Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a writing brush printer having flexibility in three axial directions of X direction, Y direction, and Z direction and capable of stepless displacement in each direction. Is.

(Prior Art) When writing with a writing brush, generally, the writing brush is arranged vertically with respect to the paper surface, and this writing brush is placed in the left, right, front, back, up, and down directions, that is,
The brushes are moved simultaneously in the three axis directions of X, Y, and Z, but at this time, it is extremely difficult to hold the brush in a vertical state.

Therefore, in a sense, it is possible to write characters that have individual differences or tastes, but at the same time, this is one of the factors that make the writing of people who are unfamiliar with writing brush poor. On the other hand, in a brush printer capable of mechanically holding a brush, it is extremely easy to always hold the brush vertically to the paper surface.

By the way, when writing with a brush, it is important to start writing, that is, the contact between the tip of the brush and the paper.

Consider, for example, the case where a person writes the characters in a regular typeface with a brush. First, the X and Y coordinates of the writing start are determined on the paper surface, and the tip of the brush touches the paper surface just before the tip touches the paper surface. It is common to drive the tip of the ear into the paper while moving in the X-, Y-, and Z-axis directions at the same time in the right downward direction.

In a conventional brush printer, a three-dimensional scanner is configured by mounting a moving mechanism in the Z (up and down) direction on a carrier that can move in the X (left and right) and Y (back and forth) directions.

(Problems to be solved by the device) However, in the brush printer configured as described above, as shown in FIG. 6 (A), the brush shaft 1 held in the vertical direction is moved in the X direction or the Y direction. If the hammer is not moved at the same time, but is moved only in the Z direction, as shown in FIG. 6 (B), the tip 1a will buckle and crack, so that the hammer cannot be driven well. As a result, there is a problem that it is impossible to write beautiful brush letters and powerful thick letters.

In other words, even if the gestures that people are doing easily
If done mechanically, it is necessary to express the program as a character font even in the movement in the space before writing a character. Therefore, in the case of the conventional brush printer, it is necessary to move the scanner in the X, Y, and Z directions at the same time. There was a problem that the control program and font program became complicated.

SUMMARY OF THE INVENTION An object of the present invention is to provide a brush printer capable of smoothly writing a brush with simple font data and beautifully drawing a black mark, particularly a black mark at the beginning of writing.

(Means for Solving the Problems) Therefore, in the brush printer of the present invention, a unit for supporting the brush is provided so as to be movable in the X, Y, and Z directions with respect to the paper surface, and the characters are recorded based on the font data. In the writing brush printer, the first moving means for moving the unit in the X direction and the Y direction with respect to the paper surface, and the unit at least in the X direction and the Z direction when starting recording on the paper surface with the brush. At the same time, or a second moving means for moving simultaneously with the Y direction and the Z direction is provided.

(Operation) The unit for supporting the brush is moved in the direction closer to the paper surface by the second moving means for moving the unit at least in the X direction and the Z direction or in the Y direction and the Z direction at the same time to start recording. Therefore, the brush is driven diagonally to the paper surface.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 show a first embodiment of the present invention, in which a brush printer body 2 having a hollow frame shape is divided into an upper body frame 3 and a lower body frame 4, and a lower body. The upper body frame 3 is superposed on the frame 4 so as to be able to move up and down.

A guide 6 that is movable in the X direction (left and right direction in FIG. 2) along the upper body frame 3 is provided in the middle portion 5 formed in the center of the brush printer body 2.
A carrier 7 that is movable in the Y direction (vertical direction in FIG. 2) along with a holder 8 that is attached to the carrier 7 so as to hold the brush shaft 1 vertically on a paper surface 9. A scanner 10 that operates as a so-called XY recorder is installed. The scanner 10 is moved in the XY directions by a driving device (not shown) as a moving means.

On the lower surface of the lower body frame 4, the brush printer body 2
Feet 11 that support the whole at three points are provided.

Male screw studs 12 having fine pitch screws are vertically installed at the four corners of the upper body frame 3, and fine pitches are formed at the four corners of the lower body frame 4 corresponding to the male screw studs 12. Female threaded stud 13
Are erected concentrically with the male screw stud 12 maintaining a required clearance.

Between each female screw 13 and the male screw 12, a threaded pulley 15 provided with a screw portion 14 that is screwed to both of them at the same time.
Are arranged, and the toothed belt 16 is wound around the pulley 15.

The toothed belt 16 is driven by a driving device (not shown) serving as a moving unit to rotate each pulley 15 at the same time,
Upper body frame 3 through lifting and lowering of male screw stud 12
Is movable in the Z direction (vertical direction in FIG. 1) with respect to the lower body frame 4.

If the brush shaft 1 is held by the holder 8 of the scanner 10 perpendicularly to the paper surface 9 and the toothed belt 16 is driven to simultaneously rotate the threaded pulley 15, the pulley 15 will be threaded internally. The male screw stud 12 is raised and lowered by screwing the male stud 12, and the male screw stud 12 is screwed by the pulley 15, so that the upper body frame 3 is raised and lowered with respect to the lower body frame 4. This makes the brush axis 1
Is driven in the Z direction by driving the scanner 10 separately from the X and Y directions.

Accordingly, the upper body frame 3 is lowered from the position indicated by the chain double-dashed line in FIG.
When 0 is moved in the X and Y directions, the tip 1a of the brush shaft 1 becomes
It is driven into the paper surface 9 smoothly without cracks shown in FIG. 6 (B).

That is, the writing of the so-called "Atama" portion at the beginning of writing a brush character is performed extremely smoothly. further,
By moving the scanner 10 in the X and Y directions in this state, powerful thick letters are drawn and the ink marks are also beautiful.

Since the movement of the brush shaft 1 in the Z direction in the above-described embodiment is performed separately from the movement in the Z and Y directions by the scanner 10, all movements in the X, Y, and Z directions are performed by the scanner 10. The control program and the font program can be simplified and simplified, and the writing speed can be increased, as compared with the case of performing it.

Further, by separating the moving mechanism in the Z direction from the scanner 10, the structure of the scanner 10, in particular, the structure of the carrier 7 can be simplified, so that the scanner 10 can be made robust.

Next, FIGS. 3 and 4 show another embodiment of the present invention in which the Z-direction moving mechanism and the function of the foot 11 in the first embodiment are combined. .

That is, the brush printer main body 2 which has been divided into the upper and lower parts has an integrated structure, and the shaft 22 is tilted at a front left / right position and a rear central position in the main body 2 in this embodiment with a horizontal inclination of about 30 °. And the sector gear 17 is attached to each shaft 22, and the bottom surface of the brush printer main body 2 is rotatably passed through one end of the gear 17 about the shaft 22 and extends toward the paper surface 9 side. Foot 18
And the drive gear 19 for rotating the foot portion 18 meshes with the sector gear 17 to form a moving means.

In such a configuration, when the drive gear 19 is rotated to rotate the sector gear 17 about the shaft 22,
The foot portion 18 rotates together with the gear 17. At this time, foot 1
Since 8 is in contact with the paper surface 9, the shaft 22 side is relatively displaced upward, and the brush printer main body 2 is moved up and down. At this time, since the shaft 22 is inclined with respect to the horizontal direction, the brush printer main body 2 moves in the Z direction and moves in the X,
It can be moved in the Y direction.

That is, as the foot portion 18 moves up and down in the Z direction, the brush shaft 1 is also moved in the X and Y directions, so that the brush can be smoothly inserted.

Therefore, as shown in FIG. 5, even with a simple skeleton character font 20 that is a simple quadrangle in the X and Y directions, a beautiful brush character 21 can be obtained by adding vertical movement in the Z direction.
Can be drawn.

It should be noted that the present invention is not limited to the above-described embodiments, and it goes without saying that various modifications can be made without departing from the scope of the present invention.

(Effects of the Invention) According to the writing brush printer of the present invention, in a writing brush printer that has a unit that supports a writing brush in the X direction, the Y direction, and the Z direction with respect to the paper surface and records characters based on font data. , The unit in the X direction with respect to the paper surface,
A first moving means for moving in the Y direction, and a first moving means for moving the unit at least simultaneously in the X and Z directions or at the same time in the Y and Z directions when recording on the paper surface with the brush. Since the unit is moved in the direction approaching the paper surface by the second moving means to start recording, the brush is driven obliquely with respect to the paper surface, so that simple font data can be obtained. With this, it is possible to smoothly insert a brush, and it is possible to draw beautifully the ink marks, especially the ink marks at the beginning of writing.
