Abstract

PURPOSE:To increase the preserved quantity of data by using effectively the capacity of a memory, by deleting an input to the memory when the read information of a line sensor is vacant information. CONSTITUTION:The picture information of an original 17 is read by every line by the line sensor 5, and when it is judged that the read information is not completely vacant over entire one line, it is stored on the memory 9. When the read information is judged as the vacant information, it is judged that vacant exists over a prescribed number of lines, and when a result is NO, the vacant information is also stored on the memory 9, and when it is YES, the vacant information is deleted by a vacancy deleting means 13, not being stored on the memory 9, and the information of next line is read. In such way, it is possible to prevent the capacity of memory 9 from being used wastefully, and to store the information as much as possible. Also, at time of printing, it is possible to print a large amount of information in a small space. Also, when the line sensor 5 reads the vacant information, and next, it reads an image substantially, it is possible to store a label at the forefront of the image.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a copying apparatus.

Conventional Copying Machines in general have functions such as reduction and enlargement, but they only copy the original image as it is.

Problems to be Solved by the Invention As a result, extra blank spaces are stored, resulting in insufficient memory capacity. There is also a problem in that extra printing space is required when printing.

Means for solving the problem A line sensor that moves in the sub-scanning direction and optically reads image information in the main scanning direction line by line, a memory that stores the input of this line sensor, and a memory that stores the input of this line sensor. and a blank deletion means for deleting input to the memory when line read information from the line sensor is blank information.

Therefore, the line sensor reads image information line by line, and when the line read information is blank information, the blank information is deleted by the blank deletion means and stored in the memory. Also, fill in any extra blank spaces and print.

Embodiment A first embodiment of the present invention will be described with reference to FIGS. 1 to 4. As shown in FIG. 1, a display 3 is connected to the system control unit 1 via a display control unit 2, and a line sensor 5 such as a COD image sensor is connected via a sensor drive unit 4. , a printing section 7 is connected via a driver 6, and a memory 9 is further connected via a memory control section 8. The sensor drive section 4 and the driver 6 each have a movement amount sensor 1.
0 and 11 are connected, the line sensor 5 is connected to the memory 9 via the data processing circuit 12 and the blank deletion means 13, and the memory 9 is connected to the printing section 7 via the data processing circuit 14.

Next, as shown in FIG. 2, a case 15 of a size that can be held by hand and has openings at both ends is provided.

At one end of this case 15 is a printing section 7 such as a thermal head.
is built in, and the line sensor 5 is built in at the other end. Further, the movement sensors 10 and 11 are, for example, rotary encoders, which detect the amount of movement of the case 15 with respect to a document or printing paper, and are built into both ends of the case 15, respectively. Furthermore, case 1
The display 3 and a mode switch 16 for switching between reading mode and printing mode are provided on the side surface of 5. The other electronic circuit elements shown in FIG. 1 are built into the case 15.

In this configuration, when reading the image of the original,
The mode switch 16 is switched to the reading side, and the case 15 is moved along the top of the original 17 with the print section 7 side facing up, as shown in FIG.

In the case of text, the direction of movement is the sub-scanning direction, in other words, the line spacing direction. At this time, the movement amount sensor 10 detects the movement of the case 15 with respect to the original 17! The rlIl amount is detected and a detection signal is output, and the sensor drive unit 4 drives the line sensor 5 in response to this detection signal.

The digital signal outputted by the line sensor 5 is stored in the memory 9 via a data processing circuit 12 and a blank deletion means 13. The operation of the blank deletion means 13 will be described in detail later. For printing, the mode switch 16 is switched to the printing side, and the case 15 is moved along the top of the printing paper with the printing section 7 facing down. At this time, the movement amount sensor 11 detects the amount of movement of the case 15 with respect to the printing paper and outputs a detection signal, and the driver 6 drives the printing section 7 in response to this detection signal, and the printing section 7 reads from the memory 9. Printing is performed on printing paper based on the data called out via the data processing circuit 14.

Next, the effect of the blank deleter 1130 will be explained. FIG. 4(a) shows image information of the document 17.

As you can see, there is a blank space between the three columns of articles. Therefore, as shown in the flowchart of FIG. 3, the line sensor 5 reads the image information of the document 17 line by line, and stores the read information in the memory 9 when it is determined that the entire line is not blank. When it is determined that the read information is blank information, it is determined whether or not it is blank for a predetermined number of lines or more. If NO, the blank information is also stored in the memory 9, and if YES, this blank information is The data is deleted by the deletion means 13, and the information of the next line is read without being stored in the memory 9. If the predetermined number of lines is 1, for example, the image information of the document 17 shown in FIG. 4(a) is stored with all blanks removed as shown in FIG. 4(b). Therefore, printing is also performed with the image shown in FIG. 4(b).

This prevents the capacity of the memory 9 from being wasted.
Can store more information.

Further, when printing, a large amount of information can be printed in a small space.

Further, when the line sensor 5 reads blank information and then substantially reads an image, a label can be stored at the beginning of the image. The positions of these labels are indicated by arrows LO, LL, and L2 in FIG. 4(b). Thereby, even if blank spaces are deleted when calling up information in the memory 9, it is possible to easily locate the beginning of the segmented information.

As shown in the flowchart of FIG. 5, each time one line is read, the read information is stored in the memory 9.
When this information is not blank, set the next line memory address of the line sensor 5 and save the information that has just been memorized. Set the current line memory address. Therefore, when the next information is stored at this current line memory address, the previously stored blank information will be erased. As a result, it is possible to achieve the same purpose as in the embodiment described above, but since the read information of one line is stored continuously, the processing is faster.6 Next, the second embodiment of the present invention will be explained based on FIGS. 6 to 8. The same parts as in the previous embodiment are designated by the same reference numerals, and the description thereof will be omitted. As shown in FIG. 7, a scroll key 1 is provided on the side of the case 15, which is an operation unit for scrolling the screen of the display 3 in the line spacing direction.
8, and a deletion switch 19 for operating the blank deletion means 20.
and is provided.

This blank deletion means 20 is a memory 9 as shown in FIG.
It is connected to the.

Therefore, as shown in the flowchart of FIG. 8, when the line sensor 5 reads each line, the contents are temporarily stored in the memory 9. The read information is displayed on the display 3, and the screen changes by operating the scroll key 18. Then, by calling out not only the blank information but also unnecessary information to the display 3 and activating the deletion switch 19, the blank deletion means 20 is activated and the information appearing on the display 3 is deleted from the memory 9, and other necessary information is information is stored in the memory 9.

Effects of the Invention Since the present invention is configured as described above, the line sensor reads image information line by line, but when the line read information is blank information, this blank information is deleted by the blank deletion means and stored in the memory. As a result, the amount of data stored can be increased by effectively using the memory capacity, and extra blank spaces can be filled up for printing.
