Claim 5

A copy storage tray assembly for storing copy paper sheets in a copy storage tray, which is provided with a detection means for detecting the presence of said copy paper sheets at the time of supply of said copy paper sheets to said copy storage tray, comprising: a front regulating plate for regulating, in a direction of supply of said copy paper sheets to said copy storage tray, a position of a leading edge of each of said copy paper sheets stored in said copy storage tray, said front regulating plate movably provided so as to be displaceable both in the direction of supply of said copy paper sheets to said copy storage tray and in an opposite direction to said direction of supply of said copy paper sheets, so as to accordingly displace therewith said respective copy paper sheets; copy paper detection means provided in an opening formed at a central portion of said front regulating plate for detecting the presence of said copy paper sheets; and an actuator means for displacing said front regulating plate in said direction of supply of said copy paper sheets to said copy storage tray and in said opposite direction, whereby at the time when each of said copy paper sheets has been supplied to said copy storage tray and is detected by said detection means, said front regulating plate is displaced by said actuator means in said direction opposite to said direction of supply of said copy paper sheets to said copy storage tray so as to displace each of said copy paper sheets to a predetermined position such that each of said copy paper sheets is no longer detected by said detection means.

Claim 6

A copy tray assembly as in claim 3, wherein said actuator means includes a rack gear secured to said front regulating plate, a pinion gear in mesh with said rack gear and a motor for driving said pinion gear.

Claim 7

A copy storage tray assembly for storing copy paper sheets in a copy storage tray, which is provided with a detection means for detecting the presence of said copy paper sheets at the time of supply of said copy paper sheets to said copy storage tray, comprising: a pair of side regulating plates for regulation in a lateral direction positioning of said copy paper sheets stored in said copy storage tray; a movable detection means provided within at least one of said side regulating plates so as to project between said pair of side regulating plates to detect the presence of said copy paper sheets at the time of supply of said copy paper sheets to said copy storage tray, which detection means is displaceable to a retracted position such that said copy paper sheets are not detected by said detection means; and an actuator means for displacing said detection means to said retracted position; whereby as each of said copy paper sheets is supplied to said copy storage tray, said actuator means temporarily displaces said detection means to said retracted position and then, returns said detection means to a detection position for detecting the next one of the copy paper sheets.

Claim 8

A copy storage tray assembly for storing copy paper sheets in a copy storage tray, which is provided with a detection means for detecting the presence of said copy paper sheets at the time of supply of said copy paper sheets to said copy storage tray, comprising: a pair of side regulating plates for regulation in a lateral direction positioning of said copy paper sheets stored in said copy storage tray; a movable detection means provided within at least one of said side regulating plates so as to project between said pair of side regulating plates to detect the presence of said copy paper sheets at the time of supply of said copy paper sheets to said copy storage tray, which detection means is displaceable to a retracted position such that said copy paper sheets are not detected by said detection means; and an actuator means for displacing said detection means to said retracted position; whereby as each of said copy paper sheets is supplied to said copy storage tray, said actuator means temporarily displaces said detection means to said retracted position and then, returns said detection means to a detection position for detecting the next one of the copy paper sheets.

Claim 9

A copy storage tray assembly as in claim 5, wherein said actuator means is a solenoid.

Claim 10

A copy storage tray assembly for storing copy paper sheets in a copy storage tray, which is provided with a detection means for detecting the presence of said copy paper sheets at the time of supply of said copy paper sheets to said copy storage tray, comprising: a pair of U-shaped cross-sectional side regulating plates for positioning said copy paper sheets in said copy storage tray both of which are movable so as to be displaced in their respective lateral directions; detection means provided on an upper face of at least one of said side regulating plates so as to detect when a copy paper sheet is supplied to said copy storage tray from above said copy storage tray, a lower face of said copy paper sheet being brought into contact with said detection means; and actuator means for displacing each of said side regulating plates in said respective lateral directions whereby, at a time when each of said copy paper sheets has been supplies to said copy storage tray and is detected by said detection means, said side regulating plates are displaced in said lateral directions by said actuator means so as to displace each of said copy paper sheets in a vertical direction to a predetermined position such that each of said copy paper sheets is no longer detected by said detection means, following which said side regulating plates are returned medially by said actuator means to their initial position which is set to the width of a copy paper sheet.

Claim 11

A copy storage tray assembly for storing copy paper sheets in a copy storage tray, which is provided with a detection means for detecting the presence of said copy paper sheets at the time of supply of said copy paper sheets to said copy storage tray, comprising: a pair of U-shaped cross-sectional side regulating plates for positioning said copy paper sheets in said copy storage tray both of which are movable so as to be displaced in their respective lateral directions; detection means provided on an upper face of at least one of said side regulating plates so as to detect when a copy paper sheet is supplied to said copy storage tray from above said copy storage tray, a lower face of said copy paper sheet being brought into contact with said detection means; and actuator means for displacing each of said side regulating plates in said respective lateral directions whereby, at a time when each of said copy paper sheets has been supplies to said copy storage tray and is detected by said detection means, said side regulating plates are displaced in said lateral directions by said actuator means so as to displace each of said copy paper sheets in a vertical direction to a predetermined position such that each of said copy paper sheets is no longer detected by said detection means, following which said side regulating plates are returned medially by said actuator means to their initial position which is set to the width of a copy paper sheet.

Claim 12

A copy storage tray assembly as in claim 7, wherein said actuator means includes a rack gear secured to said at least one side regulating plate, a pinion gear in mesh with said rack gear and a motor for driving said pinion gear.
