Description

Description: TECHNICAL FIELD The present invention relates to a copying machine that performs copying by designating an area such as a copy area or an erase area of a document.

<Outline of the Invention> A copying machine according to the present invention is a number display body including at least four segments forming a parallelogram, such as a number display body composed of so-called Japanese characters, when the number of copies is input from a ten-key pad. And a region designation means for designating a copy region or an erased region of a document as the position of the left and right ends or the front and rear ends of the rectangle or both of
When the position of each end should be specified by this area specifying means, which end of the area should be input by blinking the end of the specified area, for example, the segment at the corresponding position. It is an area designating device for displaying a key.

2. Description of the Related Art An electrophotographic copying machine capable of selectively copying or erasing a part of a document image has conventionally been designed to specify the area as coordinates.

FIG. 3 is a diagram showing a document table of such a copying machine.
When designating a hatched area, the left end of the area is input as coordinate X1 and the right end is input as coordinate X2. Similarly, the front end is input as the coordinate Y1 and the rear end is input as the coordinate Y2 by reading the scales provided around the document table and inputting using the ten keys.

Such a conventional copying machine uses L1 (left end), L2 (right end), and H as methods for displaying the type of the coordinate currently being input.
Symbols such as 1 (front end) and H2 (rear end) are displayed, but in such a method, it is possible to visually determine which end of the region the coordinate to be input corresponds to. It had the drawback of being difficult to understand.

<Object of the Invention> An object of the present invention is to provide an area designating device in a copying machine, which can easily visually recognize the end of the area to be designated when designating an area such as a copy area or an erase area. To provide.

<Structure and Effect of the Invention> The present invention is a copying machine which includes at least four segments forming a parallelogram and which is provided with a numeral display for displaying the contents of a numeral input from a ten-key pad. Area specifying means for specifying the area such as the area as the position of the left and right edges or the front and back edges of the rectangle, or both,
When the position of each end is to be specified by the specifying means, display means for displaying the end position in correspondence with the four segments is provided.

With the above-described configuration, among the number display bodies that display the numeric contents from the numeric keypad, the areas such as the copy area and the erase area are configured according to the display states of the four segments forming the parallelogram. The end can be represented, and the end position to be input can be easily visually grasped. Therefore, it is possible to prevent a simple mistake such as inputting the coordinates of an incorrect position.

<Embodiment> FIG. 2 is a diagram showing each segment constituting the numeral display of the copying machine according to the embodiment of the present invention.

The numeric display has so-called Japanese character segments arranged for three digits, and can display a three-digit numerical value. This display body displays, for example, the number of copies input from the ten-key pad or the total number of copies when a key operation for maintenance is performed. The segments 10, 11, 12, and 13 provided between each of the three-digit day character segments are 3
Represents the copier body with part of the digit character segment of the digit. That is, as shown in the date character segment 3, when the seven segments forming the date character are represented as a to g, the copying machine body has the third digit a, f, e, d and the second digit a, Along with the d segment and the first-digit a, b, c, and d segments, the main body of the copying machine is represented by the segments 10 to 13. A segment 4 provided on the upper portion represents an automatic document feeder, a segment 5 represents a paper output portion for copying, and segments 6, 7, 8, and 9 represent paper feeding portions for copy paper. The triangular segments in the drawing are used to selectively display each of the above-mentioned segments and to display the stop position (paper jam position) of the copy paper together with the display of the entire copying machine.

FIG. 4 is a block diagram of the control unit of the copying machine. The entire control is performed by the program processing of the CPU 100,
The control program is written in the ROM 101 in advance. The RAM 102 is used as a working area for various buffers and flags when executing the program. The I / O 103 is connected to various input / output devices and inputs / outputs signals in accordance with instructions from the CPU 100. The LED array 105 is a charge eliminating lamp arranged between the charging unit and the developing unit of the photosensitive drum, and removes the electric charge in that region by turning on a predetermined LED at a predetermined timing.

For example, when erasing the hatched portion in FIG.
The LEDs Y1 to Y2 of the ED array are turned on at timings X1 to X2.

The driver 104 is a drive circuit of the LED array 105, and selectively drives the LEDs according to the control signal of the CPU 100. The display body 107 is a display body for displaying various information including the numeral display body shown in FIG.
The driver 106 drives according to the output signal of 00.

The key input device 108 is an input device including a numeric keypad and an input key, and the CPU 100 reads the content of the operated key via the I / O 103. The I / O 109 sends a CP to the controller 110 for controlling the copying process.
Inputs and outputs signals to and from U100.

5 (A), (B), and (C) are flowcharts showing the processing procedure of the control unit.

First, when the power is turned on, as shown in FIG.
The specific area of M is initialized and the key is read (n10 → n12). If the operated key is the range setting mode key, the flag FA representing that mode is set, and four of the 3rd digit day character segments shown in FIG. 2, c, d, e and g, are selected. Turn on (n16 →
n17) (see FIG. 1 (A)). Then, as shown in FIG. 1 (B), both the segments c and e are blinked until the input key is operated to indicate that the left and right edges of the area are to be input (n15 →→ n40 → n42 → n44 →
n46).

Here, ST shown in FIG. 5 (C) is a counter that counts how far the area is input, and is "0" in the initial state. When the ten-key is operated in this state and "11" is input, the entered contents are displayed as shown in FIG. 1 (C). If the input key is operated after that, the registered display is erased, and the registered value is stored in the buffer X.
Input 1 (n28 →→ n60 → n62 → n6
4).

After that, the counter ST is incremented (n66), and the process returns to the key reading routine. At this time, the counter ST is "1"
As a result, the segment e is turned on,
The display is as shown in FIG. 1 (D) (n42 → n4
8). This display state indicates that the right end of the area to be designated is in the state to be input.

For example, if the numeric keypad is operated here and "22" is input, the display shown in FIG. 1 (E) is displayed, and if the input key is further operated, the numerical display is erased and the value is stored in the buffer X2. It is input (n70). After that, since the counter ST is incremented at n66, the segment c is turned on and the segments d and g are turned on and off as shown in FIG.
n52). This display state indicates that the front and rear edges of the area to be designated should be input.

For example, if "33" is entered and the input key is operated, the value is input to the buffer Y1 (n74). Since the counter ST = 3 at this time, the segment d is in the lighting state and the segment g is kept in the blinking state as shown in FIG. 1 (H) when the key operation is not performed. (N54). This display indicates that the other end (rear end) of the front and rear ends should be input.

If, for example, "44" is entered and the input key is operated, the value is input to the buffer Y2, all four segments c, d, e, g are turned on, and the counter ST is reset. (N76 → n78 → n8
0).

With the above procedure, the coordinates of the left and right edges and the front and rear edges of the area can be easily input while visually grasping the four segments c, d, e, and g. In the embodiment, when inputting the coordinates of the left and right ends, the example can be input from either the left end or the right end. It is also possible to input one coordinate sequentially.
