Filed: 1989-11-16
Abstract: PURPOSE:To maintain high correcting ability even with a small number of erasure flags by storing one piece of erasure information temporarily for each classification and outputting erasure information of a necessary classification during the correction processing of a reinforced correction code processing means. CONSTITUTION:An erasure information control part 7 puts erasure flags, which are outputted when an error correction code processing part 6 is unable to make corrections, together into one erasure flag for every plural group data according to a constant rule and stores it temporarily, and outputs a necessary erasure flag when the reinforced correction code processing part 10 is in correction processing. For example, the erasure flags which are used for the correction processing of reinforced correction codes, recording positions on a tape are classified into four, i.e. upper and lower plus azimuth track sides and upper and lower minus azimuth track sides. Consequently, the high correcting ability can be maintained even with a small number of erasure flags for a practical continuous error such as the clogging of a head.

Filed: 1988-11-29
Abstract: PURPOSE:To improve safety and reliability of a machine by arranging a weight such that it is pushed up when a lid is closed and lowered through self-weight when the lid is opened, thereby pressing the lid and locking the lid in closed state when the machine is rised under closed state of the lid. CONSTITUTION:When an electronic typewriter is set horizontally and the hood 2 is closed, a weight 6 exists at the left end of an inclining groove 1b and presses an actuator 4a, thus turning a hood switch 4 ON. When the hood 2 is rotated in direction C, the weight 6 leaves a rib 2a and rolls to the right end of the groove 1b with self-weight, thus opening the hood 2 and turning the hood switch 4 OFF. When the hood 2 rotates to position 2', the rib 2a collides against the weight 6 and the hood pushes the weight 6 obliquely upward of the groove 1b thus moving the hood switch 4 gradually to a position where it is turned ON. If the hood 2 is standed on face B with the hood 2 being closed when the typewriter is not used, the weight 6 presses the arched left end section of the rib 2a and energizes the hood 2 in direction D, thus holding the hood 2 in closed state.
