Description

[Detailed description of the invention] This invention is a printing device that calculates the price of the object to be weighed from the measured value and a preset unit price, and prints the name, weight, unit price, price, etc. of the object to be weighed on a receipt or label. Regarding the fee scale having.

Conventionally, when weighing, data related to weighing, such as the unit price of the object to be weighed and the tare weight value used for weighing, is manually set by the scale operator based on a comparison table of unit prices, tare weight values, etc. It is.

In this way, resetting the data every time the object to be weighed changes is not only cumbersome and reduces work efficiency, but also loses accuracy as the number of objects to be weighed increases.

Therefore, the present invention was developed in view of the above-mentioned drawbacks, and it calculates the price of the object to be weighed from the measured value and a preset unit price, prints the weight, unit price, and price on printing paper, and The product name of the object to be weighed is printed on the printing paper by the product name stamp plate attached correspondingly to the product name stamp plate, and the unit price of the object to be weighed is printed on any other side of the product name stamp plate other than the printing part. A magnetic recording medium is provided with data such as
The price scale body is provided with a reproducing means for reading data from the magnetic recording medium of the attached product name stamp plate and executing the unit price setting, thereby providing a price scale with high work efficiency and capable of accurate pricing. It is something.

An embodiment of the present invention will be described below based on the drawings.

Outputs a signal to.

Therefore, the limit switch 22 is arranged so as to detect the state of the link 18 [displacement 0°] when the holding part 14 is closest to the rotating shaft 17 of the motor 16, and the rotating shaft 17 rotates clockwise. In this case, the link 18 at the start of the operation is located at a position slightly beyond the displacement 0° (the imaginary line position in FIG. 5).

23 detects the position of the link 18 (solid line position in FIG. 5) where the holding part 14 passes through the state where it is the most distant from the rotating shaft 17 and the holding part 14 starts a backward movement in the direction of arrow C. This is the installed limit switch.

The price of the object to be weighed is calculated from the weight signal G output from the weighing section 2, and a price signal pigeon corresponding to the price of the object to be weighed is output.

39, 40, and 41 are weight, unit price, and price display sections, respectively, and weight signal G1 is a unit price a1 stored in the memory 37, and price signal M0 is a weight unit price and price display section 4 of the operation panel 3, respectively. displayed digitally.

Reference numeral 42 denotes a control unit of the printing device, which drives the arm 43 on which the product name stamp plate 9 is attached at the timing of the balance signal B when the weighing unit 2 detects that the weighed values are balanced, and prints the product name on the label 44. At the same time, the weight value, unit price, and price of the object to be weighed at that timing are printed on the label 44.
Issue.

First, the case where the unit price of the object to be weighed whose product name is printed on the printing plate section 10 on the product name stamp plate 9 will be explained.

Holding the handle H of the product name stamp plate 9, attach it to the holding part 14 of the recording/reproducing section 12 so that the magnetic tape 11 on the front side of the product name stamp plate 9 comes into contact with the magnetic head 13.

Here, assuming that the mode changeover switch SW3 of the numeric keypad 8 and the changeover switches sw, , sw2 of the magnetic head 13 are switched to the writing position, then the desired unit price, for example, 1,235C yen] is inputted using the numeric keypad 8. memory 28
1,235 C yen] and then operate the start switch 21 to start the motor 16 and start the magnetic tape 1.
1 and the magnetic head 13 are moved relative to each other.

When the holding section 14 enters the backward movement, a timing signal generating section 26 is generated on the control track CH1 of the magnetic tape 11.
The start signal ST output by the control head 25
written by.

Furthermore, after the predetermined time t
A digit designation signal SK that designates the digit of $9 is output to the gate 29, and is sent to the data track C of the magnetic tape 11 via the data recording section 31 and the data head 24. The unit price 1,235 (yen) held in the memory 28 is written.

At this time, the digit designation signal S is sent to the control rack CH1 via the control signal recording section 32 and the control head 25.
K is written.

When the motor 16 rotates once, the written contents of the memory 28 are automatically reset, and the motor 16 returns the holding section 14 to the starting position and stops.

This completes the data write operation, and Figure 7 shows 1 and 2.
35 (circle) is recorded on the magnetic tape 11. FIG.

Next, when carrying out weighing using the product name stamp plate 9 on which data has been recorded, hold the handle H and hold the magnetic tape 1 of the product name stamp plate 9 on the holding part 14 in the same way as when writing the data.
1 is attached so as to be in contact with the magnetic head 13, and after switching the changeover switches SW□ and SW2 to the reading side, the start switch 21 is operated to start the motor 16, and the magnetic head 13 and the reproducing section 33 are connected. The recorded contents of the magnetic tape 11 are read through the magnetic tape 11.

The gate 36 detects that the holding section 14 has entered the backward motion, and from the time when the control signal reproducing section 35 reproduces the start signal J, the digit of the output signal of the data reproducing section 34 is changed to the reproduction signal of the control track CH□. It is specified and output to the memory 37 in digit series-bit series.

The read data (unit price 1°235 [yen]) is immediately displayed on the unit price display window 5 via the unit price display section 40.

This completes the automatic unit price setting.

Next, the product name stamp plate 9 that has been read is removed from the holding unit 14, and the product name stamp plate 9 is mounted on the arm 43 of the printing device so that the printing plate unit 10 can print it, and placed on the weighing tray 1. to start weighing.

When the weighing section 2 outputs the balance detection signal B, the weighing value, unit price, price, and product name at that time are printed on the label 44 by the printing device.

Magnetic tape 11 with unit price affixed to product name stamp plate 9 in this way
The unit price of the object to be weighed can be automatically set by recording the contents and reading the contents at the time of weighing.

Furthermore, since it is a magnetic tape, data can be easily rewritten by switching the reading magnetic head 13 to a recording section.

In the above embodiment, the data written on the magnetic tape 11 was only the unit price of the object to be weighed, which is printed by the printing plate part 10 of the product name stamp plate 9, but the product name code, tare weight value, etc. can also be written and used together with the unit price. It is also possible to do so.

Further, although data is written on the magnetic tape 11 in bit series, the present invention is not limited to this, and data can also be written in bit parallel.

Further, in the above embodiment, a mechanism section for causing relative movement between the magnetic tape 11 as a magnetic recording medium and the magnetic head 13 provided on the product name stamp plate 9, a reproducing section 33, and a gate 36 read out the contents of the magnetic recording medium. It is configured as a reproduction means.

As explained above, according to the present invention, a magnetic recording medium on which data such as the unit price of the object to be weighed is written is provided on any side of the product name stamp other than the printing part, and it is attached to the price scale body. By providing a reproduction means for reading data from the magnetic recording medium of the product name stamp plate and setting the unit price, various data related to weighing can be set extremely easily and accurately. Even if the number of items increases, work efficiency will not decrease.

Furthermore, since the data portion is recorded on a magnetic recording medium, its contents can be easily changed.
