Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic device having a plurality of display sections.

Traditionally, people with language impairments asked others to do things,
Generally speaking, questions are communicated through written communication, but a conversation device has been proposed in which conversation is carried out by pressing a letter key and displaying a message corresponding to the pressed key.

FIG. 1 shows such a conversation device, in which 1 is a key for inputting the characters written on each key top, and the characters input from the key 1 are displayed on the display 2,
Conversation is carried out by showing this display to the other party. In addition, in translation devices that translate a first language into a second language, the first language input using a key is translated into the second language and displayed on the display. The display direction also faced the key operator, similar to the device shown in FIG. However, such devices have the disadvantage that when the key operator and the other party face each other, it is difficult for the other party to read the displayed characters.

The present invention provides an electronic device that eliminates such drawbacks of the prior art, and also provides an electronic device that is capable of displaying longer characters than one prior art device.

Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a perspective view of a conversation device to which the present invention is applied;
1 is a key similar to that shown in FIG. 1, and 3 is a display, which is composed of an upper display 3-1 and a lower display 3-2. Each of the displays 3-1, 3-2 consists of a liquid crystal display that displays characters in the form of dots. 4 is a switch that changes the display mode of display 3-1, 3-2,
By setting the switch heir 4 to the a position as shown in the figure, the same characters are displayed in opposite directions on the upper display 3-1 and the lower display 3-2.

That is, when MY NAME IS-... is entered sequentially from key 1, the characters on the lower display 3-2 are sequentially MY NA from right to left from the operator of key 1.
ME IS-... is shifted and output as a display from the force. On the other hand, on the upper display 3-1, the direction of the characters is 180° different from that on the lower display 3-2, and the characters are output in the order MY from left to right when facing the operator of key 1. NAME Is =-. is output.

Therefore, by reading the display on display 3-2 by the operator of key 1, and by reading the display on display 3-1 by the person facing the operator, both of them can read natural characters. It allows you to read the characters in an array.

Therefore, there is no need to perform operations such as changing the orientation of the device in order to have the other party read it.

Moreover, if the switch heir 4 is set to the b position, the upper stage display 3-1. The direction of the characters displayed on the lower display 3-2 is the same (in the example, the characters face the key operator side, but the characters on both displays are 180 degrees from the other party's side (operator side). It goes without saying that the upper stage display 3-1 and the lower stage display 3-2 can be arranged in series.

That is, from key 1, DID YOU HAVE A HA?
When you input RDDAY AT THE 0FFICE T, the lower display 3-2 first shows DID YOU)tA.
VE A HARD is displayed sequentially, and the lower display 3-
If the display capacity of 2 is exceeded, a new character will be input, resulting in an overflow. 4- Display the matched characters one after another on the right side of the upper display 3-1, shift the previously displayed characters to the left, and display DAY. A.T.
THE 0FFICE T is displayed sequentially.

FIG. 4 is a block diagram showing a control circuit of the conversation device shown in FIGS. 2 and 3. Reference numeral 11 denotes a decoder that converts a character signal input by key 1 into a character code signal corresponding to the character signal, and accesses character generators 12-1 and 12-2 based on this character code signal. As a result, a character pattern signal corresponding to the applied character code signal is output onto the signal lines SLI and SL2. The character generator 12-2 stores patterns of normal character shapes, while the character generator 12-1 stores patterns obtained by storing the normal character patterns by 180 degrees.

Therefore, when the character code signal of A (Alphapella) is applied to the full character generator 12-2, the pattern ""A" is sent to the signal @SL2
When it is applied to the character generator 12-1, it outputs "V#" to the signal line SLI.The drivers 13-1 to 13-2 display the applied character pattern signal. In addition to 3-1 and 3-2, there is a circuit for displaying, and when the shift terminal 14 is connected to ground, the display on display 3 changes from right to left (when displaying characters like i9i') is to shift what has been displayed until now to the left by one character and display a new character at the right end).

When the shift terminal 14 is open, the display is performed from left to right. 4-1.4-2 is a switch that is controlled by the switch heir 4 and operates in conjunction with it, and when the switch heir 4 is set to the a position, both switches 4-1 and 4-2 are connected to the a contact. , character generator 12
An output of -1 is applied to the driver 13-1, and the shift terminal 14-1 is opened.

Also, if switch 4 is set to b position, switches 4-1 and 4
-2 are both connected to b contacts, and drivers 13-1 and 13
-2 are connected in series, and the shift terminal 14-1 is connected to ground.

The operation of the electronic device configured as described above will be explained. First, with switch 4 in position a, press key 1.
When inputting MYNAME Is-... by operating , the character code signal from the decoder 11 is simultaneously applied to the character generators 12-1, 12-2.

Therefore, the character pattern signal generated from the character generator 12-1 is applied to the driver 13-1, but since the shift terminal of the driver 13-1 is in an open state, the second signal is displayed on the display 3-1. The input information is displayed as shown in the figure. Further, the character pattern signal generated from the character generator 12-2 is applied to the driver 13-2, but since the shift terminal 14-2 of the driver 13-2 is always connected to ground, the signal on the display 3-2 is There is a second
The input information is displayed as shown in the figure.

Next, with switch 4 in position b, DIDYOU...
..., as shown in FIG. 3, the character code signal from the decoder 11 is sent to the character generator 12-1.1.
2-2 is added at the same time. However, switch 4
Since -1 is connected to the b contact, the character generator 12-2
The output of is only applied to the driver 13-2.

In such a state, if information with a display capacity of 8- (for example, 20 digits) or less is input on the display 3-2,
The input information is displayed on the display 3-2, and nothing is displayed on the display 3-IK. However, if you enter a character with more than 20 digits, by entering a new character,
By shifting the characters already displayed to the left, you can
As a result of the overflowing characters being sent to the driver 13-1, these overflowing characters are displayed sequentially from the right end of the display 3-1.
The characters displayed on the screen will be shifted to the left by one digit.

Therefore, when the above-mentioned sentence example has been inputted, the display 3 will display as shown in FIG.

In addition, in this embodiment, an example was explained in which characters input using keys are displayed as they are, but in addition to this embodiment, the present invention also provides an electronic system that converts the input first language into a second language. Of course, it can also be applied to translators and electronic dictionaries that output synonyms of input information.

In this embodiment, an example in which two liquid crystal panels are used is used. However, if a liquid crystal panel capable of displaying two lines on one panel is used, the number of wiring lines will be reduced, and the effects of the present invention will be more effective. There is no need to mention it.

Further, in the embodiments of the present invention, a liquid crystal panel is used as a display device, but it goes without saying that similar effects can be obtained by using a display device such as a fluorescent display tube or a light emitting diode array EL.

As explained in detail above, according to the present invention, there is no need for an operator of an electronic device to change the orientation of the electronic device when showing display contents to the other party, and when a large amount of information is desired to be displayed, multiple display units are used. Since the display device can be used as one continuous display device, the display can be performed in a manner depending on the display content.
