An optical reading device for a pointer instrument which has a pointer and a scale face or dial with different degrees of reflectance in each case, includes an illumination device for illuminating the scale face or dial and a plurality of light sensor elements which are arranged in a circular arc about the rotational axis of the pointer in order to detect the light of the illumination device reflected back by the scale face or dial, wherein the illumination device is configured to uniformly illuminate the scale face or dial and each light sensor element is configured with an isosceles triangle outline, where each light sensor element is offset with respect to one another by half of the base width in the circumferential direction of the circular arc.

A drum shell for enhancing the sound and tone qualities of a drum is provided. The drum shell has an outer band, an inner band, and an aerated core interposed therebetween. In one aspect, the core defines a plurality of spaces each providing a sound tube for vibrating air contained within the spaces.

A resin molded article is applied to a vehicle display device for displaying information on a vehicle, and a high gloss region having a relatively high surface glossiness and a low gloss region having a relatively low surface glossiness are integrally molded. As a result, since the high gloss region and the low gloss region having different surface glossiness are integrally formed in a single resin molded article 1, the resin molded article and the vehicle display device obtain an effect such that various appearances are created with a simple structure.

A step motor that drives a rotary body to rotate includes: an output shaft that outputs a rotational driving force to the rotary body, the output shaft having an insertion hole in which the rotary body is arranged so as to be integrally rotatable on an inner circumference side of a top portion of a tip end of the output shaft; a radial bearing radially supporting the output shaft from an outer circumference side; and a cover protruding from the radial bearing radially inward. The cover opposing the top portion through an axial gap at an outer circumference side of the insertion hole. The output shaft has an inner tapered portion which decreases in diameter as approaching the insertion hole radially inward from the top portion. The cover opposes the top portion through the axial gap at an outer circumference side of the inner tapered portion.

A vehicle display device pointer includes a translucent pointer that has a pointer main body disposed on a front side of a dial plate having a penetration hole and extending along the dial plate, a shaft protruding toward the penetration hole, and a light guide connecting the pointer main body and the shaft; a lightproof first shielding member that covers a proximal end portion of the pointer main body and the light guide from a front side and a lateral side; and a lightproof second shielding member that covers the proximal end portion of the pointer main body and the light guide from the back side. The pointer main body emits light by light emitted from a light source and incident on the shaft, and the second shielding member has protrusions that protrude toward the front side, and close gaps.
