printer

Abstract

The present invention provides a printer. The printer is a simple structure, and can be accurately printed, and the printer includes a frame, the printer frame member can be easily assembled. The printer (1) includes a printer with the printer frame constituting member (31), the printer frame (31) is provided with an undercarriage (32) and a printer body frame (33) mounted to the chassis (32), the printer body frame (33) includes a first frame, a second frame and a third frame (34,35,36). A carriage guide shaft (22) is to be erected in the first frame (34), and the carriage guide shaft (22) to guide the carrier print head (20) of the head carriage (21), in the second frame (35) and the third frame (36), a recording paper storage portion (11) and is configured for accommodating the recording paper (10).

Description

technical field [0001] The present invention relates to an improvement of a printer frame made of sheet metal for a printer. Background technique [0002] In a serial printer, printing is performed on recording paper drawn from a recording paper roll stored in a recording paper storage unit by a print head mounted on a head carriage that reciprocates along a carriage guide shaft. In such a printer, a printer made of a metal plate includes a printer mechanism unit configured to mount printer components, and the printer mechanism unit is covered by a plastic printer case. [0003] Patent Documents 1 and 2 disclose a printer including a printer frame having such a structure. In the printer disclosed in the above-mentioned document, the opening and closing frame is attached to the printer frame. When the opening and closing frame is opened, the recording paper storage section for storing the recording paper roll is opened, and the recording paper storage section passes through ...

AI Technical Summary

Problems solved by technology

Therefore, the printer frame as a whole has a complicated structure, and it is not easy to ensure the dimensional accuracy of each part, and the structure of the metal mold used to press the printer frame has to be complicated.

In addition, when assembling the components of the printer to the main frame of the printer, for example, it is necessary to expand the left and right side plate parts to install the components, and the assemblability may also be poor.

In addition, if cuts and the like for assembling various printer components are formed, there is a possibility that the mechanical strength such as the bending strength of the printer frame and the rigidity of each part thereof will also decrease.
