[Problems to be solved by the device]

 A conventional XY recorder for recording a plurality of signals is configured to form a Y bar section for each block as described above and to connect these plurality of Y bars to form one recording section. . In this way, since the Y-axis motors, which are relatively large parts, must be placed next to each other, the size of the Y bar in the X direction becomes extremely large, which is larger than the size of the recording device. As a result, the recording range became narrower, and there was the problem that the recording device itself had to be enlarged in order to expand the recording range.

Further, as shown in FIG. 4A, when the driving force is transmitted to one side of the Y bar and the other side moves following it, when recording at high speed and high acceleration, There has been a problem that the side of the Y-bar that does not transmit the driving force cannot accurately follow the side of the driving unit due to force such as inertial force. Therefore, conventionally, a Y-axis drive portion mounting portion 33, a drive 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 transmitted via the shaft to the Y-bar. By transmitting to the drive pulleys 35 on both end sides, the above-mentioned problem has been solved. However, in the conventional device, since the heavy Y motor is attached to one side of the Y bar, the weight balance of the Y bar part is unbalanced and the driving force is transmitted to both ends of the Y bar part. Even in this case, a large load is applied to the drive pulley on one side, which causes a problem that stable high-speed and high-acceleration recording cannot be performed. The present invention has been made to solve these drawbacks, and an object of the present invention is to provide a recording apparatus having good weight balance and capable of stable high-speed recording.

[0008]

[Means for Solving the Problems]

 To achieve the above object, a pen block sliding mechanism of a recording apparatus according to the present invention comprises a plurality of pen blocks slidable along one sliding bar, and a pen block driving means. It was constructed by alternately arranging both ends of the sliding bar.

[0009]

[Action]

 In the pen block sliding mechanism of the recording apparatus of the present invention, the size of the recording block sliding mechanism is minimized by forming the sliding bar with a single member, and the pen block driving means is used as the sliding bar. By alternately arranging them in the longitudinal direction, the sliding bar can be driven smoothly.

【Example】

The pen block sliding mechanism of the recording apparatus of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-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 block diagram in which the second upright plate 413 of the sliding bar 41 is cut to omit the pen block portion. It is a perspective view of the bar portion 4, and in the figure, the same or equivalent configurations as those of the conventional recording apparatus are denoted by the same reference numerals. In the figure, 41 is a U-shaped sliding bar formed by opening the upper part, 42 is a carriage configured to be movable by a roller 46 along a groove provided inside the sliding bar 41, and 45 is a carriage. A pen arm that holds the recording pen 5 and is engaged with the carriage 42 is a Y-axis drive motor that drives the carriage 42, the pen arm 45, and the recording pen 5, and is a 1-channel drive motor 341 and a 2-channel drive motor 342. Are arranged so as to face each other at the end portions of the sliding bar 41, and the Y-axis drive belts 441 and 442 are wound around the tension pulleys provided at the end portions of the sliding bar facing the respective drive motors. Is configured. Further, the sliding bar 41 is driven by the X-axis driving motor 31 via the Y-axis driving section 33 and the X guide shaft 32 (not shown) provided at both ends of the sliding bar 41, as in the conventional recording apparatus. It is configured to be movable in the X direction.

As shown in the drawing, the pen block sliding mechanism for one channel includes a driving motor 341 for one channel and a driving pulley 343 for one channel on the side where the X-axis driving mechanism of the sliding bar 41 is provided. 1-channel tension pulley 345 is arranged on the end side of opposing sliding bar 41, and 1-channel drive belt 441 is wound around each pulley. It The 1-channel pen carriage 421 is locked to the drive belt 441, and is inserted into the grooves provided on the flat plate 411 and the first top plate 414 by the rollers 46 rotatably provided on the upper and lower portions of the carriage. It is configured to be movable along.

Further, in the pen block sliding mechanism for 2 channels, the 2 channel driving motor 342 and the 2 channel driving pulley 344 are connected to the flat plate 411 on the + Y direction side of the sliding bar 41, that is, 1 channel tension. The two-channel tension pulley 346 is arranged at a position adjacent to the pulley 345, and at the end of the sliding bar 41 facing the pulley 345, that is, at a position adjacent to the one-channel drive pulley 343. A drive belt 442 for two channels is wound around the pulley. The 2-channel pen carriage 422 is locked to the drive belt 442, and similarly to the 1-channel pen carriage 421, the flat plate 411 and the second plate 411 rotatably provided on the upper and lower portions of the carriage by the rollers 46. It is configured to be movable along a groove provided in the top plate 415. Therefore, these two carriages 421 and 422 are independently movably provided along the sliding bar 41.

The body portion of the Y-axis drive motor is generally much larger than the drive pulley, and if two drive motors are provided adjacent to each other, the width of the sliding bar in the X direction may increase. Although the sliding bar itself becomes large, it is possible to reduce the width of the sliding bar in the X direction by alternately arranging the drive motors for each channel so as to face each other as described above. it can.

Further, the pen block sliding mechanism moves in the X-axis direction based on the recording signal, but by arranging the heavy drive motors alternately facing each other as described above, the longitudinal length of the sliding bar is increased. The weight is balanced in the direction (Y direction), and the movement in the X axis direction can be performed stably.

[0015]

[Effect of device]

 As described above in detail, according to the pen block sliding mechanism of the recording apparatus of the present invention, the sliding bar can be formed to have a narrow width in the moving direction, which allows the recording apparatus to be downsized or the recording range to be widened. By simultaneously reducing the number of parts of the sliding mechanism, the sliding mechanism can be constructed inexpensively and lightly. Moreover, since the weight of the sliding bar can be well balanced in the longitudinal direction, it is possible to realize accurate and stable recording at high speed and high acceleration.
