Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to electronic toll scales.

[0002]

2. Description of the Related Art Conventionally, there is an electronic charge balance equipped with a printer for printing the measurement result.

[0003]

However, since only one printer is provided, only one of the label and the receipt can be issued, and the printer cannot be used for multiple purposes.

The present invention has been made in view of the above points, and it is possible to select a sales form such as issuing a label while weighing and issuing a receipt or printing a sales statement as necessary. Moreover, it is an object of the present invention to provide an electronic charge balance that can form a main body with a low height and a small depth even if two printers are provided.

[0005]

[Means for Solving the Problems] In front of a main body having a weighing unit
An inclined surface is formed on the surface, and the inclined surface is formed inside the main body.
In addition, the first printer and the second printer are vertically arranged and attached, and the first printer and the second printer are attached above the inclined surface.
The second printer is formed below the inclined surface, forming the issuing port.
The issuance port is formed, and the first portion is provided above the inclined surface.
The printer's issuing port is formed below the inclined surface.
Formed the issue port of the second printer .

[0006]

Therefore, it is possible to select a plurality of sales forms such as weighing by the weighing unit, issuing a label by the first printer, and issuing a receipt by the second printer, if necessary. Moreover, the first pudding
The second printer and the printer
The components of each printer are
Can be installed to make effective use of the entire space inside the main unit
It is possible to arrange the parts used, which allows the main body
The height can be reduced and the depth can be reduced to achieve miniaturization .

Pulleys 59 and 60 for transmitting the rotation of the platen to the platen 50 and a belt 61 are provided. The head plate 63 for fixing the thermal head 62 as a print head having the same specifications as the above-mentioned thermal head 41 is provided with two flanged pins 64 upright, and the flange portions of these flanged pins 64 are inserted. A head support plate 67 having an opening 65 and a notch 66 that engages with a small diameter portion of the flanged pin 64 is provided. The head support plate 67 and the pressing plate 68 are connected to the support shaft 53.
It is rotatably fitted in. A spring 69 is held by a screw 68a screwed to the head support plate 67. Further, the pin 70 erected on the support plate 49 is elastically engaged with the pin 71 erected on the side surface of the pressing plate 68 by the pressure of the spring 72, thereby fixing the pressing plate 68 in place. A set lever 73 that applies the pressure of the spring 69 to the head support plate 67 is rotatably held. Further, a pressing plate 74 for pressing the head plate 63 to keep the small diameter portion of the flanged pin 64 and the notch 66 in engagement with each other is attached to the head supporting plate 67 with a screw 75.
A sawtooth-shaped blade 76 is formed on the edge of the blade, and a cutter 77 approaching the blade 76 is screwed to the support plate 49.

Next, a circuit diagram is shown in FIG. CPU78
A decoder 79, a RAM 80, a ROM 81, an I / O 82, a keyboard display unit controller 83, and printer controllers 84 and 85 are provided. The keyboard 4 and the display unit 4a are connected to the keyboard display unit controller 83. Printer controller 8
Reference numerals 4 and 85 respectively control the first and second printers 10 and 13.

[0013] In this arrangement, the supply shaft 12 numerous label 86 affixed to the elongated backing sheet 87 (use
(Paper) is wound and mounted in a roll shape, and the receipt paper 88 (paper) wound in a roll, for example, is placed on the hopper 14. The keyboard 4 is used to input the unit price of the product. The merchandise is weighed by placing it on the tray 2, and the measured value, unit price, price, etc. are displayed on the display unit 4a and printed by the first and second printers 10 and 13. After printing, the platens 33, 50 and the winding shaft 28 rotate, and the mount 87 is bent by the label peeling body 89 (see FIG. 5), so that the label 86 is peeled from the mount 87 with the printing surface facing upward, and the issuing port 5
Since the receipt paper 88 has a curl, it is projected from the issuing port 6 with the printing surface facing the front. If the receipt paper 88 protruding from the issuing port 6 is pulled downward, it is cut by the blade 76 of the pressing plate 74, and if pulled upward, it is cut by the cutter 77 and issued as a receipt. Then, the first
A winding shaft 28, etc., which constitutes a winding mechanism, is connected to the linter 10.
However, the winding shaft 28 is connected to the first printer 10 and the second printer 10.
It can be installed within the range of height with the linter 13.
Therefore, the height of the main body 1 should be the same as that of the first printer 10 and the second printer 10.
It is sufficient to arrange the printer 13 and the winding mechanism.
The height of the main body 1 is not increased even if the
In addition, the print head of the first printer 10 is positioned above the paper.
The print head of the second printer 13 below the paper.
Because they are located,
In the case of
Between the two, the print head and its associated mechanical parts and
Since there is no need to provide space for opening,
From the point of view, the main body is not raised. Also, the front of the body
As an inclined surface, and the first printer 1 along the inclined surface.
0 and the second printer 13 are arranged below the inclined surface.
Since the issuing port 6 of the second printer 13 is formed in
The space inside the body 1 can be used effectively,
The operation part is provided on the inclined surface of the main body 1 and
A first printer 10 and a second printer 13 on one side of the unit
Since the top and bottom are arranged, the overall shape is simplified and the operation is
The sex is also good.

In this case, the step motor 38 that rotates the platen 33, the DC motor 22 that drives the winding shaft 28, and the thermal head 41 are controlled by the printer controller 84, and the step motor 5 that rotates the platen 50 is controlled.
8 and the thermal head 62 are a printer controller 85.
Controlled by.

Since the printer 10 has two printers 10 and 13 each time a merchandise item for sale is weighed, the printer 10 issues a label 86 corresponding to the merchandise item. Can be issued. Further, instead of issuing the receipt, the daily sales details can be recorded. The user freely decides which one to select.

If only the label issuing function is required, the second printer 13 can be easily removed by removing the mounting screw 16 and the notch 55 from the claw 15. This is extremely advantageous for the production management because the manufacturer of the electronic charge balance can easily change the model.

Further, by setting the specifications of the thermal heads 41 and 62 to be the same, a common print buffer can be used.

Further, the head plate 42 and the pressing plate 43 of the upper printer 10 do not rotate below the platen 33, and the head supporting plate 67 of the lower printer 13 is provided.
Since the pressing plate 68 does not rotate above the platen 50, the hopper 14 can be installed in a narrow space between the printers 10 and 13 to contribute to downsizing of the entire apparatus.

As described above, according to the present invention , the inclined surface is formed on the front surface of the main body having the measuring portion, and the inclined surface is formed inside the main body.
Mounting by placing the first printer and the second printer along a slope in the vertical direction, the first flop above said inclined surface
Forming the issuing port of the linter, and below the inclined surface, the second
Since the issue port of the printer is formed , the weighing unit measures the weight, and for example, the first printer issues the label, and the second printer issues the receipt as necessary. Moreover, the first printer and the second printer do not move in the front-back direction.
The components of each printer are
It is possible to arrange it by shifting it backward, and
It is possible to place parts that effectively utilize the entire
This reduces the height of the main unit and the depth to reduce the size.
