Abstract

PURPOSE:To restrict an unnecessary copying by providing a card inserting mechanism, a reading circuit, a lock means, a signal generating means, a password number input key and a password number check function. CONSTITUTION:When a card I incorporating an IC is inserted and the number of copies is set to a counter 11 and a password number is inputted and a switch 10is operated, copies whose number is equal to the number set to the counter 11 are obtained if the contents of the card 1 are not zero. If the contents of the card 1 are zero even when the card 1 is inserted and the number of copies is set to the counter 11 and the switch 10 is operated, copying is not performed because output '1' is outputted from an AND gate 16. Though copying is started when the contents of the card 1 are not zero, copying is stopped when the contents of the card 1 become zero. Thus, the unnecessary copying is restricted.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a copying apparatus.

Copying devices have become widespread in recent years and are often used in businesses.

However, if the copying machine is used as desired, it will cost a lot of money.

[Conventional technology]

Therefore, in companies, counters are provided for each department or section so that the number of copies for each department or section can be managed.

[Problem that the invention seeks to solve]

However, conventionally used counters count the number of copies in an additive manner, and do not indicate how many copies can be made.

This method simply adds up the number of copies, which is not desirable in terms of restricting unnecessary copying.

[Means for solving problems]

This invention was made from this point of view, and the number of copies assigned to each counter is set in advance, and copies can be made within the assigned number, but if the contents of the counter become zero. For example, copying is not possible even if the copy switch is operated.

[Effect]

When the actual number of copies is subtracted from the number of copies set on the IC card and becomes zero, the copy switch is locked to prevent further copies.

〔Example〕

Figure 1 shows an IC built-in card (1) that is a feature of this invention.
The card (1) has an IC chip (2) that constitutes a microcomputer and memory (for example, EEpFLoM: electrically erasable FROM) embedded in a plastic plate, and the chip (2) is It is connected to input/output terminals (31) arranged in parallel on one side of the plastic plate, and is designed to exchange signals with the outside.

The counting function circuit therein is configured to subtract the number of copies each time from the initially set number of copies that can be made. In other words, it functions as a subtraction type counter. That is, the set number of copies is different for each department, and this number of copies is subtracted each time copying is performed. In addition to the counting function circuit, it has a memory section M that stores the number of copies for each copy size.

FIG. 2 shows a copying section (t[T41) according to the present invention, (5) is a card insertion section, (6) is a reading circuit for reading the contents of the card, and unless the contents of the card are zero, the copying section If the value is zero, a signal indicating that copying is not possible is issued.

The signal from the copying section is applied to an operating section (7) equipped with a password-type Kaki-K, which is one of the features of the present invention. Note that the password type key is operated with a card inserted, and the password is input.

On the other hand, a signal indicating that copying is not allowed is also given to the operating section (7).

(8) is a copying unit equipped with a function O for checking the password entered using the key K, and the operating unit ( 7) The set number of copies is made by operating the various switches constituting the unit. (9) is a signal generator that generates a subtraction pulse and a signal for each copy size;
Outputs one pulse per 41 sheets and inserts it into the insertion section (5)
K is applied to the counting function circuit of the inserted card.

The counting function circuit that receives this pulse performs a subtraction operation and subtracts from the initially set number of copies that can be made.

Also, from the signal generator (9), A49 person 3. A signal indicating the number of copies for each copy size, such as λ5, is generated and applied to the memory section M of the IC+21, which serves as a trap so that it can be determined how many copies of which size have been made.

FIG. 3 shows the operation circuit section which is the gist of this invention, where aO is a copy switch, (lυ is for setting the number of copies,
A subtraction counter (I3 is a flip-flop, S indicates a set side, R indicates a reset side) which performs a subtraction operation by a subtraction pulse α2 generated from a signal generator (9).

I is a signal line, and if the content of the card (11) is not zero, a logical "1n" signal passes through it, and if it is $, it becomes a logical "0".0!9 is an inverter. When the content of the counter U is zero, an output of "1" is given to the reset input terminal of the flip-flop C13.

On the other hand, if the contents of the counter are other than zero, the output is “0”
It is. αe is a three-person AND gate.

In the case of "1n", all three output a logical "1" signal, which is supplied to the copying section (8)K.

On the other hand, if the content of either card (1) or counter αD is zero, the AND game) (The output of IG is “
0'' and is not a copy condition.

It should be noted that the copying section (8) is configured to check the PIN number entered in the PIN type key using the PIN code checking function 0 provided therein.

Even if the output of the AND gate ae is "1", the device will not operate if the entered password is incorrect.

Further, the signal given to the card (11) is indicated by the symbol c!

In such a configuration, insert the card (1).

If you set the number of copies to the counter αυ, enter the PIN number, and then operate the switch aG, the number of copies will be copied to the counter (111) unless the contents of the card (1) are zero.On the other hand, if the contents of the card (1) Even if the card +11 is inserted, the counter a11 is set, and the switch αυ is inserted, if the contents of the card +11 are zero, no output of "1" is output from the game) fie, so no copying is performed. Furthermore, even if copying is started when the contents of card (1) are not zero, card (11)
When the content of becomes zero, copying stops. By the way, in the above description, copying is possible until the contents of card (1) become zero. Although a so-called subtraction type is given as an example, it may also be an addition type.

That is, the counting function circuit of the card (1) can be used as a preset counter, and copies can be made until the total number of copies reaches a preset value (the preset value is the number of copies that can be made).

In this case, the pulses originating from the signal generator (9) are treated as addition pulses.

In another embodiment of the present invention, FIG. 4 (4) shows a case where the number of copies is outputted by voice from the voice synthesis output means a71. For example, when the number of copies that can be made falls below a predetermined number, a predetermined output is output from the voice synthesis circuit (18) connected to the card, and the output is output as sound by the speaker f19.

On the other hand, in Figure 4 (Tomari), the remaining number of copies that can be made is 0 IC0.
The second element is a flicker means (2) for blinking the lamp, which causes the lamp @ to blink with the output of the flicker signal generating circuit C+11. In this way, if the number of copies is indicated by sound or flicker, the user will be careful when copying.

The display in FIG. 3 is for continuously or timely displaying the contents of the counting function circuit on the card (11), and the contents of the counting function circuit can be easily recognized by looking at this display.

〔Effect of the invention〕

Since the present invention is configured as described above, the copying apparatus can be effectively utilized. The gist of the present invention is not to limit necessary copying, but to limit unnecessary copying.
