Description

[Detailed Description of the Invention] The present invention relates to a diving watch that measures and displays other physical quantities such as time, temperature, and pressure at the same time as the time.

Conventionally, there has been no display device that can clearly recognize the time and time at the same time, and various hybrid timekeeping devices have been considered that combine a digital display with an LCD device and an analog display with hands.
Even when measuring time simply by dotting the dots in a dual-time manner, the digital display of numerical segments is undesirable for instantaneous recognition of elapsed time or remaining time, and has the drawback of poor readability. In addition, in order to make the digital display readable underwater in a dark environment, it is necessary to use a lighting device over a wide range or a display device that displays all numeric segments using self-luminous display elements. Since a large amount of current is consumed when the lamp is turned on for a certain period of time, it has been difficult to realize it in a size suitable for a portable watch.

The purpose of the present invention is to provide a diving watch that allows extremely important diving information to be viewed even in the dark and that does not cause erroneous readings.
At the same time, it realizes lower power consumption.

To explain the present invention with reference to the drawings, in the embodiment shown in FIG. 1, 1 is a display section, and the time display section 1a is composed of a liquid crystal display panel, which displays hours, minutes, and seconds in a digital display using ordinary 7-segment numbers. Display the year, month, day, etc. on the back channel.

For display contents other than time, 1b is EL
When used as a diving watch with an electroluminescence display, the diving depth display section displays the depth in a fan-shaped graph. The DEPTH, depth, and m display marks are permanently displayed by printing on the EL panel, and the measuring device has an electrical resistance in the center of the back cover of the measuring device case in response to mechanical strain such as a piezoelectric element. By attaching and fixing elements whose electrical characteristics change, such as the following, pressure changes depending on the diving depth are detected by the deflection of the back cover, and the measurement is displayed using the movement's electronic circuit.

Section 1c is an analog temperature display section using a needle-shaped EL display. Similar to section 1d, the TEMP. and °C display marks are printed on the EL panel, and the measuring device is a thermistor. The EL display is performed using a conventionally known measurement device that electrically measures temperature using a heat-sensitive element such as a critegister. Other measurement display parts, such as the elapsed time display part 1d and the direction display that is electrically detected and displayed using an electronic circuit configuration using the magnetic sensor 1e, also have the same fan-shaped EL display or needle-shaped EL display as described above. It is displayed so that it can be read simultaneously and distinguished from the digital time display. Even when multiple types of displays are displayed at the same time as in this embodiment, each display amount can be instantly recognized by angular recognition of the fan-shaped graph display, so a measuring device with good readability can be obtained even in a multi-function watch. be. Fan-shaped segment or needle-shaped segment by EL is 5m or 5
℃ and in units of 5 minutes, measurement accuracy will be improved if the time is further divided and displayed. The diving information display section includes a diving depth display section 1b and an elapsed time display section 1d. Since the diving depth display section 1b and the elapsed time display section 1d are arranged at different positions above and below the time display section 1a, it is impossible to mistake the two display sections even when it is dark during a dive.

Fig. 2 shows an analog representation of the fan-shaped graph described above using a bar graph.The diving depth display section 2b is displayed as a bar graph at intervals of 5 m, and the temperature display section 2c has + and - sides. The temperature is divided into left and right by the TEMP. display mark, and a bar graph is displayed every 5 degrees Celsius. Measurement accuracy will improve if the EL bar segments in the bar graph are displayed in further subdivisions, rather than in 5m or 5°C units. The EL display section of the bar-shaped segment of the day of the week display section of 2d displays the day of the week using two regular bar-shaped segments, and when the MODE is switched, the elapsed time is displayed in bar graph form in 5-minute increments. The number of rod-shaped segments in the EL panel has been reduced and streamlined.

Reference numeral 2e denotes a mode switching display section, which displays the mode. In addition to self-luminous display using an EL panel, self-luminous elements such as light emitting diodes may also be used.

This bar-shaped segment display can be used to display two or more types, and the bar-shaped EL segment can only be displayed in one row.
It is also possible to switch the display of time, temperature, diving depth, etc. by switching the MODE. 2F is a warning light that can be visually recognized along with an alarm sound when the dive time approaches a predetermined allowable time, and is configured so that it can be clearly recognized even in a dark environment by using self-luminous display elements such as light emitting diodes. has been done.

In this way, the time display section 2a using the liquid crystal display element
Other than that, the bar graph-like analog display using bar-shaped EL segments is used individually or as a switchable display, making it easy to distinguish between the time display and other displays, resulting in a multifunctional measurement display device with good readability. It is something.

The bar-shaped diving depth display section 2b, elapsed time display section 2d, and warning light 2f in FIG. Since the marks have different shapes and sizes, they can be clearly read even in dark environments such as underwater, which is very effective for diving watches. Also, in the fan-shaped graph display as shown in Figure 1, two or more types of display other than time can be selectively displayed by switching MODE.
Display content marks such as mm and m are not permanently displayed on the EL panel, but are switched and displayed on the EL display by switching MODE. In addition, the time display part may be not only a 7-segment number display but also a dot segment number display of about 5 x 7. In the case of a dot segment, the time display part can be a number display part, a dot display, or an analog display of a bar-shaped display. The streamlined display is highly effective, as measurement displays such as time and temperature can be switched on the same display. Further, if the display method, shape and size of the display mark are changed for each display content such as temperature and depth, it is possible to improve the discriminability.

As explained above, in the diving watch using the display method of the present invention, the time is displayed digitally in the display section, and the diving information other than the time, such as the diving time and diving depth, is displayed in an analog format such as a fan graph or a bar graph. By using a novel configuration that allows simultaneous display or selective display, it is possible to obtain a rational diving watch that is highly readable and can be made at low cost. Furthermore, dive information such as dive time, remaining time, and dive depth is displayed by self-luminescence, and in addition, each dive information section is different in at least one of the display format, the shape of the display mark, and its size. Even in dark water during a dive, it is possible to reliably view the above-mentioned diving information, which is extremely important for a diving watch, and it has been possible to dramatically improve the safety of the diver. on the other hand,
Since the time display section with a large display area is constructed from a liquid crystal display element, power consumption can be minimized.
