Problems solved by technology

In order to improve operability, it is required to make the fixed part case 4 and the moving part case 5 as thin as possible to reduce the weight. Due to the disconnection caused by using a thinner flexible wiring material to relax the bending stress, it is necessary to expand the width of the wiring. Since the wiring width of the electrical wiring routed to the moving part housing 5 is enlarged, there is a problem that the electric vacuum cleaner cannot be reduced in weight. topic

Embodiment Construction

[0042] Hereinafter, the display lighting device of the present invention will be described based on the embodiments.

[0043] Figure 15 An electric vacuum cleaner equipped with the display lighting device of the present invention is shown.

[0044] It should be noted that, for Figure 16 The same constituent elements are described using the same reference numerals.

[0045] In this electric vacuum cleaner, the suction force is generated by the motor of the vacuum cleaner main body 1, and the manual operation part 3 at the front end of the hose 2 connected to the vacuum cleaner main body 1, the fixed part housing 4 as the extension pipe of the fixed part, and the The hollow part connected in series such as the moving part case 5 and the suction nozzle 6 of the extension pipe sucks dust and dust.

[0046] The fixed part case 4 and the moving part case 5 are made of opaque materials. A light source unit 7 is disposed near the front end of the fixed portion case 4 . The light...

Abstract

An indication lighting device provided is capable of reducing the number of electric wiring from a fixed, part to a moving part when an indication part is provided in the moving part's side. The indication lighting device makes indication by emitting light from a light source arranged in a fixed part to an optical waveguide arranged in a moving part, reflecting the light incident on the optical waveguide by reflection surfaces of prisms of the optical waveguide to an indication part provided in a tip side of the optical waveguide to be propagated, and emitting the light propagated inside the optical waveguide through the indication part.

Description

technical field [0001] The present invention relates to a display and lighting device incorporated in an electrified product, etc., which has a mechanism part in which the position of a moving part relative to a fixed part can be locked at a plurality of stop positions. Background technique [0002] An electric vacuum cleaner can be mentioned as an example of an electrified product having a mechanism in which the position of the moving part relative to the fixed part can be locked at a plurality of stop positions. It is described in Patent Document 1 that Figure 16 Electric vacuum cleaner shown. [0003] The cleaner main body 1 is provided with a motor for generating force to attract dust and dust. The vacuum cleaner main body 1 and the suction nozzle 6 are connected via a flexible hollow hose 2 and an extension pipe composed of a fixed part case 4 and a moving part case 5. The fixed part case 4 and the moving part case 5 is hollow, and transmits the suction force of the ...
