Abstract

A mechanism for fixing a transmission cable enables a wiring shape of a flat cable to be held relatively reliably when the cable is acted upon by torsion force, tensile force and the like from the outside without the cable skin sustaining damage. A foldable insulation sheet is joined in folding surfaces, and a position of the flat cable is regulated by at least the fold portion thereof and joint portion. The mechanism is includes a flat cable, a foldable insulation sheet, and joint portions for joining folding surfaces of the insulation sheet. At least one of the fold portion of the insulation sheet and the joint portions is disposed in a position for regulating the flat cable. Thus, the flat cable is nipped by the folding surfaces of the insulation sheet, and its wiring shape is held by the fold portion or the joint portion.

Claims

1. A mechanism for fixing a cable for transmitting a signal or power, comprising:

a flat cable;

an insulation sheet foldable in a predetermined fold portion; and

a joint section adapted to join folding surfaces of the insulation sheet to form a predetermined joint portion,

wherein at least one of the fold portion of the insulation sheet which sandwiches the flat cable and the joint portion is disposed in a position for regulating the flat cable.

2. The mechanism for fixing a transmission cable according to claim 1, wherein the joint section is a joint layer structure including an adhesive layer, a welding layer and a crimp layer formed on the folding surfaces, a joint tool structure including a tie tool and a binding needle attached to the folding surfaces, or a fit structure including a protrusion portion and a concave fit portion, and a slit and a insertion piece formed in the folding surfaces to engage in each other.

3. The mechanism for fixing a transmission cable according to claim 2, wherein a retaining fix portion to fix to a structure is formed in the insulation sheet, and the retaining fix portion is a retaining hole that engages in a protrusion of the structure, or a lock hook that engages in a concave portion of the structure.

4. The mechanism for fixing a transmission cable according to claim 3, wherein the insulation sheet is made of a synthetic resin film material, and

the slit of the joint section and the retaining hole of the retaining fix portion are formed by die cutting in the film material.

5. The mechanism for fixing a transmission cable according to claim 1, wherein in the insulation sheet, the joint portion is disposed while being spaced a predetermined distance apart from the fold portion, and a position of the flat cable is regulated between the fold portion and the joint portion.

6. The mechanism for fixing a transmission cable according to claim 5, wherein the flat cable is bent and deformed in a crossing direction, and in the insulation sheet are formed a first joint portion formed while being spaced a predetermined distance apart from the fold portion, and a second joint portion disposed in a direction for crossing the fold portion, and

the fold portion and the first and second joint portions are disposed at distances for regulating a position of a bent deformation portion of the flat cable.

7. An image reading apparatus comprising:

a scanning section adapted to be able to shift along a read image;

a control section adapted to control the scanning section; and

a transmission cable adapted to electrically connect between the scanning section and the control section,

wherein the transmission cable includes the mechanism for fixing a transmission cable according to claim 1.
