A light detection device includes a Fabry-Perot interference filter, a light detector, a spacer that has a placement surface on which a portion outside a light transmission region in a bottom surface of the interference filter is placed, and an adhesive member that adheres the interference filter and the spacer to each other. Elastic modulus of the adhesive member is smaller than elastic modulus of the spacer. At least a part of a lateral surface of the interference filter is located on the placement surface such that a part of the placement surface of the spacer is disposed outside the lateral surface. The adhesive member is disposed in a corner portion formed by the lateral surface of the interference filter and the part of the placement surface of the spacer and contacts each of the lateral surface and the part of the placement surface.

A connection substrateincludes a base materialformed by stacking a plurality of dielectric layerstoand a plurality of through conductorsprovided penetrating through the dielectric layerstoadjacent to each other. A plurality of radiation shielding filmstoformed integrally with each of the plurality of through conductorsand separated from each other are provided at two or more interlayer parts in the dielectric layersto. A region PRof the radiation shielding film() formed integrally with one through conductorin one interlayer part projected onto a virtual plane normal to a predetermined direction and a region of the radiation shielding filmor() formed integrally with another through conductorin another interlayer part projected onto the virtual plane do not overlap each other. Accordingly, the readout circuits of an integrated circuit device can be protected from radiation, and an increase in parasitic capacitance can be suppressed.

A tone generator includes a plurality of tone generation channels each comprising one or more operation channels. One operation channel performs basic operation of a tone signal computing operation (e.g., FM or AM) and a tone signal is generated by using one or more operation channels for one tone generation channel. Tone generation channels in the tone generator are established according to a selected performance mode. In a first mode, the operation channels are divided into N groups and N tone generation channels are established in correspondence to the respective operation channel groups. In a second mode, the operation channels are divided into M groups and M tone generation channels are established in correspondence to the respective operation channel groups wherein N is a different number from M. Tone generation channels of the number required according to the selected performance mode can be established by efficiently utilizing the operation channels of a limited number.

An apparatus for controlling the transport of a magnetic tape in a tape recorder or like devices, arranged so that a braking force is applied only for a predetermined length of time to reel stands carrying tape reels either when the tape transport is to be stopped or when a speed of the tape transport is to be reduced to thereby mitigate the consumption of electric power required for the braking action, the apparatus also eliminates the provision of a special operation for stopping the transport of the magnetic tape which, otherwise, is required for switching from high-speed run to normal-speed run of the tape.

An operation mode switching system for a tape recorder in which the tape recorder is set to a recording-pause mode by operating a REC. STBY. (recording stand-by) key when the tape recorder is in a stop mode, set to a recording mode by operating a PLAY key when the tape recorder is in the recording-pause mode, and set to a playback mode by operating the PLAY key when the tape recorder is in a stop, fast-forward or rewinding mode.

In an electronic musical instrument, an expression control circuit constituted by a first variable resistor is connected in the path of the tone signal. A second variable resistor is connected in series with or in parallel to the first. A third variable resistor is connected in shunt between the output side of the expression control circuit and the ground. The second and the third variable resistors can adjust the variation range of the tone signal at the output of the first variable resistance.
