Description

Magnetic bar code scanner applied to smart phone

Technical Field

The present invention relates to a magnetic barcode scanner applied to a smart phone, and more particularly, to a magnetic barcode scanner capable of preventing a USB connector from being easily broken or damaged by connecting a barcode scanner and a circuit of a smart phone in a magnetic manner.

Background

At present, computers are very common, and in order to meet various applications and requirements, there are desktop computers, notebook computers, tablet computers or mobile computers (mobile computers), wherein the mobile computers can be applied to warehouse management, logistics transportation, intelligent retail, intelligent medical treatment, intelligent manufacturing, etc., and the mobile computers have a small volume, which is generally much more portable than the smart phones on the market. The first type is shown in U.S. Pat. No. 3,340,034 Handheld computer with built-in bar code scanner in FIG. 1, and the second type is shown in U.S. Pat. No. 2, 8,456,428User interface for mobile computing device in FIG. 2, which has no mechanical keyboard and is used instead as a virtual keyboard on a smart phone screen. Both of them are displayed on a screen like a general computer, and the second one has a tendency to replace the first one gradually because the screen is larger, although it is developed later. For example, searching mobile computers by pictures on the network, the second type is slightly more than the first mobile computer, but because the keyboard is small and difficult to input, the mobile computer is equipped with a bar code scanner as an important tool for inputting information.

Nowadays, the smart phone is almost one person, the production quantity is about one thousand times that of a mobile computer, and the performance and the function of the smart phone are higher than those of the mobile computer, so that the cost performance of the smart phone is absolutely higher than that of the mobile computer, and the smart phone can be used as an application program (App) for reading a bar code to become a second type of mobile computer, but compared with a common bar code scanner, the smart phone has the following defects:

1. the number of pixels (pixels) of the smartphone camera is over 10 times higher than that of a general barcode scanner, resulting in a slow decoding speed.

2. The CMOS sensor of the camera of the smart phone is color, the bar code is black and white, and the CMOS sensor of the common bar code scanner is also black and white, so the decoding is faster.

3. The distance of the camera of the intelligent mobile phone is greatly different from near to far, so that the lens of the camera needs time-consuming automatic focusing, the distance of the bar code is relatively small from near to far, and a common bar code scanner uses the lens with fixed focal length, so that the bar code is read quickly.

4. Most of the smart phone cameras employ a Rolling shutter CMOS sensor, and the general barcode scanner may employ a Global sensor (Global shutter CMOS sensor) with a short exposure time and a large movement tolerance.

Barcode scanners are important components of mobile computers. The barcode scanning function of the smart phone is not suitable for mobile computer because of the above disadvantages.

In view of this, the applicant of the present invention previously designed an additional barcode scanner to a smart phone as a mobile computer, and also applied for taiwan patent approval No. M486100 [ mobile barcode information reading system ], please refer to fig. 3 (fig. 1 of the patent), which is a mobile computer composed of a smart phone 101 and a barcode scanner 102. Referring to fig. 4 (fig. 2 of the patent), it can be seen from the drawing that the barcode scanner 102 has a barcode scanner body 1021 at the front and a USB (universal serial bus) male connector 1022 at the rear, the smart phone 101 includes a screen 1011 and a USB female connector 1022, and the mobile computer 10 is formed by inserting the USB male connector 1022 into the USB female connector 1012. The smart phone 101 transmits a control signal and a power source to the barcode scanner body 102 through the USB connector, the barcode scanner body 102 transmits the read barcode information to the smart phone 101 through the USB connector, and the decoding software can be disposed in the barcode scanner body 102 or in a cpu in the smart phone 101. The mobile computer 10 takes advantage of mass production of the smart phone, and the screen 1011 is relatively large, so that it is inexpensive and excellent. However, it has a big disadvantage that when the barcode scanner body 102 is accidentally bumped, the USB male connector 1022 is easily broken or the USB female connector 1012 is easily damaged.

The circuit adapter 1 is a magnetic member and has a USB male connector 11, wherein a plurality of contacts 12 are disposed on opposite sides of the USB male connector 11, and the USB male connector 11 is connected to the plurality of contacts 12 by a circuit. In this embodiment, the circuit adapter 1 includes a magnet.

The bar code scanner 2 has a magnetic member 21 at one end thereof, a plurality of receiving slots 211 are formed in the magnetic member 21, and spring pins 22 are disposed in the receiving slots 211, such that the ends of the spring pins 22 are exposed from the front end of the magnetic member 21, and the spring pins 22 are respectively connected to a circuit 23 formed in the bar code scanner 2. The magnetic member 21 is a magnet, and the magnetic member and the magnet in the circuit adapter 1 have opposite polarities on their connection surfaces, so that they attract each other.

Through the combination of the above components, the magnetic bar code scanner of the smart phone is formed. When the circuit adapter is used, the USB male connector 11 of the circuit adapter 1 is firstly inserted into the USB female connector 31 of the smart phone 3, then the bar code scanner 2 is close to the circuit adapter 1, namely, the bar code scanner is combined together due to the mutual attraction of the magnetism of the circuit adapter 1 and the magnetic piece 21, so that the spring connecting pins 22 are in contact conduction with the contact 12, and when the magnetism of the circuit adapter 1 and the two magnets of the magnetic piece 21 are mutually attracted, the spring connecting pins 22 slightly shrink due to elasticity, and the contact 12 is propped by virtue of the elasticity to ensure that the circuit is well contacted. The power and control signals of the smart phone 3 are transmitted to the barcode scanner 2 through the spring connection pin 22, and the signals of the barcode read by the barcode scanner 2 are also transmitted to the smart phone 3 through the spring connection pin 22, and the decoding software thereof can be disposed in the barcode scanner body 2 or in the cpu in the smart phone 3. As shown in FIG. 6, the whole computer is a mobile computer for various applications. When the barcode scanner 2 is improperly bumped during use, the circuit adapter 1 and the magnetic member 21 will be separated, so that the USB male connector 1 of the circuit adapter 1 or the USB female connector 31 of the smart phone 3 will not be damaged. The bar code scanner 2 is close to the circuit adapter 1 again, and the original shape will be restored again, so as to solve the problem existed in the aforementioned Taiwan patent approval, No. M486100 [ mobile bar code information reading system ].

Fig. 8 is a charging state diagram according to the present invention. As shown in the figure, when the charging device is charged, as in the present embodiment, the circuit adapter 1 is magnetically attracted by a magnetic connector 4 for charging, and the magnetic connector 4 is connected to a general charging seat through a cable 41. Or the circuit adapter 1 is pulled out, and a common smart phone charger is used for charging.

Please refer to fig. 9, which is a perspective view of another embodiment of the present invention. As shown in the figure, the present invention can divide the bar code scanner 2 into two parts for combining. The front section of the barcode scanner 2 is independently a second circuit adapter 2a, the second circuit adapter 2a is provided with a USB female connector 25, and the barcode scanner 2 is additionally provided with a USB male connector 24, which is inserted into the USB female connector 25 through the USB male connector 24 to form the barcode scanner 2 shown in fig. 5. This has the advantage of being easy to manufacture and the disadvantage of using more material.

It is to be understood that the described embodiments are merely a few embodiments of the utility model, and not all embodiments.
