Description

  The present invention relates to an electronic thermometer.

  The electronic thermometer is configured to measure a body temperature using a thermal sensor, detect an equilibrium temperature regarded as a body temperature, and notify / display it. Such an electronic thermometer automatically determines the end of measurement at the time of body temperature measurement. When the measurement is determined to end, the electronic thermometer notifies the end of measurement and displays the detected temperature as a body temperature. Measurements can be made.

  As a method for determining the end of measurement, a method for determining the end of measurement when it is detected that the measurement temperature is constant for a predetermined period, a method for determining the end of measurement when a predetermined time elapses by measuring with a timer, etc. have been proposed. Yes.

  There are also various methods for notifying the end of measurement. For example, in Patent Document 1, the vibration actuator 1 showing any one of vibration, buzzer operation sound, and sound by changing the input signal frequency to the coil 10 is disclosed. It is installed, and any one of the modes is selected as a notification method by operating the power switch 27, and the completion of temperature detection is notified by the selected notification method, so that it is possible to cope with a situation where no sound can be heard. .

In Patent Document 2, the vibration unit 5 and the electronic sound unit 7 are switched by the operation of the changeover switch 8, or the vibration and the electronic sound are switched by selecting them simultaneously, or the vibration and the electronic sound are generated simultaneously. The end of the temperature measurement is confirmed by informing the end of the temperature measurement without awakening the sleeping infant or the temperature-tested person with a buzzer sound. To be able to confirm.
Japanese Patent Laid-Open No. 11-304597 JP 2000-121448 A

  However, in the electronic thermometer described in Patent Document 1, it is necessary for the user to select any one of vibration, buzzer operation sound, and voice. For example, an elderly person who is difficult to hear can mistakenly select voice notification. If a patient who is bedridden or cannot sleep at his / her temperature is selected and inadvertently left unattended (not a patient), the user cannot recognize the end of the temperature measurement.

  In addition, such a problem does not occur if a notification mode in which vibration and electronic sound are generated simultaneously is selected as in the electronic thermometer of Patent Document 2, but vibration and electron are not detected as in the electronic thermometer described in Patent Document 2. If sound is generated at the same time, the battery voltage will drop and it will often fall below the BD value (Battery Detective Voltage: lower limit of usable voltage). There was a problem of lowering. Furthermore, when vibration and electronic sound occur simultaneously, there is a problem that the subject is surprised at what has happened.

FIG. 7 is a graph of changes in battery voltage when various notifications are used.
Fig. 7 shows the change in battery voltage when the buzzer notification is performed three times at intervals, and Fig. 7 (b) shows the change in the battery voltage when the vibration notification is performed three times at intervals. FIG. 7C shows a change in battery voltage when the buzzer notification and the vibration notification are performed three times at the same time.

  As shown in the upper diagram of FIG. 7A, the buzzer notification is performed by outputting a drive signal such as 4 kHz to the buzzer for one notification. On the other hand, as shown in the lower diagram of FIG. 7A, the battery voltage is instantaneously lowered when the buzzer is notified, and is restored when the buzzer is stopped. The BD indicated by a broken line in the lower diagram of FIG. 7A is the BD value described above. When the battery voltage falls below this BD value, measurement cannot be performed or measurement accuracy is reduced. However, when the battery capacity still remains, as shown in the lower diagram of FIG. 7A, the battery voltage does not fall below the BD value only with the buzzer notification.

  In general, vibration notification is performed by rotating and vibrating a vibration motor. For example, as shown in the upper diagram of FIG. 7B, a drive signal is output to the motor. (In FIG. 7B, two drive signals are output three times at intervals). Since the motor drive generally consumes more current than the buzzer, when the drive signal is output to the motor and the motor is rotated as shown in the lower diagram of FIG. 7B, the battery voltage is lower than when the buzzer is notified. However, when the battery capacity still remains, as shown in the lower diagram of FIG. 7B, the battery voltage does not fall below the BD value only by vibration notification.

  On the other hand, when the buzzer notification and the vibration notification (motor drive) are simultaneously performed as shown in FIG. 7C, the battery voltage decreases more than the case where each notification is performed independently, and the probability of being lower than the BD value. Becomes higher. As described above, if the value falls below the BD value, measurement may not be continued, or measurement accuracy may be affected.

  Therefore, the present invention solves the conventional problems, and suppresses an instantaneous drop in battery voltage by not simultaneously performing each notification in an electronic thermometer having a plurality of notification means such as buzzer notification and vibration notification. For the purpose.

  The electronic thermometer according to the present invention is an electronic thermometer comprising a measuring means for measuring a body temperature, a plurality of notification means, and a control means for controlling the operation of the plurality of notification means. The control means includes at least two notification means. Control is performed so that notifications are alternately performed.

  In particular, in the electronic thermometer comprising measuring means for measuring body temperature, buzzer notification means, vibration notification means, and control means for controlling the operation of the buzzer notification means and the vibration notification means, the control means includes the buzzer. The buzzer notifying means and the vibration notifying means are controlled so that the buzzer notifying by the notifying means and the vibration notifying by the vibration notifying means are alternately performed.

  The buzzer notification interval by the buzzer notification unit and the vibration notification interval by the vibration notification unit are the same interval.

  Further, the notification by the control means is performed when the temperature measurement value obtained by the measurement means becomes stable.

According to another aspect of the present invention, there is provided measurement means for measuring body temperature, buzzer notification means, vibration notification means, notification means selection means, control means for controlling operations of the buzzer notification means and the vibration notification means. In the equipped electronic thermometer,
A notification mode in which the control means controls so that only the buzzer notification is performed by the buzzer notification means, a notification mode in which the control means controls so that only the vibration notification by the vibration notification means is performed, and a buzzer notification by the buzzer notification means A notification mode controlled by the control unit so that vibration notification by the vibration notification unit is alternately performed, and any one of the three notification modes is based on an operation of the notification unit selection unit by a user. Selected.

  The notification means selection means also serves as a power switch of the electronic thermometer.

  In addition, the control means includes only a notification mode controlled by the control means so that only a buzzer notification is performed by the buzzer notification means and a vibration notification by the vibration notification means when the user continues to press the power switch. Control is performed so that the notification mode controlled by the control means to be performed and the notification mode controlled by the control means so that the buzzer notification by the buzzer notification means and the vibration notification by the vibration notification means are alternately performed are controlled. .

  Further, the electronic thermometer has a display unit, and the control means controls the display unit to display such that the selected notification mode is known.

  When the notification mode selected by the control unit is selected so that only the buzzer notification is performed by the buzzer notification unit when the notification mode is selected, the control unit notifies the buzzer and only the vibration notification by the vibration notification unit. When the notification mode controlled by the control means is selected to be performed, vibration notification is made, and the notification mode controlled by the control means is selected so that the buzzer notification by the buzzer notification means and the vibration notification by the vibration notification means are alternately performed. When this is done, control is performed so that buzzer notification and vibration notification are performed alternately.

  Further, when the notification mode in which the control unit controls so that only the buzzer notification is performed by the buzzer notification unit when the temperature measurement value obtained by the measurement unit is in a stable state, the control unit is selected. A buzzer is notified, and when a notification mode controlled by the control means is selected so that only vibration notification is performed by the vibration notification means, vibration is notified, and buzzer notification by the buzzer notification means and vibration notification by the vibration notification means are alternated. When the notification mode controlled by the control means is selected, the buzzer notification and the vibration notification are controlled alternately.

  Furthermore, another aspect of the present invention is an electronic thermometer comprising a measuring means for measuring body temperature, a buzzer notifying means, a vibration notifying means, and a control means for controlling operations of the buzzer notifying means and the vibration notifying means. Then, after the temperature measurement value obtained by the measurement means becomes stable and the vibration notification by the vibration notification means is performed for a predetermined time, the control means stops the vibration notification by the vibration notification means, and the buzzer Control is performed to perform buzzer notification by the notification means.

  According to another aspect of the present invention, there is provided an electronic thermometer comprising a measuring means for measuring body temperature, a buzzer notifying means, a vibration notifying means, and a control means for controlling operations of the buzzer notifying means and the vibration notifying means. In the above, after the temperature measurement value obtained by the measurement unit is in a stable state and the buzzer notification by the buzzer notification unit is performed for a predetermined time, the control unit stops the buzzer notification by the buzzer notification unit, and the vibration Control is performed to perform vibration notification by the notification means.

In the electronic thermometer according to the present invention, the control unit controls the notification by the at least two notification units alternately, thereby suppressing a decrease in the battery voltage, and further performing the buzzer notification and the vibration notification at the same time. If the electronic thermometer is designed on the assumption that the battery voltage is reduced, a backup capacitor with a large capacity must be selected. However, it is possible to suppress the battery voltage drop by alternately performing notification by at least two notification means. Therefore, a backup capacitor with a small capacity can be obtained, and generally a low-priced product can be provided.

  Hereinafter, the electronic thermometer of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a schematic block diagram for explaining a schematic configuration of an electronic thermometer of the present invention. In FIG. 1, an electronic thermometer 1 includes a measurement control circuit 2, a sensor 6 for detecting body temperature, a display device 10 for displaying measured body temperature and other information, a vibration notification device 8 for performing a notification operation, and a buzzer notification. A device 9 and a switch device 7 that is an operation switch that also serves as a power switch are provided.

  Furthermore, the measurement control circuit 2 includes a measuring device 3 that measures body temperature based on a detection signal of a sensor 6 including a thermosensitive element such as a thermistor, a timer 5 for control processing, and a switch device 7 and a measuring device. Along with input signals from the device 3 and the timer 5, a control circuit 4 is provided that outputs signals to the vibration notification device 8, the buzzer notification device 9, and the display device 10 to control these devices. As will be described later, the control circuit 4 stores a notification mode storage unit that stores a currently selected notification mode (a factory shipment value when used for the first time) and a previous measurement value (a factory shipment value when used for the first time). And a maximum temperature value storage unit for storing the maximum temperature value input by the measuring device 3.

  The control circuit 4 compares the temperature measurement value input from the measurement device 3 with the value of the maximum temperature value storage unit, and if the temperature measurement value input from the measurement device 3 is larger, the control circuit 4 stores the maximum temperature value. The temperature measurement value input from the measuring device 3 is written in the section. The maximum temperature value is updated by the processing of the control circuit 4.

  Further, the control circuit 4 outputs a drive signal for driving the vibration notification device 8 and the buzzer notification device 9, and controls the drive signal so that the notification operation of the vibration notification device 8 and the buzzer notification device 9 is not executed simultaneously. I have control.

  The vibration notification device 8 is composed of a vibration motor, and notifies the user of the end of temperature measurement by the vibration of the main body of the electronic thermometer due to the rotation of the vibration motor. The buzzer notification device 9 includes a sound generator that generates sound information such as a buzzer sound and a melody sound. The display device 10 is a display portion that displays information such as the measured body temperature.

  2A and 2B relate to the embodiment of the present invention. FIG. 2A is a plan view of electronic body temperature, and FIG. 2B is a cross-sectional view taken along line AA of FIG. 2A and 2B, reference numeral 19 denotes a resin-molded case main body, and the thermistor 6 as a temperature measuring element is provided in the sensor cap 14a in order to detect the temperature at one end side of the case main body 19. Is provided. The other end has a battery housing portion 16 for housing the battery 18, and the battery 18 is electrically connected to the circuit board. Reference numeral 17 denotes a battery lid, and the battery 18 is detachably attached to the battery housing portion 16 by opening and closing the battery lid 17. Reference numeral 12 denotes a cap that engages with the case main body 19.

A circuit board 15 on which electronic components such as a chip capacitor, a semiconductor element, and a chip resistor are mounted is disposed inside the case body 19, and the thermistor 6 is connected to the circuit board 15 with a lead wire (not shown). ing. In addition, a display device 10 including a liquid crystal display panel that displays the temperature measured by the thermistor 6 of the measurement unit 14 is disposed inside the case body 19, and is adjacent to the display device 10 and is a push button type. And a vibration notification device 8 including a vibration motor is disposed on the opposite side of the display device 10 with the switch device 7 interposed therebetween. Further, a buzzer notification device 9 is disposed between the measurement unit 14 and the display device 10. That is, the buzzer notification device 9, the display device 10, the switch device 7, and the vibration notification device 8 are arranged in this order in a direction away from the measurement unit 14 with respect to the measurement unit 14. In the thickness direction, the circuit board 15 and the vibration notification device 8 are arranged apart from each other so as not to overlap in plan view. A windshield 13 attached to the outer surface of the case body 19 with a predetermined distance from the circuit board 15 is disposed on the circuit board 15 so that the display device 10 can be visually recognized through the windshield 13. .

  Next, an operation example of the electronic thermometer of the present invention will be described using the flowchart of FIG.

  In response to the operation of the switch device 7, the electronic thermometer 1 performs vibration notification by the vibration notification device 8 and buzzer notification by the buzzer notification device 9 to notify that the switch has been turned on (start notification) ( In addition, a display operation such as displaying all the display segments of the display device 10 in a lighting state is performed (S2). The electronic thermometer according to the present invention includes a vibration notification mode in which only the vibration notification device 8 is driven to notify the vibration, a buzzer notification mode in which only the buzzer notification device 9 is driven to notify the buzzer, and a buzzer notification and vibration notification. The control circuit 4 includes a buzzer vibration notification mode that performs both, and a notification mode storage unit that stores which notification mode is currently selected from these three notification modes. Then, at the start notification, the control circuit 4 reads from the notification mode storage unit which notification mode is the currently selected notification mode, and depending on the selected notification mode, the vibration notification device 8 and / or A drive signal is output to the buzzer notification device 9 to drive the vibration notification device 8 and / or the buzzer notification device 9. Therefore, the user can experience the currently selected notification mode by the start notification, and can select an optimal notification method for the user.

  Then, the control circuit 4 outputs a signal corresponding to the notification mode selected to display the notification mode as an icon on the display device 10 so that the currently selected notification mode can be visually confirmed. (S3). FIG. 5 exemplifies the display pattern of the display device 10, FIG. 5 (a) shows the display of the display device 10 when the buzzer notification mode is selected, and FIG. 5 (b) shows the vibration notification mode. FIG. 5C shows the display of the display device 10 when the buzzer vibration notification mode is selected.

  In this way, since the selected notification mode is displayed on the display device 10, not only when the notification mode is selected, but also during the temperature measurement, it is confirmed which notification mode is selected. it can.

  Subsequently, the control circuit 4 reads and outputs the previous measurement value stored in the previous value storage unit of the control circuit 4 to the display device 10, and the display device 10 displays the previous measurement value (S4). .

  Further, the control circuit 4 confirms whether or not the switch device 7 is kept pressed by a signal input from the switch device 7 (S5), and if the switch device 7 is not pressed (when the determination of S5 is N). The temperature measurement is started (S8).

  When the temperature measurement is started, the control circuit 4 displays Low on the display device 10 (representing a state where the electronic thermometer has not yet reached 32 ° C. For example, as shown in FIG. 5D, the display of “L” is displayed. (S9), based on the detection signal of the sensor 6, it is determined whether the temperature measurement data from the measuring device 3 for measuring the body temperature is 32 ° C. or more (S10). If the temperature is less than (when the determination in S10 is N), the Low display is continued. The display device 10 displays the maximum temperature value according to the signal from the control circuit 4 (see FIG. 5E. Note that FIG. 5E is a display pattern when the buzzer vibration notification mode is selected). (S11).

  The control circuit 4 determines whether or not the measured value has reached a stable state (S12). Whether or not the measured value has reached a stable state can be determined from, for example, the rate of change of the measured value, and when the rate of change is less than a predetermined value set in advance, the measured value becomes stable. It can be determined that it has been reached. The measured value at this time represents an equilibrium temperature regarded as a body temperature. The determination of the stable state may be performed by the measuring device 3.

  If the measured value is not in a stable state (when the determination in S12 is N), the process returns to S11 and the display of the maximum temperature value is continued until it is determined that the stable state has been reached.

  When the measured value is in a stable state (when the determination in S12 is Y), the fact that the stable state has been reached is displayed on the display device 10 (S13), and the maximum temperature value is balanced assuming that the temperature measurement has been completed. The temperature is displayed on the display device 10. When the temperature measurement is completed, the control circuit 4 interrupts the measurement operation by the measurement device 3 and notifies that the stable state has been reached (S14).

  Notification that the stable state has been reached (hereinafter referred to as stability notification) is performed as follows. The control circuit 4 reads the notification mode storage unit of the control circuit 4 that stores which notification mode is currently selected among the three notification modes (vibration notification mode, buzzer notification mode, and buzzer vibration notification mode), If the selected notification mode is the buzzer notification mode, a drive signal is output so as to notify the buzzer notification only to the buzzer notification device 9, and if the selected notification mode is the vibration notification mode, the vibration notification device. When the selected notification mode is the buzzer vibration notification mode, the drive signal is output so that the buzzer notification device 9 and the vibration notification device 8 are alternately driven.

  Since the stability notification means completion of the temperature measurement, it is desirable that the notification is performed not only once but a plurality of times (for example, about three times).

  During the stability notification, when the buzzer notification mode is selected, the buzzer is notified, when the vibration notification mode is selected, the vibration is notified, and when the buzzer vibration notification mode is selected, the buzzer notification and the vibration notification are alternately performed. The end of temperature measurement can be recognized by a notification method suitable for the user.

  Further, when the buzzer vibration notification mode is selected, the buzzer notification and the vibration notification are alternately performed at the time of the stability notification, so that the voltage is not reduced. Further, even if the user cannot recognize the stable notification only by the buzzer notification, or if the vibration notification cannot recognize the stability notification as in the case where the person different from the test subject is a user. However, since the buzzer notification and the vibration notification are alternately repeated, the stable notification can be reliably transmitted to the user.

  The user usually presses the switch device 7 to save battery power after measuring the body temperature, and turns off the electronic thermometer. If the user forgets to turn off the power, after the stability notification (or drive signal for stability notification) The timer 5 may be set for a predetermined time (for example, 10 minutes) simultaneously with the output, and the power may be automatically turned off when the time is up.

In addition, considering the case where the vibration notification is erroneously selected for the temperature-inspected person who cannot measure the temperature by himself and the stability notification is not transmitted to the user (the person who is not the temperature-inspected person) even if the vibration is notified, In the case where the user does not turn off the power while performing stable notification with vibration notification, the notification method may be switched from vibration notification to buzzer notification.
For example, if the vibration notification time is 1 minute, the control circuit 4 sets the timer 5 to 1 minute at the same time that the drive signal for vibration notification is output to the vibration notification device 8, and the timer 5 times up. If the switch device 7 is not pressed by the time and, as a result, a time-up signal is output from the timer 5, the control circuit 4 stops outputting the drive signal to the vibration notification device 8 and sends the signal to the buzzer notification device 9. A drive signal may be output.

  As described above, when the vibration notification mode is selected and the user does not press the switch device 7 that also serves as the power switch while the vibration notification is performed for a predetermined time during the stability notification, the buzzer notification is issued. Since the control circuit 4 controls so as to be performed, even when the notification mode selection is mistakenly set to the vibration notification mode, the notification method is changed and the stability notification is transmitted to the user by changing the notification method to the user.

  In addition, taking into account the case where an elderly person who is hard to hear is mistakenly selected buzzer notification and the stable notification is not transmitted to the subject to be inspected even if the buzzer is notified, When the subject temperature does not turn off the power, the notification method may be switched from buzzer notification to vibration notification. For example, if the buzzer notification time is 1 minute, the control circuit 4 sets the timer 5 to 1 minute at the same time that the drive signal for buzzer notification is output to the buzzer notification device 9, and the timer 5 times up. If the switch device 7 is not pressed by the time until the timer 5 outputs a time-up signal, the control circuit 4 stops outputting the drive signal to the buzzer notification device 9 and sends the signal to the vibration notification device 8. A drive signal may be output.

  As described above, when the buzzer notification mode is selected and the user does not press the switch device 7 serving also as the power switch while the buzzer notification is performed for a predetermined time during the stability notification, the vibration notification is performed. Since the control circuit 4 controls so as to be performed, even if the notification mode selection is erroneously set to the buzzer notification mode, the notification method is changed and the stable notification is transmitted to the user by changing the notification method to the user.

  Next, the processing when the control circuit 4 determines that the switch device 7 is pressed in S5 (when the determination in S5 is Y) will be described.

  If it is determined in S5 that the switch device 7 has been pressed, the currently selected notification mode is changed (S6). That is, the control circuit 4 includes a notification mode storage unit of the control circuit 4 that stores which notification mode is currently selected among the three notification modes (vibration notification mode, buzzer notification mode, and buzzer vibration notification mode). Read and rewrite the notification mode storage unit so as to be in a different notification mode. For example, if the currently selected notification mode is the buzzer notification mode, the mode is changed to the vibration notification mode. If the currently selected notification mode is the vibration notification mode, the mode is changed to the buzzer vibration notification mode and is currently selected. If the notification mode is the buzzer vibration notification mode, the notification mode storage unit is rewritten to change to the buzzer notification mode.

  After the notification mode is changed, the control circuit 4 reads the newly selected notification mode from the notification mode storage unit, and if the selected notification mode is the buzzer notification mode, the control circuit 4 notifies the buzzer notification device 9 to notify the buzzer. If the selected notification mode is the vibration notification mode, the drive signal is output only to the vibration notification device 8 so as to notify the vibration, and the selected notification mode is buzzer vibration. In the notification mode, a drive signal is alternately output to the buzzer notification device 9 and the vibration notification device 8 so as to alternate between the buzzer notification and the vibration notification (S7). By notifying the selected notification mode in this way, the user can confirm which notification mode is the selected notification mode, and further, the degree of buzzer notification or vibration notification (buzzer sound level or vibration level). Can be confirmed.

  After notifying the selected notification mode, the control circuit 4 returns to S5 and further checks whether the switch device 7 has been pressed. If the switch device 7 continues to be pressed, the notification mode is further changed.

  As described above, when the notification mode is selected, the buzzer notification is performed when the buzzer notification mode is selected, the vibration is notified when the vibration notification mode is selected, and the buzzer notification and the vibration notification are alternately performed when the buzzer vibration notification mode is selected. Therefore, the user can grasp which notification mode is selected when the notification mode is selected, so that the notification mode is not erroneously selected.

  The notification mode changing method will be described with reference to the flowchart of FIG. 4 and the display pattern diagram of the display device 10 shown in FIG. The flowchart of FIG. 4 is for explaining the process of S6 of the flowchart of FIG. 3 in more detail.

  When the control circuit 4 determines that the switch device 7 is depressed in S5 (when the determination in S5 is Y), the process enters S6 and the notification mode is changed. First, the control circuit 4 Then, the notification mode storage unit of the control circuit 4 storing the currently selected notification mode is read, and it is determined whether it is the buzzer notification mode (S6-1).

  If it is determined in S6-1 that the value in the notification mode storage unit is the buzzer notification mode (when the determination in S6-1 is Y), the control circuit 4 changes the value in the notification mode storage unit to the vibration notification mode. (S6-5).

  If it is determined in S6-1 that the value in the notification mode storage unit is not the buzzer notification mode (when the determination in S6-1 is N), the control circuit 4 determines whether the current notification mode is the vibration notification mode. Judgment is made (S6-2).

  If it is determined in S6-2 that the value in the notification mode storage unit is the vibration notification mode (when the determination in S6-2 is Y), the control circuit 4 sets the value in the notification mode storage unit to the buzzer vibration notification mode. Change (S6-4).

  If it is determined in S6-2 that the value in the notification mode storage unit is not the vibration notification mode (when the determination in S6-2 is N), the control circuit 4 determines that the current notification mode is the buzzer vibration notification mode. Then, the control circuit 4 changes the value of the notification mode storage unit to the buzzer notification mode (S6-3).

  As described above, when the value of the notification mode storage unit is changed in the processes from S6-1 to S6-5, the control circuit 4 displays the selected notification mode on the display device 10 (S6-6). In this process, similarly to the process in S3, the control circuit 4 reads out from the notification mode storage unit which notification mode is the currently selected notification mode, and outputs a signal corresponding to the notification mode. The notification mode is displayed as an icon on the display device 10. Then, as shown in FIG. 5, when the buzzer notification mode is selected, as shown in FIG. 5 (a), when the vibration notification mode is selected, as shown in FIG. 5 (b), the buzzer vibration notification is performed. When the mode is selected, it is displayed as shown in FIG.

  As described above, the buzzer notification mode, the vibration notification mode, and the buzzer vibration notification mode can be sequentially selected, and can be selected by simply pressing and holding the switch device 7, so that the user can select the notification mode with a simple operation.

  In addition, since the user can select the notification mode by continuously pressing down the switch device 7 that is also an operation switch that also serves as a power switch, the electronic thermometer ON / OFF and the selection of the notification mode must be performed by one switch device 7. In addition, the cost can be reduced because only one switch is required.

  After the notification mode is displayed, the process proceeds to S7.

  Next, buzzer vibration notification will be described.

  FIG. 6 shows the output state of the drive signal from the control circuit 4 to the buzzer notification device 9 and the vibration notification device 8 when the buzzer vibration notification mode is selected, and the accompanying change in the battery voltage. .

  As shown in the lower part of FIG. 7 (c), if the buzzer notification and vibration notification (vibration motor drive) are performed at the same time, the battery voltage falls below the BD value, and the measurement cannot be continued or the measurement accuracy is affected. However, in the embodiment of the present invention, as shown in FIG. 6, the control circuit 4 outputs a drive signal to the buzzer notification device 9 in small increments to perform a buzzer notification for a predetermined time (in FIG. 6, a 4 kHz drive signal). After that, the output of the drive signal to the buzzer notification device 9 is stopped, the drive signal output of the drive motor of the vibration notification device 8 is performed twice, and the drive signal output of the drive motor of the vibration notification device 8 is further performed. Is stopped and the buzzer notification is performed again, so that the buzzer notification and the vibration notification are not performed simultaneously but alternately.

  In this manner, the buzzer notification and the vibration notification are not performed at the same time, but are performed alternately, thereby suppressing the decrease in the battery voltage as shown in the lower diagram of FIG. 6, so that the battery voltage does not fall below the BD value. Therefore, the measurement cannot be continued and the measurement accuracy is not affected by being below the BD value.

  In the embodiment of the present invention, the interval at which the buzzer notification is performed and the interval at which the vibration notification is performed are the same interval. This is because when the buzzer notification and the vibration notification are performed at the same interval, and the buzzer notification and the vibration notification are alternately performed, in order to comfortably and stably notify the test temperature person, the test temperature person does not feel uncomfortable. Because.

  In the embodiment of the present invention, at the start notification, the buzzer notification is performed once (8 times of 4 kHz drive signal is counted as one buzzer notification), and the vibration notification is performed once (two drive signals once). It is only counted as vibration notifications). This is because the start notification is for informing the user of the notification mode that is already selected, and therefore it is meaningless to notify the user of longer or more than necessary. This applies not only to the buzzer vibration notification mode but also to the buzzer notification mode and the vibration notification mode.

  In the embodiment of the present invention, during the stability notification, the buzzer notification is continuously performed three times in the buzzer notification mode, the vibration notification is performed three times in the vibration notification mode, and the buzzer is in the buzzer vibration notification mode. Notification and vibration notification are performed alternately three times each. Since the stability notification is a notification to notify the user that the temperature measurement is complete, it may not be confirmed once or twice, and even if it continues for longer than necessary, the battery life is shortened and only noisy. This is because about 3 times is appropriate.

  In the embodiment of the present invention, in the buzzer vibration notification mode, the buzzer notification and the vibration notification are alternately performed three times, but the buzzer notification may be performed three times and then the vibration notification may be performed three times.

In the embodiment of the present invention, since only the buzzer notification device 9 and the vibration notification device 8 are provided with the notification device, only buzzer notification, vibration notification, and buzzer vibration notification are described. The control circuit 4 performs only the buzzer notification mode in which the control circuit 4 controls to perform only the buzzer notification, the buzzer notification mode in which the control circuit 4 controls to perform only the vibration notification, and the light emission notification.
