Abstract: PROBLEM TO BE SOLVED: To obtain a maintainability of software and a good cost performance by executing in real time at a time when an input and output apparatus.device is in a waiting state for response or at every specified time interval while mutually changing to the other program. SOLUTION: A real time OS 12 does not execute a task waiting for event as a waiting state and executes each task in an executable ready state in time- sharing followed by a determined priority order. When a printing instruction is received from a printing controller, a printing process task 4 starts a paper feed process task 5 and a paper discharging process task 6 in a proper timing and executes tasks in the ready state in time-sharing. Thus in a multi-task control by the real time OS 12, when a certain task goes into an event waiting state, a CPU 13 does to execute the task by keeping the task in the waiting state until the event occurs and executed other ready state task.

Filed: 1989-04-27
Abstract: PURPOSE:To absorb the looseness of tape tension during taping, and to stabilize the state of the winding of a tape by charging a push having a hole, into which the detent pin of a tape holder is inserted, into a guide groove formed to a body of revolution, to which the tape holder is installed, so as to be able to be to some extent followed up along the guide groove to the rotation of the tape holder and giving the energizing force through a steel ball by a spring in the direction that the tape is given tension. CONSTITUTION:When a tape 2 is pulled out in the direction of the arrow 19, a shaft is turned in the direction of the arrow 20 by tension. Since a detent pin is also revolved together with the shaft at the same time, a push 16 is also moved along a guide groove 3a. Since steel balls 18 brought into contact with the push 16 are pushed in the direction opposite to the arrow 20 by a spring, the push 16 is pressed by the steel balls 18 even when the tape 2 is loosed slightly, and the tape 2 is pulled in the direction opposite to the arrow, thus preventing the looseness of the tape 2.
