Description

[Detailed Description of the Invention] The present invention relates to a recording device, and is a novel device that is lightweight, compact, and robust, and can be placed at any position on a recording medium to form a recorded image on the recording medium. This is what we provide.

Generally, a recording apparatus has a support base that supports a recording medium and a recording mechanism that forms a recorded image on the recording medium. For this reason, it is difficult to reduce the weight of the entire device, and a mechanism for fixing the recording medium is required. Furthermore, it is also difficult to form a recorded image on a portion of the recording medium that has an area larger than the area of the support.

The present invention solves these drawbacks, and includes a frame formed into a rectangular shape with a pair of parallel sides arranged orthogonally, and a frame that is attached to each side forming one of the pairs of parallel sides of the frame. a pair of parallel guide rails formed by a first guide rail, and a second pair of guide rails arranged orthogonally to the first guide rail, each having an end movably engaged with the first guide rail. The frame includes a guide rail and a recording head movably engaged with the second guide rail, the frame is placed over the recording medium with the recording head facing the recording medium, and the frame is positioned on the recording medium by the recording head. It is characterized by forming a recorded image on.

The drawings are configuration explanatory diagrams showing one embodiment of the present invention, in which 1 is a plan view and 2 is a sectional view taken along line A--A' of 1. In the drawings, 1 is a frame, 2 is a cover, 3 to 5 are guide rails, 6, 7
1 is a motor, 8 to 10 are carriages, 11 is a recording head, 12 and 13 are reeling yarns, and 14 to 25 are pulleys.

Frame 1 has parallel sides 1a, 1b and 1c
and 1d are orthogonally arranged to form a rectangular shape. The cover 2 is formed to cover a predetermined portion of the frame 1. The guide rails 3 and 4 are respectively attached so as to be parallel to sides 1c and 1d forming a pair of parallel sides. The guide rail 5 is disposed perpendicular to the guide rails 3 and 4, and one end is movably engaged with the guide rail 3 via a carriage 8, and the other end is movably engaged with the guide rail 4 via a carriage 9. engaged. A recording head 11 is movably engaged with the guide rail 5 via a carriage 10. The motor 6 moves the guide rail 5 in the X-axis direction via the reeling line 12, and the motor 7 moves the carriage 10 in the Y-axis direction via the reeling line 13.
It moves in the axial direction. These motors 6 and 7 are attached to the back surface of the frame 1 so that their rotating shafts protrude from the surface. Note that the drive circuits for these motors 6 and 7 may be installed within the frame 1, or may be placed separately and connected by cables. As the recording head 11, for example, a felt tip pen may be used. The reeling yarn 12 is
A portion is wound several times around the rotating shaft of the motor 6, one end is attached to the carriage 8 via a pulley 14, and the other end is attached to the carriage 8 via a pulley 15. Note that the pulleys 14 and 15 are attached near both ends of the side 1c of the frame 1. A part of the reeling yarn 13 is wound around the rotating shaft of the motor 7 several times, and one end is connected to the pulley 16 → pulley 17 →
It is attached to the pulley 20 via the pulley 18 → pulley 19, and the other end is attached to the pulley 25 via the pulley 21 → pulley 22 → pulley 23 → pulley 24. The pulleys 16 and 20 are attached near both ends of the side 1c of the frame 1, and the pulley 2
1 and 25 are attached near both ends of side 1d of frame 1, pulleys 17 and 19 are attached near both ends of carriage 8, pulleys 18 and 23 are attached near both ends of carriage 10, and pulley 2
2 and 24 are attached near both ends of the carriage 9.

When forming a recorded image on a recording medium (for example, recording paper) using the recording apparatus configured as described above, frame 1 is placed on the recording medium with the recording head 11 facing the recording medium. Deploy.
Thereby, a recorded image can be formed by the recording head 11 on the recording medium within the movement range of the recording head 11. Then, when recording at a predetermined location is completed, frame 1 may be moved to a desired location. By repeating such a procedure, a large recorded image can be formed by combining the partial recorded images on a recording medium having an area larger than the area formed by frame 1.

Since the device configured in this manner does not have a recording medium support, it can be made lighter and thinner. Also, because it has a frame structure,
It can be made solid.

Note that as the motors 6 and 7, pulse motors or servo motors are used. In particular, when a servo motor is used, the encoder can be installed at a remote location by using a reeling system, which is convenient because the degree of mechanical freedom in configuring the device is increased. Alternatively, a linear motor or a linear encoder may be used.

If the area of the recording medium is smaller than the rectangular area formed by frame 1, the recording medium may be fixed to the support member with adhesive tape, or a cutout window slightly smaller than the area of the recording medium may be formed to reduce the overall area. A holding member larger than the rectangular area formed by the frame 1 may be interposed between the frame 1 and the recording medium.

As explained above, according to the present invention, it is lightweight,
It is possible to realize a recording device that is compact, robust, and has excellent operability and mobility, which has great practical effects.
