摘要： PURPOSE:To recognize whether transfer is interrupted or the printer is broken visually by displaying a receive state which is proportional to a receive frequency of a data of a printer by a method wherein segment lighting positions of a seven segment LED are varied in proportion to receiving speed. CONSTITUTION:A counter 30 is reset to zero by a reset signal 16, and a shift register 32 sets an initial value of an initial value setting circuit 31. For the initial value, only one bit among 6 bits is one and the rest are zero. The counter 30 counts a strobe signal 3, and outputs an output signal on the (n)th bit to the shift register 32. The shift register 32 shifts a data right by one pitch every time the output signal of the counter 30 varies, and shifts a position of a bit one right. A seven segment LED connected to the shift register 32 lights up at one and goes out at zero. Therefore, every time the data of the shift register 32 shifts right, a lighting position of the seven segment LED 39 is rotated in the order of (a), (b), (c).

摘要： PURPOSE:To provide a color video printer which automatically set input conditions of a video signal. CONSTITUTION:A computer 17 or 101 generates a test signal for entire-surface maximum brightness, a sequence generating circuit 45 and a mechanism control circuit 65 measures the horizontal scanning period and the number of horizontal scanning lines of the test signal, and temporary input conditions are found by arithmetic from the value. Under the input conditions, a test video signal is inputted to an image memory 60, an image area and a non-image area are measured from the input data, and the input conditions are calculated from the values. Since the input conditions can automatically be found, video signals of different standards can easily be switched and inputted.

摘要： PURPOSE:To forcibly remove a curl of recording paper by a method wherein an action for rewinding the recording paper to a position on which the paper is released from a restraint force is conducted when the paper continues in a waiting state, or a heat roller is mounted. CONSTITUTION:Recording paper is set so that a leading end 7a is disposed between front paper feed rollers 15a and 15b and rear paper feed rollers 16a and 16b. When a printing command signal is transmitted to a mechanism control circuit 314, recording is started. Optical sensors 36 and 38 constantly detect the presence or absence of recording paper 7. When the optical sensor 36 is ON and the optical sensor 38 is OFF, the recording paper 7 is fed downstream by a predetermined length by driving a feed roller 24 and stopped. If the optical sensor 38 turns ON, a recording action is performed. If it has been still OFF, an automatic paper feed is conducted.

摘要： PURPOSE:To prevent an objective lens from moving in directions other than specified as an AF direction (focusing direction) and a TR (tracking) direction by supporting the lens holder for the objective lens by elastic support materials which are arranged symmetrically about a support axis of turning. CONSTITUTION:The elastic members 5a and 5b, and 6a - 6d which have the same deflection characteristics are arranged symmetrically to support the lens holder 2, so the AF-directional components of spring forces of the respective elastic members 5a and 5b balance with an AF-directional driving force and the components perpendicular to the AF direction balance between the elastic members 5a and 5b which are arranged symmetrically to cancel each other. Further, when the lens holder is rotated in the TR direction, the elastic members 6a - 6d deflect symmetrically about the point of the support axis and the bending moment of the elastic members 6a - 6d balance with the TR-directional driving torque, so none of forces except in the AF and TR directions operates on the lens holder. Consequently, the objective lens 1 is prevented from moving except in the specific directions such as the AF direction and TR direction.

摘要： PURPOSE:To obtain a stably high-quality color image by a method wherein rollers which restrict or inhibit the movement of recording paper other than the movement in a feed direction and have surfaces applied with a special treatment are disposed on the upstream and downstream sides of a platen roller in the recording paper feed direction. CONSTITUTION:Recording paper 7 is pressed against a feed roller 24 by a pressure roller 25, thereby coming into contact with a large number of projected parts of the feed roller 24 to generate a frictional force. In this manner, the forming of a large number of contact parts discontinuous to the surface of the recording paper 7 ensures that the motion of the roller 24 is transmitted to the recording paper 7 without slipping. This contact state between the roller 24 and the paper 7 is similarly established at a contact part of a discharge roller 27 and the paper 7. If a density to be printed is varied in the width direction of the paper 7, the difference in a release force acting to the paper 7 causes the paper 7 to move in the width direction when an ink sheet 6 is peeled from the paper 7, thus resulting in a color deviation. In this case, however, the paper 7 never moves in the width direction because the recording paper 7 is clamped by the rollers 24 and 27 so as not to slip.
