Publication number: 20090172992Abstract: A fishing reel has a reel unit that is mounted on the fishing rod, a spool that is rotatably attached to the reel unit, a tension detector that detects tension applied to the said fishing line, and a communication portion that transmits to a fishing information display apparatus data of the tension applied to the fishing line detected by the tension detector. The fishing information display apparatus is provided externally of a fishing reel, and receives data communicated from the fishing reel. The fishing information display apparatus includes a body member, a display portion provided in the body member, a communication portion that receives from the fishing reel data of the tension applied to the fishing line, and a controller that is displays on the display portion the data of tension received from the fishing reel.

Patent number: 7165737Abstract: A spool braking device for a dual-bearing reel that applies a braking force to a spool during casting includes a spool brake unit, a switch element, a casting state detecting device and a spool control device. The spool brake unit is configured to brake the spool and includes a rotor having a plurality of magnets and a plurality of coils. The magnets are arranged along a rotational direction with alternating polarities. The coils are arranged to be spaced apart in a circumferential direction. The coils have end faces that are arranged to face a side face of the rotor. Each of the coils has a winding diameter that is larger than a full length of the coil. The casting state detecting device is configured to detect a casting state. The spool control device is configured to control an on/off status of the switch element based on the casting state.Type: GrantFiled: December 29, 2005Date of Patent: January 23, 2007Assignee: Shimano Inc.Inventors: Shouji Nakagawa, Takeshi Ikuta, Ken'ichi Kawasaki, Hiroaki Kuriyama

Patent number: 7070139Abstract: The reel unit of a dual-bearing reel includes a frame, first and second side covers, an operating lever, and guard members. The frame has first and second side plates and a connection member. The first side cover, to which the handle is mounted, is mounted to the first side plate. The second side cover is mounted to the second side plate in an inclined manner such that a fore end of the second side cover is closer to the second side plate. The operating lever is provided on the second side plate protruding inward from the second side plate. The second side cover is locked in a closed state when the operation portion assumes a second position, while the operation portion allows the second side cover to be opened and closed relative to the second side plate when the operation portion assumes a first position.Type: GrantFiled: April 12, 2005Date of Patent: July 4, 2006Assignee: Shimano Inc.Inventors: Shouji Nakagawa, Akira Nago
