Abstract
A digital electronic apparatus includes a plurality of units and a cable. The plurality of units have metallic housings and are combined such that surfaces of the metallic housings are opposed to each other. The cable is laid on a surface of the metallic housing of at least one of the units. The surface on which the cable is laid is other than the surfaces of the metallic housings that are opposed to each other.
Claims1
A copying machine comprising:
- an image printing section having a first metallic housing having an inner surface and an outer surface;
- an image reading section having a second metallic housing, in which an upper housing of the first metallic housing and a lower housing of the second metallic house are opposed to each other;
- an image controller unit mounted on a rear side of the image printing section;
- a console unit mounted on a front side of the image printing section;
- and
- a cable connecting the image controller unit and the console unit, and extending along the inner surface of the upper housing of the first metallic housing by penetrating a rear housing of the first metallic housing and drawing out of the first metallic housing,
- wherein a portion of the cable is in contact with the inner surface of the upper housing of the first metallic housing, and the cable transmits a high-speed signal of at least 100 kHz.
