Under such an environment, conventional image data transfer apparatuses perform transfer processing by determining the destination number by operating a button or the like each time the image data is transferred to a different destination. Furthermore, when transferring a plurality of image data to different destinations, the image data is temporarily stored in a disk memory from the input device using a reservation function, a button, etc., and then transferred. Therefore, the time the user is restricted depends on the amount of data transferred, and as an improved version of this, the transfer device recognizes the characters of the destination number written at an arbitrary position in the image data read, and uses the recognition number as the basis for the transfer device. Transfer processing is performed that automatically dials the destination and automatically transfers image data, reducing fluctuations in the user's commitment time depending on the amount of data transferred.

(Problem to be Solved by the Invention) However, the conventional image data transfer method described above does not perform any processing on the result of character recognition of the destination number, and therefore, even if the recognized destination number is incorrectly recognized. However, the device will make a call to the telephone exchange, and as a result, the transferred data will be sent to a telephone line that the user did not intend, causing the major problem of leaking the contents of confidential documents to unrelated parties. have.

PIIIi means, recognition accuracy information means for detecting and outputting the degree of certainty of character recognition;
The above-mentioned image data transfer possibility determining means is provided for determining whether data transfer is possible based on a comparison between the degree of certainty of character recognition and the transfer level manually set by the user; When it is determined that transfer is not possible, this is achieved by the image data transfer device that displays the recognized destination number.

(Function) With the configuration of the present invention described above, the recognition accuracy output when character recognizing the destination number is compared with the transfer level set in advance by the user, and if the recognition accuracy is lower than the transfer level, the The recognition result is displayed on an LCD or the like without data transfer processing being performed. Therefore, by allowing the user to freely set the transfer level, which is the criterion for determining whether or not to transfer image data, the risk of confidential documents etc. leaking to the outside during transfer can be significantly reduced. By displaying recognition results that are below the transfer level on an LCD or the like, maintenance and the like can be easily and smoothly performed.
