Abstract

PURPOSE:To avoid trouble of letting an opposite party retransmit by self- diagnosing a print section periodically, displaying it on a display section at the time of occurrence of a fault and storing reception data in a storage section. CONSTITUTION:A counter 3 counts the printed number of a print section 10 and outputs a signal when the count reaches a prescribed count number. Printed roll paper goes straight at a paper guide plate, read by a read section 11, fed by a read roller and discharged externally from the paper guide plate. Then a comparator section 12 compares data read by the read section 11 with original data in a text pattern storage section 2, and discriminates it normal when the degree of coincidence is, e.g. >=95%, and discriminates it abnormal when the degree of coincidence is less than that, and outputs a discrimination signal and displays it on a display section 5. When abnormal, a control section 7 does not print out received facsimile data but stores it to a storage section 9. Furthermore, when the check of print quality is finished, a changeover section 4 restores the page guide plate to the home position to restore the turning direction of the read roller.

Embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram showing an embodiment of a facsimile apparatus of the present invention, and FIG. 2 is a sectional view of an essential part of the facsimile apparatus of the present invention. In the figure, 13 is a telephone line, which is connected to the facsimile machine of the other party. Reference numeral 1 is a modem unit that demodulates the received data. A decompression unit 8 decompresses the demodulated data. A counter 3 counts the number of prints to be printed by the printing unit 10 and outputs a signal when the number of prints reaches a predetermined number. A switching unit 4 switches the transport direction of the paper guide plate and the rotation direction of the reading roller by the signal of the counter 3. A test pattern storage unit 2 stores a test pattern. A printing unit 10 prints the decompressed data of the decompression unit 8 on a sheet and the data of the test pattern storage unit 2 by the signal of the counter 3. A reading unit 11 reads the printed test pattern. Reference numeral 12 denotes a comparison unit, which compares the read data with the data in the test pattern storage unit 2 and outputs a signal indicating normal or abnormal. A display unit 5 displays the signal from the comparison unit 12. Reference numeral 6 denotes a detection unit which, when an abnormal signal is output from the comparison unit 12, determines that reception is impossible and disconnects communication. A storage unit 9 stores the data received thereafter without printing when an abnormal signal is output from the comparison unit 12. A control unit 7 includes the modem unit 1, the decompression unit 8, the counter 3, the switching unit 4, the test pattern storage unit 2,
The printing unit 10, the reading unit 11, the comparison unit 12, the detection unit 6, and the storage unit 9 are controlled.

In FIG. 2, reference numeral 15 is a facsimile machine which prints the received data on the roll paper 16 by the printing section 10. A roller 18 sends the roll paper 16. A paper guide plate 24 guides the roll paper 16 to the paper guide unit 21 or the paper guide unit 22 by switching the transfer direction of the guide plate.
A reading roller 19 serves to feed the roll paper 16 to the paper guide portion 22 and to feed an original inserted from the paper guide portion 22 to the paper guide portion 23. A receiving tray 25 receives paper. A cutter 26 cuts the roll paper 16. In the above configuration, the facsimile data transmitted from the line 13 is demodulated by the modem unit 1 and then expanded by the expansion unit 8. Then, the printing section 10 prints on a sheet. At this time, the paper guide plate 24 faces downward, the roll paper 16 is sent by the roller 18, printed by the printing unit 10, and discharged from the paper guide unit 21 to the outside. In order to check the printing quality (fault condition) of the printing unit 10 on a regular basis, the counter 3 sets the printing unit 1
The number of printed sheets of 0 is counted, and when a predetermined number of times is reached, a signal is output. The switching unit 4 receives a signal from the counter 3 and guides the paper guide plate 2.
4 is switched to the upper side 20 and the rotation direction of the reading roller 19 is switched (clockwise). After that, the roll paper 16 is sent by the roller 18 and the printing unit 10 prints the data in the test pattern storage unit 2. Printed roll paper 16
Goes straight to the paper guide plate 24, is read by the reading unit 11, is sent by the reading roller 19, and is discharged from the paper guiding unit 22 to the outside. The comparison unit 12 compares the data read by the reading unit 11 with the original data in the test pattern storage unit 2, and determines that the match is normal when the degree of coincidence is 95% or higher, and determines that the match is abnormal. Then, a determination signal is output and displayed on the display unit 5. In the case of an abnormality, the control unit 7 does not print the facsimile data received thereafter and prints it in the storage unit 9
Remember. Alternatively, the detection unit 6 transmits a signal to that effect to the facsimile machine of the other party and disconnects the communication. Switching unit 4
When the print quality check is completed, returns the paper guide plate 24 to the original position and returns the rotation direction of the reading roller 19 to the original position.
When the transmission original is read by the facsimile device 15, the original is inserted from the paper guide 22 and the reading roller 19 is inserted.
The document is fed by and the document is read by the reading unit 11.

[0008]

As described above, according to the present invention, the printing section is periodically self-diagnosed, and if there is an abnormality, it is displayed on the display section and the received data is stored in the storage section. It has an advantage that the received data is printed even if there is a defect in the printing unit, and it is not annoying to have the other party re-trust it because the interpretation is unclear.
