Conveyance device and image forming apparatus |
摘要 |
A conveyance device includes a linear encoder that outputs an encoder signal corresponding to displacement of a conveyed object. The encoder includes an encoder fence provided on an intersecting plane that intersects a reference plane orthogonal to a direction in which a guide element supports the conveyed object. The encoder fence is configured such that a plurality of light-transmitting portions and light-shielding portions are arranged alternately on a side of the encoder fence. The light-transmitting portions and the light-shielding portions are formed so that a first point on each boundary between each of the light-transmitting portions and each of the light-shielding portions adjacent to each other and a second point on the each boundary, which is positioned separately from the first point with respect to a direction along the side of the encoder fence and perpendicular to the conveying direction, are separately positioned with respect to the conveying direction. |
