Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to copying machines in copying service shops and the like, and particularly to a copying vending machine that minimizes the burden on human hands and is extremely convenient to handle.

Conventionally, in copy service shops, etc., staff members make copies according to customer orders, calculate the number of copies per copy and the unit price according to the copy size, and then charge the customer for the price.

However, copy service shops are often installed in stationery stores, camera shops, etc., and when copying a large number of copies, it may interfere with the original business.

Therefore, in view of the above-mentioned drawbacks, the present invention provides a copying machine with an input slot for inserting money such as coins, and adjusts the input amount based on the unit price of the selected copy size (type such as A4, B4, 5, B5, etc.). Displays the number of copies that can be made.
Each time you copy, the number of displayed sheets decreases, and when the number of sheets reaches "0", the copying is finished, and if there is still a number of sheets that can be copied, if you select another size, the number of sheets that can be copied for the selected size will be reduced. is displayed.

Furthermore, when copying is finished, the change is refunded after calculating the remaining number of copies that can be made and the unit price for the copy size, which reduces the labor burden on copying at copy service shops. This makes handling very convenient for the user.

Hereinafter, the present invention will be explained in detail by giving examples.

The copying machine of the present invention is a general type, and after uniformly charging the surface of a photoreceptor, a light image corresponding to the document is formed on the surface of the photoreceptor to form an electrostatic latent image. After developing with colorant toner, etc., the photoreceptor itself is sent out of the copying machine as a copy, or after development, the toner image is transferred to another transfer paper and the transfer paper is sent out of the copying machine. be.

The main body of the copying machine is provided with a selection switch for selecting copy paper of a copy size according to the original, and the desired copy paper is fed in response to a signal from the selection switch, and the present invention operates in accordance with the signal. The number of copies that can be made is displayed.

In this case, the number of copies that can be made is determined by the amount of money inserted, and means is provided to detect the insertion of coins or the like and totalize the amount of money inserted.

This will be explained below according to the drawings.

The figure is a block diagram showing one embodiment of the present invention.

In the figure, 1 is a coin identification means for detecting coins inserted with 10 yen, 50 yen, or 100 yen, and 2 is an amount signal from the coin identification means and a signal from an amount storage circuit 3 that stores the amount of the input amount until the previous time. This is an adder circuit that performs addition of .

That is, the coin identifying means 1, the addition circuit 2, and the amount storage circuit 3 constitute means for totalizing the amount of money inserted.

Reference numeral 4 denotes a selection switch for selecting the type of copy size. By pressing any of the selection switches 4, copy paper of the corresponding size is fed.

Further, when a coin is inserted, a signal from the coin identifying means 1 is input to the flip-flop 5, the flip-flop 5 is marked, and the signal is added to the AND gate 6.

Therefore, when a coin is inserted, the gate 6 opens and the copy size selection switch 4 selects A4, B4, or B.
A size signal is inputted to the next address register 7 from any one of the address registers 7 and 7.

The address register I reads out the unit price of the corresponding size from the unit price storage means 8 which stores the unit price of each size.

The unit price storage means 8 regularly stores, for example, B size, 10 yen, A4 size 20 yen, and B4 size 30 yen.

Now, if A4 size is selected with the size selection switch 4, 2
A signal indicating a unit price of 0 yen is output.

This signal is applied to the arithmetic control circuit 9.

The arithmetic control circuit 9 receives the content X from the input amount storage circuit 3.
By inputting the content Y from the unit storage circuit 8, X÷
This is a device that calculates Y, and outputs the result of this calculation on the sofa 1.
Output to 0.

The contents of the output buffer 10 are displayed on a display device 12 via a display drive circuit 11.

Therefore, the number displayed on the display device 12 is the number of copies that can be made with the selected copy size for the amount of money that is put in.

On the other hand, if the input content from the size unit price storage circuit 8 is "0", the arithmetic city control circuit 9 sends the signal to the display drive circuit 13, lights up the lamp 14, and confirms that the size unit price is registered. Indicates that there is no

At this time, in order to register the size unit price, first, the registration switch 15 is closed, and an "H" signal is applied to the AND gate 17 via the inverter 16, leaving the gate 17 in an operating state.

In this state, by manually inputting a unit price on the keyboard 18, the unit price is registered and stored in the unit price storage circuit 8 via the key controller 19.

Furthermore, when changing the unit price, etc., the new unit price may be entered using the keyboard 18.

Further, in the figure, reference numeral 20 denotes a second arithmetic control circuit to which the copy count signal C from the copy sensor that is output every time a copy is made is input, and the size that is currently selected is determined based on the contents of the input amount storage circuit 3. Subtract the contents from the unit price storage means corresponding to each time a copy count signal is input,
The result of the subtraction is sent to the input amount storage circuit 3 and the arithmetic control circuit 9.
Therefore, the unit price of the currently selected size is subtracted from the input amount storage circuit 3 every time the copy count signal C is input, and the contents of the subtraction are stored again.

Further, the arithmetic control circuit 9 receives the subtraction details.

Calculate y÷Y between the content
It is displayed on the display device 12 via the display drive circuit 11.

In other words, a countdown is performed on the display section.

21 is a comparison circuit which detects when the content of the calculation result from the calculation control circuit 9 becomes "0" and outputs it to the "LI+ signal AND gate 22" as described above.

A signal F from the copy button is input to the other side of the AND gate 22, and the AND gate 22 outputs a copy start signal S.

Further, the signal D (“L”) from the comparison circuit 21 is inputted to the reset terminal of the flip-flop 5 via the inverter 23.

Therefore, if the signal from the comparison circuit 21 is "L", that is, the calculation signal from the calculation control circuit 9 is "0", the flip-flop 5 is reset, and the selection signal from the size selection switch 4 is input to the address register 7. Therefore, the size unit price storage circuit 8 does not output the signal Y.

Further, reference numeral 24 denotes a fishhook calculator in which the content of the amount currently stored in the amount storage circuit 3 is inputted when the copy end signal is inputted, regardless of the number of copies that can be copied displayed on the display device 12. The circuit calculates the number of 10 yen, 50 yen, 100 yen, etc. according to the contents of the amount storage circuit 3.

This calculation signal is sent to the change selection section 25, and the change selection section 25 returns the change according to the signal.

When the user operates the keyboard 18 to end copying, the key controller 19 outputs a signal E ("H"), and this signal activates the fish hook calculation circuit to calculate change.

The above signal is also applied to the clear circuit 26, thereby clearing the contents of the amount storage circuit 3.

Further, by applying the signal E to the flip-flop circuit 5, the circuit 5 is also reset.

In addition, please do not use the keyboard to finish copying, but instead use display device 1.
Even if all the displayed number of copies of 2 are completed, the content of the amount storage circuit 3 does not necessarily become 0''.

Therefore, when the display on the display device 12 becomes "0", a signal of "L" is outputted from the comparator circuit 21, and this signal is applied to the fishhook calculation circuit 24 via the inverter 27 to perform fishing calculation.

In the configuration described above, let's consider a case where 200 yen is invested to make a copy.

First, when you insert two 100 yen coins into coin identification means 1,
The first 100 yen passes through the addition circuit 2 and the amount storage circuit 3 stores 100 yen.

Then, the next 100 yen and the amount storage circuit 30,100 yen are added in the power calculation circuit 2, and the addition result of 200 yen is stored in the amount storage circuit 3.

By inserting the 100 yen coin, the flip-flop 5 is set, and this cent signal is applied to the AND gate 6.

In this state, if a B4 size copy is to be made, if the size selection switch 4 is operated to select B4, a B4 size signal is input to the address register 7 via the gate 6.

Therefore, from the unit price storage circuit 8, the unit price of B4 size, for example, 3
0 yen is output.

As a result, the arithmetic control circuit 9 calculates X÷Y between the content X of the amount storage circuit 3 and the content Y of the simple storage circuit 8, and the calculation result is "
6" is added to the output buffer 10 and displayed on the display device 12 via the display drive circuit 11.

Therefore, by pressing the copy button, the AND gate 22
A copy start signal S is outputted via the copying point S, and B4 size copy paper is fed.

As a result, when the copying of one B4 size sheet is completed, the copy count signal C is input to the second arithmetic control circuit 20, so the contents of the amount storage circuit 3 and the contents from the unit price storage circuit 8 are subtracted. The subtraction result of 170 yen is stored again in the amount storage circuit 3, and the content of 170 yen is also added to the arithmetic control circuit 9.

Therefore, the arithmetic control circuit 9 executes the division of 170 yen and 30 yen again, and outputs the arithmetic signal to the output buffer 10.

As a result, "5" is displayed on the display device.

As described above, repeat the operation including pressing the copy button, and when the copying of "6" sheets of B4 size is completed, the display device 12 will display "0" and the comparison circuit 21 will output a signal. Output.

Therefore, even if the copy button is pressed in this state, the copy start signal S will not be output.

Furthermore, by outputting the above signal, an activation signal is applied to the fishhook calculation circuit 24 via the inverter 27, so the fishhook calculation circuit 24 takes in the contents (20 yen) of the amount storage circuit 3 and calculates the change. conduct.

Based on this calculation signal, the change selection unit 25 returns 20 yen change.

On the other hand, if the copying of five B4 size sheets is completed in the above-mentioned state and then the A4 size copying is to be performed, the size selection switch 4 is switched to A4 size.

As a result, since the A4 size signal is input to the address register 7, the unit price storage circuit 8 outputs the A4 size unit price, for example, 20 yen.

Then, the content of the amount storage circuit 3 (5
0 yen) and the contents of the unit price storage circuit 8 (20 yen) are calculated, and 2' is displayed on the display device.

By pressing the copy button in this state, an A4 size copy is executed, and when two more A4 size copies are completed, the change selection unit 25 returns 10 yen.

As described above, according to the present invention, the manpower of copy service shops etc. is reduced, and when the copy size is set, the number of copies that can be made is displayed according to the amount of money invested, so the user can copy how many copies. can be easily determined.

However, if you change the size using the copy size selection method, the number of copies that can be made will be displayed according to that size, and even if you make copies of different sizes one after another while copying, the number of copies will be displayed each time. Therefore, the user can omit the trouble of calculating and inputting the amount in advance, which is very convenient.
