Title: Highly precise positioning device
Inventor: TOKIDA HARUHIRO
IPC: G05D3/12
Filed: 1986-07-09
Abstract: PURPOSE:To highly precisely determine the stopping position of an object to be controlled, by providing a stoppage controller between a reversible counter (1st comparison means) and DA converter and comparing a set value with the phase of the two-phase signal of a rotary encoder by means of the 2nd comparison means is the controller. CONSTITUTION:An encoder 8 gives the pulses B1 and B2 of two pulses having a phase difference of 90 deg. to one end of a reversible counter 2 through a stoppage controller 3 and encoder interface 10 in the order of phase. The controller 3 is provided with a data selector 11, a magnitude comparator 12 as the 2nd comparison means, and zero detecting circuit 13. The data selector 11 stores three patterns of control signals G. The magnitude conparator 12 compares a set value H with the combined value of the signals B1 and B2 and, only when the count value C of the reversible counter 2 is zero and a compared result of the CPU 12 is coincident, the selector 11 outputs a control signal CG for stoppage to a rear-stage control system. As a result, the stopping position, namely, the range of C=0 of a motor 6 is divided into four ranges and the stopping position is determined in one of the divided ranges. Therefore, positioning accuracy is improved four times.

IPC: G06F3/12
Filed: 1988-06-30
Abstract: PURPOSE:To make it possible to judge whether the stop of printing is caused by waiting for reception of a line end command or by discontinuation of data transfer, by giving an alarm on the discontinuation of the data transfer when an interval of reception of print data exceeds a prescribed time in a state wherein the result of judgement of not being the line end command is stored. CONSTITUTION:CPU 11 stores received print data in a reception buffer 16. When the received print data are a line end command, it executes printing of one line on the basis of the print data. When the print data can not be received, on the other hand, the CPU 11 makes a timer 20 start and measures an interval of reception of the print data while comparing a timer value (time) thereof with a prescribed time set beforehand. When the data are not transferred from a host device 22 notwithstanding an interface circuit 15 being in a ready state, for instance, in a state wherein a mid-line flag stored in a flag area 14a of RAM 14 is ON, and the reception interval measured by the timer 20 exceeds the prescribed time, the CPU 11 gives an alarm on the discontinuation of the data transfer by means of a buzzer, for instance, through an alarm generating circuit 21.
