An agriculture assistance system includes a data setting unit configured or programmed to associate agricultural data at a predetermined position in an agricultural field to a plurality of areas set in the agricultural field, and to set the associated agricultural data as data corresponding to the respective areas, an area setting unit configured or programmed to set the areas in the agricultural field, and a map display unit configured or programmed to display the data corresponding to the respective areas. When the areas set by the area setting unit are changed, the data setting unit is configured or programmed to reassociate the data to the areas after the change.

Agriculture assistance system

An agriculture support system includes a data obtaining device to obtain at least one type of data among a plurality of types of data relating to planting of crops, a mesh setting device to allocate, as divided data, the data obtained by the data obtaining device to each of areas of an agricultural field in which the crops are planted, a first map display to relate, to a location of the agricultural field, the divided data allocated to each of the areas by the mesh setting device and to display the divided data as a first field map, a spreading setting device to set a spreading amount of spread substance in each of the areas based on the divided data of each of the areas, and a second map display to relate, to the location of the agricultural field, the spreading amount and to display the spreading amount.

A spinning reel includes a reel body, a handle, a spool shaft, a spool, a rotor, a reciprocating mechanism, and a clutch mechanism. The handle is rotatably disposed on the reel body. The spool shaft is supported by the reel body. The spool moves in an axial direction of the spool shaft together with the spool shaft. The rotor rotates about the spool by rotation of the handle and winds a fishing line around the spool. The reciprocating mechanism moves the spool shaft back and forth in the axial direction when the rotation of the handle is transmitted thereto. The clutch mechanism switches between a transmitting state to transmit the rotation of the handle to the reciprocating mechanism and a non-transmitting state to terminate the transmission. The reciprocating mechanism enables the spool shaft to move in the axial direction when the clutch mechanism is in the non-transmitting state.

A reciprocating mechanism for a fishing reel includes a first rotating body that rotates around a first axis extending in a direction perpendicular to a spool shaft, a second rotating body that rotates around a second axis disposed at a distance from the first rotating body in the spool shaft direction, and parallel to the first axis, a rotation transmission body bridged between the first rotating body and the second rotating body, and configured to circulate when a handle is rotated, and a movable body having a part engaging the rotation transmission body, the movable body reciprocating in the spool shaft direction together with the spool shaft, when the rotation transmission body is circulated, and when viewed from a direction along the first axis, a virtual straight line that connects the first axis and the second axis is inclined with respect to an axis of the spool shaft.

Reciprocating mechanism for a fishing reel

A reciprocating mechanism for a fishing reel includes a first rotating body, a second rotating body, a rotation transmission body, and a movable body. The first rotating body is configured to rotate in conjunction with a winding operation of a handle of the fishing reel. The second rotating body is arranged spaced apart from the first rotating body along a spool shaft direction in which a spool shaft of the fishing reel extends. The rotation transmission body is bridged between the first rotating body and the second rotating body, and is configured to transmit the rotation of the first rotating body to the second rotating body. The movable body is configured to engage the rotation transmission body, and is configured to reciprocate in the spool shaft direction accompanying an actuation of the rotation transmission body.

A handle assembly is detachably screwed onto a master gear shaft, on which a master gear is provided. The handle assembly includes an approximately T-shaped handle grip, a handle arm on which the handle grip is rotatively mounted, and a handle shaft on which the base of the handle arm is mounted. The handle shaft has a three piece structure including a tubular main shaft unit, a first shaft portion that is screwed onto one end of the main shaft unit and the master gear shaft, and a second shaft portion that is mounted on the other end of the main shaft unit and the base of the handle arm. In a screw type handle assembly for a spinning reel, it is possible to maintain rigidity of the handle shaft at a high level while reducing the overall weight of the handle shaft.

A reel unit has a housing unit, a first lid, a second lid, and a rod-attachment portion. The housing unit has an accommodation space formed in the interior thereof that accommodates and supports a drive mechanism. The drive mechanism has a master gear non-rotatably coupled to a master gear shaft. The first lid is made of a metal and is fixedly coupled to the housing unit to interpose the master gear with the housing unit. The second lid is made of a synthetic resin and is fixedly coupled to the housing unit to close the accommodation space. The rod-attachment portion is formed integrally with the housing unit and can be mounted onto a fishing rod.

A master gear includes a shaft made of an aluminum alloy, a gear portion, and an annular member made of stainless steel alloy. The shaft is screwed onto a handle shaft, a gear portion that is integrally formed on the outer periphery of the shaft. The shaft is supported by the reel unit at rotational support portions via bearings and has female threaded portions on its ends such that the handle is screwed to one of the female threaded portions. The gear portion is arranged on an outer periphery of the shaft portion between the rotational support portions, and meshes with a pinion gear. The annular portion is mounted to the outer periphery of the shaft such that at least part of the annular member is disposed not between the rotational support portions. With this structure, it is easy to remove bearings from a master gear of a spinning reel.

A handle assemblyfor a spinning reel includes handle shafts, and a handle armthat is detachably mounted to a handle shaft. The handle armhas a through holeformed in the base end thereof. A male threaded portionof the handle shaftis mounted in the through hole, and the handle armis detachably installed on the handle shaftby a nut member. A cap memberthat covers the entire nut memberis mounted to the outer periphery of the nut member. A male threaded portionis formed on the tip of the cap member, and the cap memberis fixed to the nut memberby screwing the male threaded portionto a female threaded portionformed on a head portion of the nut member

Handle attachment structure for fishing reel

A rotor of a spinning reel includes a rotor unit, and a fishing line guide portion. The rotor unit has a body portion that is rotatably mounted on the reel unit, and first and second rotor arms that each extend forward from opposing positions on the outer peripheral surface of the body portion. The fishing line guide portion is mounted only on the first rotor arm. The first and second rotor arms are formed such that a line Ldrawn along the pivot center axis of the fishing line guide portion of and a line Ldrawn through the width-wise center of the second rotor arm and substantially parallel to the first line Lare on opposite sides of the rotational axis X of the body portion. A spinning reel rotor having a fishing line guide portion arranged on only one rotor arm can maintain rotational balance.

A spinning-reel reel unit has a housing unit, a first lid, a second lid, a rod-attachment portion, and a cover member. The housing unit has a housing space formed therein for accommodating and supporting a drive mechanism. The first lid is fixedly coupled to a side of the housing unit detachably/reattachably, and includes a first cover portion and a first cut-out. The second lid is fixedly coupled to another side of the housing unit detachably/reattachably, and includes a second cover portion and a second cut-out. The rod-attachment portion is formed integrally with the housing unit and is adapted to be mounted onto a fishing rod. The cover member covers both of the cut-outs of when the lids are fitted to the housing unit. In the spinning-reel reel unit, weight reduction can be achieved even when a cover member is provided.
