Title: Improved record reading mechanism
IPC: G06K13/077
Filed: 1959-12-10
Abstract: 906,666. Sensing record cards. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 10, 1959 [Dec. 10, 1958], No. 42022/59. Class 106 (1). In a record card sensing apparatus the card is fed step by step past brushes 23, Fig. 2, under the control of a stepping motor, the motor being stopped when a perforation is detected so that sensing of that perforation continues until auxiliary apparatus to which the sensed data is passed signals that the data has been registered, whereupon the motor continues the card feed until the next perforation is sensed. During sensing the cards move in guides formed by plates 16, 17 having inturned flanges 18 underneath to embrace the edges of the card. The cards are inserted in the guide plate 16 by hand but are gripped between the feed rollers 28 and counter rollers 30 as they pass the brushes. Two card levers 36 and 37 are provided which operate in succession as the leading edge of the card traverses the sensing line. The stepping motor 45, Fig. 3, is energized through relay contacts A-4 and ST-2. A rectifier 51 supplied by transformer 50 provides D.C. voltage to a contact bar 22 extending between the feed rollers for engagement by any brush 23 that finds a card perforation. Card lever contacts 38, 40 close as the card enters the sensing position to connect the zero voltage output of the rectifier via relay ST, resistance 53 and terminal 14 to the start control of the auxiliary apparatus, e.g. a card punch. When relay ST is energized contacts ST-2 close and the stepping motor feeds the card until a perforation is sensed. A connection 54 common through diodes to all the brushes then receives a potential which is passed through contact G1 and resistors 55, 56 to a tube 57 which conducts and energizes relay A. Contact A-4 opens to stop the motor stepping and contact A-1 closes to operate relay G opening contact G1 to prevent a second conduction of the tube 57. Contact A-2 short-circuits the tube 57. When the data has been punched in the auxiliary machine, the relay ST is deenergized thereby opening contacts ST-1 deenergizing relay A and allowing contacts A-4 to re-close. Relay ST then operates again and feeding re-commences. The card is thereby fed column-by-column through the sensing position stopping wherever perforations are sensed in a column to allow the auxiliary machine to operate. The machine feeds past all blank columns without this pause. Specifications 684,273 and 842,364 are referred to.

Abstract: 1450584 Reflex cameras ASAHI KOGAKU KOGYO KK 20 Sept 1973 [21 Sept 1972] 44180/73 Heading G2A A reflex camera mechanism includes a cam which when operated in one mode adjusts the diaphragm to a pre-selected aperture setting, and when operated in another mode adjusts the diaphragm to that setting and also raises the mirror. The Fig. shows the mechanism in the rest position. To adjust the diaphragm to a pre-selected aperture setting the cam 5 is rotated by handle 6 in direction A. This causes link arm 9 to rotate anti-clockwise, hence also pivoting anti-clockwise a member 7 mounted on the mirror casing, which adjusts the diaphragm to the pre-selected value. During this movement another link arm 10 in contact with the cam does not rotate, because it travels over a part of the cam profile which is equidistant from the cam-shaft 11. The cam is returned to the position shown, and then rotated in direction B. Link arm 9, and hence member 7, is again rotated anticlockwise, so that the diaphragm is adjusted to its pre-selected setting. This time link arm 10 is also pivoted anti-clockwise, and engages with a pin 4 on a lever 3 to pivot it clockwise. During this movement lever 3 engages with a pin 2 on the mirror 1, so that the mirror is pivoted into its raised position.

Abstract: 1,161,433. Typewriters. GRAPHIC TECHNOLOGY Ltd. 5 Oct., 1967 [7 Oct., 1966], No. 44805/66. Heading B6F. Feeding page-width transfer material.-In a typewriter or line machine in which continuous stationery is fed past a printing station and where such movement tends to draw off carbon papers from supply spools, the carbon papers are fed at a slower rate than the stationery by an independent motor which is energized only during actual movement of the stationery. The carbon paper supply spools are mounted on spindles 18 and have fixed thereon, helical spur gears 20 which mesh with gears 19 on a common shaft 21 driven by a gear 30 from the independent motor 33. The common shaft is biased so the gears 19, 20 are not in engagement so that manual manipulation of the carbon webs is possible. A knob 25 permits the gears 19 to be axially shifted into engagement and latched thereby a lever 27 engaging a slot in the spindle 21. Such axial movement causes a collar 34 to engage a lever 36, close a switch 38 and light a lamp 40 which indicates that power is connected to the feed device and to the typewriter. A further collar 35 operating a lever 37 and a switch 39 moves an additional distance to the left, Fig. 2, only when there is actual feeding movement of the stationery. This closes the switch, lights a second lamp 41 and starts the independent motor. The additional movement is derived from the axial thrust of the helical gears 19 due to the rotational pull on the spindles 18 caused by the feeding of the stationery. When the stationery feed stops, the drive of the motor 33 causes a reverse axial thrust and the switch 39 is opened and the motor 33 stops.
