GATE DEVICE, METHOD FOR CONTROLLING GATE DEVICE, AND PROGRAM

This gate device (10) is provided with a first light-emitting unit (110), a first person detecting unit (120), a second person detecting unit (122), and a control unit (140). The first person detecting unit (120) and the second person detecting unit (122) detect the presence of a person. The second person detecting unit (122) is positioned closer to the exit than the first person detecting unit (120). In addition, the control unit (140) changes the light-emitting state of the first light-emitting unit (110) from a first state to a second state that is different from the first state, using the detection of a person by the first detecting unit (120) as at least one condition. In addition, the control unit (140) sets the light-emitting state of the first light-emitting unit (110) to the first state using the time when the second person detecting unit (122) has detected a person as at least one condition. 一种闸机装置(10)，包括第一发光单元(110)、第一人员检测单元(120)、第二人员检测单元(122)和控制单元(140)。第一人员检测单元(120)和第二人员检测单元(122)中的每个检测到人员的存在。第二人员检测
