Abstract

PURPOSE:To automatically execute the decision of a picture quality by containing a comparator to compare arbitrary originals in a memory and a display device to display the result. CONSTITUTION:A comparator 8 to execute the comparison of the memory and a display device 9 to display the comparison result are provided, and the originals in the memory are compared. Consequently, encoded data to be read in a test original when a facsimile is normal are stored in the memory beforehand, and at the time of testing the facsimile, the test original is read, it is stored in the memory, both are compared with the comparator 8, the result is displayed on the display device 9, and thereby, the test of the facsimile can be executed without printing.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile machine having a memory for storing original documents.

[Conventional technology]

FIG. 2 is a block diagram of a conventional facsimile machine.

When transmitting this facsimile, a scanner 1 reads the document, an encoder 2 encodes it, and a memory 7 encodes it as necessary.
, and send it. When receiving data, the data received from the line 6 is stored in the memory 7 as necessary and sent to the decoder 4.
The data is decoded by the printer 3 and printed by the printing device 3. Here, the controller 5 controls the transmitter, receiver, and memory.

[Problem to be solved by the invention]

The above-described conventional facsimile has a drawback in that the image quality of the data encoded by the transmitter during transmission must be visually determined by actually printing the data.

Therefore, an object of the facsimile of the present invention is to be able to automatically judge image quality.

[Means to solve the problem]

The facsimile machine of the present invention has a function of comparing arbitrary documents in the memory, and a display device that displays the results.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a control block diagram of a facsimile embodiment of the present invention.

The facsimile of this embodiment is different from the conventional example shown in FIG. 2 by being equipped with a comparison device 8 for comparing memories and a display device 9 for displaying comparison results, so that documents stored in the memory can be compared. .

Therefore, the encoded data read from the test document when the facsimile is normal is stored in the memory in advance, and when the facsimile is tested, the test document is read and stored in the memory, and both are compared by the comparison device 8. By displaying the results on the display device 9, a facsimile test can be performed without printing.

〔Effect of the invention〕

As explained above, the present invention eliminates the need for printing and visual confirmation when testing the quality of a facsimile by comparing arbitrary originals in the memory, which saves time and effort, and automatically This has the effect of improving reliability because it makes decisions based on

[Brief explanation of drawings]

FIG. 1 is a control block diagram of a facsimile according to the present invention, and FIG.
The figure is a control block diagram of a conventional example.

Claims (1)

[Claims] In a facsimile machine that has a memory that stores scanned or received originals, a transmitting section that reads and sends the originals, a receiving section that receives and prints data, and a controller that controls them, it compares arbitrary documents in the memory. A facsimile machine comprising a comparison device and a display device for displaying the results.
