Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a runner watch, and more particularly to a runner watch that displays information for the runner to determine an appropriate pace.

[0002]

2. Description of the Related Art As electronic timepieces have become more multifunctional, wristwatches have been devised which can display temperature and humidity in addition to a stopwatch function. With such a wristwatch, since the current environment can be grasped, the runner can judge whether the pace should be slowed down or raised. Also,
By using the stopwatch function, the runner can check the split time and lap time each time the vehicle passes a predetermined section, so that the pace distribution can be corrected in the future.

[0003]

However, it is difficult to use a wristwatch, which has a stopwatch function and a temperature / humidity display function, as in the prior art, because it is not specially designed for a runner. There is a problem.

First, the runner cannot judge whether the pace should be slowed down or raised by simply displaying the temperature and humidity as numerical values as in the conventional wristwatch. This is because the pace distribution is of a nature that should be set by looking at both temperature and humidity. Therefore, a method of obtaining the discomfort index from the temperature and humidity and displaying the discomfort index is also conceivable, but it is not possible to determine how fast the runner should run just by looking at the index.

Further, in the conventional wristwatch, even if both the split time and the lap time are displayed, the runner does not have enough room to look into the display, so it is not easy to determine which is the split time or the lap time. Therefore, there is a method of displaying one of them conspicuously, but if such a display method is adopted, it becomes difficult to see the time on the other side.

Further, since the body temperature rises during running, the conventional wristwatch has a measure to prevent the influence of the body temperature even though the body temperature has a great influence on the measurement results of temperature and humidity. Absent. Therefore, the reliability such as the temperature displayed during running is low.

In view of the above problems, the object of the present invention is to
It is to provide a runner's wristwatch that can easily convey information for determining an appropriate pace even if the runner has no room.

Another object of the present invention is to provide a wristwatch for a runner in which the body temperature does not affect the display contents of temperature and humidity.

[0009]

In order to solve the above problems, in a runner wristwatch according to a first embodiment of the present invention, a case to which an arm wearing band is connected, and a time measuring means for measuring time. , A temperature sensor for measuring temperature,
A humidity sensor for measuring humidity, a rank data storage section that stores running environment rank data that ranks the environment suitable for running according to temperature and humidity, and measurement of temperature sensor and humidity sensor Based on the result, a display control means for displaying the current running environment rank obtained from the rank data storage unit together with the current temperature and humidity in a predetermined area of the display unit formed on the case surface is provided. Have.

In the runner's wristwatch according to the second aspect of the present invention, the case to which the wristband is connected, the timekeeping means for measuring the time, and the splittime based on the external operation of the timekeeping means. A midway time measuring means for measuring the lap time, a split time and a lap time measured by the midway time measuring means, a first midway time display area of a display unit formed on the surface of the case, and a display form different from this display area. Display control means for displaying in the second midway time display area,
Based on the external operation, the first intermediate time display area and the second intermediate time display area
It is characterized in that display content exchanging means for exchanging the displayed intermediate time with the intermediate time display area is provided. In the present invention, as a method of making the display forms different between the first midway time display area and the second midway time display area, for example, there is a method of changing the display size. In the present invention, further, a temperature sensor for measuring temperature, a humidity sensor for measuring humidity, and running environment rank data in which whether or not the environment is suitable for running in correspondence with temperature and humidity is stored. The display control means displays the current running environment rank obtained from the rank data storage unit together with the current temperature and humidity based on the measurement results of the temperature sensor and the humidity sensor. It is preferable to display it in a predetermined area.

Further, according to the present invention, the runner wristwatch is removed from the wrist based on an input section for inputting whether or not the runner wristwatch is worn on the arm, and an input result from the input section. When it is determined that
The temperature and humidity measured by the temperature sensor and the humidity sensor are displayed on the display control means as they are, and when it is determined that the runner's wristwatch is worn on the wrist, the temperature and humidity measured by the temperature sensor and the humidity sensor are By providing the temperature / humidity correction means for displaying the result of correcting the influence of body temperature on the display control means, it is possible to realize a runner's wristwatch in which the display contents of temperature and humidity are not influenced by body temperature.

In the present invention, while enhancing the feeling of wearing on the arm,
From the viewpoint of improving the measurement accuracy of the temperature sensor and the humidity sensor, it is preferable that the case has a dimension in the vertical direction to which the wristband is coupled that is shorter than a dimension in the horizontal direction.

[0013]

In the runner wristwatch according to the first aspect of the present invention, not only the temperature and humidity are displayed, but also whether or not the environment is suitable for running is displayed as a running environment rank. Therefore, the runner can easily determine whether the current environment is good or bad as a rank even if he / she does not have enough room during the running, and thus can determine an appropriate pace suitable for the environment.

In the runner wristwatch according to the second aspect of the present invention, the split time and the lap time can be displayed in the first and second midway time display areas having different display modes, and the display area between the split time and the lap time can be displayed. Can be replaced. Therefore, the runner can display the split time in the display area on the easy-to-see side and then display the lap time there, so that both the split time and the lap time can be easily grasped even if there is no room during running. . Therefore, the runner can determine the proper pace.

In the present invention, when it is inputted from the input section whether or not the runner's wristwatch is worn on the wrist,
Based on this input result, when it is determined that the body is removed from the arm, the temperature / humidity correction means displays the measurement results of the temperature sensor and the humidity sensor as they are on the display control means, assuming that there is no effect of body temperature. Let On the other hand, when it is determined that the device is worn on the arm, the temperature / humidity correction unit corrects the influence of body temperature on the measurement results of the temperature sensor and the humidity sensor, and the corrected result is displayed by the display control unit. To display. Therefore, in the wrist-worn temperature / humidity device according to the present invention, the error caused by the influence of the body temperature can be removed, and the displayed temperature and humidity are accurate.

[0016]

An embodiment of the present invention will be described with reference to the drawings.

[Overall Structure] FIG. 1 is an enlarged plan view showing a main part of a runner's wristwatch according to the present embodiment, and FIG. 2 is a- of FIG.
It is sectional drawing in the a'line.

Referring to FIG. 1, a runner wristwatch 1 of this example is shown.
Is composed of a device main body 2 having a substantially rectangular planar shape of 31.5 mm × 29.0 mm, and arm mounting bands 4 connected to both sides thereof. The device body 2 is a case 2 made of various materials such as plastic and metal.
The case 20 has a rectangular window for forming the display unit 10 in a region slightly deviated in the 9 o'clock direction of the wristwatch. In the case 20, a vertical dimension (12 in a wristwatch) to which the wrist band 4 is connected.
The dimension in the hour-6 o'clock direction is shorter than the dimension in the lateral direction (the dimension in the wristwatch in the 3 o'clock-9 o'clock direction). For this reason, the runner's wristwatch 1 has an improved fit on the wrist.

Further, the wristwatch 1 for the runner has a device body 2
Five buttons 80, 81, 82, 8 on and around the
3 and 84 are provided, and these buttons 80 to 84 are provided.
By doing so, various functions to be described later are exhibited.

The display section 10 will be described later in detail with respect to the contents displayed therein.
It is composed of a liquid crystal display panel 5 including 14 and 16. Since the case 20 is horizontally long, the liquid crystal display panel 5 is a wide-angle panel. Further, the liquid crystal display panel 5 is provided with an EL backlight function.

The runner wristwatch 1 has a clock function as well as a normal watch and a stopwatch, and in the state shown in FIG. 1, the display section 10 displays August 25 in the upper display area 12. The message that it is Monday and that it is Monday is displayed. In the lower display area 16, the current time is 10:00 am
It is displayed that it is 8 minutes and 59 seconds. Here, the display in the display area 16 in the lower stage is performed by a large segment having a vertical dimension of about 4.7 mm, which is similar to a normal stopwatch. The middle display area 14 is further divided into upper and lower two areas, and in the lower display area 144, the temperature is 24.8 ° C. and the relative humidity is 57% R.
It is displayed that it is H. In addition, in the upper display area 142 of the middle display area 14, whether or not the current environment is easy to run is displayed in the ranks A to E based on the temperature and the relative humidity. ing.

[Arrangement Structure of Temperature Sensor] In the runner wristwatch 1 of this example, since the case 20 is horizontally long, the temperature sensor 30 covered with the temperature sensitive cap 32 and the pressing plate are provided on the 3 o'clock side of the wristwatch. The humidity sensor 40 fixed by 42 is arranged. In this way, the horizontally long case 2
If 0 is used and the temperature sensor 30 and the humidity sensor 40 are arranged on the side of the 3 o'clock direction, the sleeve of the user's clothes will be on the side of the 3 o'clock direction even when the wristwatch 1 for a runner is worn on the arm. There is no cover. Further, the side in the 3 o'clock direction is in a state of slightly floating from the arm even when the runner's wristwatch 1 is worn on the arm, so that the detection result by the sensor is less likely to be affected by the body temperature. Therefore, there is an advantage that highly accurate measurement can be performed.

The measuring range of the temperature sensor 30 is -1.
The temperature is 0 ° C to 50 ° C, and the unit of measurement is 0.1 ° C. The measurement range of the humidity sensor 40 is 20% RH to 80%
RH, and the unit of measurement is 1% RH.

As shown in FIG. 2, the case 20 is composed of a body portion 22 corresponding to the main body portion thereof and a back cover 24 attached to the back side thereof, and the front side of the case 20 is a temperature sensor arrangement space. It is fifty. Here, the temperature sensor arrangement space 50 is formed outside the case 20. The case 20 is covered with a protective plate 26 on its front surface side. A hole 262 for allowing outside air to flow in and out is formed in a region of the protective plate 26 corresponding to the temperature sensor arrangement space 50. Also, the hole 26
The lower surface side of the area where 2 is formed is covered with a shield plate 56 for electrostatic shielding. Also on this shield plate 56,
A large number of holes 562 are formed corresponding to the formation region of the holes 262. Therefore, in the temperature sensor arrangement space 50, the hole 262 of the protective plate 26 and the shield plate 5 for electrostatic shielding are provided.
Outside air can enter and exit through the holes 562 of No. 6. In addition,
The shield plate 56 constitutes one side surface portion of the temperature sensor arrangement space 50.

In the temperature sensor arrangement space 50, the temperature sensor 30 covered with the temperature sensitive cap 32 is arranged.
The temperature-sensitive cap 32 includes a base portion 322 having a hollow inside and a thin tip portion 324 extending from there to the tip side. Inside the base portion 322 of the temperature-sensitive cap 32, the thermistor 34 (heat-sensitive portion of the temperature sensor 30) is provided at the innermost portion.
Is arranged. The lead wire 36 drawn out from the base portion 342 of the thermistor 34 passes through the lead wire lead-out passage 28 that is partially projected from the case 20 and is arranged at another position inside the case 20 (see FIG. 2). (Not shown). Thermistor 3
4 is the sealant 3 inside the base 322 of the temperature sensitive cap 32.
Protected by 8. The thermistor 34 is
It is preferable that the temperature-sensitive cap 32 is fixed with the sealant 38 in a state of being in contact with the innermost part of the base 322 of the temperature-sensitive cap 32.

The temperature sensor 30 is the temperature sensor arrangement space 5
At 0, it is arranged laterally so as to float from the bottom portion 521. That is, the shield plate 56 has a recess 564 formed in a portion that constitutes a side surface of the temperature sensor arrangement space 50. In the recess 564, the tip end 324 of the temperature-sensitive cap 32 is provided with the insulating cap 326.
Is fitted through. Here, instead of the recess 564, a hole is formed, and the tip 32 of the temperature-sensitive cap 32 is formed therein.
4 may be fitted via an insulating cap 326. On the other hand, the base portion 322 of the temperature-sensitive cap 32 is fitted to the open end of the lead wire drawing passage 28 (the other side surface portion of the temperature sensor arrangement space 50) via the packing 328. Therefore, the portion of the temperature sensor 30 where the thermistor 34 is located is not in contact with any portion of the inner surface portion of the temperature sensor arrangement space 50.

As described above, in the runner wristwatch 1 of the present example, as shown in FIG. 3 in which the surroundings of the temperature sensor 30 are enlarged and schematically shown, the portion of the temperature sensor 30 where the thermistor 34 is located is the case 20. It is in a protruding state. Therefore, even when the runner's wristwatch 1 is worn on the wrist, the body temperature is not directly transmitted to the portion of the temperature sensor 30 where the thermistor 34 is located, even if it is transmitted to the case 20. Also,
It is conceivable that the body temperature is transmitted from the back cover 24 to the entire air inside the case 20 and is transmitted to the mounting portion of the temperature sensor 30 via the lead wire lead-out passage 28, but in the present example, the lead wire lead-out passage 28 is narrow and The distance to the temperature sensor 30 is long. Moreover, the temperature sensitive cap 32 is sealed with the sealant 38.
Since it is fixed at, the body temperature hardly reaches the thermistor 34. Therefore, the temperature sensor 30
Detects temperature without being affected by body temperature even when the wristwatch 1 for a runner is worn on the wrist.

Further, since the temperature sensor 30 is separated from the bottom portion 521 of the temperature sensor arrangement space 50 by a predetermined gap, the outside air entering the temperature sensor arrangement space 50 is, as indicated by an arrow A, a temperature sensor. The temperature sensor 30 smoothly flows around the gap between the bottom portion 521 and the bottom portion 521. Therefore, since the temperature sensor 30 is constantly in contact with fresh outside air, the temperature sensor 30 responds quickly to changes in the outside air temperature.

For example, in FIG. 4, the temperature sensor 30 is floated as in this example and the temperature sensor is arranged inside the case. The change in the detection result of the temperature sensor when the temperature sensor is placed in an environment of 0 ° C. is shown in comparison. In FIG. 4, the change in temperature measured by the runner wristwatch 1 of this example is shown by a solid line L1, and the change in temperature when the temperature sensor is arranged inside the case is shown by a solid line L2. As can be seen from this figure, in the runner wristwatch 1 of this example, the temperature drops to about 5 ° C in about 5 minutes after being placed in an environment of 0 ° C, whereas the temperature sensor is arranged inside the case. In this case, the measured value does not decrease to about 10 ° C. or lower even after 15 minutes.

[Arrangement Structure of Humidity Sensor] Referring to FIG. 2 again, the space defined by the body portion 22 and the back lid 24 in the inside of the case 2 serves as a humidity sensor attachment portion 54. In the humidity sensor mounting portion 54, the humidity sensor 40 is arranged with the moisture sensitive surface facing upward. On the upper surface of the humidity sensor mounting portion 54, a passage 541 is formed for the body portion 22. On the other hand, the temperature sensor arrangement space 5
The bottom surface portion 521 of 0 is composed of a pressing plate 42 fixed to the body portion 22 with two pressing screws 421 and 422. A large number of small holes 424 are formed in the pressing plate 42 at positions corresponding to the passages 541. The humidity sensor attachment portion 54 and the temperature sensor arrangement space 50 are separated from each other through the passages 541 and the holes 424. It is possible to communicate.

Here, a tetrafluoroethylene fiber film 44 having a film thickness of several tens of μm and fixed by a pressing plate 42 is interposed between the humidity sensor mounting portion 54 and the temperature sensor arrangement space 50. Since the tetrafluoroethylene fiber membrane 44 has air permeability, the temperature sensor arrangement space 50 is in communication with the humidity sensor attachment portion 54.

Further, since the tetrafluoroethylene fiber film 44 is also water repellent, water does not enter the humidity sensor mounting portion 54 from the temperature sensor arrangement space 50. Therefore, the life waterproofing performance that can withstand going out on a rainy day while the runner's wristwatch 1 is worn on the wrist is sufficiently ensured. Further, since the passage 541 is configured as a plurality of small holes 402 that can communicate with the hole 424, the passage 5
The peripheral portion of 41 has a function of guiding the outside air that has passed through the tetrafluoroethylene fiber membrane 44 to the humidity sensor 40 and a function of preventing the deformation due to the external pressure while ensuring the air permeability of the tetrafluoroethylene fiber membrane 44. It also has a function as a reinforcing part. Therefore, as compared with an electronic device using the tetrafluoroethylene fiber membrane 44 as it is, it is superior in pressure resistance performance.
Instead of the passage 541 in which the hole 402 is formed, for example, a backup plate in which slits or holes are formed is arranged on the back surface of the tetrafluoroethylene fiber membrane 44 as a reinforcing portion,
The pressure resistance of the tetrafluoroethylene fiber membrane 44 may be improved. Further, as the tetrafluoroethylene fiber membrane 44, a sheet made of itself or one obtained by stacking non-woven fabrics to increase strength may be used.

Also, around the passage 541, the packing 4
Since 42 is fixed to the body portion 22 by the holding plate 42, even if water enters from the mounting portions of the holding screws 421, 422, the water is blocked by the packing 442, so that the water is blocked by the vicinity of the passage 541. Do not invade.

A packing 49 is also attached between the humidity sensor 40 and the body portion 22. A spacer 46 having elasticity is provided between the humidity sensor 40 and the back cover 24.
Is inserted in the spacer 46.
Pushing 0 upwards. Therefore, the effect of the packing 49 is exerted on the passage 541 so that the outside air guided to the moisture-sensitive surface of the humidity sensor 40 does not enter the other parts of the case 20. The humidity sensor 4
The lead wire 48 from 0 is also wired up to a display control unit (not shown in FIG. 2) formed at another position inside the case 20.

As described above, in the arrangement structure of the humidity sensor 40 of this example, the humidity sensor 40 has the temperature sensor arrangement space 50 through the tetrafluoroethylene fiber membrane 44 having air permeability.
Since it is in contact with (outside air), the contact between the outside air and the humidity sensor 40 is secured. Even in this state, since the tetrafluoroethylene fiber film 44 has water repellency, the waterproof performance can be secured. The tetrafluoroethylene fiber membrane 44 is fixed by the pressing plate 44, and the small holes 4
24 is provided to ensure air permeability, while the tetrafluoroethylene fiber membrane 44 is supported from the back side by the peripheral portion (reinforcing portion) of the passage 541. Therefore, the wristwatch 1 for runners of this example is
It has a high waterproof performance such that it can be swim while wearing it on the arm, for example, a waterproof performance of about 10 atm, and its reliability is extremely high. Moreover, the tetrafluoroethylene fiber membrane 44 is
It also has the advantage of high durability.

[Structure of Display Control Unit] The structure of the display control unit will be described with reference to FIG. FIG. 5 is a block diagram of the periphery of the display control unit for displaying temperature, humidity, date and time, etc. in the runner wristwatch of this example.

In the figure, the display control unit 100 is a CPU
The circuit is configured around 101, and other circuit parts are connected to this. In addition, the display control unit 100 is
It may be configured as a chip microcomputer. C
The PU 101 sends a control signal to each circuit unit to control them and processes the sent data.
First, the oscillating circuit 102 continues to output a clock signal having a constant frequency, and the frequency dividing circuit 103 causes the oscillating circuit 102 to
The signal from is divided to a predetermined frequency. The clock circuit 104 counts the signal from the frequency dividing circuit 103 to obtain the current time, and outputs it to the CPU 101. RA
The M106 sequentially stores data and the like output from the M106 while being controlled by the CPU 101, and
The stored data and the like are output to the CPU 101 based on a command from the CPU 101. Liquid crystal display panel 5
Is driven by the display drive circuit 111, and the CPU 10
Display the data output from 1. The notification sound generator 113 generates a notification sound when an operation is performed from the outside or at a predetermined timing.

Therefore, in the runner's wristwatch 1, as shown in FIG. 1, the display section 10 composed of the liquid crystal display panel 5 is used.
In, the date can be displayed in the upper display area 12 and the time can be displayed in the lower display area 16.

[Temperature / Humidity Display / Correction Function] Referring again to FIG. 5, the temperature sensor 30 measures the temperature and outputs the result to the A / D conversion circuit 130 as an analog signal. The A / D conversion circuit 130 converts the analog signal input from the temperature sensor 30 into a digital signal and outputs CP.
It is output to U101. Therefore, the CPU 101 can calculate the temperature displayed on the liquid crystal display panel 5 by performing a predetermined calculation on the detection result of the temperature sensor 30, and can display the calculated temperature on the liquid crystal display panel 5.

The humidity sensor 40 measures the humidity,
The result is output to the A / D conversion circuit 140 as an analog signal. The A / D conversion circuit 140 includes the humidity sensor 4
The analog signal input from 0 is converted into a digital signal and output to the CPU 101. Here, the humidity sensor 4
Since 0 outputs a signal corresponding to a change in the resistance value of the humidity sensitive element that it has, to obtain the relative humidity,
It is necessary to calculate using the detection result of the humidity sensor 40 and the temperature coefficient at the current temperature. Therefore, the display control unit 100 is provided with a ROM 107.
In 7, a temperature coefficient for each temperature used for calculating the humidity is stored as a table. Therefore, the CPU 101 can obtain the relative humidity based on the detection result of the humidity sensor 40 and the temperature coefficient corresponding to the current temperature obtained from the ROM 107, and display the obtained relative humidity on the liquid crystal display panel 5.

Furthermore, in the runner wristwatch 1 of this example,
As described with reference to FIGS. 2 to 4, since the temperature detection result is configured so as not to be affected by body temperature,
Although there is no practical problem even if the temperature measured by the temperature sensor 30 is displayed as it is, in this example, when the wristwatch 1 for a runner is worn on the wrist for the purpose of further improving the accuracy of the displayed temperature and humidity. The process for displaying the temperature and the humidity is changed from that when the arm is removed from the arm, as described below.

First, as shown in FIG. 1, a button 83 (input section) is provided on the side surface of the apparatus main body 2. By pushing this button 83, the wristwatch 1 for a runner is mounted on the wrist. It is designed to cyclically enter whether it is in the state of being removed or in the state of being removed. That is, button 8
When 3 is pressed, it is input that it is in the mounted state, and when the button 83 is pressed again thereafter, it is input that it is not mounted, and when the button 83 is pressed, the state that it is mounted is input. Return to the state.

Further, as shown in FIG. 5, the display control unit 10
In 0, a temperature / humidity display correction unit 200 is configured to correct the values displayed as the temperature and the relative humidity only when the runner's wristwatch 1 is worn on the wrist. The temperature / humidity display correction unit 200 detects the temperature measured by the temperature sensor 30 only when the operation performed on the button 83 means that the wristwatch 1 for the runner is worn on the wrist. A calculation unit 201 that performs calculation for correction is configured.

The temperature / humidity display correction unit 200 having such a configuration
The content of the correction performed in is based on the following principle. That is, in FIG. 6, the temperature of the outside air is TA ° C., the temperature in the vicinity of the temperature sensor 30 is TB ° C., and the humidity sensor 4
If the temperature in the vicinity of 0 is TC ° C., there is no influence of body temperature when the runner's wristwatch 1 is removed from the arm, so TA, TB, and TC are all the same value. Therefore, the temperature measured by the temperature sensor 30 (TB ° C.)
Should be displayed as is.

On the other hand, the runner wristwatch 1 of this example
Then, even if it is attached to the arm, the influence of the body temperature does not affect the detection result of the temperature sensor 30, but the temperature of the outside air TA ° C. and the temperature T near the temperature sensor 30 are still.
There is a slight deviation from B ° C (the temperature measured by the temperature sensor 30). In addition, the temperature T near the temperature sensor 30
Between B ° C and the temperature TC ° C near the humidity sensor 40,
There is a slight gap. Therefore, in this example, when the runner's wristwatch 1 is worn on the wrist, the temperature sensor 30
The correction calculation M1 and the correction calculation M2 are performed on the temperature TB ° C measured by the above, and first, the outside air temperature TA ° C and the temperature TC ° C near the humidity sensor 40 are obtained. The display unit 10 displays the outside air temperature TA ° C. and the relative humidity obtained by using the temperature coefficient corresponding to the temperature TC ° C. near the humidity sensor 40.

The operation for such correction is performed by the CPU 101.
The operation is based on a program stored in advance, and the procedure of this operation is as shown in the flowchart of FIG.

In FIG. 7, the data of the detection results of the temperature sensor 30 and the humidity sensor 40 are read in step ST1, and the temperature is calculated in step ST2. This temperature is TB ° C.

Next, in step ST3, the operation state of the button 83 is determined.

Here, when it is determined by the operation on the button 83 that the wristwatch 1 is in the non-wearing state, it is assumed that the runner's wristwatch 1 is removed from the wrist, and in step ST4, the temperature (TB ° C.) itself measured by the temperature sensor 30 itself. Based on the temperature coefficient table of the ROM 107, the temperature coefficient is calculated from the temperature coefficient and the humidity sensor 40.
The humidity value displayed on the liquid crystal display panel 5 is obtained (step ST5). Then, in step ST6, the calculated temperature and relative humidity are displayed on the liquid crystal display panel 5.

On the other hand, when it is determined in step ST3 that the wristwatch 1 is worn by operating the button 83, it is determined that the wristwatch 1 for a runner is worn on the arm, and the temperature sensor 30 measures the temperature in step ST7. The calculation unit 201 performs calculation for correction on the temperature (TB ° C.), and first obtains the temperature (TA ° C.) of the outside air (correction calculation M1). In addition, the temperature measured by the temperature sensor 30 (TB
(.Degree. C.), another calculation for correction is performed by the calculation unit 201 to obtain the temperature (TC.degree. C.) near the humidity sensor 40 (correction calculation M2). Then, the temperature (TC
In step ST4, the temperature coefficient is obtained from the temperature coefficient table of the ROM 107, and based on this temperature coefficient and the measurement value of the humidity sensor 40, the liquid crystal display panel 5
Calculate the humidity to be displayed with. Then, step ST6
Then, the temperature (TA ° C.) of the outside air obtained by correcting the temperature (TB ° C.) measured by the temperature sensor 30 is displayed on the liquid crystal display panel 5. In addition, the temperature measured by the temperature sensor 30 (TB
The relative humidity obtained by using the temperature (TC ° C.) near the humidity sensor 40 obtained by correcting the temperature of the liquid crystal display panel 5
Display with.

As described above, in this example, when the runner's wristwatch 1 is removed from the wrist, it can be considered that the temperature of the outside air and the measured value of the temperature sensor 30 match each other. The temperature itself measured at 30 is displayed. On the other hand, when the wristwatch 1 for a runner is worn on the wrist, the temperature measured by the temperature sensor 30 is corrected, and the temperature and the relative humidity to be displayed are determined based on the corrected temperature. So there is no effect of body temperature.

[Running Environment Display Function] Further, in this example, the ROM 107 also stores a table for displaying whether the current environment is easy to run in A rank to E rank based on temperature and humidity. ing. ROM
The table stored in 107 is created based on the data shown in FIG.

In FIG. 8, the horizontal axis is the relative humidity, the vertical axis is the temperature, and the areas divided when connecting these points with a predetermined curve correspond to ranks A to E. Here, the ROM 107 stores a table based on a polygonal line that changes stepwise along the curve instead of the table based on the curve that divides each area.

In this example, rank A corresponds to the condition that there is almost no influence of heat and the environment is optimal for running. Under such conditions, the display area 1 shown in FIG.
“A” is displayed in the display area 142 in the upper part of the table 4. Therefore, the runner may, for example,
It will be set to 00 cc, and the guideline for the timing of water supply will be determined to be every 30 minutes.

Rank B corresponds to the condition that the influence of heat is small and the environment is suitable for running at an even pace. Under such conditions, "B" is displayed in the display area 142. . So the runner, for example,
The amount of water to be supplied at one time is 100 cc to 150 cc, and it is determined that the time for supplying water is 20 minutes.

Rank C corresponds to the condition that attention should be paid to the signs of heat injury and that the pace should be reduced. Under such a condition, “C” is displayed in the display area 142. So the runner, for example,
The amount of water to be supplied at one time is set to 150 cc to 200 cc, and the guideline for the timing of supplying water is determined to be every 15 minutes.

Rank D corresponds to the condition that one should wear a mesh garment and a hat and run at a reduced pace.
Under such a condition, “D” is displayed in the display area 142. Therefore, the runner determines, for example, that the amount of water to be supplied at one time is 150 cc to 200 cc, the guideline for the timing of water supply is every 15 minutes, and that water should be applied to the head and body.

Rank E corresponds to the condition that discomfort occurs even if the pace is reduced. Under such a condition, “E” is displayed in the display area 142. Therefore, the runner is a standard for stopping the running because it is unsuitable for running.

Here, in the runner wristwatch 1 of this example,
How the temperature, relative humidity, and running environment change over time is stored in the RAM 106 together with the split time and the lap time, so it is possible to display these information again after the competition is over. It is possible.

As described above, in the runner wristwatch 1 of this example, in addition to displaying the lap time and the split, whether or not the current environment is easy to run is displayed based on the temperature and humidity. It is convenient when doing. In addition, since whether or not the current environment is easy to run is displayed in the ranks A to E, the user can easily understand the environmental condition even while running, so that it is easy to take measures against the environment. Needless to say, the relationship between environmental conditions such as temperature and humidity and suitability for running is not limited to the above.

[Stopwatch Mode] Further, in this example, of the buttons 80 to 84 formed on the side surface and the surface of the apparatus main body 2, each time the button 80 is pressed, the stopwatch mode is set to the stopwatch mode. The read mode of the measured split time and lap time and the display mode of the lap time preset as the target time are sequentially switched.

Here, as shown in FIG. 9A,
After switching to the mode for displaying the target lap time of "15'20""in the lower display area 16, the button 83
When is pressed, as shown in FIG. 9B, the mode is switched to the target lap time setting mode. In this state, each time the button 81 is pressed, the second display portion, the minute display portion, and the time display portion are sequentially blinked in the lower display area 16, and the button 82 is pressed to switch the blinking portion numbers. It is designed to be set to a predetermined value.

Also, in any mode, the button 80
When the button is pulled out, as shown in FIG. 9 (c), the mode is switched to a mode for making corrections due to the adoption of summer time, and every time the button 81 is pressed thereafter, the second display portion, minute display portion, and time display portion are displayed. The part, the month part, the day part, and the day of the week part are sequentially flashed, and the button 82 is pressed to switch the characters of the flashing part to set a predetermined condition.

Next, the operation when the runner's wristwatch 1 is used during actual running will be described in detail below.

First, when the runner's wristwatch 1 is used with the wrist worn, the button 83 is pushed. When the button 80 is pressed in this state, the upper display area 12 and the lower display area 16 are both "0: 0'00" 0 from the display state shown in FIG. 1 as shown in FIG. 10 (a).
The display state switches to "0" and the stopwatch function switches. In this state, the stopwatch function is in the standby state.

Next, when the button 84 is pressed, the elapsed time starts to be measured. As a result, as shown in FIG. 10B, in the display unit 10, the split time “0: 52′16 ″ 27” is displayed in the upper display area 12 (first midway time display area), and the lower row is displayed. In the display area 16 (second halfway time display area) of “0: 17′52 ″ 31”, the lap time is displayed large. Note that the split time in this example is different from the meaning used in a normal marathon or the like, and refers to the time from the start to the passage of a predetermined point. The lap time in this example is different from the meaning used in a normal marathon or the like, and means the time required to pass each section.

Here, when the button 83 is pressed, the display contents are switched between the upper display area 12 and the lower display area 16, and as shown in FIG. 10C, the upper display area 1 is displayed.
2, the lap time is displayed as “0: 17′52 ″ 31”, and the split time is displayed as large in the display area 16 in the lower stage as “0: 52′16 ″ 27”. Also, button 8
When 3 is pressed again, the display contents are switched between the upper display area 12 and the lower display area 16, and as shown in FIG. 10B, a large lap time is displayed in the lower display area 12, and the upper lap time is displayed. The display returns to the state where the split time is displayed in the display area 16.

Next, when a predetermined section is passed during running, button E is pressed to determine the split time and lap time at this time. The fixed split time and lap time are updated in the RAM 10 each time.
6 is stored. Further, of the determined split time and lap time, the split time is automatically displayed in the next section after being displayed in the upper display area 12 as shown in FIG. 10B for 9 to 10 seconds. The display switches to the split time display of. On the other hand, the confirmed lap time is displayed as it is until the button 84 is pressed, and by pressing the button 84, the display is switched to the display of the lap time in the next section.

When the button 83 is pressed even while the confirmed split time and lap time are displayed,
The display contents are switched between the upper display area 12 and the lower display area 16, and the confirmed lap time is displayed in the upper display area 12 and confirmed in the lower display area 16 as shown in FIG. 10C. The split time you selected is displayed in a large size. Further, when the button 83 is pressed again, the display contents are switched between the upper display area 12 and the lower display area 16, and the lower display area 1 is displayed as shown in FIG.
The lap time is displayed large in 2 and the upper display area 1
Return to the state where the split time is displayed in 6.

In this way, the display control unit 1 shown in FIG.
00, by operating the buttons 80, 84,
Since the time circuit 104 is configured with the midway time measuring unit 400 for measuring the split time and the lap time and the display content exchange unit 300 using the button 83, the split time and the lap time can be measured, and the runner can You can freely select which of split time and lap time you want to display larger. Therefore, the runner can surely check both the split time and the lap time even if he / she does not have enough time, and can determine an appropriate pace.

Next, when the button 81 is pressed after finishing the goal, the measurement of the lap time and the split time is completed.

During this period, the lap time and the split time for each section are stored in the RAM 106. Therefore, when the button 80 is pressed after the measurement of the lap time and the split time is completed, each lap time and the split time stored in the RAM 106 are
It is displayed in the upper display area 12 and the lower display area 16 in order from the first section. To display the lap time and the split time in the next section, the button 81 may be pressed, and each time the button 81 is pressed, the lap time and the split time in the next section are displayed. In addition, in this example, not only the lap time and split time for each section but also the humidity, running environment rank, minimum temperature, or maximum temperature when running in that section are displayed.

As described above, in the runner's wristwatch 1 of this example, one of the split time and the lap time can be selected and displayed large.
After finishing running, the split time and lap time for each section can be displayed again. Moreover, after the running is completed, the environmental changes during the running can be displayed again. Therefore, even if you participate in the marathon competition alone like a citizen runner, you can certainly keep the record of this competition, which is convenient.

It should be noted that since it is only necessary that the display modes of the upper display area 12 and the lower display area 16 are significantly different, in the present example, the sizes thereof are changed. Besides, for example, in one display area,
One halfway time may be displayed by blinking, and the other halfway time may be displayed in the other display area while being lit. In this case, by operating the runner, the split time can be switched between blinking in one display area and lap time in one display area. Can easily understand the split time and lap time even if the display areas are almost the same size.
