Title: Device for transferring recording medium for printing machine
Inventor: SATOU AKIRA
IPC: B41J21/16
Filed: 1978-08-23
Abstract: PURPOSE: To provide a device mentioned to in the title, capable of affording a high-speed continuous printing by using a stepping motor for transferring the printing medium and arranging such that the transfer is stopped at each time of typing by an electric signal which is issued by a photoelectric conversion element adapted to detect perforation in the recording piece.  
     CONSTITUTION: A rotary link 22 keeps a limit switch 14 during a movement of a rotary arm 16 from a point A to a point C where the printing by a printing head 13 is finished, so that a monostable multivibrator circuit 41 operates to produce pulses. A flip-flop circuit 42 is set by the falling of each pulse to open an AND gate 43. In consequence, a stepping motor 9 is energized upon receipt of an output pulse from a pulse generating circuit 44 thereby to transfer a web-like recording medium 3. As the arm 16 reaches a point D, the next printing piece 5 is moved to the printing position so that a photoelectric conversion element 30 detects a perforation of a printing piece and produces a pulse signal the falling of which resets the flip-flop circuit 42. In consequence, the flip-flop circuit 42 is reset by the rear end of the pulse signal so that the gate of the AND gate circuit 43 is closed to stop the stepping motor 8, whereby a typing is made on the web-like medium 3 in the stopped condition.

Title: Driving device of scanning member which makes reciprocative motion
Inventor: MURATA TOMOJI
IPC: G03B27/62
Filed: 1979-08-10
Abstract: PURPOSE: To shorten the distance to be preliminarily moved and decrease the load of the driving system by giving an initial speed to a scanning member by energizing force of elastic means thereby increasing the rise to a predetermined speed.  
     CONSTITUTION: A scan clutch SCL goes ON to rotate the driving transmission pulley 17 fixed to a shaft 40, by which an optical system is moved and scanning performed. Even if the optical system stops upon ending of the scanning, the shaft 40 is rotated by the repulsive force of a return spring 50; therefore, the return is smoothly accomplished when a return clutch RCL goes ON and the return is performed. When the optical system returns to the scan starting position, the scanning is started by the repulsive force of the scan spring 59 having been charged on the verge of the return end and when the preset speed is reached, the scanning is continued by ON of the scan clutch SCL, thus the image exposure is started.

Title: Optical separator
Inventor: ENDOU KIYONOBU
IPC: G02B27/10
Filed: 1980-07-25
Abstract: PURPOSE:To equalize the relation of a position between a photodetector and a luminous flux distribution of a separated light beam from an optical separator, as to each photometry system, by setting a position of a condensing point to a position of the photodetector by making a relief grid have a curvature. CONSTITUTION:A relief grid of an optical separator 302 is arrayed on the concentric circle which has an F point as the curvature center, or on the spiral, and in the luminous flux which is made incident to the optical separator, a component in the section passing through the curvature center F proceeds to the curvature center F by total reflection on the upper surface and the lower surface. It is converged to a point F' by refraction in case of getting out in the air from the projection end. In the vicinity of this convergence point F' exist locally a lot of luminous flux components which are made incident vertically to the optical separator, therefore, when a photodetector is placed in the vicinity of F', proportionality of an F value is deteriorated. Accordingly, the curvature center is moved in order to separate the detector from the condensing point, and the accuracy is maintained as a position of the detector remains fixed.
