Abstract

PURPOSE:To obtain a highly accurate hand-written character input device without reducing a variety of functions in a limited area by forming a mode signal in accordance with the positional relationship between the placing stand of an input plane through which a picture image can be directly inputted and a supporting stand for supporting the placing stand. CONSTITUTION:A rectangular tablet 11 is provided as the input plane capable of directly inputting the picture image to the circular input plane placing stand 12. The placing stand 12 and the supporting stand 10 are linked to each other by a rotating spindle 20, and become rotatable. The rotating angle of the rotating spindle 20 is measured, whereby the relative positional relationship between the placing stand 12 and the supporting stand 10 can be detected. Said angle is measured by an angle detector 21 embedded on the supporting stand 10. The rotating angle detected by the angle detector 21 switches a mode specification.

Description

[Detailed description of the invention] [Technical field of invention] The present invention relates to an input device that allows direct input of images.

[Technical background of the invention and its problems]

Conventionally, input to word processors, electronic computers, and the like has been performed by using a large number of keys provided on a keyboard, and by depressing the desired key(s) by the operator.

However, in recent years, so-called handwritten character recognition devices have already been put into practical use that do not use these keys at all, but instead use tablets, liquid crystal panels, etc., to directly recognize and input handwritten characters. For example, using the schematic diagram of a handwritten character recognition device using a tablet in FIG. An area (menu area) (61) is provided on the board.The tablet area (60) used for handwriting is
When characters are written directly on the tablet, the image is recognized and input. For example, it is a tablet that performs functions such as half-width, double-width, and quadruple-width (hereinafter, the area is referred to as a menu area because it is a mode designation tablet that performs various functions). In other words, if a handwritten character recognition device that is easier for the operator to use is desired, the ratio of the menu area to the board is naturally increased.

However, as the menu area increases, the area of the handwritten character input tablet has to be reduced, which makes it difficult to determine whether the press is for the character you actually want to input or to specify the mode, which reduces accuracy. to ask for and
There is a problem in that seeking ease of use means writing in Japanese.

This is especially true for small handwritten character recognition devices that require only one character to be input using acupressure.

[Purpose of the invention]

The purpose of the present invention has been made in view of this situation,
The aim is to create a more accurate handwritten character input device in a limited area without removing various functions.

[Summary of the invention]

An input surface on which images can be input directly without key operations, an input surface installation base on which this input surface is installed, this input surface installation base as a support base, and a relative relationship between this support base and the input surface installation base. and means for creating a mode signal regarding the image input from the input surface from a signal C2 corresponding to the relative position C2 from the detector. I will provide a.

[Embodiments of the invention]

An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a plan view of an input device according to the present invention viewed from above;
FIG. 2 is a sectional view taken along the line α-β in FIG.

Outer periphery (circular input surface installation stand with two notches (12
) is equipped with a rectangular tablet αυ as an input surface on which images can be entered by hand. This tapelet) <11
) is a device that can recognize characters written by hand on a surface. A support stand α1 is formed so that the input surface installation stand @ on which the tablet αυ is installed can be embedded. This support stand α1 is fixed, and the circular input surface installation stand α1 is the input surface on which the support stand (1G (two pairs, rotatable, 1 m long) is installed. The installation stand α and the support stand α1 are connected through the rotation axis -C2, and the relative positional relationship between the input surface installation stand α and the support stand α1 can be determined by measuring the rotation angle of the rotation axis (to). This rotation angle is then measured by an angle detector embedded in the support base. The rotation angle detected by this angle detector Qυ is used to switch the mode designation.

For example, to specify the character size mode, when the rotation angle is @0'' (that is, the same state), ``full-width'',
When the rotation angle is 90°, r Double angle J1 When the rotation angle is 190° (90° in the negative direction), specify "half-width" and input character C
For each of the two, specify 1: perform the appropriate conversion. The angle detector ■υ is provided with a stopper that once stops rotating at a predetermined angle, and the origin position on the surface changes depending on the angle I. In the above example, in order to specify r times the angle j, first set the rotation angle to 90' (at this point, stop the rotation)
Even if the origin position changes from the position of the person in FIG. 1 to the position B, and rotation occurs, the input characters can be read correctly.

A processing system when the image processing apparatus of the present invention is actually used will be explained with reference to FIG. 3 and FIG. 4. First, the characters to be input are handwritten on the tablet (7) as shown in FIG. 4(a). Then, the signal of the coordinates (x, y) directly written on the tablet (2) is input to the coordinate conversion means C31). At this time, the angle detector (to) is the tablet (7)
Detects the rotation angle of and outputs angle information. This output signal is input to the coordinate conversion means (2I) and mode determination means, which will be explained later. In the coordinate conversion means Cυ, the signal of the coordinate (XIY) is converted into (X'F Y"
) l-disubstituted. In other words, "A" at rotation angle O0
When viewed from a certain reference plane, the former pattern is input as "on" and the latter as "to". Therefore, when the angle detector (to) outputs 90° angle information, the coordinate conversion means 3p converts the latter "-" coordinates (x, y) into coordinates (XI, Y/) that can be recognized as rAJ. be. This coordinate (x
'*y') signal is input to the recognition processing means C by two people, and for the first time, the rAJ pattern and the character rAJ are matched.

On the other hand, the angle information is inputted by the mode determining means C34), and the rotation angle C when characters are input is inputted and outputted from here according to the rotation angle C34). The above is the recognition processing means (
The character code output from (to) and this mode determination means (
For example, when the input character is in Fig. 4(a) and the rotation angle is 0°, mode information C output from
) When the full-width character ``jin'' has a rotation angle of 90 degrees, the half-width character ``jin'' has a rotation angle of 180 degrees as shown in Figure 4 (C).
In the case of °, the double-width character "mu" as a whole is output on the display as shown in FIG. 4(d).

[Other embodiments of the invention]

Note that the present invention is not limited to the above-mentioned Example C2.

The device used as the input surface is a tablet in the above embodiment, but any device such as a liquid crystal panel C may be used.

In addition, in the above embodiment, an angle detector was used that indicates the relative positional relationship between the input surface installation base on which the tablet is installed and the support base from the rotation angle, but for example, as shown in FIG. The installed input surface installation stand (51) is connected to the support stand (52)
There is also a method of detecting the positional relationship by making it possible to move vertically, horizontally, and C2 relative to each other. For example, a switch (50) is provided at each corner of the support base (52), and the mode designation is changed depending on which corner the input surface installation base (51) is in contact with. By doing this, the position of the input surface installation stand (51) can be seen at a glance, and the current specified mode can also be easily seen.

In the above embodiment, only the two editing instructions for the character size specification mode are used, but it can also be used for graphic input. For example, set the specified mode to ``1 circle''.
