In a known cash register, one is different from two trained key adjustable safety lock for control and release the paces "intermediate" and "final total" provided, the two coaxially arranged, the range of rotation of the key-determining lock nuts, each of the introduced key via a linkage in addition to a key lock slide acts to lock the amount keys.

According to the main patent are differently designed, a single one Key lock associated key key provided for the purpose of controlling a Large number of different machine aisles with a stepped, the automatic adder selection or gait control means adjusting the sensing element cooperate in such a way that this, in accordance with the key key introduced in each case, carries out a single selection and control process and the derailleur clutch at different times of the machine operation from the machine drive turns off.

With the selection and control device mentioned, only one limited number of identical control and release processes are triggered, since the usable keypad is only available on one and the same downstream control element can act.

The steadily increasing demands on performance registering machines, however, require different types of control to be controlled Registration operations a variety of manual control means, in addition to the required Space requirements on the setting field of the machine also affect its clarity and thus complicate the operation. Since these machines usually, for example in hotels, banks or public institutions, by several machine operators are used, extensive safety devices are also required, An absolutely flawless operation of the machines and easy control to ensure over all registered business transactions.

The invention aims to improve the performance of recording machines without increasing the number of the control means arranged in the control keypad to expand and to create a versatile selection and control device, with a minimal amount of locking means by several machine operators in different Way can be used.

The object on which the invention is based is to provide the control and release function of a key lock that can be operated by different key keys for registering machines of several, independently of one another and together adjustable lock nuts dependent on one and the same key lock in or without connection with other manual control means, optionally different to effect certain release and control processes.

According to the invention of a selection and control device for Cash registers, calculators, accounting machines and the like assumed that one on machine aisle release means has acting key lock, the differently designed key keys are assigned, which with an automatic arithmetic unit selection and Gait control means cooperate connected control member, and thereby is characterized by the fact that several independently operated lock sockets in the key lock are provided for the purpose of performing different control and release processes connected to various types of control and release means and depending on the type of used key wrench individually or jointly transferable into their operative positions are.

The selection and control device according to the invention enables in the control keypad of the machine operated by several machine operators despite the large number of different control processes to be carried out and the resulting conditional significant number of keys a common key lock for to provide all key keys to be used, by means of which different Registration and billing processes with one-key and multi-key operation only from here authorized persons.

According to a further feature of the invention, the key lock are different usable key keys assigned in their various setting positions work together with one and the same lock socket to resolve different tax or To effect release processes with or without additional manual control means.

This will determine the number of keypad keys that will be used considerably reduced, since several selection keys can be made with one and the same key or control processes can be effected.

Finally, another feature of the invention is that with one and the same key lock either in addition to the adding mechanism or gait selection processes also locking means of certain control buttons or control button groups of the same or can be influenced by another control key bank.

Further features of the invention emerge from the description and the claims.

The invention is illustrated in more detail using several exemplary embodiments and described below, namely FIG. 1 shows a cash register in perspective, FIG. 2 is a side view of a gait keyboard bank, FIG. 3 shows a key blocking device in a perspective illustration, FIG. 4 shows a key lock in cross section, FIG. 5 is a top view of a key lock, FIG. 6 to 9 several details, F i g. 10 shows a setting field in a perspective illustration, FIG. 11 a side view of another key lock, FIG. 12 a row of amount keys with locking slide, FIG. 13 the row of control buttons with locking slide, FIG. 14 a key lock in a side view, FIG. 15 a key lock in a top view, FIG. 16 a key lock with a release slide and locking device, FIG. 17 shows a row of adder selection keys with interlocking means, FIG. 18 shows a key key in the view, FIG. 19 shows a key key in plan view. In addition to the setting field 1 (FIG. 1) of the cash register 2, a receipt feed device 3, for example for bills, a viewing window 4 for the control strip and an ejection opening 5 for receipts are provided. On the setting field 1, among other things, amount keys 6,7 for mark and penny amounts, a control key 8 for controlling different machine gears, a key lock 9 with a key 10 and the adder selection keys 11 to 14 are housed. A display device 15 forms the upper reduction of the cash register 2. The control key 8 and the key lock 9 are assigned to the gang bench 16 (FIG. 2), in the side wall 17 of which is a switching mechanism 18 and one in pin-and-slot connections 19, 20 and each through one Tension spring 21 influenced locking slide 22 and a release slide 23 store. A sensing element 24 of the switching mechanism 18 assigned to the gait bank 16 is connected by means of a handlebar 25 with a control slide 26 which, through the intermediary of the switching mechanism 18, effects the setting of the known automatic adding mechanism and gait selection control means.

The setting of the control slide 26 is dependent on the control key 8 or on key keys yet to be described, or on the control members 27, 28 which can be preset in a known manner by the arithmetic unit or the amount keys 6, j, which is not shown. The control members 27, 28 and derr. Shaft 29 of the control key 8 are assigned the stops 30, 31, 32 ... of the control slide 26, which also has several stepped and offset stops 33, 34, 35 ... to be influenced.

The aforementioned key slide 23 is designed as a release slide of known design and is in operative connection with a locking device 49 in a manner to be described below. The locking slide 22, which can be influenced by the key pins 37 and 38 of the control key 8 or the key lock 9 (FIG. 2, 4, 5), works with the switching pin 41 of the through the intermediary of its pins 39, 40 (FIG. 3) Release shaft 42 together in a known manner.

The key lock 9 (F i g. 4 and 5) consists of two lock sockets 43, 44, the T-shaped, irregularly formed and mutually merging recesses 45 and 46 for the introduction of the differently shaped key keys 10 (F i g. 6) for the Lock socket 44 or 47 (FIG. 7) and for the lock socket 43 have. The recesses 45 and 46 and the matching key keys 10 and 47 are optionally, as shown in FIG. 5 can be seen, profiled in such a way that the key keys which can be inserted into one lock nut are not suitable for the other lock nut.

On the lock nut 43, the aforementioned pin 38 is attached, the cooperates with the release slide 23 and the locking slide 22. aside from that are guide pins 50 (F i g. 4) mounted in bores 51 of the lock nut 43, the are influenced by the profile 52 of the key shafts 36 of the key keys 10. Counter pins 53 act on the pins 50, which are under the influx of compression springs 54 stand and are guided in bores 55 of the lock housing 56. The holes 55 are closed off by a cover plate 57 which is screwed onto the lock housing 56 is. On the lock nut 44 pins 58 are also mounted, which with the in the lock housing 56 accommodated counter pins 59 interact and through profiles 60 (Fig. 8) the key wrench 47 (Fig. 6) are adjustable.

A pin 61 is fastened to the lock nut 44 (FIG. 5) and, in addition to a locking slide (not shown), also cooperates with a release slide 63 (FIG. 3) loaded by a tension spring 62. A pin 64, which engages in the slot 65 of a switching lever 66, is riveted to the release slide 63. The switching lever 66 is firmly connected to a sleeve 67 which is freely rotatable on the release shaft 42 and whose slotted lever arm 68 acts on a pin 70 riveted to the release slide 69. On release slide 69 are rectangular recesses 71,72 ... incorporated, which serve to release the Addierwerksauswähltasten 11,12 .... The key bolts 73, 74 of the adder selection keys 11, 12 are in the starting position. . . the blocking surfaces 76,77 of the release slide 69 opposite. However, as soon as the key key 10 is inserted into the key lock, the release slide 63, based on FIG. 3, moves to the right and, with the intermediation of the switching lever 66, the sleeve 67 and the lever arm 68, moves the release slide 69 in the same direction, namely until the button pins 73 and 74 ... over the recesses 71, 72 ... are standing and thus the associated buttons 11, 12 ... are released for actuation. The release slide 63 can optionally also be designed in such a way that it only releases the control buttons 8... Assigned to the gait bank 16. The lock sockets 43 and 44 are under the action of springs, not shown, which serve to move the lock sockets and the key keys 10 and 47 cooperating therewith into the starting position when released.

According to a further exemplary embodiment, this can be done by gait bench 90 assigned key lock 80 (FIG. 10) for releasing several key groups 81 or 82 or 89 of the adder selection bank 83 or the gait bank 90 with a release slide 84 according to FIG. 11 work together. The release slide 84 is, as in FIG. 11 illustrates the pin 85 of the lock nut 86 from its normal position from to the left or through the pin 87 on the same side of the lock nut 88 moved to the right. The in F i g. 3 illustrated release slide 69 is for this purpose designed in such a way that in the normal position, both key groups 81 and 82 or 89 blocks, and in the position shifted to one side the key groups 81 and in the other position the key groups 82 of the adder selection bank 83 or the button group 89 of the gait bank 90 releases.

Of course, you can use the key lock described above 9 provided pins 38 and 61 also like pins 85 and 87 of the last described The embodiment according to FIG. 11 can be arranged on one and the same side, whereby downstream control and release means can be saved. the For this purpose, individual control spools are to be designed using suitable recesses in such a way that that the control slide associated with one lock nut is not different from the other lock nut can be influenced.

On the already mentioned release slide which can be influenced by the lock nut 43 23 (F i g. 2) a pin 92 is riveted to which a cranked lever 93 is articulated which is connected to a blocking segment 94 of the blocking device 49 stands. The locking segment 94 works together with a switch bracket 95 in such a way that that when moving the release slide 23 to the left, based on F i g. 3, the recess 96 of the locking segment 94 rotatable about the axis 97 below the Switching bracket 95 comes to rest and this, as in the German patent 964 905 set out in detail, triggers the machine gear.

In order, for example, to lock the lock nut 43 against actuation, provided that at least one of the amount keys 6, 7 has been actuated beforehand, according to FIGS. 12 and 13 a key lock device is provided. Each of the individual key banks of the amount keys 6, 7 is assigned a locking slide 98, the inclined surfaces 99 of which cooperate with the key pin 100 of the amount keys 6 and 7. The locking slide 98 is held by a tension spring (not shown) in the starting position according to FIG guided in pin-and-slot connections 101 and carries a switching pin 102 which acts on a switching extension 103 of a switching bridge 104. The switching bridge 104 is mounted on the release shaft 42, and its switching extension 105 acts on the switching extension 106 of the locking slide 107 assigned to the lock nut 43 which is guided in the pin-slot connections 108 and held in its initial position by a tension spring (not shown) according to Fig. 13. The locking slide 107 has a rectangular recess 109 which cooperates with the pin 38 of the lock follower 43. As soon as one of the amount keys, i or 7 is pressed, the locking slide 98 rotates the switching bridge 104, based on the F i g. 14 and 15, clockwise, and the switching extension 105 moves the locking slide 107 to the left, based on FIG. 13, until the recess 109 is moved out of the area of the pin 38 and thus the pin 38 when the lock follower 43 is actuated strikes the profile 110 of the locking slide 107 and the lock nut 43 blocks.

The above-described locking device not only an actuation of the lock is prevented when the pressed amount buttons 6, 7 43, but also the actuation of the amount of keys 6.7 43 suppressed in previously successful operation of the lock, since the entered into the rectangular recess 109 pin 38 a Turning the switching bridge 104 in a clockwise direction and thus a displacement of the locking slide 98 makes impossible.

(G F i. 2) with the keyboard key 47 and the cooperating lock nut 43 of the key lock 9 can be controlled at the same time amount key lock and triggered by switching of the control slide 2 6 and the associated switching mechanism 18 different machine transitions (sum total or subtotal), since the The key shafts 36 of the key keys 47 are designed differently and the control slide 26 can cover different adjustment paths due to the stops 33, 34, 35 ... As a result, various settings of the automatic adder selection and gait control means are effected in a known manner.

In contrast to this, the key buttons 10 and those that work together are used Lock nut 44, as shown in FIG. 3, only the release of the adder selection keys 11 to 14 or the key groups 81, 82 or 89.

According to a preferred embodiment of the invention is a key lock 111 (see FIGS. 14 and 15) is provided, which also has two lock nuts 112 and 113 having. At the lock sockets 112 and 113 are also vertically opposite T-shaped recesses 114,115 incorporated, their common central cross-section 116 is rectangular in contrast to the key lock 9, while the longitudinal section 117 of the lock nut 112 with the same width is somewhat longer than the opposite Longitudinal section 118 of the lock nut 113 is formed. For setting the lock nut 112 different key keys 47 according to FIG. 6 used to do so For example, adding machine aisles or machine aisles for transferring the old To trigger and control balances or to key in the account number and the like. There with the lock nut 112 machine gears are triggered and controlled, in which in As a rule, the amount keys have to be pressed beforehand, the pen 120 only works a locking slide 122 and a release slide 123, which the same functions as the locking slide 22 described above (FIG. 2) and the release slide 23. Due to the different lengths of the longitudinal cutouts 117 or 118, the key keys 47 do not fit into the recess 115 of the lock nut 113. For the lock socket 113, on the other hand, there are key wrenches 124 which can be rotated through 180 ° according to FIGS. 8 and 9, the double-T-shaped shafts 125 exhibit. On the shaft 125 are a rectangular profile part 126 and two identically designed Longitudinal profiles 127,128 and a stop limited by the central axes 129, which in one position, for example, with the stop 33 (FIG. 2) of the Control slide 26, and inserted rotated by 180 °, cooperates with the stop 34. Markings 130, 131 offset by 180 ° are incorporated on the key top.

Since the longitudinal profiles 127 or 128 when the key 124 is inserted, the pins 50 of the lock nut 112 do not fully press in and the projections 132 of the shaft 125 acting on the lock nut 113 can enter the recess 114 of the lock nut 112, the lock nut 112 remains when the used key wrench 124 in its starting position, while the lock nut 113 is transferred into its operative position. If you turn the key 124 by 180 ° and reinsert it, only the lock nut 113 is operated. According to the exemplary embodiment, the lock socket 113 is provided for machine aisles in which, for example, the final or the intermediate cross-sum is drawn from the sub-adders that are assigned to the adder selection keys 11 to 14. However, it can also be used for other selection and approval processes.

As when triggering the aforementioned total drawing machine gears no amount key may be pressed, a key lock device is necessary, as already described for the lock nut 43 according to FIGS. 12 and 13 of the previous one Embodiment has been described. The pin 133 of the lock nut 113 works for this purpose with a locking slide 134 (Fig. 14, 15, 16) together, which over the switching bridge 104 with the locking slide 98 according to FIG. 12 in operative connection stands. In addition, the pin 133 influences a locking slide 135 as well as one Release slide 136. The release slide 136 (FIG. 16) stands by means of a handlebar 137 in operative connection with the locking segment 138 of the locking device 49, which, among other things, as shown in FIG. 17, a blocking segment 141 can be seen is assigned, which is assigned by the handlebar 142 with the release slide 143 of the adder selection buttons 144 or 11 to 14 is connected. The locking segments 138 and 141 are with Provided recesses 145, 146 which work together with the switch bracket 147. The switch bracket 147 can only then enter the recesses 145, 146 and thus trigger a machine gear when both interlocking segments 138,141 through the Release slide 136 or 143 are moved into their switch-on position. Even with that Ta stenschloß 111 can use the two pins 120 and 13; on the same page to be ordered.

When the lock socket 113 is actuated, in contrast to the lock socket 112, the machine part 1 is not triggered, but only when one of the adder selection keys 144 or 17 to 14 assigned to it has been actuated. Of course, the lock socket 113 of the key lock 111 can also have one. additional facility according to F i g. 3 to enable the adder selection keys 144 or 11 to 14 or the key groups 81 or 82 according to FIG. 10 are assigned to ensure, for certain cases of need, that the adder selection keys can only be pressed when the lock number 113 has previously been brought into its operative position, in order to, in addition to the machine operations already mentioned, which differ in the operation of the manual control means, in which the lock nut 112 is triggered an engine path and controlled by the button key 47 and prepared by the lock nut 113, only the interlock mechanism 114 and the gait is selected by the inserted key button 124 and controlled Addierwerksauswahl other hand, as well as the release of the engine through one of the Addierwerksauswähltasten 144 and 11 to 14 or 81, 82 takes place, also to be able to control and enable further machine aisles by means of the key lock 111, in which, for example, the main adder is to be selected and the final or the subtotal is to be drawn from it, is for each of these machine aisles ge a special key key 150 (Fig. 14, 18 and 19), the double-T-shaped profile 151 of which is precisely adapted to the recesses 114 and 115 of the lock sockets 112 and 113. The profiles 152, 153 of the key wrench 150 and the lugs 154, 155 are designed in such a way that all counter pins 53 when the key wrench 150 is inserted, as in FIG. 14 illustrates, both lock sockets 112, 113 are pushed out of the bores 51 and the lugs 154, 155 of the key key 150 jointly transfer both lock sockets 112, 113 into their operative position.

The condition for this process is that no amount key 6, 7 has been actuated beforehand, since in this case the lock socket 113 is blocked and thus the key key 150 cannot be transferred into its operative position. In the present case, the lock socket 113 serves to act as an amount key lock, while the lock socket 112 performs the triggering function for the machine gear and the key key 150 performs the control function for the control slide 26. The key shaft 156 of the key wrench 150 cooperates with one of the stops 35 (FIG. 2) of the control slide 26, while the adjacent, unspecified stop of the control slide 26 cooperates with the key shaft of the key key provided for subtotals, which except for the offset stop in a similar manner as the key key 150 is formed.

When the key lock 111 is actuated by the key key 150 both lock sockets 112 and 113, based on FIG. 14, in their operative position transferred and their pins 120 and 133 by the locking slide 122 and 135, respectively set. The locking slide 134 locks the locking slide 98 (Fig. 12) of the amount keys 6 and 7, and the setting movements of the release slide 136 (FIG. 15) have no effect in the interlocking device 49, since none Adding unit selection button 144 or 11 to 14 is pressed. The release of the machine aisle takes place by the release slide 123 of the lock nut 112 and the control of the machine gear and the selection of the main adder by the inserted key key 150.

With a suitable design of the probe shaft profile can also be used for the aforementioned key lock 9 key keys can be used, both Actuate lock nuts 43 and 44 together. The downstream control means are for this purpose and to train the locking device 49 accordingly to the area of application also to expand this key lock significantly.
