  The operation member of Patent Document 1 changes the output of the pressure sensor according to the strength of the pressing force, and changes the spool winding speed according to the output, but in order to maintain the speed, the operation member is continuously pressed. There is a need. On the other hand, the speed adjustment switch of Patent Document 2 can maintain the rotation speed of the motor increased or decreased by operating the switch as it is. However, since the rotation speed of the motor changes according to the operation time of the switch, And it is difficult to easily obtain the desired speed.

  An object of the present invention is to enable quick and easy adjustment of motor output in a motor control device for an electric reel.

  An electric reel motor control device according to an aspect of the present invention is an electric reel motor control device that drives a spool rotatably mounted on a reel body with a motor, and includes a first pressing operation unit and a second pressing operation. And a motor control means. The first pressing operation unit and the second pressing operation unit have a pressure sensor that is provided in the reel body and whose output changes according to the pressing force. The motor control means has an output increasing means, an output decreasing means, and an output maintaining means, and controls the motor output of the motor according to the output of the pressure sensor. The output increasing means increases the motor output according to the output of the pressure sensor when the first pressing operation unit is pressed. The output decreasing means decreases the motor output according to the output of the pressure sensor when the second pressing operation unit is pressed. The output maintaining means maintains the motor output when the pressing is stopped when the pressing of the first pressing operation unit or the second pressing operation unit is stopped.

  In the electric reel motor control apparatus, pressure sensors are provided on two pressing members of the first pressing operation unit and the second pressing operation unit, respectively. Then, by changing the output of the pressure sensor by the pressing force, the motor output increases or decreases according to the pressing force. Furthermore, when the pressing of the first pressing operation unit or the second pressing operation unit is stopped, the motor output when the pressing is stopped is maintained. Thereby, when it is desired to maintain a constant motor output, it is not necessary to continue pressing the pressing operation portion, and the motor output can be adjusted quickly and easily by simply changing the pressing force.

  Preferably, the motor output is the rotational speed of the motor, and the output increasing means and the output decreasing means increase or decrease the motor rotational speed greatly as the pressing force increases. In this case, if the angler strongly presses the pressing operation part, the motor rotation speed increases or decreases greatly, so that the angle of the angler and the motor rotation speed match, making it easier to adjust the motor output. Become.

  Preferably, the motor output is a motor torque, and the output increase means and the output decrease means increase or decrease the motor torque greatly as the pressing force increases. In this case, if the angler strongly presses the pressing operation portion, the motor torque greatly increases or decreases greatly. Therefore, the angle of the angler and the motor torque are matched, so that the motor output can be adjusted more easily.

  Preferably, the 1st press operation part and the 2nd press operation part are provided in the upper surface or side surface of the reel main body. Thereby, even in the state where the electric reel is gripped, the pressing operation portion can be pressed with the fingertip of the gripping hand, so that the operability is improved.

Moreover, the 1st press operation part 11 and the 2nd press operation part 12 are arrange | positioned adjacent to each other.

  As shown in FIG. 2, the first and second pressing operation units 11 and 12 have pressure sensors 11a and 12a, respectively. The pressure sensors 11a and 12a are members that output an electric signal at a level corresponding to a force (hereinafter referred to as a pressing force) that presses the first and second pressing operation portions 11 and 12, and the magnitude of the pressing force. The corresponding detection value is output as an electric signal to the motor control unit 16 of the control unit 14 to be described later. The first pressing operation unit 11 increases the output of the motor 8 corresponding to the pressing force (hereinafter referred to as motor output) only while the first pressing operation unit 11 is being pressed (for example, the rotation speed of the motor 8 increases). ) As long as the second pressing operation unit 12 is pressing the second pressing operation unit 12, the motor output corresponding to the pressing force decreases (for example, the rotation speed of the motor 8 decreases).

  The motor drive circuit 19 controls the drive of the motor 8 according to the pressing operation of the first and second pressing operation units 11 and 12.

<Processing flow of motor control unit>
Next, the flow of the motor control process performed by the motor control unit 16 of the control unit 14 when the power supply of the electric reel is on will be described with reference to the flowchart shown in FIG. The motor output here is, for example, the rotational speed of the motor 8. Here, when a load is applied and the rotational speed of the spool 2 decreases, feedback control is performed so as to maintain a predetermined rotational speed.

  First, in step S1, it is determined whether or not the first pressing operation unit 11 has been pressed. If it is determined that the button has been pressed, the process proceeds to step S2.

  In step S2, the motor output (here, the rotational speed of the motor 8) is increased by an output corresponding to the electrical signal output from the pressure sensor 11a of the first pressing operation unit 11.

  Next, in step S3, it is determined whether or not the pressing of the first pressing operation unit 11 is stopped. If not stopped, the rotation speed of the motor 8 is increased by the motor output corresponding to the electrical signal output from the pressure sensor 11a until the pressing is stopped. If it is determined that the pressing is stopped, the process proceeds to step S8, and the motor output when the pressing is stopped is maintained. That is, here, the rotation speed of the motor 8 when the pressing of the first pressing operation unit 11 is stopped is maintained.

  If it is determined in step S1 that the first pressing operation unit 11 is not pressed, the process proceeds to step S4. In step S4, it is determined whether or not the second pressing operation unit 12 has been pressed. If it is determined that the button has been pressed, the process proceeds to step S5. If it is not pressed, the motor control process is not executed.

  Next, in step S5, it is determined whether there is a motor output (here, the rotational speed of the motor 8, that is, whether the motor 8 is rotating). If there is no motor output, the motor control process is not executed. If there is a motor output, the process proceeds to step S6.

  In step S6, the motor output (here, the rotational speed of the motor 8) is decreased by an output corresponding to the electrical signal output from the pressure sensor 12a of the second pressing member 12.

  Next, in step S7, it is determined whether or not the pressing of the second pressing operation unit 12 is stopped. If not stopped, the rotational speed of the motor 8 is reduced by the motor output corresponding to the electrical signal output from the pressure sensor 12a until the pressing is stopped. If it is determined that the pressing is stopped, the process proceeds to step S8, and the motor output when the pressing is stopped is maintained. That is, here, the rotation speed of the motor 8 when the pressing of the second pressing operation unit 12 is stopped is maintained.

  Here, in step S2, the motor control unit 16 increases the motor output (here, the rotational speed of the motor 8) with the motor output corresponding to the electric signal output from the pressure sensor 11a of the first pressing operation unit 11. When this is done, control is performed so that the rotational speed of the motor 8 increases greatly as the pressing force of the first pressing operation section 11 increases. In step S6, when the motor output (here, the rotational speed of the motor 8) is reduced by the motor output corresponding to the electric signal output from the pressure sensor 12a of the second pressing operation unit 12, the second pressing operation is performed. As the pressing force of the portion 12 increases, the rotation speed of the motor 8 is greatly decreased (for example, if the pressure is strongly pressed, the rotation of the motor 8 is stopped instantaneously).

  Thereby, if the angler pushes the 1st or 2nd press operation part 11 and 12 strongly, the rotational speed of the motor 8 will increase or decrease greatly. For this reason, the angle of the angler matches the motor output, and the motor output can be adjusted quickly and easily.

[Second Embodiment]
Next, the flow of motor control processing performed by the motor control unit 16 in the electric reel adopting the second embodiment of the present invention will be described according to the flowchart shown in FIG. The flow of the motor control process of the second embodiment is such that a more precise control process is performed in the motor control process of the first embodiment. Note that description of processing similar to that of the first embodiment is omitted here. Also in the second embodiment, the motor output is, for example, the rotational speed of the motor 8, and here, when a load is applied and the rotational speed of the spool 2 decreases, feedback control is performed so as to maintain a predetermined rotational speed. .

  The motor output is controlled in Nmax + 1 stages from 0 to Nmax. The zero stage is a stop state of the motor 8, and the Nmax stage is a state in which the motor 8 is driven at the maximum output. Here, for example, the motor 8 is controlled by the PWM method, and the maximum output is a duty ratio of 100%.

  Further, here, a lower limit value and an upper limit value (for example, a lower limit value of 30 grams and an upper limit value of 2 kilograms) of the pressing force output from the pressure sensors 11a and 12a are set. Then, the range between the lower limit value and the upper limit value is divided into arbitrary stages (for example, 31 equal parts), and the motor output stage increase number and decrease number corresponding to each stage are set.

  First, in step S21, it is determined whether or not the first pressing operation unit 11 is pressed with a pressing force P1 of 30 g or more. Specifically, for example, by detecting an output from the pressure sensor of the first pressing operation unit 11, it is determined whether or not the first pressing operation unit 11 is pressed with a pressing force P1 of 30 g or more. If only an output with a pressing force P1 of less than 30 g is detected, the output is disregarded as not being pressed to avoid erroneous operation. Here, for example, a resistance film type pressure sensor is used to configure the circuit so that the voltage as an output is proportional to the pressing force.

  When it is determined that the pressing force P1 is 30 g or more, the process proceeds to step S22, and it is determined whether the pressing force P1 is less than 2 kg. When the pressing force is 2 kg or more in step S22, the process proceeds to S31, and the motor output stage N is changed to Nmax. In the next step S29, the motor output is maintained at step Nmax.

  If the first pressing operation unit 11 is pressed with a pressing force P1 of 2 kg or more while the motor output at the stage Nmax is maintained, the process proceeds to step S31. Since the output is maintained, as a result, the motor output continues to be maintained at the motor output stage Nmax.

  When the pressing force P1 is less than 2 kg in step S22, the process proceeds to step S23, and the current motor output stage N is read.

  Next, in step S24, the step increase number M set in advance for the output of the pressure sensor 11a is read from the memory, and the process proceeds to step S25.

  In step S25, it is determined whether the current motor output stage N plus the stage increase number M is less than Nmax. When it is less than Nmax, the process proceeds to step S26, and N + M is set as a new motor output stage. Specifically, for example, when the first pressing operation unit 11 is pressed with a pressing force P1 of 300 g to 400 g in the motor output state in the motor output stage 5, it is set in advance corresponding to the range of the pressing force P1. Add a step increment of 2 and set the motor output stage to 7. Thereafter, the process proceeds to step S27.

  If it is determined in step S25 that the current motor output stage N plus the stage increase number M is equal to or greater than Nmax, the process proceeds to step S30, and the motor output stage is set to Nmax-1 which is one stage lower. That is, the motor output stage does not become Nmax unless the pressing force P1 to the first pressing operation unit 11 exceeds 2 Kg. Thereafter, the process proceeds to step S27.

  In step S27, for example, after waiting for 0.5 seconds, the process proceeds to step S28.

  In step S28, as in step S21, it is determined whether or not the first pressing operation unit 11 has been pressed with a pressing force P1 of 30 g or more. That is, here, it is determined whether or not the first pressing operation unit 11 is continuously pressed with a pressing force P1 of 30 g or more. If it is pressed with a pressing force P1 of 30 g or more, the process returns to step S22. If it is not pressed with the pressing force P1 of 30 g or more, the process proceeds to step S29, and the motor output is maintained at the motor output stage set in step S26 or step S30.

  If it is determined in step S21 that the first pressing operation unit 11 is not pressed with the pressing force P1 of 30 g or more, the process proceeds to step S32.

  In step S32, it is determined whether or not the second pressing operation unit 12 is pressed with a pressing force P2 of 30 g or more based on an output from the pressure sensor 12a. If only an output with a pressing force P2 of less than 30 g is detected, the output is disregarded as not being pressed to avoid erroneous operation.

  When it is determined that the pressing force P2 is 30 g or more, the process proceeds to step S33, and it is determined whether or not the motor output stage N is 1 or more, that is, whether the motor is driven. If the motor output stage N is 0, the operation of the second pressing operation unit 12 for decreasing the output is meaningless, and the motor control process is not executed. If the motor output stage N is 1 or more, the process proceeds to step S34.

  In step S34, it is determined whether or not the pressing force P2 is less than 2 kg. When the pressing force P2 is 2 kg or more, the process proceeds to step S42, and the current motor output stage N is changed to zero. That is, the drive of the motor 8 is stopped.

  When the pressing force P2 is less than 2 kg in step S34, the process proceeds to step S35, and the current motor output stage N is read.

  Next, in step S36, the step reduction number L preset for the output of the pressure sensor 12a is read from the memory, and the process proceeds to step S37.

  In step S37, it is determined whether or not the value obtained by subtracting the step reduction number L from the current motor output stage N is 1 or more. If it is 1 or more, the process proceeds to step S38, NL is set as a new motor output stage, and the process proceeds to step S39. If NL is less than 1, the process proceeds to step S41, the motor output stage is set to 1, and the process proceeds to step S39.

  In step S39, for example, after waiting for 0.5 seconds, the process proceeds to step S40.

  In step S40, as in step S32, it is determined whether or not the second pressing operation unit 12 has been pressed with a pressing force P2 of 30 g or more. That is, here, it is determined whether or not the second pressing operation unit 12 is continuously pressed with a pressing force P2 of 30 g or more. If it is pressed with a pressing force P2 of 30 g or more, the process returns to step S34. If it is not pressed with the pressing force P2 of 30 g or more, the process proceeds to S29, and the motor output is maintained at the motor output stage set in step S38 or step S41.

<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.

However, the current supplied to the motor 8 is controlled so that the hoisting torque becomes a predetermined value. Good. At this time, for example, if the angler strongly presses the first or second pressing operation unit 11, 12, the torque of the motor 8 is controlled so as to increase or decrease greatly. The motor output can be adjusted quickly and easily while matching. Alternatively, the spool diameter of the spool 2 may be calculated and controlled so that the tension becomes a predetermined value.

  (C) The control method for rotating the motor 8 in accordance with the electrical signals output from the pressure sensors 11a and 12a in the above embodiment is controlled at a predetermined spool rotation speed or at a predetermined torque value. It may be possible to select any of the two options.

That is, the angler may arbitrarily set the threshold of the pressing force. At this time, when the motor 8 is in a stopped state and the first and second pressing operation portions 11 and 12 are operated with a pressing force equal to or higher than a predetermined value, the mode may be shifted to a pressing force setting mode for setting a pressing force threshold. .
