摘要:
The present invention relates to a loading/unloading control apparatus of a semiconductor device and a control method thereof in which a time for loading/unloading a semiconductor device can be saved when a produced semiconductor device is loaded and unloaded to be tested. The present invention provides a loading/unloading control method of a semiconductor device including the steps of: determining whether a semiconductor device for being sorted to an unloading buffer exists by a microprocessor; determining whether a sorting tray has been prepared when the semiconductor device exists to be sorted to the unloading buffer; requiring the sorting tray to be replaced by the microprocessor when the sorting tray has not been prepared; and feeding the semiconductor device served at the unloading buffer to the sorting buffer by a X-Y axis picker during the replacing of sorting tray.

The present invention is a toy cap gun, which includes a gun housing having a forward end and a rearward end, a chamber, a barrel, a cap anvil, a hammer and a trigger. The chamber is formed of material which permits light from a cap firing flash to be visible therethrough, and the chamber further contains an effective amount of a glow in the dark material. Further, the chamber is movably located within the housing and the chamber and housing together are adapted to load and unload caps. The barrel is located at a forward end of the housing and the chamber. There is a rotatable cap anvil which is located on a rearward end of the chamber, extending into the chamber and adapted to hold caps. The hammer is located on the housing, is connected to a trigger mechanism and is located adjacent to the cap anvil for intermittently striking and detonating caps. There is a trigger mechanism extending from the housing and functionally connected to the hammer for intermittently impacting the hammer to detonate caps.

An inkjet image forming apparatus having an array type print head to stably deliver a printing medium through a printing zone. The inkjet image forming apparatus includes an array type print head including a nozzle part to discharge ink to a printing zone, a first rolling unit having a first nip portion to nip the printing medium, wherein the first nip portion is disposed before the printing zone to deliver the printing medium to the printing zone, and a second rolling unit having a second nip portion to nip the printing medium, wherein the second nip portion is disposed downstream of the first rolling unit in a delivery direction of the printing medium. A distance between the first nip portion and the second nip portion is less than or equal to 3 inches.

摘要:
An image forming apparatus including: a plurality of medium trays to stack a print medium having an image formed thereon by an image forming unit; a driving source to momentarily apply a direction switching signal; a selector to select a carrying path of the print medium having the image formed thereon, the carrying path directing the print medium to one of the plurality of medium trays; and a switch unit connected to the driving source to set a position of the selector in order to direct the print medium along the carrying path according to the direction switching signal. Accordingly, power is only used momentarily to direct the print medium to a medium tray from among a plurality of medium trays.
摘要:
An inkjet image forming apparatus and a method to control the same are provided to prevent a reduction in the print image quality due to inkjet nozzle deformation. The trajectory direction of ink inclined by inkjet nozzle deformation is corrected by controlling the amount of heat generated by a plurality of heaters that are arranged in parallel to the conveyance direction of paper for each inkjet nozzle provided on an inkjet head chip mounted in an inkjet print head.
