Title: Image forming device
Inventor: YABEI TOSHIYA
IPC: G03G15/00
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To make transfer paper obliquely fed to be in the correct state by changing drive of carry roller parts based on detection of the oblique feed state of the transfer paper so as to correct the carrying direction. SOLUTION: Transfer paper 11 delivered from a paper feed part and carried is detected by paper detecting sensors S1, S2, directly after passing through carry roller parts 41a-41c. At the time, when the right side of the carried transfer paper precedingly advances and the left side becomes in a delayed state while skewing the transfer paper 11 for example at an angle θ, difference is generated in times detecting the transfer paper 11 with the paper detecting sensors S1, S2. In a drive control circuit, this time difference is feedbacked, converted to the command signals of rotating speed to right and left stepping motors 45, 47 so as to eliminate the time difference, and the rotating speed of the right side drive roller 41c is decreased or the rotating speed of the left side drive roller 41a is increased. Hereby, the transfer paper 11 is corrected in its skew and sent in the correct posture.

Title: Igniting-heating mechanism
Inventor: YAMAUCHI KUNIO
IPC: F24V30/00
Filed: 1992-02-14
Abstract: PURPOSE:To enable generation of intense heat by using an igniting bulb having a construction wherein a pair of electrodes one of which is shaped in a needle and the other of which is coated with an igniting agent are disposed in a container separately from each other, oxygen is enclosed in the container and the container is sealed hermetically.
