Fig. 1 shows the structure diagram of thermal printer.As shown in Figure 1, thermal printer mainly includes printer body
1st, paper roll 2, be arranged in printer body 1 be used for place paper roll 2 and allow paper roll 2 freely to turn within the specific limits in it
Dynamic incorporating section 3 and the sheet cutter (not shown) for cutting off label paper.With reference to the orientation in Fig. 1, such as in incorporating section 3
Front side and rear side between be provided with shaft, shaft is through paper roll 2, and the internal diameter of paper roll 2 is more than the outside diameter of shaft, so
It can allow the freely activity in certain scope of paper roll 2.Wherein, opposed platen roller is provided with printer body 1
And thermal printing head, in print procedure, the rotation of platen roller makes the label paper of stretching paper roll be conveyed along paper delivery direction, together
When, by thermal printing head to just being pushed in rotating platen roller, so as to complete the print job to label paper.Usually receive
Receive portion 3 be configured with can detect paper roll outside diameter whether be less than preset value sensory package, specifically, detecting paper roll
When outside diameter is less than preset value, then the testing result can be based on by corresponding executive component to speaking and/or light alerting signal,
Remind user to replace paper roll in time, avoid the idle running of printer.In the utility model, sensory package is in a movable manner
It is arranged at incorporating section 3.
Fig. 2 shows a kind of track of thermal printer of the utility model and the assembling schematic diagram of sensory package, and Fig. 3 shows this
A kind of track of thermal printer of utility model and the exploded perspective view of sensory package.As shown in Figures 2 and 3, in incorporating section 3
Outside (side away from paper roll 2) is provided with track 31, and the outer rim of track 31, which extends internally, can make sensory package 32 in cunning
The enclosing structure of track 31 is not departed from dynamic process, if enclosing structure can be the circumferentially distributed both sides outer rim in track 31
It is multiple inwardly bendings enclosing piece 311.Preferably, track 31 is a part for loop configuration, such as by loop configuration
Position limiting structure is provided with, enables sensory package 32 free to slide within the specific limits.Specifically, with reference in Fig. 2
Orientation, is provided with the baffle 312 of horizontal direction on the right side of loop configuration, and upper left 31 width of track is configured to pass
The tight fit of 32 holding of component is felt, so that sensory package 32 can only be free to slide in the arc range of about pi/2.
It will be appreciated by persons skilled in the art that can be according to practical situation, corresponding with the axial both ends of paper roll 2
The either side of incorporating section 3 or both sides are both provided with above-mentioned track 31 and sensory package 32.The specific location and knot of position limiting structure
Structure can also be adjusted flexibly according to practical situation, as long as can ensure that sensory package 32 is determined by track 31 and position limiting structure
In the range of it is free to slide.It may be replaced by installing in the corresponding positions of the lid structure of printer body 1 as being fitted close
Convex block is equipped with, in the case of covering, relevant position of the convex block just at track 31.
With further reference to Fig. 2 and Fig. 3, along the end on observation of paper roll 2, the non-bulging incorporating section 3 of enclosing piece 311.And background skill
In the scheme for the increase knob mentioned in art, the mode that knob generally requires to be arranged to protrude printer is with convenient to operate.It can see
Go out, the utility model improves the planarization of thermal printer.
With continued reference to Fig. 3, sensory package 32 include can be free to slide in orbit housing 321 and be fixed on housing
Sensor 322 in 321, it is preferable that sensor 322 is photoelectric sensor, accordingly, thermal printing is provided with track 31
The corresponding multiple loopholes 313 (such as two) of placement status of machine, so that photoelectric sensor can be detected by loophole 313
Whether the outside diameter of paper roll 2 is already less than preset value.Specifically, in the case of the outside diameter of paper roll 2 is less than preset value, incorporating section
Light inside 3 is pointed into track 31 by loophole 313, in the case of the probe of photoelectric sensor detects optical signal, you can
User is reminded to replace paper roll 2 by corresponding executive component, such as in the case of the probe of photoelectric sensor detects optical signal,
User is notified to replace paper roll 2 by way of sound and/or light are reminded.
Fig. 4 A show a kind of placement status schematic diagram one of thermal printer of the utility model, and Fig. 4 B show the utility model
A kind of placement status schematic diagram two of thermal printer.Below the thermal printing of the utility model is illustrated to combine Fig. 4 A and 4B
In machine, whether the outside diameter that sensory package 32 can detect paper roll 2 when thermal printer is in a variety of placement statuses is less than in advance
If the principle and process of value.
As shown in Figure 4 A, in the case of thermal printer is horizontal positioned, sensory package is tied under the action of self gravitation
The setting of position limiting structure is closed, rests on the leftward position for the track (back side in figure) being arranged on incorporating section 3, in detection paper roll
Outside diameter when being less than preset value, light that the loophole 313 in the i.e. detectable left side of probe of photoelectric sensor is come in (herein it
Preceding light is blocked by paper roll).
As shown in Figure 4 B, in the case of thermal printer is changed into placing (rotating clockwise 90 °) vertically, sensory package exists
The setting of position limiting structure is combined under the action of self gravitation, rests on the track (back side in figure) that is arranged on incorporating section 3
Right positions, when the outside diameter for detecting paper roll is less than preset value, the loophole in the i.e. detectable left side of probe of photoelectric sensor
313 light come in.
As can be seen that in the utility model, it is free to slide in track 31 by sensory package 32, work as thermal printing
When machine is in two kinds of placement statuses, intervention without human intervention, the outside diameter that sensory package 32 can reliably detect paper roll 2 is
It is no to be less than preset value.In addition, the utility model also have the advantages that it is simple in structure, ingenious in design.
It should be noted that although describe temperature-sensitive using label paper roll, two kinds of placement statuses are substantially vertical as example and beat
Print machine as above, it is understood by one of ordinary skill in the art that the present invention answers not limited to this.In fact, user completely can be according to product
The situation such as demand and practical application scene flexibly sets the concrete form of printer, as being non-perpendicular between two kinds of placement statuses
Relation, paper roll are common temperature-sensitive paper roll of non-label paper etc..
So far, the preferred embodiment shown in the drawings technical solution that the invention has been described, still, this area are had been combined
Technical staff is it is easily understood that the above is only the preferred embodiment of the utility model only, not limiting this reality
With new, where within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on, should all include
Within the scope of protection of the utility model.
