摘要： PURPOSE:To ease greatly the positioning accuracy required for the deletion by identifying in terms of image through the reading unit that the character has been deleted from the character code part and then generating the delete code. CONSTITUTION:The delete type composed of character part 1a and code part 3 (rectangle of width W X length l) is used, and the shape of part 3 is identified easily from dot code 6 of normal print character 1 and reference mark TM through the reading unit. The shape of the mark is decided at delete mark decision circuit 10 via continuity 8 and 9 in the X and Y directions, and this mark shape is compared with the reference delete mark memorized previously to decide (10) the deletion mark. Then the operation of code identification circuit 7 is stopped, and the delete code (all marks) dm is generated 12 to deliver character code D through the OR gate. Thus, the deletion of the character code can be decided by the presence or absence of the mark existing at the code part and in the reference shape, thus eliminating the process to print the dots in an accurate piling.

摘要： PURPOSE:To prevent light from being incident on the reverse surface of a photodetecting element and obtain a high-precision device which is easily manufactured by providing a means which converges luminous flux in a path through which light from a light emitting element travels to a pressure reception surface (reflecting surface). CONSTITUTION:The pressure sensor consists of a lens substrate 1 and a substrate 8 by forming the reflecting surface by vapor-depositing aluminum, etc., on a polyester film as the pressure reception surface 1 over one side, and providing a flexible layer 2 of light-transmittable silicone rubber, etc., and then a glass substrate 4. The light emitting element 7 is provided to the substrate 8 and a lens 10, etc., are provided to the substrate 11 so that light travels while converged. The light from the light emitting element 7 is converged by the lens 10 on a focus O and incident on a photodetecting element 3 through the pressure reception surface 10. At this time, even if pressure P is applied to the pressure reception surface 1 and the flexible layer 2 varies in thickness, the light travels from the focus O, so the light is incident on only the surface of the photodetecting element 3 and never strikes the reverse surface. Thus, the luminous flux means is provided, so reflected light incident on the reverse surface of the photodetecting element is prevented and the pressure is detected with high precision.

摘要： PURPOSE:To prevent the procuction of reactive power and to improve the quality of recording by controlling the applied power corresponding to the image signal. CONSTITUTION:X bits are picked out from both ends (change points of white/black signals) of each black signal component Y1, Y2, Y3, in which image signals (a) continue, and are energized as image signals (b-1) at the time T1 in the energizing time Ta. Next, X bits are picked out from both ends of each black signal component Z21, Z31, except ones energized as the image signal (b-1), and are energized as image signals (b-2) at the time T2. After this, the operation is performed in the same way until the black signal component is made none. In this way, the image signal (a) is energized as five signals of (b-1)-(b-5) at T1-T5, and respective feeding times are controlled so that Tb-1>Tb-2>Tb-3>Tb-4>Tb-5. As a result, the applied power to the continuous black data can be reduced as it approaches to the central part.

摘要： PURPOSE:To reduce the optical noise of a semiconductor laser on the basis of a method simplifying optical fine adjustment easily by detecting the generation of the optical noise of the semiconductor laser through a photodetecting element and displacing the semiconductor laser finely in the direction of an optical axis. CONSTITUTION:The variation (noise) of an optical output from the semiconductor laser 1 is detected by the photodetecting element 10, only the variation is amplified by an AC amplifier 11 and inputted to a driving circuit 12 and a piezo- electric element 13 is driven by the output of the circuit 12 to displace the semiconductor laser 1 finely in the optical axis direction. Since the optical noise is slightly separated from the distance (the length of a resonator) of the generation of optical noise in accordance with the fine adjustment of the distance between the semiconductor laser 1 and a medium 7 on a disc 6, the optical noise is suppressed.

摘要： PURPOSE:To secure the follow-up of a light beam to tracks over a wide range by giving a rough shift to a pickup in response to the DC component level of a tracking error signal. CONSTITUTION:A pickup 1 has a fine shift mechanism 5 which has a continuous follow-up of a light beam to tracks in a microrange, and this pickup 1 is shifted intermittently by a rough shift mechanism 12 in the radius direction of a recording medium and in a wide range equal to the radius. Then the light beam is made to follow up a track only by a fine shift mechanism 5 when the DC component level of a tracking error signal is within a prescribed range. This follow- up action is continued by the mechanism 12 when said DC level is out of the prescribed range, and at the same time an intermittent shift of the pickup 1 is started by the mechanism 12. This intermittent shift is discontinued when the DC component level reaches the prescribed value. Thus it is possible for the light beam to follow up continuously the tracks over a wide range.
摘要翻译：目的：通过响应于跟踪误差信号的直流分量电平，大幅度地转移到拾取器，以确保光束对大范围的跟踪。构成：拾取器1具有细微的移动机构5，该移动机构5具有光束连续跟随在微区中的轨迹，并且该拾取器1通过粗略移位机构12在记录介质的半径方向上间歇地移动，在相当于半径的宽范围内。然后，当跟踪误差信号的直流成分电平处于规定范围内时，使光束仅通过微调机构5跟踪轨道。当所述直流电平超出规定范围时，该机构12继续进行后续动作，并且同时由机构12开始拾取器1的间歇移动。当直流分量水平达到规定值。因此，光束可以在宽范围内连续跟踪轨道。

摘要： PURPOSE:To enhance the controllability of the pattern input device with a simple constitution, by securing a conduction between the adjacent linear conductor and linear resistor at the writing point and via the pressure-sensitive conduction sheet and then detecting the positions in the directions of the length and the right angle each. CONSTITUTION:The output of the counter 30 turns on successively the change-over switches S1-Sn via the decoder 31 and then drives successively the driving lines LD1-LDn. At the same time, the voltage V1 and V2 generated across the detection lines LS1-LSn formed with the linear resistors and via the load resistances RL1- RL2 are applied to the analog adder 32 and the analog divider 33. Thus the position in the direction of length is detected to be supplied to the differential amplifier 34. Now if the driving line LDi is driven via the change-over swich Si, a conduction is secured between the lines LDi and LSi at the writing point P and via the pressure- sensitive conduction sheet. And then 1 is delivered from the level detector 36 to be applied to FF37. As a result, the operation of the counter 30 is discontinued, and the sample pulse is generated from the sampling pulse generator 40. And the position signals of the X and Y directions of point P are stored into the X and Y registers 41 and 42 each.
