Description

[Detailed Description of the Invention] The present invention relates to a small electronic device having a character display function.

In recent years, electronic translation machines that electronically translate words or sentences between languages of multiple countries, such as Japanese and English, have been put into practical use. This type of electronic translation machine is generally compact for portability, and therefore cannot display a large number of digits, which may result in long words or sentences being unable to be displayed. For this reason, in the past, a shift key was provided, and by operating this shift key, the displayed content was shifted toward the upper digits at a constant speed, making it possible to check the content even if the word or sentence was longer than the number of displayed digits. There is.

However, when the display content is shifted at a constant speed as in the above-mentioned conventional method, it is difficult to read the display content because it cannot match the reading speed of the user. One possible way to improve this shortcoming is to shift the displayed content one digit at a time by operating the shift key.
In this case, there is a problem in that the user does not know the end of a word or sentence and ends up using the shift key in vain.

The present invention has been developed in view of the above points, and when the display contents of the display section are shifted in accordance with the operation of a specific key, the end of the shift of character data to be displayed is detected and an acoustic signal is generated by sound or voice. It is an object of the present invention to provide a small electronic device that can prevent unnecessary key operations by notifying the user.

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a data memory that stores data to be displayed;
The data read from is input to the AND circuit 2. The gate of this AND circuit 2 is opened by an input command given from a control section (not shown), and its output is inputted to, for example, a 12-digit shift register 4 via an OR circuit 3. Furthermore, the output of this shift register 4 is input to, for example, an 8-digit shift register 5. The above shift register 4,
The contents of 5 are sequentially shifted by clock pulses from the control section, and the output of each digit of the shift register 5 is sent to the display section 6 at a predetermined timing and displayed. Further, the serial output from the shift register 5 is input to the OR circuit 9 via the AND circuit 7 and the one-digit shift register 8, and is also input to the OR circuit 9 via the AND circuit 10. A shift command is directly input to the AND circuit 10, and a shift command is input to the AND circuit 7.
1. The shift command is output from the control unit when a shift key provided on a keyboard (not shown) is operated. The output of the OR circuit 9 is input to the shift register 4 via the AND circuit 12 and the OR circuit 3 in series. Further, the input command is inputted to the AND circuit 12 via the inverter 13 . The output of the most significant digit of the shift register 4 is sent to the end code detection section 14. The end code detection section 14 detects a period code written at the end of a sentence or word, for example, and inputs the detection signal to an AND circuit 15.
Further, the above shift command is input to the AND circuit 15, and its output is sent to the buzzer drive circuit 16. A buzzer 17 is driven by this buzzer drive circuit 16.

Next, the operation of this embodiment configured as described above will be explained. When desired data is read from the data memory 1 by key operations on the keyboard, an input command is given to the AND circuit 2 from the control section, and the data read from the data memory 1 is sent to the AND circuit 2 and the OR circuit 3. is sent to shift register 4 via. The data read out to the shift register 4 is sent to the shift register 5, and is normally held in circulation via the AND circuit 7, shift register 8, OR circuit 9, AND circuit 12, and OR circuit 3.
For example, if the English sentence "THIS IS A PEN.", which is longer than the number of digits in shift register 5, is read from data memory 1, this English sentence is stored in shift registers 5 and 4 in rotation as shown in Figure 2A. . Then, at the timing when the first sentence T of the data read from the data memory 1 is shifted to the first digit of the shift register 5, "A" following the data "THIS IS" held in the shift register 5 at that time.
PEN.'' is not displayed because it is held in the shift register 4.

In the above display state, when the shift key is operated, a shift command is output from the control section, the gate of the AND circuit 10 is opened, and the gate of the AND circuit 7 is closed by the inverted output of the inverter 11. Therefore, the serial data output from the shift register 5 is taken out from the AND circuit 10, the OR circuit 9, the AND circuit 12, and the OR circuit 3.
The signal is input to the shift register 4 via. The above shift command is output while the data held in the shift registers 5 and 4 goes through one cycle, and then returns to "0". When a shift-low command is output in this way, the data held in the shift registers 5 and 4 goes around without passing through the shift register 8, so the data is shifted by one digit with respect to the readout timing to the display section 6. Timing becomes faster. Therefore, as shown in FIG. 2B, the contents of shift registers 5 and 4 are shifted to the left by one digit, and when the contents of shift register 5 become "HIS IS A", they are read out to display section 6 and displayed. . In this way, each time the shift key is operated, the displayed content is shifted one digit at a time in the direction of higher digits. Then, as shown in Figure 2C, Figure 2B
If you press the shift key four times from the display state, the display contents will change to "IS
PEN”. At this time, the period code is held in the most significant digit of the shift register 4. This period code is detected by the end code detection section 14, and the detection signal is input to the AND circuit 15. Therefore, the next shift key operation is performed as shown in FIG. 2D. When a shift command is output from the control section, the output of the AND circuit 15 becomes "1" and the buzzer drive circuit 16 operates, driving the buzzer 17 for a certain period of time to notify the end of the shift. Furthermore, the contents of the shift registers 5 and 4 are shifted to the left by one digit by the above shift command, and the last part of the sentence "SA PEN." is displayed on the display section 6.

In the above embodiment, the end of the display shift is detected by a period, but the invention is not limited to this.
It is also possible to detect when the blanking code has two digits at a time, or to detect other codes. Further, although the above embodiment has shown the case where a shift register is used, other registers inside a RAM (random access memory) may also be used. Further, in the above embodiment, the end of a sentence is notified by an alarm sound, but the present invention is not limited to this. The notification may be made by voice (for example, "the shift has ended"). Also,
The present invention is not limited to translation machines, but can be widely applied to other electronic devices that display characters.

As described above, according to the present invention, when the display contents of the display section are shifted in response to the operation of a specific key, it is possible to more reliably and easily recognize the end of the shift of the character data to be displayed, thereby eliminating unnecessary keys. It is possible to provide a compact electronic device that can be used efficiently by preventing manipulation.
