Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a facsimile machine, and more particularly to a facsimile machine having a function of manually performing a1 scanning when taking an image IFI.

[Technical background of the invention and its problems]

A facsimile is a system that reads an image on the document surface, modulates it, transmits it via a transmission system (mainly using a telephone line), and demodulates the received signal on the receiving side and records it as an image. Generally, sheet-like originals are targeted for reading, and devices that read the original while automatically transporting the original (so-called paper feeding) have been put into practical use. That is,
This is a device that automatically reads images not only in main scanning but also in sub-scanning.

However, recently there has been a demand for transmitting not only sheet manuscripts but also manuscripts such as book notebooks and newspapers by facsimile. In such a case, sub-scanning must be performed manually by placing the image reading unit against the document and moving it in one direction. When sub-scanning is performed automatically, the document is generally inserted into the device with the beginning of the text (first line) first. On the other hand, with manual sub-scanning, due to the habit of reading books, etc., it is inevitable to
It is thought that the person often stands up with the part facing upward, and in that state moves the uniform reading section from the bottom to the top. That is, reading starts from the last line of the document, and finally reads the first line.

Therefore, if transmission is performed in the reading order as in the case of automatic sub-scanning, reception will be recorded from the line after R on the receiving side.

Therefore, when the transmission speed is slow, there is a problem in that it takes a long time until the beginning of the document is recorded. For example, in the G2 mode, the first part of the document will not be recorded on the receiving side until three minutes after the start of reception, and depending on the content of the transmission, the content will not be known until the recording is completely completed. This is a major drawback in facsimile, whose greatest feature is immediacy, and a countermeasure is desired.

[Purpose of the invention]

The present invention has been made in view of these conventional problems, and an object of the present invention is to provide a facsimile machine that can transmit a document from the first line even when manually performing sub-scanning, and that ensures immediacy. do.

[Summary of the invention]

In order to achieve this object, the present invention
I In a facsimile machine that has a function to manually perform sub-scanning of main scanning and sub-scanning in a reading operation, a first facsimile machine that sequentially transmits image signals from an image reading section starting from the signal of the first scanned main scanning line is used. The present invention is characterized in that it includes a transmission order switching means for switching the mode and a second mode in which signals are transmitted sequentially starting from the last read main scanning line signal. Here, if the facsimile device also has a function of automatically performing sub-scanning, the transmission order switching means is in the first mode when sub-scanning is performed automatically, and the transmission order switching means is in the first mode when sub-scanning is performed manually. In some cases, it is desirable to have a configuration that enables the second mode.

〔Effect of the invention〕

According to the present invention, even if sub-scanning is performed manually, regardless of whether the reading is performed from the first line or the last line of the document, the first line, that is, the first main scan It can be transmitted from the line signal. Therefore, since the receiving side can always record the reception from the first line of the manuscript, it is possible to grasp the contents of each page of the manuscript sequentially before recording it to the end, which has the advantage of providing immediacy. .

The image reading section 1 includes an operation section 4 consisting of a power button 4a, a reading button 4b, a reset button 4C, and a send button 4d, and a display section 5 consisting of display lamps 58-5d corresponding to the buttons 4a-4d. There is. In this example, the image reading unit 1 and the transmitting unit 2 are electrically connected via a cable 6 that cannot be attached or detached, and power is supplied from the transmitting unit 2 to the image reading unit 1 via this cable 6, and the image is transmitted through the cable 6. Control of the reading section 1 and transfer of image signals from the image reading section 1 to the transmitting section 2 are performed. In addition, in consideration of portability, AC

Battery pack 8 is appropriately charged by charger 9. Furthermore, the output signal from the transmitter 2 can also be supplied to a receiver, which will be described later, via the cable 10. This cable 10 can be attached or detached at either end on the transmitting section 2 side or on the receiving section side.

Next, detailed configurations of the image reading section 1 and the transmitting section 2 will be explained. FIG. 3 shows the image reading section 1 and the transmitting section 2 in the first
FIG. 4 is a cross-sectional view of the superimposed state shown in the figure.

As shown in FIG. 3, the image reading unit 1 has a first case 11 with an open bottom, and an image sensor 12 is installed above the case 11.
A rod lens 13 (gradient index lens) called a SELFOC lens (trade name) is arranged on the front surface (lower side) of the lens 2.

The image sensor 12 is constructed by arranging photoelectric conversion elements using amorphous silicon as a photoelectric conversion film in a line of 7 layers, and is called a contact type image sensor. It is a one-dimensional image sensor with approximately equal array length. The lens 13 forms a so-called equal-magnification imaging system that forms an image of the document surface on the image sensor 12 in a one-to-one size. Further, a light source for illuminating the document surface is located near the light output end of the rod lens 13 in the first case 11 and is parallel to the arrangement direction of the photoelectric conversion elements in the image sensor 12. , a fluorescent lamp 14 attached to sockets 15a, 15b is provided.

Furthermore, the image sensor 12. A paper feed for transporting the original onto shafts 178.17b provided parallel to the rod lens 13 and the fluorescent lamp 14 and at a predetermined interval from each other so as to slightly protrude from the opening of the first case 11. Roller 17a.

17b is supported. Further, an additional shaft 16c is provided above the first case 11 and parallel to the shafts 16a and 16b, and a rotary encoder (not shown) is mounted on this shaft 16c for detecting the amount of document transfer. is installed. Ladder wheels 18a to 18c are attached to one end side of the shafts 16a to 16c, and a ladder chain 19 is stretched across these ladder wheels 188 to 18c.

On the other hand, the transmitter 2 has a second case 21 that is separate from the first case 11 in the image@reading 8I11. Inside the second case 21 are shafts 22a and 22 located opposite to the shafts 16a and 16b that are arranged in the first case 11.
b, and paper feed rollers 23a, 23b are supported by these shafts 22a, 22b. In this example, there are a plurality of paper feed rollers 23a and 23b, each of which is attached to the shafts 22a and 22b at predetermined intervals. Also,
A motor 24 serving as a drive source for automatic document feeding is arranged inside the second case 21 . This motor 24
The rotation of the teeth *25 and m connected to the shaft of the motor 24
Via wheels 26, 27, it is transmitted to a gear 28, which is arranged coaxially with the paper feed roller 17a in the first case 21. Note that the paper feed roller 17a is further provided with the gear 28.
A gear (not shown) is coaxially provided on the opposite side.
Rotation is transmitted from the gear to the shaft 16C that supports the rotary encoder via another gear (not shown).

Furthermore, a switch 20 is provided at the top of the second case 21 to detect that the image reading section 1 is superimposed on the transmitting section 2 .

In the above configuration, when reading an image on a sheet-like original A, as shown in FIGS. 2 on the second case 21 of No. 2. In this state, one end of the sheet document A is sandwiched between the paper feed rollers 17a and 17b on the image reading section 1 side and the paper feed rollers 23a and 23b on the transmission section 2 side, and the power button 4a and the read button 4 are pressed.
When b is pressed, the motor 24 is energized and driven via the cable 6, and the gears 25-26-27-28-paper feed roller 1
The rotation is transmitted through the path 7a, and the ladder chain 1
The rotation is transmitted through the path of the ladder wheels 18a to 18c to 18b through the paper feeding roller 17a.
, 17b rotate. In this way, the document A is transferred to the paper feed roller 17a.

The document A is transported while being sandwiched between the document A and the paper feed rollers 23a and 23b, and at the same time, the fluorescent lamp 14 is turned on, so that the surface of the document A is illuminated.

In this process, the image on document A is transferred to the Rondo lens 13.
It is optically read by the image sensor 12 via the image sensor 12, and an image signal is output from the image sensor 12. This image signal is sent to the transmitter 2 via the cable 6.

On the other hand, as shown in FIG. 2, if the original to be transmitted is today, the image reading section 1 is mechanically separated from the transmitting section 2.
Move like an arrow over the page you want to send today. Thereby, the image of that page is similarly read by the image sensor 12.

FIG. 5 shows the configuration of the circuit section of the transmitting section 2 in relation to the image reading section 1, and FIG. 6 is a flowchart showing its operation. An image signal from the image sensor 12 in the image reading section 1 is input to the CPU 43.

A signal from an automatic/manual sub-scanning determining means 41 including the switch 20 and a signal from the rotary encoder 42 are input into the CPU 43 .

The image signal from the image sensor 12 is converted into a digital signal by an A/D converter within the CPU 43 and then input to the address conversion circuit 45 .

The address conversion circuit 45 converts the read address of the image memory 46 that stores the input image signal based on the signal from the automatic/manual a1 scan determining means 41. That is, the image memory 46 is constituted by a RAM having a capacity that can store image signals for one document, for example, and when image reading is automatic sub-scanning as shown in FIG. The image signals stored in the memory are read out in the same order as when they were written, that is, from the signal of the main scanning line read first by the image reading section 1, and in the case of manual sub-scanning as shown in FIG. The signals are read out in reverse order, that is, starting from the signal of the main scanning line read last by the image reading section 1. The image signal read out from the image memory 46 in this manner is subjected to signal processing such as data compression and encoding in the same manner as in conventional facsimile machines, and then is suitable for transmission by a modem 47 such as a phase modulation signal, quadrature amplitude modulation, etc. The modulated signal is then appropriately amplified and sent to the acoustic coupler 3.

The acoustic coupler 3 is set in a telephone (not shown) and converts a modulated signal input from the modem 47 into an acoustic signal.

As a result, the modulated signal is sent from the telephone to a telephone line (mainly a public telephone line), and is then transmitted to the facsimile machine of the other party.

Note that the present invention is not limited to the above-described embodiments; for example, in the embodiment, when switching the transmission order (address conversion), the image reading section 1 and the transmitting section 2 are overlapped using the switch 20. Although it is determined whether sub-scanning is automatic or manual by detecting whether the paper feed motor 24 is being driven (whether or not current is flowing through the motor 24) Or, using the signal from the rotary encoder 42, the paper feed roller 23a on the transmitting section 2 side.

The determination may be made based on whether or not 23b is rotating, and further based on the presence or absence of the document A between the paper feed rollers 17a, 17b on the image reading section 1 side and the paper feed rollers 23a, 23b on the transmission section 2 side. Furthermore, instead of switching the transmission order depending on whether sub-scanning is automatic or manual, for example, a transmission order designation switch 4e is provided as shown in FIG. 1, and the presence or absence of address conversion can be designated by a signal from this switch 4e. It's okay. A flowchart in that case is shown in FIG.

In addition, the present invention can be implemented with various modifications without departing from the gist thereof.
