Further, a switch is provided at a position where the operability is further improved, so that the DC power supply from the battery to the inverter unit can be intermittently performed.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be specifically described below based on an embodiment shown in the drawings. FIG. 1 is an exploded perspective view showing an embodiment of the present invention. In the figure, reference numeral 2 denotes a triangular scale main body of a light transmissive material triangular prism hollow cylindrical body having appropriate rigidity. On each surface (three surfaces) of the triangular scale body in the long side direction, detailed scales for measurement, numbers, symbols and the like are written in a non-light-transmissive material. Further, a sheet-shaped E light emitter product 1 is mounted inside the hollow cylindrical body portion to form a light emitting portion 4. Further, an electric circuit section 3 described later is built in a part of the inner side of the EL light emitting member 1. Reference numeral 5 denotes an opening / closing lid portion for maintenance such as battery replacement of the electric circuit portion 3. Inside thereof, a switch SW which is operable from the outside to turn on / off a predetermined portion of the electric circuit portion of the electric circuit portion 3 is provided. Has been.

FIG. 2 shows an electrical circuit relationship between the electrical circuit section 3 and the EL light emitting product 1. The electric circuit unit 3 includes a battery 6, an inverter circuit unit 7 to which power is supplied from the battery 6, and a previous period switch SW that connects and disconnects the power supply. The inverter circuit unit 7 is a circuit unit that obtains DC power from the battery 6, boosts it, converts it to AC, and sends it out. The EL luminous body product 1 is a sheet-shaped luminous product that emits light by the electroluminescence phenomenon when an alternating current is applied from the inverter circuit section 7, and is mounted inside the triangular scale body 2 as in the previous term.

In the triangular scale body 2 as described above, DC power is applied from the battery 6 to the inverter circuit section 7 by turning on the switch SW, whereby the inverter circuit section 7 applies alternating current to the EL light emitting body 1, The EL light emitter product 1 emits light. The light emission is stopped by turning off the switch SW.

FIG. 3 is a perspective view of the product at the time of completion showing an embodiment of the present invention. As described above, reference numeral 2 denotes a triangular scale main body formed of a light transmissive triangular prism hollow cylindrical body having appropriate rigidity. Reference numeral 4 denotes a light emitting part. An opening / closing lid 5 for maintenance is removable. SW designates a switch which is operated from the outside to turn on and off a required portion of the electric circuit portion. Reference numeral 8 denotes a triangular scale measurement surface.

FIG. 4 is a perspective view of a product showing a conventional technique. In the figure, 8 indicates a measurement surface.

The scope of the present invention is not limited to the above embodiment, and various details are possible.
For example, for the power supply to the EL light emitter product 1, the DC power from the battery 6 is replaced by an inverter circuit, and DC /
By using a DC converter circuit, the DC power source obtained by this, or the DC power source from the above-mentioned battery may be directly applied to the EL light emitting product (however, in these cases,
It is necessary to make the type of EL light emitting product that emits light in response to the application of a DC voltage). In addition, E of the EL light emitting product itself
If the L-element coating material has appropriate rigidity, the surface of the L-element coating material can be directly marked for measurement, and can also serve as the cover portion. At that time, the main body is not limited to a hollow cylindrical state. . In addition, the surface of the triangular scale can be designed in various ways, and the triangular scale product can have an unprecedented aesthetic appeal. EL
The color tone of the luminous body product 1 can be freely selected. In addition, depending on the material of the EL EL light emitting product (using organic EL), one EL light emitting product may be provided with a color tone switching device, so that several kinds of color tones can be selected. It is also possible to have different color tones on the light emitting portions on each of the three sides of the triangular scale.
Regarding the notation of the measurement surface, which is the light emitting unit of the triangular scale, only the notation can be made to emit light if the notation portion is made of a light transmissive material and the other portions are made non-light transmissive.

As described above, according to the present invention,
By using the measurement triangular scale of the present invention even in a dim place such as a room, since the measurement surface is a light emitting portion, the detailed scale, numbers, symbols, etc. written on the measurement surface become clear as appropriate, Convenience such as measurement work is enhanced, and improvement of work efficiency can be expected. It also serves as an indicator in the dark, such as during a power outage. In addition, since the product of the present invention emits light beautifully in terms of design, it is expected that measurement work can be enjoyed. If a blue-based color tone that is particularly easy on the eyes is adopted, the effect of suppressing eye fatigue during measurement work can be achieved. Can be expected. As described above, the triangular scale for measurement of the present invention provides not only measurement but also various excellent effects.
