JPH01180429A - Color luminance meter with automatic suction type photodetecting part - Google Patents

Abstract

PURPOSE:To improve the setting property of a photodetecting part by providing a vacuum suction pad to the photodetecting part so that the photodetecting part can be attached to and detached from the surface of an image receiving tube by control of a vacuum generator. CONSTITUTION:This color luminance meter is constituted of a measuring instrument body and the photodetecting part 2. The automatic suction type photodetecting part 2 is constituted of the vacuum suction pad part 8, the photodetecting part body 7 and a switch 11 for controlling the attachment and detachment. An automatic suction control circuit consists of the vacuum generator 13 for evacuating the inside of the suction pad 3 and a solenoid valve 14 and a power supply 15 for electrical control of compressed air. The compressed air flows to the vacuum generator 13 and the inside of the suction pad 3 is evacuated to a vacuum when the photodetecting part 2 is positioned to the surface of a cathode ray tube and the switch 11 for controlling the attachment and detachment is turned on at the time of attaching or detaching the photodetecting part 2 to and from the cathode ray tube. The photodetecting part 2 is then set to the surface of the cathode ray tube. The compressed air is stopped and the photodetecting part 2 is detached from the cathode ray tube when the switch 11 is turned off. The setting property of the photodetecting part is thereby improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a color luminance meter that contacts the surface of a picture tube, and more particularly, to a color luminance meter that can automatically attach and detach a light receiving section to the surface of the picture tube.

[Conventional technology]

Generally available commercially available picture tube surface contact type color luminance devices use adhesive such as tape when fixing the light receiving section to the picture tube surface, which may result in the adhesive remaining on the picture tube surface and the need to replace the tape. There were drawbacks such as the occurrence of setting time loss.

[Problem to be solved by the invention]

The above-mentioned conventional technology does not take into account the ease of setting the light receiving section onto the picture tube surface, requires the use of adhesive or the like to set the light receiving section, and also requires cleaning of the picture tube surface after the light receiving section is attached and removed. There was a lot of wasteful work that did not create added value, such as the need for

An object of the present invention is to improve the setting properties of these light receiving sections.

[Means to solve the problem]

The above object is achieved by providing a vacuum suction pad in the light receiving section and controlling a vacuum generator.

[Effect]

The vacuum suction pad vacuum-chucks the light-receiving portion by setting the light-receiving portion on the picture tube surface and turning on the vacuum generator. Furthermore, by turning off the vacuum generator, the light receiving section can be removed from the picture tube surface.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

The picture tube surface adsorption type colorimeter that is generally available on the market is the first.
As shown in the figure, it is composed of a measuring instrument main body 1 and a light receiving section 3.

The structure of the automatic suction type light-receiving section, as shown in FIG. 2, consists of a vacuum suction pad section 8, a switch 11 for controlling the attachment and detachment of the main body 7 of the light-receiving section, and the automatic suction control circuit is as shown in FIG. 3. A vacuum generator 13 for creating a vacuum inside the cage suction pad 3. Solenoid valve for electrically controlling compressed air 14. It consists of a power source 15.

The operation is as shown in Fig. 4, by positioning the light receiving section on the surface of the cathode ray tube and turning on the attachment/detachment control switch 11, compressed air flows into the vacuum generator 13, creating a vacuum inside the suction pad, and moving the light receiving section onto the surface of the cathode ray tube. is set to . When the light receiving section is to be removed, the compressed air is stopped by turning off the attachment/detachment control switch 11, and the light receiving section is removed from the cathode ray tube.

According to this embodiment, as shown in FIG. 5, there is no need to adhesively fix the light receiving section with tape as in the prior art, and the time for setting the light receiving section can be shortened. Additionally, cleaning the cathode ray tube surface after removing the light receiving section is no longer necessary.

〔Effect of the invention〕

According to the present invention, when adjusting the white balance of a color display, the light receiving part of the color luminance meter can be set on the cathode ray tube surface without using an adhesive such as tape, and by simply operating a switch. This has effects such as shortening the time for setting the light receiving part and eliminating cleaning work after attaching and detaching the light receiving part.
