Abstract

A magnetic recording medium processing apparatus may include a coil structured to generate a magnetic field, a magnetic field generation control part which controls generation of the magnetic field in the coil, a sensor structured to execute acquisition of predetermined information, and a sensor control part which controls execution of the acquisition of the information in the sensor. The sensor control part may request the magnetic field generation control part to stop magnetic field generation from the coil at a timing earlier by a predetermined time period than a start timing when the sensor starts the acquisition of the information, and the magnetic field generation control part may stop the generation of the magnetic field from the coil when stop of the magnetic field generation is requested by the sensor control part.

Dependent claims

A magnetic recording medium processing apparatus for use with a magnetic card, the apparatus comprising:

a magnetic field generation part structured to generate a magnetic field;
a magnetic head to read information recorded on the magnetic card inserted into the magnetic recording media processing apparatus;
a magnetic field generation control part configured to control generation of the magnetic field in the magnetic field generation part;
a sensor configured to execute acquisition of predetermined information, the sensor being different from the magnetic head;
and
a sensor control part configured to control execution of the acquisition of the information in the sensor;
wherein the sensor control part controls the sensor to periodically acquire the predetermined information and requests stop of magnetic field generation from the magnetic field generation part to the magnetic field generation control part at a timing earlier by a predetermined time period than a start timing when the sensor starts the acquisition of the information;
and
wherein the magnetic field generation control part stops the generation of the magnetic field from the magnetic field generation part when the stop of the magnetic field generation is requested from the sensor control part.

A magnetic field generation method for use with a magnetic card, the method comprising:

processing which generates a magnetic field from a coil;
processing which reads information recorded from the magnetic card inserted into a magnetic recording medium processing apparatus;
processing in which a sensor periodically acquires predetermined information different from information recorded on the magnetic card;
processing in which a sensor control part controlling the sensor requests a magnetic field generation control part which controls magnetic field generation of the coil to stop the magnetic field generation from the coil at a timing earlier by a predetermined time period than a start timing when the sensor starts acquisition of the information;
and
processing in which the magnetic field generation control part stops generation of the magnetic field from the coil when stop of the magnetic field generation is requested.
