Image Scanning Apparatus

摘要

An image scanning apparatus has a conveyer, a first scanning device configured to scan an image on one surface of an original sheet at a first scanning position, a second scanning device configured to scan an image on an other surface of the original sheet at a second scanning position. A controller is configured to execute a first adjustment process to adjust light amount adjustment of the first scanning device before scanning the original sheet subject to the received scanning instruction, start scanning after the first adjustment process, execute a determination process to determine, after starting conveying the original sheet, whether a light adjustment of the second scanning device is to be executed, execute a second adjustment process, when it is determined to start the light adjustment of the second scanning device, and stop conveying the original sheet when no original sheet is located at the first scanning position.

主权项

1. An image scanning apparatus, comprising:
a conveyer configured to convey an original sheet; a first scanning device configured to scan an image on one surface of the original sheet conveyed by the conveyer at a first scanning position; a second scanning device configured to scan an image on an other surface of the original sheet conveyed by the conveyer at a second scanning position; and a controller, the controller is configured to execute:
a first adjustment process to execute, in response to receipt of a scanning instruction, a light amount adjustment of the first scanning device before starting scanning of the original sheet subject to the received scanning instruction;a starting process to start conveying and scanning of the original sheet after executing the first adjustment process;a determination process to determine, after starting conveying the original sheet by executing the starting process, whether a light amount adjustment of the second scanning device is to be started;a second adjustment process to execute, when it is determined, in the determination process, to start the light adjustment of the second scanning device, the light adjustment of the second scanning device; anda stoppage process to stop conveying the original sheet such that the original sheet is not stopped at the first scanning position.
