Description

[Detailed description of the invention] The present invention is directed to improvements in X-Y plotters.

X-Y plotters utilize and combine movements in the X-axis and Y-axis directions to create plots, but those that move the pen in both orthogonal axes have the problem of complicating the movement mechanism and making it heavy. ,In the case of devices equipped with several pens for multi-color drawing, multiple pens are often provided separately, which has the disadvantage of requiring time and effort to go to pick up the pens each time automatic replacement is required. The mechanism is complicated, heavy, and expensive.

The present invention was made to solve the above problems,
The purpose of this is to very easily perform the two operations of setting the pen to the operating position and selecting multiple pens.The mechanism for this is provided separately from the pen mechanism to reduce the weight of the pen mechanism, and the pen is mounted on a single orthogonal axis. An object of the present invention is to provide an X-Y plotter that enables quick and highly accurate plotting by moving the plotter only in one direction.

That is, the present invention includes a rotatable platen roll 1 provided in the direction of one axis of a rectangular coordinate system, and a rotatable platen roll 1 provided in the orthogonal coordinate system in order to move the printer paper p wound around the platen roll 1 in the direction of another axis orthogonal to the one axis direction. a paper pressing member 2 sandwiched between;
It consists of a pen mechanism 3 that is movable along the platen roll 1 and that can approach and separate from the drawing surface p' of the roll 1, and the pen mechanism 3 includes a guide installed parallel to the platen 0-roll 1. By the operation of a forward rotation shaft 7 and a reverse rotation shaft 8, which are connected via an axial clutch mechanism 6 to the output shaft of a forward and reverse rotation drive source 5 provided on the shaft 4 and on the main body side, the drawing surface p' This is an X-Y plotter that approaches and separates from the pen mechanism 3 itself, and selects a plurality of pens 9a, 9b, . . . of the pen mechanism 3 itself.

The present invention will be explained in detail below with reference to Examples. In each figure, 1

The pen actuating member 3 has a protruding piece 3m at its outer end that pushes up the main body 3b. 12 is the above pen mechanism 3
A pulse motor is a drive source that drives in the axial direction; 13 is a pulley 13a1 that connects the shaft portion 12a of the motor with a moving cable; and 9g is a pen holder 9 that accommodates various colored pens 98 to 9f. The attached mounting part is shown.

The pen mechanism 3 can be constructed as illustrated in FIG. 6 above. That is, this is a case where the pen operating member 3k is operated in the opposite manner to the above to put the pen mechanism 3 into the operating state, and the sixth
In the illustrated example, a pen separation spring 3j is interposed so as to push up the outer end 3f of the mechanism main body 3b, and this outer end 3
An engaging piece 3n that engages with the protruding piece 3m on the outer end of the pen operating member 3 is vertically provided at the lower part of the pen operating member 3, and the pen operating member 3k is connected to the spring 3j.
The outer end 3 f' of the main body is always locked in the downward direction against the elastic force of the pen mechanism 3 , and the lock is released by the operation of the normal rotation shaft 7 to put the pen mechanism 3 into the operating state. The hook piece 3q is unnecessary, and the other configurations are the same as those in the example shown in FIG. 3, so the reference numerals are the same and the explanation is omitted.

5 is a drive source capable of forward and reverse rotation; 6 is a clutch mechanism that operates the forward rotation shaft 7 or the reverse rotation shaft 8 depending on the direction of rotation; the clutch mechanism 6 in the embodiment The rotation of the output shaft 5a is transmitted by the gear sets 5b and '5G, causing forward and reverse rotation. A pivot shaft 14 and an axial clutch 15 that extracts, for example, normal rotation from the two-way rotation of the pivot shaft 14.
A sector gear 17 is engaged with the output gear 16 of the clutch, and the sector gear 17 is connected to the forward rotation shaft 7 of the pair of guide shafts described above, and the reverse rotation gear 1 is connected to the other end of the pivot shaft 14.

On the other hand, due to the reversal of the forward/reverse rotation drive 815, the pivot 14 is reversed, and the gears 18,
Since the operation is transmitted to the pin 19, the cam 20, the reversing shaft 8, the intermediate gear 22, and the pen selection gear 23, the pen holder 9 rotates and one of the pens 9a to 9f can be selected. Accordingly, the X-axis and Y-axis drive sources 11 and 12 are controlled by signals from a control system not shown.
When activated, the pen mechanism 3 is moved in the X-axis direction by the moving means 13 such as the pulley 13a due to the operation of the X-axis drive source 11, and the platen roll 1 is rotated by the operation of the Y-axis drive source 12, so that the roll 1 The printer paper p, which is held between the paper presser member 2 and the paper presser member 2, moves in the Y-axis direction, and the movements in both orthogonal axes directions are combined to produce a drawing.

As described above, according to the present invention, the printer paper p is hung around the platen roll 1 and moved in one axis direction of two coordinate axes such as orthogonal axes, and the pen mechanism 3 is made to move only in the other axis direction. As a result, the pen mechanism 3 and its moving structure can be simplified and injuries can be reduced, and since the influence of inertia is reduced, quick and highly accurate operation can be expected. 9a, 9b
..., so there is no waste in movement during automatic pen exchange, and since the pen cartridge is replaceable, it is easy to assemble and replace.Furthermore, the pen mechanism 3 makes contact with and separates from the drawing surface p', and one pen The automatic exchange operation is performed by dividing the output of a single forward/reverse rotation drive source 5 into forward and reverse rotations via a clutch mechanism 6, so that the pen mechanism 3 can be driven by the pens 9a and 9b.
