What Is a Terminal Unit?

A terminal is a computer display terminal and is an input and output device of a computer system. Computer display terminals are produced with the centralized processing mode of the host era, and continue to develop with the development of computing technology. The terminal is also called a sharing device, a sharing device, a computer sharing device, and a computer sharing device.

The terminal is just a

Terminal is currently the most common lottery betting terminal

Taking Sile SN2000CL integrated lottery betting machine ^[2] as an example: The structure of the most commonly used lottery betting terminal in China at present is mainly divided into these parts:

(1) Operation display

This area is used by operators to perform the following operations: 1. Connect with the switchboard; 2. Obtain information; 3. Enter lottery bets; 4 Lottery redemption; 5. Debug settings.

In the initial design, this screen was mainly used as a display output device. With the development of technology and technological progress, especially the development of screen touch technology, the display screen has gradually assumed the role of an input device for Perform touch input. Operators can perform most operations directly through the screen, and various functions and keys can be displayed on the screen. This operation is more intuitive and convenient. However, since the position of the screen is generally high, and the response time and response efficiency of the touch screen are not as good as the keyboard, it is not suitable for the operator to perform long-term continuous work.

(2) Keyboard area

This module is the main input device for the operator, divided into numeric keypad and function keypad. Due to the popularity of computers, people are no strangers to keyboard input. The keyboard of the computer is more complete and complete, and the betting machine itself has fewer functions, so its keyboard functions are correspondingly less. Generally only include numeric keys and a few keys such as "redemption", "query", function switching, custom functions and so on.

(3) Lottery printer

Used to print out lottery tickets needed by lottery buyers. Existing models of lottery printers are thermal printers, which have no radiation damage to the human body. There is a separate movement. The movement is actually the same as a thermal printer that prints small tickets at the cashier at the supermarket. There are two ways to place lottery printers: plug-in and built-in. Their movements are no different, they are just installed inside or installed as a separate printer outside.

Factors Needing Attention in Terminal Design

Industrial design is the design for manufacturing industrial products. It includes the entire process of product external and internal design, and has the most direct impact on the appearance and performance of products, the use of production technology, and brand building.

Most of the products sold in the market can be improved in some ways through better industrial design. All the products that people use to manipulate or see depend on industrial design to a large extent for their commercial success. There are several aspects to evaluating the quality of an industrial design of a shaped product:

1. The user interface of a practical product should be secure, easy to operate, and intuitive.

2. Appearance shape, line, proportion and color should give people a pleasing feeling. This mainly evaluates the appeal of the product to customers. For example: Is the product attractive? Is it exciting? Can owning the product bring pride to customers?

3. Ease of maintenance The design of the product must be easy to maintain and repair.

4. The form and characteristics of low-cost products have a great influence on the production costs of processing equipment and products.

5. The design of communication products should fully express the design concept through visual characteristics.

6. Product differences mainly evaluate the uniqueness of the product and its consistency with the corporate image. Products with stable markets and mature technologies rely heavily on industrial design to create differences.

7.Environmental issues require that when designing to create people's diverse values, attention should be paid to making these values always harmonious and coordinate with each other in the context of human, society, and the environment, and strive to find their common domain. Only in this way can industrial design truly serve society.
