Abstract: PURPOSE:To record a good image even on a medium to be recorded relatively low in surface smoothness, by successively performing the formation of an image to a transfer recording medium and the transfer of said image to the medium to be recorded by driving a take-up means at a constant peripheral speed. CONSTITUTION:A transfer recording medium 1 generating the change in its transfer characteristic by plural kinds of light energies passes a recording part 3 and a transfer roller 5 from a supply roll 3 to be taken up by a take-up roll 6 rotationally driven at a constant peripheral speed. In the recording part 3, the transfer recording medium 1 receives light energy from either one of fluorescent lamps 3c, 3d having different spectroscopic characteristics and a transfer image having a magenta or cyan color is formed by the heat generating element row 3b of a recording head 3a.

Title: Recorder
Inventor: SHIMADA MITSUHIRO
IPC: B41J13/22
Filed: 1985-09-25
Abstract: PURPOSE:To eliminate a slack of recording paper and enable said paper to be correctly adjusted to a recording startup position by allowing recording paper carrying means to be sent in the feed direction and commencing recording after reaching a home position when said paper is wound back by driving the recording paper carrying means in the backward direction. CONSTITUTION:A drum is allowed to rotate counterclockwise to wind back recording paper until the drum reaches a home position by giving a reverse rotational torque to a platen 1. This home position is identified by detecting a douser 30a provided on the internal surface of the drum 7 with the help of a transmission-type photosensor 30b. Even after the overrumming of the drum rotating counterclockwise beyond the home position, the drum is allowed to rotate only by required steps and then the drum 7 and platen 1 are stopped. Thus a slack of recording paper can be removed by once feeding the paper without actual processing and again winding back the paper to an initial position. As described above, it is possible to adjust the recording paper to a recording startup position accurately without color shaft.

Abstract: PROBLEM TO BE SOLVED: To improve the C/N of a magnetic recording medium consisting of a metal evaporated magnetic metallic thin film by specifying the temp. of a cooling can and forming a magnetic layer. SOLUTION: A nomnagnetic base 5 is supplied from a supply roll 7 and while this base is cooled along the cooling can specified in temp. to a range of -40 to 100 deg.C, the base is guided and transferred and is taken up on a take-up roll 8 in a vapor deposition device 1 for forming a magnetic tape. An evaporating source 4 is heated and dissolved by an electron beam 13 from an electron gun while the inside of an evaporating chamber 4 is evacuated to vacuum, by which the evaporating source is evaporated and the vapor thereof is deposited by evaporation on the nonmagnetic base 5. As a result, the kinetic energy of the vapor deposited particles on the nonmagnetic base 5 is suppressed and the particle sizes are reduced. The vapor deposited layer is thus formed with the good orientability of the particles.  Then, the magnetic recording medium having the vapor deposition type magnetic metallic thin film which is suppressed in noise to a lower level in spite of an increase in output and has the good C/N is produced.
