Abstract

PURPOSE:To improve operability in the search and correction of an unread or misread character by using a display united handwritten input tablet to correct data inputted from an image OCR. CONSTITUTION:A tablet 4 displays the image data of an unread character on a liquid crystal display module 4b through a liquid crystal panel display control part 43 under the control of a display united type handwritten tablet control part 44. When an unread character/misread character exists, an operator draws a correct character on the tablet 4 by using a light pen 5. A recognizing part 42 in the tablet 4 recognizes the input character through a table input reading part 41 and sends the recognized result to the control part 44. The control part 44 displays the read image and the recognized result on the module 4b of the tablet 4 through the control part 43. Consequently, the operability in the search and correction of the unread/misread character can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a handwritten character input device, and particularly to a handwritten character input device suitable for use in correcting illegibility and misreading in an OCR device.

[Conventional technology]

For example, in processing transfer request forms in bank terminal systems, etc., the adoption of handwritten character OCR devices is being considered for the purpose of reducing the burden of keyboard operations on operators.

In conventional devices of this kind, handwritten characters and recognition results from an OCR device are displayed in parallel on a CRT display, and correction input for unreadable or misread portions is performed from the keyboard.

Related devices of this type include, for example, JP-A No. 6
No. 0-17572, No. 60-160484, No. 61-
Examples include devices disclosed in each publication of No. 163472.

[Problem to be solved by the invention]

In the conventional device described above, it is necessary to search for unreadable or misread characters on the display, select and press the corresponding character key on the keyboard, and the operability is poor and the operation takes time. For this reason, it is unreadable.

If there are many misread characters, there is a problem in that it is faster to input the characters directly from the keyboard while visually checking the handwritten characters on the slip.

The present invention has been made in view of the above circumstances, and its purpose is to solve the above-mentioned problems in conventional devices and to improve operability in searching and correcting unreadable and misread characters. The purpose is to provide an input device.

[Means to solve the problem]

The above object of the present invention is to provide image OCR and image OCR.
A handwritten character input device having a means for outputting data input from a CR and a control section for controlling these, wherein the control section includes a display output means for outputting data input from the image OCR, and an integral part of the display output means. A display-integrated handwriting input tablet consisting of a handwriting input tablet combined with a display-integrated handwriting input tablet is connected, and data input from the image OCR is corrected using the display-integrated handwriting input tablet. This is achieved by a handwritten character input device.

[Effect]

In the handwritten character input device according to the present invention, by using a display-integrated handwritten character input tablet, which will be described in detail later, an operator can write characters in the same manner as when viewing normal handwritten characters.

Displayed characters can be corrected and processing speed can be improved.

The above-mentioned display-integrated handwritten character input tablet is an improvement of the input device previously proposed by the present applicant in Japanese Patent Application No. 168326/1983 entitled "Image OCR Input Device", and is equipped with a transparent tablet and is placed directly below the transparent tablet. The system uses a display module consisting of a display module.

〔Example〕

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

FIG. 1 is a block diagram of a handwritten character input device showing an embodiment of the present invention. In the figure, 1 is a CRT display;
