Embodiment Construction

[0025] Electronic devices according to embodiments of the present invention are described below.

[0026] figure 1 is a schematic diagram showing the structure of the electronic device according to the first embodiment of the present invention.

[0027] The electronic device according to this embodiment of the present invention is a television receiver 10 using a cathode ray tube 11 . The television receiver 10 has a front cabinet 12 surrounding a peripheral portion of a panel 11A of a cathode ray tube 11 . The front cabinet 12 is made of metal.

[0028] That is, by utilizing the metal front cabinet 12, the benefit of the television receiver 10 of this embodiment is that it is superior in structural design to a television receiver that utilizes synthetic resin to form the front cabinet, and achieves a higher performance than that in the case of utilizing synthetic resin. Product specifications with higher image quality below.

[0029] The television receiver 10 is provided...

Abstract

An electronic device having a housing at least partially composed of metal, comprising: a discharge circuit connecting a metal part of the housing to a ground provided in the electronic device, the discharge circuit comprising a parallel circuit consisting of a resistor and a discharge tube .

Description

[0001] This application is a divisional application of an invention patent application with an application date of November 22, 2000, an application number of 00128528.9, and an invention title of "Electronic Device". technical field [0002] The present invention relates to an electronic device having a casing including metal parts. Background technique [0003] Conventionally, for example, in many television receivers utilizing cathode ray tubes, a cabinet surrounding a peripheral portion of a panel of the cathode ray tube is formed of synthetic resin. [0004] However, there are cases where it is necessary to utilize a metal cabinet in order to provide a camera with high-quality images or to improve design performance. In such cases, the metal chassis needs to be grounded. [0005] To this end, various methods are employed in which a metal element such as the above-mentioned metal chassis and a ground portion provided on the bottom plate of the electronic device are dire...
