Abstract

PURPOSE:To perform secure reading and transmitting without generating missing places against input original copys with different sizes by outputting a scale- down read specification signal to convert a sending image information signal to the one suitable for the communication line if the width of the original copy to be input as a transmission object is larger than the predefined threshold for width or its length is longer than the predefined threshold for length. CONSTITUTION:When the original copy to be transmitted is inserted, an original width detecting division 1 and original length detecting division 2 which are composed mainly microswitches comparare with the specified values and send the results to a scale-down read deciding division 4 to determine the original sizes. After the determination, the information read from the original copy in an image information read division 3 is input in an image information thinning division 5 as a first image information signal 31 and the picture elements are thinned out to be output as a second image information signal 151 until the number of the first image information signal 31 becomes equal or same extent to the capacity of a memory division 6 if the value of a scale-down read specification signal 41 is 'H'. And it is stored in the memory division 6.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Business Application) The present invention relates to a facsimile machine, and more particularly to a facsimile machine that has a function of determining the size of an input document and automatically reducing the size and transmitting the read document.

(Prior Art) Conventionally, in this type of 77 mm device, when inputting a document to be sent, the width of the document is determined by a document width detection means that detects the spread of the guides of the feed reservoirs on both sides of the document to the left and right. However, it does not have a means to determine the length of the document. For this reason, facsimile machines that have an editing function that allows you to write text in addition to the image information of a document and send or copy it are required to reduce the image information on paper that exceeds standard specific dimensions. The determination means for this purpose is based on the dimensions of the document estimated only from the detected width of the document.

- For example, if the standard size paper is letter size (8.5 inches x 11 inches), and the guide width is set to 85 inches, the input document will be determined to be letter size and reduced. First, when a full guide width of 11 inches is specified, the size of the set original at-printer is determined (11 inches x 14 inches) and a reduction instruction is issued.

(Problem to be Solved by the Invention) However, such conventional document size determination methods do not have a means to fully judge the quality of the document, so for example, if the width of the document is 8.5 inches, which is the same as the letter size, If you have legal size paper (85 inches x 14 inches), it will be judged as letter size (85 inches x 11 inches), so you cannot specify reduction, and therefore the length of the longitudinal edge of the document will not be specified. An area of 3 inches in length and 8.5 inches in width was not read, and the problem was that image information signals in this area were often missing.

The present invention has been made in view of the above, and it is an object of the present invention to provide a facsimile apparatus having a function of reading and transmitting image information of an input document without losing all of the image information.

(Means for Solving All Problems) The facsimile device according to the present invention is capable of determining whether the width of the document input as a transmission target is larger than a predetermined width threshold, or the document length of the document written in @jJ is predetermined. an image information reading section that outputs a first image information signal read from @Kiharameki; an image information thinning section that thins out and outputs the first image information signal when the signal is output, and outputs the first image information signal as it is when the reduction reading designation signal is not output; and the image information thinning section. a storage unit that stores at least a portion of the original image information signal outputted from the original, additionally edits other information signals, and outputs the transmitted image information signal as a transmitted image information signal; and converts the transmitted image information signal into a transmitted signal that is compatible with all communication lines. and a transmitter that outputs the data.

(Example) The present invention will be described in detail with reference to drawings showing examples.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention, and FIGS. 2(a) to 2(f) show the relationship between the input document and the detection guide and the storage area of the storage unit in the embodiment of the present invention. This is an explanatory diagram showing the correspondence.

Referring to FIG. 1, in this embodiment, a document width detection section 1 detects the width of an input document and outputs a document width detection signal 11.
Then, the length of the input document is detected and the document length detection signal 2 is output.
1f! : A document length detection section 2 that outputs, an image information reading section 3 that reads image information of an input document and outputs a first image information signal 31, a document width detection signal 11, and a document length ejection signal 21. a reduction reading determination section 4 which receives the input and outputs the reduction reading designation signal 41; an image information thinning section 5 which receives the first image information signal 31 and the reduction reading designation signal 41 and outputs the second image information signal 51; , second image information signal 51
a storage unit 6 which inputs and outputs a transmission image information signal 61;
The transmitter 7 is provided with a transmitting section 7 that inputs a transmitted image information signal 61, converts it into a transmitted signal 71 suitable for a communication line, and outputs it. A document size determining means based on the document width detecting section 1, document length detecting section 2, and reduction reading determining section 4 described above is formed.

Next, the operation of the embodiment shown in FIG. 1 will be explained with reference to FIGS. 1 and 2.

When a document to be transmitted is inserted, the document width detection section 1, which is composed of a microswitch or the like, detects the width using a pair of left and right document width detection guides 8 that touch the side surfaces w and w' of the document from both sides of the document. When the width is larger than a predetermined width threshold, the high level value of the binary signal ``H#'' is set, and when it is smaller than the width threshold, the low level value of the binary signal 'L# is set to the document width. It is output as a detection signal 11.

Similarly, the document length detection unit 2, which is composed of a micro switch, etc., has two positions: a fixed position where one end of the document is fixed at right angles to both sides w and w' of the document; lol
The length between the document length detection guide 9 and the document length detection guide 9 that is in contact with the other end surface l' of the document that is approximately perpendicular to the document is detected, and when the length is larger than a predetermined length threshold, a binary signal is detected.・
- When the high level value "11" is smaller than the length threshold value, K outputs the low level value %L# of the binary signal as the document length detection signal 21.

The reduction reading judgment s4 is based on the document width detection unit ql input to this.
The original size is determined from the logical sum of l and the original length detection signal 21, and a binary signal H# or (S l, # reduction reading designation signal 41 is outputted to the one-image information thinning unit 5. .

After the above determination is made, the information read out from the original by the image information reading section 3 is sent to the first image information signal 31.
The resulting image information is input to the image information thinning section 5. In the image information thinning section 5, the value of the input reduction reading designation signal 41 is '
In the case of L#, the first image information signal 31 is output as is as the second image information signal 51 without being thinned out, and
The information is input to the storage unit 6 and stored. Further, when the value of the input reduced reading designation signal 41 is 1H'', the pixels are thinned out until the number of pixels of the first image information signal 31 becomes the same or approximately the same as the capacity of the storage section 6. The image information signal 51 is outputted as a second image information signal 51, and input to and stored in the storage section 6.

The storage unit 6 outputs a transmission image information signal 61 that is edited by adding a character information signal etc. as necessary to the second image information signal 51, and inputs this to the transmission unit 7 for modulation and band limitation. Transmission signal 71 that is processed to match the communication line
Output as .

Table 1 is a table showing the judgment conditions by the reduced reading judgment unit 4.
Ru. Here, as an example, the width threshold value for document width detection section 1 is set between 8.5 inches and 11 inches, and the length threshold value for document length detection section 2 is set between 11 inches and 11 inches.
When set between 4 inches and 4 inches, three types of original sizes (letter size 8.5 x 11 inches, cougar size 8
．． Table 1 shows the values of the original width detection signal 11 and the original length detection signal 21 and the judgment results of the reduced reading designation signal 41 for 5X14. Only when both values are 'L'
It will be "L", and if it is outside the east, it will be "H".

Therefore, in the case of the determination condition according to this example, the reduction reading designation signal 41 for the letter size becomes ``[, u'', so the first image information signal 31 of the letter size original is not thinned out. Further, since the reduction reading designation signal 41 for the legal size and printer size becomes 'H', the first image information signal 31 of the legal size original and the printer size original are both thinned out.

Next, regarding these sizes in this example, the relationship between the document width detection guide 8 and the document length detection guide 9 of =9− and the input document, and the status of the effective storage area of the storage unit 6 based on the above-mentioned determination results are determined in a second manner. This will be explained using figures. Figure 2(a)l(b) and Figure 2(C).

(d) and FIGS. 2(e) and (f) respectively show these situations for an N letter size 8.5 x 11 inches and a zigal size 85 x manuscript.

In the figure, the shaded area indicates an area that is effective as image information.

When the letter size original (8.5 x 11 inches) is 12N, it is output as is without being thinned out, so the storage unit 6
Although the storage area 14A occupies the entire storable area 13, there is no missing part of the image information of the original 12&. When the length direction of the letter size original 12A is extended, or when the original size is one gal size (8.5 x 14 inches) 12B, the entire storage area 14B of the storage unit 6 is scaled down due to thinning, and both sides of the storage area 130 are left blank. However, there is no missing part of the image information of the original 12B. In addition, a printer size document (11X
14 inches) 12C, the entire storage area 140 of the storage unit 6 is scaled down and the storage area 1 is
However, there is no missing part as image information of the document 12C.

Even if the sizes of the input documents differ in this way, if the image information after thinning processing by the reduction reading specification is within the storable area 13f of the storage unit 6, the image information will be valid for the document whose size does not exceed. As a result, there are no missing parts at all.

In this embodiment, a microswitch is used as an example of the constituent elements of the document width detection section 1 and document length detection section 2, but the same effect can be achieved even if a pressure detection type or a photoelectric detection type is used. Effects can be obtained.

(Effects of the Invention) As described above, the present invention detects and determines the size of an input document two-dimensionally, so that even if the size of the input document differs, there will be no missing parts as image information. This has the effect of ensuring reliable reading and transmission.
