Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic book for the purpose of searching and displaying desired information (for example, daily life information, traffic information, etc.).

Traditionally, when going to an unfamiliar place, you need a map, a road map, etc., and when you want to cook an unfamiliar dish, you need a cookbook. We need a kind of textbook-like information material. Furthermore, as the information required becomes more detailed, the number of required materials increases, and the effort required to organize and understand them inevitably increases.

This invention enables the above-mentioned necessary information to be easily searched, and if it is miniaturized, a simple device similar to a conventional calculator can be provided.It has a built-in arithmetic processing unit and no external A main body provided with a keyboard for operating the arithmetic processing unit, and a cartridge detachably attached to the main body, with a display medium provided on the outside, and matters displayed through the display medium inside. and a built-in storage device for storing related information, and by operating the keyboard, the arithmetic processing unit can be operated and desired information can be displayed via the display medium of the cartridge. It is something. Therefore, by consolidating and storing the necessary information for each predetermined content in the storage device of one cartridge, it has become possible to easily and quickly obtain the necessary information simply by selecting a cartridge. be. Hereinafter, this invention will be explained with reference to examples.

FIG. 1 is a block diagram of the elements constituting the main body 1 and the cartridge 2. A display control device 8 is also connected to the arithmetic processing device 5, and a connection terminal 9 for a storage device and a connection terminal 10 for a display device are respectively drawn out from inside the arithmetic processing device 5. Cartridge 2 is ROM1
1 and a display device 12, and connection terminals 13 and 14 drawn out from each element can be connected to connection terminals 9 and 10 of the main body.

The apparatus shown in FIG. 3 embodies the above structure, and a cartridge 2 is detachably attached to the main body 1. The operation key section 7 is embodied as a keyboard 15 on the top surface of the main body 1. In the figure, 16 is input keys such as a numeric keypad and character keys, 17 is a command key such as a start key, erase key, and counter key, 18 is a function key, and 19 is a power switch. The cartridge 2 is provided with a display medium 20 on its upper surface, and the display device 12 varies depending on the mode of the display medium 20, and for example, a light emitting diode, a liquid crystal, etc. are used. In the illustrated example, the display medium 20 is made of paper, a synthetic resin board, a metal plate, etc., printed with a national railway network (it is even more effective if a private railway network is added).
A light emitting diode 21 serving as a display device is provided in the station area, and a liquid crystal 22 serving as a display device is provided on one side.
is provided. The function keys 18 on the keyboard 15 are given various definitions by a ROM 11 which is a storage device built into the cartridge 2, and definition contents 23 are displayed on the display medium 20.

FIG. 2 is a block diagram of the elements of another embodiment of the present invention, in which a so-called one-chip microcomputer is used as the arithmetic processing unit 5. In FIG. The one-chip microcontroller already includes a ROM 24, so data that can be shared among various applications is stored in this ROM 24.
The capacity of the ROM 11 provided in the cartridge 2 can be reduced, or it can be loaded with more abundant data. Furthermore, for the arithmetic processing unit 5 of the main body 1, a voice control device 25 and a voice generation device 2 are provided.
6, as well as a print control device 27 and an external output terminal 28, to improve the output function compared to the previous embodiment.

In the embodiments described above, various storage devices such as semiconductor memory, magnetic memory, hologram, etc. are used in the ROM 11 built into the cartridge 2.

Various applications can be considered for the electronic book of this invention. As shown in FIG. 3, on the display medium 20 provided on the surface of the cartridge 2, by operating the keyboard 15 to specify a place name, you can display the nearest station to get off at, or You can display the shortest course, required time, required cost, transfer station, etc. to go to the station.

FIG. 4 shows another embodiment of the cartridge 2, in which the display medium is a liquid crystal surface 29 provided at the center of the top surface. Therefore, the display device 12
directly forms the display medium. Such a cartridge can function as a cooking card, for example. That is, keyboard 1
By the operation 5, it is possible to display the names and amounts of ingredients required for the dish, and to display the cooking method.

FIG. 5 shows yet another embodiment of the cartridge 2, in which the display medium prints and displays a topographical map 30 and an expressway network 31, light emitting diodes 21 are provided at predetermined locations on the road network 31, and light emitting diodes 21 are provided on one side. A liquid crystal 22 is provided in the section. By inputting the name of a place, such a cartridge can display the nearest interchange, display the required time and cost, and display rest points according to the driving plan, or even display the route to the rest point. The remaining distance, remaining time, etc. can be displayed.

That is, according to the present invention, the cartridge is detachably attached to the main body, the main body has a built-in arithmetic processing unit, a keyboard for operating the processing unit is provided externally, and the cartridge has a display medium externally provided. Since a storage device is provided inside to store information related to the items displayed through the display medium, it is possible to obtain necessary information extremely easily by simply selecting a cartridge. .
