Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a facsimile transmission device that performs automatic destination transmission and interlaced scanning.

In the past, various facsimile transmitters having an automatic address sending function and an interlaced scanning (partial feed) function have been proposed, but the most common type of facsimile transmitting apparatus that employs an interlaced scanning function is the drum scanning type, which does not require automatic feeding. It was not possible to incorporate a paper mechanism to automatically process multiple sheets of originals. In addition, facsimile transmission devices that employ an interlaced scanning function using a plane scanning method use one document feeding table for each document, and this document feeding table sets the interlaced position, so automatic feeding is possible. The paper machinery had become extremely large-scale.

In addition, the edge of the document itself is marked with a drop-out color on either the parts that do not need to be sent or the parts that need to be sent, and this mark is read by a special optical reading means, and the parts of the document that do not need to be sent are scanned with interlaced scanning ( There is also a method to perform fast forwarding), but in this case, you must mark the document, so
The same manuscript could only be sent once. Therefore, for example, if you attach the original copy of your family register to the facsimile transmitter in the city hall main building and send it, and then receive the extract of your family register at the city hall branch office where you applied,
Since it is not possible to mark original copies with drop-out colors, this method can only be used for a limited number of manuscripts.

The present invention solves these various problems by attaching automatic destination transmission information and interlaced scanning (partial feeding) information to a document carrier sheet, and making automatic paper feeding possible using an automatic paper feeding mechanism. The purpose of this invention is to provide a facsimile transmission device.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a plan view showing an embodiment of a document carrier sheet used in the facsimile transmission device of the present invention, and FIG. 2 is a side view thereof. Further, FIG. 3 is a block diagram showing an embodiment of a facsimile transmitting apparatus of the present invention which performs facsimile communication using such a document carrier sheet.

The original carrier sheet 1 is a relatively thick mount 1.
a, and a transparent film 1b attached to a portion slightly offset from one end of the mount 1a. The mount portion 1d slightly exposed from the pasting portion 1c serves as the leading edge of the carrier sheet 1 during feeding, and is intended to facilitate engagement with the feeding roller. The corner of this tip is cut to prevent it from curling up after long-term use. Further, the inside of the mount 1a is formed to have a high friction surface, which prevents the original from shifting or falling off within the carrier sheet 1 during feeding. In addition, the pasting part 1c includes a sheet symbol field 1f for operator identification;
Sheet symbol mark fields 1g, 1g', 1 for detecting what kind of sheet the facsimile transmitter is
In this example, for convenience of explanation, there are five types of sheets A to E (here, the sheet symbol is "A"), and therefore, in order to identify the five types of sheets, The following explanation assumes that three code mark fields 1g, 1g', and 1g'' are provided.Furthermore, on the mount 1a of the sheet 1, memories 1h are printed at equal intervals in the sub-scanning direction in drop-out color. This memory 1h corresponds to the memory of an interlaced scan (partial feed) position setting switch of a facsimile transmitter, which will be described later.

Original carrier sheet 1 configured as above
While checking the memory 1h of the document carrier sheet 1, select the interlaced scanning position setting switch installed on the operation panel of the facsimile transmitter. Set 2. There are five types of switches 2, A to E, corresponding to the type of seat. When the seat symbol is "A", the switch 2-A for "A" is set. The switch 2-A is slidably provided with a large number of interlaced scanning designating knobs 2a each of which is a reed switch, and the operator adjusts the knobs 2a to the memory 2b while looking at the memory 1h of the document carrier sheet 1. In the following, the sheet symbol "B" is switched to switch 2-B, and the sheet symbol "C" is switched to switch 2-c.Although not shown in the figure, interlaced scanning of multiple documents can be set in advance by the same operation. .

Next, press switch ``A'' from switch 3 for specifying five types of sheet symbols A to E, and press switch 3-
The sheet symbol "A" signal from A is converted to code conversion circuit 4.
The signal is converted into a binary signal and input from the gate circuit 5 to the address input terminal of the memory circuit 6, which is represented by a RAM. Next, one of the designation buttons 7a to 7j of the transmission destination designation switch 7 of this sheet "A" is pressed, and the destination designation signal is input to the data terminal of the storage circuit 6, and the predetermined address "A" is inputted to the data terminal of the storage circuit 6. ” The telephone number or line designation number of the destination is stored.

Next, the document carrier sheet 1 is fed to the reading/scanning device 8 by sub-scanning drive rollers 9 and 10. In the reading/scanning device, marks 1g, 1g', 1g'' are detected by an optical reading means for reading and scanning the image information of the document or by a special mark detection means.These mark detection signals are sent to the address of the memory circuit 6 through the gate circuit 5. Since the voltage is applied to the terminal, the memory circuit 6
The telephone number etc. of address "A" are stored in the line selection circuit 12 represented by a latch circuit, and connected to the designated lines 13a to 13j.

On the other hand, the clock signal of the timing clock oscillator 14 is frequency-divided by a frequency divider 15 to a predetermined value. The frequency-divided output of the frequency divider 15 is a constant speed clock output signal 15a for obtaining a normal sub-scanning speed, and a high-speed clock output signal 15b for sub-scanning feeding unnecessary portions of the document at high speed. Initially, an AND gate circuit 16b is opened by a flip-flop circuit (referred to as an F.F circuit) 17, and a high-speed clock pulse is passed through an OR gate circuit 19 to a power amplifier 20.
After being amplified by , it is applied to the sub-scanning motor 21 . Therefore, rollers 9 and 10 rotate at high speed and feed document carrier sheet 1 at high speed. Further, the drive source for the sub-scanning motor 21 is also supplied to an interlaced scanning detection belt device 22 at the same time.
The interlaced scanning detection belt device 22 connects an endless belt 22c to which three permanent magnets 22d, 22d', 22d'' are fixed at equal intervals between two pulleys 22a and 2.
2b. Pulley 2
2a, 22b, permanent magnets 22d, 22d', 22
d" and the endless belt 22c have sufficient width to cover the entire range where the five switches 2-A to 2-E are installed. Therefore, the drive pulley 22a rotates at high speed. magnet 22
When d and the first knobs 2a to 2e are close to each other, the knobs 2a to 2e, which are reed switches, turn ON, and the detection signal is transmitted to each switch 2-A to 2-e.
AND gate circuits 23a to 23 corresponding to 2-E
e. However, sheet symbol detection circuit 1
1, since the enable signal is applied only to the AND gate circuit 23a, only the interlaced scanning designation signal of the gate circuit 23a, that is, the switch 2-A, is input to the F/F circuit 17 through the OR gate circuit 24. The F/F circuit 17 is switched by this signal and the AND gate circuits 16b to 16a are switched.
The constant speed clock signal 15a of the frequency divider 15 is applied to the sub-scanning motor 21. By the above operation, the second knob 2
The feed speed is switched each time, such as high-speed feed again when the third knob 2a is detected, and constant-speed feed when the third knob 2a is detected.

By repeating the above operations, the portions of the document to be sent that do not need to be sent are interlaced scanned at high speed.

Further, the read image signal of the original is sent to the modulation circuit 25 by a carrier signal from the carrier signal oscillator 26.
The signal is modulated and outputted from the output terminal 27 as a facsimile image signal.

In addition, switches 2 for setting interlaced scanning positions are prepared for each type of document carrier sheet, and the interlaced scanning detection belt device 22 detects the positions set by all switches 2-A to 2-E. The interlaced scanning position signal for only the relevant sheet is selected from among all detection signals, and the sheet symbol designation switch 3 outputs the set position of the switch 2 using means such as a potentiometer, and this output signal is stored in the memory. By doing so, the same purpose as the present embodiment can be achieved using only one switch 2.

It is also possible to increase the number of output types of the frequency divider and change the reading scanning density depending on the type of sheet, and it is also possible to change the reading scanning density depending on the type of sheet, and it is also possible to do this without using a document carrier sheet with a memory as an interlaced scanning position setting means. It is also possible to configure the document carrier sheet to be applied directly to a setting switch to set the transmission unnecessary section.

As described above, the present invention includes a sheet symbol detection means for detecting a sheet symbol provided on a document carrier sheet, a storage means for storing the transmission destination of each document carrier sheet in each address before scanning, and interlaced scanning position setting means for setting an interlaced scanning position of a sheet; and a sheet symbol signal detected by the sheet symbol detection means of the document carrier sheet to call the transmission destination of the sheet; The system detects the interlaced scanning position and sends the unnecessary portions at high speed.

Therefore, even if you are sending multiple originals, you can put them in each original carrier sheet and set the transmission destination and interlaced scanning position in advance, and then you can load them into the automatic paper feeder regardless of the order in which they are set. You can send automatic messages. The fact that paper can be set in the automatic paper feeder regardless of the order in which the devices are set greatly reduces the burden on the operator and speeds up office processing.
