In the conventional stacker, when accumulating media, the media is temporarily stored in a media temporary holding plate in a cash-in / pay-out unit up to a hold allowable value, and then transferred to the stacker side. The length of the sensor detecting member provided on the back surface of the stage, which is detected by the sensor disposed between the unit and the stacker, is longer than the allowable holding value, and a wasteful space that does not contribute to the accumulation of media must be provided in the stacker. There was a point. SUMMARY OF THE INVENTION It is an object of the present invention to provide a stacker which does not need to provide a useless space for stacking media even when the length of a sensor detecting member provided on the back surface of the stage is equal to or longer than a medium holding allowable value.

[0006]

In order to achieve the above object, in a stage mechanism of a stacker according to the present invention, a sensor detecting member is pivotally supported by a stage so as to rotate, and a biasing member is used. It is urged to protrude toward the bottom of the stacker.

[0007]

When the stage configured as described above approaches the bottom of the stacker, the sensor detecting member abuts the tip of the bottom of the stacker and faces the back surface of the stage while resisting the urging force of the urging member. And the stage returns to its original position when it leaves the bottom of the stacker. Therefore, according to the present invention, even if the length of the sensor detecting member provided on the back surface of the stage is equal to or more than the medium holding allowable value, it is not necessary to provide a useless space in the stacker that is not useful for medium accumulation.
