Conveying device, image reading device, image forming apparatus, and conveying method

A conveying device comprising:

• a stacker to stack an object to be conveyed;
• a conveyor to convey the object in a conveyance direction;
• a feeder to feed the object on the stacker to the conveyor;
• an operation interface disposed in vicinity of the stacker to receive a switching operation to move the stacker;
• an actuator, in response to a receipt of the switching operation by the operation interface, to move the stacker between:
• a first position where the object on the stacker is at a feedable position by the feeder;
• and
• a second position where the object on the stacker is at a non-feedable position by the feeder, the non-feedable position below the first position;
• and
• circuitry configured to:
• perform the switching operation, in response to the receipt of the switching operation by the operation interface, to switch a mode of the actuator between:
• a first mode to move the stacker from the second position to the first position when the object is stacked on the stacker;
• and
• a second mode to move the stacker from the second position to the first position when the operation interface receives starting of conveying the object.
