Next, referring to FIG. 1, the kitchen printer KP.
The control device 23 will be described. Since the receipt journal printer RJP has the same basic configuration, the kitchen printer KP will be described below. The control device 23 of the kitchen printer KP is composed of a general-purpose microcomputer, and has a CPU (central processing unit) that controls the main control.
A ROM 26 storing software and a RAM 2 storing communication data, operating state, or setting state
7, a switch circuit 2 in which the online switch 11, the offline switch 12, and the feed switch 13 (including the switch of the display / switch panel 19) are connected.
8, a display circuit 29 to which the display 14 (including the switch of the display / switch panel 19) is connected, and a data transmission / reception circuit 31 for transmitting / receiving data to / from the host machine H.
The sensor input circuit 32 and the printer control circuit 33 for controlling the drive of the printer 7 are connected by a bus line.

The sensor input circuit 32 includes a printer 7
Abnormality detection sensor 34 for detecting the abnormality of the cutter
A head-up detection sensor 36 for detecting the print head-up of the printing device 7, a paper-out detection sensor 37 for detecting that the paper 2 has run out, and the lid switch DS are connected. Next, the sales registration device 1 of the present invention having the above configuration
The operations of the kitchen printer KP and the receipt journal printer RJP will be described. Here, it is assumed that the lid panel D is now closed, the paper 2 is set, and there is no other abnormality. In this case, the controller 23 displays the display circuit 29.
Thus, the display 14 indicates that the data from the host machine H can be received, that is, the online state.

As described above, the host machine H transmits the print information data to each kitchen printer KP at the time of order registration, and the receipt journal printer RJP transmits the print information data at the time of settlement.
This data is different for the kitchen printer KP and for the receipt journal printer RJP. That is, since the kitchen printer KP installed in the kitchen only needs to know the food name and quantity to be prepared, the data is, for example, only the ordered product name and quantity, and the kitchen printer KP installed in a waitress filling station called a pantry. In addition, the price of the product and the table No. Data such as is also included. Further, the receipt journal printer RJP data further includes data such as a store name and an address.

Then, the kitchen printer KP selects and receives the data for the kitchen printer KP from the data transmission / reception circuit 31, stores it in the RAM 27, and drives the printing device 7 by the printing device control circuit 33 to place an order. The product name and quantity are printed on paper 2. On the other hand, the receipt journal printer RJP also selects and receives the data for the receipt journal printer RJP from the data transmission / reception circuit 31 and stores it in the RAM 27.
The printing device control circuit 33 drives the printing device 7 to order the product name, quantity, price, and table No. Etc. are printed on the paper 2.

Further, the control device 23 has a sensor input circuit 32.
The cutter abnormality detection sensor 34 and the head-up detection sensor 36 are used to detect the cutter abnormality and the head-up of the printing device 7, and when any abnormality occurs, the data from the host machine H is received. No, that is, the offline state is set, and the occurrence of each abnormality (error) and the offline state are displayed on the display unit 14. When repaired by a service person or the like and the online switch 11 is pressed, the online state is restored again, the error display and the offline display are turned off, and the online display is performed on the display unit 14.

Further, when the printing paper 2 is used up,
The control device 23 detects this by the paper out detection sensor 37. Hereinafter, the operation when the paper is out (paper out) occurs will be described with reference to the flowchart of FIG. The operation of the receipt journal printer RJP is also the same, so the explanation is omitted. If it is assumed that the paper is out in step S1, the control device 23 disables the data reception from the host machine H in step S2, that is, it is set to the offline state, and the parallel signal line of the parallel signal line is transmitted via the data transmission / reception circuit 31. In this case, in the case of a serial communication line, in the case of a serial communication line, a flag or the like is used to notify the host machine H that there is no paper, and in step S3 the online display of the display 14 is turned off, and instead an offline display and the occurrence of paper are displayed. .

The operator notices that the paper 2 of the kitchen printer KP is exhausted by the report to the host machine H and the display of the paper out on the display 14 as described above. Then, when the operator opens the lid panel D to replace the paper 2, the lid switch DS is turned off as described above. The state of the lid switch DS is determined in step S4, and step S4 is repeated while it is OFF. Then, the replacement of the paper 2 is completed, the lid panel D is closed, and O
When the N state is reached, the control device 23 proceeds from step S4 to step S5 to determine whether or not the sheet is normally inserted by the sheet absence detection sensor 37, and if not (N
G) Repeatedly, if inserted (OK), the process goes to step S6 to turn off the no-paper display on the display unit 14.

Next, in step S7, other abnormalities (abnormality of the cutter of the printer 7 and head-up)
If any abnormality has occurred, an error display similar to the above is displayed on the display 14 in step S8. If no other abnormality has occurred in step S7, the control device 23 proceeds to step S9 and sets the state in which the data from the host machine H can be received, that is, the online state, and notifies the host machine H to that effect. Then, while displaying online on the display unit 14, the error display and offline display are turned off.

As described above, in the present invention, when it is detected by the lid switch DS that the lid panel D is closed after the paper is replaced, the control device 23 inspects the kitchen printer KP for an abnormality including the insertion state of the paper 2. If it is normal, the data from the host machine H can be received, so that it is not necessary to press the online switch 11 after replacing the paper 2 as in the conventional case, and the paper replacement work can be facilitated. In addition, it is possible to avoid occurrence of delay in recovery due to forgetting to press the online switch.

In the embodiment, the sales registration device used in a restaurant has been described as an example, but the present invention is not limited to this, and the present invention is effective in a sales registration device used in various stores.
