In a light emitting module, each of a first light wavelength conversion member, a second light wavelength conversion member, and a third light wavelength conversion member converts the wavelength of the light emitted by a semiconductor light emitting element to emit the light within a wavelength range different from the others. Each of the first light wavelength conversion member, the second light wavelength conversion member, and the third light wavelength conversion member is formed into a plate shape and is laminated such that the light emitted by the semiconductor light emitting element passes through each of them in descending order of the average wavelength of the light whose wavelength has been converted.

A plurality of disks are supported and rotated by a spindle motor in a case. A stabilizer is located in the case. The stabilizer has a stabilizer plate which is located between the disks and opposed to surfaces of the disks with gaps therebetween and a plurality of support portions which extend from the stabilizer plate outside the disks, are sandwiched between a bottom wall and a cover of the case, and support the stabilizer plate. A method of assembling the stabilizer plate includes positioning the stabilizer plate over a first magnetic disk and securing a support portion to a bottom wall or surface of the case, positioning a second magnetic disk over the stabilizer plate and then securing an upper cover of the case to the support portion.

A card-shaped electronic apparatus includes a base in the form of a substantially rectangular plate having a natural bending vibration mode, components mounted on the base, and covers attached to the base and covering the components. The base has a pair of side edge portions capable of being guided along a pair of guide rails of a card slot. Protrusions for determining the position where the base contacts the guide rails are located individually near positions corresponding to nodes of the bending vibration mode on each side edge portion, and project in the thickness direction of the base.
