Abstract: PURPOSE:To reduce power consumption and enhance printing accuracy, by providing the first gear driven either directly by a spacing motor or through engagement with a toothed plate concurrently with a movement of a carriage, and a gear mechanism for driving a ribbon-feeding system in one direction in conjunction with the first gear. CONSTITUTION:With the first gear 14a rotated by a spacing motor 13, its rotation is transmitted to a driving gear 20a through internal gears 21a, 21b, and is transmitted to a driving gear 20b through a shaft 17, a gear 14a and an internal gear 21c. In this case, driving gears 20a, 20b are rotated in opposite directions to each other. The driving gears 20a, 20b are connected to a shaft 22 through a one-way clutch 20f, and transmit only a counterclockwise free rotation to the shaft 22 in a limiting manner. Therefore, the driving gear 20b rotated clockwise is rotated idly, and only the rotation of the driving gear 20a which is rotated counterclockwise is transmitted to the shaft 22 to rotate the latter counterclockwise, thereby driving the feeding system in a ribbon cartridge 16.

Title: Distance detecting apparatus
Inventor: JINNO TSUTOMU
IPC: G01B7/00
Filed: 1994-07-29
Abstract: PURPOSE:To provide a distance detecting apparatus, which detects the distance between two points without malfunction with regard to distance detecting apparatus for detecting the distance between a transmitter and a receiver based on the strength of magnetic field. CONSTITUTION:Driving circuits 4, 5 and 6 drive coils 1, 2 and 3 with the modulating signals, which are turned on/off with the signal having the second frequency lower than the first frequency that is the frequency of an AC current. A rceiver 9 detects the component of the second frequency from the detected AC magnetic field and detects the fact that the distance to a transmitter 8 becomes a specified value or more when the detected level is less than the specified value. Since the central axes of the coils for generating the magnetic field are arranged in three-dimensional directions, the magnetic field, which is generated by at least one of three magnetic-field generating coils, is most strongly detected with the receiver 9. Therefore, the change in coupling caused by the direction of the transmitter 8 and the receiver 9 is less, and the distance between the transmitter 8 and the receiver 9 can be accurately detected.

Abstract: PROBLEM TO BE SOLVED: To increase accuracy of improper position winding frequency data by computing improper position winding frequency data specifying the improper position of a winding body with winding frequency data and improper position designation data inputted. SOLUTION: An improper position winding order computing means (1) 24 computes improper position winding frequency data specifying the improper position of a winding body by inputting winding frequency data a winding frequency measuring means 29 outputs and improper position designation data an improper position designating means 30 outputs.

This compensation is suitable for a case where a web winding position and an inspecting position with an inspection instrument or the like are separated from each other. The improper position winding frequency data are the data corresponding to the winding frequency if an improper condition is detected.
