Abstract: PURPOSE:To make it easy to remove a paper clogging between a carrying means and an overlap feed preventing means by providing a blank form feeding cassette with the overlap feed preventing means to allow the overlap feed preventing means to get out of a cassette charging part together with the blank form feeding cassette. CONSTITUTION:Frictional resistance caused by a friction member 47 is given to an overlap feed preventing roller 20 attachedly provided on a paper feeding cassette 10 at every time when the cassette 10 is drawn out of a cassette charging part 11, and the overlap feed preventing roller 20 is thereby rotated as much as a fixed angle in a direction P opposite to that of paper feeding. Thus a nipping space between a carrying roller 19 and the overlap feed preventing 20 is varied to prevent the nipping surface of the roller 20 from partially wearing. In addition, since the roller 20 can be drawn out of the cassette charging part 11 together with the blank form feeding cassette 10, the paper clogging between the carrying roller 19 and the overlap feed preventing roller 20 can be easily removed.

Inventor: OKADA TAKEHIRO
IPC: G03B5/00
Filed: 1982-11-17
Abstract: PURPOSE:To enable focusing while performing zooming by providing an operating means for zoom operation to a focusing ring. CONSTITUTION:While an operating switch 3 is in a neutral position, the 1st contact piece 10 and the 2nd contact piece 11 do not contact with a contact point 18 and a contact point 19 which are formed of a conductive material and are provided at the front ends of a switch 5 on a wide side and a switch 6 on a telephoto side and therefore a DC motor 14 does not operate. If the wide operating surface 3a of the switch 3 is pushed, the contact point 18 of the switch 5 conducts with the piece 1 and a zooming operation can be made even if the ring 4 is turned in any way. The 1st DC motor switch 20 and the 2nd DC motor switch 21 are changed over to contact points C1 and C2 sides, thus changing over the rotating direction on the motor 14 side in this stage is completed. The switches are similarly changed over to the contact point d1, d2 sides in the telephoto operation as well and therefore the motor 14 is run forward and backward in accordance with the telephoto operation and wide operation.
