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.

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.

According to an embodiment, a signal generation device includes a memory storing a program and a processor communicatively connected to the memory and executing the program to function as a signal generating unit and a sound generation control unit. The signal generating unit generates a sound signal in response to operation of a plurality of operators. The plurality of operators includes a first operator and a second operator. The sound generation control unit controls a sound generation form of a second sound signal generated in response to a second operation of the second operator following a first operation, based on a duration of the first operation of the first operator.

The invention relates to a pedalboard system for musical instruments. The pedalboard consists of a main board comprising a main board base and a cover, and a plurality of pedal bases. The main board base contains a power supply which distributes power throughout a circuit comprising of female connection parts that extend into a plurality of openings in the mainboard cover. The openings act as pedal base attachment regions where, at each, a female connection part is accessible. The number of pedal attachment regions corresponds to the maximum number of pedals that can attach to the pedalboard. Each pedal base has a male connection part extending from the underside of the pedal base that allows it to attach to the female connection part on the mainboard base through the pedal attachment region on the main board cover. Each pedal base also comprises a pair of connection cables on the top side extending from the wire housing that enables the pedal base to connect to inputs and outputs of a musical pedal. When a pedal attaches to a pedal base, and the pedal base connects to the main board, the pedal is incorporated into the circuit of the main board. The pedalboard system enables pedals to easily detach, attach, and rearrange across the pedalboard to meet the user's needs.

A pedal device includes a pedal case including an opening portion, a pedal projecting outwards of the pedal case via the opening portion and provided rotatably, and a restricting portion including a first restricting surface which inclines along a downward gradient from a proximal end side towards a distal end side of the pedal on a side of the pedal case where the opening portion is formed and of which at least a part is provided on an upper surface of the pedal inside the pedal case.

A pedal device has a pedal case including an opening portion, a base member on which the pedal case is provided, a pedal projecting outwards of the pedal case via the opening portion and provided rotatably by a rotational shaft supported by a bearing portion provided on the base member, and a pedal leg portion provided on the base member, including a setting member provided in such a manner as to be brought into abutment with a setting surface, and projecting outwards of the pedal case on a side where the pedal projects.

A keyboard device for a keyboard instrument, capable of causing a cushion to properly function while suppressing generation of noise when a hammer contacts the cushion. The hammer is vertically pivotally moved in a manner interlocked with key depression. The cushion is provided below the hammer. In a key-released state, a contact portion of the hammer is placed on the cushion, and when the hammer pivotally moved upward by key depression returns to its original position by key release, the contact portion contacts the cushion from above. The contact portion is formed to be inclined in the front or rear direction with respect to the upper surface of the cushion when contacting the cushion. The hammer has a deformation suppressing portion provided on the contact portion and/or its vicinity, for suppressing deformation of the cushion in the front-rear direction when contacting the cushion.

A keyboard device for a keyboard instrument includes a keyboard chassis, keys disposed on the keyboard chassis, and a key support mechanism which is provided so as to support the keys from below, and causes, upon depression of a key, the depressed key to operate such that the key pivotally moves about a virtual pivot located rearward of a rear end of the key. The keyboard chassis includes a key stopper with which a rear end of an associated key moves into contact from below when the key returns to its original position before the key depression. The key includes a contact surface for contacting the key stopper in a key-released state, and a protrusion formed to protrude upward from the contact surface. At least one of the key stopper and the protrusion is disposed in plurality along a longitudinal direction of the key.

A key for a keyboard device includes a resin key body and one or a plurality of woody boards attached along at least part of a pair of side portions of the key body. The key body includes an upper portion protrusion which extends along an upper end of each of the side portions and is formed continuous with the top portion, the upper portion protrusion protruding in a lateral direction of the key body. Each woody board is disposed such that an upper end surface thereof is in contact with a lower surface of the upper portion protrusion. The upper portion protrusion has a thickness dimension in a vertical direction smaller than a thickness dimension of the top portion of the key body.

A keyboard device for a keyboard includes a hammer vertically pivotally moved in a manner interlocked with a key having been depressed, and a cushion provided below the hammer, the hammer contacting the cushion from above when the hammer having been pivotally moved upward in accordance with depression of the key returns to an original position in accordance with release of the key. The hammer includes a plurality of protrusions formed at respective spaced location in a rearward sequence from a hammer support shaft, such that they each extend downward. The cushion is formed by a plurality of cushions sequentially contacted by the plurality of protrusions, when the hammer contacts the cushion from above, in order from a protrusion closest to the hammer support shaft toward a protrusion remotest from the hammer support shaft.
