摘要： PROBLEM TO BE SOLVED: To eliminate the development of bubble as the factor of poor printing in a print head by a method wherein a delivery side tube for feeding ink from the discharging port of a pump to the print head is inserted through the ink feeding port of the print head in the print head under the condition that an antibackflow device is annexed to the tip of the tube. SOLUTION: A supplementary feed ink tank 6 and a print head 3 are connected to each other by a delivery side and a suction side tubes 7a and 7b through a pump 5. When the residual amount of ink 13 in the print head 3 stands below a certain amount, the pump 5 is put into actuation on the basis of the detection signal of an ink residual amount detecting part 8. Thus, the ink 13 in the supplementary feed ink tank 6 is fed in the print head 3 by the amount controlled at a controller part. At this time, due to the pressure reducing effect of a diode 12 as an antibackflow device, the ink feeding pressure in the print head 3 is lowered, resulting in preventing the mixing of air in the tubes 7a and 7b due to head as the cause of bubbling from developing.

摘要： PURPOSE:To prevent a sheet material to be cut from deformation and margin dislocation, facilitate picking up, and enhance the transfer efficiency by installing in line a plurality of conveyor devices, and moving the seat for a sheet to be cut in a single piece with a sheet supporting means at each stage of processing. CONSTITUTION:A M system for a sheet material includes a cutting area A where a specified pattern piece P is cut, a loosening area B where the roll form material is spread and a stack L is formed, and a pickup area C where cut pieces are picked up. Therein a cutting seat 4 on which the sheet material spread in the loosening area B is placed is transferred in the form as it is to a cutting table 1 in the cutting area A. The cutting table 1 performs specified cutting operation on the cutting seat 4. At the same time, the sheet material on the cutting seat 4 after completion of cutting is transferred in the form as it is to a pickup table 11 in the pickup area C.

摘要： PURPOSE:To execute a highly accurate recording automatically without damaging a sheet material by composing the title device so as to discharge a recording medium only during the ascent or descent of a hollow needle and to record the same information on all of the sheets of a lamination body with the vertical operation of one time on the laminated sheet like material. CONSTITUTION:A height detecting sensor 28 is set to the position equivalent to the thickness of a multiple layer sheet 3 in advance by a detection position adjusting device 29 installed at the syringe block 27 side. A push rod 21 and push rod block 11 are made free by releasing a solenoid brake 30 at the timing detected by this height detecting sensor 28, and the push rod 21 is ascended without pushing a piston 22 by being pushed by the ascent of the piston 22. This piston 22 goes to sink down into a cylinder 24 by the discharging part whenever discharging a recording medium 23 and by repeating this operation recording can be performed normally until the recording medium 23 is eliminated.

摘要： PURPOSE:To improve the operability of the titled head device with a simple device, by interrupting the working of a drawing tool or a working tool with the safety function after discriminating the color of the table surface selected previously from the color of a sheet matter. CONSTITUTION:The X rails 2 and 2' and a Y rail 5 are provided on the surface 1' of a table 1 of an automatic drawing machine, and X cursors 3 and 3' mounting X driving motors 4 and 4' are set to the rails 2 and 2'. Then a Y cursor 6 is attached freely movabl to the rail 5 set between cursors 3 and 3'. A Y driving motor 6 and a drawing head 8' are mounted on the cursor 6. The head main body 8b of the head 8' is provided to holes H1-H4 through which a drawing tool is inserted, and at the same time color mark sensors 8c and 8d are provided in the moving direction of X and Y axes in advance from the holes H1-H4. Both the color of the surface 1' and the color of the paper 11 on the surface 1' are selected previously, and these colors are discriminated by the sensors 8c and 8d. According to the result of this discrimination of colors, the moving-down of the drawing tool is interrupted. Thus the operability is improved for an automatic drafting machine.
