Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing reel including a microprocessor that outputs a length of a fishing line fed from a spool to a display device.

[Conventional technology]

Conventionally, examples of the reel configured as described above include a so-called electric reel that winds a fishing line by the power of an electric motor, or a reel that winds a fishing line manually. The reel also has a microprocessor for processing a measurement signal from a sensor for measuring the amount of rotation of the spool or the like, and outputting a feed amount of the fishing line to a display device such as a liquid crystal type as a digital number.

[Problems to be Solved by the Invention] Considering the operation of the microprocessor, since this type of microprocessor operates at a low control voltage of about several volts, it is necessary to consider a case where static electricity acts from the outside during operation. The data value in the register of the microprocessor changes, so-called data garbled,
Runaway may occur due to such phenomena.

Also, when runaway occurs in the microprocessor in this way, it is almost impossible to determine whether or not the runaway is caused by the liquid crystal display alone, and the runaway of the fishing line is relied on the value displayed on the liquid crystal display due to the runaway. If you go, even if the winding of the device is completed, the displayed value may indicate the remaining amount of fishing line.In such a runaway situation, the winding is maintained, and as a result, the tip of the fishing rod There is room for improvement because it may break.

SUMMARY OF THE INVENTION An object of the present invention is to rationally configure a reel capable of surely allowing an angler to recognize a runaway state even when a runaway occurs in the microprocessor.

[Means for solving the problem]

As described at the beginning, a feature of the present invention is that, in a fishing reel including a display device and a microprocessor, the control operation is stopped by a reset signal being input to a reset terminal of the microprocessor, and Setting the operation of the microprocessor so as to output a predetermined state to the display device, and outputting an intermittent pulse signal in a loop of a control program set in the microprocessor each time the processing of this loop is performed. The pulse generating means is interposed, and when the output of the intermittent pulse signal from the pulse generating means is stopped,
A reset circuit for outputting a reset signal to the reset terminal is provided. The operation and effect are as follows.

[Action]

When the features of the present invention are configured as shown in FIGS. 1 to 5, for example, the control program is repeatedly processed under the condition that the microprocessor (15) is operating normally. (P) outputs an intermittent pulse signal, and if a runaway occurs in the microprocessor (15), processing outside the control program is performed. No signal is output, and the reset circuit (R) outputs a reset signal to the reset terminal (33). As a result, the control operation of the microprocessor (15) is stopped, and the resetting is performed on the display device (12). A predetermined state indicating that the operation has been performed is output.

That is, according to the present invention, when a runaway occurs in the microprocessor (15), the runaway is detected by hardware (reset circuit (R)) external to the microprocessor (15) and resetting is performed. The reliability is extremely high as compared with the case where the reset is performed by software, and the angler can easily recognize that the reset has been performed by the display contents of the display device (12).

[Effects of the Invention] Therefore, even if a runaway occurs in the microprocessor, the reeler that is unlikely to cause inconvenience such as breaking or damaging the tip of the fishing rod can be rationally recognized by making the angler surely recognize the runaway state. It was composed.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 to 5, a thread guide tool reciprocating left and right along a guide punch (3) by driving a screw shaft (2) between left and right side cases (1) and (1). (4) Spool (6) for winding fishing line (5), thumb rest (7)
While arranging each, the left and right side cases (1),
A control case (8) is provided between the upper parts of (1), and a drag reel (9), a handle (10), and a clutch lever (11) are provided on a right side case (1), and a fishing reel is provided. Constitute.

The control case (8) includes a liquid crystal display (12) as a display device, a reset switch (13), and a set switch (14).
5), an alarm (16), a memory (17), a pair of reed switches (18) and (18) are installed, and the left side case (1) is embedded in the side of the spool (6). A pair of reed switches (20), (20) operated by a plurality of magnets (19) inserted therein are provided.

In this reel, the length of the fishing line (5) fed from the spool (6) based on only the rotation of the spool (6) when fishing is output to the liquid crystal display (12) as digital numbers ( Hereinafter, this operation is referred to as a display operation. In order to make the output value accurate, a new fishing line (5) is wound around the spool (6) (hereinafter referred to as a learning operation). To do so, a tool (T) is used as shown in FIG.

That is, the tool (T) is fixed to the control case (8) by the clamp (21) with the tool body (22).
And a swing arm (24) supported swingably around a support shaft (23) with respect to the tool body (22).
A power transmission system that transmits the power from the roller (25) at the end of the swing arm (24) to the wheel (27) having the magnet (19) via a plurality of gears (26) is installed. 5, the winding operation is performed by the handle (10) while maintaining the roller (25) in contact with the outer surface of the fishing line (5) wound on the spool (6) as shown in FIG. Thus, the reed switch (18) of the control case (8),
(18) measures the amount of rotation of the roller (25) based on the action of the magnet (19) of the wheel (27), and at the same time, the reed switches (20) and (20) of the side case (1) use the spool (6). The amount of rotation of the spool (6) is measured based on the action of the magnet (19), and the operation of storing various relative data in the memory (17) is performed.

By the way, at the start of this learning operation, the reset switch (13) is turned ON, and at the end, the set switch (14) is turned on.
Turn ON (this control operation is not described in detail).

When the learning operation is completed, the display operation can be performed based on only the rotation of the spool (6) with the tool (T) removed.

The configuration described above is no different from the conventional reel, and in the present invention, when the microprocessor (15) detects that the microprocessor (15) runs away during the display operation, the processor (15) is controlled. A reset circuit (R) for resetting is provided.

That is, the outline of the control program for the display operation set in the processor (15) is shown in FIG. 3, and in this program, the reed switches (20), (2
0), the counting operation is performed together with the discrimination of the rotation direction, and the length of the fishing line (5) is output to the display (12) based on the count value (# 1 to # 1).
In addition to the basic operation (# 3 step), a routine (# 4 step) for generating a pulse for outputting an intermittent pulse signal is interposed in the control pool, and when the reset switch (13) is turned ON, After a predetermined pattern or the like is displayed on the display (12), an operation of stopping the display operation (Steps # 5 to # 7) is set.

When the reset switch (13) is turned ON, the processor (15) is reset by a hardware interrupt, and then the above-described steps # 6 and # 7 are executed.

Step # 4 described above is an embodiment of the pulse generation means (P). When step # 4 is executed normally,
An intermittent pulse signal is output from the output terminal (28) of the processor (15), and this signal intermittently turns on and off the transistor (29) of the reset circuit (R).
0) is intermittently discharged and the input terminal of the NAND gate (31) is maintained at the “Lo” level. As a result, the output terminal of the other NAND gate (31) is maintained at the “Lo” level. If a runaway occurs in the display operation, the above-described # 4 step is not executed, so that the intermittent pulse signal is not output from the output terminal (28) of the processor (15), and the transistor (29) remains OFF. And the capacitor (3
0), the input terminal of the NAND gate (31) is set to “H”.
As a result of switching to the "i" level, the output terminal of the other NAND gate (31) is switched to the "Hi" level, so that a "Hi" level signal as a reset signal is input to the reset terminal (33) which is conductive with this output terminal. As described above, a predetermined pattern is output to the display (12),
The processor (15) is made to recognize that a runaway has occurred.

When a reset signal is input to the reset terminal (33), the display operation is forcibly stopped by a hardware interrupt in the same manner as when the reset switch (13) is turned ON.

By the way, in this control system, a power supply circuit with a battery (34)
Is configured to be supplied with power.
