Filed: 1984-08-17
Abstract: PURPOSE:To contrive simplification of a driving circuit, by construction wherein a gear for driving the first distributing gate and a gear for driving a paper- discharging roller are operated in conjunction with a motot for driving a resist roller. CONSTITUTION:With a printing key depressed, a paper-supplying roller 53 is rotated to take out a paper P from a paper-supplying cassette 13. The paper P comes into contact with the resist roller 55, whereby the leading end of the paper P is set in order. Thereafter, when a motor 121 (not shown) is driven and the first gear 122 thereon is rotated in the direction of an arrow R, the resist roller 55 is rotated, the first distributing gate 63 is moved to the solid-line position, and the paper P is wound around a platen 50, followed by a transferring action. When transfer in all colors is completed, the gear 122 is rotated in the direction of an arrow S by the motor 121 to rotate the paper-discharging roller 65. At this time, the second distributing gate 6 is set into the broken-line position. Accordingly, since the first distributing gate 63 and the paper-discharging roller 65 are operated by the driving force of the motor 121, simplication in the driving circuit can be contrived.

Title: Branch optical cable
Inventor: ANDO YOSHIFUMI
IPC: G02B6/28
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To transmit an optical signal to many appliances with one optical cable by branching one optical cable into plural cables at the middle of it. SOLUTION: One optical cable 1 is branched into plural cables at the middle of it. In such a manner, when one optical cable is branched at the middle of it, light is scattered at the branched point, a part of it is returned in the incident direction and a transmitted light quantity is reduced, however the branch optical cable is usable in the transmission of the short distance of nearly 4 or 5 meters. For example, although an output signal from a CD player is connected to an audio amplifier with the optical cable 1, the signal is transmitted to a sound recording machine such as a cassette deck and the audio amplifier by using the optical cable branched into two cables.  In such a manner, one optical signal is simultaneously transmitted to the appliances in plural places with the same space as that of one optical cable by using the optical cable in which one optical cable is branched into plural cables.
