Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a character input device, and more particularly to a character input device in which a desired character is input by a combination of partial forms that constitute a character.

A notation device such as the one described in the specification of Japanese Patent Application No. 14280/1983 (Description device for names, characters, symbols, etc. of the invention) is effective for notation of multi-character characters such as kanji. is proposed.

According to this notation device, the notation operation is performed using a partial form that is a part of a character, symbol, etc. (particularly a kanji) as one unit, and individual characters/symbols are created by combining one or more of these partial forms. etc. (especially kanji) are now written. The present invention is to simplify the configuration of a partial form input board in which selection means (keys, tablets, table look-up display frames, etc.) for each partial form are arranged in a character input device using partial forms as described above. In particular, the object is to reduce the number of selection means provided on the input panel compared to the total number of inputtable subforms.

According to this invention, the partial form input board is provided with selection means corresponding to partial forms that are parts of a character. Here, the selection means is a key, a tablet, a table look-up type display frame, etc., which has a display indicating the line drawing structure of the corresponding partial shape, and is pressed or touched with a pointing member such as a finger or a designated pen, or It means something that can be influenced by selection input actions such as proximity. A scribe can input a desired character by sequentially selecting and inputting one or more partial forms necessary to construct the desired character. The advantage of inputting partial forms in this way is that the same partial form can be shared between different characters, which reduces the number of selection means (the number of inputtable partial forms) provided on the input panel. This is much less than the total number of characters. This invention reduces the number of selection means arranged on the input board compared to the total number of inputtable part forms by associating two part forms with one selection means arranged on the part form input board. This is what I did.

This makes the partial form input panel much simpler than when each partial form and selection means are simply associated on a one-to-one basis. In this invention, one shift key is provided in association with the partial form input panel. Depending on the operation or non-operation of this shift key, one of the two partial forms corresponding to one selection means can be selectively input by the selection means. This invention does not make two partial forms correspond to all the selection means on the partial form input panel (
Doing so may make things even more complicated)
It shall apply only to those that are suitable to do so.
That is, the partial form input board is divided into a first area in which selecting means corresponding to only one partial form are arranged, and a second area in which selecting means corresponding to two partial forms are arranged. The shift key is effectively applied only to the partial form selection means belonging to this second area. It is preferable that the selection means arranged in the second area correspond to two partial shapes having the same abstract line drawing structure but different relative sizes. If the abstract line drawing structures are the same, only one partial form can be displayed on the selection means that corresponds to one of the partial forms. That is, even if two partial forms correspond to one selection means, if the abstract line drawing structure is the same, one display for retrieval can be used for both. Hereinafter, the present invention will be explained in detail based on the embodiments shown in the accompanying drawings. First, 1 in kanji
An example of how to provide partial shapes is shown below.

Figure 1 shows the relative positional relationship modules of various partial forms, where a is on the left side of the character, b is on the right side of the character,
c indicates the top of a letter or something that extends to the left or right from the top, and d indicates the bottom of a letter or something that extends to the left or right from the bottom. The area surrounding the letters is shown in C. 75) It shall belong to either d. In the figure, e indicates a letter located approximately in the center of the character, f indicates a letter located in the upper half, or to the left or right of the upper half, and g indicates a letter located in the lower half, or to the left or right of the lower half. What is shown in FIG. 1 is just an example, and the relative positional relationship module can be set in more detail or in a different format, but this will not be specifically mentioned here. FIG. 2 shows various sizes of the partial shape, and is an example in which the size of the partial shape (width in the lateral direction or vertical direction) is limited to several types.

The size in the horizontal (left and right) direction is, for example, 113 (Figure 2a), 2-3 (Figure 2b), 112 of the basic body shown by the broken line.
Classify into one of the ratios shown in (c). Further, the size in the height (up and down) direction is set to be a ratio of either 112 (d in FIG. 2) or 1 (e in the same figure) of the basic body shown by the broken line. In addition, the size of the partial form located at the top or bottom of the radical, such as the uppermost part or the lowermost part, should protrude somewhat above or below the basic body (Figure 2 f). . The size ratio is not limited to those mentioned above, and may be set as appropriate as long as it does not impair the beauty and balance of the finished characters. In addition, in the following, the width (simply 1 for the left and right)
13s1'2 or 213 means a dimension with a ratio of 113.112 or 213 to the width of the basic body, and the height (up and down) is simply 112.
, or 1 means a dimension that is a ratio of 112 or 1 to the height of the basic body. The specific types of subforms to be set and how to determine their sizes will be determined by considering the possibility of common use of these subforms between each character and the aesthetic appearance, but this point will not be discussed in detail here. However, I will only show one example. For example, the character 1 part yo has a partial form 0 ryo and a partial form RB. , can be divided into two subforms. The part of partial form 1 is on the left side (Fig. 1a), and its size is 113 (Fig. 2a) of the basic body. Further, the portion of the partial shape RBJ is on the right side (FIG. 1b), and its size is also 113. Therefore, partial form 1
The width of the character 1 part yo, in which Ryoyo and RBJ are combined in a predetermined positional relationship, is 3/2 of the basic body. Also,. The character rangyo can be divided into three partial forms Rr''J. (as shown in Figure 2 f)
Appears on the upper side of the basic body. The partial forms 1 YO and RBJ are the same as in the case of the 0 part YO. Therefore, the character 1-garu yo, which is created by combining three partial forms in a predetermined positional relationship, is somewhat larger than the character 1 part yo. Also, the partial form 1ryo and RB. J can be shared with many other characters other than this example. In addition, the partial form "r'yo" can be used in common with other kanji characters using the 1-madare yo. FIG. 3 is a block diagram showing an example of a character notation device to which the character input device according to the present invention is applied. 10, one or more partial forms constituting a desired character are sequentially selected and input, and a processing device 11 controls an output device 12 according to the selection on the input device 10, and outputs the selected partial form on the output device 12. The character is specifically written (printed, etc.), and as a result, the desired character is written by a combination of one or more selected partial forms.

The input device 10 includes a partial form input board 13 for selectively inputting various partial forms, and a code generation circuit 14 for generating information (code signal) representing the partial form selected by the partial form input board 13. In addition, one shift key 16
It is equipped with On the partial form input panel 13, selection means (keys, tablets, display frames, etc.) corresponding to all partial forms that can be input with this device are arranged, and on the top surface of each selection means there is a selection means corresponding to the selection means. The subforms are visible. Appropriate switches (contact type or non-contact type) are provided in connection with each selection means, and these switches are related to the code generation circuit 14. The input device 10, that is, the partial form input panel 13 and the code generation circuit 14, can be configured by a keyboard switch and a keyboard in which the relevant partial form is displayed on each key top. Or the pen touch method. It is also possible to adopt a configuration called.

FIG. 4 shows an example of the partial form input panel 13 when the table look-up method or pen touch method is adopted. Selection means 13a corresponding to various partial forms are arranged, for example, in the hand of a scribe. Motata instruction pen 15
When the selection means 13a of a desired partial shape is placed on the input panel 13, a switch (not shown) corresponding to that partial shape is closed. This switch is disposed below the input panel 13, and the switch used here is a so-called capacitive coupling type switch that forms a capacitance between the panel 13 and the indicator pen 15, or An appropriate method may be used, such as a so-called electromagnetic induction method in which a contact is built into the lower layer of the panel surface 13 and the contact is closed by the proximity of the indicator pen 15, or a pressure-sensitive method in which the contact is closed by the indicated pressure of the pen 15. configuration can be adopted. Further, each switch arrangement under the panel surface 13 may be a matrix-like connection arrangement. In addition, the shift key 16 is
3, and is designed to be operated by the hand opposite to the hand holding the pointing pen 15 (for example, the left hand).

The selection means 13a arranged on the partial form input panel 13 include:
Some correspond to only one partial form, while others correspond to two partial forms.

These two types of selection means 13a are arranged in a predetermined area on the input panel surface 13 in groups of the same type. The area in which selection means 13a corresponding to only one partial form are arranged is defined as a first area (1), and the area in which selection means 13a corresponding to two partial forms are arranged is defined as a second area (■).

FIG. 5 shows an example of the arrangement of the first area (1) and the second area (■) on the partial form input board surface 13. 1st
The region (1) and the second region (■) are further divided into finer regions, and in each finer region, partial form selection means 13a having common attributes are collectively (classified) arranged. This point will not be discussed in detail. Note that the attributes of a partial form that serve as criteria for classification into the above-mentioned narrow areas are the relative external dimensions (size) of the partial form and the relative positional relationship that the partial form occupies in the character. Now, each selection means 13a arranged in the second area (■) corresponds to two partial forms, but depending on whether the shift key 16 is operated or not, the selection means 13a corresponds to two partial forms. One of the partial forms can be selected and input by the selection means 13a.

For example, regardless of whether the selection means 13a selected by the input panel 13 is from the first area or the second area, the code generation circuit 14 outputs the selection means 13a to the input panel 13.
Generates a unique code signal. Therefore, the line 17 is selected based on the selection operation of the selection means 13a in the second area.
(FIG. 3) The code signal sent to the selection means 13
This is common to the two partial forms corresponding to a. on the other hand,
The signal on the output line 18 of the shift key 16 is applied to the processing device 11 together with the code signal on the line 17, and depending on whether the signal on the output line 18 of the shift key 16 is ``0'' or ``1'', it is in either partial form. It is determined whether there is.
Such determination is performed inside the processing device 11. That is, it is sufficient to program in advance which partial form should be selected when the shift key 16 is pressed. The selection means 13a arranged in the second area (■) are provided corresponding to two partial shapes that have the same abstract line drawing structure but different relative sizes.

An abstract line drawing structure is an abstracted outline of its partial form. Furthermore, the relative size refers to the relative size of a character in its vertical direction (vertical or vertical direction) or horizontal direction (horizontal direction). For example, there is a partial form located in the lower half of the character ``1 yo'' as shown in Figure 6a, and a partial form ``0 sun'' as shown in Figure 6b, which itself constitutes one character. , which constitute one character, are also included in the concept of partial form) have the same abstract line drawing structure but differ in relative size. 6th
Vertical dimension (ratio) of the lower half of the character in figure a
is 112, and the vertical dimension (ratio) of the character (partial form) in FIG. 6b is 212. In the second region, it is convenient if one of the two partial forms corresponding to each selection means 13a can itself constitute one character.

In other words, even with the partial form notation system, characters with a simple line drawing structure do not need to be composed of a combination of multiple partial forms, but one character can be composed of a single partial form. It may be more convenient. In such a case, the input panel 13 must be provided with a selection means 13a corresponding to a partial form that by itself constitutes one character. However, after introducing the idea of urgent partial forms and constructing a character input device, it became possible to
If the corresponding partial form were to occupy one selection means 13a, this would not be desirable. However, even such partial forms can be combined with other partial forms to form other characters, so in some ways they cannot be said to be a waste. In any case, if such a subform (a subform that can be a single character) and a subform with the same abstract line drawing structure but different relative sizes, these two subforms should be made to correspond to one selection method. This is convenient because it saves selection means. Next, FIGS. 7 and 8 show examples of partial forms that are classified into the second area (■), share one selection means 13a, and use the shift key 16 for different uses.

In FIGS. 7 and 8, an arrow S indicates that the shift key 16 has been pressed.

That is, in Figs. 7 a to c and Figs. 8 A and b, the arrow S
The partial form drawn on the left side is the partial form selected by the corresponding selection means 13a when the shift key 16 is not operated. The partial form drawn to the right of the arrow S is the partial form selected by the same selection means 13a when the shift key 16 is operated. It can be seen that the abstract line drawing structure is the same in each figure. Further, regarding the relative sizes, FIG. 7 shows a case where the sizes in the lateral direction are different. FIG. 7d shows the difference in relative size as a ratio (313 and 113).
FIG. 8 shows a case where the sizes in the vertical direction are different. FIG. 8c shows the difference in relative size as a ratio (212 and 112). From FIGS. 7a-c and 8A, b, each single selection means 13
It can be seen that the two partial forms shown correspond to a. Therefore, it is preferable that the display of the partial form on each selection means 13a be the display of the partial form that is selected when the shift key 16 is not operated. In the illustrated example, it is the partial form on the left side of the arrow S. Incidentally, the relationship between the partial forms selected by operating the shift key 16 may be reversed to that shown in FIGS. 7 and 8. That is, the partial form on the right side of the arrow S is displayed on each selection means, and when the shift key 16 is not operated, the partial form on the right side is selected, and when the shift key 16 is operated, the partial form on the left side of the arrow S is selected. It is also possible to do so. As explained above, according to the present invention, in a character input device using partial forms, the number of selection means on the partial form input panel can be made smaller than the total number of inputtable partial forms. The smaller size and fewer selection means make it easier to search for a desired partial shape.
