DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display thermometer.

[0002]

2. Description of the Related Art In recent years, an electronic thermometer having a liquid crystal display has advantages such as accurate measurement in a short time and easy reading of body temperature.
It is increasingly used in place of mercury-type thermometers.

[0003] In a conventional electronic thermometer, since a liquid crystal display panel without a backlight is used, reading of body temperature cannot be performed unless there is external light. However, the measurement environment of the body temperature is not always a bright place, and is often performed in a dark place, for example, at night. In such a case, the conventional liquid crystal display thermometer cannot read the measured body temperature accurately, and has a problem that the measurement environment must be a bright place sufficient for reading.

On the other hand, in a general liquid crystal display device,
In order to solve the above-described reading problem, an EL (electroluminescence) panel is provided as a backlight. By installing the backlight in this manner, an image or the like displayed in a dark place can be read, and the viewing angle can be increased.

[0005] However, since the electronic thermometer itself is small, even if it is possible to install an EL panel or the like as a backlight, the power supply and circuit for driving the EL panel are not compatible with current electronic thermometers. It cannot be mounted on a thermometer. In addition, in order to mount a power supply or a circuit for driving the EL panel, the electronic thermometer itself must be increased in size, and the measuring function and handling properties are reduced due to an increase in weight and the like.

[0006]

As described above, the conventional electronic clinical thermometer having a liquid crystal display has a drawback that the operating environment is limited such that the displayed body temperature cannot be read in a dark place. Was.

[0007] The present invention has been made to address such a problem, and without increasing the size of the thermometer itself,
It is an object of the present invention to provide a liquid crystal display type thermometer device capable of accurately reading a displayed body temperature even in a dark place or the like.

[0008]

SUMMARY OF THE INVENTION A liquid crystal display thermometer device according to the present invention has a liquid crystal display section for displaying a body temperature measured by a body temperature measurement section, and has a lighting lead for a backlight having a lead out to the outside. An EL panel has a liquid crystal display thermometer installed below the liquid crystal display section, and a storage section for the liquid crystal display thermometer, and a drive power supply and a drive circuit for the EL panel are provided therein. A terminal connected to an EL panel driving circuit includes a thermometer storage case drawn out into the storage section, and when the liquid crystal display thermometer is mounted in the thermometer storage case, the backlight EL panel is It is characterized in that it is illuminated.

[0009]

In the liquid crystal display thermometer device of the present invention, since the driving power supply and the driving circuit of the EL panel are installed on the thermometer housing case side, it is not necessary to enlarge the liquid crystal display thermometer itself, and the measurement function and There is no loss of handling. Then, when the liquid crystal display thermometer after measuring the body temperature is mounted in the thermometer storage case, the lead of the EL panel on the thermometer side and the terminal on the drive circuit side are electrically connected, so that the EL panel is turned on. Therefore, it is possible to accurately read the displayed body temperature even in a dark place or the like after the measurement of the body temperature.

The thermometer 1 has a measuring circuit 3 and a display circuit 4 connected to the body temperature measuring unit 2 and a liquid crystal display unit 5 connected to the thermometer 1 so that the display surface thereof faces forward. is set up. Although not shown, a battery is housed in the thermometer 1 as a power source for driving the measurement circuit 3, the display circuit 4, and the liquid crystal display unit 5.

An EL panel 6 is disposed below the liquid crystal display section 5 as a backlight. The lighting leads 7 of the EL panel 6 are drawn out to the bottom side of the thermometer 1 and can be connected from the outside.

The liquid crystal display thermometer 1 having such a configuration measures the temperature in the same manner as a normal electronic thermometer, and then, as shown in FIG. 4 and FIG. Be attached. That is, the liquid crystal display thermometer device of this embodiment is constituted by the liquid crystal display thermometer 1 and the thermometer storage case 8.

The thermometer storage case 8 has a storage section 9 for the thermometer 1, and a drive power supply 10 and a drive circuit 11 for the EL panel 7 are installed therein. The EL panel drive power supply 10 is configured by a detachable battery. Drive circuit 11 for EL panel
Are connected to the storage section 9 respectively.
And is provided so as to be electrically connected to the EL panel lighting leads 7 on the thermometer 1 side when the thermometer 1 is mounted in the storage section 9. When the liquid crystal display thermometer 1 is mounted on the thermometer storage case 9, the EL panel drive circuit terminals 12, 12 on the storage case 9 side and the EL panel lighting leads 7, 7 on the thermometer 1 side are electrically connected. The backlight EL panel 6 is connected so as to be turned on. The EL panel 6 is turned on only for a predetermined time by a timer circuit incorporated in the drive circuit 11.

Next, a method of using the liquid crystal display thermometer device having the above-described configuration will be described.

First, the thermometer 1 is taken out of the thermometer storage case 8, and the body temperature is measured in the same manner as a normal electronic thermometer. After the measurement of the body temperature is completed, the measured body temperature is displayed on the liquid crystal display unit 5 of the thermometer 1. However, at this stage, as with the conventional thermometer, the displayed body temperature can be read only in a light place where external light exists.

Therefore, a thermometer 1 on which the measured body temperature is displayed.
Is attached to the storage section 9 of the thermometer storage case 8. When the thermometer 1 is mounted, the EL panel drive circuit terminals 12 on the storage case 8 side are electrically connected to the EL panel lighting leads 7 on the thermometer 1 side, and the backlight EL panel 6 is turned on. I do. By turning on the backlight EL panel 6, the displayed body temperature can be read accurately even when the body temperature measurement environment is a dark place or the like.
