Detailed description of the invention
It should be noted that, in the situation that not conflicting, the feature in embodiment and 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 Fig. 2 to Fig. 4, the embodiment that prevents cylinder deformation mechanism for implementing the utility model is described.
The present embodiment prevents that cylinder deformation mechanism from comprising timing portion 22 and cylinder device of rotation driving 24.Timing portion 22 is for being arranged on the time cycle that under holding state, head roll rotates; Cylinder device of rotation driving 24 is electrically connected with timing portion 22, rotates for timing portion 22 head roll when the cycle time of advent angle of setting.Preferably, timing portion 22 is timer 2 21 or counter.
Can find out, the present embodiment is for solving in printer because printer cover is pushed down the cylinder distortion that cylinder causes, in the time of standby with certain hour interval rotary drum a little, and move termly the place being held down, in this way, eliminate as much as possible distortion, improve print performance.
Further preferably, the present embodiment prevents that cylinder deformation mechanism from also comprising the temperature sensor 20 being electrically connected with timing portion 22.This temperature sensor 20 is for detection of environment temperature; Timing portion 22 changes according to detecting the environment temperature obtaining the time cycle that head roll rotates under holding state.
With reference to Fig. 3, Fig. 3 is that the utility model prevents in cylinder deformation mechanism, and the time cycle that head roll rotates under holding state is with the curve of the variation of environment temperature.As can be seen from Figure 3, ambient temperature is higher, and the time cycle is shorter; Ambient temperature is lower, and the time cycle is longer.
Specifically, prevent in cylinder deformation mechanism at the present embodiment, timing portion also comprises the first controller 222 and the second controller 223 that are electrically connected with timer or counter.The first controller 222 is in environment temperature during higher than first threshold, cycle time expand.Second controller 223 is for during lower than Second Threshold, shortening the time cycle in environment temperature.
That is to say, the present embodiment, by temperature sensor 20, the first controller 222 and second controller 223, is realized the regulation and control of time cycle.This is based on following consideration: in the time that environment temperature is around high, cylinder becomes easy distortion, so need to monitor environment temperature.If temperature is high, make the cycle of traveling roller shorten, if low, extend.
Prevent that cylinder deformation mechanism from also comprising lid open-close condition checkout gear 26; Lid open-close condition checkout gear 26 is for detection of the open and-shut mode of printer cover; Cylinder device of rotation driving 24 is electrically connected with lid open-close state monitoring apparatus 26.The meaning that open and-shut mode checkout gear 26 is set is: as Security Countermeasures, can confirm the open and-shut mode of printer cover and only under the state in closing, make cylinder action.
In addition, in the specific implementation, prevent that cylinder deformation mechanism is also as such system: even the state lower time of printer in the switch of cutting off the electricity supply, if plug is the state in inserting also, also only supply with and have power supply to the needed system of traveling roller, even if the switch of printer also can traveling roller in off-state.
With reference to Fig. 4, Fig. 4 is the workflow diagram that the utility model prevents cylinder deformation mechanism.
First, will prevent that cylinder deformation mechanism from switching on power.Then, carry out the detection of environment temperature.According to the temperature detecting, determine the time cycle, wait for the time that head roll rotates.Timer carries out countdown.When arriving after the time cycle of specifying, counting finishes, and judges by lid open-close condition checkout gear (or title " cover sensor ") whether printer cover closes, and if so, head roll rotates a little angle.
With reference to Fig. 5, Fig. 5 is the structured flowchart that is provided with the utility model and prevents the printer embodiment of cylinder deformation mechanism.
The present embodiment printer comprises the central controller (CPU) of printer, and be connected to each structure on CPU: electric machine controller, print head driver, the ROM that stores time cycle setting table, RAM, input/output end port (I/O port), demonstration, operating portion and, timing portion, communication I/F etc.And electric machine controller is used for driving various motors and paper cutting portion, print head driver drives thermal printing head; I/O port connects various sensors.These sensors comprise temperature sensor and lid open-close condition checkout gear, and temperature sensor timing portion is connected.Open and-shut mode checkout gear, timing portion are also connected with cylinder device of rotation driving.Drum drive connects cylinder.
The utility model printer prevents cylinder deformation mechanism owing to being provided with, can be with predetermined time interval rotary drum a little, move termly the place being held down, and then in elimination printer because printer cover is pushed down the cylinder distortion that cylinder causes, further improve the print performance of printer.
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 amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
