Patent JP-H0375980-A (JP)
Title: Optical character reader
Inventor: SHIMANOE YASUHIRO
IPC: G06K9/20
Filed: 1989-08-18
Abstract: PURPOSE:To automatically eliminate dust on the read surface and to exactly execute read by bringing a read shaft to one rotation, when it is detected that paper is gone, and cleaning the outside peripheral surface. CONSTITUTION:Data on paper 2 carried onto a read surface 12a is read by a read part 17. When this read operation is repeated, and it is detected by a sensor 3 that the paper 2 on a hopper table 1 is gone, a motor 13 starts its rotation, and a link plate 15 rotates as one body with a read shaft 12. In this state, when a sensor 16 detects a notch part 15a, the motor 13 stops and opposes the read part 17. During this time, a cleaner 20 is brought to slide contact with the outer peripheral surface of the read shaft 12, and eliminates dust, etc., on the read surface 12a. In such a way, it becomes unnecessary to execute cleaning by an operator, and read can be executed exactly.

Title: Apparatus for taking up correction ribbon
Inventor: HANABUSA TADASHI
IPC: B41J33/18
Filed: 1985-09-27
Abstract: PURPOSE:To eliminate the wasteful use of a correction ribbon by preventing the excessive taking-up of an unused part, by providing the take-up reel of the correction ribbon always in contact with a feed gear by a spring through a lever. CONSTITUTION:A take-up reel 25 is pressed to a feed gear 19 through the revolving lever 24 drawn by a spring 23. At the time of correction in this state, a feed lever 5 is driven and a correction ribbon 4 is moved to a correcting position. When a feed ratchet 15 is rotated by one pitch, an intermediate gear 17 is rotated through a pinion gear 16 and the feed gear 19 is rotated through the gear 18 meshed with said gear 17. Because the one-pitch rotation of the feed gear 19 accurately is equivalent to one corrected character, the correction ribbon 4 is fed by one corrected character in a state almost pierced by the pawls 19a of the feed gear 19. By this method, the correction ribbon is always taken up by one corrected character even if the winding diameter of the correction ribbon increases.

Title: Disk memory controller
Inventor: WATANABE HIROKI
IPC: G06F3/06
Filed: 1987-08-28
Abstract: PURPOSE:To process on the presence and the absence of a defective sector at high speed by storing the contents of a flag indicating the state of a sector included in the ID (Identifier) part of the relevant sector. CONSTITUTION:A comparator COMP has a register stored in which address information designated from a host side is stored to compare the stored address information with the address information of the ID part read through a heard disk driving circuit HDD and detect a coincidence. A flag register FLAG stores flag information in the sector according to a coincidence detecting output formed by the comparator COMP and the flag information is decoded in a processing unit PU. When the flag of the presence of a defect is written in the sector and the reading error of the ID part is not detected, the presence of the defect in the designated sector is immediately transferred to a microprocessor CPU side. Thereby, the defective sector can be processed at high speed.
