摘要:
When an operator manually rotates flanges for holding roll paper, flange placement rollers rotate accordingly. Paper is supplied from the roll paper, and rotational force of one of the flange placement rollers is transmitted to a drive roller by a gear mechanism. Once the tip portion of the paper is held between the drive roller and an idler roller, the paper is semi-automatically fed to a set position by rotation of the drive roller. A torque limiter is provided in the gear mechanism to prevent an undesirably large load from being exerted on the paper.

When an electromagnetic clutch 45 is turned on, a rotating force of a main motor 62 is transmitted to a shaft 42 of a drive roller 41a of transport rollers 41 through a double gear 49 and a high-speed gear 46. As a result, the drive roller 41a rotates so as to produce a transport speed higher than the circumferential speed of a photoreceptor drum 13, thereby looping a transfer material P. When the electromagnetic clutch 45 turned off, the rotating force of the main motor 62 is transmitted to the shaft 42 through the double gear 49 and a low-speed gear 47. Accordingly, the drive roller 41a rotates so as to produce a transport speed lower than the circumferential speed of the photoreceptor drum 13. As a result, the loop of the transfer material P gradually shrinks and finally disappears. The drive roller 41a is therefore separated from the main motor 62 by the action of a one-way clutch 48, to follow the rotation of the photoreceptor drum 13 while exerting tension on the transfer material P.

A nitrogen-containing perfluoroalkanoyl peroxide is provided which is represented by the formula: ##STR1## wherein Rf.sub.1 and Rf.sub.2 independently stand for an alkyl group of 1 to 5 carbon atoms, provided that Rf.sub.1 and Rf.sub.2 are joined to each other in one of the three patterns of union, 1) direct union, 2) union through the medium of an oxygen atom or 3) union through the medium of a nitrogen atom to form one of the three rings, i.e. five-membered ring, six-membered ring or seven-membered ring. The nitrogen-containing perfluoroalkanoyl peroxide is produced by a method which comprises oxidizing a compound represented by the following formula: ##STR2##

摘要:
A system for collecting information from information sources and distributing the collected information to destinations, where such information is required, writes the information collected from the sources into respective addresses of a storage by use of respective write-in devices each of which is connected directly to the respective source through a transmission route. The system reads any required information out of the storage through retrieval by use of respective read-out devices each of which is connected directly to the respective destination through a transmission route in order to distribute the read-out information to the destination. The write-in and read-out devices are connected to the storage one after another repeatedly, at a time decided by a timing device.

摘要:
A medium conveying device includes an alignment member, a skew conveying member, and a removal member. The alignment member faces one end of a medium and aligns the medium while contacting with the medium when the medium is conveyed in a first direction. The skew conveying member conveys the medium in a second direction crossing to the first direction so that the one end comes in contact with the alignment member and that includes a drive member and a driven member opposed to the drive member and driven by the drive member. The removal member has a tip end coming in contact with a face of the drive member to remove a deposit on the face. The removal member is placed along a rotation direction of the drive member so that the tip end faces downstream of the rotational direction.
