Note that the buzzer member 304 is directly mounted on the circuit board 301. As described above, the electronic thermometer 100 according to the present embodiment is configured to be directly mounted on the circuit board 301. Similarly to other electronic components (not shown) on the circuit board 301, the buzzer member 304 is also mounted on the mounting board. It becomes possible to mount on the circuit board 301 using. In other words, compared to the case where the buzzer member is manually bonded to the inside of the housing or the holder after connecting to the circuit board via wiring as in the conventional case, the problem of variation in bonding condition is surely ensured. It can be solved. As a result, it is possible to avoid a decrease in buzzer volume due to variations in the accuracy of attaching the buzzer member.

In addition, by adopting a configuration in which the buzzer member 304 is mounted on the rear end side of the circuit board 301, it is possible to avoid a situation in which the buzzer sound is attenuated by the axilla of the subject during body temperature measurement.

Returning to the explanation of FIG. A liquid crystal display member 302 displays the calculated body temperature. A battery 303 supplies power to the circuit board 301 and the liquid crystal display member 302. The circuit board 301, the liquid crystal display member 302, and the two button batteries 303 are attached to the circuit board mounting area 201, the liquid crystal display member mounting area 202, and the battery mounting area 203, respectively.

The buzzer member is arranged on the rear end side of the circuit board.

As a result, it is possible to avoid a decrease in the buzzer volume due to variations in the mounting accuracy of the buzzer member and attenuation of the output buzzer sound, and it is possible to provide an electronic thermometer that makes it easy to hear the buzzer sound. It was.

[Second Embodiment]
In the first embodiment, the buzzer member is directly mounted on the circuit board, thereby avoiding the decrease in the buzzer volume due to the variation in the mounting accuracy of the buzzer member. However, when the buzzer member is configured to be directly mounted on the circuit board, the mounting position is limited, and therefore the buzzer volume output to the outside of the electronic thermometer 100 is appropriately set to a desired position inside the housing (for example, Compared to the case of attachment (without adhesion failure), it can be considered to decrease. Therefore, in the present embodiment, the buzzer sound output by the buzzer member is configured to propagate to the outside from a specific direction of the electronic thermometer 100 (that is, the buzzer sound output by the buzzer member can be easily heard by the user). Configured to guide in the direction).

FIG. 4 is a diagram for explaining the circuit board 401 of the electronic thermometer 100. 4 that are the same as those shown in FIG. 3 are assigned the same reference numerals, and descriptions thereof are omitted here.

3 is that a cover member 402 is provided around a position where the buzzer member 304 is directly mounted. As shown in FIG. 4, the cover member 402 has an opening 403 on the rear end side of the electronic thermometer 100, while the side and upper surfaces other than the opening 403 cover the buzzer member 304. Preferably, the upper surface of the buzzer member 304 is elastically pressed. For example, by providing a claw (projection) 402α at the tip, it can be securely fixed to the circuit board 401. Furthermore, a larger buzzer sound can be generated by the resonance of the cover member 402.

With such a configuration, the buzzer sound output from the buzzer member 304 is guided toward the rear end of the electronic thermometer 100 through the opening 403. As described above, when measuring the body temperature, the front end side of the electronic thermometer 100 is sandwiched between the subject's axilla and the rear end side protrudes into the space. Therefore, the buzzer sound output from the buzzer member 304 is transmitted to the rear end side. As a result, the buzzer sound is propagated from the rear end direction of the electronic thermometer 100 to the outside, and the buzzer sound is more audible to the user.

As is clear from the above description, in the electronic thermometer according to this embodiment,
-The buzzer member can be mounted directly on the circuit board, enabling mounting by a mounting machine, and eliminating the conventional process of bonding the buzzer member to the inside of the case or the holder manually. did.
The buzzer member is arranged on the rear end side of the circuit board.
In order to guide the buzzer sound output from the buzzer member to the rear end side of the electronic thermometer, the buzzer member is covered with a cover member having an opening only on the rear end side.

As a result, it is possible to avoid a decrease in the buzzer volume due to variations in the mounting accuracy of the buzzer member and attenuation of the output buzzer sound, and the buzzer sound propagates outward from the rear end direction of the electronic thermometer. This makes it easier to hear the buzzer sound.

In the above description, the cover member that covers all surfaces except the rear end side is used. However, the present invention is not limited to this. For example, a cover member that covers only the upper surface side and the front end side of the buzzer member is used. You may make it use.

In the above description, the cover member 402 is attached to the circuit board 401. However, the present invention is not limited to this, and may be integrally formed on the inner wall of the housing 101, for example.

[Third Embodiment]
In the second embodiment, the cover member is arranged, and the buzzer sound output from the buzzer member is guided to the rear end side of the electronic thermometer, so that the buzzer sound can be easily heard. It is not limited. For example, when inserting an electronic thermometer into the subject's axilla during body temperature measurement, the electronic thermometer 100 is typically inserted so that the front side (the side on which the liquid crystal display unit 104 is disposed) of the electronic thermometer 100 is visible to the subject. For this reason, the buzzer sound output from the buzzer member can be heard more easily by the user by guiding it to the front side of the electronic thermometer.

FIG. 5 is a diagram for explaining the circuit board 501 of the electronic thermometer 100. 5 that are the same as those shown in FIG. 3 are assigned the same reference numerals, and descriptions thereof are omitted here.

As shown in FIG. 5, the buzzer sound output from the buzzer member 304 can be guided to the front side of the electronic thermometer 100 by providing the through hole 502.

As described above, the electronic thermometer 100 is usually inserted into the subject's axilla so that the front side of the electronic thermometer 100 can be seen by the subject when measuring the body temperature, and therefore the buzzer sound output from the buzzer member 304 is displayed. However, by being led to the front side of the electronic thermometer 100, the subject can easily hear the buzzer sound.

As is clear from the above description, in the electronic thermometer according to this embodiment,
-The buzzer member can be mounted directly on the circuit board, enabling mounting by a mounting machine, and eliminating the conventional process of bonding the buzzer member to the inside of the case or the holder manually. did.
The buzzer member is arranged on the rear end side of the circuit board.
-It was set as the structure which provided a through-hole in the circuit board of the position in which the buzzer member was mounted so that the buzzer sound output from the buzzer member might be guide | induced to the front side of an electronic thermometer.

As a result, it is possible to avoid a decrease in the buzzer volume caused by variations in the accuracy of attaching the buzzer member and to attenuate the output buzzer sound, and the buzzer sound is propagated from the front side of the electronic thermometer to the outside. As a result, the buzzer sound can be heard more easily.

[Fourth Embodiment]
In the third embodiment, the electronic thermometer 100 is output from the buzzer member on the assumption that the front side of the electronic thermometer 100 is inserted into the axilla of the subject so that the subject can be seen by the subject at the time of measuring the body temperature. The buzzer sound is guided to the front side of the electronic thermometer 100, but the present invention is not limited to this.

For example, even when the front side of the electronic thermometer 100 is inserted in any direction at the time of body temperature measurement, it may be configured to make it easy to hear a buzzer sound.

FIG. 6 is a view for explaining the circuit board 601 of the electronic thermometer 100. 6 that are the same as those shown in FIG. 3 are assigned the same reference numerals, and descriptions thereof are omitted here.

3 differs from the position where the buzzer member 304 is directly mounted on the surface of the circuit board 601 (on the front side of the electronic thermometer 100 with the circuit board 301 attached to the holder 200). The buzzer member 602 is disposed on the (positioned surface). As shown in FIG. 6, the buzzer member 602 is also arranged on the front side of the circuit board 601 so that a buzzer sound having a constant volume is propagated to the outside regardless of the direction of the electronic thermometer 100 at the time of body temperature measurement. Is possible.

Further, by arranging the

same buzzer members

304 and 602 at corresponding positions on the front and back of the circuit board 601 and outputting a buzzer sound at the same time, it is possible to output a buzzer sound having a louder volume than before. .
