Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a device for partially transmitting image information in a facsimile machine in which an original is placed on a contact glass and the image information is read.

[Prior art]

A conventional facsimile partial transmission device of this type is shown in FIG. Figure 1 shows the conventional 77 comb i
FIG. 17 is a perspective view showing the appearance of a No. 17 partial transmission device. In the figure, 1 is a facsimile transmitter, 11 is a contact glass 12 to 17 is a plurality of sub-scanning side lever feet provided in parallel to the sub-scanning direction for partially transmitting image information, and in this example, 6 It is constructed so that it can slide in the direction shown by arrow 3 in the figure. 2 is an original, and this original 2 is placed on the contact glass 11. After this, a document holding lid (not shown) is closed so that the lower surface of the document 2 can be read.

Next, the operation of the conventional facsimile partial transmission device shown in FIG. 1 will be described. First, each of the sub-scanning side levers L12-17 is manually set to the position shown in FIG. Each of the sub-scanning side levers 12 to 17 is arranged in a line in the direction shown by the arrow 3 in the figure, and has a bearing portion 41 shown in FIG. 2 for freely sliding manually. Similarly,
Each of the sub-scanning side levers 12 to 17 has an actuator 42 shown in FIG. 2 that projects inside the transmitter 1.

The optical reading device 5 shown in FIG. 2 is equipped with a slide bearing 51 at the front end, and this slide bearing 51 is inserted into a slide rod 52 fixed to the main body of the device, and the slide bearing 51 is inserted into a slide rod 52 fixed to the main body of the device. The document 2 is read by moving in the direction indicated by , that is, in the sub-scanning direction. This optical reading device 5 is equipped with seven sensors 43 shown in FIG. 2, arranged from the left side, in order to detect the position of the actuator 42 of each of the sub-scanning side levers 12 to 17. A control circuit (not shown) is configured so that each time each actuator 42 of each of the sub-scanning side levers 12 to 17 is detected, the mode is switched between two modes: start of reading and stop of reading. That is, [IJ
, r3J, and r5j, connect and combine them, transmit them, and output a copy 7 as shown in FIG.

Since the conventional 7-axis partial transmission device is configured as described above, it can only perform partial transmission in the sub-scanning direction. or extra image information rl'J, "'
3°", "5'" and "1"", [3"J, r5'
Even when it says J, do you transmit it as is, or
An overlay sheet (not shown) is attached to the contact glass 11.
There was a drawback that it was necessary to perform a complicated operation to mask these as extra image information.

[Summary of the invention]

This invention was made with the purpose of rectifying the above-mentioned drawbacks of the conventional devices. By providing two levers on the main scanning side parallel to the main scanning direction, which is perpendicular to the main scanning direction, partial transmission in both the main and sub scanning directions can be easily performed simultaneously or independently as necessary. The present invention provides a facsimile partial transmission device that can easily perform the following operations.

FIG. 3 is a diagram showing an example of a copy made by partial transmission.

As shown in FIG. 5, 6 is a two-slow type variable resistor that constitutes each main scanning lever 31732, 31-1.32-
1 is a slider of the variable resistor 6, and each slider 31-1.
32-1 is inserted into each of the main scanning side levers 31 and 32, respectively. FIGS. 7(a) and (b) K indicate each slider 31-
There are 8 reference examples for detecting each resistance value rl * 11 of 1.32-1 and deriving the respective reading distances A and Jt for the reading distance corresponding to the overall resistance value R. ing. The position of each main scanning lever jl, 32 is detected by a position detection circuit (not shown) based on the resistance values r, , r! of each slider 31-1, 32-1. When it detects K, each reading distance! 8. ! , is calculated. Each main scanning side lever 31.32 is connected to each main scanning side lever 31°3.
The image information of the document 2 between the two ends is read, and the image information at both ends is read as a white signal without being read from the beginning, or, although it is read, this is ignored and a white signal is output. In this way, as in the example of copy 8 shown in FIG.
Inconvenient or redundant image information rl'J in manuscript 2,
r3′J, r5′J and [1-1[3”J, r
It is possible to send with 5"J (see Figure 3) as a margin.

FIG. 9 is a perspective view showing the external appearance of a facsimile partial transmission device which is another application example of the present invention, and FIG. 10 is a diagram showing an example of a copy made by partial transmission by the facsimile partial transmission device of FIG.

FIG. 10 shows a copy 9 that reads only the image information [month] of the original 2 and outputs it from a destination receiver (not shown).

As described above, in the facsimile partial transmission device according to the present invention, the features of the method of placing the original 2 on the contact glass 11 and reading it are effectively utilized, and as in the case of the self-propelling method of the original 2, Partial transmission can be easily and arbitrarily performed without using a dedicated carrier sheet or marking the document 2 itself for skipping.

This is also effective in compositing character codes such as teletex and facsimile images.

In addition, the above-mentioned through and main scanning side levers 31 and 32 are as follows:
The function of reading the image information between the main scanning levers 31 and 32 is further effectively utilized to make one of the two main scanning levers 31 and 32 effective. Set it on the front left corner part 111 of the contact glass 11, which is one end of the reading width, and move the remaining one main scanning lever 32 to the back left corner part, which is the other end of the effective reading width. By sliding to 112, the effective reading width can be variably fixed in a plurality of stages. That is, in the above embodiment of the present invention, the maximum effective reading width is A3 size, and when the main scanning side lever 32 is located at the left back corner part 112, the scanning width is 30311111. 32 to the left hand corner part 111, B4 size (256m)
, A4 size (216m) and a total of 3 levels of effective reading width.

Can be switched. For this convenience, l”Ai J rB4J is attached to the left end glass frame of the contact glass 11.
Markings may be added.

Furthermore, in the above embodiment, each of the main scanning side levers 31 and 32
The reading of the area surrounded by the plurality of sub-scanning side levers 12 to 17 has been explained, but an operation switch (not shown) is provided to reverse the partial transmission operation, and by switching this operation switch, the , Quite the opposite, it is also possible to easily skip over the portions surrounded by the main and sub-scanning side levers 31, 32 and 12 to 17, and this is also possible when combining other image information or teletexting. This is effective for compositing with.

〔Effect of the invention〕

As explained above, the present invention provides a facsimile partial transmission device in which, in addition to a plurality of sub-scanning side levers provided parallel to the sub-scanning direction of the facsimile transmitting device, a plurality of sub-scanning side levers are provided in a main scanning direction perpendicular to the sub-scanning direction. Since it has a configuration in which two main scanning side levers are provided in parallel to the main scanning side, partial transmission in both the main and sub scanning directions can be performed simultaneously or independently as necessary, with extremely simple operation. This provides an excellent effect in that partial transmission can be performed at will.
