[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document image data reading apparatus for reading document image data of a document such as a document or a figure, and more particularly, to an automatic mode capable of automatically feeding a document, And a document image data reading apparatus having two modes of a handy mode for manually scanning the apparatus.

[0002]

2. Description of the Related Art In recent years, document image data reading apparatuses widely used in facsimile machines and the like include, in particular, an original moving type (auto mode) and an original stationary type (handy mode).
Japanese Patent Application Laid-Open No. 3-167958 discloses a portable document image data reading apparatus which makes it easy to switch the functions between the two.
The publication discloses the technique.

The outline will be described. The document image data reading device has a sensor block having a document reading sensor, and a roller block having a driving roller for moving a document, an auto mode in which the sensor block and the driving roller face each other, the sensor block and the sensor block. The sensor block and the sensor block are connected to each other by a rotatable connection member so that the roller block can take a handy mode in which the roller block is located on substantially the same plane.

When the above-described document image data reading apparatus is used in the handy mode, both the sensor block and the roller block are arranged so as to be opposed to the original surface when the roller block is opened. growing. Therefore, when used in the handy mode, it is difficult for the operator to grasp by hand and the operability is extremely poor. Furthermore,
When reading a document in the handy mode, there has been a problem that an extra space for reading the document is required by the area of the roller block in the plane direction.

Further, in the structure in which the sensor block and the roller block are connected by a hinge, since the two are separated from each other while rotating about the hinge, the electrical connection between the two is lacking in reliability.

The present applicant has filed an application for a document image data reading apparatus which solves the above-mentioned problem in Japanese Patent Application No. 8-280530. The outline will be described with reference to FIG.

FIG. 6 shows a document image data reading device 60.
FIG. 4 is a sectional view of a main part in a state of use in the automatic mode. The document image data reading device 60 mounts the sensor block 10 on the roller block 30 so that the reading surface of a reading sensor built in the sensor block 10 faces the roller block 30, and attaches the document to the sensor block 10.
The image data on the document surface is read by being automatically fed by a driving roller 31 built in the roller block 30.
