The controller controls the driving unit such that the entering unit enters into the storage bag supported by the supporter and comes in contact with the sheet stored in the storage bag to detect an upper end position of the sheet stored in the storage bag. ## Claims ### Claim 1 A sheet storage apparatus for storing a sheet in a storage bag having an opening for inserting the sheet comprising: a supporter configured to support a portion of the storage bag in the vicinity of the opening of the storage bag; an entering unit configured to move between a predefined standby position which is a position above the storage bag supported by the supporter and a predefined lower end position where the entering unit is in the storage bag supported by the supporter; a driving unit configured to move the entering unit from the standby position to the lower end position; a first detector configured to detect whether or not the entering unit is located at the lower end position; a platform configured to move in a substantially vertical direction and on which at least a part of the storage bag supported by the supporter is placed; and a controller configured to control the platform to move downward, when it is not detected by the first detector that the entering unit is located at the lower end position, such that an upper end position of the sheet stored in the storage bag supported by the supporter is maintained at a predetermined height. ### Claim 2 (depends on 1) The sheet storage apparatus according to claim 1, further comprising a stopping mechanism configured to stop the entering unit from moving toward the lower end position, when the entering unit comes in contact with the sheet stored in the storage bag before the entering unit reaches the lower end position. ### Claim 3 (depends on 1) The sheet storage apparatus according to claim 1, wherein the entering unit enters into the storage bag supported by the supporter and pushes the sheet stored in the storage bag downward. ### Claim 4 (depends on 1) The sheet storage apparatus according to claim 1, wherein the controller also detects a height of the sheet stored in the storage bag supported by the supporter. ### Claim 5 (depends on 4) The sheet storage apparatus according to claim 4, further comprising: a second detector configured to detect a position of the platform, and wherein the controller detects the height of the sheet stored in the storage bag based on the position of the platform detected by the second detector. ### Claim 6 (depends on 1) The sheet storage apparatus according to claim 1, further comprising a pantograph configured to expand and contract in the vertical direction, wherein the entering unit is attached to the lower end of the pantograph, and the driving unit drives the pantograph to contract such that the entering unit is moved to the standby position and to expand such that the entering unit is moved to the lower end position. ### Claim 7 (depends on 6) The sheet storage apparatus according to claim 6, further comprising a torque limiter between the driving unit and the pantograph, wherein when an excessive torque higher than a predetermined torque is applied to the torque limiter, the driving unit and the pantograph are disconnected from each other. ### Claim 8 (depends on 6) The sheet storage apparatus according to claim 6, wherein the driving unit includes a motor, the first detector includes a detection plate configured to rotate in synchronization with the motor, an upper end detection sensor and a lower end detection sensor, when the pantograph fully contracts and the entering unit is located at the standby position, the detection plate is detected by the upper end detection sensor, and when the pantograph fully expands and the entering unit is located at the lower end position, the detection plate is detected by the lower end detection sensor. ### Claim 9 A sheet storage apparatus for storing a sheet in a storage bag having an opening for inserting the sheet, comprising: a supporter configured to support a portion of the storage bag in the vicinity of the opening of the storage bag; an entering unit configured to move between a predefined standby position which is a position above the storage bag supported by the supporter and a predefined lower end position where the entering unit is in the storage bag supported by the supporter; a driving unit configured to move the entering unit from the standby position to the lower end position; a first detector configured to detect whether or not the entering unit is located at the lower end position; a storage bag position adjuster configured to move the position of a bottom portion of the storage bag supported by the supporter in a substantially vertical direction; and a controller configured to control the storage bag position adjuster to lower the bottom portion of the storage bag, when it is not detected by the first detecting unit that the entering unit is located at the lower end position, such that an upper end position of the sheet stored in the storage bag supported by the supporter is maintained at a predetermined height. ### Claim 10 A sheet storage method for storing a sheet in a storage bag having an opening for inserting the sheet comprising: supporting a portion of the storage bag in the vicinity of the opening of the storage bag by a supporter; storing the sheet in the storage bag supported by the supporter; moving an entering unit for pressing the sheet from a predefined standby position which is a position above the storage bag supported by the supporter to a predefined lower end position where the entering unit is in the storage bag supported by the supporter; detecting whether or not the entering unit is located at the lower end position; and moving the platform downward, when it is not detected by the first detector that the entering unit is located at the lower end position, such that an upper end position of the sheet stored in the storage bag supported by the supporter is maintained at a predetermined height.
