[0006]

A conventional XY recorder that records a plurality of signals is a Y-block for each block as described above.
A bar section is formed, and a plurality of Y bars are connected to form one recording section. As described above, since the Y-axis motors, which are relatively large components, must be arranged adjacent to each other, the size of the Y bar in the X direction becomes very large, and as a result, compared to the size of the recording apparatus. As a result, the recording range is narrowed, and in order to widen the recording range, the size of the recording apparatus itself must be increased.

In the case where the driving force is transmitted to one side of the Y-bar and the other side moves following it as shown in FIG.
There has been a problem that the side of the Y-bar section that does not transmit the driving force cannot accurately follow the driving section side due to a force such as an inertia force. Therefore, conventionally, a Y-axis driving unit mounting portion 33, a driving pulley 35, a tension pulley 36, a wire 37, and a guide shaft 32 are provided on both ends of the Y-bar, and the driving force of the X-axis motor 31 is applied to both ends of the Y-bar via a shaft. The above-mentioned problem has been solved by transmitting the driving force to the drive pulleys 35 on the respective sides. However, in the conventional apparatus, since the heavy Y motor is attached to one side of the Y bar, the weight balance of the Y bar is uneven, and the driving force is transmitted to both ends of the Y bar. In this case, too, a large load is applied to one of the driving pulleys, causing a problem that stable high-speed and high-acceleration recording cannot be performed.
The present invention has been made to solve these disadvantages, and an object of the present invention is to provide a recording apparatus having a good weight balance and capable of performing stable high-speed recording.

[0008]

In order to achieve the above object, a pen block sliding mechanism of a recording apparatus according to the present invention is provided.
Two pen blocks can slide along one sliding bar
Configured.

[0009]

In the pen mechanism of the recording apparatus according to the present invention, the sliding bar is formed by a single member.
By minimizing the size of the recording block sliding mechanism and arranging the pen block driving means alternately in the longitudinal direction of the sliding bar, the sliding bar can be driven smoothly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A pen block sliding mechanism of a recording apparatus according to the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of a pen block sliding mechanism of a two-channel XY recorder according to the present invention, and FIG. 2 is a Y bar in which a second upright plate 413 of a slide bar 41 is cut and a pen block portion is omitted. FIG. 4 is a perspective view of a unit 4, in which the same or equivalent components as those of the conventional recording apparatus are denoted by the same reference numerals. In the figure, reference numeral 41 denotes a U-shaped sliding bar formed by opening the upper portion, 42 denotes a carriage movable by rollers 46 along a groove provided inside the sliding bar 41, and 45 denotes a carriage. A pen arm 34 holding the recording pen 5 and engaged with the carriage 42 is a Y-axis drive motor for driving the carriage 42, the pen arm 45 and the recording pen 5, and the one-channel drive motor 341 and the two-channel drive motor 342 The Y-axis drive belts 441 and 442 are provided at the end portions of the slide bar 41 so as to face each other and tension pulleys provided at the ends of the slide bars facing the respective drive motors.
Is wound. Further, similarly to the conventional recording apparatus, the slide bar 41 is moved by the X-axis drive motor 31 through the Y-axis drive unit 33 and the X guide shaft 32 (not shown) provided at both ends of the slide bar 41 in the X direction. It is configured to be movable.

As shown in the drawing, the pen block sliding mechanism for one channel uses a driving motor 341 for one channel and a driving pulley 343 for one channel to move the X of the sliding bar 41.
It is arranged on the flat plate 411 on the side (−Y) provided with the shaft driving mechanism,
A one-channel tension pulley 345 is disposed on the end side of the opposing slide bar 41, and a one-channel drive belt 441 is wound around each pulley. Also,
The one-channel pen carriage 421 is engaged with the driving belt 441 and is moved along the grooves provided on the flat plate 411 and the first top plate 414 by rollers 46 rotatably provided on the upper and lower parts of the carriage. It is configured to be movable.

In addition, the pen block sliding mechanism for two channels includes a two-channel driving motor 342 and a two-channel driving pulley 344, and a flat plate 411 on the + Y direction side of the sliding bar 41, that is, a one-channel tension pulley 345. The sliding bar 41 is disposed at a location adjacent to the
, The two-channel tension pulley 346 is disposed at a position adjacent to the one-channel drive pulley 343, and the two-channel drive belt 4 is attached to each pulley.
42 is wound. Further, the pen carriage 422 for two channels is locked by the drive belt 442 and
Like the channel pen carriage 421, the roller 46
Thus, the carriage 411 is configured to be movable along a groove provided in a flat plate 411 and a second top plate 415 rotatably provided at an upper portion and a lower portion of the carriage. Therefore, these two
Carriages 421 and 422 are each independently provided with a sliding bar 4
1 is provided movably.

The main body of the Y-axis drive motor is generally much larger than the drive pulley. If two drive motors are provided adjacent to each other, the width of the slide bar in the X direction increases, and the slide bar slides. Although the moving bar itself becomes large, the width of the sliding bar in the X direction can be reduced by arranging the driving motors for the respective channels in opposition alternately as in the above-described configuration. .

This pen block sliding mechanism moves in the X-axis direction based on a recording signal. As described above, by arranging heavy driving motors alternately in opposition, the longitudinal length of the sliding bar is increased. In the direction (Y direction), the weight is balanced, and the movement in the X axis direction can be performed stably.

[0015]

As described in detail above, according to the pen block sliding mechanism of the recording apparatus of the present invention, the sliding bar can be formed narrow in the moving direction, thereby reducing the size of the recording apparatus. or recording range can be widened to, by reducing the number of parts of the sliding mechanism simultaneously Sosu the effect that it is possible to configure the drive mechanism at low cost and lightweight
You.
