Abstract
In an image reading device, an object intrusion detecting device includes a rod-like member disposed along a widthwise direction of a document tray and detects that the rod-like member has been pushed up to a predetermined position in a height direction. When the object intrusion detecting device detects that the rod-like member has been pushed up to the predetermined abnormal position in the height direction, the controller determines that an object intrusion has occurred.
Claims6
An image reading device comprising:
- an image sensor that reads a document image from a document sheet;
- a document tray on which the document sheet is to be placed;
- a conveying device that conveys the document sheet toward the image sensor;
- a lifting device that lifts the document tray up and down;
- an object intrusion detecting device disposed above the document tray;
- and
- a controller including a processor;
- wherein the object intrusion detecting device comprises a rod-like member disposed along a widthwise direction of the document tray and detects that the rod-like member has been pushed up to a predetermined position in a height direction, and
- when the processor executes a control program and, thus, the object intrusion detecting device detects that the rod-like member has been pushed up to the predetermined position in the height direction, the controller determines that an object intrusion has occurred.
