Claims

[Scope of utility model registration request]

In a tape loading device that loads a tape onto the circumferential surface of a rotating head drum using a guide block that slides on a guide rail, the guide rail includes a sliding surface for sliding the guide block, and the guide block. A positioning reference surface is provided for positioning at the final position of loading, and a plurality of rolling elements are provided at the lower part of the guide block to roll on the sliding surface, and a positioning reference surface is placed on the positioning reference surface for positioning. a reference surface to be positioned, and during loading of the guide block, the rolling element is moved on the sliding surface so that the reference surface to be positioned is spaced apart from the sliding surface. Further, at the final position of loading, the rolling element is separated from the sliding surface, while the reference surface to be positioned is placed on the positioning reference surface for positioning. tape loading device.
