Title: Comparison type inspector
Inventor: KAWASHIMA HIDEAKI
IPC: G01N21/94
Filed: 1981-06-24
Abstract: PURPOSE:To facilitate the highly accurate focusing as a whole, by putting an automatic focusing mechanism of the other side on an automatic focusing mechanism of one side and contiguously to a reference object and then putting an object to be inspected on the automatic focusing mechanism of the other side. CONSTITUTION:An automatic focusing mechanism 12 which cooperates with an objective lens 11 is set on an XYO table 10, and a supporting stage 13 is attached to the mechanism 12 to support a reference mask 1. Thus the reference mask pattern is visible through the lens 11 with magnification. A small-sized XYO table 14 is put contiguously to the stage 13, and then a mask 2 to be inspected is set to the table 14 along with another automatic focusing mechanism 15. Thus the pattern of the mask 2 is visible with magnification through an objective lens 16. The mask 2 has substantially satisfactory focusing state according to the focusing of the mask 1 since the stages 13 and 14 have nearly the same height. Furthermore the position shift between both masks is compensated by the mechanism 15. As a result, the highly accurate focusing is possible in an easy way.

Abstract: PROBLEM TO BE SOLVED: To perform an automatic double image formation in a device having a vertical U-shaped path by selectively switching the carrying direction of a sheet subjected to image formation to either one of a second sheet support means and a reversing means. SOLUTION: A sheet P carried to a fixer 9 after transferring a toner image to the first surface thereof in an image forming part is sent to a reversing device 13 through a second carrying path 14 by a flapper 24 and a pair of second carrying rollers 25. When the rear end of the sheet P reaches about the nip of a pair of reversing rollers 26, a reversing flapper 27 is switched, and the reversing rollers 26 make the sheet P switch back so as to be sent to a delivery carrying passage 31. Further, the sheet P is carried onto the multi- paper feed tray 4 of a device body by a pair of reversed paper carrying rollers 32. The image formation is performed again to the second surface of the sheet P. The sheet P subjected to the image formation to the second surface is guided to a pair of discharge rollers 11 by the flapper 24 and discharged onto a discharge tray 10 by the discharge rollers 11.

Title: Printing head drive controller
Inventor: KOZAI FUMIO
IPC: B41J25/304
Filed: 1986-04-25
Abstract: PURPOSE:To enable the low noise generation of the titled controller, by driving a DC motor by the pulse of which the width or the crest value is almost proportional to a motor load torque. CONSTITUTION:If a positive energization pulse is applied to a DC motor 9 when a link pin 13 is at a position of 0 deg. in rotary angle, a drive gear 10 is rotated counterclockwise and a follower gear 11 is rotated clockwise. Therefore, the link pin 13 is moved to a position of 240 deg. in rotary angle along a guide groove 14 and a link lever 16 is also displaced leftward. Following this displacement, a tensile coil spring 6 acts on a head driving lever 5 and a printing head 3 is pressurized onto the front of a platen 2. because the width of a pulse is almost proportional to a motor load torque, the rotational frequency of the motor 9 is kept constant and the collision noise where the link pin 13 strikes against the guide groove 14 becomes small. Further, if a negative pulse is applied to the DC motor 9 when the link pin 13 is at a position of 240 deg. in rotary angle, the gears 10 and 11 are rotated reversely to each other. After the lever has been displaced rightward, the pin 13 is located at a position of 0 deg. in rotary angle and the printing head 3 is separated from the platen 2. The shock noise at that time when the pin 13 strikes against the groove 14 becomes also small.
