Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a small electronic information device in which information related to an input character is retrieved from a storage device and output and displayed by pressing or repeatedly pressing a search key after pressing a character key. This makes it possible to increase the learning function based on stored information without increasing the number of operation keys.

It has character keys such as kana keys or alphanumeric keys, and when these character keys are pressed, information related to the characters input is sequentially retrieved from the information in the storage device according to the press of the search key and output and displayed. Although small-sized electronic information devices having the function of, for example, an English-Japanese dictionary are already known, such conventional devices have merely had an information retrieval function similar to that of a normal dictionary.

SUMMARY OF THE INVENTION An object of the present invention is to provide a compact electronic information device that expands the conventional functions described above and adds an information learning function to an information search function without increasing the number of operation keys.

That is, the small electronic information device of the present invention is capable of learning by randomly extracting a large amount of information stored in a storage device by, for example, generating random numbers.

The present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an example of the configuration of a small electronic information device according to the present invention. In the illustrated configuration, K1 is a character code generation unit that generates alphanumeric keys such as A to Z and their respective character codes, and K2 is a processing key that includes a clear key and a processing code that generates each processing code. K3 is a search command generation section that generates a search key and a search command signal. Next, IB is an input storage unit that sequentially stores each character code generated by pressing the alphanumeric key K1 via the signal line L1, and F1 is an input storage unit that sequentially stores each character code generated by pressing the alphanumeric key K1. G1 is a flip-flop that outputs logic "1" to the Q terminal in the set state using the processing code from the processing key K2 via the signal line L2 as the set signal and the processing code from the processing key K2 via the signal line L2 as the reset signal.
It is a two-input AND circuit that receives the output and a search command signal input from the search key K3 via the signal line L3, and I1 is an inverter that generates an inverted signal for the Q output of the flip-flop F1, and G2 is the inverter. This is a two-input AND circuit that receives as input the inverted output signal of I1 and the search command signal via signal line L3. Note that a logic "1" is input from the signal line L3 for a certain period of time in response to the depression of the search key K3. Furthermore, RAN is a random number generation circuit that generates a random number according to the AND output logic "1" of the two-input AND circuit G2, and the CPU
has a function to constantly detect the memory contents of the input storage unit IB via the signal line L4, a function to start a search by determining the AND output of the two-input AND circuit G1, and an AND output of the AND circuit G. and the input storage unit IB according to the processing code via the signal line L2.
, a function to control the address counter AC that specifies the memory address of the fixed storage device ROM, and input codes and search result information by pressing the character key K1 to the output section OUT via the signal line L5. This is a central processing unit that has the function of supplying characters, converting them into character patterns, and then outputting and displaying the characters.

Furthermore, the random numbers generated from the random number generation circuit RAN are
A signal is applied to the address counter AC via the signal line L7 to randomly designate a memory address in the fixed storage device ROM, and to randomly extract information such as English words previously stored in the fixed storage device ROM. In addition, at this time, the memory address specified by the address counter AC is supplied to the address decoder unit ROMA of the fixed storage device ROM via the signal line L8,
The memory address of the information storage unit ROMB is accessed, the information at the specified memory address is read out, and is supplied to the output unit OUT via the signal line L9, and is converted into each character pattern and displayed as described above.

The small-sized electronic information device of the present invention configured as described above, for example, an electronic English-Japanese dictionary, operates as follows, for example.

First, by pressing the character key K1, the character code is temporarily stored in the input storage section IB, and at the same time, the flip-flop F1 is set, and the input character code temporarily stored in the input storage section IB is transferred to the signal line L4, The data is sequentially supplied to the output unit OUT via the central processing unit CPU and the signal line L5, and is displayed after being converted into a character pattern. After that, when you press the search key K3 after pressing several character keys K1, the search command signal is sent to the signal line L.
3 and AND circuit G1 in order to command the central processing unit CPU to start the search, the central processing unit CPU starts the address counter.
The count value of AC is incremented sequentially, and the memory address is sequentially changed by the increment of the AC count value, and the fixed memory is stored.
The memory contents of ROM1 are read out sequentially and input to the input storage section.
It is compared with the character code temporarily stored in IB, and when the required search is completed, information corresponding to the input character code is supplied to the output OUT as the search result via the signal line L5 and displayed.

Next, when processing key K2 is pressed, flip-flop F1 is reset and signal line L2 is reset.
The central processing unit CPU discriminates the processing code supplied via the signal line L5, and supplies a clear signal to the output section OUT via the signal line L5 to clear the previous display. Then, in this reset state, when the search key K3 is pressed, a logic "1" is output from the AND circuit G2, and the random number generation circuit
When a random number is generated in the RAM and the random number is applied to the address counter AC, the stored information at the memory address corresponding to the random number is read out, and randomly extracted information, such as an English word, is sent to the signal line L9. The information is supplied to the output section OUT and displayed to promote learning of English words.

As is clear from the above description, according to the present invention, in a small electronic information device such as an electronic English-Japanese dictionary, learning information is randomly extracted and displayed when a search key is pressed while no characters are being input. The learning function can be increased. Note that fixed storage devices that store information in advance include
For example, in addition to converting alphanumeric characters into binary codes and storing them, information on words made up of alphabets and translations related to those words are each converted into binary codes and stored with storage addresses attached to each. shall be kept. Therefore, during a search without character input, such information can be randomly extracted and displayed in various forms, such as only words, only translated words, or words and translated words together.
