Embodiment approach 9

[0500] The description of Embodiment Mode 9 has assumed a case where data communication is performed through one cable 905, but data communication can be performed through wireless communication. This wireless communication for this purpose includes microwave communication, optical communication, infrared communication or the like. When using this microwave communication, an antenna and a transmitter / receiver for transmitting and receiving microwaves are provided instead of the communication control section 901 shown in FIG. 24, and a similar antenna is also provided in the computer 903 And transmitter / receiver. With this structure, the computer 903 and the image data storage 701 are connected to each other through a microwave line.

[0501] When an optical communication is adopted, an optical transmitter / receiver having a light emitting part for emitting light and a light receiving part for receiving light is provided instead of the communication control section 901 shown in FIG. 2...

Embodiment approach 17

[0854] (First example of operation of embodiment 17)

[0855] An example of the operation of the image reader 2150 according to Embodiment 17 will be described below with reference to a flow chart of FIG. 86. Assume that the reading of an image is affected after a power switch that is not displayed is turned on, and it is assumed that the image reader 2150 (document detection section 105) shown in FIG. 85 is not close to a document. Then, in step SN1 shown in FIG. 86, the reading control section 2152 reports to the user that the image can be read by turning on a lamp or the like, and then the system control goes to step SN2.

[0856] In step SN2, the reading control section 2152 enables the input reception of a document detection signal S1 from the document detection section 105, and then the system control goes to step SN3. Here, the document detection signal S1 is a signal output from the document detection section 105 when a document touches (tightly touches) the image reading ...

Abstract

The image reader according to the present invention comprises a housing having substantially a box-shape and having an image reading surface contacting a document, a document detecting section provided to this image reading surface for detecting a document P, and an image reading section for reading an image on the document when the document P is detected by the document detecting section 105. This image reader enables improvement in convenience for users, operability, and adaptability for handling, and also it is small in size.

Description

[0001] This application is a divisional application for the invention patent application with the application number 99118095.X, the filing date on August 26, 1999, and the invention title "Image Reader". Technical field [0002] The present invention relates to an image reader, which can be conveniently used to read an image on a medium by manual operation. Background technique [0003] An image reader is a device used to optically read an image on a medium. Basically, image readers can be divided into three categories: a flat bed type, a paper feed type, and a handheld type. The flat bed type and the paper feed type image reader are independent devices on which a document can be placed and the document can be read. On the other hand, compared with the other two types of image readers mentioned above, the handheld image reader is a small device, so that this type of image reader can be easily connected to a desktop computer or a PDA (Personal Digital Assistant). In a handheld ima...
