Abstract When a magnetic card having two recording zones is inserted into a magnetic card drive device for a read/write operation of each recording zone, a magnetic card generation indicator lights an indicator lamp after a predetermined period of time following a first insertion of the magnetic card, turns ON and OFF the lamp upon pulling out of the magnetic card from the magnetic card drive device, lights the indicator lamp again after a predetermined period of time following a second insertion of the magnetic card, and puts out the lamp upon pulling out of the magnetic card. By lighting, turning ON and OFF and putting out of the indicator lamp, it is possible to prevent mishandling of the magnetic card having two recording zones to ensure the read/write operation of the both recording zones and timely pulling out of the magnetic card from the magnetic card drive device.
A magnetic card generation indicator for a magnetic card drive device which is provided with a head for reading data from or writing data in one of two recording zones of a magnetic card, comprising: detecting means for detecting whether the insertion of the magnetic card into the magnetic card drive device is a first or second insertion; delay means for providing a predetermined delay time after the insertion of the magnetic card; an indicator lamp; and control means for controlling the indicator lamp by the outputs of the detecting means and the delay means to light, put out and turn ON and OFF the indicator lamp.

A magnetic card generation indicator for a magnetic card drive device which is provided with a head for reading data from or writing data in one of two recording zones of a magnetic card, comprising: detecting means for detecting whether the insertion of the magnetic card into the magnetic card drive device is a first or second insertion; delay means for providing a predetermined delay time after the insertion of the magnetic card; an indicator lamp; and control means for controlling the indicator lamp by the outputs of the detecting means and the delay means to light, put out and turn ON and OFF the indicator lamp.
Claim 3
Dependent Claim
49 words
A magnetic card generation indicator according to claim 1 wherein the control means delays lighting of the indicator lamp at the time of the first insertion of the magnetic card and delays putting out of the indicator lamp at the time of the second insertion of the magnetic card.
Claim 4
Dependent Claim
82 words
A magnetic card generation indicator according to claim 1 wherein the control means lights the indicator lamp after a predetermined period of time following the first insertion of the magnetic card, turns ON and OFF the indicator lamp upon pulling out of the magnetic card from the magnetic card drive device, lights the indicator lamp after a predetermined period of time following the second insertion of the magnetic card and puts out the indicator lamp upon pulling out of the magnetic card.
