Description of the Invention: [Technical Field] Field of the Invention The present invention relates to a coating of a die for supplying a coating liquid to a coating device such as a table coater. Liquid supply device. BACKGROUND OF THE INVENTION In the prior art, a device for supplying a coating liquid to a mold of a die coater is disclosed in Patent Document 1, and includes a coating liquid tank for containing a coating liquid, and suctioning the coating liquid. The coating liquid of the tank supplies the coating liquid to an injection sump of a coating device that relatively moves in a predetermined direction with respect to the table. The setting method of the syringe pump is a fixed type that is set at a position away from the coating and a mounting device (10) (four) that is mounted on the coating device and moves with the mold. In the fixed type, in order to ensure the moving distance of the coating device, the discharge line of the coating liquid between the injection fruit and the mold is long, and the pressure loss from the suppression line to the discharge line of the mold is large, and the adjustment coating takes time. problem. On the other hand, in the mounting type, since the injection pump moves together with the coating device, the discharge line of the coating liquid between the injection mold and the mold is short, and the coating liquid tank and the suction pipe material for injection are prepared. (10) Time growth. Because the mold and the syringe pump move at the same time, the weight is heavy, and a large driving force is required, which leads to a large-scale device, and the liquid coating tank and the injection tank are also provided with a coating liquid tank in the device. Internal maintenance space. Further, since the syringe pump is mounted on the coating device at a position higher than the mold, there is a problem that air easily flows into the syringe pump. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a suction and discharge of a coating liquid by a syringe pump. The coating liquid supply device has a short time and no air inflow. In order to solve the above problems, the coating liquid supply device of the present invention comprises: a coating liquid tank for accommodating a coating liquid; and a coating liquid for sucking the coating liquid tank, the coating liquid is supplied to be predetermined with respect to the table a syringe pump for moving the mold of the coating device; and a coating liquid for sucking the coating tank between the coating liquid tank and the syringe pump, and sending the coating liquid to the pressure of the injection pump a booster pump; the aforementioned injection pump is mounted on a side surface of the coating device in a direction perpendicular to a moving direction of the mold. The pressurized turbop is preferably an injection pump driven by an air cylinder. The aforementioned syringe pump is preferably disposed below the aforementioned mold. According to the present invention, since the coating liquid that sucks the coating tank is further provided between the coating liquid tank and the syringe pump, the coating liquid is sent out to the booster pump of the syringe pump, so even if the coating tank is The distance between the injection pump is long, and the coating liquid of the coating liquid tank can be rapidly sucked by the booster pump, and is supplied to the mold through the syringe pump. Since the coating liquid tank is disposed outside the apparatus by this, a sufficient maintenance space can be secured in the apparatus. Further, since the pump is pressurized by the booster pump, the syringe pump can be miniaturized and the apparatus can be miniaturized. 1331548 Therefore, the pressure loss is reduced, and the coating film pressure is easily adjusted. Since the syringe pump 9 is disposed on the side of the moving block 16 of the coating device 12, the injection 9 can be placed under the discharge port of the slit die 13, and the air can be prevented from flowing into the injection even when the coating device 12 is stopped for a long period of time. Pump 9. 5 [Simple Description of the Drawings] • Fig. 1 is a flow chart of the coating liquid supply device of the present invention. Fig. 2 is a side view (4) and a front view (b) showing the positional relationship between the coating liquid supply device and the coating device. • Fig. 3 is a side view showing the relationship between the coating liquid supply device and the other position of the coating device.
