The time required for the output to become “Lo” after placing
sensing object.
The time required for the output to become “Hi” after removing
sensing object.
Note: 1. These conditions are for the sensing of lusterless paper with an OD of 0.9 maximum located at the correct sensing position of the Sensor
as shown in the optical path arrangement on the next page.
2. These conditions are for the sensing of the paper supporting plate with an OD of 0.05 located using the glass plate without paper as
shown in the optical path arrangement on the next page.
