A positioning mark (20) has a shape by which a position and a direction c an be identified when moved together with a separator (10) along a plane. In other words, the positioning mark (20) is formed, for example, in a cross s hape so that a position on the X-axis and a position on the Y-axis and the t ilt in the ? direction of the positioning mark (20) can be identified. The p ositioning mark (20) is optically read by, for example, a sensor, and the po sitions on the x-axis and the Y-axis of the positioning mark (20) are calcul ated by, for example, image analysis processing. Based on the calculation re sult, positioning of the separator (10) is performed. |
