  • Such a playing means 14 may be formed of conventional manner, so that explanation of manner for controlling the playing means is omitted from the below illustration of the control means.
  • the control means 16 includes three electrically connected contact makers 88, 89 and 90 attached on the back surface of the each case 27, said contact makers being cooperated with stational contact points 92 to 99 formed on a plate 91 positioned above the passing line of the case. Said contact makers 88 and 90 are adapted to contact with the contact points 92 and 99 and other contact maker 89 being cooperated with any one of contact points 93 to 98. A number of contact points 93 to 98 are equal to that of cases 27, and the position of contact maker 89 of the each case is different from that of other cases so that the contact maker 89 is contacted with appropriate point of the contact points 93 to 98.
  • a group of push switches 101 to 106 are connected to the points 93 to 98, respectively, that is, the switch 101 to the point 93, the switch 102 to the point 94, the switch 103 to the point 95, the switch 104 to the point 96, the switch 105 to the point 97 and the switch 106 to the point 98.
  • a group of said push switches are of the type of alternative selective switch, and the latter being formed so as to change connections between a power source A and any one of the points and between the power source A and a flip flop circuit F ,F.
  • the flip flop circuit is arranged in such a manner that when the pulse dispatched from senses formed on the cartridge tape to detect each end of individual play and all plays is entered through a switch 108 for one track or a switch 109 for four track, connection to ground is set into OFF condition, and when the contact point 92 on the plate 91 is grounded by contacting of the contact maker 88 through the contact point 99 the said OFF condition is reset into ON condition whereby the connection to ground is usually maintained ON condition when there is no input pulse from the senses.
  • the push switches 101 to 106 are adapted to actuate a relay .110 having a switch 111.
  • both poles of the motor 36 are shorted to stop immediately the motor and to prevent conduction electromotive force generated from the motor to the relay 112 when the switch 114 is changed into OFF condition.
  • output from the power source is connected with a relay 115 and switches 1 17 and 1 18 of the relay 115 via a diode 116.
  • the relay 115 is adapted to rotate the motor 62 clockwise and counterclockwise direction. That is, in ON condition of the relay 115 the motor is rotated in positive direction or clockwise direction whereby the carrying member 67 moves from the playing means 14 to the case 27, and in OFF condition, rotation of the motor 67 and motion of the carrying member 27 are vice versa.
  • the limit switch 120 is adapted to return the playing cartridge to the appropriate case 27 when the main switch 119 is chenged into Off condition during playing condition.
  • the control circuit is shown reproducing condition of the cartridge 12 selected by the push switch 101. Now, in case of other a cartridge, for example, as cartridge corresponding to the push switch 102 is desired, the switch 102 is pushed in and changed into OFF condition.
  • the push switch 101 to 106 areformed of the type of alternative selective switch,;the'push switch 101 is automatically chenged into ON condition bymanipulation of the push switch 102 and therelay 110 being chenged into OFF condition to switch the switch 111 the carrying member 67 from the playing means 14 to the case thereby transporting the cartridge 12 in the playing means 14 to the case 27.
  • thelimit switch 72 is changed ON condition by action of the rear edge of the cartridge 12 in the carrying member, sothat the relay 112 and the switch 1 14 are changed into ON condition. This connects output from the limit switch 72 with the motor 36 to rotate the latter whereby the case 27 having the cartridge 12 is moved with rotation of the chains 25 and 26.
  • the limit switch 30 is relieved from contact with the second cam 34 whereby the switch 30 is chenged into ON condition. Then, the case 27 corresponding to the switch 102 is moved to the plate 91, and the contact makers of the case 27 are come into contact with the appropriate contact point 94 and the contact point 99 of the plate 91, forming electrical connection between the contacts 94 and 99. This energizes the relay 110 to change the switch 111 for cutting off vconnection to the limitswitch 72. However, the limit switch 72 is connected with the power source via the limit switch 30 thereby maintaining moving action of the case 27.
  • the limit switch 30 When the case.27 is reached to predeterminate position, the limit switch 30 is changed into ON condition by the case 27 to cut off the connection between the power source and the limit switch 72, thereby stopping the motor 36 with the case 27 Simultaneously, the power source is connected with the limit switch 71 through the switch 111 in the relay 110. As the limit switch 71 is in the state of no contact with the carrying member 67, the power source is connected with the switches 1'17 and 118 in the relay 115 via the limit switch 71. But the relay 115 maintains its OFF condition by virtue of the diode 116 thereby rotating the motor 62 to reverse direction.
  • the carrying member 67 performs supply of cartridge 12 corresponding to the push switch 102 to the playing means
  • the limit switch 71 is actuated by the carrying member 67 thereby stopping the motor 62. Therefore, the selected cartridge 12 is maintained in the playing means whereby the reproduction of the cartridge 12 may be performed.
  • a plurality of tape cartridge can be reproduce automatically and in predetermined sequence. In this case, all the push switches 101 to 106 are changed into the flip flop circuit 107, and the switch 108 or the switch 109 is changed into 'ON condition to enter pulse from the senses in the cartridge tape into the flip flop circuit 107.
  • the relay 1 is changed into OFF condition, so that, as well as above mentioned manner, carthe contact maker 88 of the next case having cartridge r to be subsequently played comes into contactwith the contact point 92 of the plate 9l,'the flip flop circuit 107 is reset to form a grounded condition whereby the relay 110 is changed into ON condition.
  • movement of the case is stopped and the next cartridge is inserted into the playing means 14 by the carrying member 67 toreproduce the cartridge.
  • the above cycle is automatically repeated thereby performing reproduction of a plurality of the cartridges in predetermined sequence.
