Abstract
The utility model provides a bill printer, including print module, processing module, power module, analog -to -digital conversion module, earphone joint socket, processing module and print module, analog -to -digital conversion module are connected, and analog -to -digital conversion module is connected with earphone joint socket, power module and print module, processing module, analog -to -digital conversion module are connected, analog -to -digital conversion module is used for converting the analog signal type information that the earphone connects the socket into the data signal type information, processing module is used for reading the data signal type information and prints according to data signal type information drive print module. The utility model discloses an analog signal that the earphone connects realizes the receipt to the type information, and the drive is simple, low cost, convenient to use.
Description
Technical field
The utility model relates to printer technology field, particularly relates to a kind of bill printer.
Background technology
Wired joint that existing receipt printer adopts, as USB joint, serial ports etc., these joints are not easy to be connected with hand-held devices such as mobile phones, thus mobile phone cannot use printer, can connect printer by the wireless mode as bluetooth, WIFI at some, but these wireless module costs are high, drive complicated, also to match, use suitable trouble.
Summary of the invention
The technical problems to be solved in the utility model, is to provide a kind of bill printer, solves hand-held device and uses the troublesome problem of printer.
The utility model is achieved in that a kind of bill printer, comprise print module, processing module, power module, analog-to-digital conversion module, Earphone joint socket, described processing module and print module, analog-to-digital conversion module connects, analog-to-digital conversion module is connected with Earphone joint socket, described power module and print module, processing module, analog-to-digital conversion module connects, described analog-to-digital conversion module is used for the analog signal type information of Earphone joint socket to be converted to data signal type information, described processing module is for reading data signal type information and driving print module to print according to data signal type information.
Further, described processing module is MCU.
Further, described Earphone joint socket is 3.5mm Earphone joint socket.
The utility model tool has the following advantages: realize the reception to type information by the analog signal of Earphone joint, drives simple, with low cost, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
By describing technology contents of the present utility model, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
Refer to Fig. 1, the present embodiment provides a kind of bill printer 1, comprise print module 10, processing module 11, power module 12, analog-to-digital conversion module 13, Earphone joint socket 14, described processing module and print module, analog-to-digital conversion module connects, analog-to-digital conversion module is connected with Earphone joint socket, described power module and print module, processing module, analog-to-digital conversion module connects, described analog-to-digital conversion module is used for the analog signal type information of Earphone joint socket to be converted to data signal type information, described processing module is for reading data signal type information and driving print module to print according to data signal type information.Wherein, print module is for realizing type information to print to paper.Power module is used for power supply.In use, the line that the hand-held devices such as mobile phone can be headset plug by two ends is connected on this printer the utility model, and then type information is sent to printer by earphone by hand-held device.Processor in printer receives type information by analog-to-digital conversion module, and rear drive print module prints type information, namely completes the print job of hand-held device.The utility model carries out information transmission by Earphone joint, and cost is low, drives simple.Wherein, the translation-protocol of data signal type information and analog signal type information can be multiple, and the conversion of analog signal and data signal also has multiple implementation, is not repeated herein.
In certain embodiments, described processing module is MCU.Described Earphone joint socket is 3.5mm Earphone joint socket, is applicable to most handheld device.
The foregoing is only embodiment of the present utility model; not thereby scope of patent protection of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
