In recent years, with the development and spread of diving equipment, the number of divers, both professional and amateur, has been rapidly increasing. In particular, with the advent of high-precision depth gauges using silicon diaphragm pressure sensors, further development is expected in the future. However, this high-precision depth gauge is difficult to maintain after use, especially since it is used in seawater.If it is left unused, salt may crystallize and block the pressure inlet hole, or sand and dirt may accumulate. There is a risk of damaging the sensor if it is used with the water inside, and unless this point is improved, this high-precision depth gauge will not become widespread in the future. Therefore, in order to solve this problem, we devised a structure for introducing external pressure from the outside of the pressure sensor.

に特殊な工具を必要とした。 Japanese Patent Application Laid-Open No. 59-159084 was developed as a structure for the pressure introduction part from the outside of the pressure sensor of the conventional electronic watch with depth gauge.
As shown in FIGS. 5 to 8 of the embodiment of the publication,
One example is a structure in which a cover plate with small holes is fixed to the pressure introduction part of the pressure sensor. However, with this structure, if the cover plate was not exposed on the front of the watch body, it was not possible to remove the cover and clean the sensor pressure introduction hole, resulting in design constraints and the need for special tools to remove the cover plate. .

From the above points, the pressure introduction hole is covered with a cover plate exposed at the front, which was a problem in the past, and the user cannot operate the pressure introduction hole without using a special jig etc. The aim is to eliminate the design of the cover plate for the sensor part, which seems to have been attached to the original, and create a design that is both clear and expressive of the pressure introduction hole. The purpose is to be able to operate it.

ている。 In FIG. 1, 1 is a pressure sensor, and a silicon diaphragm 1b is fixed to a sensor mounting base 1a, and wired to a substrate 1c. 1e is a protection frame that protects the sensor. 1d is a protective agent that protects the silicon diaphragm 1b from seawater and the like. This pressure sensor 1 is a general semiconductor type pressure sensor. In particular, the main text does not make any statements about driving principles, etc. 2 is the outer case and pressure sensor 1
The pressure sensor 1 is positioned through a gasket 3 through a mounting hole 2a. Packkin 3 also provides waterproofing between pressure sensor 1 and exterior case 2. 2b is an external pressure introduction hole provided in the exterior case 2. Reference numeral 4 denotes a conduction spring that electrically connects the circuit of the watch body and the pressure sensor 1. 5 is
The cover covers the surface of the exterior case 2 and screws 6
is fixed to the exterior case. Further, a small hole 5a is provided in the cover 5 at approximately the same position as the sensor 1.

ともあり外観上も問題であつた。 In FIG. 3, after diving, the user first washes the cover plate 7 with water, then rotates the cover plate 7 with a special tool provided by the manufacturer and removes it from the outer case 2.
After cleaning sand, dirt, and salt adhering to the top surface of the pressure sensor 1 and the pressure introduction part, the cover plate 7 is attached to the outer case 2 again using a special tool. This was conventional work. In this case, the disadvantage is that the cover plate 7 cannot be rotated without first using a special tool, and if the tool is not available, the user may try to rotate it with tweezers etc. There is also a risk of damaging the protective agent 1d. Further, when the cover plate 7 is rotated, the area around the small hole 7a of the cover plate 7 may be damaged, which is a problem in terms of appearance.
更に第４図に示すようにカバー板７が時計体の
前面に露出してしまい決して外観のよいものでは
なかつた。 Furthermore, as shown in FIG. 4, the cover plate 7 was exposed at the front of the watch body, which did not give it a good appearance.

をはずせば簡単にとれ掃除も短時間ですむ。 While the conventional structure has the drawbacks mentioned above,
In the structure of the present invention shown in Fig. 1, since the cover 5 covers the entire surface of the watch case 2, the watch body will not be damaged even if it hits a rock or the like during diving, and it will not damage the watch body and prevent cuts on the watch body. There will be no more accidents. Furthermore, when the user cleans the pressure introduction hole, use a screwdriver to tighten screw 6.
It can be easily removed and cleaning can be done in a short time.
また、カバー５はウレタンゴム等の材質がよく
加工費も安く外観も良いものができる。 Further, the cover 5 can be made of a material such as urethane rubber, which is inexpensive to process, and has a good appearance.
