Title: Image forming device
Inventor: AKIYAMA YASUHISA
IPC: G03G21/00
Filed: 1984-04-27
Abstract: PURPOSE:To eliminate misoperation and to improve operability by inhibiting a selection of a developing device unless at least one of plural detachable developing devices is attached. CONSTITUTION:The 1st and the 2nd developing devices 321 and 322 of a developing device 10 are provided to a main frame detachably. Developing device presence/absence signals from the 1st and the 2nd developing devices 321 and 322 are used after the power source is turned on to check whether a developing device is attached and detached or not and when not, a signal from a cover opening/closing detecting device 13 is used to check whether the developing device is attached securely or not. When the cover opening/closing detecting device 135 detects the closure of a hopper cover 131, it is decided that the developing device is attached. Then, a developer on the sleeve of the attached or detached developing device is removed and a stand-by state is entered. Thus, when both or either of the 1st and the 2nd developing devices is not attached, a selection of a developing device is inhibited, so there is no misoperation and the operativity is improved.

Abstract: PURPOSE:To obtain an about X6 high power variation ratio and an about 55 deg. wide view angle by composing an objective system of four groups which have a positive, a negative, a negative, and a positive refracting power in order from the object side. CONSTITUTION:The objective system 1 consists of the four groups which have the positive, negative, negative, and positive refracting powers in order from the object side in order to obtain the high power variation ratio, and the power is varied by moving the 2nd group 12 and 3rd group 13 in the direction of the optical axis. Further, the 1st group 11 and 2nd group 12 include aspherical surfaces in order to sufficiently compensate aberration variation due to the power variation. Further, the 4th group 14 consists of one element and includes an aspherical surface to widen the view angle. In the positive, negative, negative, and positive type objective lens system 1, the variation in aberration due to the power variation is generated mainly by the, 1st group 11 and 2nd group 12. The 1st group 11 and 2nd group 12 includes aspherical surfaces to suppress the variation in aberration due to the power variation. The introduction of the aspherical surfaces into the 1st group 11 and 2nd group 12 gives effect to the compensation of distortion which is a problem when the view angle is widened.
