DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in an inter-device communication device. For example, a passbook printer and a slip printer used for an operator terminal in a financial institution are housed in the same housing, and print as a passbook / slip printer device in synchronization with each other in accordance with print data output from the operator terminal. .

In such an apparatus, for example, when a jam occurs in one of the printers and the cover is removed by an operator, the power supply for driving the mechanism is cut off in both printers. If the power supply is common, it is necessary to perform error processing for the respective devices, and to turn off the power supply after confirming completion of the other error processing.

[0003] For this reason, it is necessary to communicate between the processors which are respectively controlling the printers. One device is newly constructed by a combination of developed devices, such as a passbook / slip printer device. In such a case, a separate means for communication must be provided.

[0004] Therefore, there is a demand for an inter-device communication device for easily performing inter-device communication without providing special hardware.

[0005]

2. Description of the Related Art FIG. 5 is a block diagram of a passbook / slip printer device.
FIG. 6 is a configuration diagram of a conventional example. Transactions such as transfers, deposits, and payments received at the counter of the financial institution are processed by the operator terminal. In order to efficiently perform bookkeeping, issuance of slips, and the like of this transaction, a passbook / slip printer system (apparatus) in which the passbook printer and the slip printer are housed in the same housing and operated with the same power supply has been developed. .

FIG. 5 shows one of the passbook / slip printer devices.
This is an example. This passbook / slip printer device 2
Has a built-in slip printer unit and passbook printer unit, and a transaction result is printed by inserting a slip into the slip insertion slot 3 and a passbook into the passbook insertion slot 4, respectively.

Here, the operation panel (operator panel) 5
Has a display unit 6 such as a liquid crystal display of two rows and 16 digits, one upper line as a slip display unit 6a, one lower line as a passbook display unit 6b, and displays the printing progress status of each printer unit. , Error display etc. are performed.

Here, for example, when the occurrence of a jam is displayed on the passbook display section 6a, the operator removes the cover 31 and performs processing such as taking out the passbook. In this processing, a slip is printed. And the failure is easy to occur.

Therefore, in response to the notification from the limit switch 30 for detecting the detachment of the cover, both the devices perform a predetermined error process such as a process of saving data and a process of ending the reception of a command from the operator terminal 1, and then perform a power-on operation. Although disconnection control is performed, it is necessary to confirm each other whether or not error processing has been completed before issuing a power-off command, that is, to synchronize.

The same applies to the case where processing such as turning off the power supply is performed due to a failure peculiar to each printer, and it is necessary to check the progress of the processing of the partner apparatus by communication between apparatuses. FIG. 6 shows an example of inter-device communication by well-known inter-processor communication using a common memory.

In the slip printer unit 10 shown in FIG. 6, when there is an interrupt from the limit switch 30 (cover has been removed), the microprocessor MPU 12 performs the above-described error processing, and then stores the power-off notification data in the common memory 16. And waits for a response from the passbook printer 20 (writing of an acknowledgment code to the common memory 16). Then, after it is confirmed that the acknowledgment code has been written, the power-off command is sent to the power supply 41 via the OR gate 40. Thus, the power supply 41 cuts off the power supply to the printer mechanism 15 and the printer mechanism 25.

On the other hand, the passbook printer unit 20 also performs the above-described error processing by the interruption from the limit switch 30, and notifies the power supply 41 of a power-off command by a response from the slip printer unit 10.

At this time, the power-off notification data is written to each other. If the other party has already written the power-off notification data to the common memory 16 at the time of this writing, the other party also issues a power-off command assuming that error processing has been completed. After confirming that the error processing of the own device has been completed, the response data to the power-off notification data of the other device is written. As a result, after confirming the completion of the error processing on the other side, a power-off command is notified from both devices to the power supply 41.

[0014]

As described above,
The communication between the processors by the common memory 16 synchronizes the slip printer and the passbook printer, and the power supply 41 can be turned off, but as a slip printer and a passbook printer,
If you use ones developed independently, you need to add additional hardware for the common memory 16,
There is a problem that the device becomes expensive.

The present invention has been made in consideration of the above problems, and has as its object to provide an inter-device communication device that can easily perform inter-device communication.

[0016]

In order to achieve the above-mentioned object, an inter-device communication device according to the present invention comprises a display unit 53 in which a display area is allocated to each device as shown in the principle diagram of the present invention in FIG. A display memory 54 in which display data is stored corresponding to the display area, and first and second plurality of devices each storing display data in its own area allocated to the display memory 54. Transmitting means 55 provided in the first device 51 for storing transmission data in its own memory area in the display memory;
Receiving means 56 for reading the memory area of the first device in the display memory and receiving the transmission data, the display memory shared between the devices.
It is configured to perform communication between the first device 51 and the second device 52 via 54.

[0017]

[Operation] For example, like a display section of an operator panel,
Communication between the devices is performed using the display memory 54 of the display unit 53 in which the display area is allocated for each device.

In the first device 51 on the transmitting side, the transmitting means 55 stores transmission data in its own memory area in the display memory 54, and in the second device 52 on the receiving side, the receiving means 56 1
The device 51 reads the contents of the memory area of the device 51 and receives the transmission data.

As described above, by using the shared display memory used for the operator panel and the like, communication between the devices can be easily realized. By providing both the transmitting means 55 and the receiving means 56 in each device, mutual communication can be performed.

Reference numeral 8 denotes a display memory, an area A for storing character codes displayed on the slip display section 6a, and a passbook display section 6b.
Are stored in an area B in which the character code displayed in the area B is stored. The area A is writable only from the slip printer unit 10, and the area B is writable only from the passbook printer unit 20. It should be noted that reading is possible from both printer units.

Reference numeral 9 denotes a memory control unit which is connected to both the bus 100 (consisting of control lines, address lines, and data lines) of the slip printer unit 10 and the bus 101 of the passbook printer unit 20, and Alternatively, the display memory 8 is controlled by access from the passbook printer unit 20.

In the slip printer unit 10, an operation panel control unit 11 accesses the display memory 8 of the operation panel 5 based on an instruction from the MPU 12 or the like. In addition, conventionally, only the writing operation of the area A was performed, but in the present invention, the reading of the area B is also performed. The timing is, for example, as described later,
Performed when writing to area A.

Reference numeral 12 denotes a microprocessor MPU which controls each unit in the slip printer unit 10 to perform printing control, and activates an abnormality processing unit 18 by interruption from a limit switch 30 or the like. Reference numeral 18 denotes an abnormality control unit, which is a power-off notification data (transmission data) when activated by the MPU 12.
When the response data from the passbook printer unit 20 is received via the operation panel control unit 11, a power-off command is output to the power supply 41 to the OR gate 40.

When the passbook printer unit 20 reads the power-off notification data written in the display memory 8 due to a timer interrupt or the like, the power-off command is output to the power source 41 after performing a predetermined error process. The control unit 11 requests the operation panel control unit 11 to write the response data into the display memory 8.

Reference numeral 13 denotes a memory for storing print data received through the interface unit 17. A printer control unit 14 controls the printing of the received print data while controlling the printer mechanism 15. Reference numeral 15 denotes a printer mechanism having a slip sending mechanism, a print head, and the like. Note that the power supply of the printer mechanism 15, for example, a pin drive power supply is a power-off target.

The interface unit 17 is an interface with the operator terminal. Although the interface unit 17 is provided in the slip printer unit 10 here, it is shared with the passbook printer unit 20. That is,
One of the printer units occupies the interface unit 17 and communicates with the operator terminal. Note that the passbook printer unit 20 may be provided with an interface unit, and may be switched to the interface unit 17.

In the passbook printer unit 20, the operation panel control unit 21, the MPU 22, the abnormality processing unit 28, the memory 23, the printer control unit 24, and the printer mechanism 25 are each a slip printer unit 10
Operation panel control unit 21, MPU 22, error processing unit 28, memory

Reference numeral 30 denotes a limit switch for detecting opening / closing of the cover 31 (FIG. 5). When the cover 31 comes off, an interrupt is generated in the slip printer unit 10 and the passbook printer unit 20.
The operation of the above slip / passbook printer when the limit switch 30 is operated will be described below. Referring to FIG. 3, the abnormality processing unit 18 started by the MPU 12 in response to an interrupt from the limit switch 30 performs a command reception termination process, and requests the operation panel control unit 11 to write power-off notification data. The operation panel control unit 11 transmits the power-off notification data (code) to its own line in the display memory 8 of the operation panel 5,
That is, while writing to the area A of the display memory 8, the line used by the other device in the display memory 8 of the operation panel 5,
That is, the area B is read, and the read contents are notified to the abnormality processing unit 18. If the read data is the acknowledgment code, the abnormality processing unit 18 outputs a power-off command.

If the read data is power-off notification data, the power-off command is sent to the operation panel control unit 11 to write an acknowledgment code. If the read data is content other than the predetermined content, here the power-off notification data, the process waits until an acknowledgment code or power-off notification data is written. That is, reading is performed after a certain time has elapsed.

The above processing is similarly performed in the passbook printer unit 20, and a power-off command is sent to the power supply 41 in parallel. In the above operation, since the interrupt is raised to both devices at the same time, the area of the other device can be read at that timing.For example, the slip printer unit 10 may write the notification code unilaterally, In order for the passbook printer unit 20 to read the notification code, the following operation is performed. Referring to FIG. 4, the MPU 22 requests the operation panel control unit 21 to read the area A in the display memory 8 of the operation panel 5 at regular time intervals. Alternatively, at the time of a status display request from the MPU 22, the used line (A area) of another device of the display memory 8 is read, and the read data is returned to the MPU 22. If the read data is power-off notification data (other specific notification data), the MPU 22
After the command reception ending process is performed by 28, the operation panel control unit 21 is requested to write an acknowledgment command.

As a result, the operation panel control unit 21 writes the acknowledgment code in its own line and the B area. Power-off notification data (specific notification data)
If not, the process ends.

The above processing is performed at regular time intervals and / or when the status is displayed. As described above, communication between apparatuses can be performed even when there is no simultaneous interruption for both.

As described above, the inter-processor communication for controlling each device can be performed using the display memory 8 provided in the common operation panel 5, and it is necessary to add hardware such as a common memory. Absent.
