DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a copying apparatus such as an electrophotographic copying apparatus in which a copying operation is dispersed.

[Background of the invention]

2. Description of the Related Art In recent years, copying machines have become widely popular as their performance and functions have improved and their prices have fallen, and their usage rate has become extremely high. However, as devices become more multi-functional and a variety of functions become possible, the number of operation buttons increases, and on the other hand, a problem arises in that operability becomes complicated. Therefore, as the usage rate increases, there is a demand for a device that is easy to operate.

[Purpose of the invention]

Conventional copying apparatuses are inconvenient because it is necessary to press a copy button to start copying each time a document is set on a document table and a copy is made.

The present invention provides a copy mode in which a copy operation starts when a document is placed on the document table and the document cover is closed, thereby eliminating the need to press the copy button each time a document is replaced. The purpose is to provide a copying device.

[Structure of the invention]

An object of the present invention is to provide a copy mode in which either a first copy mode in which copying is performed by pressing a copy button and a second copy mode in which copying is performed in connection with closing a document cover is selected. A selection switch is provided, and when the second copy mode is selected by the copy mode selection switch and the document cover is closed without setting the number of copies, copying is continued until this is detected and the copy stop button is pressed. This is achieved by a copying apparatus characterized in that it is set to continue.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view showing an example of the keyboard section of the copying apparatus of the present invention, FIGS. FIG. 3 is a block diagram showing the control system of the present invention.

In the figure, ■ is a copying apparatus of the present invention, 2 is a document cover 3 that covers the placed document and is fixed on the document table, is a keyboard of the operation section of the copying device 1, and 4 is a detecting state when the document cover 2 is closed. For example, a cover closing detection sensor (hereinafter also referred to as a detection sensor) consisting of a light emitting element and a light receiving element, 4a a detection unit that detects the closing of the document cover 2, 5 a glass plate serving as a document mounting table, and 11 a copying device. 12 is the image copying part of the copying apparatus 1, 20 is a control unit in the main body of the apparatus that controls the image forming process, 31 is a copy button on the keyboard 3 that issues a copy start command signal, 32 is the keyboard a display section for displaying the number of copies provided at 3;
3 is a numeric keypad for inputting the number of copies, etc.; 34 is a copy mode selection switch (hereinafter also referred to as a selection switch), which is made of, for example, a slide switch, for switching the copy mode; 35 is provided near the numeric keypad 33 of the keyboard 3, and when pressed This is a clear key (stop button) that cancels the input number and stops the copy operation. Note that a micro switch or the like may be used as the cover closure detection sensor 4.

When a main switch (not shown) of the copying apparatus 1 is turned on, a warming-up process such as preliminary heating of the fixing device is performed under the control of the control unit IO, and the apparatus waits for a copying operation. Prior to copying, a copy mode is selected using the selection switch 34.

Here, in the first mode, the number of copies is input into the control unit 10 using the numeric keypad 33, and the original is placed at a predetermined position on the glass plate 5, which is the original placing table, as in conventional normal copying, and the original is placed on the original cover 2. This is a copy mode in which the copy button 31 is closed and the set number of copies are made by pressing the copy button 31.

In the second mode, when the document is correctly set on the glass plate 5 and the document cover 2 is closed, if the number of copies is set in advance, the set number of copies are made and the copying operation is stopped (copy stop knob).

If the number of copies is not set, if the number of copies is not set,
This is a copy mode in which the copying operation proceeds when the button is closed and the copying operation is stopped by pressing the stop button 35 (clear key).

Next, we will explain the operation procedure and operation of the above copy mode in the fourth section.
This will be explained with reference to the 70-chart in FIG.

It is assumed that the copying apparatus 11 is already in a start state in which the main switch has been turned on, the warming amplifier has finished, and it is in a copy operation standby state. The numbers within 0 below are step numbers.

First mode: Slide the selection switch 34 of the keyboard 3 upward to select the first mode. Then, (1) the control unit 10 determines whether the selected mode is the first mode;
The control unit 10 controls the image copying section 12 to advance the copying operation in the order of steps (2) to (8).

(2) Input the number of copies into the control unit 10 using the numeric keypad 33. The control unit 10 displays the set number of sheets on the display unit 32.

(3) Next, set the original in the correct position on the glass plate 5, and (4) close the original cover 2. If the lid is not closed, the detection sensor 4 does not send a closing signal to the control unit 20, so the process does not proceed to the next step. [(4) can be omitted in consideration of books etc. (5) When the copy button 31 is pressed, a copy start command signal is sent to the control unit 10, and (6) the control unit 10 controls the image copy portion 12 to proceed with the copying operation.

(7) The copying operation is repeated while the number of copies is smaller than the set number, and when the set number is reached, (8) the control unit 10
stops the copying operation of the image copy portion 12, returns to the start state, and waits for the next copy.

Second mode: Slide the selection switch 34 downward in FIG. 3 to select the second mode. As in the first mode, the control unit 10
controls the image copying section 12 to advance the copying operation as follows.

(1) The selected mode is determined to be the second mode, and the copy operation proceeds in the order of steps (9) to (17).

(9) Input/set the number of copies into the control section 10 using the numeric keypad 33. The control unit 10 displays the set number of sheets on the display unit 32. However, if you enter 0, this corresponds to the case where the number of sheets is not set.

(10) Set the original in the correct position on the glass plate 5.

(11) As in the first mode, the closing lid of the document cover 2 is checked, and only after the document cover 2 is closed is the step (
Proceed to 12).

(12) Here, whether or not the number of copies has been set is checked, and if the number of copies has been set, step (13)
).

(13) Copy operation is performed, (14) Copy operation is repeated while the number of copies is smaller than the set number, and when it becomes equal to the set number, step (1)
(17) A copy stop operation is performed, and the process returns to the starting state.

If the number of copies is set to 0,
The process advances from step (11) to step (15), (15) a copy operation is performed, (16) the copy operation is continued until a copy stop signal is issued by pressing the clear key 35 (stop button), and the copy operation is continued until a copy stop signal is issued by pressing the clear key 35 (stop button). When the button is pressed, (17) a copy stop operation is performed, the process returns to the start state, and waits for the next copy.

Note that at point A between step (11) and step (12), the presence or absence of a document may be detected, and if it is determined that there is no document, a warning may be issued without starting the copying operation. Detection of the presence or absence of a document can be performed using a known technique such as a document size detection means.

Further, in the copying apparatus l of the present invention, since a detection sensor 4 for closing the document cover 2 is provided, the document cover 2 is closed.
Even if the copy button 31 is accidentally touched and pressed before the copy button 31 is closed, the copying operation will not be started. Therefore, the structure can be configured to prevent unnecessary copying before the original is set correctly. .

〔Effect of the invention〕

According to the present invention, with the configuration and operation control described above, in addition to the conventional normal copying operation, it is possible to start the copying operation without pressing the copy button 31, and it is possible to copy a large number of originals. It is possible to provide a copying apparatus that is extremely efficient and labor-saving when making continuous copies.
