Title: Guide member for magnetic tape cassette
Inventor: SHIBA HARUO
IPC: G11B23/087
Filed: 1987-08-21
Abstract: PURPOSE:To obtain a member with superior smoothness, size accuracy, strength, and frictional characteristic, by forming the titled guide member with a material in which a lubricant is filled in a liquid crystal polymer made of total aromatic polyester. CONSTITUTION:The guide member being brought into contact with a tape slidably is made of the material in which the lubricant is filled in the liquid crystal polymer made of the total aromatic polyester. The mold shrinkage ratio of the guide member is quite low at performing plastic molding, thereby, superior surface smoothness and size stability can be obtained. And since no complicated working process in case of using a metallic material is required, superior profitability can be obtained because only a plastic molding method can be used. Furthermore, since high strength is attached on the guide member, durability for the claw on a tape can be improved. Also, the travel stability of the tape can be improved due to a low friction coefficient.
