Title: Recording medium housing cassette
Inventor: SHIMOGUNI KENJI
IPC: G11B23/113
Filed: 1995-10-30
Abstract: PROBLEM TO BE SOLVED: To obtain a cassette casing having improved impact resistance by using GPPS(general purpose polystyrene) as a chief material for the forming material of the cassette casing and using materials having excellent impact resistance in combination as a master batch material. SOLUTION: The cassette casing 1 consists of an upper half 2 and a lower half 3 which are molded by resin materials. The master batch material B (dark colored material) is mixed with the chief material A and the mixture is charged into a hopper 21 of a molding machine 20. The cassette casing 1 is molded in a metal mold section 22. The colorless GPPS is used for the chief material A and the dark colored materials (HIPS, AS, ABS, etc.) having the excellent impact resistance are used for the master batch material B. The impact resistance is sufficiently assured with the molded cassette casing 1. The cassette casing is not damaged even the casing falls from a high place.  The excessively high contact of the materials having the impact resistance is the cause for unequal colors and the excessively low content does not improve the impact resistance and, therefore, the content is adequately 1 to 30wt.%.
