Disc Player, and Control Method and Control Program for the Same

A method of controlling a disc player equipped with a pair of gate members that are disposed so as to be allocated to both the sides of an insertion port substantially with respect to the center of the insertion port and evacuated in a side direction of the insertion port while swung in contact with the outer peripheral portion of the inserted disc, an inserted disc inserted in the insertion port being loaded into the inside of the main body to reproduce the disc, comprising:

• a first detecting step of detecting whether a swing angle of the gate members is equal to a first swing angle or more in connection with passage of the disc;
• a second detecting step of detecting whether the swing angle of the gate members is not less than a second swing angle larger than the first swing angle in connection with the passage of the disc;
• and
• a disc diameter identifying step of identifying the diameter of a disc as a loading target on the basis of time-variation of the detection state of the first detector and the detection state of the second detector in connection with loading.

A control program of making a computer control a disc player having a pair of gate members that are disposed so as to be allocated to both the sides of an insertion port substantially with respect to the center of the insertion port and evacuated in a side direction of the insertion port while swung in contact with the outer peripheral portion of the inserted disc, a first detector for detecting whether a swing angle of the gate members is equal to a first swing angle or more, and a second detector for detecting whether the swing angle of the gate members is not less than a second swing angle larger than the first swing angle, an inserted disc inserted in the insertion port being loaded into the inside of the main body to reproduce the disc, comprising:

• detecting whether the swing angle of the gate members is equal to the first swing angle or more in connection with passage of the disc;
• detecting whether the swing angle of the gate members is not less than the second swing angle larger than the first swing angle in connection with the passage of the disc;
• and
• identifying the diameter of the disc as a loading target on the basis of the time-variation of the detection state of the swing angle in connection with the loading.
