Title: Pitch error correcting method
Inventor: MURAMATSU YASUO
IPC: G05D3/12
Filed: 1987-03-11
Abstract: PURPOSE:To correct the pitch errors by securing a ring structure for a servo processor memory to write the pitch error correction information into this memory and then extracting successively said correction information in the moving direction of a machine to rewrite the end area of the ring structure. CONSTITUTION:A positioning device consists of a main processor 1, a memory 2, a servo processor 3 and a memory (pitch correction information memory) 4. The correction information is set opposite in 1:1 to the position on the machine stroke. When the address of the memory 4 is replaced in a shift on the machine stroke for compensation of the difference of memory capacity between both memories 1 and 3, the information 9 on the memory 2 is rewritten with width 6 of the memory 4 based on the pass through a certain point 7 (or 8) and transferred to an address 10 of the memory 4. In this case, the information 9 is actually sent to a physical memory address 11 owing to a ring structure of the memory 4. Thus the rewriting timing has the hysteresis characteristics. The memory width 6 to be rewritten is selected properly so that a pitch error can be corrected with no limit of capacity of the memory 4.

Abstract: PURPOSE:To make a printable range uniform regardless of the size and type of printing form by providing a constitution in which a continuous form is detected by a cutform detection device, if the non-presence of the continuous form is detected by a continuous form detection device, and the continuous form is detected by the continuous form detection device, if the presence of the continuous form is detected by the continuous form detection device. CONSTITUTION:If a switching lever 17 is switched to the continuous side after the setting of the continuous form 1 to a pin tractor wheel unit 3, a control circuit section 21 outputs a switch command signal to a switching mechanism 9 and consequently, a paper feed roller 13 is set apart from a platen 7. Then if the continuous form 1 passes a paper end switch 5, the control circuit section 21 connects the switch command signal to the switching mechanism 9 to cause the form to come in contact with the platen 7. After this, the form is transported to a printing head 15 as wound around the platen 7, and printed by the printing head 15 until the form passes a paper end switch 11. In addition, if the switching lever 17 is switched to the cutform side, the paper feed roller 13 is set tightly close to the platen, then the cutform 19 is transported by the paper feed roller 13 and printed by the printing head as wound around the platen 7. Thus the printable range can be made uniform.

Filed: 1980-04-30
Abstract: PURPOSE:To read an original accurately by reading the quantity of light from a fluorescent lamp by an image sensor before reading the original, by storing said quantity in a storage after converting it in digital, and by making a shading compensation on the basis of the information from the storage in reading the original. CONSTITUTION:Before the start of a read, the quantity of light of fluorescent lamps R1 and R2 reflected at a white part on original OR is obtained by CCD and stored in storage M via gain variable amplifier AMP and A/D converter AD. The gain of AMP at this time is fixed to a prescribed value and then switch SW is closed to negatively feed back the output of storage M to AMP via D/A converter DA and LPF, to control the gain. The amplification factor is increased corresponding to the left and right ends of lamps R1 and R2 where the quantity of light is small and increased corresponding to the center where the quantity of light is large to compensate change of the readout signal uniformly. Thus, disadvantages of a mechanical shading correcting method are eliminated and fluctuations of the quantity of light due to fluctuations of temperature are also compensated.
