Abstract: 1287130 Selective punching apparatus RICOH KK 27 Oct 1969 [4 Nov 1968] 52621/69 Heading B4B [Also in Division B6] An information recording arrangement comprises a slidably mounted holder 4 for holding a record card 3, a number of members e.g. punches 19, actuable in response to displacement of a corresponding push-button 5a, 5b, 5c, means 7, 34 for displacing the holder by a predetermined distance in response to the return of a displaced push-button to its initial position and means 36, 36a for locating the holder when it is displaced. The holder 4 is mounted on rollers 11, 12, 13, 14, Fig. 3, journalled on the housing of the apparatus and provided with a recess 4e for the card 3; a rack 7 is secured to the holder which co-operates with a pawl 34 to effect displacement of the holder. The punches 19 are pivotally connected to members (15, 16, 17), Fig. 12 (not shown), which are adapted to pivot about a shaft 18 together with the push-buttons 5a, 5b, 5c. The punches co-operate with slits (22a 1 , 22a 2 , 22a 3 , Figs. 14, 15) formed in a rubber plate (22a) secured to a member (22) over which the holder moves. The members 15, 16, 17 are formed with portions 15a, 16a, 17a which are arranged to contact a pivoted plate 28, Fig. 18A, which is shaped in such a way that when a particular punch is actuated, the remaining punches are blocked from being actuated. The punches are prevented from returning to their initial position unless they have been fully depressed by means of teeth (15c, 16c, 17c), Fig. 12 (not shown), on the members 15, 16, 17 engaging with a pivoted pawl member 30, Fig. 6. The pawl 34 for indexing the holder is pivotally mounted on a plate 33 which is pivoted on the shaft 18 and is arranged to normally contact the members 15, 16, 17, so that the pawl is held out of engagement with the rack 7 by means of a rod 39, Fig. 6. Upon depressing any of the pushbuttons, the plate 33 is pivoted so as to allow the pawl to drop into a tooth on the rack and, when the selected push-button is returned by a spring 25, the holder is indexed forward. The holder is held in the indexed position by means of a roller 36a, Fig. 6, engaging in the teeth of the rack, the roller being mounted on a pivoted lever 36 normally engaging with an extension 33c of the plate 33 so that until a push-button is actuated, the holder cannot be moved. In a modification (Fig. 10, not shown) the plate 33 is connected to a solenoid (41) via a linkage 40, 42 so that the holder can be indexed by remote control. In a further modification each of the members 15, 16, 17 is arranged to actuate a switch which in turn energizes a lamp thus indicating which button has been depressed. The punches may be replaced by printing elements.
