[Embodiments of the invention]

The present invention will be explained below with reference to embodiments shown in the drawings. Note that the same components as those of the conventional device described above are denoted by the same reference numerals in the drawings, and the explanation thereof will be omitted.

FIG. 1 shows an embodiment of the present invention, in which the platen 2
A round bar-shaped guide rail 3 extending in a direction parallel to the axis of
is arranged, and this guide rail 3 is connected to the carriage 2.
The cylindrical base 27 of No. 6 is inserted therethrough. Therefore, the carriage 26 can swing around the guide rail 3. Both ends of a wire 29 wound around a driving pulley 28 and a driven pulley (not shown) are connected to the lower portions of both ends of the cylindrical base 27 in the axial direction of the guide rail 3, and the driving pulley 28 is connected to a motor (not shown). It is designed to be driven in the direction of the arrow shown in the figure.

Therefore, the carriage 26 can reciprocate along the guide rail 3 in the axial direction of the platen 2 by driving the motor.

A pair of arcuate pen guides 30 and 31 concentric with the arc of the platen 2 are provided on the carriage 26 and project upwardly at a distance in the axial direction of the guide rail 3. 31, a pen guide 30 having an L-shape in a planar state and a pen guide 31 having an inverted-shape are arranged to face each other. Further, a bracket 32 is provided laterally protruding from the outside of one of the pen guides 31, and a rotor 33 is rotatably supported on this bracket 32 by a pin 34.

The rotor 33 has a pulley 35 and a gear 36 coaxially connected to each other, and a wire 38 wound around a drive pulley 37 and a driven pulley (not shown) is connected to the pulley 35.

This wire 38 is driven by a motor (not shown) in the direction of the arrow shown in the figure, and therefore, the rotor 33 is rotated about the pin 34 in the direction of the arrow shown by the drive of this motor.

A plate-shaped pen slider 39 is engaged with the pen guide 30.31 and can move up and down along the pen guide 30.31 as shown by the arrow. Arc-shaped engagement recesses 40.41 that engage with the pen guide 30.31 are formed on both sides of the pen slider 39 to extend in the vertical direction. A gripping member 42 is protruded from below to grip the pen guide 31 relatively tightly so that the pen slider 39 does not come off the pen guide 30.31. Further, an arc-shaped gear 43 that meshes with the gear 36 of the rotor 33 is vertically disposed on the gripping member 42.
3 rotation causes the pen slider 39 to move to the pen guide 30.3.
It moves up and down along 1.

A boss 44 is formed on the pen slider 39,
A ben 45 is pushed through this boss 44, and this ben 45
The front end faces the vicinity of the platen 2. Further, a stopper 46 having a diameter larger than the inner diameter of the boss 44 is provided around the outer periphery of the ben 45 to prevent the ben 45 from being pulled out forward. Further, the rear end of the ben 45 is held by a pen holder 47 attached to the pen slider 39, and a buffer coil spring 48 is interposed between the pen holder 47 and the pen 45. Further, an opening 49 is formed at the rear end of the pen holder 47, and an ink supply tube 50 is connected to the ben 45 through this opening 49.

Behind the movement range of the carriage 26, a rocking body 51 extending in a direction parallel to the axis of the platen 2 is arranged so as to be able to rock around a longitudinal support shaft 52. The support shaft 52 is connected to a motor (not shown), and is configured to swing the swinging body 51 in the direction of the arrow shown in the drawing. A pushing plate 53 is attached to the upper surface of the swinging body 51, and the carriage 2 is mounted on the pushing plate 53.
A roller 55 rotatably supported by a frame 54 protruding from the rear of the roller 6 can be moved.

Next, the operation of the embodiment described above will be explained.

First, in order to move the ben 45 only in the horizontal direction, that is, in the axial direction of the platen 2, the drive pulley 28 is rotated by a predetermined angle by a motor (not shown), and the drive pulley 3
7 is rotated by a predetermined angle in the same direction as the drive pulley 28 at a new circumferential speed. Then, the wire 29 travels a predetermined distance,
A carriage 26 connected to this wire 29 is moved in the horizontal direction. At this time, the rotor 33 supported by the carriage 26 is subjected to a rotational force due to the running of the wire 38 and a rotational force in the opposite direction due to the running of the carriage 26, and the two rotational forces are canceled out, so that the rotor 33 does not rotate and the pen 45 is not moved vertically.

Further, in order to move the pen 45 in the vertical direction, that is, in the circumferential direction of the platen 2 and in the horizontal direction, a motor (not shown) rotates the drive pulley 28 and the drive pulley 37 by a predetermined angle so that the peripheral speeds are different from each other. Then, the pen 45 is moved in the horizontal direction by the movement of the carriage 26, and a rotational force is applied to the rotor 33 due to the difference in running speed of both wires 29, 38, and the rotor 33 is rotated by a predetermined angle. 33 and the gear 43 of the Ben slider 39, the pen slider 39 moves to the Ben guide 30.
．． 31. Therefore 1. The pen 45 is moved not only horizontally but also vertically. moreover,
To move the pen 45 only in the vertical direction, use the drive pulley 28.
It is sufficient to stop the drive pulley 37 and drive only the drive pulley 37.

Next, in order to move the pen 45 in the two directions of the platen to perform printing, a motor (not shown) moves the support shaft 5 of the swinging body 51.
2 by a predetermined angle clockwise in the figure. Then,
The pushing plate 53 pushes the roller 55 of the carriage 26, and the carriage 26 swings clockwise around the round bar-shaped guide rail 3 against the tension of the wire 29, so that the tip of the pen 45 is placed on the platen 2. It is pressed against recording paper (not shown).

Note that during pressure contact, the pen 45 is moved back by compressing the coil spring 48, so that the platen 2 and the pen 45 are not damaged. Further, in order to separate the tip of the pen 45 from the recording paper, it is sufficient to stop the motor that rotates the support @52. Then, the carriage 26 swings counterclockwise in the figure due to the tension of the wire 29, and the tip of the pen 45 separates from the recording paper.

Therefore, the pen 45 is positioned by driving the motor that drives the drive pulley 28 and the drive pulley 37 in accordance with the control signal, and the pen 45 is moved in the direction of the platen 2 by driving the motor. Characters, figures, etc. can be recorded on recording paper.

In addition, in order to record large characters or figures that exceed the range of vertical movement of the pen slider 39, the drive pulley 37 should be rotated in synchronization with the drive pulley 28 so that the pen 45 is moved only to the horizontal position, and then the platen should be moved. 2 is rotated by a motor (not shown).

As explained above, according to this embodiment, the carriage 2
There is no motor mounted on the pen holder 47, and since the pen 45 is moved in the two directions of the platen by swinging the carriage 26, there is no need to provide an electromagnet in the pen holder 47.
Therefore, the carriage 26 as well as the pen slider 39
can be made smaller and lighter. As a result, the carriage 26 and the pen slider 39 can be positioned at high speed, and printing efficiency can be improved compared to the conventional system.

〔Effect of the invention〕

As described above, according to the present invention, the excellent effect of making the carriage smaller and lighter and enabling high-speed printing can be achieved.
