Abstract
An information writing device is used to write information on a card such as magnetic card. Information to be written on a card is manually fed into the device through a keyboard. The card may be reciprocated through a driving unit to write information thereon during its forward stroke and to read out the information during its backward stroke. The information read out is collated with the input one to visually indicate resulting coincidence or non-coincidence thereof.
Claims18
An information writing device comprising;
- a roller which moves the card on which is to be written information;
- a motor to drive said roller;
- keyboard which feeds information input that is to be written on said card;
- a shift register which memorizes the input information;
- first switch which detects the initiation of forward movement of said card;
- second switch which detects the finish of forward movement of said card;
- a motor controller which causes said motor to rotate in the direction of forward movement of said card upon receipt of the output signal of said first switch and causes said motor to rotate in the direction of backward movement of said card upon receipt of the output signal of said second switch;
- a mode selector which selects the shifting direction of information in said shift register responsive to the output signals of said first and second switches;
- a read head which reads out the synchronizing signals recorded on said card;
- a read-write head which writes information on said card and reads out information from said card;
- a selector which selects the state of said read-write head depending on the output signals of said first and second switches;
- means which applies said synchronizing signal to said shift register depending on the selection of said mode selector to produce information from said shift register;
- means which collates the information read out by said read-write head with the information produced by said shift register;
- and
- means which display the collating.

An information writing device comprising:
- reciprocating means for reciprocating a card, on which is to be written information, along a card guide line;
- memory means for storing information to be written on said card;
- instructing means for detecting the card moving forward along said card guide line to instruct said memory means to provide the information being stored in the memory means;
- writing means for writing the information extracted from said memory means on said card while said card is being moved forward along said card guide line by said reciprocating means;
- reading out means for reading out the information having been written on the card by said writing means, while said card is being moved backwardly along said card guide line by said reciprocating means;
- and
- collating means for collating the information read out by said reading out means with the information being stored in said memory means.
