摘要： PROBLEM TO BE SOLVED: To shorten the cleaning time by switching one cleaning liquid supply means to cleaning of a blade and cleaning of a bank of ink transfer rollers with switching means. SOLUTION: In an initiation state, i.e., a state where a second cleaning nozzle 30 is directed to a blade 21, cleaning liquid 27 is spouted intermittently to the blade 21 from the second cleaning nozzle 30 in predetermined times. In the next place, the rod 34a of a first air cylinder 34 is forwarded so as to direct the second cleaning nozzle 30 in the direction of a distributing roller 13. By keeping this state, cleaning liquid 27 is spouted on the peripheral surface of distributing rollers 15, 16 from cleaning liquid 27 and, at the same time, cleaning liquid 27 is spouted intermittently on the peripheral surface of the distributing roller 13 from the second cleaning nozzle 30. Cleaning liquid 27 spouted on the peripheral surface of the distributing rollers 15, 16 transfers on each rotating roller of an ink device 3 to then be collected in a cleaning bath 20 as a waste liquid of ink. At this time, the blade 21 is cleaned in advance, so that a waste liquid of ink never flows in the downstream side of the blade 21.

摘要： PROBLEM TO BE SOLVED: To control the optical output by forming an error amplifier for controlling the forward current of a semiconductor laser and a current drive section for feeding a drive current corresponding to an emission command signal, as a forward current, to the semiconductor laser on one chip of an integrated circuit. SOLUTION: An optoelectric feedback loop 6 is formed by connecting a semiconductor laser 3 and a light receiving element 4 in loop while including an error amplifier 8. Output from the semiconductor laser 3 is monitored by the light receiving element 4 and the forward current of the semiconductor laser 3 is controlled such that the optical output is equal to an emission command signal IDA1 generated from a pulse width generating/data modulating section 2. A constant current source 7 functions to feed the semiconductor laser 3 with a forward driving current corresponding to an emission command signal IDA2 generated from the pulse width generating/data modulating section 2. Consequently, the optical output from the semiconductor laser 3 can be controlled basically by the sum (or the difference) of a control current from the optoelectric feedback loop 6 and the driving current from the constant current source 7. The modulating section 2 and the driving section 5 are integrated on one chip.

摘要： PURPOSE:To improve the labor saving and productivity by fitting ring-shaped parts having an opening such as a snap ring into a storing cylinder in an aligned condition. CONSTITUTION:The specified number of ring-shaped parts 1 are fitted in a random arrangement from the open end to an alignment bar 2 of small diameter which is rotatably supported by mounting a driving motor 4 and a reduction gear 5 on the base end side, and the alignment bar 2 is rotated. With this constitution, the ring-shaped parts 1 is rotated while being slidably in contact with the alignment bar 2, the alignment bar 2 is fitted in the opening part 1A, and stopped in the condition where the opening part 1A is located to the upper side of the alignment bar 2. Then, the ring-shaped parts 1 are shifted to a storing cylinder 11 by setting the guide section 6B of a connecting member 6 and a projecting rib 11A of the storing cylinder 11 as the positioning members.

摘要： PURPOSE:To prevent the missetting of a luminous level command signal by surge current at the time of power application and under unstable circuit conditions, by comparing the magnitudes of a constant potential and a potential of a power voltage minus a constant voltage, and generating a timing signal for generating a luminous level command signal, when the constant potential side s smaller. CONSTITUTION:A power voltage monitor circuit 9 compares the magnitudes of a constant potential and a potential of a power voltage Vcc minus a constant voltage, and judges whether or not the power voltage Vcc is higher than a specified potential. If the constant potential is lower, a timing signal generator circuit 10 is started. On the other hand, if the constant potential is higher, a specified command signal is outputted to a comparison amplifier 2 and a current transformer 7, and control is performed so that driving current may not flow in a semiconductor laser 3. Consequently, it becomes possible to drive the semiconductor laser stably without missetting caused by the variance of the power voltage and the changes of the surrounding temperature.

摘要： PURPOSE:To enhance the degree of preciseness in control of the forward current of a semiconductor laser by forming a comparative amplifier with a high impedance input part and a driving current converting circuit. CONSTITUTION:A comparison amplifier 1 is formed by successively connecting a high impedance input part 6 having an emitter follower, differential amplification circuit 7 and a driving current converting circuit 8. Consequently, the interterminal voltage of a capacitor C is changed by the differential current between the current Is corresponding to a light emission level instruction signal and the current Im corresponding to a light receiving signal, and the above- mentioned interterminal voltage is inputted to the differential amplification circuit 7 through the intermediary of the high impedance input part 6. As a result, the output of the differential amplification circuit 7 changes in proportion to the change of the interterminal voltage. In other words, the differential current is amplified. By passing the differential amplification circuit 7's output through the driving current converting circuit 8, the driving current (forward current) of an excellently controlled semiconductor laser 3, which becomes the desired luminous energy in proportion to the output of the differential amplification circuit 7, can be obtained.

摘要： PURPOSE:To reliably obtain the laser power of the desired light emission level by providing a first light emission level instruction signal forming circuit and a laser power adjusting circuit. CONSTITUTION:The forward current of a semiconductor laser 3 is controlled in such a manner that a light receiving signal and a first light emission level instruction signal are made equal by comparing the light receiving signal of a light receiving element 4 and a first light emission level instruction signal by a comparative amplifier 1. Also a current converter 2 outputs the preset current in accordance with the above-mentioned light emission level instruction signal so that the light receiving signal and the light emission level instruction signal will be made equal. The total current of the output current of the current converter 2 and the control current outputted from the comparison amplifier 1 forms the forward current of the semiconductor laser 3 to be controlled. The first light emission level instruction signal is formed and outputted by a laser power adjusting circuit 6 with which the laser output power is adjusted. This laser power adjusting circuit 6 is composed of a reference current setting circuit 7, a first light emission level instruction signal forming circuit 8 and a correction circuit 9.
