Abstract: PURPOSE:To enable to judge the depressed position surely, by using a few pressure sensing elements, by comparing the coordinate of the depressed position obtained through the operation of the partial press signal of the pressure sensing element depressed with the position information located on the key top position information memory. CONSTITUTION:A plurality of key tops 2 are displayed on the keyboard panel 1, and the pressure sensing elements DET1, 2, 3 are provided on different position under this panel 1. When an arbitrary key top 2 is depressed, the partial pressure signal produced to the elements DET1, 2, 3 is respectively amplified AMP1, 2, 3 and fed to the operation circuit OP after A/D conversion. Futher, the coordinate of the depressed position is operated at the circuit OP, this operation output and the key top position information stored in the key top position information memory MK are compered, and the depressed position is judged by it. Accordingly, it is not necessary to correspond the key top 2 and the element 3 by one to one, and the depressed position can surely be judged by using a few pressure sensing elements.

Abstract: PURPOSE:To reutilize waste ink by returning the waste ink generated by recovery operation and preparatory emission to an ink container in an ink jet recording apparatus. CONSTITUTION:An ink container capable of reutilizing waste ink generated by recovery operation and preparatory emission has an ink supply container and a waste ink storage container. By making both of the ink supply container and the waste ink storage container replaceable, waste ink can be reutilized. Further, by arranging ink supply and waste ink storage parts in the ink container in many stages or a plurality of stages, waste ink can be reutilized by one ink container. Therefore, waste ink discharged and discarded heretofore by the sucking operation of a recovery system can be reutilized.

Abstract: PURPOSE:To enable the miniaturization and cost reduction of a printing recording apparatus by providing the gliding control member of a member to receive recording to the body of the printing recording apparatus used on a table so as to be capable of being received in said main body in a detachable manner. CONSTITUTION:The supply port 2 of a member 4 to receive recording and the discharge port 3 of the member 4 to receive recording are provided to a printing recording apparatus 1 and the member 4 to receive recording is inserted in the supply port 2 at the time of recording operation. The printing recording apparatus 1 becomes a state possible in recording operation when an operation switch 6 is operation and receives a printing command from a computer to perform printing recording on the member 4 to receive recording. The member 4 to receive recording is discharged from the discharge port 3 after recording to fall and strikes against the accessory member 5 of the printing recording apparatus to be arranged and accumulated at a predetermined position. At this time, when the accessory member 5 is not arranged, the member 4 to receive recording is not accumulated at the predetermined position by a gliding phenomenon to scatter. The accessory member 5 is attached to the product containing the printing recording apparatus 1 or provided to the printing recording apparatus in a detachable manner.

Abstract: PURPOSE:To accurately mount an absorber by considering the swelling rate and to accurately hold the dimensional accuracy after swelling by providing a projecting strip on the lower surface of an upper plate of a supporting frame, and employing a structure that the absorber of ink holds swelled state. CONSTITUTION:Ink absorbers 44-47 that cover head elements of bubble jet unit (BJU) 35-38 are contained in a cap 34. A projecting strip 50b is projected downward on the bottom of the upper surface plate 50a of a supporting frame 50, and the absorbers 44-47 are mounted. The ends of the absorbers are intruded to the inside from the edge of the plate 50 between the frame 50 and a throttling plate 51 to the degree that the strip 50b is slightly contacted. When ink is absorbed in this state, the absorbers 44-47 swell up, and the strip 50b intrudes into the absorbers 44-47. The projecting amount at this time is accurately controlled in the size by the swelling rate to freely perform a throttling work and ink absorbing action.

Abstract: PURPOSE:To keep stable stacking state by disposing a projecting portion at a position biased to the open side of the longitudinal central portion on the base of a stacking portion where recorded recording sheets are stacked, so that the stacked recording sheets are leaned against the side opposite to the open side. CONSTITUTION:After recording by a printer 10, the recorded recording sheet is guided to an upper sheet feed roller 130 and an upper pressure roller 140, separated from the roller 130 by a separationn plate 142, and then stacked on a stacker 6 through a paper guide 145 and a stacker roller 150. In the stacker 6, if a projecting portion 160 is formed a little to the front F of the longitudinal center of a recording sheet P, that is, the center of gravity, the stacked sheets P are leaned against the back B of the stacker 6. Accordingly, the stacked recording sheets are biased to the front by a shock caused by opening and closing a storing portion 2, so that when a stacker door is opened, the recording sheet will not come down from the open portion.

Abstract: PURPOSE:To exactly supply ink to ink-consuming portions such as an ink jet head, etc., by providing a small chamber of a width wider than an introduction tube and also of a length enough not to be touched by the tips of the introduction tube and also of a needle in the sealing portion of a cartridge type ink container. CONSTITUTION:A sealing portion 102 is provided with a small chamber, and the inner wall on the side facing at least the ink-introducing means of the small chamber into which a needle 106 is thrust and the tip of an introduction tube 103 are kept at an interval enough to prevent the contact of the needle tip with the tip of te introduction tube even when the needle is thrust. When the ink- introducing means is thrust into the sealing portion 102, the blocking of ink path and interruption of ink passage by narrowing of the ink path can be avoided even when the direction and center of the ink-introducing means are deviated. Since ink can be sufficiently supplied when connected with the ink jet head, for example, the stable discharge of ink is made possible all the time.
