Title: Recorder
Inventor: ISHIJIMA YOICHI
IPC: B41J2/32
Filed: 1990-02-17
Abstract: PURPOSE:To eliminate confirmation of image information after an ink sheet is used and to maintain its secret by heating recording agent remaining on the sheet after recording. CONSTITUTION:A recording agent is heated to be transferred at a position where a thermal recording head 1 is disposed at a position of a pixel corresponding to image information in synchronization with the movement of an ink sheet 2 and a material 3 to be recorded. In this case, a cleaning head 4 is heated over the entire width of the sheet 2 to all melt the agent remaining on the sheet 2 by the heat and to transfer it to a cleaning roller 5. After the information is ended to be recorded, the recorded material 3 is removed from a recorder. Accordingly, since all the agent is transferred from the sheet 2 used for recording, inverted image information cannot be read.

IPC: B21C47/02
Filed: 1984-02-28
Abstract: PURPOSE:To form a functionally excellent wind terminal wire by pulling out wire in front of holding position to centrifugal direction side holding the wire to allow free pulling out immediately before the terminus of winding and thereby giving linearity to the wind terminal wire. CONSTITUTION:A welding wire 1 in which desired cast is formed is held by a holding roller immediately after stopping. The wire 1 just before wind terminal wire 1g is held by a roller 4b from the center side of cast radius and by a roller 4a from centrifugal side of cast radius to allow free pulling out. When a pulling out roller 5 is moved upward to the front position, the wire 1 is pushed up, and the wind terminal wire 1g is pulled out, and pulled out to centrifugal direction side from tangential direction of cast radius. When the pulling out roller moves further upward, the wind terminal wire 1g is brought into contact with peripheral face of the roller 4a and pulled out. That is, it is ironed while receiving cast opposite to the cast and becomes linear. When the wind terminal wire 1g passes through rollers 4, 5, it is wound on outermost peripheral face of a spool.

Abstract: PURPOSE:To enable mounting and dismounting to be performed through one operation by cooperatively turnably providing a pair of holder levers having key parts at one end, perpendicularly forcing a cassette to mounting face, holding the same through opening and closing of the levers and holding the position with position springs. CONSTITUTION:A pair of levers 21, 22a having key parts 21a, 22a1 at one end and end parts 21c, 22a2 at the other end are turnably provided by way of position springs 45a which assume stable position in two positions. These levers are cooperated by connectors. While a cassette is not mounted, both levers 21 are held open. When the cassette 20 is perpendicularly inserted to the mounting face, it contacts the end parts 21c, 22a2, thus turning both levers in the mutually inwardly closing directions. On this way, the position springs 45 slowly move from the first stable position. When they exceed dead point, the levers 21, 22a are turned by the force that the springs take the second stable position, by which the end parts are slide contacted, guided and forced in. The cassette 20 is then held by a holder 51a.

Abstract: PURPOSE: To prevent a developer from flocculating near a toner regulation part by sticking magnetic toner onto a developer carrying and supporting means, by producing a moving magnetic field around a developer-amount regulating means.  
     CONSTITUTION: When a magnet roller 14 rotates as shown by an arrow, magnetic toner 16 sticks on a sleeve 13, and is carried on the sleeve 13 in the opposite direction to the arrow by the magnetic force of a magnet roller 14.
