When the time has passed, the notification means 2
6, and a control means 25 for sending a signal to notify.

[0008]

Then, the original is set on the original reading surface 11, the original is pressed by the pressing plate 12, and the operation unit 13 provided on the pressing plate 12 operates the apparatus main body 10 to read the information on the original.

According to the third aspect of the present invention, after the switch means 24 detects that the pressing plate 12 is closed, the control means 25 starts timing after the reading of the original document, and the switch means 24 presses the presser foot. When it is detected that the plate 12 is opened, the time is cleared, and when a certain time has passed without being cleared, a signal is sent to the notification means 26 to notify that the original document after reading has been forgotten.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a document reading apparatus according to an embodiment of the present invention. Reference numeral 10 in the figure denotes the apparatus main body.
A document reading surface 11 is provided on the upper surface of the apparatus body 10. A pressing plate 12 covering the document reading surface 11 is attached to the inside of the document reading surface 11 so as to be openable and closable by a hinge 12a described later. The operation portion 13 is provided on the front upper surface of the holding plate 12.
To provide. As shown in FIG. 2, the operation unit 13 includes an operation plate 1
The display unit 15 and the input unit 16 are mounted on the connector 4, the connectors 17 are inserted into the respective connectors, and the harness 18 is connected to the power source of the apparatus main body 10. Harness 18
With the cover cover 19, the operation plate cover 20 covers the operation plate 14 except the display unit 15 and the input unit 16.

Then, the original is set on the original reading surface 11, the original is pressed by the pressing plate 12, and the main body 10 of the apparatus is operated by the input unit 16 of the operation unit 13 provided on the pressing plate 12 to place the original on the original. Read the information.

In the above-described embodiment, the case of the document reading device itself has been described. As shown in FIG. 3, the automatic paper feeding device 21 provided with the paper feeding tray 22 and the paper discharge tray 23 is used as a holding plate of the document reading device.
