Patent Application
20120308287
1. Technical Field
The present disclosure relates to moving apparatuses, more particularly, to a moving apparatus used in a printer.
2. Description of Related Art
A printer may include a printing module with a print head and a moving module for driving the printing module across the paper to be printed. The print head of the printing module should be capable of fluent and stable movement to assure printing quality. Usually, the printing module slides on a shaft which is mounted on the printer. When the shaft is in use for a long period of time, it may become a loose fit in the printer module, which may cause faltering in the printing module.
Therefore, there is room for improvement within the art.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to
The support board 10 includes a bottom wall 101 and a side wall 103. A first edge of the bottom wall 101 is connected to an “n”-section sliding pole 15. The side wall 103 is perpendicularly connected to a second edge of the bottom wall 101. The second edge is opposite to the first edge. The sliding pole 15 includes a connecting piece 151, a first bent piece 152, and a second bent piece 153. The connecting piece 151 is perpendicularly connected to the first edge of the side wall 103. The first bent piece 152 is perpendicularly connected between the connecting piece 151 and the second bent piece 153. The second bent piece 153 is parallel to the connecting piece 151. The bottom wall 101 defines a through hole 12 adjacent to a first end of the sliding pole 15. A follower wheel 18 is mounted on the bottom wall 101 adjacent to a second end of the sliding pole 15. A plurality of securing pins 105 are mounted on the side wall 103.
The restricting piece 30 includes a upright securing portion 31 and a horizontal restricting portion 32. The securing portion 31 defines a plurality of securing holes 311 corresponding to the plurality of securing pins 105 of the side wall 103.
A motor 40 can be mounted on the bottom wall 101. The motor 40 includes a drive wheel 41. The motor 40 can drive the drive wheel 41 to rotate.
A belt 42 can be set on the drive wheel 41 and the follower wheel 18. The drive wheel 41 rotates to move the belt 42, and the follower wheel 18 is rotated accordingly.
The printing module 50 defines a sliding groove 51 at a bottom portion thereof.
Referring to
In succession, the plurality of securing pins 105 is inserted in the plurality of securing holes 311 to mount the restricting piece 30 onto the support board 10. The restricting portion 32 of the restricting piece 30 is located above the bottom wall 101. Then, the printing module 50 is placed on the support board 10 with the sliding pole 15 located in the sliding groove 51. The printing module 50 is freely slidable on the sliding pole 15. Simultaneously, the printing module 50 is attached to the belt 42 at one point and may be moved by the belt 42. The restricting portion 32 and the bottom wall 101 restrict between them a portion of the printing module 50.
In use, the motor 40 rotates the drive wheel 41 to move the belt 42 so as to slide the printing module 50 on the sliding pole 15.
In the moving apparatus, the sliding pole 15 is integrally formed on the support board 10 and the sliding pole 15 may not come loose from the support board 10. The greater surface area of the sliding pole 15 (compared to the smaller surface area of a round rod or shaft), the greater precision for the print head and a longer service life.
It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
