JPS617768A - Device for designating read area for original reader - Google Patents

Abstract

PURPOSE:To eliminate inconvenience caused when a specific area is designated with a mark in an original by operating the original based on a designated signal outputted from a designating device. CONSTITUTION:When a platen cover 4 is closed once, a specific area designation key is turned on and an information signal detecting a position outputted from knobs 13a, 13b, 14a, 14b is inputted to a control section 19 and stored. When the operator opens a cover 4, turns down the original 1, places the original to a prescribed position, closes the cover 4 again and then turns on a transmission key 5, a prescribed facsimile operation is executed. A program converting automatically the position information of the part A inputted to a measuring section 19 in this case to a corresponding position is executed at the turn-over of the original 1. Thus, only a part corresponding to the part A is read by CCD15 and after coding by a coding section 16, the result is modulated by a MODEM18 and transmitted to a line 17.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a reading area designation device for a document reading device, and in particular, to a reading area designation device for a document reading device, in particular, a designation device such as a knob, a key switch, etc. that moves outside the document placement range is provided. The present invention relates to a reading area specifying device for a document reading device that specifies a reading area.

[Conventional technology]

Facsimile machines, digital copying machines, document readers (connected to combinations, printers, etc.) are equipped with document reading devices that read documents completely photoelectrically. With this document reading device, it is possible to specify a specific area within a document (for example, an individual's memo area, a secret area), and to read outside the specified area and not allow that area to be read, or to improve the image quality by increasing the reading density. There are some things that can be done to improve the quality of the image, such as specifying only a photographic area and performing halftone processing on that area. Conventionally, methods for specifying partial areas for such processing include placing specific marks in the document, placing a transparent sheet with the marks on top of the document, and specifying the specific partial area. Alternatively, a method has been used in which instructions are given using color marks.

[Problem that the invention seeks to solve]

However, with the above-mentioned method of specifying partial regions,
It is necessary to read the marks attached to the document and recognize the pattern, but there is a risk of false detection depending on the accuracy of the pattern recognition.

In addition, if the area designation mark and the scanned information are the same, the information will be read as a partial area designation mark and the information will not be read.Additionally, if the mark is set within the document, the area that can be used freely within the document will be reduced. There is a serious problem if you do this. Furthermore, the method of adding color marks has the disadvantage that partial areas cannot be specified for full-color originals.

[Means and effects to be solved by the invention] The present invention has been made in view of the above-mentioned problems, and has been made in order to avoid the inconveniences and disadvantages that occur when specifying a specific partial area using marks in a manuscript. - A designation means for designating a predetermined partial area on the document in the vertical and horizontal directions near the part where the document is placed is provided, and the document reading operation is controlled based on a designation signal output from the designation device. The present invention provides a reading area designation device for a document reading device.
