Problems solved by technology

The existing protective structure is roughly realized from the outside of the printer and the overall structure of the self-service refueling equipment. The ability of the printer itself to prevent water, oil, and dust is very poor, especially the paper outlet of the printer. Gateway for moisture, oil, and dust to enter the printer

Embodiment Construction

[0019] Below in conjunction with the best embodiment shown in the accompanying drawings, it will be further described in detail.

[0020] The printer of the present invention can be vertically and submergedly installed on the operation panel of a self-service refueling device.

[0021] see figure 1 with figure 2 , the embodiment of the printer of the present invention generally includes: an upper case 1, a lower case 2, a printer main body 3, a baffle 5, a drive mechanism 7, a position detection switch 8 and a paper roll 9.

[0022] The lower end of the upper case 1 is provided with a pivot 11, and the middle part of the upper case 1 is provided with a nose 13 protruding outwards and extending obliquely from top to bottom. The lower end of part 13.

[0023] The lower case 2 has a cavity for accommodating the main body of the printer 3 and the paper roll 9. Pivot hole seats 21 are provided on both sides of the lower end, which can be matched with the pivot shaft 11 of the u...

Abstract

A printer comprises a housing and a printer body installed inside the same. The housing is provided with a paper exit. The printer further comprises a paper exit sealing mechanism installed in the housing. The paper exit sealing mechanism comprises a retainer plate and a drive mechanism, wherein the retainer plate is rotated to open or close the paper exit and the drive mechanism is controlled to drive the retainer plate. The printer with the paper exit well sealed is highly waterproof, oil-proof and dustproof.

Description

technical field [0001] The invention relates to a printer, in particular to a structure for waterproofing the printer against gas, oil and dust. Background technique [0002] Existing printers are generally designed for indoor application environments, or are arranged in a relatively independent container, for example: the ticket printer installed in the ATM teller machine, although the ATM teller machine itself is exposed to a certain extent, so that The printer needs to consider the environmental temperature tolerance, such as the high-temperature equatorial regions or the low-temperature polar regions. For the application of printers installed in self-service refueling equipment at gas stations, more environmental factors need to be considered, such as: water vapor, oil gas and dust. For this application, the existing countermeasures are generally realized by considering the overall structure of the self-service refueling equipment, such as: setting up a cabinet with a c...
