Embodiment 1

[0014] above as figure 1 , figure 2 A calculator with distance measuring function shown includes a housing 1 and a display screen 2 arranged on the housing 1, and also includes an infrared distance measuring device 3 and a distance measuring switch 4 arranged on the housing 1; An AD conversion circuit and a single-chip microcomputer in the housing 1;

[0015] The calculator with the distance measuring function has the distance measuring function while retaining the calculation function of the calculator. At the same time, it can measure the distance while calculating, which is not only convenient and practical, but also greatly increases the application of the calculator, giving full play to the multi-purpose function Efficiency makes the calculator more practical.

Embodiment 2

[0017] Above-mentioned infrared distance measuring device 3 is used for measuring distance signal, and signal is sent to AD conversion circuit; Said AD conversion circuit is used for receiving the signal that infrared distance measuring device 3 sends, and digitizes, then sends signal to single-chip microcomputer; The single-chip microcomputer is used to receive the signal sent by the AD conversion circuit, or the control instruction of the ranging switch 4, and execute the instruction and control the display screen 2 to display distance information; the above-mentioned calculator with the ranging function also includes a power supply circuit, and the power supply The circuit is connected in parallel with the original power supply circuit of the calculator, and provides power for the infrared distance measuring device 3, the AD conversion circuit and the single-chip microcomputer.

Abstract

The invention belongs to the technical field of electronic products, in particular to a calculator with the distance measurement function. The calculator with the distance measurement function comprises a shell body, a display screen, an infrared distance measurement device, a distance measurement switch, an AD switching circuit and a single chip microcomputer, wherein the display screen, the infrared distance measurement device and the distance measurement switch are arranged on the shell body, and the AD switching circuit and the single chip computer are arranged in the shell body. The calculator with the distance measurement function maintains the calculating function of the calculator, has the distance measurement function, can measure the distance while calculating, is convenient and practical, enables the application of the calculator to be increased, fully plays the multi-purpose function, and enables the practical situation of the calculator to be more widely.

Description

technical field [0001] The invention belongs to the technical field of electronic products, and in particular relates to a calculator with a distance measuring function. Background technique [0002] A calculator (calculator; counter) generally refers to an "electronic calculator", a hand-held machine that can perform mathematical calculations. It has an integrated circuit chip, but its structure is simple, much simpler than that of a modern computer. It can be said to be the first generation Electronic computers (computers) have weaker functions, but are more convenient and cheap. They can be widely used in commercial transactions and are one of the necessary office supplies. Existing calculators can only perform mathematical operations, do not have a distance measuring function, and cannot play a multi-purpose function, which greatly limits the use of calculators. Contents of the invention [0003] The purpose of the present invention is to overcome the problem that ex...
