Abstract
A document handler is provided with a casement 1 which comprises a lower case 6 which has a lower cover 7 for providing a bottom surface of a passageway 5 and a lower tray 8 attached to a bottom of lower cover 7 to form therebetween a lower cavity 3d in which lower optical sensing element 3a of optical sensor 3 is disposed. Even if liquid spilled on a main surface of the table may often enter passageway 5 to the rear from the bill inlet, there is incurred no damage to electric instruments in lower cavity 3d by extraneous substance which is discharged through a drainage 15.
Claims23
A document handler comprising:
- a casement for defining a passageway,
- a conveyer for transporting a document along the passageway,
- an optical sensor having at least one lower optical sensing element for detecting physical features of the document moving along the passageway to produce detection signals, and
- a controller for receiving the detection signals from the optical sensor to control operation of the conveyer,
- wherein the casement comprises a lower case which has a lower cover and a lower tray attached to a bottom of the lower cover to form a lower cavity between the lower cover and lower tray,
- said lower cover being formed of a light-permeable and water-shedding plastic material for providing a bottom surface of the passageway,
- the lower optical sensing element of the optical sensor is disposed within the lower cavity.
