Description

[Detailed explanation of the idea] This invention relates to electronic scales.

This type of device uses a measuring element using a load cell that measures the load while converting it into an electrical signal, and a slit disk that detects the movement of an actuating body connected to the tray to measure the load on the tray electrically. It has a measuring element that measures while converting it as a signal. In addition, other elements such as operation sections such as various keys, store display section, customer display section, power supply section, calculation section, AD conversion section, external output section, etc. are required, but these are installed on individual PCs. It is held while being electrically connected to the board. Therefore, the number of connectors that connect PC boards increases, and the number of fastening members that fasten PC boards also increases, making assembly and inspection extremely troublesome.

The purpose of this invention is to create an electronic scale that has a small number of parts and is easy to assemble and inspect.

This idea includes a measuring element that measures the load on the tray while converting it into an electrical signal inside the main body, which has display windows formed on the front and rear sides, as well as elements such as the power supply section, calculation section, and AD conversion section. A store surface display section and a customer surface display section each display weight, unit price, price, etc., by arranging PC boards, which are electrically connected and held and extending in the front-rear direction, and facing the display window, respectively. is electrically connected to and held at the front or rear of the PC board, and an operating section installed on the front side of the main body is held while electrically connected to the front of the PC board. It is.
In other words, by connecting and holding the operation section, store display section, customer display section, and most other elements to a common PC board, the number of PC boards can be reduced to one, which makes assembly easier. The structure is such that inspection work can be easily carried out in a short amount of time.

An embodiment of this invention will be explained based on the drawings.
Reference numeral 1 denotes a main body, and the main body 1 is formed by enclosing a space above a base 2 with an upper opening made of aluminum die-casting and surrounding it with a cover 3 with a lower opening. At the center bottom of the base 2 are a load cell 4 and a transformer 5, which are measurement elements.
A supporting column 8 of a tray frame 7 that holds the tray 6 is connected to the upper surface of the load cell 4 while passing through the cover 3 . On the front of the cover 3, there is an operation section 9 with a large number of keys, switches, etc.
An opening 10 for protruding and a display window 12 facing the store surface display section 11 are formed, and a display window 14 facing the customer surface display section 13 is formed on the rear surface.

Next, a PC board 16 having an opening 15 formed therein for letting the support column 8 and the load cell 4 escape is provided inside the main body 1 so as to extend in the front-rear direction and downwardly in the front. The operating section 9 and the store surface display section 11 are electrically connected and held in front of the PC board 16, and the customer surface display section 13 is electrically connected to the rear lower surface. In addition, elements such as a power supply section, a calculation section, and an AD conversion section (not shown) are electrically connected to and held in the external output section 17, respectively.

In such a configuration, when an object is placed on the tray 6, the load cell 4 converts the load of the object into an electrical signal and measures it, and the result is displayed on the store surface display section 11 and the customer surface display section 1.
3 are displayed at the same time. These store display parts 1
1, the customer display section 13, the operation section 9, and other power supply sections.
Most of the elements such as the calculation section, AD conversion section, external output section 17, etc. are held on the common PC board 16, so only one PC board 16 is required.
Assembly and inspection are easy.

Figure 2 shows the PC board 16 in accordance with the shape of the cover 18.
is held in a low horizontal position. Therefore, the transformer 5 is fixed to the upper surface of the cover 18 to avoid interference with the PC board 16.

This idea, as mentioned above, allows the number of PC boards to match by electrically connecting and holding the operation section, store display section, customer display section, and most other elements to a common PC board. This has the effect that assembly and inspection work can be easily performed in a short amount of time.
