Description

Automatic cover opening device and printer using the automatic cover opening device

technical field

The utility model relates to a printer, in particular to a printer and an automatic cover opening device used in the printer.

Background technique

FIG. 1A is an exploded view of a conventional cover opening device, FIG. 1B is a schematic cross-sectional view of the assembly of the cover opening device of FIG. 1A , and FIG. 1C is a schematic view of applying the cover opening device to a printer. Please refer to FIG. 1A , FIG. 1B and FIG. 1C at the same time. In the existing cap opening device 100 , a compression spring 120 is installed in the bracket 110 , and the spring force of the compression spring 120 provides the pushing force of the sleeve 130 . The cam cover 140 is locked on the upper cover 210. After the upper cover 210 is turned up, it will be turned back with the thrust of the sleeve 130. The baffle plate 150 installed at the rear will block the cam cover 140 at a fixed angle, so that the upper cover can be opened 210 for the purpose of replacing the ink cartridge.

Although this design can achieve a large supporting force, relatively speaking, a user needs a relatively large force to turn up the upper cover 210 . Therefore, it is not easy to lift the upper cover 210 for persons who are weak in strength such as the elderly and children. Moreover, when the upper cover 210 is to be closed, there is no buffer device when the upper cover 210 falls, which may easily cause pinching.

There is another kind of switch that uses a motor to cooperate with a rack to drive the upper cover. However, the rack is mostly made of plastic, and the friction between the plastics tends to generate a lot of noise.
