Image forming apparatus

Abstract

The invention provides an image forming apparatus which can easily assemble and unassemble a guide component of a print cartridge without multifarious operation or enough space of machine width direction. The image forming apparatus includes a carriage (4), an image forming unit (11) installed in the carriage (4) to eject liquid onto a recording medium, a guide member (3) to guide the carriage (4) in a main scanning direction corresponding to a width direction of the recording medium, and a position restriction member (85) detachably attachable to the carriage (4) to restrict a position of the carriage (4) relative to the guide member (3) in a vertical direction. The carriage (4) includes a first slide member (57) slidably supported by the guide member (3), a second slide member (59) that slidably contacts the guide member (3) to prevent rotation of the carriage (4) relative to the guide member (3), and a third slide member (61) that slidably contacts the guide member (3) to determine a position of the carriage (4) in a sub-scanning direction perpendicular to the main scanning direction. The position of the carriage (4) is not restricted by the guide member (3) in the vertical direction.

Description

technical field [0001] The present invention relates to the use of paper (not limited to paper, but also OHP, etc.) after ink is discharged from the recording nozzle mounted in the print cartridge, which refers to ink droplets or other liquids that can adhere, also known as the recording medium , recording medium, recording paper or recording paper, etc.) An inkjet image forming device that forms an image. Background technique [0002] Conventionally, in an inkjet printer having a mechanism for reciprocating a print cartridge equipped with a recording head in the width direction of the paper along a guide member (guide rod, guide rail), the print head was exchanged due to a failure of the recording head or the like. When removing the print cartridge, it is necessary to pull out the print cartridge from the guide member in the paper width direction. This operation is relatively complicated, not only the print cartridge that needs to be removed, but also takes time because ma...

AI Technical Summary

Problems solved by technology

Therefore, when exchanging the print cartridge, many parts need to be removed before removing the print cartridge, and the operation is complicated (Patent Document 1)

In addition, especially regarding the installation space, the problem of bad operability at the time of cartridge replacement has not been solved because there is not enough space in the width direction of the machine
