Abstract

A flat cable winding device includes a case, a flat cable guide portion provided in the case and that introduces the flat cables into the case separately, a rotary table that is rotatable around a central shaft portion, a biasing unit that rotates and urges the rotary table in a winding direction of flat cables, a plurality of rollers that are rotatable around the central shaft portion on the rotary table, a separation guide path that guides the flat cables introduced into the case from the flat cable guide portion to the winding start position separately, and a slack absorption unit provided in the separation guide path and that absorbs slack of a flat cable located at an inner peripheral side.

First claim

What is claimed is:

1. A flat cable winding device in which a plurality of flat cables are wound in a stacked state whose one ends are connected to a central shaft portion of the flat cable winding device and other ends of the flat cables are feedable, the flat cable winding device comprising:
a case configured to accommodate the wound flat cables;
a flat cable guide portion provided in the case and configured to introduce the plurality of flat cables into the case separately;
a rotary table that is rotatable around the central shaft portion;
a biasing unit configured to rotate and urge the rotary table in a winding direction of flat cables;
a plurality of rollers that are rotatable around the central shaft portion on the rotary table and configured to wind one end sides of the plurality of flat cables in a stacked state by rotation of the rotary table in the winding direction;
a separation guide path that is provided between the flat cable guide portion and a winding start position of the plurality of rollers for the plurality of flat cables and configured to guide the flat cables introduced into the case from the flat cable guide portion to the winding start position in a state that the plurality of flat cables are separated to each other; and
a slack absorption unit provided in the separation guide path and configured to absorb slack of a flat cable located at an inner peripheral side among the flat cables when the flat cables are wound around the plurality of rollers.

2. The flat cable winding device according to claim 1 ,
wherein the separation guide path includes a plurality of guide members configured to guide the plurality of flat cables guided from the flat cable guide portion to the winding start position; and
wherein the slack absorption unit includes:
a movable guide member among the plurality of guide members that is movable in a direction intersecting a flat surface of the flat cable located at the inner peripheral side when the flat cables are stacked and wound around the plurality of rollers; and
an elastic member configured to apply a biasing force to the movable guide member and apply tension to the flat cable located at the inner peripheral side via the movable guide member.

3. The flat cable winding device according to claim 2 ,
wherein the plurality of guide members are constituted by guide rollers.

4. A flat cable routing structure comprising:
a plurality of flat cables whose first end portions are connected to a moving body which reciprocates with respect to a fixed body; and
the flat cable winding device according to claim 1 that is provided at second end portions of the plurality of flat cables opposite to the first end portions and configured to wind the plurality of flat cables pulled out by sliding of the movable body.
