[Detailed Description of the Invention] [Summary] The purpose of this invention is to provide a printing device for PO8 that prevents irregular printing and improves reliability with respect to a printing device used in a PO8 device, and detects vibration or impact. a storage means for storing the received print data; a timer means for monitoring for a predetermined period of time when vibration or impact is detected by the detection means; and control means for controlling the print data to be read out from the storage means and printed when there is no re-detection after a predetermined period of time.

[Industrial application field] The present invention relates to a printing device used in a PO8 device.

In recent years, PO8 printers used in PO3 (point of sales) devices have become lighter and simpler.
In addition, it is connected to the control section with a cable, etc., and installed as a module. This PO8 printer may be subject to shocks due to vibrations on the installation table or handling by the operator, and if it is subjected to vibrations or shocks while printing,
This will result in irregular printing.

Therefore, it is necessary to detect vibrations and impacts to prevent irregular printing.

[Prior art] In conventional PO8 devices, the customer enters information on the purchased products and the amount from the keyboard section, displays the information on the display, and sends print data from the control section to the printer, where the print data is sent to the printer. After printing, a response was sent to the control unit indicating the completion of the process, and then one sheet was issued to the customer (see Figure 4).

In this case, even if the printer prints irregularly due to vibrations of the installation table or shocks caused by handling by the operator, the control section cannot recognize the irregular printing, so the receipt is issued to the customer with irregular printing, and the journal I was winding it up.

[Problem to be Solved by the Invention 1] With such conventional PO8 devices, product information and amounts become unclear due to irregular printing, so the operation 1 nosion that has been totaled has to be restarted from the beginning, and the customer There were problems in that it caused a lot of trouble and reduced reliability.

The present invention has been made in view of these conventional problems, and an object of the present invention is to provide a PO8 printing device that prevents irregular printing (7) and improves reliability. .

[Means to solve the problem] FIG. 1 is a diagram explaining the principle of the present invention.

In FIG. 1, 9 is a detection means for detecting vibration or impact, 10 is a storage means for storing received print data, and 14 is a timer for monitoring for a predetermined time when vibration or impact is detected by the detection means 9. Means 15 is a control means that stops printing when vibration or shock is detected during printing, and when no re-detection occurs after a predetermined period of time, controls the printing data to be read out from the storage means 10 and printed.

[Function] In the present invention, when vibration or impact is detected by the detection means, the timer means monitors for a predetermined time,
If no vibration or impact is detected thereafter, printing is performed. Further, if vibration or impact is detected again during printing, printing is stopped, and if vibration or impact is not detected after a predetermined time, printing data is read from the storage means and printing is performed.

Therefore, the occurrence of irregular printing due to vibration or shock can be prevented, and the product information and amount on the receipt will not become unclear, so customers will not be inconvenienced. As a result, the reliability of the device can be improved.

[Example] Embodiments of the present invention will be described below based on the drawings.

FIGS. 2 and 3 are diagrams showing one embodiment of the present invention.

First, to explain the configuration, in Fig. 2, 1- is a PO8 device installed on a table (not shown);
A printer 2 is provided in the device 1, and a printer 2 is provided in the device 1. - A roll part 3 is provided.

Reference numeral 4 denotes an input unit connected to the control unit 3 and a keyboard 17, through which the customer's purchased product information, price, etc. are inputted through the keyboard 4 through the operation of the operator 1 notator.

Reference numeral 5 denotes a display as a display section, and the input amount and the like are displayed on the display 5 under the control of the control section 3. Further, 6 is a drawer device, and the drawer device 6 is designed to store sales proceeds.

The printer 2 includes a printing section 7 as a mechanical section that performs printing, a printing control section 8 that controls the printing section 7, and a sensor (detection means) 9 that detects shocks caused by vibrations of the table or handling by an operator. are doing. Reference numeral 10 denotes a memory as a storage means, and the memory 10 stores print data input from the control I/roll section 3 via a cable 11 through a buffer 12. Furthermore, a control program for controlling irregular printing is stored in the ROM 13.

A timer 14 serves as a timer means, and the timer 14 monitors for a predetermined period of time when the sensor 9 detects vibration or impact before or during printing. 15 is a CPU as a control means, and when the sensor 9 detects vibration or shock during printing, the CPU 15 stops printing;
When no vibration or impact is detected again after a predetermined period of time, the printing data is read from the memory 9 and the printing unit 7 is controlled to perform printing.

Next, the effect will be explained.

FIG. 3 shows a control program for controlling irregular printing.

In FIG. 3, first, in step S1, the control section 3
The print data is received from the printer via the buffer 12, and the received print data is stored in the memory 10. Next, in step S2, it is determined whether the sensor 9 is detecting vibration or impact. When vibration or impact is detected, the timer 14 is activated in step S3 to monitor for a predetermined period of time, and the process returns to step S1. When the sensor 9 does not detect vibration or impact, the print section 7 prints print data in step S4. If the sensor 9 re-detects vibration or impact in step S5 during this printing, step S
Printing is stopped at step S6, and the timer 14 is activated at step S7 to monitor for a predetermined period of time.

If the sensor 9 is still detecting vibration or impact again in step S8 after a predetermined period of time, the process returns to step S7, and if the sensor 9 has not detected vibration or impact again, the process proceeds to step S9. In step S9, the print data is read out again from the memory 10, and in step 810, overlapping printing is performed. If the sensor 9 does not detect vibration or impact again in step S5, a processing end response signal is sent to the control unit in step S1l.

In this way, it is possible to detect vibrations or shocks and prevent the occurrence of irregular printing, so that the product information or amount on the receipt will not become unclear, and the customer will not be inconvenienced. As a result, the reliability of the device can be improved.

[Effects of the Invention] As explained above, according to the present invention, when vibration or impact is detected, monitoring is performed for a predetermined period of time, and when vibration or impact is no longer detected, printing is performed, and When there is vibration or shock, printing is stopped, and if no re-detection occurs after a predetermined period of time, printing is continued, thereby preventing irregular printing.

As a result, the reliability of the device can be improved without causing any inconvenience to the customer.
