Provided is an instrument housing case, which allows an instrument to be readily taken in and out of the instrument. The instrument housing case (10) includes: a main body case (20), which has a bottomed cylindrical shape, and includes an opened upper end surface and opened upper portions of parts of side surfaces; and a cover body (30). The cover body (30) includes: a top plate (31) adapted for an opening portion (26) of the upper end of the main body case; and a side plate (33) adapted for an opening portion (28) of parts of the sides of the main body case (20), the side plate (33) including a lower end portion pivotably fixed to the main body case (20) through a hinge (40). The cover body (30) covers the opening portion (26) of the upper end surface and the opening portion (28) of the parts of the sides of the main body case (20) to thereby allow the opening portions (26, 28) to open and close.

A locking device for retaining a musical instrument can be attached to a stand assembly by a base member. A support unit with an entrance opening supports a portion of the instrument. A force such as gravitational can cause the support unit to rotate a biased locking member to close the entrance opening. Removal of the instrument permits a biasing force to open the locking member.

An operating device for use with a musical instrument may allow for a supporting member configured to be supported by a user to be operatively connected to a percussion instrument with a case, which may contain an electronic circuit for processing a signal produced by striking a striking surface of the percussion instrument. The case may be arranged between the electronic percussion instrument and the supporting member. The case and the electronic percussion instrument may be configured to be moveable relative to the user.

Die Erfindung betrifft eine Haltevorrichtung für ein Saiteninstrument, die ein Gehäuse mit zwei gabelförmig angeordneten Haltearmen aufweist, wobei mindestens ein Haltearm um eine Längsachse drehbar ist und so mit einem Halteabschnitt auf den anderen Haltearm zu bewegbar ist.

Um das Einbringen eines Instruments zu vereinfachen, ist eine Rückstelleinrichtung vorgesehen, die an den Haltearmen exzentrisch angreift und ein rückstellendes Moment einbringt.

To provide a portable chord producing device capable of producing chord sounds by a simple operation.

In or on a housing 10 of a portable size, an operation switch 121 with which eight different chord sounds can be designated, and a display screen 11 which also serves as a touch sensor panel are formed. A memory card 20 has a chord data file recorded thereon that is used for letting chord sounds that have characteristics of sounds on a real musical instruments be produced. The chord producing device produces the chord sounds designated by the operation switch 121 through a sound production mechanism in a manner that is associated with a specific touch operation only during the time when it is selected.

The present invention provides a portable casing for carrying instrument (I), particularly musical instrument, very securely. The casing interior is provided with flexible shock absorbing supports (2) on which the non-vulnerable portions of the instrument are laid whereas the delicate and vulnerable portions are held suspended in mid-air. As soon as the casing is closed, the supports get deformed acquiring a loop-shaped structure to encircle and cradle the instrument - parts which overlie thereon and in doing so the instrument is rendered securely captive against any movement. In case of accidental impact the stress generated is borne by the soft lining (1) of the casing and by the shock absorbing supports, rendering the instrument unharmed. The shock absorbing supports are advantageously detachably secured to the inner walls of the casing by retaining means. The present invention also provides a method for housing instrument in a portable casing for transportation.

A sound control apparatus for a keyboard-based musical instrument for avoiding a touch of a shutter (6) to a back check (17), thereby appropriately setting a sound generation timing and maintaining a satisfactory touch feeling. The sound control apparatus comprises a shutter (6) integrated with a hammer (5) adapted to swing associated with a swinging motion of a key (4), extending along a plane including a path along which said hammer swings, and formed with a cutout in an edge on an opposite side to a direction in which said hammer swings. An optical sensor (7,8) has a light emitter disposed on one side of the swinging path of said shutter for emitting light, and a light receiver disposed on the other side of the swinging path for receiving the light from said light emitter, and generates a detection signal in accordance with a light receiving state of said light receiver. A CPU sets a sound generation timing at which music sound should be generated based on the detection signal of said optical sensor responsive to opening and closing of a light path of the light from said light emitter of said optical sensor (7,8) by said shutter (6), when said hammer (5) swings.

A method and apparatus for outputting audio data and a musical score image, displaying a musical score image corresponding to reproduced audio data, and outputting audio data corresponding to a musical score image are provided, in which a tone is extracted, the tone is converted into a frequency, a monotone or polyphonic tone is identified, the frequency corresponding to a monotone or polyphonic tone is converted into tone information data, and the tone information data is stored, and a musical score is displayed. Also, audio data corresponding to a musical score are output, in which the musical score is photographed, musical signs from the photographed musical score are extracted, a pitch of a tone is extracted from music paper and musical note information of the musical signs, a duration of the tone from the musical note information of the musical signs is extracted, and audio data are output.

Es wird eine Trommel karre (1) für die Halterung und die Bewegung einer Trommel (2) mit und auf einem Gestell (3) und einem Hüftgurt (4) auf zwei Rädern (5), dadurch gekennzeichnet, dass die Trommel (2) von mindestens einem Bügel (6) um die Zarge (7) erfasst und vorzugsweise mit zwei Gelenken (8) mit dem Bügel (6) verbunden ist und der Bügel (6) vorzugsweise in ihre Mitte mit dem Gestell (3) befestigt wird, so dass der Spieler (9) mit beiden Schlägeln (10) das Schlagfell (14) den Schlagfell (14) vertikal trifft.

A speed detecting apparatus for a keyboard musical instrument is provided for accurately detecting the speed of pivotal movements of a hammer and a key even if a shutter implies errors in its attachment, without affected by such errors. The speed detecting apparatus for a keyboard musical instrument comprises a pivotable key (4), a hammer (5) pivotably supported by a fulcrum and configured to pivotally move in association with a pivotal movement of the key, a shutter (6) integrally attached to the hammer, a plurality of detectors (7,8), each having a light emitter and a light receiver for receiving light emitted from the light emitter, arranged on one and the other sides of the pivotal movement path of the shutter, and a CPU for detecting a pivot speed of the hammer in response to timings at which the shutter opens and closes the light paths of the light of the plurality of detectors when the hammer pivotally moves. The plurality of detectors have detection points on respective light paths of the light from the light emitters, and are arranged such that the detection points are positioned on an arc centered at the fulcrum of the hammer.
