Title: Both-sided grill device
Inventor: MORITA SHINICHI
IPC: A47J37/06
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To substantially completely prevent uneven grilling by forming passing holes for passing an air current. SOLUTION: Notches 9 for passing some of convection heat from a lower burner are formed at equal spaces extending over the longitudinal direction of a guide plate 3b in a guide plate 3b. To prevent increase of uneven grilling due to excessive heat reaching both side parts of a grill net, the number and size of notches 9 are suitably considered. Further, the width D of the guide plate 3b is made wider than that in the conventional structure. This is the reason why convection heat from the lower burner is spread equally extending over the grill net.  Thus, in addition to the function of spreading convection heat of the lower burner originally possessed by the guide plate 3b, a function of making some of convection heat reach both side parts of the grill net 7 through the notches 9 is provided so that convection heat is substantially completely equally spread over the whole surface of the grill net. Accordingly, uneven grilling can be prevented substantially completely.

Abstract: PURPOSE:To reduce vibration of a photo-sensitive member and improve quality in recording operation by a method wherein there is provided a vibration-proof member for preventing vibration of the second gear train for driving another member from being transmitted to the photo-sensitive member through the first gear train. CONSTITUTION:A driving motor 34 is driven to rotate the first motor gear 33 and the second motor gear 35 and then a photo-sensitive member 11 is rotated through the first row of gears G1. In turn, a driving force of the driving motor 34 is transmitted through the second gear train G2 so as to drive a developer device or a cleaning device or the like. When the developer device or the cleaning device is driven, vibration transmitted to the first gear train G1 through the second row of gears G2 is accommodated by the vibration-proof shock absorbing member 38. Accordingly, it is possible to prevent vibration transmitted from the second gear train G2 to the photo-sensitive member 11. With such an arrangement, it is possible to reduce vibration caused at the photo-sensitive member or deterioration in recording quality.
