Filed: 1991-04-17
Abstract: PURPOSE:To prevent an input voltage short-circuiting when two switches are turned on simultaneously by providing short-circuiting prevention resistors, for a voltmeter corresponding to each of a plurality of input selection switches and then providing a warranty resistor between the prevention resistor and the switches. CONSTITUTION:When selection switches 1 and 2 are turned on simultaneously, an area between the first and second input voltages is not short-circuited since voltage short-circuiting prevention resistors 5-8 are connected in series between switches 1 and 2 and a voltmeter 9. Also, since the resistors 5-8 are connected to both a positive side and a negative side of both input voltages in series, the polarity of both input voltages can also be switched. ON state of the switches 1 and 2 is warranted by connecting contact switch warranty current supply resistors 3 and 4 between the switches 1 and 2. These resistors 3 and 4 prevent erroneous display due to resistor-division of the voltmeter 9, thus preventing short-circuiting of first and second input voltages event if the switches 1 and 2 are turned on simultaneously.

Abstract: PURPOSE:To enable an optical unit to adjust a light output independently by providing a constant voltage power supply section which supplies a constant voltage to a drive circuit connected to an external power supply, in a light-emitting element drive circuit of a laser printer. CONSTITUTION:A substrate 104 which becomes a drive circuit for an optical system such as a polygon mirror and a semi-conductor laser element 201 are assembled in an enclosure of an optical unit. On this substrate 104, a constant voltage power supply element 301 is mounted, and for instance, a 12V voltage is supplied from the outside through a connector 400 to supply a +5V constant voltage to each element such as a semi-conductor laser element 201 on the substrate from a terminal A and a GND terminal B. The semi-conductor laser element 201 consists of a semi-conductor laser chip 310 and a photodiode 311 which detects the amount of light energy of the auxiliary laser beam from the semi-conductor laser chip 310 and generates heat itself to stabilize its output. The semi-conductor laser element 201 is driven by a laser drive IC 300 and is subjected to the adjustment of the amount of light energy by a volume 320. Thus the light output need not be readusted when a light-emitting element drive circuit is incorporated in a printer, after the light output is is adjusted by the optical unit alone.

Filed: 1979-09-03
Abstract: PURPOSE:To ensure a wide-range adjustment of the picture quality, by integrating the input signal and then amplifying the integrated value to add it to the adder. CONSTITUTION:The input signal supplied from the input terminal 1 is supplied to the adder 6 via the differentiator 2 and amplifier 3, via the amplifier 5 and furthermore via integrator 8 and the amplifier 9 each. The picture quality adjustment terminal 4 is connected to the amplifiers 3, 5 and 6 each.

As a result, the soft videosignal can be possible up to the integral signal of the input signal although the sharp video signal is identical to that of the conventional circuit. In such way, the range of adjustment can be increased for the picture quality just by adding the integral circuit to the conventional circuit.
