Title: Print antenna
Inventor: NAITOU HIROSHI
IPC: H01Q9/04
Filed: 1992-02-14
Abstract: PURPOSE:To improve the band width of the gain versus frequency characteristic of the antenna element and the cross polarized wave characteristic or the circularly polarized wave characteristic simultaneously by providing two strip conductors formed in a window and a short-circuit conductor for setting use to the antenna. CONSTITUTION:The antenna element made of two strip conductors in a window 12 is formed on one side of an insulating board. In this case, the middle of the two strip conductors 10 is in connection to an edge of the window 12 by a short-circuit conductor 11. Moreover, a transmission line 14 for excitation is formed on the other side of the insulation board. Since the two strip conductors 10 are formed in one window in this way, the frequency band width is wide and the width of each strip conductor is narrow, and only one resonance mode is in existence and the operation is made stable. Furthermore, undesired radiation from the window 12 is suppressed effectively by using the short-circuit conductor 11 connecting the middle of the strip conductors 10 in the lengthwise direction, the window 12 and the ridge.

Abstract: PURPOSE:To aim at the shortening of original changing time by installing an original conveying port in the neighboring upstream of an image reading position on a platen, and conveying the second original up to a standby position being not on a platen adjacent to the image reading position in advance. CONSTITUTION:A lowermost original of an original bundle 2 mounted on a tray 1 is fed piece by piece by a semicircular roller 4, a feed roller 5 and a separate belt 6, while its tip is made to bump against a nip part of each of feed rollers 9a, 9b in nonoperation whereby its skew is remedied and thus the original is on standby. Next, a feed roller 9 and a conveyor belt 11 are driven by a motor 12, feeding the original onto platen glass 101, and an original surface is read by means of optical scanning, and when it is a duplex original, it is again fed onto a platen 101 by c.w or c.c.w. rotation of the motor 12 via reverse rollers 16, 17 and when an original rear end is passed through an interval between feed sensors 8a and 8b, the next original 2 is fed and made to be on standby. When discharge of the read original is detected by a paper discharge sensor 19, the next original is fed onto the platen 101. Thus, a span of original changing time is reducible.

Filed: 1988-03-16
Abstract: PURPOSE:To prevent a paper jam from occurring as well as to make the promotion of high speediness attainable by changing paper feeding time and speed to the optional time and speed according to a paper feeding interval, and constituting it to compensate the paper feeding interval. CONSTITUTION:A paper feeding interval is measured by a table central processing unit 9 at each time when a rear end of a preceding sheet of paper 12 run past a final table feed roller 17 by a table sensor 15 and when a tip of a succeeding sheet of paper is reached to the table sensor 15. The paper 12 passed through the table feed roller 17 of an LCIT (large quantity paper feed tray) 5 is fed at constant speed by a resist roller 16 of a body 1. Then, whether the paper feeding interval is more than 40mm, by way of example, or not is judged by the central processing unit 9, and if YES is the case, the paper feeding interval is barrowed by stepping up rotation speed of an LCIT motor 10 as far as, for example, 50%, then if a specified period of time (for example 0.4sec) has elapsed, the motor 10 is put back to the normal speed. Thus, the paper feeding interval is narrowed for compensation.

Abstract: PURPOSE:To make the captioned device smaller and lighter and improve workability and feed speed controllability by moving the inside circumferential surface of a freely reciprocatable upward or downward in the tapered part of the catching part so that the stationary and above-mentioned electromagnets are suitably energized or de-energized. CONSTITUTION:The inside circumferential surface 10' of an electromagnet 10 is moved upward at the tapered part 8' by the pressing force of a spring 11 interposed between the electromagnet 10 and suction plate 9 to put a welding wire 2 in a tight state. At this time, the electromagnet 10 is held released of the excitation. Next, when a stationary electromagnet 12 is energized, it sucks a suction plate 13. Since the suction plate 13 is mounted integrally with the electromagnet 10 and distance piece 15 and is made slidably with a frame 16, it is moved in the state that it is holding the wire 2, whereby feeding is accomplished. Next, the electromagnet 10 is energized to release the wire 2. Thence, when the electromagnet 12 is de-energized in the state that the electromagnet 10 is held energized, those other than the wire 2 return to the original state. By repeating the above, the wire 2 is fed in the arrow direction.
