[0081] see Figure 8 , a state detection device according to the third embodiment of the present invention includes:
[0082] The level value receiving unit 310 is used to obtain the first level value detected by the first receiving tube and the second level value detected by the second receiving tube;
[0083] The light receiving judging unit 320 is used for judging whether the first receiving tube and the second receiving tube receive the light emitted from the transmitting tube according to the first level value and the second level value;
[0084] The state judging unit 330 is used for judging the opening and closing state and the presence or absence of paper of the portable printer according to the light receiving conditions of the first receiving tube and the second receiving tube.

The invention discloses a portable printer, a state detection method, a device and a storage medium. The portable printer comprises a casing body, an upper casing cover, a controller and a photoelectric detection device. When the shell cover and the shell body are buckled together, a printing channel is formed on their mating surfaces; the photoelectric detection device comprises a transmitting tube, a first receiving tube and a second receiving tube, and the transmitting tube and the first receiving tube are located opposite to the printing channel The two sides of the transmitting tube and the second receiving tube are located on the same side of the printing channel; and the photoelectric detection device is configured so that the light emitted by the transmitting tube can be received by the first receiving tube and the light emitted by the transmitting tube can pass through the printing channel when it is buckled. The printed medium can be received by the second receiving tube after reflection. The present invention can simultaneously realize convenient opening and closing of the cover and detection of the presence or absence of paper on the premise of not bringing additional requirements on the overall volume and structural design.
Description
technical field [0001] The present invention relates to the technical field of printing, in particular to a portable printer, a state detection method, a device and a storage medium. Background technique [0002] Portable printers are favored by people because of their compactness, lightness, and easy portability. In a portable printer, paper is generally built into the printer, so judging the condition of the paper in the paper storage bin and the condition of the printer's opening and closing cover is a common and necessary function of the portable printer. [0003] At present, most of the portable printers on the market use photoelectric pairs to detect paper, and use mechanical switches to detect opening and closing covers, that is, the combination of mechanical switches and photoelectric pairs to complete the printer status identification detection. [0004] However, due to the limitation of the mechanical switch design, it is usually necessary to design a separate sp...
