Abstract

PURPOSE:To accurately set and print the desired part of an original by watching a liquid crystal display part and confirming a read original picture before printing is started. CONSTITUTION:In the case of reading the original, a compact copying device 1 is placed on an original D by keeping a liquid crystal panel 3 downward, and a reading key 41 is operated. Thereupon, an LED array 10 is turned on, a DC motor starts rotation, and an original reading part 5 exposes and scans the upper side of the original D. A reflected light beam from the original D is received by a CCD array 11, inputted from the array 11 to a CPU 12 in the format of data, and stored in a storing part 12a. When the device 1 is inverted, and a monitor key 42 is turned ON, the original picture in the storing part 12a is displayed on the panel 3. Thus, since an operator can confirm the read original picture while watching the panel 3 before the printing is started, when the read original picture does not correspond to the required part of the original D, a reading operation can be executed again.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a compact copying device, and more specifically, the present invention relates to a small-sized copying device, and more specifically, a document reading section that reads document image data and a printing section that prints image data on transfer paper are the same. The present invention relates to a small-sized copying apparatus that scans with a drive system and includes a storage section that stores read document image data.

<Prior art> Conventionally, the main body of a copying machine is placed on the original to be copied, the original image data is read and stored while automatically exposing and scanning the original surface, and then transfer paper is set. Small-sized copying devices have been manufactured that are capable of printing stored original image data onto transfer paper.

In order to simplify the mechanism, this small-sized copying apparatus uses the same drive system to scan the document reading section that reads document image data and the printing section that prints image data on transfer paper.

Therefore, the device has the advantages of being small, lightweight, easy to carry, and easy to operate. Therefore, it is suitably used in cases where the printer is brought to any location and selectively prints a desired portion of a wide document such as a book or newspaper.

<Problems to be Solved by the Invention> However, with the above-mentioned small-sized copying machine, when printing on the original surface, there is no means to check whether the desired part has been accurately read, and the operator has to check the print result. You can check for the first time whether the desired part has been read. Therefore, if a desired portion fails to be read, the entire process from reading to printing must be repeated, resulting in wasted time and wasted transfer paper.

In addition, since it is not possible to set the scanning area with accurate dimensions and it is not possible to monitor the scanning area, it is not possible to trim the original (copying an image that corresponds only to a specific area of the original), masking (copying an image that corresponds to only a specific area of the original) It is also impossible to perform editing functions such as copying the image of the removed area as desired.

The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a small-sized copying apparatus that can accurately print a desired portion of a document and has an editing function.

Means for Solving the Problems> The small-sized copying apparatus of the present invention for achieving the above objects has the following features:
The present invention is characterized by comprising a liquid crystal display section for displaying document image data, an area specifying means for dividing the display surface of the liquid crystal display section into desired areas, and an editing command means for causing editing to be performed on the divided areas.

Effect> According to the compact copying machine with the above configuration, before starting printing,
Since the read document image can be checked while looking at the liquid crystal display, if the display does not correspond to the desired part of the document, the user can restart the reading operation from the beginning and set the correct settings again. Furthermore, editing functions can be accurately executed by dividing the display surface of the liquid crystal display section into desired regions and performing masking or trimming operations on the divided regions.
