Electronic thermometer and method for manufacturing the same

First Embodiment

[0045]FIG. 1 is a perspective view of an external structure of an electronic thermometer 1 according to a first embodiment of the present invention, and FIG. 2 is a diagram showing a configuration of functional blocks of the electronic thermometer 1 shown in FIG. 1. First, the overall configuration of the electronic thermometer 1 of the present embodiment will be described with reference to FIGS. 1 and 2.

[0046]As shown in FIG. 1, the electronic thermometer 1 of the present embodiment includes a main housing 10, a cap 15 that forms a temperature measuring unit, and an obstructing member 16. The main housing 10 is a tubular hollow member made of a resin material such as ABS (acrylonitrile butadiene styrene) resin. The main housing 10 has a faceplate affixed at a predetermined position on its top face, and also has a display unit 4 and an operation unit 5 at predetermined positions on its top face. The cap 15 is a bottomed tube-shaped member, one end of which is obstructed

Second Embodiment

[0088]FIG. 9 is a perspective view of the internal structure of the electronic thermometer 1 according to a second embodiment. FIG. 10 is a cross-sectional view of the internal structure of the electronic thermometer 1 according to the second embodiment. The electronic thermometer 1 of the second embodiment is different from the above-described first embodiment in that the sub-case 50 of the assembly 18 extends toward the tip portion 11 side of the main housing 10 to form the extension portion 20.

[0089]Specifically, in the second embodiment, the buzzer cover 66 is formed so as to have a shape of covering the buzzer 65, and is housed inside the sub-case 50. The extension portion 20 is formed so as to extend from an outer side face of the front end portion of the sub-case 50 in the lengthwise direction. The extension portion 20 is a resin molded part, which is molded integrally with the sub-case 50 made of a resin material that is included in the assembly 18. On the exte

Third Embodiment

[0093]FIG. 11 is a plan view of the arrangement of the extension portion 20 and the lead 72 according to the third embodiment. FIG. 12 is a cross-sectional view of the extension portion 20 according to the third embodiment taken along line XII-XII shown in FIG. 11. As shown in FIGS. 11 and 12, a through-hole 30 that pierces the extension portion 20 in the thickness direction is provided in the extension portion 20 of the third embodiment. The through-hole 30 is formed so as to extend along the extending direction of the extension portion 20. The lead 72 is arranged so as to extend beyond the through-hole 30.

[0094]As shown in FIG. 12, the fixing material 41 of the third embodiment is provided on the top face 21 of the extension portion 20 at a position on the projecting end 26 side relative to the through-hole 30. The fixing material 41 is arranged at a position that opposes the base part where the extension portion 20 projects from the assembly 18, with the through-hole
