Title:
OPTICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/092070
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an optical device for which the work of attaching a sheet-shaped coil having an integrated coil part to a moving part or a retaining part can be easily performed, and for which the attachment strength of the sheet-shaped coil to the moving part or the retaining part can be increased. An optical device (1) is provided with the following: a plurality of sheet-shaped coils (34) having integrated coil parts (33) facing drive-use magnets (38); and a flexible print substrate (35) that has coil attachment parts (35a) to which the plurality of sheet-shaped coils (34) are attached, and that is attached to the inner peripheral side of a case body (25). The thickness of the coil attachment parts (35a) is thinner than that of the sheet-shaped coils (34), and the width of the coil attachment parts (35a) in the vertical direction is narrower than that of the sheet-shaped coils (34) in the vertical direction. The coil attachment parts (35a) are attached to the inner peripheral side of the case body (25) in a state where the coil attachment parts (35a) are bent at the gap portion between the sheet-shaped coils (34) so as to follow the inner peripheral side of the case body (25) and are thereby formed into a roughly tubular shape.
