Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic charge balance for face-to-face sales, which is used for weighing products.

2. Description of the Related Art In this type of electronic toll scale, the weight of a product is measured and the product is sold face-to-face at a price according to the weight, but in the conventional one, only one printer is built in. Absent. As described above, in the case of a single printer, there is only a single function of issuing a receipt or issuing a label.

Therefore, in order to obtain two kinds of printed matter and journal recording, an electronic fee scale incorporating two printers has already been proposed by the present applicant.

Problems to be Solved by the Invention In such an electronic charge balance with two built-in printers, since each printer is independent, when performing test printing or error check. Is very troublesome because it is necessary to give a command to each printer.

Means for Solving Problems In an electronic charge balance for face-to-face sales having a first printer and a second printer and having a display unit for displaying characters, a test pattern of two types of printers is tested. Printing and error information display are continuously performed for each printer.

Function Even if there are two printers, the test pattern is printed and the error information is displayed continuously for each printer during the test, so it is only necessary to give the test command once. Improve and never forget to check the two printers.

Embodiment An embodiment of the present invention will be described with reference to the drawings. First, a pan 2 is provided on the upper surface of the balance main body 1, and a weighing section using a load cell, which will be described later, is provided inside. A key panel 3 is provided in front of such a scale main body 1, and a first printer 4 is provided on a side portion of the key panel 3.
Is provided on the upper side, and the second printer 5 is provided on the lower side. Further, a mode switch 6 for setting various modes is provided below the scale main body 1.

Thus, the first printer 4 is for label printing. The long mount 8 on which the labels 7 are attached at regular intervals is wound into a roll and attached to the supply shaft 9, and the sensor 1
0, platen 11, release plate 1 for rapidly bending the mount 8
2. The mount 8 is wound around the winding shaft 14 via the guide shaft 13. A thermal head 15 is provided so as to face the platen 11, and a label issuing port 16 is provided.
A label detector 17 for detecting the leading edge of the label 7 peeled off by the peeling plate 12 is provided in the vicinity of. The platen 11 is driven by a motor 18.

Then, the second printer 5 is for issuing a receipt. That is, the receipt paper 19 wound in a roll shape is held in a free state in a semi-arcuate holder 20 that expands upward,
The platen 22 driven by the motor 21 and the platen 22
The receipt paper 19 is inserted between the thermal head 23 and the thermal head 23 located below, and is sent out as a receipt 25 from the receipt issuing port 24 to the outside.

Next, a pillar 26 is provided upright on the back of the scale main body 1, and a display portion 27 is provided on the pillar 26. This display 27
The front and back sides are the display surfaces 28, and a large number of characters and other considerable information can be displayed.

Next, the internal circuit will be described. First, a CPU 29 is provided, and a load cell 31 as a weighing unit is connected to the CPU 29 via an analog-digital converter 30.
Next, an I / O block 32 is connected to the CPU 29, and the printers 4 and 5 are connected to the I / O block 32. In addition, the I / O block 32 is connected to the display unit 27, and is also connected to a switching switch 33 such as a display switch for semi-fixedly setting various modes and an interface 34 for in-line connection. ing.

In such a configuration, the operation will be described based on the flow chart. The operation shown in FIG. 5 is the whole operation. First, the memory is cleared after the start, the I / O initialization is performed, the changeover switch 33, that is, the depth switch is read, and the mode switch 6 is read. Then, it is checked whether or not the mode switch 6 is in the OFF state. This mode switch 6
To be OFF means to be in a locked state, and cannot be set or registered, and is in a weighing state.

If the mode switch 6 is not OFF, the segment check of the numerical display portion of the display portion 27 is performed by repeating 0 and 1 and extinguishing.

If the mode switch 6 is not OFF, the scale data is read, the scale data is processed, the display unit 27 is turned on, the display switch is read, the mode switch 6 is read, the scale data is read, and the scale data is processed. Repeat the routine. When the mode switch 6 is released from OFF in the process, the segment check of the numerical display portion of the display portion 27 repeats 0 and extinguishing. Then, when the balance data becomes stable, the zero range check and the power failure are detected, and the process proceeds to the main flow.

Next, the main flow will be described with reference to FIG. First, the mode check is performed, the front switch check is performed, and then it is checked whether or not the mode switch 6 is in the OFF position. If the mode switch 6 is not OFF, see if any key is pressed. At this time, if it is not the registration mode, key processing corresponding to the pressed key is performed, and a lamp display and a necessary display are performed. If the registration key is pressed, the key is processed, but if the test key is further pressed, the routine shown in FIG. 7 described later is executed.

If the mode switch 6 is not OFF and the key is not pressed, the scale data is read, the scale data is processed, and the auto zero process is performed. Here, the mode switch 6 is checked again, and if it is not OFF, the data from the quartz timer is read.

Then, it is checked whether or not the net calculation is necessary. If the net calculation is necessary, gross calculation is performed and auto clear is performed. Net tare is subtracted from the gross to calculate net, and the auto clear condition check is performed.

Also, check whether or not price calculation is necessary, and if necessary, calculate the price by multiplying the net weight by the unit price, perform the lamp display and the necessary display, and then print the label.

Next, in the routine shown in FIG. 6, when the test key is pressed, the printer 5 outputs the test print such as drawing a large number of diagonal lines, and if there is an error, an error message is displayed. It is displayed on the display unit 27, and the display is automatically canceled after 2 seconds. Next, output from the printer 4 and perform a test print such as drawing a large number of diagonal lines, and if there is an error, display an error message on the display unit 27 and operate the erase key to cancel the error display. It Such an operation is continuously performed for the two printers 4 and 5.

As an error message, the thermal head 15,2
3 is "Head Up" separated from Platens 11 and 22.
It is a message that says, "It's a paper end,""The cassette is wrong," or "Head power error."

As described above, the present invention is an electronic charge balance for face-to-face sales, which includes the first printer and the second printer and is provided with a display section for displaying characters. Since the test pattern is printed and the error information is displayed continuously for each printer, even if there are two printers, the test pattern is printed and the error information is displayed for each printer during the test. Since the test commands are performed continuously, it is only necessary to give the test command once, which improves the operability of the test command and never forgets to check the two printers.
