, The presenl in~en~ion rclatcs to a data registcr wi~ll a registcr card selection mecilanism comprising a housing ~hich has a covcr and a base with a plurality of selector keys which are juxtaposed and superimposed in rows and a drawer which is under the action of a compression spring and which is closable by means of a locking mechanism, whereby a large number of register cards arestacked in said drawer with selection tongues having open-ings formed in the rear edge portions thereof, said tongues increasing in size in step-like manner by in each case one opening-containing selection tongue from one side to the other of the register card with~the first open-ing to the opposite register card, whereby each selection key is fixed to aswivel arm co~structed as a lever which at its free end carries a card re-straining pin, whereby the card restraining pins of the swivel levers are arranged in a row and cooperate with the register cards in such a way that on depressing a selector key, all register cards located above the register card associated with this selector key are held back on extending the drawer by inserting the card restraining pins into the openings of the selection tongues of the register cards, whilst the selected register card and all the cards located below it are moved out with the drawer, as well as a device operable by the swivel levers of the selector keys for unlocking the dTawer snd releasing the register cards selected by a selector key by forcing out the unlocked drawer by means of the compression spring and provided with cams for engaging with cam perforations on the register card.
Various constructions of data registers with selection mechanisms are known. They comprise a housing for receiving a stack of loose register cards and a keyboard with correspondingly marked finger keys whose operation selects thc desired cards. The register cards can contain random information for subsequent reference in alphabetical order. A known construction of a data register is made relatively flat in the closed state and is opened by means of a plurality of keys which are manually opcrated in order to open the desired register at the desired point, ~hereby making freely visible the ~.151701 Iformation on the c~rds. Thc thus constructc-l data register is also pro-vidcd with a closing key by mc~ns of ~hich the cover which covers the regis-ter card can be transferred into the closed position, thereby simultaneously with the closing of the cover, the raised register cards are automatically returned to their initial position.
In addition~ a data register is known which comprises a housing with a drawer for receiving the register cards which is closed by a bolt and is under the action of a thrust spring and a device for unlocking the drawer and releasing the register card selected by means of a set key by forcing out the unlocked drawer by means of the thrust spring.
These known data registers are constructed as standing devices and are placed on a support. The data register housing can also be provided with a surface which serves as a support for a telephone if the said housing is equipped with a drawer which moves the selected register card out of the housing.
However, it is common to all these data registers that the key-board comprising a plurality of selector keys is arranged in the front area o~ the register, whereby the selector keys are juxtaposed in rows. In addi-tion, the known data registers having relatively large dimensions are known.
In addition, a device for selecting one of the plurality of cards stored in a housing is known, said cards being selected by key pressure and horizontally stacked in a drawer arranged in an opening in the front wall of the housing and moved horizontally into the housing in a closed position and horizontally out of the housing in an open position in which it can be locked relative to an initial stress, to which end a latch with a shackla is pro-vided which is movably secured in the housing and under an initial stress and engages in a notch in the drawer. In addition, a key lever is provided for each card which has a rod fixed in pivotable manncr in the housing on whosc one end is provided a manually opcrable key locatcd outsidc the housing, whilst at the other end of tho key lever is provided on onc side a shoulder or unlatching ti~e shac~l~ on operating the key and on the other side a shoulder which cooperates with thc cards having aligned reccsses in such a way that on depressing the key all the cards above the card associated with said key are prevented from moving with the drawer, whilst the selected card and all the cards located below it are moved out with the drawer.
In ~he case of this known selection mechanism, a plurality of card - cams corresponding to the number of cards is hinged to the drawer and by means of attachments arranged at the end of the key lever opposite to the key, said cams can be moved into an engagement position at the rear edge of the selected card and the cards located below it on depressing the corre-sponding keys, whilst the attachment cooperating with the cards is construct-ed in such a way that it simultaneously engages in a recess of all the cards located abové the selected card in order to prevent them from moving.
This known selection mechanism has a very complicated construction in view of the fact that a plurality of card cams corresponding to the number of cards is hinged to the drawer, which can be brought into the operating position by attachments on the key levers, whilst the attachment cooperating with the cards is constructed in such a way that it sumultaneously engages in a recess o all the cards located above the selected cards in order to prevent any displacement thereof.
The problem of the present invention is to provide a data register which has very small dimensions, which is operationally reliable and permits a completely satisfactory separation of the selected register cards without significant technical expenditure, accompanied by a minimum areal arrange-ment of the selector keys.
According to the invention, this problem is solved by a data regis-ter o the type described herinbefore:
a) wherein the selector keys of thc swivel levers comprisc plate-like, square or rectangular blanks fixed to the ends thereof, with selector keys arranged one behind the other iJt any one row having a width which corresponds ` ; liS170~ ~

`D the width of the l~rticular swivcl lever wllich carries thrcc selcctor keys and are connectcd thercwith in such a way that the selector key facing the card restraininO pins at thc rcar ends of the swivel lever projects over the two adjacent swivel levers to the right and the front selcctor key pro-- jects over the two adjacent swivel levers to the left and the central seIec-. tor key projects to the right and left over the swivel lever adjacent to said key on either side, b) wherein the card restraining pin of each swivel lever:comprises an ap-proximately U-shaped portion shaped onto the end of the swivel lever with a leg leading to the selector keys onto whose end is shaped a vertically up-wardly directed rod which on operating a swivel lever engages from below into the register card opening or recesses, wherein c) the drawer comprising a plate-shaped drawer bottom with a front terminal strip which seals the drawer extension opening in the housing front wall when the drawer is inserted is made open at the back and on either side and in its rear edge area has a plurality bf slot-shaped recesses corresponding ; to the number of card restraining pins and having a lengt4 corresponding to the length of the U-shaped portion on the ends of the swivel levers, whilst the two lateral drawer limiting walls are formed by two boundary walls shaped onto the inner wall surface of the housing cover and arranged on either side of the plate-shaped drawer bottom, d~ wherein for guiding the swivel lever each swivel lever is provided on the end carrying the card restraining pin with a vertical slot-shaped open-ing into which engages a cam shaped onto the inner wall surface of the hous-. ing cover and is guided in the opening, o) wherein themechanism for unlocking the drawer comprises a U-shaped shackle articulated to the cover of the housing and whose web which is at right angles to the longitudinal direction of the swivcl lever rosts on the top of the swivel arms and is subject to the action thereof, whilst each shackle member has a locking cam on its bottom face facing tlle drawer which llS~

cooperates with a counter-cam shaped onto the drawer in such a way that on raising the shackle on operating a selector key the locking cam is disengaged from the counter cam so that the draweris extended outwards.
In accordance with the present invention, there is provided a card engaging device comprising a first leg, said first leg being attached to means for providing movement to said card engaging device, a second leg extending away from said first leg and a third leg ex-tending away from said second leg in a direction substantially parallel to said first leg, a card restraining pin extending from said third leg toward said first leg.
In accordance with another aspect of the invention, there is provided a data register with a register card selection mechanism comprising a housing which has a cover and a base with a plurality of selector keys which are juxtaposed and superimposed in rows and a drawer which is under the action of a compression spring and which is closable by means o a locking mechanism, whereby a large number of register cards are stacked in said drawer with selection tongues having openings formed in the rear edge portions thereof, said tongues increasing in size in step-like manner by, in each case, one opening-containing selection tongue from one side to the other side of the register card with the first opening disposed opposite the first opening of the preceding register card, whereby each selector key is fixed to one end of a swivel lever which at its free end carries a card restraining pin comprising an approximately U-shaped portion shaped onto the end of the swivel lever with a leg leading to the selector keys onto whose end is shaped a vertical-ly upwardly directed rod which on operating a swivel lever engages ~S170~

from below into the register card openings or recesses, whereby the card restraining pins of the swivel levers are arranged in rows and cooperate with the regis~er cards in such a way that, on depressing a selector key, all register cards located above the register card associated with this selector key are held back on extending the drawer by inserting the rods into the openings of the selection tongues of the register cards, while the selected register card, and all the cards located below it are moved out with the drawer, as well as a mechanism operable by the swivel levers of the selector keys for unlocking the drawer, said mechanism consisting of a shackle articulated to the housing and whose web, which extends at right angles to the longitudinal direction of the swivel levers, rests on top of the swivel lever and is subject to the action there-of, and which co-operates with the cam shaped on to the drawer in such a way that on raising the shackle on operating a selector key the locking portion of the shackle di.sengages from the cam so that the drawer is extended under spring tension, said drawer being provided with cams for engaging with cam perforations on the register cards, characterized in that each card restraining pin comprises a first leg attached to said swivel level; a second leg extending away from said first leg and a third leg extending away from said second leg in a direction substantially parallel to said first leg, a card restraining pin extending from said third leg toward said first leg.
By means of the data register constructed according to the invention, a register card selection mechanism is provided which, due to the fewer components, namely housing, drawer, swivel levers with shaped selector keys and shaped card restraining pins and - 5a -~iS~70~ ~

drawer unlocking mechanism by means of a swivel shackle operated directly by the swivel arms on the operation thereof which can be manufactured in a very economic manner. Due to the small number of components, assembly is easy and can also be performed by un-trained staff. The small number of structural parts is particularly advantageous when carrying out any repairs which may be necessary.
~ue to the special construction and arrangement of the selector keys relative to their swivel levers, the levers can be housed in a very small area within the housing because they are arranged very close together. The arrangement of the card restraining pins at the ends of the swivel levers in a recess formed in the base plate of the bottom of the housing permits a shallow construction of the data register. Even when the selector keys are operated incorrect-ly, incorrect select;on is not possible because the ends of the swivel levers carrying the card restraining pins are individually guided on cams, so that a tilting or displacement of the end areas of the swivel levers is not possible. No additional devices are necessary for supporting the swivel arms in their initial position with spring-operated devices. The swivel lever ends with the card restraining pins supported on the base plate on the bottom of the housing. The completely reliable operation of the data register is also ensured through the swivel arms for controlling the un-locking mechanism for the drawer being directly operable by the swivel arms on actuating the same without additional mechanical devices having to be provided. As the swivelling of each swivel arm is directly transferred to the swivel shackle, there is also a direct actuation of the drawer unlocking mechanism, - 5b -~51~0~

so that at the time when the card restraining pin engages in the openings of the register cards remaining in the housing, the drawer is unlocked and is moved out of the housing with the selective card and the stack of cards located below the sam~e.
The data register housing is also economic to m~nufacture because a box type drawer is no longer ne oessary. m e drawer merely consists of a plate-like blank without side walls and without a rear wall. me side walls are formed by the limiting walls shaped onto the inner surface of the housing cover.
Furthermore, the data register housing has very small dimensions which is also achieved through providing slot-shaped re oesses in the rear end area of the drawer which correspond to the bent portions carrying the card restraining pin at the ends of the swivel levers, so that in the drawer inser-tian, said bent portions rest in the slot-shaped reoe sses. m us, the drawer can have large dimensions, so that the entire bearing surface of the drawer ,1 is available for the stack of register cards, so that large cards can be used.

The data register shown in Figures 1 to 5 comprises a housing 10 with a box-shaped cover 11 and a box-shaped base 21. Cover 11 and base 21 ; are interconnected by means of screw or adhesive connections and are pref-erably made from plastic. The cover 11 with side walls 13 and 15, front wall 12 and rear wall 14 has an upper cover plate 16 in which an approximate-ly square or rectangular opening 17 is formed in the vicinity of front wall 12. The portion of upper cover plate 16 carrying opening 17 slopes in a slightly desk-shaped manner. The remaining area o cover plate 16 can be provided with a non-slip layer and have a side which serves as a bearing surface for a telephone or the like.

~.~.S1701 ` Basc ~1 witll sido walls 23 and 25, ~ront wall 22 and rear wall 24 has a base platc 26 ~nd a slot-shapc(~ opening 27 in front wall 22 which serves to receive a drawer 30.
The base 21 of housing lO receives the drawer 30 which comprises a plate-shaped drawer base 31 and a front terminal strip 32 which, when drawer 30 is inserted, seals the drawer removal opening 20 in the front wall 22 of base 21. Drawer base 31 has a cam 33 in its centre and on its top tFigures 8 and 9). The side walls of drawer 30 are formed by two limiting walls 19 and l9a which are shaped onto the inside of housing cover 11 (Fig-ures 10 and 11).
For the purpose of extending drawer 30, a steel spring rod, not shown in the drawing, is arranged on base plate 26 of base 21 in such a way that its one free end is connected to the plate-shaped drawer base 31, whilst the other end thereof is rigidly connected with basé plate 26 of base 21. The action of the steel spring corresponds to that of a thrust spring which i5 placed under tension on inserting drawer 30 into base 21 of housing 10 so that on unlocking drawer 30 the drawer is extended by means of the steel spring rod which springs back into its initial position.
A plurality of square or rectangula~r selector keys is arranged in the area of tpening 17 in upper cover plate 16 of cover 11 of housing 10, the arrangement being such that the total area formed by the selector keys fills the opening 17 in cover 11.
In the embodiment shown in Figures 1 and 2, twelve selector keys 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50 and 51 are provided which are correspondingly marked and in fact with the letters of the alphabet in such a way that selector key 40 carries letters "A,B" key 41 letters "I,J,K", key 42 letters "S,T", key 43 letters "C,D", key 44 letters "L,M", key 45 letters "Sch", key 46 letters "E~", key 471etters "N,0", key 48 letters "U,V", key 49 lotters "G,ll", key 50 lettcrs "P,Q,R", and key 51 lettcrs - 30 "W,Z". The twelve selector keys 40 to 51 are juxtaposed in thrce rows and :
:. .
, . . .
, - 8 -', : , :

`' ~ 1151~01 ~rranged one bellind thc other in four rows, so that ~cys 40, 41, 42 and 43, 44, 45 and keys 46, 47, 48 and 49, 50, 51 in each case form one row.
Keys 40 to 51 arc connccted to a num~er of lever~ e swivel arms 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70 and 71 corresponding to the num-ber of keys and on whose ends 60a, 61a, 62a, 63a, 64a, 65a, 66a, 67a, 68a, 69a, 70a and 71a are fixed selector keys 40 to 51, whilst the other ends of swivel lever 60 to 71 are designated by 60b, 61b, 62b, 63b, 64b, 65b, 66b, 67b, 68b, 69b, 70b and 71b (Figure 7). Swivel levers 60 to 71 are construct-ed as two-armed levers and are mounted in swivellable manner by means of a swivel axis of the side walls 13 and 15 of cover 11 in such a way that swivel levers 60 to 71 are provided centrally with openings which are at right angles to the longitudinal axis of the swivel levers and through which is passed swivel axis 80 in such a way that swivel levers 60 to 71 are arranged so as to swivel freely on swivel axis 80.
In the area of its ends 60b to 71b, each swivel lever 60 to 71 has a vertical slot-shaped opening 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100 and 101 in which engage guide cams 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120 and 121 shaped onto the inner wall surface of the upper cover ; plate 16 of cover 11 (Figure 10). The length of guide cams 110 to 121 is dimensioned in such a way that the free ends 60b to 71b of swivel lever 60 to 71 with their slot-shaped 90 to 101 are guided by means of said cams 110 to 121 so that a lateral displacement of the swivel lever ends 60b to 71b is prevented. The arrangement offers the further advantage that it is no longer necessary to fix the swivel levers 60 to 71 on pivot axis 80 to prevent any displacment.
The selector keys 40 to 51, which comprise plate-shaped square or rectangular blanks and which are advantageously fixed by means of vertical webs to the ends 60a to 71a of swivel levers 60 to 71 have a width which is such that the width formed by the sum of the selector keys 40, 43, 46, 49 and 41, 44, 47, 50 and 42, 45, 48, 51, which are juxtaposed in rows, is no l~Sl~J~ ~

r~`~ider than tlle total l~idtll formed by the swivcl levers 60 to 71. The arrangement of thc selector kcys ~0 to 51 on swivel levers 60 to 71 is explained relative to Fi~ures 15 to 19 by using the exam~le of selector keys 40, 41 and 42. Selector keys 40 to 42 are arranged one behind the other in a row and fixed to the ends 60a, 61a and 62a of swivel levers 60, 61 and 62. Selector 1ey 40 is fi~ed to the end 60a of swivel lever 60 in such a way that the plate-shaped blank of key 40 projects to the right over the adjacent swivel levers 60, 61, 62, whereby the width of key 40 corre-sponds to the width of the three swivel Ievers 60, 61, 62. Selector keys 41, 42 also have widths which in each case correspond to the width of the three swivel levers 60, 61, 62. The central selector key 41 is fixed to the swivel lever end 61a in such a way that the plate-shaped selector key blank projects to both sides and the adjacent swivel levers 60 and 62 are overlapped by it. The front selector key 42 is fixed to swivel lever end 62a in such a way that its plate-shaped blank projects to the left and pro-jects over the two swivel levers 60, 61 ~Figures 17, 18 and 19). Selector keys 43, 44, 45 and 46, 47, 48 and 49, 50, 51 are fixed to their swivel levers 63 to 71 ln the same way as selector keys 40, 41, 42.
The end 60b to 71b of each swivel lever 60 to 71 carries a card restraining pin 130 tFigure 6). Each of these card restraining pins 130 is formed by a U-sl-aped portion 140 with webs 140a and leg 140b which is par-allel to the swivel lever end. The other leg of the U-shaped portion 140 is formed by the end portion 60b or 61b to 71b of the individual swivel levers 60 to 71.
The free end of leg 140b of U-shaped portion 140 of card restrain-ing pin 130 carries a vertical rod 130a which constitutes the actual card restraining pin. The arrangement and construction of the card restraining pins 130 on swivel lever ends 60b to 71b are such that on operating one swivel lever by depressing the corresponding selector key the rear end of the swivel lcvcr is raised, whcrcby simultaneously rod 130a of U-shaped por-, - 10 -.

,; ~

l~Si~
~ion 140 of thc relcvant swivcl lcvcr is r~ised and as will be explLIined in greater detail hereinafter cngagcs in thc openings or reccsses on the rear edges of the register cards of the stack of register cards located in drawer 30, as intimated at 200 in Figure 6.
In order that the data register has a limited height, a recess 27 (Figure 6) is provided in base plate 26 of base 21 in the area of the bearing surface of U-shaped portions 140 of card restraining pins 130. The depth of recess 21 approximately corresponds to the height of webs 140b of the U-shaped portions 140 of card restraining pins 130, w'nereby however the depth of recess 27 can also be larger. Recess 27 must be constructed in such a way and the association of swivel axis 80 for swivel levers 60 to 71 must be such that the swivel levers are slightly inclined in the inoperative position as shown in Figure 6. In this inoperative position, the webs 140b of U-shaped portions 140 of card restraining pins 130 are supported on the base surface of recess 27. This construction ensures a perfect engagement of rod 130a of card restraining pins 130 in the openings in the rear edge areas of the cards of the stack 200 of register cards. In addition, the individual rods 130a can be provided with a rear bent portion 130b, but its surface area must be no larger than the openings provided in the edge areas of the register cards. This rear bent portion 130b of rods 130 prevent, on extending drawer 30, any lifting of those cards ~hich are located below the selected card and are moved out with drawer 30. This construction of rod 130 i5 particularly advantageous in the case of register cards which follow-ing prolonged use are no longer flat.
In order to be able to extend drawer 30 after operating a selec-tor key, an unlocking mechanism is provided which is actuated by means of a swivel shackel 150 (Figures 12, 13 and 14). This swivel shackle 150 is a U-shaped shackle with legs 151 and 152 and a rod 153 which interlinks said legs. At the ends 151a and 152a of legs 151 and 152, the swivel shackle 150 is articulatcd to the outer wall surfaccs of the vertical limiting walls . - 11 -~151701 r `9 and l9a, which arc shapcd onto the covcr 11 (Figure 10). Ilowever, the possibility e~ists of articulating swivel shac~le 150 with its leg ends 151a and 152a to the inner wall surfaces of side walls 23 and 25 of base 21. The swivel shackle 150 is fixed in such a way that it can be swivelled about the swivel axis indicated at 155 in Figure lO. In addition, swivel shackle 150 is arranged in such a way that when the data register is not in use, web 153 of shackle 150 rests on swivel levers 60 to 71 namely in the area of their ends 61b to 71b. However, the possibility also exists of extending the leg 140b of U-shaped portion 140 of card restraining pins 130 over and beyond the vertical web 140b (Figure 6). The complete extended portions 140c then serve as a bearing surface for web 153 of U-shaped swivel shackle 150 lead-ing to the advantage that the housing 10 of the data register has only a limited height. On operating a selector key, only a limited lift is then required for raising the swivel shackle 150.
As shown in Figure 14, the drawer unlocking mechanism comprises a locking cam 1~6 shaped onto the bottom of each leg 151 and 152 of swivel shackle 150. Locking cam 156 comprises an approximately triangular body with an approximately vertical stop face 156a facing the rear ~11 of hous-ing 10. Counter-camslS7 shaped onto the drawer bottom 31 on either side thereof engage with stop face 156a. Each of the counter-cams 157 is con-structed as a triangular body with a vertical edge 157a facing the front of housing 10.

According to Figure 14, the operation of the drawer unlocking mechanism is such that on operating a selector key in the direction of arrow X, the free end of the swivel lever carrying the card restraining pin 130 is ~wivelled upwards in the direction of arrow ~ and simultaneously swivel shackle 150 is swivelled upwards in the direction of arrow Y. During the swivelling of swivel shackle 150 in the direction of arrow Y, the two lock-~ ing cams 156 on legs 151 and 152 of swivel shackle 150 are disengaged from : 30 thc counter cams 157 of drawer 30 so that under spring tension drawer 30 . - .

. , .

-:, 115~701 `~an be extended in the dircction of arrow Yl. If after cxamining a register card, drawer 30 has once ;Igain to assume a position within housing 10, it is inserted counter~to the tcnsion of the spring until the counter-cams 157 and drawer 30 engage behind the locking cams 156 on swivel shackle 150, whereby the latter assumes its inoperative position. By inserting drawer 30 into - housing 10, counter-cams 157 are assisted in sliding past the locking cams 156 by the wedge-shaped guide surfaces 156b and 157b of cams 156 and counter-cams 157. When on inserting drawer 30, its counter-cams 157 have assumed their position behind the locking cams 156 of swivel shackle 150, the,latter moves into its lowermost position due to its own weight or aided by a spring and thus locks drawer 30.
In order that in the inserted position, drawer 30 offers a maximum bearing surface fGr the stack 200 of reglster cards, the plate-shaped drawer base 31 has a number of slot-shaped recesses 160 to 171 corresponding to the number of card restraining pins 130. The length of each slot-shaped rocess 160 to 171 corresponds to the length of leg 140b of U-shaped portion 140 o~ each card restraining pin 130, so that in the inoperative position of swivel levér 60 to 71 the U-shaped portions 140 with their legs 140b extend-ing in the direction of the front of housing 10 come to rest in the slot-shapet recesses 160 to 171. Due to this construction, swivel le~ers 60 to 71 are aligned in the inner area of housing 10, so that on actuating a selec-tor key thé corresponding card restraining pin can engage without any lateral displacement in the openings on the rear edge areas of the register cards.
The stack 200 of register cards arranged In housing 10 has a num-ber of register cards 201 to 212 corresponding to the number of selector ke,ys 40 to 51, whereby card 201 is the uppermost card and card 212 is the lowermost card in stack 200 ~Figures 20, 21, 21a).
Each card 201 to 212 is provided with a marginal recess and with a plurality of slot-shaped openings, whereby the marginal reccss extends from the uppermost card 201 to the lowermost card 212 from the left-hand to the ,.... .

liSi701 Therefore, the selection of a rcgistcr card takes place in such a way that on oper~ting a selcctor ~cy by means of the swivellable swivel lever, the card restraining pin ~itll its rod 130 engages from below into the recesses and the superimposed opcnings, so that, extending the drawer, all the register cards are held back which.are located above the selected card, this being effected by the rod 130a which is passed through the open-ing, whilst the other card positioned below it can be moved out with the drawerJ because rod 130 is passed through the recesses below the openings of the superimposed cards and is therefore unable to hold bàck these cards.
Register cards 201 to 212 are made ~rom cardboard, pasteboard or the like and can be pro~ided with corresponding line guides, fields and the like. In addition, each register card 201 to 212 carries those letters corresponding to the letters of the alphabet which appear on the selector ~ey associated with the corresponding card. Thus, card 201 is provided with letters "A,B", card 202 with letters "S,T", card 203 with letters "I,J,K", cart 204 with letters "C,D", card 205 with letters "Sch", card 206 with letters "L,M", card 207 with letters "E,P", card 208 with letters "U,V", card 209 with letters "N,0", card 210 with letters "G,H", card 211 with letters "W,Z", and card 212 with letters "P,Q,R".
As shown in Pigure 20, all the register cards 201 to 202 have a slot-shaped opening 240 in the centre thereof in which engages the cam 33 on the plate-shaped draw bottom 31. Cam 33 is also triangular, so that the cards to be moved out with the drawer are seized by cam 33 and can be car-ried along, whilst the cards held back by card restraining pins 130 cannot be carried along by cam 33.
