Abstract
With an automatic wicket apparatus, a commutation ticket is provided With a second record section for recording a character pattern corresponding to information for entrance or exit in the form of a magnetic latent image, besides a first record section for encoding and recording the information for entrance or exit. At the time of entrance, a character pattern including the date of entrance and entraining station name is recorded as a magnetic latent image in the second record section. At the time of exit, a character pattern including the date of exit and alighting station name is recorded as a magnetic latent image in the second record section. In case of suspicion, the character pattern in the form of a magnetic latent image in the second record section of the record medium is visualized by using a magnetic latent image-visible image conversion member.
