, and the total number of articles 2 remaining in the case body 3 can be grasped. Each time the article 2 is taken out from the case body 3, the numerical value that can be read from the window portion 20 decreases. Thereby, it is possible to recognize a state in which the remaining quantity of the articles 2 in the case main body 3 is reduced by approaching this numerical value. Therefore, the article 2 may be replenished at a necessary time according to the numerical value visually recognized from the window portion 20.

According to the article display extrusion apparatus 1 having the above structure, the remaining number of articles 2 can be grasped by looking into the display section 12C inside the window section 20 of the front wall 3C. For this reason, for example, even if the article 2 is relatively light and small like a cigarette box, the state of the remaining quantity of the article 2 in the case body 3 can be easily and accurately grasped.
When the article 2 is a cigarette box or the like, a plurality of case bodies 3 having the above-described structure are prepared in accordance with the type and number of cigarettes, and a plurality of these are placed in a fixture body (not shown). It is good to display. Thus, even if the case bodies 3 are arranged close to each other so that the number of articles 2 inside the case body 3 cannot be directly visually confirmed, each case body 3 can be viewed by looking through the window 20 of each case body 3. The remaining quantity of the articles 2 inside the main body 3 can be easily grasped.

  In the present embodiment, the display unit 12 </ b> C in an aspect in which the remaining quantity of the article 2 can always be confirmed through the window part 20 regardless of the remaining quantity of the article 2 is illustrated. However, the present invention is not limited to this. You may make it visible with the window part 20 only that it reached the predetermined remaining quantity (for example, 5 pieces) or less. Specifically, when the guide member 5 reaches a position corresponding to a predetermined remaining quantity, the color or pattern of the leaf spring piece 12 </ b> A viewed through the window portion 20 may be changed.

  The winding part 12B of this embodiment has a double winding structure of a leaf spring piece 12A and a display piece (tape piece 12D). A display portion 12C serving as a guide for the amount of extension from the winding portion 12B of the leaf spring piece 12A is formed on the display piece (tape piece 12D).

  FIG. 9 is a perspective view showing a leaf spring member according to a modification of the first embodiment. The leaf spring member of this modification has a double winding structure of a leaf spring piece 12A and a tape piece (display piece) 12D. The display unit of this modification is a color display unit 12E printed on the tape piece 12D. That is, instead of the display portion 12C of the first embodiment being a number, in this modification, the color display portion 12E that is color-coded is intermittently formed on the tape piece 12D. Even when the leaf spring piece 12A is a material such as spring steel and it is difficult to print on the surface, the color display portion can be obtained by winding the tape piece 12D made of an oleophilic resin and the leaf spring piece 12A twice. 12E can be formed easily.

  For example, as an example of the color display unit 12E, the color display unit 12E at a position visually recognized through the window unit 20 when the number of articles 2 accommodated in the case body 3 is large is set as the first color. . When the number of articles 2 accommodated in the case body 3 is reduced, for example, when the number of articles 2 is 5 or less, 3 or less, the color display unit 12E at a position visually recognized through the window unit 20 is displayed. The second color is different from the first color. Thus, the remaining quantity of the article 2 can be grasped based on the color of the color display part 12E by changing the color display part 12E according to the remaining quantity of the article 2 through the window part 20. The first color and the second color are different in at least one of lightness, saturation, and hue. That is, the display part of the present modification formed on the leaf spring piece 12 </ b> A or the pulling body is a color display part 12 </ b> E indicating the remaining quantity of the articles 2 displayed in the case body 3. As an example, when the guide member 5 is moved along the rail portion 7 to the position farthest from the front wall 3C (that is, when the guide member 5 is slid to the innermost side of the case body 3), the window Light blue is printed as the color display portion 12E on the outer peripheral surface of the winding portion 12B that can be visually recognized through the portion 20. Further, the article 2 stored between the guide member 5 and the front wall 3C is extracted, and the color indicated by the color display portion 12E is printed as the same light blue through the window portion 20 every time the guide member 5 moves. Keep it. Further, when the number of articles 2 displayed and stored between the guide member 5 and the front wall 3C is reduced to five or three, the dark blue color display portion 12E can be visually recognized from the window portion 20. It is good to print like this. Thereby, the remaining quantity of the articles | goods 2 can be grasped | ascertained by visually observing the color of the color display part 12E which faces the window part 20. FIG. The color display of the color display unit 12E is not limited to this example. When the remaining quantity of the article 2 is large, the color is blue, when the remaining quantity of the article 2 is small, yellow, and the remaining quantity of the article 2 is 5 or 3 The color display portion 12E may be provided so that the color becomes red when the number is reduced.

  As described above, the example of the display portion formed on the leaf spring piece 12A or the tape piece 12D that is double-wrapped with the leaf spring piece 12A is not limited to numeric printing or color display portion printing, but may include other pictures, characters, symbols, and the like. It may be a pattern. That is, the display unit may be a color display unit 12E that indicates the remaining quantity of the articles 2 accommodated in the case body 3 by color, or a pattern display unit (not shown) that indicates the remaining quantity by a pattern.

  Further, the display unit may be realized as a change in the width dimension of the leaf spring piece 12A. That is, the width dimension of the leaf spring piece 12 </ b> A visually recognized through the window portion 20 may be changed according to the amount of extension of the leaf spring piece 12 </ b> A. Thus, the specific form of the display unit is not limited as long as the display form can grasp the replenishment timing of the article 2 when the remaining number of the articles 2 accommodated in the case body 3 decreases. .

  In addition to the above, in a range where the number of articles 2 is sufficiently remaining, a color display portion with a light hue is provided, and as the remaining amount of the article 2 decreases, a color display portion with a darker hue or another color is obtained. A color display portion with such a gradation may be provided. In this case, the color display portion may be colored on the entire surface of the tape piece 12D, or may be a color display portion by tape application, and only the range visible from the window portion 20 may be the color display portion.

  Further, in a range where the number of the articles 2 remains sufficiently, the metal color of the base of the leaf spring piece 12A is visually observed from the window section 20, and when the remaining quantity of the articles 2 becomes a predetermined number or less, the window section 20 has a predetermined color. You may comprise so that the color display part and pattern display part of this color may be displayed. Such a display part is implement | achieved by forming a color or a pattern continuously in the length area | region of a part of leaf | plate spring piece 12A or a tow | pulling body. Specifically, the tape-shaped display piece on which the display unit is formed may be attached to the surface of the leaf spring piece 12A facing the window unit 20. Then, when the leaf spring piece 12A or the pulling body reaches a predetermined feeding amount, the end of this length region is visually recognized through the window portion 20, so that the remaining quantity of the article 2 reaches a predetermined number. It is grasped that.

  Instead of the first embodiment and its modification, a traction body such as a flexible resin tape that is not a leaf spring piece may be provided on the distal end side of the leaf spring piece 12A. And it can also be set as the structure which attaches the front-end | tip of a pulling body to the guide member 5, and pulls.

FIG. 10 is a front view showing a window portion 20 according to another modification of the first embodiment. The window part 20 of this modification is a means for visually grasping the magnitude of the winding diameter of the winding part 12B. That is, the display unit of the present modification is not a display form such as a number or a color display unit, but is based on recognizing the size (position of the outer peripheral surface) of the winding unit 12B itself, the article 2 in the case body 3. It is to grasp the number of.
In the structure of this modification, a reference line 25 is printed on the transparent window 20 of the front wall 3C. When the number of articles 2 in the case main body 3 has decreased, the leaf spring piece 12A is wound around the winding portion 12B so that the outer diameter of the winding portion 12B increases, resulting in exceeding the reference line 25 of the window portion 20. Thus, the winding part 12B becomes larger. When the winding part 12B becomes larger than the reference line 25, it can be recognized that the number of articles 2 in the case body 3 has decreased to reach a predetermined number.

A structure in which the number of articles 2 in the case body 3 can be recognized by the size of the outer diameter of the winding part 12B without providing a display part in the leaf spring member 12 as in this modification may be adopted. .
In the case of this embodiment, the front wall 3C is subjected to printing, sticking, or the like so that the front wall 3C cannot be seen through, and only the portion of the window portion 20 is allowed to pass through, and the reference line 25 is formed in that portion. It is good to leave. Thereby, since only the outer peripheral surface of winding part 12B can be seen through window part 20, it is easy to recognize the winding diameter of winding part 12B.

<Second embodiment>
FIG. 11 is a side sectional view schematically showing the structure of the second embodiment of the article display extrusion apparatus of the present invention. The article display extrusion device 30 of this embodiment is provided with a plate spring member 12 having the same structure as described above on the front wall 3C side of the case body 3 and a plate spring on the bottom plate 3A on the back wall 3D side of the case body 3. The structure is such that another leaf spring member 32 having the same structure as the member 12 is provided. The leaf spring member 12 biases the guide member 5 forward, and the leaf spring member 32 biases the guide member 5 backward. However, the elastic force of the leaf spring member 32 is smaller than that of the leaf spring member 12. For this reason, the biasing force acting on the guide member 5 is mainly the biasing force of the leaf spring member 12. The combined biasing force of the leaf spring member 32 and the leaf spring member 12 drives the guide member 5 forward. The basic configuration of the leaf spring member 32 is the same as that of the leaf spring member 12, and is constituted by a leaf spring piece 32A and a winding portion 32B. A number or the like is intermittently provided at a predetermined position in the length direction of the leaf spring piece 32A. Color display portions such as a display portion and a coloring portion are formed.

The distal end of the leaf spring piece 32A is attached to the bottom side of the guide member 5, and the leaf spring piece of the leaf spring member 32 in cooperation with the leaf spring piece 12A of the leaf spring member 12 according to the sliding movement of the guide member 5. 32A expands and contracts.
In this embodiment, a window portion is provided on the back wall 3D side of the case body 3, and the display portion of the leaf spring piece 32A can be visually recognized from the back side of the case body 3 through the window portion. From the back side, the remaining quantity and remaining amount of the articles 2 in the case body can be grasped.
In addition, in the article display extrusion apparatus 30, display parts such as numbers and color-coded parts are intermittently provided on both the leaf spring member 12 disposed on the front wall 3C side and the leaf spring member 32 disposed on the back wall 3D side. Of course, the remaining quantity of the article 2 can be grasped from both the front side and the back side of the case body 3.

  The article display extrusion apparatus 30 of this embodiment can grasp the remaining quantity of the articles 2 in the case body from the back side. Thereby, for example, it is advantageous when grasping the remaining quantity of articles from the back side and replenishing articles 2 from the front side. Alternatively, it is possible to provide an advantageous structure in the case where the remaining quantity of articles is grasped from the back side and the article 2 is replenished from the back side of the case body 3. In addition, as described above, a structure that can grasp the remaining quantity of the article 2 from both before and after the case body 3 can be provided.

In the present invention, the attachment position of the leaf spring member 12 is not limited to the front wall side, the front wall side, and the back wall side of the case body 3.
In the first and second embodiments, the leaf spring member 12 is provided on the front wall 3 </ b> C side of the case body 3, but instead of this, the accommodating portion 14 may be formed only on the back wall 3 </ b> D side of the case body 3. . The leaf spring member 12 is accommodated only on the back wall 3D side, and a pulley or the like is provided on the front wall 3C side of the case body 3 so that the extending direction of the leaf spring piece 12A faces the guide member 5 side via the pulley. You may change backwards. Thereby, even if the accommodation position of the leaf | plate spring member 12 is set only to the back wall 3D side, the structure which pulls the guide member 5 to the front wall 3C side of the case main body 3 is realizable.

In that case, the length of the leaf spring member 12 is required to be about twice that of the first embodiment, but it is not necessary to make the entire length a leaf spring member, and about half of that, that is, about the length of the case body 3, It is also possible to substitute a tape having no spring property. That is, the leaf spring piece 12A is arranged in the portion constituting the winding portion 12B, the tape is connected to the tip end side of the leaf spring piece 12A, and the portion on the side connected to the guide member 5 via the pulley is substituted with the tape. It can be a structure. And it can comprise so that the leaf | plate spring piece 12A may move only the distance (distance equivalent to the length of the rail part 7) to which the guide member 5 moves. In this case, the plate spring member 12 having the same length as that of the structure of the first embodiment is used, and a tape having the same length as that of the plate spring member is extended to the front end side of the plate spring piece 12A. When the tape is connected to the guide member 5 side via a pulley, the guide member 5 can be pulled.
In the case of this structure, since the leaf spring member 12 is accommodated on the back wall 3D side of the case body 3, a window 20 is provided on the back wall 3D side of the case body 3 so that the rest of the article 2 is left from the rear side of the case body 3. The quantity can be grasped.

<Third embodiment>
12 to 16 show a third embodiment of the article display extrusion apparatus according to the present invention. The article display extruding device 50 of the third embodiment has a case body 3 having the same structure as the case body 3 applied to the first embodiment. The present embodiment is characterized in that the leaf spring member 52 accommodated in the case body 3 has a structure different from the leaf spring member 12 of the first embodiment. Other structures are the same as those of the first embodiment. Therefore, in the description of the present embodiment, the description of the parts equivalent to the structure of the first embodiment described above will be omitted, and the description will focus on the differences.

In the structure of the third embodiment, the leaf spring mechanism 62 includes a cylindrical case 56, a support shaft 57, an extension portion 58, and a traction body 59.
The cylindrical case 56 accommodates a spiral leaf spring piece 53 and locks the outer peripheral end of the leaf spring piece 53. The support shaft 57 is connected to the center end of the spiral leaf spring piece 53, passes through a part of the cylindrical case 56, and extends to the outside of the cylindrical case 56. The extension portion 58 is formed to extend from a part of the cylindrical case 56. The traction body 59 is wound around the outer peripheral portion of the extension portion 58 and can be fed out. A part of the support shaft 57 is pivotally supported by a part of the case body 3, and the pulling body 59 can be unwound from the outer peripheral portion of the extension portion 58 and can be wound by the elastic restoring force of the leaf spring piece 53.

More specifically, as shown in FIGS. 12 and 13, the leaf spring member 52 is mainly composed of a winding portion 55, a cylindrical case 56, a support shaft 57, an extension portion 58, and a pulling body 59.
The winding part 55 includes a leaf spring piece 53 wound spirally. The cylindrical case 56 accommodates the winding part 55. The support shaft 57 is disposed so as to penetrate the center portion of the cylindrical case 56. The extension portion 58 is formed to extend from the central portion of the side wall portion 56 b provided on one side of the peripheral wall 56 a of the cylindrical case 56. The traction body 59 is attached and wound around the outer peripheral side of the extension portion 58 so as to be freely drawn out, and has a belt shape. Specifically, the starting end portion of the tape-shaped pulling body 59 is adhered and fixed to a part of the peripheral surface of the extension portion 58, or a slit is formed in a part of the extension portion 58, and the pulling is performed on the slit. The body 59 is blocked. Then, the tow body 59 is wound around the extension portion 58 so that the tow body 59 is wound around the extension portion 58 so as to be freely extended. A terminal end portion 59 </ b> A (see FIG. 14B) of the pulling body 59 is connected to the slide plate 5 </ b> A of the guide member 5. When the traction body 59 is wound around the extension portion 58 by the elastic restoring force of the leaf spring member 52, the end portion 59A of the traction body 59 pulls the slide plate 5A of the guide member 5 forward.
The outer diameter of the cylindrical extension 58 is formed smaller than the outer diameter of the cylindrical case 56. As a result, when the traction body 59 is entirely wound around the peripheral surface of the extension portion 58 to be in a wound state, the outermost peripheral portion of the traction body 59 is flush with the peripheral surface position of the cylindrical case 56 or the cylindrical case 56. Located inside the peripheral surface. The traction body 59 is made of a thin tape made of resin or metal. As an example, a glass fiber reinforced composite material obtained by blending glass fibers with a resin or a cloth knitted with reinforcing fibers can be used. The pulling body 59 made of these fibers is good because it is difficult to cut and stretch. Further, in the case of a tape-like traction body 59 made of glass fiber or woven glass fiber, the surface of the traction body 59 may be coated or impregnated with a vinyl chloride resin before printing the display portion. By printing, it is possible to suitably form a color display portion or a pattern display portion such as a character or a picture that is easily visible.

An inner peripheral end of a leaf spring piece 53 constituting the winding portion 55 is attached to the distal end side (left side in FIG. 13) of the support shaft 57 arranged so as to penetrate the center portion of the winding portion 55. ing. The outer peripheral end of the leaf spring piece 53 is fixed to a part of the peripheral wall of the cylindrical case 56. In addition, a disc-shaped flange plate 60 is integrated with the other end of the support shaft 57 inserted through the cylindrical case 56 and the extension 58 and extending to the outside of the extension 58. On the outer surface of the flange plate 60, a rib-like protrusion 61 is formed so as to protrude.
Further, the leaf spring member 52 is supported in a state where the protrusion 61 is inserted into a slot (not shown) formed in the support wall 9 (see FIG. 2) of the case body 3 and the flange plate 60 is stopped. Thus, the leaf spring member 52 is accommodated in the accommodating portion 14 between the pair of support walls 9 of the case body 3. Further, the belt-like traction member 59 is drawn out from the cylindrical extension 58 and pulled out from the opening 15 on the tip side of the inclined wall 10B to the inside of the case body 3. Then, the leading end portion of the pulled pulling body 59 is fixed to the bottom side of the guide member 5.

The leaf spring mechanism 62 of the present embodiment is the same as the first embodiment in that a biasing force can be applied to the guide member 5 when the guide member 5 is slid along the rail portion 7 of the case body 3. .
When the guide member 5 is slid along the rail portion 7 inside the case body 3, the user manually moves the guide member 5 so as to move away from the front wall 3 </ b> C of the case body 3. As a result, the tow body 59 is fed out from the extension portion 58 by a required length. Accordingly, the cylindrical case 56 is rotated, and the leaf spring piece 53 constituting the winding portion 55 is elastically deformed. Due to the elastic restoring force of the leaf spring piece 53, a biasing force acts on the guide member 5 so as to be pulled back to the front wall 3 </ b> C side via the pulling body 59. Therefore, when the user releases his / her hand from the guide member 5, the guide member 5 biases the article 2 toward the front wall 3 </ b> C (front) on the inner side of the case body 3. Therefore, the guide member 5 can restrain the article 2 and, when the article 2 is taken out from the front end side of the case body 3, the remaining article 2 can be put out.

  Also in the present embodiment, it is possible to read and grasp the number printed on the pulling body 59, that is, the remaining quantity of the displayed article 2 through the window portion 20 of the front wall 3C. Similar to the structure of the first embodiment, when one article 2 in the front row of the case body 3 is taken out, the number that can be read from the window portion 20 of the front wall 3C is reduced by 1, and the number of articles 2 remaining in the case body 3 can be grasped. . Each time the article 2 is taken out from the case main body 3, the numerical value that can be read through the window portion 20 decreases. Therefore, when this numerical value approaches 0, it is possible to recognize a state in which the inventory in the case main body 3 decreases. The article 2 may be replenished at a necessary time according to the previous numerical value. In the structure of the present embodiment, the same effects as those of the first embodiment can be obtained with respect to the effects of this point.

<Fourth embodiment>
17 to 21 show a fourth embodiment of the article display extrusion apparatus according to the present invention. The article display extrusion apparatus 70 of the fourth embodiment has a case body 3 having the same structure as the case body 3 applied to the first embodiment. The fourth embodiment is characterized in that the leaf spring member 72 accommodated in the case body 3 has a structure different from that of the leaf spring member 12 of the first embodiment. Other structures are the same as those of the first embodiment. Therefore, in the description of the present embodiment, the description of the parts equivalent to the structure of the first embodiment described above will be omitted, and the description will focus on the differences.

In the structure of the fourth embodiment, the leaf spring mechanism 82 includes a cylindrical case 76, a support shaft 77, and a puller 79.
The cylindrical case 76 accommodates a spiral leaf spring piece 73 and locks the outer peripheral end of the leaf spring piece 73. The support shaft 77 is connected to the center end of the spiral leaf spring piece 73 and extends through the cylindrical case 76 to the outside of the cylindrical case 76. The traction body 79 is wound around the outer peripheral portion of the cylindrical case 76 so as to be freely drawn out. A part of the support shaft 77 is pivotally supported by a part of the case body 3, and the pulling body 79 can be unwound from the outer periphery of the cylindrical case 76 and can be wound up by the elastic restoring force of the leaf spring piece 73. It becomes.

More specifically, as shown in FIGS. 17 to 19, the leaf spring member 72 is mainly composed of a winding portion 75, a cylindrical case 76, a support shaft 77, and a pulling body 79.
The winding part 75 includes a leaf spring piece 73 wound spirally. The cylindrical case 76 accommodates this winding part 75. The support shaft 77 is disposed so as to penetrate the center portion of the cylindrical case 76. The tow body 79 is attached and wound around the outer peripheral portion of the peripheral wall portion 76a of the cylindrical case 76 so as to be freely drawn out, and has a belt shape. Specifically, the starting end of the tape-shaped pulling body 79 is bonded and fixed to a part of the peripheral surface of the cylindrical case 76, or a slit is formed in a part of the cylindrical case 76 to pull the pulling body 79. Is blocked through the slit. The traction body 79 is wound around the cylindrical case 76 so that the traction body 79 can be unwound around the cylindrical case 76.

An inner peripheral end of a leaf spring piece 73 constituting the winding portion 75 is fixed to the tip end side of the support shaft 77 disposed so as to penetrate the center portion of the winding portion 75. The outer peripheral end of the leaf spring piece 73 is fixed to a part of the inner peripheral surface of the cylindrical case 76. In addition, a disc-shaped flange plate 80 is integrated with the other end portion of the support shaft 77 extending through the peripheral wall portion 76a of the cylindrical case 76 to the outside thereof. A rib-like protrusion 81 is formed to protrude from the center of the outer surface of the flange plate 80.
Further, the leaf spring member 72 is supported in a state where the protrusion 81 is inserted into a slot (not shown) formed in the support wall 9 (see FIG. 2) of the case body 3 and the flange plate 80 is prevented from rotating. Thus, the leaf spring member 72 is accommodated in the accommodating portion 14 between the pair of support walls 9 of the case body 3. The belt-shaped pulling body 79 is drawn out from the outer peripheral portion of the cylindrical case 76 and pulled out from the opening 15 on the distal end side of the inclined wall 10B to the inside of the case body 3. The leading end of the drawn puller 79 is attached to the bottom side of the guide member 5.

The article display extrusion device 70 of the present embodiment is the same as the structure of the first embodiment in that the guide member 5 can be slid along the rail portion 7 of the case body 3.
When the guide member 5 is slid along the rail portion 7 inside the case body 3, the user manually moves the guide member 5 so as to move away from the front wall 3 </ b> C of the case body 3. As a result, the traction body 79 is pulled out from the cylindrical case 76 by a required length. Along with this, the cylindrical case 76 also rotates, and the leaf spring piece 73 constituting the winding part 75 is elastically deformed. For this reason, an urging force is applied to the guide member 5 by the elastic restoring force of the leaf spring piece 73 so as to be pulled back to the front wall 3 </ b> C side via the pulling body 79. Therefore, when the user releases his / her hand from the guide member 5, the guide member 5 urges the article 2 toward the front wall 3 </ b> C side inside the case body 3. Therefore, the guide member 5 can restrain the article 2 and, when the article 2 is taken out from the front end side of the case body 3, the remaining article 2 can be put out.

According to the article display extrusion apparatus according to the above-described embodiment, the remaining amount of the article in the case body is reliably ensured by observing the display unit provided at an arbitrary position in the length direction of the leaf spring piece through the window part. I can grasp it. Therefore, by visually recognizing the display part through the window part, it is possible to grasp the article replenishment time for the case body, and it is possible to reliably replenish the article.
If the display unit is represented by numbers, the remaining number of articles can be easily and accurately grasped by numbers. In addition, if the display unit is a color display unit or a pattern display unit and the display unit has a color that changes according to the quantity of articles in the case body, the color or pattern of the display unit is recognized through the window unit. By doing so, the remaining quantity of articles can be grasped.
When it is difficult to directly print the display portion of the leaf spring piece of the leaf spring member, the winding portion of the leaf spring member may have a double winding structure of the leaf spring piece and the display piece. Thereby, it is possible to reliably form an easily recognizable display portion such as printing numbers, colors or patterns on the display piece.

<Fifth embodiment>
22 to 24 show a fifth embodiment of the article display extrusion apparatus according to the present invention. FIG. 22 is a plan view of the article display extrusion apparatus 90 of this embodiment. 23A is a cross-sectional view taken along line AA in FIG. FIG. 23B is an enlarged view of the vicinity of the rail portion 7 in FIG. 23A. FIG. 24A is a side view of the guide member 5 of the present embodiment. 24B is a cross-sectional view taken along line BB in FIG. 23A.
In FIG. 22, the state in which the guide member 5 is pulled out to the rearmost side close to the back wall 3D is illustrated by a solid line, the state in which the guide member 5 is positioned in the foremost side close to the front wall 3C, and the middle part in the front-rear direction A state in which the guide member 5 is located is shown by a broken line.

  As shown in FIGS. 24A and 24B, the guide member 5 includes a slide plate 5A, a guide plate 5B, a rib piece 5C, a protruding piece 5D, and a hook portion 5E. The slide plate 5A contacts the upper edge of the rail portion 7 and slides in the pushing direction. The guide plate 5B is a plate-like member that urges the rear surface of the last article 2. The rib pieces 5C are reinforcing portions that reinforce the bending rigidity of the guide plate 5B. The protruding piece 5D protrudes below the slide plate 5A. The protruding piece 5 </ b> D is a portion that is inserted into the gap between the pair of rail portions 7 and 7 and engages with the rail portion 7. The hook portion 5E is a claw portion that rises outward from the protruding piece 5D and engages with the inner edge 701 of the rail portion 7.

  The case body 3 of the present embodiment includes a pair of rail portions 7 and 7 that are parallel to each other, as in the first embodiment. The guide member 5 includes clamping portions 5 </ b> L that sandwich the rail portion 7 from the vertical direction and slide in the extrusion direction on both sides of the width of the guide member 5. The clamping part 5L slides in the pushing direction with respect to the rail part 7.

In addition to this, the guide member 5 includes an upright piece 5F continuously formed at the lower portion of the guide plate 5B, a reinforcing rib 5G that reinforces the bending rigidity of the upright piece 5F, and a top cover that is vertically opposed across the holding portion 5L. A moving wall 5M and a lower sliding wall 5N are provided.
As shown in FIG. 24B, the guide member 5 includes a latching portion 5H that latches the tip of the leaf spring piece 12A and receives a biasing force from the leaf spring piece 12A. A circular hole (not shown) is formed at the tip of the leaf spring piece 12A, and the latching portion 5H is inserted into this circular hole. A return portion 5P that protrudes rearward is formed on the load of the hook portion 5H. Since the leaf spring piece 12A is always urged forward by the elastic restoring force, the leaf spring piece 12A is prevented from falling off by the return portion 5P protruding to the opposite side.

  Further, a tape pressing portion 5K is provided in front of the latching portion 5H and a position slightly higher than the latching portion 5H. The tape pressing portion 5K of the present embodiment constitutes the lower edge of the opening 5J provided in the standing piece 5F. The tip of the leaf spring piece 12A is inserted through the opening 5J. The distal end portion of the leaf spring piece 12A inserted through the opening 5J is hooked on the hook portion 5H.

  A display piece (tape piece 12D) is attached from the base end side of the leaf spring piece 12A to the vicinity of the tip. The tape piece 12D is attached to the surface (the lower surface in FIG. 24B) on the side facing the window portion 20 of the plate spring piece 12A. The tape pressing portion 5K presses the end portion 12F on the front end side of the display piece (tape piece 12D) against the leaf spring piece 12A. Since the tip of the leaf spring piece 12A is hooked on the hook portion 5H, the end portion 12F of the tape piece 12D is constantly pressed against the leaf spring piece 12A by the tape pressing portion 5K. This prevents the tape piece 12D from peeling off from the leaf spring piece 12A.

  As shown in FIGS. 23A and 23B, the upright piece 5F of the guide member 5 is fitted in a gap between a pair of guide strips 702 parallel to each other. Thus, the guide member 5 slides along the rail portion 7 while maintaining the standing posture shown in FIG. 23A. The guide strip 702 constitutes the rail portion 7 together with an upper projection 703 and a lower projection 704 described later.

At least one of the upper surface or the lower surface of the rail portion 7 is formed with a ridge portion extending along the extrusion direction. In the present embodiment, protrusions (upper protrusions 703 and lower protrusions 704) are formed on both the upper surface and the lower surface of the rail portion 7. That is, the protrusion part of this embodiment contains the upper protrusion 703 formed in the upper surface of a rail part, and the lower protrusion 704 formed in the lower surface of a rail part.
And the top part of the protruding part (upper protruding line 703, lower protruding line 704) and the clamping part 5L are in point contact in the cross section (FIGS. 23A and 23B) orthogonal to the extrusion direction. Specifically, the upper protrusion 703 and the lower protrusion 704 have a semicircular cross-sectional shape. The top of the upper ridge 703 contacts the lower surface of the upper sliding wall 5M, and the top of the lower ridge 704 contacts the upper surface of the lower sliding wall 5N. Thus, in this embodiment, the protrusion is provided on the rail portion 7 in the case body 3 instead of the guide member 5. Thereby, the contact area of the guide member 5 and the rail part 7 becomes small, and while making the slidability of the guide member 5 favorable, the abrasion resistance of a protrusion part is fully ensured. This is because, by providing the protrusion on the rail portion 7 of the case body 3, the protrusion is formed to be sufficiently longer than the longitudinal dimension of the guide member 5 over substantially the entire length of the case body 3 in the front-rear direction. Because it can.

  The top of the upper protrusion 703 and the top of the lower protrusion 704 are formed at different positions in the width direction in the cross section. Thereby, even when an external force in a lateral direction is applied to the guide member 5, the top of the upper protrusion 703 and the top of the lower protrusion 704 support the guide member 5 at different positions in the width direction. The member 5 is suitably prevented from lying down toward the side wall 3B.

  In the cross section, the curvature radii of the upper protrusion 703 and the lower protrusion 704 are different from each other. Of the upper ridge 703 or the lower ridge 704, the top of one (upper ridge 703) having a larger radius of curvature is outward in the width direction in the cross section than the top of the other (lower ridge 704). Is located. Here, the protrusion (lower protrusion 704) having a small radius of curvature is more worn by friction with the guide member 5 than the protrusion (upper protrusion 703) having a large radius. Therefore, when the guide member 5 is repeatedly moved forward or backward, the upper protrusion 703 is more excellent in wear resistance than the lower protrusion 704. In this embodiment, the protrusion (upper protrusion 703) having excellent wear resistance is arranged on the outer side in the width direction, so that even if the lower protrusion 704 is worn, It is possible to support the guide member 5 stably. In other words, the article display extrusion apparatus 90 of this embodiment has a structure with excellent durability.

An insertion piece 3E extending in the front-rear direction is formed on the lower surface of the bottom plate 3A of the case body 3. The insertion piece 3E protrudes downward from the lower surface of the bottom plate 3A. The lower end of the insertion piece 3E is located below the lower end of the side wall 3B. On the other hand, the shelf (not shown) of the fixture body on which the case body 3 of the present embodiment is installed has a slit formed at a position corresponding to the insertion piece 3E. When the case body 3 is placed on the shelf board, the case body 3 can be locked to the shelf board by inserting the insertion piece 3E from above into the slit. When the case body 3 is thus placed on the shelf board, the side wall 3B of the case body 3 is grounded to the upper surface of the shelf board.
