Abstract

PURPOSE:To increase the display capacity of the memory card using equipment by composing a system of a display element, a driving circuit, the memory card with the display which is provided with a display memory, and the memory card using equipment. CONSTITUTION:For a display on a display card, the dot pattern of a character to be displayed is read out of a KANJI (Chinese character) ROM 22 under the control of the CPU 19 of an electronic pocketbook 4 and written in the display memory 13 of the display card 1 through a memory card I/F 23. Then, an LCD driving circuit 14 makes a display corresponding to the dot pattern on an LCD 15. In this case, a program executed by a microcomputer mounted on the memory card using equipment is stored in a readable or writable memory 17 from the memory card I/F 23. In concrete, this program includes a program which writes display data in the display memory 13.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a memory card with a display and a device using the memory card.

[0002]

2. Description of the Related Art Conventionally, a device using a memory card such as an electronic notebook has been widely known.

[0003]

However, the conventional memory card-using device is excellent in portability, but has a drawback that the display capacity of the display is small and the information listing is insufficient depending on the intended use. .

An object of the present invention is to provide a memory card with a display and a memory card using device which can be used for various purposes by solving the drawback of lacking the information listing property of the conventional products.

[0005]

SUMMARY OF THE INVENTION The above-mentioned object is a memory card with a display that can be mounted in a device using a memory card in place of an ordinary memory card, the display element, a drive circuit for the display element, and a main body side. Memory card I
It is achieved by providing a display-equipped memory card having a display data storage memory writable from / F.

Another object of the present invention is to replace a display device, a drive circuit for the display device, and a display-equipped memory card having a display data storage memory writable from a memory card I / F on the main body side with a normal memory card. This is achieved by providing a device using a memory card characterized by being mountable.

[0007]

[Function] Some devices using the memory card have the surface of the memory card visible. In such a device, the display capacity can be increased by installing a memory card with a display instead of a normal memory card.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an external view of a display card (memory card with display) according to an embodiment of the present invention and an electronic notebook to which the display card is attached, and FIG. 2 is a circuit configuration diagram of each.

Although the electronic notebook 4 of FIG. 1 has a display 6, it has a display capacity of only four lines of Chinese characters, and the display capacity is insufficient for information retrieval and the like. In this case, when the display card 1 of the present invention is mounted, since the card has the display 2 having a display capacity of 7 lines, 11 lines can be displayed together with the display 6 of the electronic notebook 4, so that information can be displayed. The listability of is increased. 3 is a memory card connector on the display card 1 side, and 5 is an electronic notebook 4 provided so as to cover the upper surface of the display card 1.
The transparent touch panel on the side, 7 is also a memory card insertion slot.

Next, the display control content will be described with reference to FIG.

In order to display on the display card 1, the dot pattern of the character to be displayed is read from the Kanji ROM 22 under the control of the CPU 19 of the electronic notebook 4, and the display memory of the display card 1 via the memory card I / F 23 ( (Display data storage memory) 13. Then, the LCD 15 corresponding to the dot pattern
Is displayed by the LCD drive circuit 14.

The display control program executed by the CPU 19 at this time may, of course, be stored in the memory 20, but since this control program is executed only when the display card 1 is mounted, Then
It is stored in the memory 17 in the display card 1.
That is, the program executed by the microcomputer installed in the device using the memory card is stored in the memory 17 that can be read or written by the memory card I / F 23. Specifically, this program also includes a program for writing display data in the display memory 13.

When the display card 1 and the electronic notebook 4 are used to perform, for example, the input processing of the ordered product, the product category or the product name candidate to be input is displayed on the LCD 15 of the display card 1 and the desired product category is selected. By pressing the corresponding part of the transparent touch panel 5 on the product name or the product name, that is, the selection information is displayed for each pressing position of the transparent touch panel 5, and by simply pressing the transparent touch panel 5 in accordance with this, the selection information is easily displayed. Can perform input work. In addition to the above, the LCD 15 also displays information necessary for operating the card using device.

When the product classifications and product names are printed on the memory card as in the prior art, the number of product classifications and product names is limited to a few, which is impractical. The display information can be changed according to the situation in which the display is performed. A display example is shown in FIG.

On the side of the display card 1,
Reference numeral 16 is an address decoder, and 18 is a backup battery. Further, on the electronic notebook 4 side, 21 is an LCD drive circuit, 24 is an LCD, 25 is a battery, and 26 is a keyboard.

[0017]

As described above, according to the present invention, the display element, the drive circuit for the display element, the memory card with the display provided with the display memory, and the memory card using device to which the memory card can be attached are constructed. By installing the memory card, the display capacity of the device using the memory card can be expanded, and its application can be expanded.
