Joining device and joining method (as amended)

A device that continually joins a plurality of joining members with a strip member, the device comprising:

• a first conveying assembly configured to convey in a longitudinal direction the strip member on which a plurality of placement members as indications of joining positions of the joining members are arrayed in the longitudinal direction;
• a second conveying assembly configured to convey the joining members to be joined with the strip member conveyed by the first conveying assembly;
• a joining roller configured to apply pressure to the strip member and each of the joining members and join the joining member with the strip member at a meeting point of the strip member and the joining member;
• a detector configured to detect passage of each of the placement members at a predetermined detection point on a conveyance path of the strip member;
• a conveyance controller configured to control the first conveying assembly and the second conveying assembly and determine a reach time when each of the joining members reaches the meeting point by the second conveying assembly, based on a detection time when passage of each of the placement members is detected by the detector;
• and
• a parameter acquirer configured to obtain a parameter related to an expanding or contracting state of the strip body, wherein
• the conveyance controller changes the detection time according to the parameter and determines the reach time based on the changed detection time.
