Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card type display device, and more particularly to a card type display device used for an electronic enlarging device, an electronic translation device or an electronic dictionary.

[0002]

2. Description of the Related Art Conventionally, a device for reading an image by a one-dimensional line sensor and outputting and displaying the image by a printer or a display is well known.

[0003]

However, when the one-dimensional line sensor is used, an operation of moving the one-dimensional line sensor relative to the two-dimensional image and scanning is required, and the reading time is increased. In addition to being long, the reading device and the output device are separate, so miniaturization is extremely difficult.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and is a card type in which a reading unit and a display unit are integrated into a card shape, and is read immediately and displayed. An object is to provide a display device.

[0005]

In order to achieve this object, a card type display device of the present invention is a complete contact type two-dimensional image sensor which is placed in close contact with an original and reads the original image in the reading area. And a double-sided emission type light source that is laminated on this two-dimensional image sensor and emits illumination light downward to illuminate the document surface through the two-dimensional image sensor and also emits illumination light upward. The liquid crystal display is characterized in that the liquid crystal display is laminated on the light source and displays an image by using illumination light emitted upward.

[0006]

According to the above construction, the image of the original can be read by the two-dimensional image sensor which is in close contact with the original and the image can be immediately displayed on the liquid crystal display. In this case, the dual emission type light source sandwiched between the two-dimensional image sensor and the liquid crystal display illuminates the document surface on the one hand and serves as the light source for the liquid crystal display on the other hand.

The present invention relates to an electronic enlargement device, an electronic translation device,
It can be applied to an electronic dictionary, a business card file device, an electronic handwritten character recognition device, or the like.

Further, as the LCD 5, an LCD having a peripheral drive circuit using TFTs and having a high precision and full color is used.

FIG. 2 shows the system block of this embodiment. Original information such as characters and images read by the two-dimensional image sensor 3 is subjected to A / D conversion, encoding processing, etc. in the input processing unit 11. After being processed by the data processing unit 12, the data is displayed on the LCD 5 as output information via the output processing unit 13. The input processing unit 11, the data processing unit 12, and the output processing unit 13 are built in the control unit 8 including a CPU, and the built-in memory and memory card 14, the touch panel 6 and the keyboard 9 are connected to this. Further, the output data can be transferred to another printer or the external file 16 after being processed by the transfer processing unit 15.

The present embodiment thus constructed can be applied to various devices as described below. (1) Electronic magnifying device The card-type display device 1 is placed on the original 2 in close contact, the original surface is illuminated by the dual emission light source 4, and the original image is read by the two-dimensional image sensor 3.

[0018]

As described above, according to the present invention, it is possible to provide a small information tool that complements the weaknesses of an individual who copes with an internationalized and aging society. Since each function can be processed and calculated based on the information stored in each memory or memory card, the use range of the function is extremely wide. Since the original image is read by the two-dimensional image sensor, the information input time is very short. Since a dual emission light source is used, it is possible to make it thinner.
Convenient to carry as a card. Since the image input information is immediately displayed on the LCD screen, the input target can be confirmed in an instant. All or part of the processing function can be instructed while viewing the image on the LCD screen. Moreover, since the processed image can be displayed together with the original image, the confirmation and correction of the processing function can be performed immediately. Since it is possible to connect to external information equipment by system transfer, it is easy to expand the functions. And so on.
