    摘要: A reel comprises a hub onto which recording tape is wound and a flange that is disposed on an end portion of the hub and retains a width-direction end portion of the recording tape, wherein plural cutout portions that locally divide the hub and the flange are formed in the flange. The cross section of the hub in plan view has a substantially equilateral triangular shape and positions where constricting force resulting from the tape reaches a maximum are caused to protrude in advance.

    摘要: Retention portions that retain a leader member of recording tape are formed inside a case, and a spring member pushes the leader member toward the retention portions. The spring member contacts support point members, and the support point members serve as support points when the spring member deforms. The support point members, which are disposed such that they protrude from side walls of the case, include a height D1 from an inner surface (attachment reference surface) of the side walls. The spring member is bent such that its height at positions contacting the support point members from the attachment reference surface includes a height D2 in a state where the spring member is not attached to the case. Here, D2≦D1. When the spring member is attached to the case, the spring member always contacts the support point members. Thus, the pushing force of the spring member is stable.

    摘要: In a metal mold, a part of a portion corresponding to a reel gear in a bottom portion side of a hub is divided, and a gate port of a resin is provided in this portion. A flow path of the resin to the gate port is inclined in a peripheral direction with respect to an axial direction of the hub. The resin is guided by the flow path. In the hub, an orientation of the resin (a flow of the resin) is inclined in the peripheral direction with respect to the axis of the hub, and in a lower flange, the orientation of the resin is inclined with respect to a direction of a radial line of the lower flange.

    摘要: A reel is disposed with a reel hub made of resin whose outer peripheral surface is configured as a tape take-up surface and a reinforcement ring that is integrated with the reel hub by insert molding. On a bottom plate of the reel hub, there are formed: marks of gates that are disposed on a radial direction inner side with respect to the reinforcement ring and are used for injecting, into a die, a resin material that molds the reel hub; and at least one of thick portions that are positioned on the reinforcement ring side with respect to the marks of the gates and thin portions that are positioned on both sides, in a circumferential direction of the reel hub, with respect to the marks of the gates.
