Control device with electrical purchase inspection, in particular for Leiirprograanae.

The Keuarun ^ concerns a control device, in particular aur Control of the solutions put in programmed lessons Tasks.Zirie such control should aara learners even without enable permanent presence of a teacher, seise solutions to check for correctness. This is "especially important for the major cn fail ranked by teaching programs, in which the learners different Work through areas of knowledge independently and systematically should.

Is are known, i'rage and answer games in which punched Stencils a large number of questions and answers in addition to ohirn are applied, the stencils on an unchangeable iContaktfeld are placed and correct answers are bound by ¥ er can be determined by two related contacts this case creates a circuit across the contacts, a battery and a lightbulb closed, which lights up the lightbulb. The known arrangement, however, has the compartment part that the After a relatively short time, the end of the game knows where the ζ us a. ^ .. i related Xontakte lie. The well-known game is therefore less suitable for teaching purposes.

The control system consists of an electrical control device By checking that a base plate (1) bit has an up- Gabenfeld and a uosungsfeld for cards to be placed optionally or the like is provided, so that each unit has a large number of stationary Contacts are assigned, each of which has a task contact and a solution contact are connected to one another in a concealed manner, and that every ^ Auf ^ abenEaJfeemit is provided with contacts, which when hanging up of the card pre-determined: had to have fixed task contacts in the to

Switch on the control circuit. In one embodiment The fixed contacts consist of a point contact and a spring contact separate from it, which either through card contact or through a control means, e.g. a pin can be connected to each other.

To explain the innovation in more detail, an exemplary embodiment is described below with reference to the drawing. This shows in Fi & A a base plate 1 with a task field 2 and a solution field 3 · 3θει task field 2 is assigned a variety of contacts 4,5, ο, which are next to each other one side edge of the task field are arranged, in the drawing on the lower edge. In the same V / eise the solution field 3 solution contacts 7,8,9 are assigned, here on the linear side edge 10. Each task contact 4,5,6 .. is with A corresponding solution contact 7, 8, 9 connected. The task contacts are arranged concealed under a cover 11 in such a way that one is placed on the task with the task or tasks. Or the like. Provided task card vorbeotinate stationary contacts 4,5,6 are effectively switched through. This is done, for example, because on the lower edge of the task card 12 connected zone contacts 15 are provided on the upper and lower sides, which are caused by the position of the contacts 13 when the JLufgabeiikarte is placed or inserted into the contact row 4, 5, 5 The card 12 select pre-ordered contacts 4,5, -S.Me stationary Eontaiite ^, 4,5, ο each have a fixed point contact 14 and a firing contact 15, which are separated from each other in the idle state. Preferably, all are resilient Contacts 15 of a series of contacts made from a Sxick, which has a KaniriarTlges appearance. The celebrating contacts 1 i> are connected via a dashed line 1b with a B & tterie 17, the other pole via a G-lahoirne 18 with the correspondingly designed resilient contacts 19 the contact row 7,8,9 is connected. The IContc -.-: t row 7, & _S S is arranged under a height of openings 20 of the base plate 1 or an öesondersn cover, so that pressure from the outside, e.g. By means of a pen, marker pen or a fixed pushbutton, the resilient contact 19 can be printed on the corresponding point contact. Unfortunately, for the exact placement of the task and solution cards on the corresponding ones

these are provided with guide strips 21. To simplify the removal process for the cards, the G-run plate is 1 for each of the fields, 2,3 with a flat one protruding into the fields Deep / Ver see. The contact 13 mounted on the task card is either a U-shaped metal strip placed around the edge Or an Ilet pressed through the card, but can also go through Staples can be formed or produced using printing technology. The stationary pump contacts can be one on the base plate be attached and. connected to each other by individual lines However, when the cone is finished it will be useful to use the connecting lines print on a printed circuit board (etch or similar) and insert the point contacts into the circuit board Pail can lay the point contacts from pressed into the plate best, which can be bent in one operation if necessary be able.

The Konxrolxeinriohtuzig described so far acts as follows The Aufo ^ benfeld a Aufgcibenkarte 12 is placed or inserted so that its lower edge between the talking ** contacts 15 and the point contacts 14. This means that all contacts are apart separated, which are not connected to one another by card contacts 13 The learner now reads the text on the card and finds some passages left out, which he has written on a special sheet of paper must note the text on the card. Once this task has been solved, the itö * - sungsblatt aur aas .uosun ^ sfeld 3 laid, with now next to the hole line 20, among other things, are the correct solutions. Is now replaced by the correct solution corresponding opening a pin inserted and soüit If the contact arrangement 7, 6 or 9 is actuated, the light bulb lights up 13 on.

The expression is not limited to the series of contacts are unfortunately only arranged on one side edge of the two. fe.an Äanii can also have the two parts of the fixed contacts next to each other arrange, train both parts as point contacts, ie as immovable contact parts, with the card contact 13 then only lies on one side of the card and bridges both contact parts, the required contact pressure can then be created, for example, that one or more panels after placing the card under Spring pressure on the edge of the card · 'snapped'.

The control system can also protect against a premature search for the correct solution ^: .verden by inserting a switch in the street noon, which is only operated when a piece of paper containing the solutions from the learner or the like is inserted into an additional field, This can also be done by placing a strip of paper over the solubility field, which can be scribed and which only releases the additional contact when it is removed. With such an arrangement, it is also possible to use a CJ lightbulb row instead of the rows of contacts 7, 8, 9 to provide where "in the intestine after removing the paper strip the additional contact closes the Stroiakreis and immediately indicates the correct solution by lighting up the relevant field Paper emerges and closes the stroke path. However, it can also be actuated by turning ung the holle on which a supply of paper is wound.

Such an example is shown in Fig. 2. This shows a Additional writing field, which is combined with the base plate 1 or designed as a separate component is arranged above and below the writing field and Ie a hollow 22,25.Holle is provided as a take-up roll iait a handle 24. The shaft of the Holle 23 is a lock 25 and an additional contact 26 arranged. The lock prevents reverse rotation of the roller, u-id after half a further turn. The contact 26 is after! every half a Brenimg switched through besw blocked. Above that movable paper strip is a transparent plate (Deckisl) arranged a penster to: n List the correct answer Dobals the hell 23 the answer under the transparent one Has transported plate, the contact 26 is switched through, the operre prevents reverse rotation. The correct answer is provided by the activated Jlohoirne is marked. If the learner has the! question wrong answered, carries; he got the correct answer after-When moutertransport If the contact is blocked again, the G-lübimehen (s) expire again the next question can be asked and answered. With separate training of the additional writing field this 2weekly with plugs or conductors to the electrical ¥ er-LUBiS-old the base plate.
