Abstract

A drawing apparatus includes a support for supporting a part of the grown form and a drive unit for causing a relative movement of the support and the grown form. The support includes a plurality of support units arranged in a width direction of the grown form orthogonal to a drawing direction of a plurality of extended forms, the plurality of support drawing the plurality of extended forms from the single grown form.

First claim

The invention claimed is:

1. A method for using a drawing apparatus for drawing a plurality of extended forms from a single grown form produced by growing carbon nanotubes, the drawing apparatus comprising: a single support member on which a plurality of support units are formed, the plurality of support units being configured to support parts of the grown form; a drive device supporting the single support member; and a drive unit configured to cause a relative movement of the drive device supporting the single support member and the grown form, wherein the plurality of support units are arranged in a width direction of the grown form orthogonal to a drawing direction of the extended form, and wherein the drive device is configured to move the single support member in a direction toward the grown form in order for the plurality of support units to support the parts of the grown form, the direction crossing the width direction and the drawing direction,
the method comprising:
supporting the parts of the grown form with the plurality of support units of the single support member supported by the drive device; and
causing the relative movement of the drive device supporting the single support member and the grown form to draw the plurality of extended forms from the single grown form.

2. The method according to claim 1 , further comprising an assist unit configured to assist the drawing of the plurality of extended forms so that the plurality of extended forms to be drawn out do not contact each other.

3. A method of drawing a plurality of extended forms from a single grown form produced by growing carbon nanotubes, the method comprising:
supporting parts of the grown form with a plurality of support units formed on a single support member supported by a drive device, the plurality of support units being arranged in a width direction of the grown form orthogonal to a drawing direction of the extended forms, the drive device being configured to move the single support member in a direction toward the grown form in order for the plurality of support units to support the parts of the grown form, the direction crossing the width direction and the drawing direction; and
moving one of the drive device supporting the single support member and the grown form away from another of the drive device supporting the single support member and the grown form, while supporting the parts of the grown form with the plurality of support units of the single support member supported by the drive device, to draw the plurality of extended forms from the single grown form.

4. A method of drawing a plurality of extended forms from a single grown form produced by growing carbon nanotubes, the method comprising:
supporting parts of the grown form with a plurality of support units arranged in a width direction of the grown form orthogonal to a drawing direction of the extended forms; and
(1) causing a relative movement of the plurality of support units and the grown form, and (2) causing a gap between directly adjacent ones of the plurality of support units to increase in the width direction, to draw the plurality of extended forms from the single grown form.
