  Hereinafter, embodiments of the present invention will be described in detail. In addition, the same number is attached | subjected to the structure part which has the same function, and duplication description is abbreviate | omitted.

  Hereinafter, the music stand according to the first embodiment of the present invention will be described with reference to FIG. FIG. 2 is a diagram showing a schematic configuration of the music rest 4 of the present embodiment. As shown in FIG. 2, the music stand 4 includes two slits 410 </ b> L and 410 </ b> R that respectively accommodate two corners at the lower left and right ends of the musical score 8 in a booklet form and in an open state. The two slits 410 </ b> L and 410 </ b> R are provided in the back surface portion 41 that supports the musical score 8. The back surface portion 41 can be a rectangular plate, for example, but the shape may be any shape as long as the back of a musical score, a cover, etc. can be leaned over.

  The distance between the two slits 410L and 410R is preferably shortened as it goes to the lower end side of the back surface portion 41. For example, the left end of the slit 410L, which is a slit on the left side from the center of the back surface portion 41, is positioned on the upper end side of the back surface portion 41 with respect to the right end of the slit 410L, and the slit 410R, which is a slit on the right side of the center of the back surface portion 41. It is desirable that the right end is located on the upper end side of the back surface portion 41 rather than the left end of the slit 410R. If the preferred arrangement of the two slits 410L and 410R is simply expressed, it is desirable that the two slits 410L and 410R are arranged in a V shape (reverse C shape) on the back surface portion 41.

  As described above, by providing the two slits 410L and 410R on the back surface portion 41, the left and right corners of the musical score 8 can be accommodated in the two slits 410L and 410R, respectively, so that the musical score is held well. It is possible to prevent the page from being arbitrarily turned and to turn the page quickly. Moreover, the possibility that an important printed portion of the score is included in the portions accommodated in the slits 410L and 410R is low, and the possibility that the reading of the score is hindered is low.

<Modification>
Hereinafter, with reference to FIG. 3, the arrangement and shape variations (modifications) of the slits 410 </ b> L and 410 </ b> R will be described. FIG. 3 is a diagram illustrating variations (modifications) of the positions and shapes of the slits provided in the music stand according to the first embodiment.

  FIG. 3A is a diagram showing the above-described example in which two slits 410L and 410R are arranged in a V shape (inverted C shape).

  FIG. 3B is a diagram showing an example in which two slits 411L and 411R are arranged in a V-shape (reverse C-shape) that is vertically longer (longer in the vertical direction) than FIG. 3A. By arranging the slits vertically as shown in FIG. 3B, only the margin portion of the musical score is accommodated in the slit, and the possibility that the important printed portion of the musical score is hidden in the slit is reduced.

  FIG. 3C is a diagram showing an example in which two slits 412L and 412R are arranged in a V shape (inverted C shape) by making them horizontally longer (longer in the left-right direction) than FIG. 3A. By arranging the slits horizontally as shown in FIG. 3C, only the margin portion of the musical score is accommodated in the slit, and the possibility that the important printed portion of the musical score is hidden in the slit is reduced. In addition, by arranging the slits horizontally, it is possible to maintain the corners of various sizes of musical scores.

  FIG. 3D is a diagram illustrating an example in which a pair of slits 413LL and 413RR having a wide interval and a pair of slits 413L and 413R having a narrow interval are arranged in a V shape (reverse C shape). By forming a plurality of slit pairs with different intervals as shown in FIG.

  FIG. 3E is a diagram showing an example in which the lengths of the two slits 414L and 414R are longer than those in FIG. 3A and the like, and are arranged in a vertically long (long in the vertical direction) V shape (reverse C shape). As shown in FIG. 3E, by arranging the slits to be vertically long, the musical score can be held more reliably while keeping important printed portions of the musical score from being hidden. In addition, when the slits are lengthened and arranged vertically, the pages can be easily inserted and removed, and the pages can be turned more smoothly.

  FIG. 3F is a diagram showing an example in which two slits 415L and 415R are arranged in a V shape (inverted C shape) as a curve. It is assumed that the slit 415L is a curve curved like a bow along the lower left corner of the musical score, and the slit 415R is a curve curved like a bow along the lower right corner of the musical score. As shown in FIG. 3F, the score can be held more reliably by making the slit a curved line and increasing the contact length between the slit and the score. Further, by making the slit into a curved curve that follows the shape of the left and right lower corners of the musical score as shown in FIG. 3F, the possibility that an important printed portion of the musical score is hidden in the slit is reduced.

  FIG. 3G is a diagram illustrating an example in which the lengths of the two slits 416L and 416R are longer than those in FIG. 3A and the like, and both slits are arranged in parallel in the vertical direction. In the example of FIG. 3G, the two slits are not arranged in a V shape (inverted C shape). By making the slits long and arranging them parallel in the vertical direction as shown in FIG. 3G, the contact length between the slits and the score increases, and the score can be held more reliably. In the case of FIG. 3G, the slits 416L and 416R accommodate not only two corners at the left and right lower ends of the musical score but also two corners at the upper left and right upper ends of the musical score.

  FIG. 3H is a diagram showing an example in which the slit 417L has a crescent shape curved along the left edge and upper and lower ends of the musical score, and the slit 417R has a crescent shape curved along the right edge and upper and lower ends of the musical score. It is. By making the slit into a crescent-shaped curve as shown in FIG. 3H, the contact length between the slit and the score increases, and the score can be held more reliably. In addition, by making the slit curved in a crescent shape as shown in FIG. 3H, it is possible to hide only the upper, lower, left and right corners of the musical score, so that the important printed part of the musical score is in the slit. The possibility of hiding is reduced.

  FIG. 3I shows that the slit 418L is disposed at the lower left corner of the back surface portion 41 so that the left end is positioned at the upper end side of the back surface portion 41 with respect to the right end so that the slit can accommodate the lower left corner of the musical score. The figure which shows the example which inclined and arrange | positioned the slit 418R in the upper right corner of the back surface part 41 so that the left end may be located in the back surface part 41 upper end side rather than the right end, and the said slit can accommodate the upper right corner of a musical score. It is. Even when the slits are arranged in a shape other than the V shape (inverted C shape) as shown in FIG. 3I, the two slits can accommodate the left and right corners of the musical score (regardless of the upper end or the lower end). If possible, the same effect as the music stand illustrated in FIG. 3A is obtained.

  3J includes an example of a slit 419L having the same shape and the same arrangement as the slit 414L in FIG. 3E and a slit 419R having the same shape and the same arrangement as the slit 416R in FIG. FIG. As illustrated in FIG. 3J, even if the slits are arranged in a shape other than the V shape (inverted C shape) and the slits are arranged asymmetrically, the two slits are formed at the two left and right corners of the musical score ( If the upper end and the lower end can be accommodated, the same effect as the music stand illustrated in FIG. 3A can be obtained.

  The configuration shown in FIGS. 2 and 3 can be easily realized as long as it is a material capable of forming a long hole in the back surface portion 41. For example, even if a hardwood nameplate is used, a music stand 4 with a page press function is realized without using a page holding bar as a separate part and only through a long hole without using a process such as joining or turning. can do.

  Hereinafter, with reference to FIG. 4, the shape of the musical score when the musical score is inserted into the slit of the musical score holder according to the present embodiment and its modification will be described. FIG. 4 is a schematic cross-sectional view illustrating the shape of the musical score 8 when the musical score 8 is inserted into the slits 410L to 419L of the musical score holder 4 of the present embodiment and its modification. FIG. 4A is a schematic cross-sectional view illustrating the shape of the musical score 8 when there is no stepped portion. FIG. 4B is a schematic cross-sectional view illustrating the shape of the musical score 8 when a step portion is provided. FIG. 4C is a schematic cross-sectional view illustrating the shape of the musical score 8 when a stepped portion having a step d larger than that in FIG. 4B is provided. As illustrated in FIG. 4A, when the back surface portion 41 is formed of a flat surface, the music score 8 is currently opened by inserting and supporting the corners of the music score 8 into the slits 410L to 419L and 410R to 419R. It stabilizes in a state where it is bent so that the middle of each page swells forward. When the music score 8 is bent as described above, when the music score 8 is viewed from the front, the peripheral portion (corner portion) looks somewhat smaller than the central portion of each page. In addition, when the deflection is large, it may be difficult to insert and remove the musical score 8. In order to reduce the bending of the musical score, for example, as shown in FIG. 4B, front portions 42L and 42R positioned on the left and right front sides of the back surface portion 41 are provided, and slits 410L to 419L are provided in step portions 46L extending from the back surface portion 41 to the front portion 42L. The slits 410R to 419R may be provided in the stepped portion 46R extending from the back surface portion 41 to the front portion 42R (right side components are not shown). By providing the front portions 42L and 42R and providing the slits 410L to 419L and 410R to 419R in the step portions 46L and 46R, the bending of the musical score 8 is reduced. Thereby, the flatness of the music score 8 is ensured, and the music score 8 can be easily inserted and removed. For example, the thickness variation of a commercially available booklet is checked in advance, the step height d is determined in advance so as to be larger than the thickness of most of the scores, and the step height d is as shown in FIG. 4C. The front portions 42L and 42R may be provided based on the above. For example, the step height d can be set to 10 mm. In this case, the musical score 8 is hardly bent and the printed surface of the musical score 8 is held in a flat state.

<First Embodiment>
Hereinafter, the arrangement and shape of the slits 410L and 410R in FIG. 3A are adopted, the front portions 42L and 42R in FIG. 4B or 4C are adopted, and the musical score of the first embodiment is configured to have a bottom portion on which the musical score is placed. The stand will be described. The structure of the music stand according to the present embodiment will be described with reference to FIGS. FIG. 5 is a perspective view of the music rest 1 according to this embodiment as viewed from the front surface. FIG. 6 is a perspective view of the music rest 1 according to the present embodiment as viewed from the back surface (back surface).

  As shown in FIGS. 5 and 6, the music stand 1 of the present embodiment includes a rectangular plate-shaped back surface portion 11, a rectangular plate-shaped bottom portion 12 extending forward from the lower end of the back surface portion 11, and a back surface portion 11. It is the structure containing the substantially rectangular plate-shaped leg part 13 extended below from the lower end. The back portion 11, the bottom portion 12, and the leg portion 13 are all given a predetermined R at their corners.

  The leg portion 13 is provided with a mounting hole (not shown), and is attached to a predetermined vertical surface such as a keyboard instrument through the mounting hole. The angle formed between the back surface of the back surface portion 11 and the back surface of the leg portion 13 is narrowed to an angle slightly smaller than 180 °. Thereby, in a state where the musical score holder 1 is attached to a keyboard instrument or the like, the back surface portion 11 is fixed in a state of being slightly inclined backward. The rearward inclination angle of the back surface portion 11 is easy to support the back of the musical score and the cover, and is suitable for viewing the musical score. On the left end, the right end, and the upper end of the back surface portion 11, there are provided inclined surfaces 114 that are inclined in a direction in which the center of the surface of the back surface portion is convex (the center of the back surface is concave). A flat surface other than the inclined surface 114 surrounded by the inclined surface 114 is referred to as a musical score support surface 113. A front portion 112 </ b> L located in front of the music score support surface 113 is provided at the lower left corner of the music score support surface 113. For example, the front portion 112 </ b> L may be provided 10 mm ahead of the musical score support surface 113. A slit 111L is provided in a step portion 116L extending from the musical score support surface 113 to the front portion 112L. The front portion 112L has a right triangle shape with the lower left corner being a right angle. The step portion 116L has a rectangular shape with the oblique side of the front portion 112L as a long side. In the present embodiment, the entire step portion 116L is opened to form the slit 111L. This music stand has a symmetrical structure, and the right side has the same structure. Specifically, a right triangle-shaped front portion 112R positioned in front of the music score support surface 113 is provided at the lower right corner of the music score support surface 113, and a step portion 116R extending from the music score support surface 113 to the front portion 112R. The whole is opened to form a slit 111R. Small steps 115 are provided at the left and right connecting portions of the inclined surface 114 and the music score support surface 113 so that the surface of the music score support surface 113 is slightly lower. The height of the step 115 decreases as it goes to the upper end side of the musical score support surface 113, and the musical score support surface 113 and the inclined surface 114 are connected to each other at the upper end of the musical score support surface 113 without any difference in height.

  The bottom 12 is tapered so that its thickness decreases as it advances toward the tip. The length of the bottom portion 12 in the width direction can be, for example, about 20 mm or more. Most of the upper surface of the bottom portion 12 is a music score placement surface 121 having a shallow groove for preventing slipping.

  A pocket parallel to the front portions 112L and 112R may be provided behind the front portions 112L and 112R to form a pocket that accommodates the corners of the musical score. The reason for adopting the above-described configuration without adopting a pocket in the music rest 1 of the present embodiment is that it is easy to manufacture. Hereinafter, with reference to FIG. 7, the metal mold | die used for manufacture of the music stand 1 of this embodiment is demonstrated easily. FIG. 7 is a cross-sectional view of a mold for manufacturing the music rest 1 of this embodiment by resin integral molding. As shown in FIG. 7, only two molds, a female mold 2 and a male mold 3, are necessary for manufacturing the music rest 1 of the present embodiment. The female mold 2 and the male mold 3 are both two-way dies. The front portions 112L and 112R described above can be formed by the protruding portion 31 provided in the male die 3 and the depression 21 provided in the female die. When the upper surface of the protrusion 31 and the upper surface of the recess 21 are in contact with each other, the resin does not flow into the contact portion, and the slits 111L and 111R are formed.

  As described above, the music rest 1 according to the present embodiment can be manufactured by resin integral molding using a simple mold (mold with two directions removed), and does not require attachment of another part used for page pressing. In addition, the musical score holder 92 provided in the conventional musical score holder 9 shown in FIG. 1 and a page press having a similar structure can suppress a wider range in the vertical direction of each page of the musical score, and the open state of the musical score can be further improved. Stabilize. Further, unlike the conventional music stand 92, there is no obstruction in the area where the page passes during page turning, so that page turning is not hindered.

  According to the musical score holder 1 of the present embodiment, the slits 111L and 111R are provided by opening the entire stepped portions 116L and 116R having steps larger than the thickness of the musical score of a plurality of pages, so that the configuration described in FIGS. In comparison, the music score is less deformed, and the music score can be easily taken in and out of the slits 111L and 111R.

  Further, according to the music stand 1 of the present embodiment, the bottom 12 for placing the lower end of the music score 8 is provided, so that even if the slits 111L and 111R are not used, the music score is prevented from sliding off the music stand 1. it can.

  The music stand 1 of the present embodiment can be used as a common component for various top board-shaped electronic keyboard instruments. Even when the top board of the electronic keyboard instrument is a curved surface or has a step, and the musical score cannot be placed on the top board, the music stand 1 of the present embodiment is applied to the electronic keyboard instrument. By attaching, it is possible to place a booklet score and hold the page.
