Title: Cam gear
Inventor: KOGA NOBUYUKI
IPC: F16H27/08
Filed: 1990-11-19
Abstract: PURPOSE:To broaden the degree of freedom of the designing of a cam factor by forming at least one tooth situated on the end part of a tooth part that has a toothless part, in such a way that the diameter of its tip circle is less than that of a tip circle of the other tooth, and that the tooth is formed like a pointed projection. CONSTITUTION:A tooth 5 situated on the top front of the rotational direction of three partial tooth parts 4 of a cam gear 1, and a tooth 7 other than a tooth 6 situated next to the tooth 5, are of general shape, and the tooth size of a first tooth 5 is slightly shorter than that of the other tooth 7, and its point part is formed like a pointed projection, while the diameter of a tip circle 8' is slightly shorter than that of a tip circle 8 of the other tooth 7. Both side surfaces 9 of a point part 5a of the first tooth 5 whose top surface is pointed, are shaped like a chevron. While a second tooth 6 is almost the same as the other tooth 7, its point part 6a is pointed projection, and its both side surfaces 19 are also shaped like a chevron. The degree of mutual interference thus becomes very small, and since the engagement of both of the teeth is facilitated, an elastic part is not needed to be provided on the tooth part.

Title: Printer control method
Inventor: KITAHATA KAZUO
IPC: B41J11/42
Filed: 1988-12-12
Abstract: PURPOSE:To reduce a wasteful halt time of a CR motor to improve a real printing speed of a printer by a method wherein in a printer having a paper existence detection means, the acceleration, constant-speed, and deceleration action of a PF motor is conducted in a lapped manner with the deceleration, halt, and acceleration time of the CR motor. CONSTITUTION:Whether or not a paper is present is judged by a signal from a PF detector 2. If paper is present, the acceleration of a PF motor is started simultaneously with the deceleration start of a CR motor. The CR motor has been in a halt while the PF motor is in a constant speed state. The acceleration of the CR motor is started at the time when a preceding time elapses, which is obtained by subtracting the acceleration time of the CR motor from a time required for the PF motor from the deceleration to a stop. Once the absence of paper is judged, an override amount is assumed to be a residual override amount and compared with a next paper feed amount. If the paper feed amount is smaller in the comparison, a value obtained by subtracting the paper feed amount of this time from the residual override amount is assumed to be a next residual override amount. On the other hand, if the paper feed amount is larger, paper is fed by the residual override amount without driving the CR motor.
