Abstract:
1. A medium processing device, comprising: a cylindrical drum that rotates about a central shaft; one or more inner tapes that are withdrawn from an inner reel on which the inner tapes are wound in advance and are wound onto a circumferential surface of the drum, at one or more locations in an axial direction along the central shaft of the drum; one or more outer tapes that are withdrawn from an outer reel on which the outer tapes are wound in advance and are wound onto the circumferential surface of the drum together with the inner tapes and a paper sheet shaped medium, with the medium interposed between the inner tapes and the outer tapes; a contrasting region that has contrasting physical properties to other regions, and that is formed at a terminal-end portion that is an end portion at the inner reel side or the outer reel side of at least one of the inner tapes or the outer tapes; a detection section that detects the physical properties at a tape position between the drum and the inner reel or between the drum and the outer reel, on a contrasting tape that is one of the inner tapes or the outer tapes formed with the contrasting region at the terminal-end portion; and a controller that controls rotation of the drum based on a detection result of the detection section, wherein a normal tape that is one of the inner tapes or the outer tapes not formed with the contrasting region at the terminal-end portion, has a length in a length direction that is longer than that of the contrasting tape by an additional length, the additional length being longer than a cutout length that is trimmed in a case in which an obstruction occurs in a portion of the normal tape.
