IPC: B41J2/525
Filed: 1991-08-06
Abstract: PURPOSE:To provide an ink jet recording device by which stripes due to the feeding precision of a recording medium at a steam of printing areas do not generate, and stripes due to smear do not generate when duplicate printing is performed. CONSTITUTION:Ink tanks 4 for four colors and recording heads 7 are loaded on a carriage 5 which moves along a guide shaft 3.

Printing is done by performing major scanning by the rotation of the drum 9 under a condition in which the carriage 5 is moved to a printing position along the guide member 3 and stopped. When printing for one rotation of the drum is completed, printing is repeated by moving the carriage 5 along the guide member 3 by the printing width of the recording head. By arranging the recording heads so that they are shifted with their positional intervals one integer multiplications of the printing area, there is an effect that an image of high picture quality without generating smear at a seam of printing areas can be obtained.

Title: Switch
Inventor: WATANABE HIDETAKA
IPC: H01H9/02
Filed: 1990-08-23
Abstract: PURPOSE:To provide a blank cover commonly for different sorts of flash plates by forming the blank cover to reciprocate perpendicularly to the surface of an installation part. CONSTITUTION:For installing a switch to a first plate 12, a blank cover 21 is pressed by part of the first plate 12 to move toward a cover 3 against a spring 21c. The blank cover 21 is thus movable to reciprocate perpendicularly to the surface of an installation part 4, so a single sort of the blank cover 21 can be applied to different sorts of flash plates. Since an increase of one piece of the spring 21c causes almost no cost increase, the production cost is reduced largely as a whole by using the blank cover 21 commonly. By using the blank cover 21c commonly, troubles such as incorrect part preparation or the like are reduced.

Title: Automatic paper-supplying device for printer
Inventor: OZAWA HIDEAKI
IPC: B41J13/10
Filed: 1983-11-25
Abstract: PURPOSE:To eliminate the need for a motor used exclusively for a paper-supplying roller, by a method wherein a paper-supplying roller is rotated through a clutch by rotating a platen by a motor to perform a desired paper-supplying operation, and then a clutch is turned OFF. CONSTITUTION:When a controlling cam 97 stands by at a fixed position, a clutch spring 91 having an engaging part 92 engaged to an arcuate cam surface 100 slackens a clutch sleeve 88, thereby releasing the connection of the sleeve 88 and a paper-supplying roller shaft 21. When the cam 97 is rotated clockwise by rotating an intermediate gear 75, the engagement of the cam surface 100 and the engaging part 92 is released, the spring 88 and the roller shaft 21 are connected to each other by the spring 91, and are rotated as one body. When the cam 97 is rotated about 1/3 of a revolution, the cam surface 100 and the engaging part 92 are engaged again to each other, and the shaft 21 is stopped. Accordingly, there is no need for a motor used exclusively for the paper-supplying roller 41, and therefore, there arises no trouble due to mistuning, and the device is easy to handle.

Abstract: PURPOSE:To simplify constitution and to reduce the number of connection lines by outputting control signals for the necessary duration of each relay operation and duration shorter than the necessary duration of relay operation from a processor when a latching relay is driven and when a signal is led out of a signal source. CONSTITUTION:When the address in a control signal led out to the control line 5 of a processing circuit 1 coincides with the address set in an address setting circuit 8, the circuit 8 sends a H-level signal to a decoder 6 and a multiplexer MPX7. The decoder 6 drives a driving circuit 9 corresponding to the address in the control signal individually to operate the latching relay 10. At this time, a control signal which has duration longer than the time reguired for the operation of the relay 10 is led out of the processing circuit 1. The MPX7 selects one of signals from the signal source 20 and inputs it to the device 1 through an input signal line 18. At this time, the selection signal of the MPX7 having duration shorter than the necessary time of the operation of the relay 10 is led out of the device 1.
