BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to a tuner mounting device for mounting a tuner to a musical instrument. 
   2. Description of the Related Art 
   As a mounting device for a conventional tuner which is directly mounted to an instrument, and which displays the tuning state of a sound generated from the instrument on a display portion, there has widely been adopted a clip type device which is mainly of a clothespin-like configuration (see, for example, JP 2003-255932 A). 
   A tuner of this type has in its main body a vibration sensor and a microphone as main input devices. 
   In many cases a generally used clip type tuner has a joint-like structure in a connecting portion between the clip portion and the main body portion. 
   This is due to the necessity to direct the display portion such that it is easily visible to the user when the clip is mounted to the instrument. In many cases, such a clip type tuner has a joint mechanism of two or more axes. 
   As illustrated in  FIG. 25 , a clip-type tuner is mounted to a part of an instrument  600  by the grasping force of a clip  100  connected to a tuner main body. 
   The clip  100  includes a pair of arms  101  and  102  having grasping portions  103  and  104  on the inner sides of the respective distal end portions thereof, and an opening/closing portion  105  containing an elastic member such as a spring urging the pair of arms  101  and  102  so as to close the distal end portions of the pair of arms  101  and  102 . 
   Since the instrument part (e.g., head portion of a guitar)  600  is held between the distal end portions of the arms  101  and  102  by the urging force of the elastic member (not shown) constituting the opening/closing portion  105  of the clip  100 , when the instrument part  600  is inserted to a position where it is brought into contact with the opening/closing portion  105 , which is a hard structure situated at the depth of the clip, with the distal end portions of the arms  101  and  102  of the clip  100  being open, there is a risk that the instrument is scratched. 
   In order that the instrument to which the tuner is mounted may not easily be scratched, the grasping portions  103  and  104  provided on the inner sides of the distal end portions of the pair of arms  101  and  102  of the clip  100  are often formed of a soft material such as rubber. 
   When, for example, rubber is used as the material of the grasping portions  103  and  104 , there is a risk that the rubber is allowed to be rubbed off on the instrument depending upon the kind of rubber, thus staining the expensive instrument. 
   Further, in the case of the clip-type instrument, it cannot be mounted to a large object whose side is beyond the movable range of the opening/closing portion  105  of the clip. As illustrated in  FIG. 26 , in the case, in particular, of a fat-tube instrument like a bass instrument, the mounting of the tuner to a fat tube portion  601  may be rather difficult to perform. 
   Many generally used clip-type tuners have a joint mechanism of two axes or more, and contain a vibration sensor for detecting vibration generated upon operation of the instrument and transmitted therefrom.  FIGS. 27 and 28  schematically illustrate the construction of a tuner in which a tuner main body  700  is connected to the clip  100  via a connecting portion  702  containing a joint mechanism. 
     FIG. 28  illustrates how vibration generated from the instrument is propagated via the clip  100  to a vibration sensor  701  contained in the tuner main body  700 . 
   In  FIGS. 27 and 28 , the tuner main body  70  is fixed to the instrument part (e.g., head portion of a guitar)  600  by means of the clip  100 . 
   When the instrument is operated in this state, vibration  250  generated from the instrument is propagated, as illustrated in  FIG. 28 , in the following order: the instrument part  600  to which the tuner main body  700  is fixed by the clip  100 , the clip  100 , the connecting portion  702  (joint mechanism), and the vibration sensor  701  in the tuner main body  700 . When there exist rubber, a hinge, a joint mechanism, etc. in the propagation route for the vibration  250 , the vibration  250  generated from the instrument is attenuated at this joint mechanism portion, making it rather difficult in some cases to obtain a sufficient sensitivity for the tuner. In particular, in an instrument in which the vibration generated through playing quickly attenuates as in the case of a string instrument, the failure to obtain a sufficient sensitivity may prove fatal to the tuning performance of the product. 
   In order to improve the sensitivity of a clip-type tuner, it is more important to provide the tuner on the clip side so that the tuner is close to the instrument during use of the tuner, than to provide within the tuner main body a vibration sensor for detecting the vibration generated from the instrument. This is due to the fact that the larger the length of the propagation route for the vibration  250 , the larger the degree to which the vibration  250  is attenuated. 
   When, in the clip-type tuner, it is necessary to provide a vibration sensor on the clip side, it is necessary to electrically connect the vibration sensor provided on the clip side and an electronic circuit contained in the tuner main body. However, as described above, the joint mechanism exists between the clip and the tuner main body, and the joint mechanism, which is freely movable, constitutes an obstacle to attaining electrical connection. 
   At present, the commercially available clip-type tuners that are provided with a vibration sensor on the clip side have a connecting portion of a very complicated structure between the clip and the tuner main body. Due to the complicated structure of the connecting portion between the clip and the tuner main body, the clip-type tuner provided with a vibration sensor on the clip side is subject to failure, resulting in many claims from the users and high cost due to its structure. 
   SUMMARY OF THE INVENTION 
   The present invention has been made in view of the above-mentioned problems in the related art. It is an object of the present invention to provide a tuner mounting device which does not scratch the instrument and which provides a satisfactory sensitivity to the vibration generated from the instrument. 
   In order to achieve the above-mentioned object, a tuner mounting device according to the present invention includes a tuner mounting device for mounting a tuner to be attached to an instrument, in which a tuner main body is fixed to a part of the instrument by a hook-and-loop fastener. 
   In the tuner mounting device of the present invention constructed as described above, the tuner main body is fixed to the part of the instrument by the hook-and-loop fastener 
   In this way, in the present invention, the hook-and-loop fastener is used as the mounting device, which means there is used a material softer than the clip of the conventional device; thus, when fixing the tuner to the target instrument, the possibility of the instrument being scratched or the material being rubbed off on the instrument like rubber is low, and hence the user is free from care when using the device. 
   Further, when the tuner is fixed to the instrument by a hook-and-loop fastener as in the case of the tuner mounting device of the present invention, the mounting possible regardless of the size of the instrument through adjustment of the length of the hook-and-loop fastener, and hence it is possible to attain a high degree of freedom in terms of the size of the instrument to which the tuner mounting device is applied. 
   Further, since the tuner main body can be mounted to the hook-and-loop fastener, it is possible to mount the tuner main body at a position nearest to the instrument when compared with the conventional clip-type device, and, there exists no joint mechanism in between as in the conventional clip-type device. Thus, the vibration propagation distance to the vibration sensor is reduced, whereby the attenuation of the vibration generated through operation of the instrument is mitigated, and the sensitivity of the tuner is improved. 
   Further, in the tuner mounting device of the present invention, a vibration sensor for detecting vibration generated through operation of the instrument is contained in the tuner main body.

   Further, by providing the hook-and-loop fastener with a plurality of vibration sensors, it is possible to achieve higher tuner sensitivity.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   In the following, embodiments of the present invention are described with reference to the drawings. Tuner mounting devices according to embodiments of the present invention basically use a hook-and-loop fastener instead of the conventional clip-type clip of the tuner mounting device. 
     FIGS. 1A and 1B  illustrate how a hook-and-loop fastener is fixed to a part of an instrument through wrapping and fastening;  FIG. 1A  illustrates how a hook-and-loop fastener  2  is fixed, for example, to a head portion  1  of a guitar through wrapping and fastening, and  FIG. 1B  illustrates how the hook-and-loop fastener  2  is fixed, for example, to a fat tubular portion  1 A of a bass instrument through wrapping and fastening. 
   First Embodiment  
     FIGS. 2A and 2B  illustrate the construction of a tuner mounting device according to a first embodiment of the present invention. In this embodiment, the tuner main body is fixed to a part of an instrument (e.g., the head portion of a guitar) by a hook-and-loop fastener.  FIG. 2A  illustrates how a tuner main body  10  is fixed to a head portion  1  of a guitar by a hook-and-loop fastener  2 . In this example, the hook-and-loop fastener is affixed, for example, to the bottom portion of the tuner main body  10 , and the tuner main body  10  is placed on the guitar head portion around which a hook-and-loop fastener of a different kind is wrapped and fastened, whereby it is possible to fix the tuner main body  10  to the guitar head portion  1 . 
   Further, it is also possible to mount a member for belt insertion to the tuner main body  10 , and to pass the hook-and-loop fastener  2  wrapped and fastened around the guitar head portion  1  through the same, thereby fixing the tuner main body  10  to the guitar head portion  1  by wrapping and fastening the hook-and-loop fastener  2  so as to press the tuner main body to the guitar head portion  1 . 
   Here, the kind of hook-and-loop fastener used is one consisting of one surface which is raised in hook-like manner and another surface which is raised in loop-like manner arranged closely together. As is well known, they are attached together by being pressed against each other, and allow separation. 
   In the example illustrated in  FIG. 2A , a vibration sensor  20  for detecting vibration  50  generated through operation of the instrument is contained in the tuner main body  10 . 
   In the example of  FIG. 2A , a hook-and-loop fastener is used as a mounting device, and hence the material used is softer than the clip of the conventional device; thus, the possibility of the target instrument being scratched or the material being allowed to rubbed off on the instrument at the time of fixation of the tuner is low, making the user free of care when using the device. 
   Further, the tuner main body is fixed and mounted to an instrument by means of a hook-and-loop fastener, and hence the mounting is possible to regardless of the size of the instrument through adjustment of the length of the hook-and-loop fastener, which advantageously leads to a high degree of freedom in terms of the size of the target instrument. 
   Further, since the tuner main body can be mounted to the hook-and-loop fastener itself, it is possible to mount the tuner main body at a position nearest the instrument, and no joint mechanism exits in between as compared with the conventional clip-type device, and hence the propagation distance to the vibration sensor is reduced, and the vibration attenuation due to operation of the instrument is mitigated, making it possible to achieve an improvement in terms of the sensitivity of the tuner. 
   While in the example of the tuner mounting device illustrated in  FIG. 2A  the vibration sensor is contained in the tuner main body, because the tuner main body can be mounted to the hook-and-loop fastener itself, it is possible to mount the tuner main body at a position nearest to the instrument as compared with the clip-type conventional device, and no joint mechanism exists in between as in the clip-type conventional device, and hence the vibration propagation distance to the vibration sensor is reduced, and the attenuation of the vibration generated through operation of the instrument is mitigated, thereby improving the sensitivity of the tuner. 
   In the example illustrated in  FIG. 2B , a vibration sensor is provided on the hook-and-loop fastener  2  of the tuner mounting device, which fixes the tuner main body to a part of an instrument by means of the hook-and-loop fastener.
