Abstract:
An entry detection device includes first light marks and second light marks. A control signal corresponding to a part of the first light marks is an error detection code of the control signal corresponding to the other part of the first light marks. A first inspection value is generated based on a first part of a light receiving signal corresponding to the other part of the first light marks. A second inspection value is generated based on a reverse bit string of a third part of the light receiving signal corresponding to a part of the second light mark paired with the other part of the first light marks. An entry is detected based on the first inspection value and the second inspection value.
