RESIN CASTING MOLD, MOLDED RESIN PRODUCT, OPTICAL ELEMENT, OPTICAL SCANNING DEVICE, AND IMAGE FORMING APPARATUS |
| 摘要 |
A resin casting mold includes a mold member forming a cavity that includes first and second surfaces facing each other in a first direction. The mold member further includes an insert member which forms a part of a third surface and which is slidable in a second direction perpendicular to the first direction. At least one cross-sectional shape of the cavity satisfies h<A<H, where “A” is the length of the insert member in the first direction, “h” is a spacing in the first direction between a portion of the first surface closest to the insert member and a portion of the second surface closet to the insert member, and “H” is the length in the first direction on the third surface. The insert member is disposed to include a region having the spacing “h”.
