When the gate of the buffer circuit 36 is opened by the pulse signal of, the potential of the drawer switch side output terminal of the buffer circuit 36 is +5 V when the drawer switch 23 is OFF,
When it is ON, it becomes 0V.

Next, the operation of the electronic cash register according to this embodiment during a transaction will be described with reference to the flowchart of FIG. When the start of the sales registration process is instructed, switch sense is performed in step S1 and the drawer 4
Also, it will be determined whether or not the bill inspection plate 8 is in an error state, the details of which will be described later.
Here, a case will be described in which the drawer 4 is in the stored state and the inspection panel 8 is in the closed state, and is not in the error state. If there is no error, the process proceeds to the next step S2.

In step S2, the data related to the merchandise registration input from the keyboard 26 is accepted, and in step S2
By checking whether or not the subtotal key is pressed in 3, it is determined whether or not the product registration operation is completed. When the subtotal key is pressed, the total amount of sales is calculated and the total amount is displayed on the display 33.

The operator requests the customer to pay based on the amount displayed on the display 33, enters the deposit amount paid by the customer using the keyboard 26, and subsequently indicates that the deposited amount is the deposit amount. Because of current /
Press the deposit key or coin change key. Then, step S4
The amount of money input from the keyboard 26 at RAM2
5 into the work buffer 25d, and then step 5
In step S6, it is determined whether or not the coin key is pressed.
In step S7, when it is detected that the cash / deposit key is pressed, if the cash / deposit key is pressed, the data indicating that the previous amount is the deposit amount is stored.

Next, in step S8, it is determined whether or not the deposit amount is less than 1000 yen, and in step S9, the total amount of sales and the deposit amount are compared to determine the presence or absence of change, and in step S8, the deposit amount is set. When it is determined that the amount of money is not less than 1000 yen, and when it is determined that there is change in step S9, the process proceeds to step S10 and the drawer 4 of the drawer 2 is pulled out and opened by an automatic opening device (not shown). ,
By shifting to step S11 and energizing the solenoid 18, the shutter plate 16 is slid against the tension spring 17 and its openings 16a to 16f are moved from positions facing the coin insertion openings 6a to 6f as shown in FIG. By shifting the coin input ports 6a to 6f, the shutter plate 1
Block with 6.

In such a state, as shown in FIG. 1, by opening the drawer 4, the deposits can be stored in the coin storing units 5a to 5f or the bill storing units 5g to 5j according to their denominations. The change can be taken out from each storage unit and handed to the customer, and furthermore, the surface of the bill inspection plates 7 and 8 can be effectively used when the deposit is changed, which is preferable in terms of workability. can get. or,
In this state, the coin insertion ports 6a to 6f are connected to the shutter plate 1.
Since it is closed by 6, coins are inserted into the coin insertion openings 6a to 6f at the place where the coin inspection plate 8 is left open.
Therefore, it does not fall into the drawer 4 by mistake, and therefore there is no problem of being stored in the wrong storage portion in the drawer 4.

On the other hand, if it is determined in step S8 that the deposit amount is less than 1000 yen and it is determined that there is no change in step S9, step S9
14, the solenoid 12 is energized and the lock claw 14
And the engagement with the engagement claw 8d are released. Then, the coin inspection plate 8 is opened by the biasing force of the torsion spring 9 as the lock is released, and is held rearward, that is, in a state of being inclined downward toward the coin insertion ports 6a to 6f, as shown in FIG. Therefore, if the coin 38 is inserted into the coin guide paths 10a to 10f on the back surface of the coin inspection plate 8 according to its denomination, the coin 38 slides down along the coin guide paths 10a to 10f, and the coin slot 6 is inserted.
It can be stored in the drawer 4 from a to 6f, that is, in the corresponding coin storage portions 5a to 5f.

In this way, when the deposit is only coins, it is possible to open the drawer 4 of the drawer 2 one by one without opening the coin inspection plate 8.
Can be effectively used to be stored in the predetermined coin storage portions 5a to 5f. Therefore, not only can the money storage operation be simplified, but also the money can be prevented from being lost by opening the drawer 4 unnecessarily.

The reason why the cash / deposit key and the coin change key are provided separately as keys to be pressed to indicate that the amount of money entered in step S4 is the amount of money to be deposited is 1000 yen or more. This is because even in the case of, there is a case where the coin is paid only and there is no change, and in such a case, the operator presses the change key.

That is, when the depression of the coin key is detected in step S5, the data indicating that the previous amount is the deposit amount is stored in step S12, and the process proceeds to step S13 where the total amount of sales and the deposit amount. The change is compared to determine whether there is change, and if there is change, the process proceeds to step S10, and the drawer 4 of the drawer 2 is opened by the same operation as above. On the other hand, when it is determined that there is no change, the process proceeds to step S14, and the solenoid 12 is energized to open the coin inspection plate 8 as before. Therefore, the coin guide paths 10a to 1 on the back surface of the coin inspection plate 8
The coin 38 can be stored in the corresponding coin storage portions 5a to 5f via the coin insertion ports 6a to 6f by using 0f.

Therefore, in the present embodiment, when the deposit is only coins and no change is required, it is not necessary to open the drawer 4 of the drawer 2 one by one, and the coins 6a to 6f of the drawer main body 3 can be used. Since coins can be inserted and stored in the coin storage portions 5a to 5f in the drawer 4, the workability of storing coins, particularly coins, can be improved, while there is a concern that the coins will be lost due to the unnecessary opening of the drawer 4. There will be nothing. Further, since the coin insertion ports 6a to 6f are normally placed in a closed state by the coin inspection plate 8, there is no problem that small equipment or scraps of receipts accidentally enter the drawer 4, and the coin inspection plates 7 and 8 are not provided. It can be effectively used when, for example, changing the deposit on the surface of the.

Furthermore, if the coin change key indicating that the deposit is only coins is pressed, the coin inspection plate 8 is automatically opened after confirming that there is no change, so that the independent coin inspection plate 8 is opened. Is unnecessary, the operability is improved, and furthermore, when the drawer 4 is opened, the coin inlets 6a to 6f are forcibly closed by the shutter plate 16, so that the coin inspection plate 8 should be used.
Coin insertion slot 6a-
The problem that coins fall into the drawer 4 from 6f does not occur.

Next, error detection (switch sense in the previous step S1) in the electronic cash register according to this embodiment will be described with reference to the flowchart shown in FIG. First, in step S21, the CPU 35 executes the switch sense command, inputs the LOW pulse signal as the SW sense signal to the buffer circuit 36, and changes the state of the drawer switch 23 by the signal appearing at the drawer switch side output terminal of the buffer circuit 36. Detected (step S2
2) Then, the state of the money inspection board switch 20 is detected by the signal appearing at the output terminal of the money inspection board switch (step S).
23).

In step S22, the buffer circuit 3
It is determined whether the signal appearing at the output terminal of the drawer switch 6 is LOW, and if it is LOW, the drawer switch 2
It is determined that the drawer 3 is in the ON state and the drawer 4 is not normally stored, and if the drawer is HIGH, it is determined that the drawer switch 23 is in the OFF state and the drawer is normally stored. In step S23, the buffer circuit 3
The signal appearing on the output terminal of the 6th inspection plate switch side is HIGH
If it is HIGH, it is determined that the money inspection plate switch 20 is in the ON state and the money inspection plate 8 is normally closed, and if it is LOW, the money inspection plate switch 20 is determined. It is determined that the coin inspection plate 8 is not normally closed due to the OFF state. When a HIGH signal appears at the drawer switch side output terminal and the coin inspection board switch side output terminal of the buffer circuit 36, the drawer 4 is normally stored and the coin inspection board 8 is normally closed. , The previous step S2
Move to

When it is determined in step S22 that the drawer 4 is not normally stored, step S22
After shifting to 24, a flag "1" for indicating a drawer open error is set in the SW flag portion 25c, and a buzzer 34 is sounded in a succeeding step S25 to issue a drawer open warning, and further in a step S26, the display 33 is displayed. For example, by displaying the drawer open error display as shown in FIG. 18A, the operator is prompted to store the drawer 4 normally.

Then, in step S27, the timer counter 25d starts counting down of a predetermined numerical value, and in step S28, it is checked whether or not the CL key is pressed, and in step S30, the numerical value of the timer counter 25d is set to 0. At this time, see if it became
When the pressing of the CL key is detected in step S28,
The drawer open warning issued earlier is stopped in step S29, and the timer counter 2 is activated in step S30.
When it is detected that the value of 5d becomes 0, step S
The switch sense command is executed at 31 and then it is checked at step S32 whether the flag "1" for indicating the drawer open error is set in the SW flag section 25c.

At this time, an error operation is started when it is detected in step S22 that the drawer 4 is not normally housed, and the SW is started in step S24.
Since the flag "1" indicating the drawer open error is set in the flag section 25c, the flag "1" is detected in step S32 and the process proceeds to step S33, where the output terminal of the buffer circuit 36 on the drawer switch side is output. It is determined whether or not the signal that appears is LOW. When it is LOW, it is determined that the drawer switch 23 is in the ON state and the drawer 4 is not normally stored. When it is HIGH, the drawer switch 23 is in the OFF state. Therefore, it is determined that the drawer is normally stored.

When the error operation is started by detecting that the coin inspection board is not normally closed in step S23, the SW flag portion 25c indicates the coin inspection board open error by the operation control described later. Since the flag "2" is set, the flag "1" is not detected in step S32,
At this time, the process proceeds to step S34 and the buffer circuit 36
It is determined whether or not the signal appearing at the output terminal of the money inspection plate switch is HIGH, and when it is HIGH, it is determined that the money inspection plate switch 20 is in the ON state and the money inspection plate 8 is normally closed. However, in the case of LOW, the money inspection plate switch 20 is O
It is determined that the coin inspection plate 8 is not normally closed in the FF state.

Then, as a result of the respective determinations, when it is determined in step S33 that the drawer 4 is not normally stored, or in step S34, the check panel 8 is inserted.
