Problems solved by technology

In this case, in the structure of Japanese Unexamined Patent Application Publication No. 2004-322538, there is a tendency that the pressure applied to the bearing member increases due to an increase in the weight of the carriage and an increase in the speed of movement of the carriage. As a result, the abutment part of the bearing member wears faster and the replacement frequency of the bearing member becomes higher

no. 1 Embodiment approach

[0030] figure 1 It is a schematic perspective view showing the overall configuration of the printing apparatus 100 . The printing device 100 is an inkjet printing device that performs printing by ejecting ink droplets from a print head, and is capable of printing and recording on a wide recording medium. In addition, the printing apparatus 100 is a printing apparatus of a serial scanning method that performs recording by repeatedly performing a conveying operation of a recording medium and a printing operation of ejecting ink droplets from the printing head as the carriage on which the printing head moves. . As the recording medium, recording paper, a plastic sheet, etc. can be used, and here, a case where recording is performed on the sheet 1 as continuous paper as the recording medium will be described.

[0031] Such as figure 1 As shown, the printing apparatus 100 includes a carriage 3 , a first guide member 4 (guide member), a second guide member 8 , a transport roller ...

no. 2 Embodiment approach

[0070] In the second embodiment, the structure of the bearing is different from that of the first embodiment. The other configurations are the same as those of the first embodiment, and thus description thereof will be omitted.

[0071] Figure 10 It is a perspective view showing the carriage 3 and the first guide member 4 . Such as Figure 10 As shown, bearings 29 are provided at both ends of the carriage 3 in the x direction. A bearing member 27 is arranged on each bearing 29 . The bearing member 27 located on one end side in the x direction is connected to the bearing member 27 located on the other end side by a link 30 .

[0072] Figure 11 is a cross-sectional view showing the carriage 3 and the first guide member 4, showing the Figure 10 The resulting state is viewed from the upstream side in the x-direction shown towards the downstream side. Such as Figure 11 As shown, the bearing 29 has two support portions 28 each supporting a bearing member 27 (contact pad)...

Abstract

The present invention provides a carriage device that suppresses the replacement frequency of parts of a bearing portion to enhance maintenance-free. The carriage device includes: a guide member; a carriage capable of reciprocating movement along the guide member; and a bearing member disposed on the carriage and tangent to the guide member, the carriage device also A mechanism for displacing the bearing member relative to the carriage is included, and the position of the bearing member tangent to the guide member is changed by the displacement.

Description

technical field [0001] The present invention relates to a carriage device that carries a printing head and the like and moves. Background technique [0002] In a printing apparatus, there is known a method of recording an image by applying ink to a medium by moving a carriage on which a printhead is mounted along a guide member and ejecting ink from the printhead. In such a printing device, a bearing for receiving the guide member is provided on the carriage, and the bearing and the guide shaft are brought into contact so that the carriage is supported by the guide member and the movement of the carriage is guided. [0003] In the image forming apparatus disclosed in Japanese Unexamined Patent Publication No. 2004-322538, a pair of replaceable bearing members are detachably attached to a support portion formed on a carriage to form a bearing. In this image forming apparatus, the pair of bearing members is arranged such that the included angle formed by the faces of the pair...
