While rotating the gear wheels 19 and 19 ', which mesh with the gear 21, against the resistance of the friction plate 17, the actuating piece 29 stops the stopper limit limit on the base 13. The operation is carried out by again the operation done in the state of FIG. 1 as the Y-phase to reach the value 30 described above with the rapid drive is forced rearward.

Incidentally, the present embodiment exemplifies engraving by photo-injection of the original A, but instead of the original A, the image of the TV or VTR is converted into an electrical signal and the slide table D is executed by the engraver G. An image or the like may be engraved on the card C of the image.

The present invention as described above is driven by a ram (4) swinging from side to side around the support shaft (3) through the sliding exerciser of the sliding movement driving piece (9) axially supported by the rotating disc (2). The reciprocating drive of the slide table (D) in the X-axis direction does not require a special hydraulic generator, such as driving with a conventional hydraulic cylinder, and also requires a large turning radius such as driving with an eccentric cam. It can be manufactured inexpensively in a small size without increasing the size.

Moreover, the ram 4 is formed in a columnar shape, and sliding motion members such as the sliding motion driving piece 9 and the sliding motion moving piece 7 which slides on both sides of the ram 4 are in polygonal contact with other polygons, and the sliding support It operates smoothly and quietly without generating vibration. In addition, even if dust adheres to the sliding surface of the ram 4, the sliding surface is contacted with the polygon and is removed by the sliding movement, so that no dust enters the contact surface. An interference fringe occurs in the image due to the transfer unevenness of the table D, and no defect is generated, and the image can be carved clearly and accurately.

In addition, the carving drive device 1 moves the ram 4, which rotates around the support shaft 3, to the left and right by the sliding movement driving piece 9 on the rotating disc 2 to move the slide table D to the X axis. A swing slide crank mechanism for reciprocating in the direction is used, and it is a kind of high speed return mechanism in which a return time of the return line S is accelerated with respect to the transfer of the engraving line R shown in FIG. The density of the slice R on C) becomes large, the fidelity of the image is remarkably improved, and a clear image can be engraved.

In addition, the slide mover can be used for a long period of time without the need to replace the constituent members by contacting the other surface to make it move smoothly when the number 1 of the polygons is in surface contact and wear or the like occurs. When the time ratio of the reciprocating drive of the slide table D is to be changed, the time ratio can be simply changed by changing the distance from the center of the rotating disc 2 to the support shaft 3 of the ram 4. As a result, an image of required sharpness can be easily carved.

On the other hand, the feed in the Y-axis direction such as the engraving machine (G) is connected to the lower surface of the base 13 by the friction plate 17 to the support member vertically displaceable by connecting the elastic support plates (15, 15 ') to each other It is configured to drive the screw shaft such as the worm gear 21 between the gear wheels 19 and 19 'which are rotated against the friction plate 17 when it is stopped and applied external force normally, and the screw shaft is eccentric. Even if there are deviations due to the mounting error as well as shaft bending, there is no need to perform high precision machining or planting, such as driving the screw shaft by driving the nut with a conventional nut, No rotational impairment or transfer unevenness due to change, etc., is absorbed sufficiently, and the gear wheels 19 and 19 'are engaged by pressing the screw shafts from both sides and absorbing the backlash of the screw. To be subjected to efficient transport and operation to that for creating the device cheaper to fidelity piece high image.

In addition, on the upper surface of the base 13, the belt 23 driven by the motor M2 travels in any of the positive and reverse directions in contact with the upper surface of the base end side in the Y axis direction in parallel with the screw axis. Arranged freely, above the belt 23, the lever 25 coupled with the eccentric cam 28 is axially supported so that the belt 23 can be opened and closed freely up and down, and the engraving of the engraver G The transfer operation to the starting point or the reversal operation in the middle is performed by moving the lever 25 downward and inserting the belt 23 to attach the gear wheels 19 and 19 'mounted on the base 13 to the friction plate 17. By rotating against the screw shaft, the base plate 13 can be sent quickly in the Y-axis direction, so that the processing time of the cards C can be significantly shortened and a large amount of cards can be carved. Furthermore, the quick sending operation is performed by the clutch operation of the lever 25, and the engraver G is lifted together with the lower driving of the lever 25, so that no damage is caused to the card C during driving. It has many salient features.

As described above, the present invention has the following effects.

In the image engraving apparatuses of claims 1 to 3, the sending and reverting operation of the engraving machine to the engraving start point can be speeded up, and the engraving processing time on the cards can be significantly shortened.

In the image engraving device of claim 4, even if there are deviations due to eccentricity, axial bending, and attachment error of the screw shaft, there is no need to perform high precision machining and drilling as in the prior art, and change of frictional resistance of the screw shaft. Rotation impossibility and transfer nonuniformity do not occur by. Furthermore, by absorbing the backlash of the screw, the device can be manufactured economically, and smooth transfer operation can be performed to manipulate images with high fidelity.

In the image engraving apparatus of claim 5, it is possible to manufacture the apparatus inexpensively without requiring a special hydraulic pressure generating apparatus as in the prior art and without increasing the size of the apparatus.

In the image engraving device of claim 6, no vibration is generated and smooth operation is performed. In addition, even when dust adheres to the sliding surface of the ram, the sliding surface is contacted with a polygon to remove the dust, and dust does not enter the contact surface, resulting in no image defect.
