  The case members 19 are fixed to the inner side surfaces of the side plates 7a and 7b of the reel body 1 by screws 38, respectively. The case member 19 includes, for example, a housing portion 24 having a rectangular first opening 24a having an entire lower surface opened on the lower surface and having a storage space SA therein, a front cover portion 25 extending forward from the housing portion 24, and a housing. And a rear cover portion 26 disposed behind the portion 24. The housing | casing part 24 has the upper surface part 24b and the wall part 24c arrange | positioned at four sides so that the lower surface of the upper surface part 24b may be enclosed. A lower portion of the wall portion 24c is a first opening 24a. Therefore, the first opening 24a is formed over the entire lower surface of the wall 24c.

  As shown in FIG. 4, the upper surface portion 24b has a substantially rectangular second opening 24d closed by the window member 22, and circular switch openings 24e and 24f for exposing the two switches SW1 and SW2. Is formed. The switch SW1 is a switch for 0 set, for example, and the switch SW2 is a switch for memory such as a shelf memo, for example. The switch openings 24e and 24f are arranged in the left-right direction behind the second opening 24d. A switch wall portion 24g having a larger diameter than the upper portion is formed in a cylindrical shape at the lower portion of the inner peripheral surface of the switch openings 24e and 24f. In the first opening 24a, a step portion 24h for positioning and arranging the lid member 21 is formed. On the upper surface portion 24b, a mounting portion 24i that protrudes inward to position and mount the window member 22 is formed to be slightly recessed from the upper surface. A second opening 24d and switch openings 24e and 24f are formed in the mounting portion 24i. Therefore, the mounting portion 24i is formed over the entire periphery on the inner peripheral side of the second opening 24d.

The spool rotation sensor is disposed outside the counter case 4.

  The switch SW1 includes a switch operating member 40 made of hard synthetic resin, and a tact switch 41 pressed by the switch operating member 40. The switch operation member 40 includes an operation portion 42 and an elastic spring portion 43 attached to the operation portion 42. The operation unit 42 is a slightly tapered columnar member, and a tip protrudes from the switch opening 24e in order to operate the switch SW1. The outer surface of the operation unit 42 is plated. The spring portion 43 includes an attachment portion 43a attached to the operation portion 42, an enlarged portion 43b formed integrally with the attachment portion 43a and extending from the attachment portion 43a to the inner peripheral surface on the large diameter side of the switch opening 24e, and the enlargement portion 43b. A seal portion 43c extending in a cylindrical shape from the edge portion and contacting the switch wall portion 24g. The mounting portion 43 a has a pressing portion 43 d that extends downward from the center portion and can press the tact switch 41. A tact switch 41 mounted on the upper surface of the circuit board 20 is disposed below the pressing portion 43d with a slight gap.

  The enlarged portion 43b extends in a plate shape with a small thickness from the periphery of the mounting portion 43a to a position in contact with the switch wall portion 24g. The enlarged portion 43b is provided to cover the gap from the mounting portion 43a to the switch wall portion 24g and to urge the operating portion 42 in a direction away from the circuit board 20. By such an action of the enlarged portion 43b, when the hand is released after the operation portion 42 is pressed, the operation portion 42 automatically returns in a direction away from the circuit board 20. The seal portion 43c is formed in a cylindrical shape so as to contact along the switch wall portion 24g. The close contact member 44 is in close contact with the inside of the seal portion 43c.

  The close contact member 44 is a metallic cylindrical member such as a stainless alloy, and has a shape along the seal portion 43c. The contact member 44 presses the seal portion 43c toward the switch wall portion 24g, thereby bringing the seal portion 43c into close contact with the switch wall portion 24g. As a result, even if the switch opening 24e is provided in the case member 19 in order to perform the switch operation, the liquid does not easily enter the case member 19 from the upper surface side. Moreover, since the seal portion 43c is pressed against the switch wall portion 24g by the contact member 44 and sealed, the number of screws for mounting the circuit board 20 can be reduced, and the circuit board can be mounted when the circuit board 20 is mounted. 20 becomes difficult to deform.

  As the synthetic resin used for the operation section 42, a synthetic resin such as an acrylic resin that is easily attached and difficult to peel off is preferable. Synthetic resin elastic bodies used for the spring portion 43 include styrene-butadiene-rubber (SBR), acrylonitrile-butadiene-rubber (NBR), butadiene-rubber, isoprene-rubber, chloroprene-rubber, silicon-rubber, urethane-rubber, etc. A synthetic rubber having the following insulating properties is preferred.

  In the switches SW <b> 1 and SW <b> 2 configured as described above, the switch operation member 40 is configured by a hard operation portion 42 and an elastic spring portion 43. For this reason, the design of the switch operation member 40 is not limited to the material of the spring part 43, and the design of the operation part 42 can be determined freely. For example, in this embodiment, the operation unit 42 is subjected to a plating process that cannot be performed on the elastic body. Also, any color can be expressed by the color of the paint or the material of the operation unit 42.

  The circuit board 20 is a substantially rectangular synthetic resin board, and is fixed to the LCD holder 27 by, for example, two screw members 38. The circuit board 20 is arranged at a distance from the lid member 21 by a substrate support member 29 placed on the lid member 21. Connected to the circuit board 20 are a liquid crystal display device (LCD) 30 which is an example of a display device, and two drive elements 31 formed of a field effect transistor (FET) for driving the motor 12. The circuit board 20 includes a control element 32 composed of a microcomputer for controlling the motor 12 and the liquid crystal display device, a light emitting element 33 composed of, for example, an LED functioning as a backlight of the liquid crystal display device 30, a battery 34, A diode 35 for preventing reverse connection of the battery, a buzzer 36 for notification, other electrical components such as a resistor and a capacitor, and a spool rotation sensor are connected. The battery 34 is, for example, a button battery and is used as a power source for an electric circuit. Thereby, when the motor 12 is not used, the electric reel functions as a manually wound counter reel. Here, on the upper surface of the circuit board 20, a control element 32, a tact switch 41, a light emitting element 33, and other electric components such as a resistor and a capacitor are arranged. On the lower surface of the circuit board 20, a driving element 31, a battery 34, a diode 35, a buzzer 36, and other electrical components are arranged. The circuit board 20 is fixed to the LCD holder 27 by a screw member 38.

  The substrate support member 29 is placed on the lid member 21. The substrate support member 29 has a plurality of protrusions 29 a for disposing the circuit substrate 20 away from the lid member 21. The substrate support member 29 is formed with an oval opening 29c and a circular opening 29d for allowing passage of a first curved portion 21a and a second curved portion 21b of the lid member 21 described later.

  Here, the circuit board 20 is placed on the board support member 29 and supported so as to be slightly movable. Further, the substrate support member 29 is merely placed on the lid member 21 and is not fixed to the lid member 21 by a fixing member such as a double-sided tape or a screw member. Furthermore, since the circuit board 20 is fixed to the LCD holder 27, the circuit board 20, the LCD holder 27, and the liquid crystal display device 30 are integrated. A substrate support member 29 is provided to prevent the integrated portion from being inclined when the lid member 21 is attached. That is, the board support member 29 functions as a spacer that fills the gap between the circuit board 20 and the lid member 21. The substrate support member 29 may be fixed to the lid member 21 with a double-sided tape or the like.

  The liquid crystal display device 30 is disposed so as to face the second opening 24d. The liquid crystal display device 30 is placed on a light guide plate 28 (described later) of the backlight 23 disposed on the upper surface of the circuit board, and is fixed to the light guide plate 28 with a double-sided tape 48. A cushion member 47 is disposed between the liquid crystal display device 30 and the lower surface of the upper surface portion 24 b of the case member 19. The light guide plate 28 is mounted on the LCD holder 27 and is fixed to a mounting surface 27 a described later by a double-sided tape 49. The LCD holder 27 includes a flat plate-like placement surface 27a on which the light guide plate 28 is placed, a plurality of (for example, four) leg portions 27b that protrude downward from the bottom surface of the placement surface 27a, and a light guide plate. 28, and a slit portion 27c into which a later-described reflecting portion 28a is fitted. As a result, the light guide plate 28 and the liquid crystal display device 30 are fixed to the LCD holder 27.

  In a conventional circuit board, two boards are used: a circuit board on which a circuit for a liquid crystal display device is mounted and a circuit board on which a circuit for a control element is mounted. However, in this embodiment, in order to reduce the size of the counter case 4, the circuit of the liquid crystal display device 30 and the circuit of the control element 32 including the drive element 31 are mounted on one circuit board 20. Therefore, the liquid crystal display device 30 can be placed on the LCD holder 27 together with the light guide plate 28, and a gap can be formed between the liquid crystal display device 30 and the upper surface of the circuit board 20. Thereby, a large electric element such as the control element 32 can be arranged in the gap, and the upper surface of the circuit board 20 can be used efficiently.

  A backlight 23 is disposed between the liquid crystal display device 30 and the LCD holder 27. The backlight 23 includes the light-emitting element 33 described above and a plate-like light guide plate 28 for efficiently guiding light from the light-emitting element 33 to the lower surface of the liquid crystal display device. The light emitting element 33 emits light upward (an example of a direction intersecting the first surface) away from the upper surface of the circuit board 20. For this reason, in this embodiment, the light guide plate 28 is formed in a flat L shape. The light guide plate 28 is a transparent optical element, and diffuses light by efficiently guiding it to the back surface of the liquid crystal display device 30 and diffusing it. Since the light emitting element 33 is mounted on the upper surface of the circuit board 20, the light emitting element 33 is arranged away from the liquid crystal display device 30. For this reason, in this embodiment, the light guide plate 28 includes a reflecting portion 28a disposed to face the light emitting element 33 and an irradiation portion 28b that is bent from the reflecting portion 28a and disposed on the lower surface of the liquid crystal display device 30. ,have. The reflection portion 28 a has a chamfered reflection surface 28 c inclined toward the liquid crystal display device 30 in the central portion excluding both side portions. For example, a white reflection sheet 28d is attached to the reflection surface 28c. By the reflection sheet 28d, the light emitted from the light emitting element 33 is refracted by 90 degrees and guided to the irradiation unit 28b. Instead of the reflection sheet 28d, a white paint may be applied to the reflection surface 28c.

  In the backlight 23 having such a configuration, the light emitted from the light emitting element 33 is emitted upward and intersects with the upper surface of the circuit board 20 as indicated by a dashed line arrow in FIG. Incident light. The light that has entered the reflecting portion 28a is bent 90 degrees by the reflecting portion 28a, travels toward the irradiating portion 28b, and is diffused and irradiated to the back side of the liquid crystal display device 30 by the irradiating portion 28b.

  The lid member 21 is a member formed by, for example, forming a thin plate member made of an aluminum alloy by press working. The lid member 21 is a member that is attached to the step portion 24 h of the first opening 24 a formed on the lower surface of the case member 19 and closes the first opening 24 a. The lid member 21 is bonded to the case member 19 by a seal member 52 having an adhesive function applied to the step portion 24h. The lid member 21 is fixed to the case member 19 by two screw members 39. The lid member 21 includes a first bending portion 21a and a second bending portion 21b that are bent upward. A driving element 31 mounted on the lower surface of the circuit board 20 is disposed close to the first bending portion 21a. A diode 35 for preventing reverse connection mounted on the lower surface of the circuit board 20 is disposed adjacent to the second bending portion 21b.

  The first curved portion 21a is formed in an oval shape in a direction approaching the circuit board 20, and has a cross-section with an isosceles trapezoid. The second curved portion 21b is formed to be recessed in a circular shape in a direction approaching the circuit board 20, and has a cross section of an isosceles triangle shape. The first bending portion 21a and the second bending portion 21b are formed by a mold by press molding. The first bending portion 21 a is recessed larger than the second bending portion 21 b in order to approach the drive element 31. Further, the lid member 21 is formed with a recess 21 c in which the buzzer 36 is disposed so as to be slightly recessed in a direction away from the circuit board 20. The recess 21c is formed by press molding. The upper surface of the buzzer 36 is fixed to the lower surface of the substrate support member 29 on which the circuit board 20 is supported by a ring-shaped double-sided tape 50. On the lower surface of the buzzer 36, a ring-shaped buzzer cushion 51 that contacts the recess 21c of the lid member 21 is attached. Heat dissipation sheets 37a and 37b are attached to the drive element 31 and the diode 35, respectively, in order to improve the heat dissipation performance.

  The window member 22 is a member that is disposed on the mounting portion 24 i and covers the second opening 24 d and the liquid crystal display device 30. The window member 22 has a substantially rectangular shape with rounded corners made of transparent synthetic resin. The window member 22 has a top surface that is slightly curved. Further, the rear side is formed to be thicker than the front side. The window member 22 is mounted on a mounting portion 24i formed to be recessed in the upper surface portion 24b. The window member 22 is fixed to the case member 19 by a double-sided tape 45 having substantially the same outer shape as that of the window member 22 having a waterproof function attached to the placement portion 24i. In this embodiment, the window member 22 is colored except for the portion facing the second opening 24d. The window member 22 and the double-sided tape 45 are formed with through holes 22a and 45a through which the operation portions 42 of the switches SW1 and SW2 can pass, respectively. In the double-sided tape 45, a rectangular opening 45b is formed at a portion facing the second opening 24d.

In the counter case 4 having such a configuration, when the switch operating member 40 of the switch SW1 is mounted on the case member 19, the switch operating member 40 is first mounted on the switch opening 24e from the inside of the case member 19. Then, the seal portion 43c is pushed into the switch wall portion 24g until it comes into contact with the step. In this state, the close contact member 44 is attached to the inner surface of each seal portion 43c, so that the seal portion 43c comes into close contact with the switch wall portion 24g and the switch opening 24e.
In the electric reel having such a configuration, when the fishing line is fed out, the clutch is turned off by pressing the operating member 11 downward, the spool 10 is freely rotated, and the fishing line is fed out by the weight of the weight attached to the fishing line. . When the fishing line is fed out, the spool 10 is rotated, and the water depth display of the liquid crystal display device 30 is changed according to the feeding amount by a detection pulse of a spool rotation sensor (not shown). When the device reaches the shelf, the handle 2 is turned in the line winding direction, the clutch is turned on by a clutch return mechanism (not shown), and the feeding of the fishing line is stopped.

  When the fish hits, the adjustment lever 5 is operated to wind up the fishing line. When the adjusting lever 5 is swung clockwise in FIG. 1, the maximum speed of the spool 10 or the maximum tension acting on the fishing line can be set stepwise according to the swiveling angle.

  As a result, the motor 12 rotates according to the swing angle of the adjustment lever 5. The drive element 31 generates heat in accordance with the load acting at the time of winding, but the air flow generated by the rotation of the spool 10 hits the lid member 21 of the case member 19 and cools the lid member 21. As a result, the driving element 31 disposed in the vicinity of the first bending portion 21a of the lid member 21 and the diode 35 disposed in the vicinity of the second bending portion 21b are easily and reliably cooled.

  Further, since the cylindrical seal portion 43c of the switch operating member 40 is pressed by the contact member 44 to prevent liquid from entering from the switch opening 24e, the seal portion is sandwiched between the circuit board 20 and the case member 19. Compared to the prior art that seals, the counter case 4 can be reliably sealed while suppressing deformation of the circuit board 20.

The light that has entered the reflection unit 28a is bent by the reflection unit 28a, and is diffused and irradiated to the back side of the liquid crystal display device 30 by the irradiation unit 28b. Here, even if the light guide plate 28 is provided with the reflecting portion 28 a and light is emitted from the light emitting element 33 in a direction intersecting the upper surface of the circuit board 20, the light can be diffused and irradiated on the back side of the liquid crystal display device 30. Therefore, even if a gap is formed between the irradiation unit 28 b and the upper surface of the circuit board 20, light can be reliably guided to the back surface of the liquid crystal display device 30. For this reason, a large electric element can be disposed in the gap, and the counter case 4 can be reduced in size.

  (B) It further includes an LCD holder 27 that is mounted on the upper surface of the circuit board 20 and arranges the irradiation portion 28b of the light guide plate 28 and the liquid crystal display device 30 at a distance from the upper surface of the circuit board 20. For this reason, the LCD holder 27 is provided, and the LCD holder 27 is provided with the irradiation portion 28b of the light guide plate 28 and the liquid crystal display device 30 spaced from the upper surface of the circuit board 20. 30 and the irradiation part 28b can be reinforced.

  (C) A control element 32 for controlling the liquid crystal display device 30 is mounted on the upper surface of the circuit board 20 in a gap formed between the circuit board 20 and the irradiation unit 28b. In this case, since the large control element 32 can be disposed in the gap, the counter case 4 can be further downsized.

  (D) The reflective portion 28 a is inclined from the portion facing the light emitting element 33 toward the liquid crystal display device 30 and has a reflective surface 28 c that reflects light toward the liquid crystal display device 30. For this reason, since light is reflected by the inclined reflecting surface 28c, the configuration of the reflecting portion 28a is simplified.

  (E) The fishing reel is an electric reel having a motor for driving the spool 10, and a driving element 31 for driving the motor 12 is mounted on the lower surface of the circuit board 20 opposite to the liquid crystal display device 30. Yes. In this case, since the driving element 31 that is a large electric element and generates heat is mounted on the lower surface of the circuit board 20 apart from the liquid crystal display device 30, the influence of the heat generation is reduced while reducing the size of the counter case 4. The display device 30 is difficult to receive.

<Other embodiments>
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of invention.

  (A) In the above embodiment, the light guide plate 28 and the liquid crystal display device 30 are placed on the LCD holder, but the present invention is not limited to this. For example, the liquid crystal display device 30 and the light guide plate 28 may be fixed to the case member 19 without providing an LCD holder so as to leave a gap. However, if the backlight 23 and the liquid crystal display device 30 are arranged and fixed to the LCD holder 27 mounted on the circuit board 20, they can be assembled together and the assembly cost can be reduced.

  (B) In the above embodiment, the electric reel is exemplified as the fishing reel. However, the fishing reel may be a manually wound double-bearing reel with a counter case.
