[0027] An embodiment of the present utility model provides a printer and a printing device applicable to detecting the remaining amount of printing paper in multiple scenarios. Among them, the printer applicable to detecting the remaining amount of printing paper in multiple scenarios includes a printer body 10; a paper bin 11 is provided on the printer body 10; one end of the paper bin 11 is provided with an opening 12; a paper bin cover 13 is provided at the opening 12; a paper outlet 111 and a paper shaft installation part 112 are provided inside the paper bin 11;
[0028] The first paper out detection sensor 113 is arranged around the paper shaft installation part 112;
[0029] On one side of the paper bin 11 far from the opening 12, a second paper out detection sensor 114 is provided, and on one side of the paper bin 11 far from the paper outlet 111, a third paper out detection sensor 115 is provided.
[0030] In specific implementation, such as Figure 1 , Figure 2 , Figure 3 shown, for a printer applicable to detecting the remaining amount of printing paper in multiple scenarios, it includes a printer body 10; a paper bin 11 is provided on the printer body 10; one end of the paper bin 11 has an opening 12; a paper bin cover 13 is provided at the opening 12; a paper outlet 111 and a paper shaft mounting part 112 are provided inside the paper bin 11; in this embodiment, the printer body 10, the paper bin 11, the opening 12, the paper bin cover 13, the paper outlet 111, the paper shaft mounting part 112, and the paper out detection sensor all adopt existing structures, which will not be elaborated herein again.
[0031] Such as Figure 1 shown, a first paper out detection sensor 113 is provided around the paper shaft mounting part 112; a second paper out detection sensor 114 is provided on one side of the paper bin 11 far from the opening 12, and a third paper out detection sensor 115 is provided on one side of the paper bin 11 far from the paper outlet 111.
[0032] Such as Figure 4 shown, when the user uses the paper shaft 15 and needs to feed paper upward (the paper feeding direction is as shown by the arrow); when the printing paper is about to run out, the remaining amount of the rolled paper 16 is detected by the first paper out detection sensor 113.
[0033] Such as Figure 5 shown, when the user does not use the paper shaft 15 and needs to feed paper upward (the paper feeding direction is as shown by the arrow); when the printing paper is about to run out, the remaining amount of the rolled paper 16 is detected by the second paper out detection sensor 114.
[0034] Such as Figure 6 shown, when the user uses the paper shaft 15 and needs to feed paper sideways (the paper feeding direction is as shown by the arrow); when the printing paper is about to run out, the remaining amount of the rolled paper 16 is detected by the first paper out detection sensor 113.
[0035] Such as Figure 7 shown, when the user does not use the paper shaft 15 and needs to feed paper sideways (the paper feeding direction is as shown by the arrow); when the printing paper is about to run out, the remaining amount of the rolled paper 16 is detected by the third paper out detection sensor 115.
[0036] The printer provided by the embodiment of the present utility model, which is applicable to detecting the remaining amount of printing paper in multiple scenarios, can meet the usage requirements of various usage scenarios such as different paper feeding directions and the presence or absence of the paper shaft 15.
[0037] In specific implementation, when two or less paper out detection sensors detect that the paper is about to run out, no prompt will be activated; when all three paper out detection sensors collect that the paper is about to run out, a reminder will be triggered.
[0038] In a specific implementation, sensors for detecting angles or positions can also be provided inside the printer body 10 to detect the installation state of the printer body 10. The printer body 10 can start corresponding paper end detection sensors for detection according to the detection results detected by the angle or position sensors, and turn off other paper end detection sensors.
[0039] Furthermore, the first paper end detection sensor 113, the second paper end detection sensor 114, and the third paper end detection sensor 115 are all provided on the same side wall.
[0040] In a specific implementation, the first paper end detection sensor 113, the second paper end detection sensor 114, and the third paper end detection sensor 115 are all provided on the same side wall. Being provided on the same side wall facilitates the subsequent arrangement of wires and circuit boards.
[0041] Furthermore, the circuit board 14 is V-shaped.
[0042] In a specific implementation, the first paper end detection sensor 113, the second paper end detection sensor 114, and the third paper end detection sensor 115 respectively pass through the side wall of the paper bin 11 and are connected to the circuit board 14 outside the paper bin 11; the circuit board 14 is V-shaped (as Figure 2 shown).
[0043] Furthermore, the second paper end detection sensor 114 is located directly below the paper shaft installation part 112; the third paper end detection sensor 115 is at the same horizontal position as the paper shaft installation part 112.
[0044] In a specific implementation, the second paper end detection sensor 114 is located directly below the paper shaft installation part 112; the third paper end detection sensor 115 is at the same horizontal position as the paper shaft installation part 112. The detection accuracy at the above positions is relatively high, and it can reduce the problems of false detection or inaccurate detection.
[0045] Furthermore, the first paper end detection sensor 113 is located at a position 30° - 60° obliquely upward from the paper shaft installation part 112.
[0046] Furthermore, the first paper end detection sensor 113 is located at a position 45° obliquely upward from the paper shaft installation part 112.
[0047] In a specific implementation, the first paper end detection sensor 113 is located at a position 30° - 60° obliquely upward from the paper shaft installation part 112; there are fewer printer components at this position, and it can reduce the interference with other components.
[0048] Optimally, the first paper end detection sensor 113 is located at a position 45° obliquely upward from the paper shaft installation part 112.
[0049] Furthermore, the first paper end detection sensor 113 is close to one side of the paper outlet 111 .
[0050] When implementing it, Figure 1 As shown, when in use, the diameters of the paper shaft installation cavities of the paper rolls 16 produced by different manufacturers and models are different, and usually the diameter of the paper shaft installation cavity is larger than the diameter of the paper shaft 15. In this embodiment, the first paper end detection sensor 113 is arranged on the side close to the paper outlet 111. The cooperation of this position and the above-mentioned angle can realize that when the paper shaft 15 is used, one first paper end detection sensor 113 detects the remaining amount of the paper roll 16 in two paper outlet states; and the detection accuracy is improved.
[0051] Furthermore, it also includes a hook 1121 and a protrusion 1122; the hook 1121 and the protrusion 1122 surround the paper shaft mounting portion 112 and form a notch on one side of the paper shaft mounting portion 112; a yielding portion 1123 is provided on one side of the hook 1121; the hook 1121 is deformable.
[0052] When implementing it, Figure 8 As shown, it also includes a hook 1121 and a protrusion 1122; the hook 1121 and the protrusion 1122 surround the paper shaft mounting portion 112 and form a notch on one side of the paper shaft mounting portion 112; a yielding portion 1123 is provided on one side of the hook 1121; the hook 1121 is deformable.
[0053] One end of the paper shaft 15 is provided with a clamping end 151 with a smaller diameter; and the diameter of the clamping end 151 is larger than the width of the notch;
[0054] During installation, the clamping end 151 of the paper shaft 15 is pressed against the notch. Since the hook 1121 can be deformed toward the side of the yielding portion 1123, the clamping end 151 can enter the paper shaft mounting portion 112. The clamping end 151 is limited in the paper shaft mounting portion 112 by the surrounding limiting of the hook 1121 and the protrusion 1122.
[0055] The paper shaft 15 is limited by the hook 1121, the protrusion 1122 and the yielding portion 1123 to prevent the paper shaft 15 from being offset when used in multiple scenarios and causing printing abnormalities.
[0056] The present invention also provides a printing device, which uses any of the above-described printers suitable for detecting the remaining amount of printing paper in multiple scenarios. The printing device is a self-service printer arranged horizontally or vertically.
[0057] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
