Description

Technical Field

[0001] The present invention relates to a device for presenting sheet music on a transparent plate provided in space, which is combined with a page-turning device capable of turning the sheet music, and presents the sheet music on the transparent plate so as to be visible only to the performer, while at the same time enabling the sheet music to be turned.

Background Art

[0002] It is essential for singers, instrumentalists, etc. to look at sheet music during a music performance or concert. However, such sheet music is made of paper, and a bundle of paper sheet music is heavy and expensive to produce. Each time a performance is carried out, a person who turns the pages of the sheet music, that is, a page turner, has to turn the pages one by one horizontally.

[0003] In addition, the use of electronic sheet music utilizing a tablet PC is increasing, but this also has the inconvenience that it has to be touched by hand and turned during the performance.

[0004] The size of a music stand for placing and viewing sheet music is very large, with a standard area of 49 cm × 32 cm. Therefore, with a music stand of such a size, the upper body of the performer is almost blocked.

[0005] As a result, the performer always positions the music stand downward and places the sheet music on the music stand to view it, and a problem occurs in that when performing, the performer has to view the sheet music with the head lowered. In particular, when shooting a performance scene on video or during a performance, the performer or singer needs to direct their line of sight towards the camera or the audience, but the direction in which the performer views the sheet music does not match the position of the camera or the audience.

[0006] Therefore, a new technology for solving the above problems is needed.

[0008] This invention provides a method for solving the aforementioned problems. [Means for solving the problem]

[0009] The spatial music stand device of the present invention has a page moving device attached to the bottom for moving the pages of a musical score video provided on a monitor, and at the rear end of the main body is a video monitor that is linked to a tablet PC or computer for displaying a musical score video, a lower support base provided at the rear of the main body, an upper support base provided above the lower support base so as to be height variable upward from inside the lower support base, a fixing part that fixes the upper support base so as to fix the height of the upper support base, and a translucent mirror provided on the upper support base so as to reflect the musical score on the video monitor toward the performer, and the performer's line of sight height, the center of the translucent mirror, the center of the reflecting mirror and the center of the video monitor are configured to lie on a single optical axis.

[0010] Furthermore, the spatial music stand device of the present invention is further equipped with a monitor insertion / removal slot at the rear of the main body, and is configured to allow individual performers to insert and remove a separate video monitor, such as a tablet PC, that they carry with them.

[0011] Furthermore, the spatial music stand device of the present invention is equipped with an image inversion device at the bottom of the translucent mirror, and is configured by combining an image monitor and a page moving device.

[0012] Furthermore, the spatial music stand device of the present invention further includes a camera support at one end of the upper support base, and the camera supported by the camera support base is positioned on the same optical axis as the performer's line of sight and the center of the translucent mirror, and its position is adjustable.

[0013] Furthermore, in the spatial music stand device of the present invention, the video monitor and the translucent mirror are composed of a single structure, and the translucent mirror is configured to be coupled to a variable camera support base whose length is variable in the front and rear directions, and is supported by an upper support base. [Effects of the Invention]

[0014] With this invention, the musical score image is visible only to the performer on a substrate such as transparent glass, while external spectators can view the performer through the transparent glass without their face or expressions being obscured. When filming the performance with a camera, the video musical score is visible only to the performer, and the performer's face can be seen through the transparent glass without being captured by the camera.

[0015] Therefore, it is possible to create an effect that allows the musical score to be presented in space.

[0016] Furthermore, the musical score image displayed on the monitor located at the bottom is projected so that it is upright in all directions (up, down, left, and right). The top and bottom are inverted by a reflector and reflected upwards at a 90° angle, and then reflected forward at a 90° angle towards the performer from the surface of a translucent mirror, thus creating an upright image. Therefore, the performer can view the musical score as an upright image with correct orientation (up, down, left, and right) at a comfortable eye position without needing a separate image inversion device.

[0017] Furthermore, the performer's line of sight, the center of the translucent mirror, the center of the reflecting mirror, and the center of the video monitor are all aligned on a single optical axis. By mounting a camera on the same optical axis behind the translucent mirror, the performer's line of sight as they view the sheet music coincides with the camera's line of sight. As a result, even if the performer only looks at the sheet music while playing, their line of sight will naturally align with the camera's.

[0018] By the same principle, the line of sight of the performer looking at the music score also coincides with the line of sight of the audience through the music score. In addition, the semi-transparent mirror is configured not to hide the face of the performer. That is, even if the performer plays while only looking at the music score, the audience can make eye contact with the performer.

[0019] Also, when the right pedal is stepped on by the page turning device provided at the bottom, the next page is provided as the page of the music score, and when the left pedal is stepped on, the previous page is provided again. Therefore, the performer can turn the music score while performing alone. Thus, even without a person specifically turning the music score, the performer can arbitrarily turn the music score, and can perform while only carrying a simple memory device without a heavy stack of music scores.

[0020] That is, the music score video is only visible to the performer on the reflecting surface of the semi-transparent mirror as shown in FIG. 1. The performance posture of the performer is visible to the camera or the audience through the semi-transparent mirror, and the performer can perform while turning the music score with the page turning device.

[0021] In addition, a monitor insertion port is further provided at the rear of the main body, and by configuring it so that a separate video monitor such as a tablet PC carried by each performer can be inserted and used, the performer can insert and use the personal tablet PC carried into the present invention.

[0022] In addition, a camera support base is further provided at one end of the upper support base. The camera provided on the camera support base is provided so as to be located on the same optical axis as the center of the semi-transparent mirror and the line of sight of the performer, and is provided so that its position can be changed. For this reason, if necessary, the performer can rotate the camera support base to shoot the performance scene, or rotate the camera support base again to change the position of the camera and perform while looking at the audience.

[0023] In addition, by configuring the video monitor and the semi-transparent mirror in one structure and coupling them to a variable camera support base with a variable length in the front-back direction and providing them on the upper support base, there is an advantage that sheet music can be viewed closely when playing musical instruments with a large occupied area such as a piano or drums.

Modes for Carrying Out the Invention

[0025] Figure 1 and Figure 2(a) are perspective views in which the present invention is implemented, and Figure 2(b) is a cross-sectional configuration diagram specifically explaining this.

[0026] As shown in Figure 1, Figure 2(a) and Figure 2(b), the present invention includes a main body 1 at the lower part and a video monitor 2a at the inner rear end thereof. The installation direction of the video monitor 2a is in a form where upright images can be viewed correctly in the up, down, left, and right directions.

[0027] In front of the video monitor 2a, a reflecting mirror 3 that reflects at an upward 45° angle is provided, and on the front surface part of the main body 1, a page moving device 4 that can turn the sheet music video projected on the video monitor 2a left and right is configured.

[0028] At the rear end part of the main body 1, upper and lower support bases are configured upward, and a lower support base 5 is provided at the lower part. By being drawn into it, an upper support base 6 with a variable height in the up and down directions is provided. In addition, a height fixing part 5a is configured at the upper end of the lower support base 5, and the height of the entire support base is fixed.

[0029] At the upper end of the upper support base 6, a translucent mirror 7 is provided, angled at 45°, so as to reflect the musical score image from the video monitor 2a, which is incident on it from the lower reflecting mirror 3, at a right angle towards the performer 8.

[0030] The video monitor 2a consists of a tablet PC with built-in computer functions, or a monitor that is connected to a separate small computer.

[0031] The page movement device 4 is connected to the computer section of the video monitor 2a, and can be connected and disconnected via wired or wireless connection.

[0032] As shown in Figures 1 and 2(a), this page-moving device 4 moves to the next page of the score when the right pedal 4b is pressed, and returns to the previous page of the score when the left pedal 4a is pressed.

[0033] The translucent mirror 7 is angled at 45°, allowing some of the incoming image to pass through and the other to be reflected by the inclined surface. The transmittance and reflectance are set to 50%:50% as a baseline, and can be adjusted to 80%:20% or 20%:80% depending on the application.

[0034] Furthermore, as shown in Figure 2(a), the rear end of the main unit 1 is provided with a monitor insertion / detachment slot 2, allowing the performer 8 to bring and attach or detach a tablet PC with sheet music built in separately for use.

[0035] Furthermore, if you are using a monitor with a built-in computer, you can simply bring and connect a memory device such as a USB drive and use it.

[0036] Generally, in a structure with only one reflective surface, the monitor's image is inverted at the top and bottom. If you mount the monitor upside down to correct the top and bottom orientation, then the left and right orientation will be reversed.

[0037] Therefore, since the image must be flipped either vertically, vertically, or horizontally, a separate image flipping device is required. Such an image flipping device results in reduced resolution and necessitates a separate power supply and a separate, expensive, and complex structure.

[0038] In the present invention, as shown in Figure 2(b), the image, which is upright on the video monitor 2a, is reflected upward by a reflector 3 positioned at a 45° angle on its front surface, and the top and bottom of the image are inverted.

[0039] The inverted image is reflected at a right angle to the performer 8 by the reflective surface of the translucent mirror 7 located at the top, and the top and bottom are then upright again. As a result, the performer 8 can see a musical score image with the top, bottom, left, and right sides upright. Therefore, a separate image inversion device is not required.

[0040] In this configuration, the central axis a of the video monitor 2a, the central axis a of the reflecting mirror 3, the central axis a of the translucent mirror 7, and the eye level of the performer 8 are all located on a single optical axis a.

[0041] Furthermore, when the camera 10 is positioned at the eye level and in a straight line position of the performer 8, that is, outside the back surface of the translucent mirror 7, the camera 10 is also positioned on the same optical axis a line as the eye level of the performer 8.

[0042] With this configuration, even if the performer 8 plays while only looking at the musical score image provided on the video monitor 2a, their line of sight will match that of the camera 10. In addition, the semi-transparent mirror 7 allows the audience at a distance to see through the performer's face, while the musical score image is only visible to the performer.

[0043] As shown in Figure 1, when performer 8 plays while looking at the sheet music in the translucent mirror 7, the sheet music becomes visible only to performer 8, and external audience members will see performer 8 with their gaze directly across the translucent mirror 7, allowing them to see performer 8's face and expressions. Furthermore, during video recording, the gaze of performer 8 looking at the sheet music will directly coincide with the gaze of camera 10.

[0044] In other words, even if performer 8 only looks at the sheet music, their gaze will align with that of camera 10 or the audience, resulting in an effect as if they were performing while directly looking at camera 10 and the audience, and providing natural gaze and facial expressions.

[0045] Therefore, performer 8 can naturally look at the sheet music while simultaneously looking at the audience and camera 10, and turn the pages of the sheet music while pressing the pedal on the main unit 1.

[0046] In other words, one person can turn the pages of the sheet music while playing, without needing a separate page-turner.

[0047] In this invention, as shown in Figure 2(b), when the upper support base 6 is raised to the eye level of the performer 8 and the height fixing part 5a is fixed so that the optical axis a, which is the center of the translucent mirror 7, coincides with the line of sight of the performer 8, the eye level of the performer 8, the center of the translucent mirror 7, the center of the reflecting mirror 3, and the center of the video monitor 2a naturally coincide on a single optical axis a.

[0048] Therefore, even without a separate video inversion device, the top, bottom, left, and right of the sheet music image on video monitor 2a and the filmed image of performer 8 will align, and the line of sight of performer 8 will align with the line of sight in the filmed image.

[0049] As shown in Figure 3(a), the present invention further includes a camera support base 9 on a part of the upper support base 6, which can accommodate a camera 10.

[0050] Such a camera support stand 9 is equipped with a camera 10 that rotates up, down, left, or right so that when shooting, the translucent mirror 7 and the camera 10 are on the same optical axis a. The camera support stand 9 is also equipped with a mechanism that allows the camera 10 to rotate to the left, right, up, or down and retract when not shooting, so that the camera 10 does not obstruct the performance of the performer 8.

[0051] In this configuration, a camera support 9 is provided at one end of the upper support base 6, and the camera 10 is positioned on the same optical axis a as the central axis a of the translucent mirror 7. With this position of the camera 10, the line of sight of the performer 8 looking at the musical score coincides with the line of sight of the camera 10.

[0052] With this camera support stand 9, by rotating the camera support stand 9 around the upper support stand 6 as its axis, it becomes possible for the performer 8 to simultaneously view the sheet music, turn the pages of the sheet music, play, and be filmed at the same time, depending on the direction of rotation.

[0053] Furthermore, by adding a microphone support stand 9a to the upper support stand 6 as shown in Figure 3(a), a microphone can be attached and used as needed, and when the microphone is not in use, the microphone support stand 9a can be rotated to the left, right, up, or down to be retracted.

[0054] This structure allows singers to sing to the audience and cameras while looking at sheet music, without the need for a separate microphone stand. The logic behind this is the same as the logic of the present invention described above.

[0055] Furthermore, as shown in Figure 3(b), the spatial music stand device is equipped with a horizontally movable platform 61 at one end of the upper support base 6, which rotates left and right and whose length is variable, a tablet PC 2d is mounted at its front end, and a translucent mirror 7 is mounted above it.

[0056] This configuration allows musicians to view the sheet music at a close distance when playing bulky instruments like drums or pianos. Even when playing from a distance, musicians can turn the pages of the sheet music close to them.

[0057] As shown in Figure 3(c), the image inversion device may be configured as a monitor for displaying sheet music, such as a tablet PC 2a, and linked with the page turning device 4.

[0058] In other words, the spatial music stand device shown in Figure 3(c) is characterized by combining a translucent mirror 7 and a page moving device 4 by including an image inversion device equipped with an upward-facing video monitor 2a or tablet PC 2a.

[0059] As shown in Figure 3(d), when playing an instrument such as a violin and viewing the sheet music downwards, an inclined support base 51 may be added to the lower end of the lower support base 5, a rotating part 52 may be provided at the lower rear end of the main body 1, and a page moving device 4 may be provided in front of it.

[0060] The page turning device 4 is equipped with left and right switches 4a and 4b, which can be pressed by hand. It can also be further equipped with pedals above the left and right switches 4a and 4b for added convenience. For performances that use both hands and feet, such as drumming, it can be equipped with a wireless device using a separate sensor.

[0061] Therefore, with this invention, the musical score is visible only to the performer, and the performer's performance is transparent, so that the performer's line of sight to view the score aligns with the camera's line of sight without obstruction, the audience can see the performer's performance without the line of sight obstruction of existing music stands, and the performer can turn the pages of the musical score while performing without the help of a separate page turner.
