Abstract
An image reading device includes a feeding cable which connects a voltage applying part and a light source, and includes a conductive cable with an outer circumference covered with an insulating film. A first portion at one end side of the feeding cable is held by a first feeding cable holding member fixedly arranged in a vicinity of the voltage applying part. A second portion at the other end side of the feeding cable is held by a second feeding cable holding member attached to a first moving carriage that carries a light source and a first mirror. A portion of the feeding cable between the first and second feeding cable holding members is wound around a pulley in a U-shape. The pulley moves integrally with a second moving carriage that carries second and third mirrors.
Claims24
An image reading device, comprising:
- a first moving carriage configured to carry a light source that irradiates an image surface of an original document with light and a first mirror that reflects the light reflected from the image surface of the original document;
- a second moving carriage configured to carry at least one of a second mirror and a third mirror that reflects the light reflected from the first mirror;
- a voltage applying part configured to apply voltage to the light source;
- a feeding cable connecting the voltage applying part and the light source, the feeding cable including a conductive cable whose outer circumference is covered with an insulating film;
- a first feeding cable holding member fixedly arranged in a vicinity of the voltage applying part at a position along a moving direction of the first and second moving carriages to hold a first portion of the feeding cable at one end side of the feeding cable;
- a second feeding cable holding member attached to the first moving carriage to hold a second portion of the feeding cable at an other end side of the feeding cable;
- and
- a pulley configured to be rotatable in the moving direction of the first and second moving carriages and to move integrally with the second moving carriage, wherein a portion of the feeding cable between the first and second feeding cable holding members is wound around the pulley in a U-shape.
An image reading device, comprising:
- first means for moving and carrying a light source that irradiates an image surface of an original document with light and a first mirror that reflects the light reflected from the image surface of the original document;
- second means for moving and carrying at least one of a second mirror and a third mirror that reflects the light reflected from the first mirror;
- means for applying voltage to the light source;
- means for connecting the means for applying and the light source, the means for connecting including a conductive cable having an outer circumference covered with an insulating film;
- first means for holding a first portion of the means for connecting at one end side of the means for connecting, the first means for holding being fixedly arranged in a vicinity of the means for applying at a position along a moving direction of the first and second means for moving and carrying;
- second means for holding a second portion of the means for connecting at the other end side of the means for connecting, the second means for holding being attached to the first means for moving and carrying;
- and
- a pulley configured to be rotatable in the moving direction of the first and second means for moving and carrying and configured to move integrally with the second means for moving and carrying, wherein a portion of the means for connecting between the first and second means for holding is wound around the pulley in a U-shape.
