Abstract

PURPOSE:To provide the image reading device which is good in usability by connecting a portable terminal device and the image reading device in one body and setting the height of the image reading device below the height of the portable terminal device. CONSTITUTION:The image reading device 3 consists of a platen for conveying a document, an image sensor which converts an image into an electric signal, a lens which converges the contents of the document on the image sensor, etc. In this case, the image reading device 3 is connected to a connector 19 fitted to the portable terminal device 1. Then the height H1 of the image reading device 3 is set below the height H2 of the portable terminal device 1 and the bottom surfaces when they are connected are in level with each other. Namely, while the bottom surfaces are in level with each other, the top surface of the image reading device 3 is in level with or lower than the surface of the tablet of the portable terminal device 1. Therefore, when pen input operation is performed, the image reading device 3 is never an obstacle.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image reading device connected to a portable terminal device using pen input.

[0002]

2. Description of the Related Art Conventionally, in order to connect an image reading device to a portable terminal device, it has been common to connect a connector to the portable terminal device using a cable as shown in FIG. Figure 6
1 is a mobile terminal device, 2 is a tablet, 3 is an image reading device, 4 is a document insertion port, 5 is a document ejection port,
6 is a cable for sending data of the image reading device 3 to the mobile terminal device 1, and 7 is a connector.

It is also conceivable to connect the portable terminal device 1 and the image reading device 3 via a connector 7 as shown in FIG.

[0004]

However, in the conventional portable terminal device, connecting the portable terminal device 1 and the image reading device 3 with a cable as shown in FIG. 6 requires holding the portable terminal device 1 in hand. There is a problem that the cable and the image reading device get in the way when used, and when the mobile terminal device 1 and the image reading device 3 are directly connected as shown in FIG. 7, the height of the image reading device 3 is higher than that of the mobile terminal device. Therefore, there is a problem in that the hand touches the image reading device 3 when the pen is input, which is unusable.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide an image reading device which is easy to use by integrally connecting the portable terminal device 1 and the image reading device 3. .

[0006]

To achieve this object, the height of the image reading apparatus of the present invention is set to be equal to or lower than the height of the portable terminal apparatus.

[0007]

With this configuration, an image reading device that is easy to use is provided.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a tablet 2 of the portable terminal device 1 in which a pen 8 is used to write figures, characters, numbers and the like to create documents and figures, and to recognize characters and numbers.

FIG. 2 is a circuit block diagram of the portable terminal device. In FIG. 2, reference numeral 9 is a CPU for controlling the mobile terminal device, 10 is a ROM containing a program for controlling the mobile terminal device, 11 is a RAM used by the CPU 9, and 12 is an input device for connecting the image reading device 3. The output port 13 is an image RAM for accumulating image data.

FIG. 3 is a sectional view of a mechanical portion of the image reading apparatus which is connected to the portable terminal apparatus to read an image and transmit the read image data to the portable terminal apparatus. In FIG. 3, 14 is a platen for conveying a document, 15 is an image sensor for converting an image into an electric signal, 16 is a lens for condensing the content of the document on the image sensor 15, and 17 is a casing of the image reading apparatus 3. is there. Original 1 as shown in FIG.
An image sensor 15 converts an original 18 into an electric signal from the insertion port 4 through the platen 14 and outputs the document to the ejection port 5.
Emitted from.

FIG. 4 is a block diagram showing a portable terminal device according to an embodiment of the present invention. The image reading device 3 is connected to the connector 19 attached to the mobile terminal device 1.

FIG. 5 is a block diagram showing a state in which the image reading device is connected to the side surface of the portable terminal device. The height H1 of the image reading device 3 is less than or equal to the height H2 of the mobile terminal device 1, and the bottom surface when connected is coplanar. That is, the bottom surface at the time of connection is flush, and the top surface of the image reading device 3 is the same as or lower than that of the tablet 2 of the mobile terminal device 1. Therefore, the image reading device 3 does not interfere with the pen input.

[0014]

As described above, according to the present invention, a user-friendly image reading apparatus can be realized when inputting with a pen.
