The bottom surface portion 52R is continuous with the bottom surface portion 52S and is located on the other end side (rear end side) of the electronic thermometer 100. The bottom surface portion 52S is formed shallower than the bottom surface portion 52R so that the electronic thermometer 100 can be easily inserted toward the measurement subject's armpit or tongue.

  A concave portion 52T is provided in a groove shape along the longitudinal direction of the electronic thermometer 100 at the approximate center of the bottom surface portion 52S. When the electronic thermometer 100 is assembled, the thermistor 10 (lead wire 12) is accommodated in the recess 52T.

  The annular wall 52U and the upper end 52K of the case body 52 form an opening toward the side where the internal device 18 is accommodated so that the internal device 18 can be accommodated in one direction with respect to the case body 52. .

  With reference to FIG. 1 and FIG. 2, the dish-shaped storage area 60 is provided on the distal end side in the longitudinal direction of the case body 52. An opening 52H (see FIG. 2) is provided near the tip of the bottom surface 52S of the case body 52. The dish-shaped storage area 60 is fitted into the opening 52H. The dish-shaped storage area 60 may be bonded to the bottom surface portion 52S of the case body 52 by an adhesive, heat welding, ultrasonic welding, or the like. The dish-shaped storage area 60 may be joined to the case body 52 by insert molding or the like.

  The dish-shaped storage area 60 is made of a metallic member having high thermal conductivity such as stainless steel or aluminum. The dish-like storage area 60 is formed so as to bulge away from the sheet-like member 51. The dish-shaped storage area 60 is formed with an opening toward the side where the temperature-sensitive part 11 is stored so that the temperature-sensitive part 11 can be stored in one direction with respect to the dish-shaped storage area 60. The bottom portion 60T of the dish-shaped storage area 60 may be formed flat (a mode shown in FIG. 2), may be formed in a spherical shape (not shown), and becomes thinner toward the tip. It may be formed in a conical shape (such as a conical shape or a triangular pyramid shape) or a frustum shape.

  In the state in which the electronic thermometer 100 is assembled (see FIG. 2), the dish-shaped storage area 60 and the sheet-shaped member 51 are disposed to face each other with a space therebetween. The temperature sensing unit 11 is accommodated inside the dish-shaped accommodation area 60. A part of the outer peripheral surface of the temperature sensing unit 11 is in contact with the inner peripheral surface 60S of the dish-shaped storage region 60 at the contact portion P1. The remainder of the outer peripheral surface of the temperature sensing unit 11 is separated from the inner peripheral surface 60S of the dish-shaped storage area 60 with an interval S1.

Moreover, the temperature sensing part 11 may be joined to the inner peripheral surface 60S by soldering or the like.

  Referring again to FIG. 1, when the electronic thermometer 100 is assembled, the built-in device 18 (the thermistor 10, the control board 20, the display unit 30, the power supply unit 40, and the board 29) includes the sheet-like member 51 and the case body. 52.

  The built-in device 18 is accommodated in the case body 52. The built-in device 18 may be accommodated in the case body 52 in a state where the built-in device 18 is fixed to the sheet-like member 51 by means such as adhesion. In this case, the built-in device 18 is attached to the sheet-like member 51 so that the transparent protective member 56 provided in the opening 51H and the display panel 31 face each other.

  Further, the built-in device 18 is attached to the sheet-like member 51 so that the push button 38 and the sheet-like member 51 (the region where the name plate 37 of the sheet-like member 51 is formed) in the operation unit 36 face each other. In a state where the built-in device 18 is attached to (attached to) the sheet-like member 51, the periphery of the sheet-like member 51 is joined to the upper end portion 52 </ b> K of the case body 52.

  By the bonding, a hollow space 53 (see FIG. 2) in which the built-in device 18 (the thermistor 10, the control substrate 20, the display unit 30, the power supply unit 40, and the substrate 29) is sealed in a substantially airtight manner is formed. The built-in device 18 is sandwiched between the sheet-like member 51 and the case body 52 in the hollow space 53. The housing 50 is formed by mutual joining of the sheet-like member 51 and the case body 52.

  The sheet-like member 51 is disposed so as to face the dish-like accommodation region 60 with a gap so as to close (cover) the opening of the dish-like accommodation region 60 from the sheet-like member 51 side. As described above, the inside of the dish-shaped storage area 60 is preferably filled with an adhesive, a polystyrene foam (not shown), or the like so as to press the temperature sensing part 11 against the inner peripheral surface 60S of the dish-shaped storage area 60. .

  In order to join the sheet-like member 51 and the upper end portion 52K of the case body 52 to each other, the sheet-like member 51 and the upper end portion 52K of the case body 52 are arranged to face each other. In this state, ultrasonic waves are applied to the contact portion between the sheet-like member 51 and the upper end portion 52K. The sheet-like member 51 (such as a sealant layer) is temporarily dissolved by the applied ultrasonic waves. By the melting, the sheet-like member 51 is welded (crimped) to the upper end portion 52K of the case body 52. The sheet-like member 51 and the upper end portion 52K of the case body 52 may be joined by heat welding or an adhesive.

  As described above with reference to FIG. 3, the electronic thermometer 100 includes a temperature sensing unit 11, a control unit 22, a memory unit 23, a notification unit 24, a display unit 30, an operation unit 36, and a power supply unit 40.

The operation unit 36 may be provided on the control board 20 (may be attached to the control board 20 as a part of the control board 20).

  The temperature sensing unit 11 detects the body temperature of the measurement subject by being sandwiched between measurement target sites such as the armpit or the tongue. The operation unit 36 includes, for example, a push button 38 (see FIG. 1), receives an operation by a person to be measured (or a user of the electronic thermometer 100), and sends an external command to the control unit 22 or the power supply unit 40. input. The control part 22 is comprised from CPU (Central Processing Unit), for example, and controls the whole electronic thermometer 100. FIG.

  The memory unit 23 is constituted by, for example, a ROM (Read-Only Memory) or a RAM (Random-Access Memory), and stores a program for causing the control unit 22 to execute a processing procedure for measuring body temperature, and a measurement result. Or remember. The notification unit 24 is configured by a buzzer, for example, and notifies the measurement subject that the measurement has been completed or that the measurement subject's operation has been accepted. The alerting | reporting part 24 is good to be provided as needed.

  The display unit 30 includes a display panel 31 (see FIG. 1) such as an LCD (Liquid Crystal Display), for example, and displays measurement results and the like. The power supply unit 40 includes, for example, a button battery 42 (see FIG. 1) and supplies power as a power source to the control unit 22.

  The control unit 22 includes a processing circuit for performing body temperature measurement, and measures body temperature based on a program read from the memory unit 23. At that time, the control unit 22 calculates the body temperature as the measurement result by processing the temperature data input from the temperature sensing unit 11. The control unit 22 displays the calculated body temperature on the display unit 30, stores the calculated body temperature in the memory unit 23, or notifies the measurement subject that the measurement is completed using the notification unit 24. Next, the electronic thermometer 100 is controlled.

(Action / Effect)
Referring again to FIG. 1, the housing 50 of the electronic thermometer 100 is simply composed of a sheet-like member 51 and a case body 52. The sheet-like member 51 is an extremely thin member made of PET or the like. Since the sheet-like member 51 is thin and manufactured by cutting or the like, it can be prepared at low cost. Since the case body 52 is also an extremely thin member made of PET or the like by vacuum molding or the like, it can be prepared at a low cost. According to the electronic thermometer 100, the manufacturing cost can be reduced as compared with a general so-called pencil-type electronic thermometer in which the entire casing is made of molded resin.

  Since the electronic thermometer 100 is manufactured at low cost, the electronic thermometer 100 is suitable for being used as a so-called disposable type. If it is a disposable type, it is discarded every time the electronic thermometer 100 is used (or every predetermined number of times of use), for example, at a medical site. According to the electronic thermometer 100, it is possible to reduce the cost burden on the user side or the person to be measured that occurs at each disposal.

  In the electronic thermometer 100, the annular wall portion 52U and the upper end portion 52K of the case body 52 are opened toward the side where the built-in device 18 is accommodated in the unidirectional direction with respect to the case body 52. Forming. The internal device 18 (or the internal device 18 attached to the sheet-like member 51) can be easily assembled in one direction with respect to the case body 52 that forms the opening.

  Also in the dish-shaped storage area 60, an opening is formed toward the side where the temperature-sensitive part 11 is stored so that the temperature-sensitive part 11 can be stored in one direction with respect to the dish-shaped storage area 60. The temperature sensing unit 11 can be easily assembled in one direction with respect to the dish-shaped accommodation region 60. The sheet-like member 51 can also be easily disposed opposite to the dish-like accommodation region 60 in which the temperature sensing unit 11 is assembled.

  Therefore, when the electronic thermometer 100 is mechanically assembled, the operation direction of an automatic machine or the like used for assembling the electronic thermometer 100 is simplified. According to the electronic thermometer 100, it can be assembled more efficiently (compared to the conventional electronic thermometer), and the manufacturing cost can be further reduced.

  From the viewpoint of efficient assembly, the sheet-like member 51 as the first housing and / or the case body 52 as the second housing are, for example, resins made of ABS resin (Acrylonitrile-Butadiene-Styrene copolymer synthetic resin). You may comprise as a molded article. In this case, the dish-shaped storage area 60 is preferably formed integrally with the case body 52.

  As shown in FIG. 1, in the present embodiment, a dish-shaped storage area 60 is provided in the case body 52. The dish-like storage area 60 may be provided in the sheet-like member 51. In this case, the case body 52 constitutes the first housing in the present invention, and the sheet-like member 51 constitutes the second housing in the present invention. Even if it is the said structure, the effect | action and effect similar to the electronic thermometer 100 in this Embodiment can be acquired.

  As described above with reference to FIG. 2, the temperature sensing unit 11 is accommodated inside the dish-shaped storage area 60. A part of the outer peripheral surface of the temperature sensing unit 11 is in contact with the inner peripheral surface 60S of the dish-shaped accommodation region 60 at the contact portion P1. The body temperature of the person to be measured is easily transmitted to the temperature sensing unit 11 through the dish-shaped storage area 60. According to the electronic thermometer 100, it is possible to improve the response speed of the temperature sensing unit 11 and improve the measurement accuracy when measuring the body temperature.

  Further, the remaining portion of the outer peripheral surface of the temperature sensing unit 11 is separated from the inner peripheral surface 60 </ b> S of the dish-shaped storage region 60 with an interval S <b> 1. When the electronic thermometer 100 is mechanically assembled, the temperature sensing unit 11 can be easily and reliably accommodated in the dish-shaped accommodation region 60.

  In the present embodiment, the bottom 60T of the dish-shaped storage area 60 is formed flat. Even if the contact position (position of the contact portion P1) with respect to the dish-shaped accommodation region 60 (on the bottom portion 60T) of the temperature sensing unit 11 has an error due to manufacturing reasons, the influence on the measurement performance of the electronic thermometer 100 is reduced. can do. Further, since the bottom 60T is formed in a flat shape, a sense of incongruity to the measurement subject during body temperature measurement can be alleviated.

With reference to FIG. 4, the electronic thermometer 101 in the 1st modification of the above-mentioned embodiment is demonstrated. FIG. 4 is a cross-sectional view showing the electronic thermometer 101. FIG. 4 substantially corresponds to FIG. 2 in the above-described embodiment. In FIG. 4, a sheet-like member 51 as a first housing and a case body 52 as a second housing are each formed in a substantially U shape in a sectional view. As described above, the sheet-like member 51 as the first housing and the case body 52 as the second housing may be resin molded products.

  In the electronic thermometer 101, a reinforcing rib 61 (first reinforcing rib) extending toward the sheet-like member 51 is provided in the dish-shaped accommodation region 60. The reinforcing rib 61 may extend in a direction perpendicular to the bottom portion 60 </ b> T of the dish-shaped accommodation region 60. The reinforcing rib 61 may be molded integrally with the dish-shaped storage area 60, or may be molded as a separate body and then joined to the dish-shaped storage area 60.

  The reinforcing rib 61 may be formed in a rod shape, or may be formed in a flat plate shape having a predetermined width in the direction perpendicular to the paper surface of FIG. The reinforcing ribs 61 may be arranged symmetrically so as to face each other with the lead wire 12 interposed therebetween so as not to obstruct the wiring path of the lead wire 12.

  When measuring the body temperature or transporting the electronic thermometer 101, an unexpected external force may act toward the dish-shaped storage area 60 or the temperature-sensitive part 11 stored in the dish-shaped storage area 60 (arrow AR101). reference). The external force is generated, for example, when the tip of the electronic thermometer 101 is bitten by teeth when the electronic thermometer 101 is inserted into the mouth. In particular, when the housing 50 (the sheet-like member 51 and the case body 52) is simply configured, the temperature-sensitive part 11 is damaged by the external force, or the shape of the dish-shaped accommodation region 60 is deformed.

  Even if the external force acts toward the dish-shaped storage area 60 or the temperature sensing part 11 stored in the dish-shaped storage area 60, the reinforcing rib 61 provided in the dish-shaped storage area 60 is not affected by the external force. Oppose. The breakage of the temperature sensing unit 11 or the shape deformation of the dish-like storage area 60 can be suppressed or prevented. When the reinforcing rib 61 is formed in a flat plate shape, the electronic thermometer 101 may be disposed so as to be perpendicular to the direction of the teeth (front teeth) when the electronic thermometer 101 is inserted into the mouth. The breakage of the temperature sensing unit 11 or the shape deformation of the dish-shaped storage area 60 can be further suppressed or prevented.

  In the electronic thermometer 102, a reinforcing rib 62 (second reinforcing rib) extending toward the dish-shaped accommodation area 60 is provided on the inner surface 51 </ b> S of the sheet-like member 51 facing the dish-shaped accommodation area 60. The reinforcing ribs 62 may extend in a direction perpendicular to the inner surface 51S of the sheet-like member 51. The reinforcing rib 62 may be molded integrally with the sheet-like member 51, or may be joined to the sheet-like member 51 after being molded separately.

  The reinforcing ribs 62 may be formed in a rod shape, or may be formed in a flat plate shape having a predetermined width in the direction perpendicular to the paper surface of FIG. The reinforcing ribs 62 are preferably arranged symmetrically so as to face each other with the lead wire 12 interposed therebetween so as not to disturb the wiring path of the lead wire 12.

  Similar to the reinforcing rib 61 in the first modified example described above, even if an unexpected external force acts toward the dish-shaped storage area 60 or the temperature-sensitive part 11 stored in the dish-shaped storage area 60, the sheet-shaped member The reinforcing rib 62 provided in 51 opposes the external force. The breakage of the temperature sensing unit 11 or the shape deformation of the dish-like storage area 60 can be suppressed or prevented.

  As shown in FIG. 6, in the electronic thermometer 103, guide ribs 63 that extend toward the dish-shaped accommodation area 60 are provided on the inner surface 51 </ b> S of the sheet-like member 51 that faces the dish-shaped accommodation area 60.

  As shown in FIG. 7, the guide rib 63 is provided so as to hang from an inner surface 51S (not shown) of the sheet-like member 51 in a direction perpendicular to the inner surface 51S. The guide rib 63 is configured in a substantially flat plate shape, and extends in a direction perpendicular to the wiring direction of the lead wire 12 in the hollow space 53 (a direction perpendicular to the paper surface of FIG. 6).

  In addition to the guide rib 63, the electronic thermometer 103 is also provided with the reinforcing rib 62 in the second modification described above. The electronic thermometer 103 may be provided with only the guide rib 63 alone.

  When the electronic thermometer 103 is assembled, the guide rib 63 approaches (in one direction) from above the lead wire 12 toward the lead wire 12. By arranging the guide rib 63 at a predetermined position, the lower end 63T of the guide rib 63 comes into contact with the lead wire 12. The contact between the lower end 63T and the lead wire 12 causes a frictional resistance between the lower end 63T and the lead wire 12, and the position of the lead wire 12 is guided by the lower end 63T of the guide rib 63. The lower end 63T may be formed in a concave shape so that the arrangement position of the lead wire 12 can be easily guided.

  The lower end 63T of the guide rib 63 may be configured to press the lead wire 12 against the inner peripheral surface 60S of the dish-shaped storage area 60 with a predetermined pressing force. By positioning the lead wire 12, the position shift of the temperature sensing unit 11 is suppressed, and the measurement accuracy is improved.

  Further, in the electronic thermometer 103, two reinforcing ribs 62 are provided so as to sandwich the lead wire 12 from both sides. Each reinforcing rib 62 restricts the movement of the lead wire 12 in the width direction (the direction perpendicular to the plane of FIG. 6). The arrangement position of the lead wire 12 can also be guided by the reinforcing rib 62.

[Fourth Modification]
With reference to FIG. 8, the electronic thermometer 104 in the 4th modification of the above-mentioned embodiment is demonstrated. FIG. 8 is a cross-sectional view showing the electronic thermometer 104. FIG. 8 substantially corresponds to FIG. 2 in the above-described embodiment.

  The electronic thermometer 104 is configured so that the lead wire 12 has a predetermined elasticity (rigidity). The lead wire 12 is disposed in a cantilever shape. The elasticity (rigidity) of the lead wire 12 may be realized by selecting the material of the lead wire 12, or may be realized by twisting the lead wire 12 in a spiral shape, for example. As shown in FIG. 8, the control board 20 may be provided on the lower surface side of the board 29 with respect to the board 29 (the side opposite to the mode shown in FIG. 1). The lead wire 12 is connected to the control board 20 so as to stand up from the control board 20 toward the dish-shaped storage area 60.

  By arranging the lead wire 12 in a cantilever shape so as to stand up from the control board 20 toward the dish-shaped accommodation area 60, the temperature sensing unit 11 applies a predetermined pressing force (with respect to the dish-shaped accommodation area 60 ( Pressed by elastic force). The contact pressure with respect to the dish-shaped accommodation area | region 60 of the temperature sensing part 11 becomes high, and the improvement of the response speed of the temperature sensing part 11 at the time of body temperature measurement and the improvement of a measurement precision can be aimed at. Further, the lead wire 12 is easily positioned by the elasticity (rigidity) of the lead wire 12. The positional deviation of the temperature sensing unit 11 is suppressed, and the measurement accuracy as the electronic thermometer 104 is improved.

[Fifth Modification]
With reference to FIG. 9 and FIG. 10, the electronic thermometer 105 in the 5th modification of the above-mentioned embodiment is demonstrated. FIG. 9 is a side view (partially a cross-sectional view) showing the electronic thermometer 105. 10 is a cross-sectional view taken along line XX in FIG.

  As shown in FIG. 9, in the electronic thermometer 105, the control board 20 is comprised of a surface mount type board. The substrate 29 extends to the upper side of the dish-shaped accommodation area 60, and the control board 20 is provided below the tip in the extending direction of the substrate 29 (on the dish-shaped accommodation area 60 side). The temperature sensing unit 11 in the thermistor 10 is directly mounted on the surface of the control board 20. Here, the lead wire 12 is composed of a fine metal terminal. According to the said structure, thickness reduction of the housing 50 in the plate-shaped accommodation area | region 60 vicinity can be achieved.

  In order to reduce the thickness, the control board 20 may be disposed at another position, and the temperature sensing unit 11 may be directly mounted on the surface of the board 29. In this case, the temperature sensing unit 11 and the control board 20 arranged at another position are electrically connected through the board 29. A step 65 may be provided near the tip of the housing 50. The step 65 makes it possible to suppress excessive insertion when the electronic thermometer 105 is inserted, for example, under the tongue.

  Referring to FIG. 10, the temperature sensing unit 11 may be configured to be pressed with a predetermined pressing force (elastic force) against the dish-shaped accommodation region 60 by the elasticity of the substrate 29 or the control substrate 20. . According to the electronic thermometer 105, since the thermistor 10 is directly mounted on the control board 20, a positional shift of the temperature sensing unit 11 with respect to the dish-shaped accommodation region 60 is unlikely to occur. It is possible to improve the response speed and the measurement accuracy of the temperature sensing unit 11 when measuring the body temperature.
