Abstract

PURPOSE:To connect the portable terminal device and an image reader in one body and improve the usability by providing a power switch on a surface other than the surface where a read means and the portable terminal device are connected. CONSTITUTION:The portable terminal device has a CPU 10 which controls the portable terminal device, a ROM 11 where a program for controlling the portable terminal device is stored, and a RAM 12 that the CPU 10 uses. Further, this device has an input/output port 13 for connecting the image reader, an image RAM 14 for storing image data, a power source 15 for circuits, and the switch 8 of the power source 15. Then when the image reader is connected to the flank of the portable terminal device, the power switch 8 is fitted to the flank where the image reader 3 is not connected to the portable terminal device 1. Therefore, the portable terminal device which is conveniently used at the time of pen input operation is obtained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates 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 an interface cable as shown in FIG. In FIG. 6, 1 is a mobile terminal device, 2 is a tablet, 3 is an image reading device, 4 is a document insertion port, and 5 is a document insertion port.
Is a document discharge port, 6 is an interface cable for sending data of the image reading device 3 to the mobile terminal device 1,
Reference numeral 7 is a connector, and 8 is a power switch.

Image data is transferred from the document inserted through the insertion port 4 of the image reading device 3 to the interface cable 6
The original is displayed on the display screen 2 through the discharge port 5, and the document is discharged from the discharge port 5.

[0004]

However, in the above-mentioned conventional portable terminal device, connecting the portable terminal device and the image reading device with the interface cable as shown in FIG. 6 is used by holding the portable terminal device in hand. There is a problem that the interface cable and the image reading device get in the way when doing. When the mobile terminal device 1 and the image reading device 3 are directly connected, the power switch 8 is located on the connection surface between the mobile terminal device 1 and the image reading device 3, so that the mobile terminal device 1 and the image reading device 3 cannot be integrated. There was a problem that was.

An object of the present invention is to solve the above-mentioned conventional problems, and to provide a portable terminal device which is easy to use by integrally connecting the portable terminal device and the image reading device.

[0006]

In order to achieve this object, the portable terminal device of the present invention is provided with a power switch on the surface to which the image reading device is not connected.

[0007]

With this structure, the power can be turned ON / OFF even when the image reading apparatus is mounted.
