DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An ink pad case detaching mechanism of a recorder according to the present invention can easily move an ink pad case having a rotating shaft fitted to a bearing of a recording cart by operating a lever from the bearing in a direction perpendicular to the rotating shaft. The ink pad case can be easily attached and detached in the recording cart because the ink pad case can be inserted from above. Further, even if the recording pen is in contact with the ink pad, the ink pad case can be detached upward only by operating the lever, so that the ink pad case can be easily replaced without soiling the hands. Further, since there is no complicated mechanism in the recording cart, the width of the recording cart can be made narrow and thin, and the recording cart can be moved close to the side wall of the recorder, so that the recording cart can be moved over the entire width of the recording paper. .

The ink pad case of the present invention has a rotation shaft projecting from the center of both side walls of a storage portion for storing an ink pad, a guide provided on one of the front and back sides of the side wall, and a pair of guides on the inner surface of the recording cart. Since the projections are implanted, the ink pad case can be easily and reliably attached and detached from the recording cart. In this ink pad case, the rotating shaft is extended on both sides at the center and the shaft end is fitted to the bearing of the recording cart, so that it can be easily pulled up from the open portion of the bearing, as in the conventional case. There is no need to pull out the rotary shaft together with the ink pad case from the inside of the recording cart and then slide the ink pad case in the longitudinal direction of the rotary shaft.

A shaft is rotatably arranged on the left and right side plates of the recording cart below the axis of the ink pad case, a lever portion is provided outside one of the side plates, and at a position below the ink pad case, A push-up member is provided with a slight gap from the ink pad.

The ink pad case of the present invention is
The rotating shaft and the ink pad can be integrally formed, and the portion other than the portion in contact with the printing pen is not exposed. Rotate the ink pad case to the initial operating position and stop at the take-out position for replacement with a new ink pad case from the recording cart, and then move to the exchange position where the recording cart has a removable space, By operating the release lever of the ink pad case, the ink pad case can be removed and easily taken out. In addition, the mounting is guided by the guide of the recording trolley and can be easily mounted on the bearing of the recording trolley, so that the fingertip and the like can be prevented from being stained during the replacement work of the ink pad case.

Further, according to the ink pad case attaching / detaching control method of the present invention, when the ink pad case exchanging mode is selected, the ink pad case can be attached / detached in the vertical direction of the rotation axis by the ink pad detecting means and the ink pad case controlling means. By rotating the recording carriage in the recording paper width direction to a position where the ink pad case can be easily attached and detached, the detaching operation can be simplified. The position of the recording cart is controlled by pulse control using a pulse motor and an encoder. In addition, when replacing the ink pad case, the recording cart is moved in the width direction of the recording paper, so that the detachable replacement position can secure a large space around the recording paper. Since the ink pad case is set at the open position of the bearing, the ink pad case can be easily taken out without being bothered by taking out the ink pad case.
