摘要： A beam splitter is constructed from three light transmissive members formed of a glass or plastic that are bonded together to form a rectangular parallelepiped when taken as a whole. First and second light separating surfaces are formed at the bonding surfaces of the first and second light transmissive members and the bonding surfaces of the second and third light transmissive members, respectively. Accordingly, three light beams can easily be formed from a single beam of incident light.

摘要： By operating a mode switch, a user switches a laser light source module into one of five operation modes: a difficult detection/normal mode, a difficult detection/energy-saving mode, an easy detection/normal mode, an easy detection/energy-saving mode, and a photodetector mode. A ROM stores therein five combinations of data in one to one correspondence with the five operation modes. Each data combination includes data of drive frequency and data of ON duty ratio. When the user selects his/her desired mode, a CPU reads, from the ROM, one data combination of drive frequency and ON duty ratio that corresponds to the user's selected mode. The CPU applies the base of the transistor with a pulse drive voltage, whose repetition period and whose pulse width correspond to the read drive frequency and ON duty ratio. A laser diode oscillates in pulses with the drive frequency and ON duty ratio.

摘要： The transfer belt, for electrophotographic copying, has a basic layer with a surface layer of a coating fluid containing a solvent and at least one type of organic or inorganic fine particles which can be dispersed in the solvent, and at least one type of organic bonding agent which dissolves in the solvent. The fine particles are of an electrical insulation material. The fine inorganic particles are of silicate and the fine organic particles are of silicon which can disperse in the solvent. The solvent is organic. The base layer is elastic, with a number of elastic layers containing fluorine. The fine silicate particles have the same electrifying polarity as the voltage applied to the transfer belt. An Independent claim is included for an electrophotographic copier with a photo conductive layer with a toner image. The transfer belt carries the paper to the toner image on the photoconductor.

摘要： PURPOSE:To conduct paper tip-end treatment using a simple structure by a method wherein swing fins are operated after a specified length of paper is fed out, and there is conducted such control that the phase of the fins perfectly corresponds to the fold lines of the paper. CONSTITUTION:With the tip end of paper drawn into a delivery roller and with a specified length of paper fed out, a comparator 28 generates an accordance signal, which resets a flip-flop 17 and sets a flip-flop 18. A counter 22 counts PLS signals; with the count value equal to the output of a ROM25, a comparator 29 generates an accordance signal, and swing fins advance one step. Simultaneously, the counter 22 is reset, while a counter 23 is advanced by one count. The same operation is repeated until the counter 23 counts twelve, when ROM's 26 and 27 are selected sequentially.
