PURPOSE:To simplify the mechanism and to ensure the retrieval, by constituting the device with n sets of selection bars, selection mechanism moving the card by one pitch, and clock bar to block the movement of card latched. CONSTITUTION:The selection bars of 2s, 21, 22, 24, 27 are provided in lifting free in the case of device 4. The selective mechanism has permanent magnet which can absorb the side of magnetic part of the card, and it is provided in moving free by one pitch of card tooth horizontally and it is moved sequentially by one pitch with the drive mechanism not shown. The lock bar group 3 can be lifted up individually and located in the pitch of code tooth of the card by (card code digit-1). This bar is sequentially lifted up from the right in the process of card selection and it latches with the card latch to block the movement of the latched card toward right. When the code of card to be retrieved is input at the operation table 7, the operation of selection bars 2s...27, lock bar 3 and the selection mechanism 5 can continuously be made. |
