DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the configuration of the present invention will be described in detail with reference to the embodiments of the present invention shown in the accompanying drawings.
In FIG. 1, (2) is a casing of a lettering machine (4), and is configured in a shape suitable for mounting on a mounting surface such as a drawing board (5) or a desk. An elongated opening is formed in the front surface of the casing (2) along the X-axis direction.
[0006]
(6) is a recording tool support arm, and the tip end side projects horizontally from the opening to the front of the casing (2). The recording tool support arm (6) is translated in the X-axis direction along the opening of the casing (2) and is built in the casing (2) so as to be movable in the Y-axis direction. (Not shown). The recording tool support arm (6) is linked to an X motor (8) for movement in the X axis direction and a Y motor (10) for movement in the Y axis direction, which are built in the casing (2).
[0007]
(12) is an elevating plate which is supported by a tip end of the recording tool support arm (6) via a guide mechanism (not shown) so as to be movable up and down, and is hollow in the recording tool holding hole of the elevating plate (12). A holder portion of a recording tool (14) such as a pen, a pencil, or a ceramic pen is screwed so as to be detachable. The elevating plate (12) is linked to an actuator (16) such as a solenoid built in the casing (2) via a wire rope, and is configured to be driven in the elevating direction by the actuator (16). Yes.
[0008]
The lifting mechanism of the lifting plate (12) and the arm control mechanism for driving the recording tool support arm (6) in the XY axis direction are the same as the configuration disclosed in Japanese Utility Model Publication No. 3-14389. In addition, since these mechanisms are not the gist of the present invention, detailed description thereof is omitted. (18) is a visible light projector composed of a laser beam projector, and is positioned next to the recording tool (14) and fitted in the holding hole of the elevating plate (12) with the beam projection direction facing downward. Are held together.
[0009]
The light projector may use a light emitting diode or other light emitting element other than the visible laser beam. The XY motors (8) and (10), the actuator (16), and the light projector (18) are connected to a CPU (CPU) of a controller comprising a microcomputer built in the casing (2) via a driver for driving them. 20). The storage device (22) of the controller stores word processor program software, print drawing control program software, print drawing range display program software, and other program software including various symbols, graphics, and character pattern information.
[0010]
On the upper surface of the casing (2), an input device (32) comprising a liquid crystal display screen (26) of a display device (24), a character symbol input key (28), and a keyboard having various other keys (30). Is arranged. A ruler (34) is attached to the front surface of the casing (2).
Next, the operation based on the print drawing range display program software of the lettering machine will be described.
When the character / symbol input key (28) is operated to input print drawing information such as characters into the CPU (20), the input print drawing information is displayed on the screen (26).
[0011]
Next, when the print drawing range display key (34) is pressed, the support arm (6) is driven by the XY motors (8) and (10), on the outline imaginary line of the print drawing range (38) in front of the casing (2). The XY visible light projection position of the light projector (18) moves to a predetermined point (PO) (see FIG. 4). Next, the light projector (18) is turned on (light emission state) by the controller, and visible light projects a predetermined point (PO) in the print drawing range on the paper (36) in a spot shape. Next, the support arm (6) is driven in the X and Y directions by the controller, and the visible light from the light projector (18) is moved along the contour imaginary line of the print drawing range (38) (P1) (P2) ( P3) It moves in the order of (P0), and the print drawing range (38) of the lettering machine is visibly displayed on the paper (36) by visible light.
[0012]
If the print drawing information changes, and the print drawing range changes accordingly, the light rays correspond to, for example, the order of (P0) (P1 ′) (P2 ′) (P3 ′) (P0 ′). To move the print area to be displayed. The user corrects the position of the lettering machine on the paper (36) while confirming the print drawing range (38) on the paper (36) by the outline drawn with light rays, and then displays the print drawing range. Press the key (32) to turn off the print drawing range display operation. As a result, the contour line due to the light spot in the print drawing range (38) on the paper disappears.
[0013]
Next, when the print drawing start key (40) is pressed, the lettering machine shifts to the print drawing mode. When the print drawing mode is entered, the recording tool support arm (6) is controlled to move in the X and Y directions, and the lift plate (12) is controlled to move up and down, and the print drawing range (38) on the paper (36) is moved to a predetermined range. Input character information and the like are printed. In this embodiment, the light projector (18) is attached to the lifting plate (12). However, the present invention is not limited to the lifting plate (12), and the support arm (6) can be attached at an appropriate place. .
[0014]
【The invention's effect】
Since the present invention is configured as described above, the print drawing range on the paper can be visually recognized, so that characters and graphic patterns can be printed at a desired position on the paper. A printing mechanism display function can be added to the lettering machine with a simple mechanism.
