Title: Paper feeder
Inventor: YAMANAKA MASANORI
IPC: B65H3/52
Filed: 1981-07-08
Abstract: PURPOSE:To prevent a double feed of paper, in a paper feeder of a copying machine or the like, by forcibly contacting a friction rotary body to the uppermost paper at the point end of a paper magazine and forcibly contacting friction members to said friction rotary body in the paper feed direction at a prescribed distance. CONSTITUTION:Friction members 6, 7 are constituted with their friction coefficient smaller than the friction coefficient of a friction rotary body 5 in its peripheral surface. When paper 4 is fed by the friction rotary body 5, the paper 4 is forcibly contacted to the friction rotary body 5, by the first and second friction members 6, 7. When the paper 4 is doubly fed, the paper 4 located at the side of the friction member 6 causes a slip by a difference of the friction coefficients between the friction rotary body 5 and the friction members 6, 7, and its feed is blocked then the paper is separated. Even if the paper passes through  the friction member 6, the paper is similarly applied with separating action by  the second friction member 7 and separated. In this way, a double feed can be surely prevented.

Filed: 1988-04-28
Abstract: PURPOSE:To compensate a change in video signal level caused by a temperature change or secular change by successively changing the amplification degree of an amplifier when the original of a reference density is read and fixing the amplification degree of the amplifier at the moment when the video signal level reaches a certain voltage value. CONSTITUTION:When video signals are impressed upon the video signal input terminal 20 of an amplifier 3, a circuit 5 which actuates a group of switches successively short- circuits or opens switches 16-19 connected in series so that the resistance values of 2<4> sets of resistances 12-15 connected in series can be changed from the lowest ones to the highest ones. Then the video signal output level of a video signal output terminal 8 is successively raised by amplification and, at the moment when the output level exceeds the terminal voltage level of a reference voltage terminal, a signal is outputted from a voltage comparator 6 and the operation of the circuit 5 which actuates the switch group is stopped. Therefore, the video signal output obtained when the original of a reference density (mainly a blank original) is read always shows a value which is nearly equal to a reference voltage value. Accordingly, a change in the video signal output value caused by a temperature change or secular change can be compensated.

Abstract: PURPOSE: To prevent a lock device from being broken so as to prevent the lock device from being illegally unlocked, by providing a stationary protrusion projected outward from a casing in parallel with a locking part so that the stationary protrusion is inserted in a key hole when the locking part is inserted into the key hole. CONSTITUTION: A regular key is made to approach a casing 1, and protrusions of the key are fitted in caves so that magnet tumbler 3 is separated from a recess in order to make the casing 1 and a rotor 2 turnable, relative to each other. In this condition, the casing 1 is turned together with the regular key, that is, the casing 1 is turned, relative to the rotor 2. In this phase, a slider 5 and a locking part 6 are moved diametrically due to the rotation of a cam wall part of the casing 1, and accordingly, the locking part 6 is removed from the key hole in the lock device 30. Further, if a different kind of a key is made to approach the casing 1, the tumbler 3 is held in a recess of the casing 1 in an engaged condition, so that the casing 1 and the rotor 2 cannot be relatively rotated. Accordingly, the diametrical movement of the locking part 6 is inhibited so that the locking condition is held.
