Card reader protecting device

A protecting device for card reader equipment in which information on a recording medium such as a card and the like is read, comprising:

• an aperture portion provided in a passage of the recording medium and adapted to lead said recording medium to said card reader equipment;
• detecting means for detecting a normal material in said recording medium and developing an electrical output signal responsive to the detection thereof, said detecting means being disposed in the passage of the recording medium before said aperture portion with respect to a forward transporting direction of said recording medium;
• shutter means for inhibiting the recording medium from passing through said aperture portion when no output signal is developed by said detecting means, said shutter means being disposed in the passage of the recording medium after said aperture portion with respect to the forward transporting direction of said recording medium;
• control means for controlling said shutter means to permit said recording medium to pass through said aperture portion when said detecting means detects the normal material in said recording medium, and to inhibit said recording medium from passing through said aperture portion when said detecting means does not detect the normal material in said recording medium;
• and
• holding means for developing a hold signal to be applied to said control means to hold such a state that said control means permits said recording medium to pass through said aperture portion as long as said recording medium is placed upon said shutter means.

A protecting device for card reader equipment in which information on a recording medium such as a card and the like is read, comprising:

• detecting means for detecting a normal material in said recording medium and developing an electrical output signal responsive to the detection thereof;
• shutter means provided in a passage of the recording medium for inhibiting the recording medium from passing therethrough when no output signal is developed by said detecting means;
• control means for controlling said shutter means to permit said recording medium to pass through a station, in which said shutter means is provided, when said detecting means detects the normal material in said recording medium, and to inhibit said recording medium from passing through said station in the passage of the recording medium when said detecting means does not detect the normal material in said recording medium;
• holding means for developing a hold signal to be applied to said control means to hold such a state that said control means permits said recording medium to pass through said station in the passage of the recording medium as long as said recording medium is placed upon said shutter means;
• and
• temporary holding means for holding the output signal from said detecting means for a predetermined time at least until said holding means develops its output signal.

• detecting means for detecting a normal material in said recording medium and developing an electrical output signal responsive to the detection thereof;
• shutter means provided in a passage of the recording medium for inhibiting the recording medium from passing therethrough when no output signal is developed by said detecting means;
• first control means for controlling said shutter means to permit said recording medium to pass through a station, in which said shutter means is provided, when said detecting means detects the normal material in said recording medium, and to inhibit said recording medium from passing through said station in the passage of the recording medium when said detecting means does not detect the normal material in said recording medium;
• holding means for developing a hold signal to be applied to said control means to hold such a state that said control means permits said recording medium to pass through said station in the passage of the recording medium as long as said recording medium is placed upon said shutter means;
• means for delaying the output signal from said detecting means by a predetermined time;
• means for disenabling said delay means to operate responsive to an output signal from said holding means;
• and second control means for controlling said shutter means to inhibit said recording medium from passing through said station in the passage of the recording medium responsive to an output signal from said delay means.

• holding means for developing a hold signal to be applied to said control means to hold such a state that said control means permits said recording medium to pass through said station in the passage of the recording medium as long as said recording medium is placed upon said shutter means;
• first sensing means for sensing that said shutter means is pressed by the recording medium in the passage;
• second sensing means for sensing that said first sensing means is developing its sensing output while said detecting means is not developing an output signal;
• and
• alarm means responsive to the sensing output of said second sensing means for developing an alarm signal representing that the normal material is not present in said recording medium.

• means for delaying the output signal a predetermined time longer than the predetermined holding time of said temporary holding means;
• means for disenabling said delay means to operate responsive to an output signal from said holding means;
• and
• second control means for controlling said shutter means to inhibit said recording medium from passing through said station in the passage of the recording medium responsive to an output signal from said delay means.
