主权项

1. An automatic logout device installed in an electronic apparatus connecting with a user terminal device via a network, comprising:
an operation decision unit configured to decide whether a user operation exists or not on the electronic apparatus when a user instructing a job did not log out from the electronic apparatus after the job ended by the electronic apparatus; a memory configured to store a reference distance between the electronic apparatus and the user terminal device and an actual distance between the electronic apparatus and the user terminal device; a terminal device decision unit configured to decide whether the user operation exists or not on the user terminal device when it is decided that the user operation does not exist on the electronic apparatus; and an authentication unit configured to make the user log out from the electronic apparatus when it is decided that the user operation exists on the user terminal device; wherein the operation decision unit decides whether or not a job lapsed time after the end of the job is over a predetermined no-operation time when a user key operation except the logout does not exist, or whether or not an operation lapsed time after a preceding user key operation is over the no-operation time when the user key operation exists, and decides that the user operation does not exist when the job lapsed time or the operation lapsed time is over the no-operation time, and the no-operation time to be employed by the operation decision unit is longer than a time determined based on the reference distance when the actual distance is larger than the reference distance, and shorter than the time determined based on the reference distance when the actual distance is smaller than the reference distance.
