Abstract: To provide a projector capable of increasing F number of an illumination system without enlarging the size of the illumination system or the like. A combining lens 43a operating in cooperation with a superimposing lens 35 is provided only in a first section between a first dichroic mirror 41a and a red light reflection mirror 42a as a bending mirror on a first optical path OP1 extending from the superimposing lens 35 to a first liquid crystal display panel 61r. Thus, the F number of an illumination system 30 associated with blue light can be controlled with high degree of freedom, and the number of lenses constituting a color separation and light guide system 40 and the illumination system 30 does not increase. Moreover, the incident angle of illumination light does not become large around the first liquid crystal display panel 61r, and thus the telecentric characteristics of the illumination system 30 associated with blue light can be secured.

Abstract: A color laser printer 10 compares a pervious printer, which a toner cartridge 40 has been attached to immediately before attachment to the current printer, with the current printer. In the case where the previous printer is different from the current printer, the color laser printer 10 obtains setting information on the previous printer, which is stored in a storage element 50 of the toner cartridge 40, and applies the obtained setting information for the current printer. The various settings in the previous printer are thus turned over to the current printer, when the toner cartridge 40 is detached from the previous printer and is attached to the current printer. This arrangement ensures smooth printing operations without requiring any troublesome settings to use the current printer.

Abstract: Prior to the execution of a printing operation, a print preparatory operation is conducted only on a priority developer cartridge out of the plurality of monochromatic developer cartridges mounted to the developing unit thereby bringing the cartridge into a printable state. Therefore, the print preparatory operation is completed when the print preparatory operation on one (equivalent to a “priority cartridge” of the invention) of the developer cartridges mounted to the developing unit is terminated. Hence, the apparatus may be placed in the printable state in a short time so that the print preparatory operation is prevented from compelling a user to wait needlessly long and that waiting time of a user may be shortened.

Abstract: The relationship L1?V(F1×?11/2×100) is satisfied where a transmission path length between the interface 1 and the timing controller is L1, a propagating speed of electromagnetic waves in a vacuum is V, a frequency of a signal transmitted between the interface and the timing controller is F1, and a comparative dielectric constant of a transmission path medium between the interface and the timing controller is ?1. The relationship L2?V(F2×?21/2×100) is satisfied where a transmission path length between the timing controller and the signal driving portion is L2, a propagating speed of electromagnetic waves in a vacuum is V, a frequency of a signal transmitted between the timing controller and the signal line driving portion is F2, and a comparative dielectric constant of a transmission path medium between the timing controller and the signal line driving portion is ?2. Thus, the occurrence of EMI noise can be suppressed, and the implementation cost of a display apparatus can be reduced.

Abstract: In a communications network where multiple shared risk link groups are formed by links having a common risk, unreserved bandwidths are defined corresponding to all SRLG's and a maximum bandwidth of each link is set as an initial value of each of the defined unreserved bandwidths when a working path or a protection path of “1+1” or “1:1” recovery type is requested. When a protection path of “shared” recovery type is requested, unreserved bandwidths are defined corresponding to the SRLG's to which the links of its corresponding working path belong and a maximum bandwidth of each link is set as an initial value to each of the defined unreserved bandwidths. The bandwidth of the working or protection path is subtracted from each of the unreserved bandwidths. The request is rejected if a minimum of the subtracted values is smaller than a threshold.

Abstract: A color laser printer of the invention identifies each object image to be printed as a color image or a monochromatic image. When the object image to be printed is identified as a color image, the control procedure of the invention rotates a developer unit with multiple color toner cartridges to sequentially move positions of the respective color toner cartridges to a development position and forms respective color toner images on a photoreceptor. When the object image to be printed is identified as a monochromatic image, on the other hand, the control procedure fixes a specific toner cartridge filled with black toner to the development position and forms a black toner image on the photoreceptor. A counter counts up consecutive monochromatic printing operations.

Abstract: Prior to execution of a printing operation and in parallel with a warm-up operation of the apparatus, a print preparatory operation is conducted only on selected cartridges of cartridges mounted to a developing unit, thereby bringing the cartridge into a printable state. Therefore, even if the residual amount of toner in one of the selected cartridges runs short, the printing operation is allowed to continue by switching this cartridge to the next selected cartridge.

Abstract: Prior to execution of a printing operation, a print preparatory operation is conducted collectively on all developer cartridges mounted to a developing unit, thereby bringing all the developer cartridges into a printable state. Therefore, even if a residual amount of toner in the cartridge runs too low to continue the printing operation performed using one of plural cartridges mounted to the developing unit, the printing operation is allowed to continue by switching the cartridge to the next cartridge. Hence, a large volume of monochromatic prints may be produced in an efficient manner.

Abstract: Toner cartridges 32C, 32M, 32Y, and 32K have storage elements 33C, 33M, 33Y, and 33K mounted thereon to transmit information carried on electromagnetic wave in a predetermined frequency band. An information receiver transmitter unit 30 is located in a neighborhood of an end of a developer unit 23 with the toner cartridges 32C, 32M, 32Y, and 32K attached thereto to transmit information carried on the electromagnetic wave in the predetermined frequency band to and from a color laser printer 20. While the developer unit 23 is rotated to develop each color component image with a supply of toner from the corresponding one of the toner cartridges 32C, 32M, 32Y, and 32K, the information receiver transmitter unit 30 is controlled to write a cumulative toner consumption and a cumulative number of printed sheets into the corresponding one of the storage elements 33C, 33M, 33Y, and 33K.
