Abstract: A music stand includes a plate having a through hole, a first member configured to be disposed on one side of a front surface or a back surface of the plate and having a projecting portion configured to be passed through the through hole, and a second member configured to be disposed on another side of the front surface or the back surface of the plate and having a recessed portion corresponding to the projecting portion.

Abstract: A button apparatus comprises a push member on which a push operation can be performed, an elastic member of a substantially hollowed shape provided on a push direction side of the push member and configured to be elastically deformed on a side thereof which faces the push member in response to the push operation performed on the push member, a detector configured to detect the push operation performed on the push member, and a moving member supported on the elastic member and configured to move in the push direction in response to the push operation performed on the push member, and a side of the elastic member which faces the detector is elastically deformed as a result of the moving member moving in response to the push operation.

Abstract: A manipulator includes a light source that emits light; a rotatable member that is rotatable around an axis; and an operation member having a substantially disk shape, attached to the rotatable member so as to be rotatable together with the rotatable member, the operation member including a light guide member that guides light incident from the light source, and a wheel member arranged on one plate surface side of the light guide member, wherein the rotatable member has a holding portion that holds the light guide member.

Abstract: A manipulator includes a case; an axis-having member having a rotatable member; an operation member attached to the rotatable member of the axis-having member so as to be rotatable together with the rotatable member; and a fixing member that fixes the axis-having member to the case, the fixing member having a flexible member that is attached to the axis-having member.

Abstract: A manipulator, comprises a light source that emits light; and an operation member rotationally operatable around an axis by a user, the operation member having a substantially disk shape and including a light guide member that guides light incident from the light source and emits the light to an outside in radical directions of the substantially disk shape from an outer peripheral portion thereof, and a reflecting member reflecting a portion of the light guided by the light guide member in a direction perpendicular to the radial directions at said outer peripheral portion.

Abstract: A rotating shaft housing structure of rotating members, including: a main body; rotating shafts for the rotating members; and a common recess which is provided in the main body, wherein the rotating members are attached to the main body via the respective rotating shafts so as to be rotatable, and the rotating shafts are housed alongside each other in the common recess.

Abstract: There is provided a recording and/or reproducing apparatus which may include a cassette insertion slot formed at a front panel, an opening/closing lid for opening/closing the cassette insertion slot, a cassette compartment, and cassette double insertion blocking means. The cassette compartment may include a cassette loading holder for loading and unloading a cassette inserted through the cassette insertion slot while pushing the opening/closing lid open inward by moving between a cassette loading position and a cassette ejecting position along a substantially L-shaped path extending horizontally and vertically.

Abstract: An automatic magnetic tape loading apparatus in a magnetic tape recording/playback system includes a reel support rotatably mounted in a first recess in a base for supporting an open feed reel, a takeup hub rotatably mounted in a second recess in the base for winding a magnetic tape fed from the open feed reel, and a channel defined in the base for passage therethrough of the magnetic tape as it is supplied from the open feed reel to the takeup hub. The base has thereon a plurality of air ducts for blowing air through the first recess and the channel into the second recess to carry a leading end portion of the magnetic tape from the open feed reel via the channel to the takeup hub until the leading tape end portion is coiled around the takeup hub.
