Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a facsimile device that reads image information from a medium, and more particularly to an improvement of a facsimile device equipped with a code identification function, a so-called OMR function.

Normally, in a system where multiple facsimile devices are connected to a broadcast device, etc., the calling side facsimile device can specify multiple called side facsimile devices, so that the broadcast device can specify the called side's telephone number, device number, etc. Information that can identify the address is sent from the facsimile machine before sending the image information.

In addition, such address information can be read by an optical mark reader (
There is a known method of reading data written on a manuscript such as an OMR (hereinafter referred to as OMR) from a device that can read and identify the data and notifying these broadcasting devices. It has also been proposed that a facsimile device is provided with an optical mark reading function that also serves as a mark reading section, and is configured to notify the above-mentioned address information and the like.

However, in these conventionally proposed facsimile machines, the sheet used in the OMR device (hereinafter referred to as OMR
In order to distinguish between facsimile originals and facsimile originals, an identification mechanism must be provided in the middle of the medium path, which has the disadvantage of unnecessarily lengthening the medium path and increasing the size. There is.

SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile machine which eliminates the above-mentioned conventional drawbacks and can shorten the path length.

In the present invention to achieve the above object, original or OMR
The reading signal from the means for reading data on the sheet is identified to identify whether it is a facsimile original or an OMR sheet, and a cut is made on the OMR sheet to indicate the point at which this reading signal becomes effective. This is the point in time when a sensor on the passage corresponding to the notch detects the cutout.

This makes the device more compact, and in the case of facsimile originals, this scanning for identification does not involve scanning the original, so all the reading signals from the leading edge to the trailing edge of the original are converted into image signals. It has an effect that can be converted as The present invention will be described in detail below based on examples.

FIGS. 1A and 1B are explanatory diagrams of an OMR sheet and a facsimile original according to an embodiment of the present invention. FIG. 2 is a block diagram of a reading device according to an embodiment of the present invention.

In Fig. 2, 1 to 6 are paper feed rollers, V is a tray, 7 is a pulse motor, 7/ is a belt, 8 is a reading light source, 9 is a document detection sensor, 10 is an optical system, 11 is a reading sensor, 12 is an amplifier; 13 is a binarization circuit that binarizes the read signal; 14
1 is a timing control circuit, and 15 is a document detection circuit.

Also 0S1. is an 0MR sheet, and 0S2 is a facsimile original. The OMR sheet 0S1 is fed in the direction of the arrow shown in FIG. 1a by paper feed rollers 1 to 6 shown in FIG.
1 is provided with a notch portion 0S10 at the tip portion 0S12 in the feeding direction.

Further, a mark 0S11 made of a black bar of a predetermined width is provided around the tip 0S12. Furthermore, the aforementioned address information is provided with a mark 0S14 shown by a wavy line between marks 0S13 and 0S13 (usually this mark is written in a so-called drop-out color that cannot be read by optical detection means), and is located at a predetermined position. Mark 0S1
By writing line 0S16 in 4, the operator specifies the destination 0S15, in this case the ``Kawasaki'' station. Further, since the facsimile original 0S2 is not provided with a notch at the leading edge 0S12, normal paper can be used.

The operation of the block diagram in FIG. 2 will be explained based on FIGS. 1A and 1B.

When sending a facsimile, the operator first sends the 0MR sheet 0S1 filled in with the 4 recipients and the original 0S2 to the receiving tray 1.
V, and press a send button (not shown).

As a result, the paper feed rollers 1 and 2 are driven in the direction of the arrow.
For example, the OMR sheet 0S1 is first taken into the apparatus.

At this time, the paper feed pulse motor 7 is driven, and the document is moved downward at a predetermined pitch between rollers 4, 5 and presser rollers 3, 6, which are rotated by a belt 7'. A sensor 9 such as a micro switch or a photo sensor is provided in this passage at a position corresponding to the cutout portion OS10. Further, light is constantly irradiated from the light source 8 to the document position, and the reflected light is reflected by an optical system 10 such as a lens.
A reading sensor 11 composed of a charge-coupled device etc.
The light is received by sensor 9 and this reading sensor 1
The relationship between 1 and the reading position is as shown in Figure 1A and b.
At the time when the photo sensor 9 detects the tip end 0S12, the reading sensor 11 is arranged so as to read the position shown by the dashed line in the figure. As a result, in the case of 0MR sheet 0S1,
The mark 0S11 is now included in the read signal output by the read sensor 11. Furthermore, at the time when the sensor 9 outputs the detection output via the detection circuit 15 (FIG. 2), the facsimile original has not reached the reading position of the leading edge of the original 0S12 reading sensor 11, and the reading sensor is not connected to the back panel. The reflected light is read and output. For this purpose, for example, it is possible to write white or a predetermined coded pattern on the back panel and read it. The signal read by the reading sensor 11 is a signal generated by the timing control circuit 14, and is supplied to the amplifier 12, amplified, and converted into a binary level signal by the binarization circuit 13, which is output.

In FIG. 2, the signal detected by the detection circuit 15 is supplied to the control section 18.

The control unit 18 uses this detection signal to control the timing control circuit 1.
The clock CLK supplied from 4 and the read signal VID read by the read sensor 11 and binarized are made valid by the pulse width detection circuit 16. That is, the pulse width detection circuit 16 is provided with an AND gate for each signal, and becomes valid when the AND gate is opened by a signal from the control section 18. As a result, for example, the width of the mark 0S11 of the 0MR sheet 0S1 can be changed by clock C.
A counter is operated by counting the number of LKs, and outputs one clock pulse if the detected width of one mark 0S11 is a predetermined width. This clock pulse CLK is counted by a counter 17.

The 0MR identification circuit 19 detects the 0MR sheet 0 shown in FIG.
In the case of S1, there are six marks 0S11 at the tip, so in this example, if the counter 17 counts S6'' within one cycle of the reading signal, it is determined that it is a 0MR sheet and the control is performed so that the 0MR mode is specified. Part 18 to level S11
Output as /' signal.

When the 0MR mode is entered, the 0MR sheet 0S1 is moved by a predetermined pitch and the signal VID is
Using the detection signal of the mark 0S13 shown in FIG. 1A as the basic position, the position of the written mark 0S16 is identified and the destination is read out.

Next, when the facsimile original 0S2 is sent in, as described above, when it is detected by the sensor 9, the reading sensor 11
The read signal VID read out, binarized, and output is
This is the surface of the back panel, 0MR sheet 0S1
Each mark 0S11 is not detected, and after one scan, the 0MR identification circuit 19 outputs a signal indicating that it is a facsimile document to the control section 18 as a signal of level SO''.Thereby, the control section 18 outputs an image signal It enters processing mode,
While moving the original 0S2 by a predetermined pitch, the clock CLK and read signal VID received from the timing control circuit 14 and the binarization circuit 13 are sent to, for example, a run-length encoding circuit (not shown), and a facsimile signal is created. As described above, according to the present invention, the OMR sheet is provided with a notch, and when the notch is detected, the leading edge of the OMR sheet is read out, and in the case of a family manuscript, the leading edge is not read out. In addition, the output of this reading sensor is used as a reading sensor that identifies each medium and creates an image signal or an 0MR reading signal, so the path length is shortened, and furthermore, it is possible to Since the image information written on the document is not read out at the time of detection by the sensor, a facsimile apparatus is realized which has the effect that image information of all areas of the document is read.
