A transfer device for an electronic device, the transfer device being able to carry out calibration using a calibration plate having first and second alignment marks arranged in one direction and third and fourth alignment marks arranged in another direction orthogonal to the one direction, and transferring a transfer article that constitutes the electronic device to an object, comprising:
- a table having a support surface that can selectively support the calibration plate and the object;
- a table supporter that supports the table such that the table is movable in first and second directions that are parallel to the support surface and orthogonal to each other, and supports the table such that the table is rotatable about an axis orthogonal to the support surface;
- a movement driver that moves the table supporter in the first direction among first, second, third and fourth positions;
- a transfer roller that has a rotation shaft, and an outer peripheral surface that can hold the transfer article and includes a reference line parallel to the rotation shaft;
- a shaft supporter that supports the transfer roller such that the transfer roller is rotatable about the rotation shaft;
- a rotation driver that rotates the transfer roller;
- a first imager that has a field-of-view including a first reference index, images the first alignment mark when the table supporter is in the first position with the calibration plate supported by the table, images the second alignment mark when the table supporter is in the second position with the calibration plate supported by the table, and images the third alignment mark when the table supporting the calibration plate is in the third position;
- a second imager that has a field-of-view including a second reference index and images the fourth alignment mark when the table supporter is in the third position with the calibration plate supported by the table;
- a third imager that has a field-of-view moving together with the table supporter and including a third reference index, images the third alignment mark of the calibration plate when the table supporter is in the third position with the calibration plate supported by the table, and images the reference line of the transfer roller when the table supporter is in the fourth position;
- and
- a fourth imager that has a field-of-view moving together with the table supporter and including a fourth reference index, images the fourth alignment mark of the calibration plate when the table supporter is in the third position with the calibration plate supported by the table, and images the reference line of the transfer roller when the table supporter is in the fourth position;
- and
- a display that displays images imaged by the first, second, third and fourth imagers, wherein
- the first and second imagers are provided such that positions of the first and second imagers are adjustable independently from the table supporter, the third and fourth imagers are provided such that positions of the third and fourth imagers are adjustable relative to the table, and the transfer roller is provided such that an orientation of the transfer shaft is adjustable at least in a plane parallel to the support surface.
