Abstract
The utility model discloses a kind of bar-code printer, comprise the thermal head and the platen roller that contact with the back side with paper surface respectively, and label edges checkout gear, described label edges checkout gear is arranged on the downstream position of the described printer of the residing throughput direction along described paper of described thermal head.According to bar-code printer of the present utility model, the downstream position of the printer by the throughput direction at the set paper of thermal head arranges label edges detecting sensor, spacing distance between label edges detection position and typing position is shortened, reduced the print start position deviation causing because of paper sheet delivery error.
Description
Technical field
The utility model relates to bar-code printer.
Background technology
At present, the label edges detecting sensor of bar-code printer is arranged at the upstream side of thermal printing head conventionally, and the position of this upstream side need guarantee not interfere with the route of Transfer ribbon.Because position (being label edges detection position) and the spacing distance between the position (being typing position) at thermal printing head place at label edges detecting sensor place are longer, so may exist because being printed the impact of the convey error in paper feeding process, cause the position of print start to compare the excessive defect of deviation with optimum range.
The content of utility model
Given this, the purpose of this utility model is to provide a kind of bar-code printer, is intended to solve the impact evade because of convey error and causes print start position to occur the defect of deviation.
The concrete technical scheme that the utility model adopts is: a kind of bar-code printer, comprises the thermal head and the platen roller that contact with the back side with paper surface respectively; And label edges checkout gear, described label edges checkout gear is located at the downstream position of the set described printer along described print paper paper feed direction of described thermal head.
In above-mentioned bar-code printer, described label edges checkout gear is arranged on described thermal head.
In above-mentioned bar-code printer, described label edges checkout gear is arranged on upstream one side of described thermal head.
In above-mentioned bar-code printer, described thermal head is placed in thermal head installing component, and described label edges checkout gear is arranged on described thermal head installing component.
In above-mentioned bar-code printer, described label edges checkout gear is placed in upstream one side of described thermal head installing component.
In above-mentioned bar-code printer, described label edges checkout gear is label edges detecting sensor.
In above-mentioned bar-code printer, described label edges detecting sensor is LED sensor.
In above-mentioned bar-code printer, also comprise paper roll, described print paper be fixed on described paper roll, by rotating the spool of described paper roll, described print paper is delivered between described thermal head and described platen roller.
In above-mentioned bar-code printer, also comprise heat transfer colour ribbon, described heat transfer colour ribbon is connected with described label edges detecting sensor, and described label edges detecting sensor detects the label edges of described print paper by described heat transfer colour ribbon.
In above-mentioned bar-code printer, also comprise paper roll outgoing position adjusting device, described paper roll outgoing position adjusting device is connected with described paper roll, described in described printer according to the different outgoing positions of adjusting described paper roll of the kind of heat transfer colour ribbon.
According to bar-code printer of the present utility model, by label edges detecting sensor being set on the parts at thermal head or thermal head installation thermal head, spacing distance between label edges detection position and typing position (thermal head) is shortened, reduced the print start position deviation causing because of paper sheet delivery error.
Accompanying drawing explanation
The accompanying drawing that forms a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the scheme of installation of the label edges detecting sensor of bar-code printer of the present utility model.

The specific embodiment
It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the utility model can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
Below, with reference to accompanying drawing, to describing for implementing embodiment of the present utility model.
Bar code printer as shown in Figure 1, comprises the both sides thermal head 4 and the platen roller 3 that are distributed in print paper plane; The residing downstream position of thermal head 4 is provided with label edges detecting sensor 6, and label edges detecting sensor 6 is preferably TRN or LED sensor.
The spool that passes through rotation paper roll that is fixed on the print paper of paper roll 2 is delivered to thermal head by print paper and prints.On thermal head 4, configuration detection goes out the label edges detecting sensor 6 of label edges on paper roll 2, and then detects label gap by heat transfer colour ribbon 1.
In addition, also can first thermal head 4 be placed in thermal head installing component 5 for thermal head 4 configuration thermal head installing components 5, then label edges detecting sensor 6 is installed on thermal head installing component 5.
Heat transfer colour ribbon 1 is connected with label edges detecting sensor 6, and diathermanous Transfer ribbon 1 can detect the label edges of print paper.The label edges of different types of heat transfer colour ribbon 1 correspondence is different with typing position, and label edges is wherein measured by described label edges detecting sensor, and typing position is the installation site of thermal head 3.Printer is adjusted the output of paper roll 2 according to the difference of heat transfer colour ribbon a kind.
In addition, bar-code printer of the present utility model also comprises paper roll outgoing position adjusting device, and paper roll outgoing position adjusting device is connected with paper roll, described in printer according to the different outgoing positions of adjusting paper roll of the kind of heat transfer colour ribbon.
In sum, the label edges detecting sensor that compares to prior art is positioned at the trip on the upper side of printer substantially, the configuration structure of above-mentioned two kinds of forms of the present utility model shortens the spacing distance between label edges detecting sensor 6 and thermal head 3, the print start position deviation causing because of the impact of convey error obviously reduces, and has optimized end-user experience.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
