  The two-tiered printer described in Patent Document 2 can prevent the lower printer from overturning when the lower printer body is pulled out, but the upper printer housing is used as the lower housing. On the other hand, since it is necessary to shift to the rear side, there is a problem that a large installation space for two printers is required. Further, when the upper printer body is pulled out, the upper printer may be inclined due to the movement of the center of gravity toward the front side.

  Therefore, an object of the present invention is to provide a pull-out type printer that can install the same printer in a plurality of upper and lower stages in a narrow installation space, and can prevent the uppermost printer from tilting or overturning. is there.

  In order to solve the above-mentioned problems, the present invention mounts a printer main body housed in a casing on a moving base that moves in the front-rear direction of the casing, and the moving base on which the printer main body is mounted is mounted on the casing. In the printer that can be pulled out to the front side, a configuration is adopted in which the amount of pulling of the moving base toward the front side can be set in a plurality of stages.

  In other words, by making it possible to set the pull-out amount to the front side of the moving base equipped with the printer main unit in multiple stages, the same printer can be installed in multiple upper and lower stages without shifting the casing back and forth. Set the pull-out amount of the printer's moving base smaller than that on the lower side to reduce the movement of the center of gravity to the near side, and the same printer can be installed in multiple upper and lower stages in a narrow installation space. The upper printer can now be prevented from tilting or falling over.

  By allowing the front part of the ceiling of the casing to be opened, the front part of the ceiling of the casing can be opened and consumed even for the uppermost printer where the amount of drawer of the printer main body is reduced. Product replacement and maintenance can be performed easily.

  In the printer according to the present invention, it is possible to set the pull-out amount to the front side of the moving base equipped with the printer main body in a plurality of stages, so that the same printer is installed in multiple upper and lower stages without shifting the casing back and forth. In addition, the upper printer's moving base can be pulled out less than the lower printer's, and the center of gravity can be moved to the near side. In addition, it is possible to prevent the uppermost printer from being inclined or overturned.
