Description

  The present invention relates to an electronic thermometer.

  As an electronic thermometer that measures body temperature, a contact type that measures the body temperature by bringing the temperature sensor into contact with the body part to be measured (such as the armpit, sublingual, etc.), or non-contact that measures heat radiation from the eardrum, etc. Something of the formula has been proposed. A general contact-type electronic thermometer is provided in a substantially pen-shaped elongated main body, a temperature sensing part provided at the front end of the main body, a display part such as a measurement result provided on the side surface of the main body, and a rear part or side surface of the main body. The power switch and a control unit that executes temperature measurement, calculation, and the like built in the main body.

  The most common part to be measured in such an electronic thermometer is the armpit, and the user measures the electronic thermometer inside the clothes under the armpit for several tens of seconds to several minutes. The user needs to keep the electronic thermometer in contact with his armpit in an invisible position on the inside of the clothes. Especially when taking out a child during measurement or after measurement, accidentally press the power switch to turn off the power. There is a possibility.

  Although there is a structure that is not the same as the surface on which the measurement result etc. is displayed and is embedded in the end opposite to the temperature sensing part so that it can not be pressed easily, There are disadvantages such as an increase in cost due to an increase in the number of parts and difficulty in operation for a person with a large fingertip. Considering these, it is desirable to install the operation switch on the same surface as the display surface, but on the other hand, erroneous operations such as pressing the switch during measurement are likely to occur. In order to prevent such an erroneous operation, a method (so-called “long press”) is proposed in which the power is not cut off unless the power switch is kept pressed for a predetermined time (see Patent Documents 1 and 2). The time until the power is turned off (long pressing time) is generally set to about 1.5 seconds to 2 seconds so that it can be clearly distinguished from pressing due to an erroneous operation.

  However, according to the investigations of the present inventors, it is found that there is a difference in the preferred long press time depending on the age of the user (child, adult, elderly person, etc.) and the environment (home, medical institution, etc.) where the thermometer is used I came. For example, in the case of an infant or a child, it is better to set a long press time from the viewpoint of preventing power-off due to an erroneous operation. However, in the case of an adult, if the long press time is too long, it may be annoying. Some elderly and disabled persons have difficulty in long-pressing the power switch. As described above, a method that is advantageous for a specific user may be disadvantageous for another user. Therefore, an appropriate operation prevention measure according to the user and the use environment is desired.

  In addition, in the conventional method, since the user cannot recognize the preset switch pressing time until the power is turned off, it is difficult to grasp how long the power is turned off and the usability problem Was also pointed out.

  Although it is not a thermometer, as a more complicated method, a method is proposed in which the combination of the type of switch and the length of the pressing time is stored as a pattern, and security cannot be released unless the switch is pressed according to the pattern. (See Patent Document 3).

However, such complicated functions are excessive for thermometers, and are difficult to apply to simple devices with few switches such as thermometers. Moreover, since the length of the pressing time is sensuous, another user cannot reproduce the combination of the length of the pressing time according to the pattern set by one user, and the power cannot be turned off. there is a possibility. Therefore, such a function is not appropriate for a thermometer that may be used by a plurality of persons, and a simpler and more reliable erroneous operation prevention measure is desired.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an electronic thermometer with excellent usability having an erroneous operation preventing function that can flexibly respond to a request of a user or a use environment. There is.

  In order to achieve the above object, the present invention adopts the following configuration.

  The electronic thermometer according to the first aspect of the present invention includes a temperature sensor that measures body temperature, a power switch, a display unit, a storage unit that stores a set value, and a time corresponding to the set value stored in the storage unit. A power control unit that turns off the electronic thermometer when the power switch is continuously pressed, and a setting change unit that changes a setting value stored in the storage unit based on a user operation; .

  The expression “time corresponding to the set value” is a table or conversion if there is a configuration in which the set value directly represents the length of time (for example, the set value is “2” and the time is “2 seconds”). It means that the structure which calculates | requires time from a setting value using a formula can also be taken.

  According to the above configuration, since the power is not turned off unless the power switch is continuously pressed for a set time or longer, it is possible to prevent the power from being cut off due to unintentional contact with the power switch or the like. In addition, since the user can arbitrarily set the pressing time until the power is turned off, the user can flexibly respond to the user's preference and usage environment requirement, and can realize an electronic thermometer with excellent usability. .

  By the way, it is advantageous for the user to arbitrarily set the pressing time until the power is turned off.On the other hand, when the user forgets the set value or when a person other than the user uses the thermometer, There is a demerit that the specific operation of turning off the power becomes unknown. For example, when the pressing time is set to a very long value (10 seconds), a person who does not know the setting does not turn off the power by pressing the power switch normally for a long time or pressing it several times. If you do not know how to turn off the power, you may be confused or you may suspect a thermometer malfunction. Since the thermometer is often shared by a plurality of persons at home, workplace, medical institution, etc., the above-mentioned problems are particularly likely to occur.

  Therefore, it is preferable that the power control unit outputs a screen representing the remaining time until the power is turned off to the display unit while the power switch is pressed.

  According to this configuration, when the pressing of the power switch is started to turn off the power, the set value of the pressing time can be grasped. Furthermore, if the power switch is continuously pressed, the remaining time is counted down, so that it is easy to visually understand how long the power switch is pressed to turn off the power. The remaining time may be expressed in any form such as numbers, characters, figures, images, and the like.

  Further, it is preferable that the power supply control unit turns off the electronic thermometer even when the power switch is continuously pressed a number of times corresponding to the set value.

  A person who does not know the specific operation of turning off the power or a person who does not know the set value of the pressing time has a high probability of attempting an operation of long-pressing or repeatedly pressing the power switch. Therefore, the usability of the electronic thermometer is improved by configuring the power supply to be turned off in both cases of long press and continuous press. Further, continuous pressing of the power switch can turn off the power in a shorter time than pressing the power switch for a long time, and is effective when the long pressing is troublesome or when it is desired to save time.

  Note that “continuously pressed” means that the button is pressed a plurality of times so as to satisfy a predetermined time condition. For example, when the second press is performed within a predetermined specified time from the start or end of the first press, the first and second presses may be regarded as “continuous”. Alternatively, when the total time required for n times of pressing is equal to or less than a predetermined time, the n times of pressing may be regarded as “continuous”. In addition, the expression “number of times corresponding to the set value” may be a table or conversion formula if there is a configuration in which the set value directly represents the number of times (for example, the set value is “2” and the number of times is “2 times”). This means that a configuration in which the number of times is obtained from the set value using can be taken.

  The electronic thermometer according to the second aspect of the present invention includes a temperature sensor that measures body temperature, a power switch, a display unit, a storage unit that stores setting values, and the number of times corresponding to the setting values stored in the storage unit. Only when the power switch is continuously pressed, a power control unit that turns off the power of the electronic thermometer, a setting change unit that changes a setting value stored in the storage unit based on a user operation, Is provided.

  According to this configuration, since the power is not turned off unless the power switch is continuously pressed more than the set number of times, it is possible to prevent the power from being cut off due to unintentional contact with the power switch or the like. In addition, since the user can arbitrarily set the number of times the power is pressed until the power is turned off, the user can flexibly respond to the user's preference and usage environment requirement, and can realize an electronic thermometer with excellent usability. .

  By the way, while it is beneficial for the user to arbitrarily set the number of presses until the power is turned off, when the user himself forgets the set value or when a person other than the user uses the thermometer, There is a demerit that the specific operation of turning off the power becomes unknown. For example, when the number of times of pressing is set to a very large value (10 times), a person who does not know the setting does not turn off the power by pressing the power switch normally for a long time or pressing it several times. If you do not know how to turn off the power, you may be confused or you may suspect a thermometer malfunction. Since the thermometer is often shared by a plurality of persons at home, workplace, medical institution, etc., the above-mentioned problems are particularly likely to occur.

  Therefore, it is preferable that the power control unit outputs a screen representing the remaining number of times until the power is turned off to the display unit every time the power switch is pressed.

  According to this configuration, when the pressing of the power switch is started to turn off the power, the set value of the number of pressings can be grasped. Further, if the power switch is repeatedly pressed, the remaining number of times is counted down, so that it is easy to visually understand how many times the power switch is pressed again to turn off the power. Note that the remaining number of times may be expressed in any form such as numbers, characters, figures, images, and the like.

In addition, it is preferable that the power supply controller turns off the electronic thermometer even when the power switch is continuously pressed for a time corresponding to the set value.

  A person who does not know the specific operation of turning off the power or a person who does not know the set value of the pressing time has a high probability of attempting an operation of long-pressing or repeatedly pressing the power switch. Therefore, the usability of the electronic thermometer is improved by configuring the power supply to be turned off in both cases of long press and continuous press.

  The setting change unit preferably determines a setting value (pressing time or number of pressings) to be set in the storage unit according to a length of time that a predetermined switch is continuously pressed.

  According to this configuration, the user can set the setting value with a simple and intuitive operation. This setting method is particularly suitable for setting the pressing time. This is because the operation at the time of setting is the same as that at the time of turning off the power, and there is an advantage that the setting can be performed while experiencing (confirming) the length of the pressing time when the power is turned off.

  It is preferable that the setting change unit outputs a screen representing a time during which the predetermined switch is continuously pressed to the display unit while the predetermined switch is pressed.

  According to this configuration, since the setting content can be visually confirmed, the operability at the time of setting can be improved and a setting error can be prevented.

  The setting change unit may determine a setting value (pressing time or number of pressings) to be set in the storage unit according to the number of times a predetermined switch is pressed.

  According to this configuration, the user can set the setting value with a simple and intuitive operation. When using this method for setting the pressing time (for example, setting 1 second when pressed once, 2 seconds when pressing twice), the advantage of being able to clearly specify the length of the pressing time to be set There is. In addition, when this method is used for setting the number of times of pressing, the operation at the time of setting is the same as that at the time of turning off the power.

  It is preferable that the setting change unit outputs a screen indicating the number of times the predetermined switch is pressed to the display unit each time the predetermined switch is pressed.

  According to this configuration, since the setting content can be visually confirmed, the operability at the time of setting can be improved and a setting error can be prevented.

  It is preferable that the setting changing unit starts a process of changing the setting value when the predetermined switch is continuously pressed for a predetermined time in a state where the electronic thermometer is turned off. Alternatively, it is also preferable that the setting changing unit starts the process of changing the setting value when the predetermined switch is continuously pressed a predetermined number of times in a state where the electronic thermometer is turned off.

  According to this configuration, the setting value change mode is not entered unless a predetermined switch operation such as a long press or a predetermined number of continuous presses is performed, so that a situation in which the set value changes due to an erroneous operation or a mischief of a child can be prevented. Moreover, since the set value change mode can be entered only from the power-off state, it is possible to prevent a situation where the set value change mode is unintentionally entered during body temperature measurement, which is preferable from the viewpoint of usability.

  It is preferable that the power switch also serves as the predetermined switch.

  Thereby, since it is not necessary to increase the number of switches of a thermometer, the complexity of a structure and the increase in cost can be suppressed.

  The present invention may be understood as an electronic thermometer having at least a part of the above means, or as a control method of an electronic thermometer including at least a part of the above processing. Each of the above means and processes can be combined with each other as much as possible to constitute the present invention.

  ADVANTAGE OF THE INVENTION According to this invention, it is possible to provide the electronic thermometer excellent in usability which has the misoperation prevention function which can respond flexibly to the request | requirement of a user or a use environment.

  Exemplary embodiments of the present invention will be described in detail below with reference to the drawings. However, the dimensions, materials, shapes, relative arrangements, and the like of the component parts described in this embodiment are not intended to limit the scope of the present invention only to those unless otherwise specified. .

<First Embodiment>
(Appearance of electronic thermometer)
FIG. 1 is a view showing the appearance of an electronic thermometer according to the first embodiment of the present invention.

  The electronic thermometer 1 generally includes a wide thermometer body on which the display unit 3 is provided, and a rod-like probe that extends from the thermometer body. The thermometer main body has a housing made of a resin material, and an electronic component (described later) is built in the housing. A display unit 3 and a power switch 2 are provided on the front surface of the thermometer main body. The probe is a portion that is sandwiched between measured portions such as the armpit and the tongue during temperature measurement, and is made of a resin material or an elastomer. A temperature sensor 4 made of stainless steel is provided at the tip of the probe, and a temperature sensor (described later) is built in the temperature sensor 4.

(Configuration of electronic thermometer)
FIG. 2 is a block diagram of an electronic thermometer. As shown in FIG. 2, the electronic thermometer 1 includes a CPU (central processing unit) 11, a temperature sensor 9, an A / D converter 10, a power switch 2, a battery 8, a display unit 3, a buzzer 13, and a storage unit 14.

  The temperature sensor 9 is an element that converts the heat conducted from the temperature sensing unit 4 into an electrical signal, and is composed of, for example, a thermistor. The A / D converter 10 is a circuit that converts an analog electric signal output from the temperature sensor 9 into a digital signal, and includes, for example, a CR oscillation circuit. A digital signal output from the A / D converter 10 is captured by the CPU 11.

  The power switch 2 is a switch used for switching on / off the power source of the electronic thermometer. As will be described later, in the present embodiment, the power switch 2 also serves as a switch for changing a set value used for power-off control. In the present embodiment, the power switch 2 is arranged on the same surface as the display unit 3 by using a sheet switch (membrane switch), thereby reducing the number of parts and the cost by simplifying the structure. The design is improved. Note that if the switch is arranged on the same surface as the display unit 3, an erroneous operation such as pressing the switch during measurement is likely to occur. Therefore, it is necessary to take measures to prevent power off due to an erroneous operation. In the present embodiment, as described later, a long press of the power switch 2 is requested to turn off the power.

  The display unit 3 is a display device for displaying information such as a measurement result of the body temperature and an operation state, and is configured by, for example, an LCD. In addition, you may utilize other display devices, such as LED and an organic EL display, instead of LCD as a display part. The buzzer 13 is a notification unit that generates a notification sound. The battery 8 is a power source that supplies power to the CPU 11.

  The CPU 11 measures (calculates) the body temperature based on the digital signal input from the A / D converter 10, controls the display unit 3, the buzzer 13, etc., power on / off control of the electronic thermometer, and stores in the storage unit 14. This is a circuit for executing a process for changing the set value. That is, in the present embodiment, the CPU 11 functions as a power control unit and a setting change unit according to the present invention. The storage unit 14 is a rewritable nonvolatile memory, and stores various data including setting values used for power-off control, programs executed by the CPU 11, and the like.

(Start process)
FIG. 3 is a flowchart showing an activation process of the electronic thermometer.

  When the power switch 2 is pressed while the electronic thermometer is off (S10), the CPU 11 measures the pressing time. When the power switch 2 is continuously pressed for a predetermined time (S11; Yes), the CPU 11 starts changing the setting value used for power-off control (S12). On the other hand, when the pressing time of the power switch 2 is shorter than the predetermined time (S11; No), the CPU 11 executes a normal body temperature measurement process (S13).

  Here, the “predetermined time” is a condition of a long press time for shifting to the set value change mode. The value is set in the storage unit 14 at the time of manufacture, and is set to about 2 seconds, for example. Note that as a condition for shifting to the setting value change mode, continuous pressing may be requested instead of long pressing. Specifically, when the power switch 2 is continuously pressed for a predetermined number of times (for example, three times) in the power-off state, the mode shifts to the setting value change mode. “Continuously pressed” means that a plurality of times of pressing are performed so as to satisfy a predetermined time condition. In this embodiment, when the second press is performed within 0.5 seconds from the end of the first press, the first and second presses are regarded as “continuous”.

  According to this configuration, the setting value change mode is not entered unless a predetermined switch operation such as a long press or a continuous press is performed, so that it is possible to prevent a situation in which the set value changes due to an erroneous operation or a child's mischief. Moreover, since the set value change mode can be entered only from the power-off state, it is possible to prevent a situation where the set value change mode is unintentionally entered during body temperature measurement, which is preferable from the viewpoint of usability.

(Setting value change processing)
FIG. 4 is a flowchart showing the setting value changing process in the first embodiment. 5A to 5F are diagrams showing examples of screen display of setting value change processing.

  When the electronic thermometer is turned on, the display unit 3 is fully lit. Then, when the set value changing process is started (S12 in FIG. 3), the CPU 11 blinks the numeric part of the display unit 3 (FIG. 5A) and notifies the user that the mode has changed to the set value changing mode (S20). When the power switch 2 is once stopped and then pressed again, measurement of the pressing time is started (S21). At this time, the memory mark “m” blinks on the display unit 3 to notify the user that the pressing time is being measured (FIG. 5B).

The CPU 11 monitors whether the power switch 2 is continuously pressed (S22).
Every time 1 second elapses, the pictogram display on the display unit 3 is updated (S23). In the example of FIG. 5B to FIG. 5D, a screen representing the continuous pressing time of the power switch 2 with a number (seconds) is displayed as a pictographic display.

  When the user stops pressing the power switch 2 (S22; No), the CPU 11 determines a setting value according to the length of the continuous pressing time up to that point, and saves the value in the storage unit 14 (S24). . At this time, on the display unit 3, the flashing of the memory mark stops and the number indicating the continuous pressing time (setting value) flashes three times to notify the user that the change of the setting value is completed (FIG. 5E). When the change of the set value is completed, the thermometer is automatically turned off after 3 seconds (FIG. 5F).

  According to this configuration, the user can set the setting value by a simple and intuitive operation of pressing and holding the power switch 2 for a long time. Further, since the setting contents can be visually confirmed by pictographic display, the operability at the time of setting can be improved and setting errors can be prevented. As will be described later, the electronic thermometer of the present embodiment can be set while actually feeling (confirming) the length of the pressing time when the power is turned off because the operation when the power is turned off is also a long press of the power switch 2. There is also an advantage.

  5A to 5F, the pressing time is measured in units of 1 second, and the number of seconds is pictically displayed. However, the configuration of the present invention is not limited to this. For example, the pressing time may be measured in units smaller than 1 second. If the length of the pressing time can be expressed, characters, figures, images, etc. may be displayed instead of numbers. 6A to 6F show other screen display examples of the setting value changing process. In this example, each time the power switch 2 is pressed for 0.5 seconds, the square mark (□) increases by one. Thereby, the set value from 0 second to 3 seconds can be set in increments of 0.5 seconds. In the example of FIG. 6E, the set value is 2 seconds because there are four square marks.

  Although the data format of the set value is arbitrary, it is preferable to use integer type data representing the number of seconds of pressing time or the number of square marks.

(Body temperature measurement process)
When the body temperature measurement process is started, the CPU 11 executes an initialization process and then displays on the display unit 3 that the preparation for body temperature measurement is completed. When the user starts the measurement of the body temperature by bringing the temperature sensing unit 4 into contact with the measurement target part such as the armpit, temperature signals are sequentially taken into the CPU 11 from the temperature sensor 9 via the A / D converter 10. CPU11 calculates the predicted value of body temperature from the temperature taken in sequentially, its increase rate, etc., or calculates the actual value of body temperature. Those measurement results are displayed on the display unit 3. Further, a notification sound is output from the buzzer 13 at the timing when the predicted value is displayed and when the actual measurement is completed. The measurement result is continuously displayed on the display unit 3 until the electronic thermometer is turned off.

(Power off processing)
FIG. 7 is a flowchart showing the power-off process in the first embodiment. 8A to 8D are diagrams showing examples of screen display of power-off processing. In the present embodiment, the electronic thermometer can be turned off by pressing and holding the power switch 2.

As shown in FIG. 8A, the CPU 11 monitors the pressing of the power switch 2 with the measurement result displayed on the display unit 3 (S40) (S41). When it is detected that the power switch 2 is pressed (S41; Yes), the CPU 11 reads the setting value from the storage unit 14 and displays the time (a number representing the setting value) on the display unit 3 (FIG. 8B). While the power switch 2 is continuously pressed, the CPU 11 updates the screen with the passage of time and subtracts the displayed number (S42) (FIG. 8C). That is, a screen representing the remaining time until the power is turned off is output on the display unit 3.

  When the power switch 2 continues to be pressed for the set time (here, 2 seconds) (S43; Yes), the CPU 11 turns off the electronic thermometer (S44) (FIG. 8D). When the pressing is stopped before the set time (S43; No → S41; No), the display returns to the measurement result display (S40).

  If the power is unexpectedly turned off due to an erroneous operation during the measurement, the power is turned on again and the body temperature is measured again, which is not preferable from the viewpoint of usability and battery life. In that respect, according to the configuration of the present embodiment, since the power supply is not turned off unless the power switch 2 is continuously pressed for a set time or longer, the power supply is cut off by unintentional contact with the power switch 2 or the like. The situation can be prevented.

  In addition, since the user can arbitrarily set the pressing time until the power is turned off, the user can flexibly respond to the user's preference and usage environment requirement, and can realize an electronic thermometer with excellent usability. . For example, in a hospital outpatient, etc., it is necessary to make the patient measure the body temperature and record the measurement result in a record. If the patient himself can easily turn off the thermometer, the nurse will not be able to confirm the measurement result directly, which is not preferable. In such a situation, setting the pressing time to a large value is effective as a measure for reducing the power-off by the patient.

  By the way, it is advantageous for the user to arbitrarily set the pressing time until the power is turned off.On the other hand, when the user forgets the set value or when a person other than the user uses the thermometer, There is a demerit that the specific operation of turning off the power becomes unknown. For example, when the pressing time is set to a very long value (10 seconds), a person who does not know the setting does not turn off the power by pressing the power switch normally for a long time or pressing it several times. If you do not know how to turn off the power, you may be confused or you may suspect a thermometer malfunction. Since the thermometer is often shared by a plurality of persons at home, workplace, medical institution, etc., the above-mentioned problems are particularly likely to occur.

  However, according to the configuration of the present embodiment, when pressing of the power switch 2 is started to turn off the power, the screen display as shown in FIG. 8B is made, so that the set value of the pressing time can be grasped. Further, if the power switch 2 is continuously pressed, the remaining time is counted down as shown in FIG. 8C, so that it is easy to visually understand how much further the power is pressed to turn off the power.

  The remaining time may be expressed in any form such as numbers, characters, figures, images, and the like. However, the thermometer has a restriction that the display area is small and the display content is limited, unlike a highly functional device such as a mobile phone or an information terminal. Therefore, it is important to devise a visually easy-to-understand display using 7-segment display. 9A to 9F are diagrams showing other screen display examples of the power-off process. Each time the power switch 2 is pressed for 0.5 seconds, the square mark (□) decreases by one to indicate the remaining time until the power is turned off.

Second Embodiment
FIG. 10 is a view showing the appearance of an electronic thermometer according to the second embodiment of the present invention. FIG. 11 is a block diagram of an electronic thermometer according to the second embodiment.

  In the above embodiment, the power switch 2 also serves as a setting change switch. However, in the second embodiment, a setting change setting switch 5 is provided separately from the power switch 2. Also with this configuration, the same effects as those of the first embodiment can be achieved.

<Third Embodiment>
In the setting value changing process of the above embodiment, the setting value is determined according to the length of time that the switch is continuously pressed. In the setting value changing process of the third embodiment, the switch is pressed. The set value is determined according to the number of times.

(Setting value change processing)
FIG. 12 is a flowchart showing a setting value change process in the third embodiment. The screen display of the setting change process is the same as that of the above embodiment, and will be described with reference to the display examples of FIGS. 5A to 5F.

  When the electronic thermometer is turned on, the display unit 3 is fully lit. Then, when the set value changing process is started (S12 in FIG. 3), the CPU 11 blinks the numerical portion of the display unit 3 (FIG. 5A) and notifies the user that the mode has changed to the set value changing mode (S30). If the power switch 2 is once stopped and then pressed again, measurement of the number of times of pressing is started (S31). At this time, the memory mark “m” blinks on the display unit 3 to notify the user that the number of times of pressing is being measured (FIG. 5B).

  The CPU 11 monitors whether or not the power switch 2 is continuously pressed (S32), and updates the pictogram display on the display unit 3 every time it is pressed (S33). In the example of FIG. 5B to FIG. 5D, as a pictographic display, a screen that displays the number of times the power switch 2 is continuously pressed is displayed.

  When pressing of the power switch 2 is not detected for a predetermined time (for example, 1 second) or longer (S32; No), the CPU 11 determines a setting value according to the number of pressings up to that point, and stores the value in the storage unit 14. (S34). At this time, on the display unit 3, the flashing of the memory mark stops, the number indicating the number of times of pressing (setting value) flashes three times, and informs the user that the setting value has been changed (FIG. 5E). When the change of the set value is completed, the thermometer is automatically turned off after 3 seconds (FIG. 5F).

  According to this configuration, the user can set the set value by a simple and intuitive operation of repeatedly pressing the power switch 2 (or the setting switch 5). Further, since the setting contents can be visually confirmed by pictographic display, the operability at the time of setting can be improved and setting errors can be prevented. When using this method for setting the pressing time (for example, setting 1 second when pressed once, 2 seconds when pressing twice), the advantage of being able to clearly specify the length of the pressing time to be set There is. Further, when this method is used for setting the number of times of pressing as in the fourth embodiment to be described later, since the operation at the time of setting is the same as the operation at the time of power off, the operation at the time of power off is experienced (confirmed). There is an advantage that it can be set.

<Fourth embodiment>
In the above embodiment, the power is turned off when the switch is pressed for a set time, but in the fourth embodiment, the power is turned off when the switch is continuously pressed for the set number of times. To.

  The set value of the number of times of pressing can be set by the same method as described in the first embodiment or the third embodiment. That is, a numerical value “n” can be set by long-pressing the switch for n seconds or pressing it n times. However, in the above embodiment, the numerical value “n” is used as a value representing time (seconds). On the other hand, this embodiment is different only in that the numerical value “n” is used as a value representing the number of times of pressing.

(Power off processing)
FIG. 13 is a flowchart showing power-off processing in the fourth embodiment. The screen display when the power is turned off is the same as that of the above embodiment, and will be described with reference to the display examples of FIGS. 8A to 8D.

  As shown in FIG. 8A, the CPU 11 monitors the pressing of the power switch 2 (S51) while displaying the measurement result on the display unit 3 (S50). When the pressing of the power switch 2 is detected (S51; Yes), the CPU 11 reads the setting value from the storage unit 14 and displays the number of times of pressing (a number representing the setting value) on the display unit 3 (FIG. 8B). . Each time the power switch 2 is repeatedly pressed within a specified time (for example, 0.5 seconds) (S54), the CPU 11 updates the screen and subtracts the displayed number (S52) (FIG. 8C). . That is, a screen indicating the remaining number of times until the power is turned off is output on the display unit 3.

  When the power switch 2 is continuously pressed for the set number of times (here, twice) (S53; Yes), the CPU 11 turns off the electronic thermometer (S55) (FIG. 8D). If the interval at which the power switch 2 is pressed exceeds the specified time (S54; No), the display returns to the measurement result display (S50).

  Even in the configuration of the present embodiment, the same effects as those of the above-described embodiment can be achieved. That is, according to the configuration of the present embodiment, the power supply is not turned off unless the power switch 2 is repeatedly pressed more than the set number of times, so that the power supply is cut off due to unintentional contact with the power switch 2 or the like. Can be prevented.

  In addition, since the user can arbitrarily set the number of times the power is pressed until the power is turned off, the user can flexibly respond to the user's preference and usage environment requirement, and can realize an electronic thermometer with excellent usability. . For example, in a hospital outpatient, etc., it is necessary to make the patient measure the body temperature and record the measurement result in a record. If the patient himself can easily turn off the thermometer, the nurse will not be able to confirm the measurement result directly, which is not preferable. In such a situation, setting the number of pressings to a large value is effective as a measure for reducing power-off by the patient.

  By the way, while it is beneficial for the user to arbitrarily set the number of presses until the power is turned off, when the user himself forgets the set value or when a person other than the user uses the thermometer, There is a demerit that the specific operation of turning off the power becomes unknown. For example, when the number of times of pressing is set to a very long value (10 seconds), a person who does not know the setting does not turn off the power by normally pressing the power switch for a long time or pressing it several times. If you do not know how to turn off the power, you may be confused or you may suspect a thermometer malfunction. Since the thermometer is often shared by a plurality of persons at home, workplace, medical institution, etc., the above-mentioned problems are particularly likely to occur.

  However, according to the configuration of this embodiment, when pressing of the power switch 2 is started to turn off the power, a screen display as shown in FIG. 8B is made, so that the set value of the number of pressings can be grasped. Furthermore, if the power switch 2 is repeatedly pressed, the remaining number of times is counted down as shown in FIG. 8C, so that it is easy to visually understand how many times the power switch 2 is pressed to turn off the power.

  This display is very effective as an operation guide for those who do not know the operation at all. This is because, when a person who does not know the operation at all turns off the power, he / she presses the power switch once, and if it does not turn off, the user is likely to press the power switch once again. At that time, if the numbers and figures displayed on the screen decrease, the person can intuitively recognize the power-off operation method.

<Fifth Embodiment>
In the fifth embodiment, the power can be turned off by either the long press or the continuous press. Since other configurations are the same as those of the above-described embodiment, description thereof is omitted.

  For example, when a numerical value “3” is set as the setting value in the storage unit 14, the CPU 11 determines whether the power switch 2 is continuously pressed for 3 seconds or continuously pressed 3 times. When such an operation is performed, the thermometer is turned off.

  A person who does not know the specific operation of turning off the power or a person who does not know the set value of the pressing time and the number of pressings is highly likely to try an operation of long-pressing or repeatedly pressing the power switch. Therefore, the usability of the electronic thermometer is improved by configuring the power supply to be turned off in both cases of long press and continuous press. Further, continuous pressing of the power switch can turn off the power in a shorter time than pressing the power switch for a long time, and is effective when the long pressing is troublesome or when it is desired to save time.

  Although the first to fifth embodiments have been described above, the configuration of the present invention is not limited to these embodiments, and can be appropriately modified within the scope of the technical idea. For example, it is also preferable to appropriately combine the configurations described in the above embodiments.

  In the above embodiment, the remaining time (or remaining number of times) is displayed by reducing the number or the number of marks, but the display mode of the remaining time and the remaining number of times is not limited to this. For example, the number or the number of marks may be increased according to the pressing time or the number of pressing times. If it is known that the power is turned off when the number or the number of marks reaches a predetermined number, the remaining time and the remaining number of times can be expressed even in such a display mode. Alternatively, the remaining time and the remaining number of times may be expressed by changing the shape and position of the mark according to the pressing time or the number of times of pressing.

  Further, the configuration, shape, arrangement, and the like of the power switch and the setting switch are not limited to those of the above embodiment. For example, it is also preferable to use a touch sensor type switch as a power switch or a setting switch. In the case of a touch sensor, an operation of touching a switch with a fingertip (an operation of lightly pressing) corresponds to “pressing a switch”. Further, the power switch and the setting switch may be arranged on the end of the thermometer main body (end opposite to the temperature sensing unit) or on a surface (side surface or back surface) different from the display unit.
