Tape supplying method and tape supplying device

A tape supplying device comprising:

• a mounting stand on which a first record wound tape and a second record wound tape are to be placed;
• a sending mechanism to send a tape;
• a guiding shaft that passes through hollow parts of the first record wound tape and the second record wound tape;
• a guiding ring arranged to surround a periphery of the guiding shaft;
• a sensor to detect the tape in an annular gap that has been formed between the guiding shaft and the guiding ring;
• and
• a rotation mechanism that rotates the first record wound tape and the second record wound tape,
• wherein:
• a tape end to an outer side of one record wound tape of the first record wound tape and the second record wound tape placed on the mounting stand and a tape end to an inner side of another record wound tape are connected, by matching a surface and a rear surface of the tapes;
• the sending mechanism supplies a tape of the first record wound tape and the second record wound tape from a tape end of the first record wound tape to an opposite side of a side that has been connected to the second record wound tape;
• and
• while the tape is drawn out in a direction perpendicular to an upper surface and a lower surface of the first record wound tape, the rotation mechanism is driven according to a detection result of the sensor, and the first record wound tape and the second record wound tape are rotated in a direction that solves a twist of the tape.
