Title: Cleaning method for heat fixing device
Inventor: MOCHIZUKI MITSUO
IPC: G03G21/00
Filed: 1988-08-30
Abstract: PURPOSE:To rub stains of a heat roller with recording paper and to clean a heat roller by generating a speed difference between the traveling speed of the recording paper and the peripheral speed of the heat roller while the recording paper is sandwiched. CONSTITUTION:When recording operation is not performed, the recording paper 21b is supplied to between the heat roller 29a and backup roller 29b of the heat fixing device. Then the speed difference is generated between the recording paper 21b and heat roller 29a to rub offset toner, etc., off the surface of the heat roller 29a with the recording paper 21b, thereby cleaning the heat roller 29a. The stained recording paper 21b is discharged and disposed. Consequently, the heat roller is cleaned without providing any cleaning device.

Title: Transported article aligning apparatus
Inventor: SHONO SHINKICHI
IPC: B65G47/30
Filed: 1984-10-15
Abstract: PURPOSE:To prevent the posture of a transported article from being disturbed by bringing an aligning means into contact with the transported article while it is moved in the transport direction in the above apparatus for a sheet glass. CONSTITUTION:A plurality of sheet glasses 13 are laterally arranged side by side, and transported from a roll conveyer 2 to a belt conveyer 1. After the lapse of a fixed time since a limit switch 12 detected the sheet glass 13, a d.c. motor 10 is driven to travel a chain 9 at higher speed than the belt conveyer 1, whereby an aligning means 11 is brought into contact with the sheet glass 13 from the trailing end of the sheet glass 13 to laterally align the transport direction. Subsequently, the turning speed of the aligning means 11 is gradually decreased to separate the aligning means from the trailing end of the sheet glass 13, and the aligning means is stopped in due time. In this arrangement, the posture of the transported sheet glass can be prevented from being disturbed.
