Abstract: A printing module for use in a large ink-jet printer includes a frame and an ink-jet unit secured to the frame. The ink-jet unit has a group of ink cartridges to emit droplets of ink onto a media to be printed. At least one irradiator is disposed at a side of the frame for casting a beam of ultraviolet light downward to irradiate and dry the droplets of ink emitted on the media, and means is provided for adjusting the position of the irradiator in forward and backward directions with respect to the frame. The printing module can be used in the large ink-jet printer to produce a sharp print.

Abstract: An ink stirrer for a large ink-jet printer is disclosed. The ink stirrer includes a spindle designed to be pivotally disposed within an ink cartridge, and at least one blade extending downward from the spindle. Furthermore, one said blade is provided with a bottom lump having a large mass that the blade may swing to and fro within the ink container and thereby stir the ink as a result of the reciprocating movement of the carriage during the printing process.

Abstract: A printing device for inkjet printing machine includes a base having a printing unit connected thereto and the printing unit includes a plurality of printing heads and ink cartridges. An UV beam generating device is connected to a side of the base and has an aperture defined in an underside thereof so that the UV beams goes through the aperture and toward an object to be printed. An anti-scattering device is connected between the printing heads and the aperture so as to keep the UV beams away from the nozzles of the printing heads.

Abstract: An adjusting device for adjusting printing heads of inkjet printing machine includes a base connected to a printing unit and a plurality of printing assemblies are respectively connected to the base. Each printing assembly has a printing head connected thereto and a connection board is connected to an end wall of each printing assembly. Three adjusting members extend through the end board and contact against the end wall, and the three adjusting members are located at three peaks of an imaginary right triangle on the end board so as to adjust the printing head in different directions. A fourth adjusting member extends through the end board and is fixed to the end wall. The fourth adjusting member is located at a center of weight of the imaginary right triangle.

Abstract: A safety device for a toy gun has first and second firing pins which can block movement of a trigger. The firing pins are electro-magnetically operated. The first firing pin is normally in a position which blocks movement of the trigger and the second firing pin is normally in a position which allows movement of the trigger. A power source is connected to the first firing pin by a switch so that trigger movement is blocked by the first firing pin until the switch is activated. The switch also connects the power source to a photo-electric switch which includes a light emitter and a light sensor. The second firing pin is connected to the power source by the photo-electric switch so that movement of the trigger is blocked by the second firing pin only when the photo-electric switch is closed. The photo-electric switch detects the presence of a target within a preset range of the toy gun and closes if a target is detected.
