  • the device according to the present invention is designed for selectively drawing a desired card out of a plurality of cards 11, 12, 13 19 which have longitudinally (in the left to right direction as viewed in FIG. 1) elongate iron pieces 1 10, 120, at the front edges and notches 111, 121, 131 191 in the rear upper edges (in FIG. 1, the right side is referred to as front and the left side as the rear) respectively.
  • the iron pieces 110, 120 190 respectively provided on each card may be the same shape and may be provided on the cards at different positions from each other, or alternatively may be of the type having two or more projections with the positions of the projections being varied between the cards.
  • the position or positions of the projection or projections of one card is or are differentiated from the position or positions of the projection or projections of the other cards.
  • the iron pieces are not necessarily made of iron but may be of any material which is magnetically attractive.
  • nickel pieces or pieces of other materials are generally called iron pieces.
  • a hook member 1 is arranged above the card and is moved upwards or downwards electrically for engagement with or disengagement from the notch 111 formed in said card.
  • the hook member 1 is operated with the timing to be described later, to hold the card against movement.
  • the notch 111 may obviously be formed at the rear lower portion of the card depending upon the location of the hook member operating mechanism.
  • the set of electromagnets A1 A10 may be substituted by one longitudinally elongated electromagnet, but in the description herein reference is made to an arrangement in which 10 separate electromagnets are provided.
  • the set of card drawing electromagnets 2 is operated by a motor in such a manner that it makes a reciprocal movement towards and away from the cards, and upon completion of its onward stroke, the set of electromagnets is located in a position close enough to attract the iron pieces. It is preferable from the viewpoint of simplification of the mechanism that the set of electromagnets is moved at an equal speed on both the onward and return strokes.
  • a plurality of card stoppers 3 are provided at right angles to the card drawing direction, i.e. the moving direction of the card drawing electromagnets Al A10, and may be reciprocated to prevent the drawal of the cards.
  • the card stoppers 3 are longitudinally reciprocated by stopper operating members (41 410) in the leftward or rightward direction as viewed in FIG. 4.
  • the stopper operating members 4 respectively have one end thereof engaging a respective card stopper 3 and the other end swingably held by a frame 5 for swinging motion in a counterclockwise direction, as viewed in FIG. 28, under the effect of electromagnets B.
  • each of the stopper operating members 4 is biased in a direction opposite to the attracting direction of the electromagnet B, by a leaf spring 50 which is secured at its root portion.
  • each stopper operating member 4 moves the corresponding card stopper 3 to the right as viewed in FIG. 4, only for the period when the associated electromagnet B is energized.
  • the electric circuit of the electromagnets A, B, C is as shown in FIG. 5.
  • the electromagnets B and C are constantly connected in parallel and the electromagnets A and B are electrically connected such that Al and B1, A2 and B2, A and B10 can be switched over. Therefore, A1 and B1 will not be concurrently energized.
  • a switch 6 for A and B is so arranged that the connection will be switched, for example, from B3 to A3 when a signal representative of 3 is fed.
  • the circuit connecting the electromagnet C in parallel with the electromagnets A or B is turned on and off by a relay R.
  • the relay R is of the type that it is closed by one ON-OFF operation of a microswitch S2 and cut off by another ON-OFF operation of the same.
  • This microswitch S2 is arranged such that it is turned on and off twice by a microswitch operating member 7 during one reciprocal motion of the electromagnets 2, i.e. once during the onward stroke and once during the return stroke of said electromagnets 2.
  • the microswitch operating member 7 is secured to the electromagnets 2 as shown in FIG. 1.
  • Another microswitch S1 is provided in side-by-side relation with the microswitch S2, on the side closer to the cards. The position of this microswitch S1 is such that said microswitch 81 will be turned on only when the electromagnets 2 are held closest to the iron pieces on the cards.
  • the electromagnets 2 are energized with a strong magnetic attractive force upon the actuation of the microswitch 81.
  • the following operation can be obtained by actuating the respective electromagnets with a predetermined timing.
  • FIG. 6 shows a diagram illustrating the timed operational relation of the respective elements, in which the abscissa axis represents time.
  • the chart at the upper portion of FIG. 6 shows the operation of the electromagnets 2, with the ordinate axis representing distance.
  • character X designates the rightward distance from the tip end of the iron piece.
  • the electromagnets 2 start to move towards the right and the microswitch S1 is turned off.
  • the magnetic force of the electromagnet A3 is somewhat weakened when the microswitch S1 is turned off and continuously draws the card 13 is continuously drawn to the right.
  • the magnetic force of the electromagnet is instantaneously intensified as stated above, for the purpose of positively drawing the card while overcoming the static friction between the card 13 and the adjacent cards (see FIG. 2B).
  • the relay R is deenergized, so that the electromagnets B and C are deenergized and the card stoppers 3 are moved to the left as viewed in FIG. 4.
  • the hook member 1 is lowered to hook the cards.
  • the card 13 is not hooked as it has been drawn by the length of the iron piece 131. Therefore, the card 13 only is drawn out incident to the rightward movement of the electromagnets 2 (see FIG. 3B).
  • a card having a specific code only can be selected and drawn out, by feeding a signal representative of said code externally to the device by means of the push-button or the like.
  • the device of the invention can be applied to an automatic microfiche retrieval device by Combining it with a microfiche reader, and also to a data card retrieval device.
  • a card retrieval device for selectively drawing a plurality of cards, each said card including, at the front edge thereof, an iron piece having a longitudinally extending projection and, at the rear side edge thereof, a notch, said device comprising a plurality of movable members selectively projected to or retracted from the position of said iron piece to prevent the drawal of a card; electromagnets which are movable towards the cards to a position close enough to magnetically attract an iron piece and movable in the opposite direction; and a hook member which is normally held in engagement with said notches but disengages therefrom only for the period when said movable members are in operation.
  • control means which controls the operational timing of the respective members in such a manner that said hook member is disengaged from cuit including a plurality of microswitches and the operation of said electromagnets is associated with said microswitches.
  • a card retrieval device wherein the number of said movable members is greater than the number of the cards to be retrieved.
