The invention of claim 1 wherein the restraining element includes a bar having a given weight, and the restraining means includes interconnecting means interconnecting the bar with the tray such that the weight of the bar will move the bar over the area of the opening to place the restraining element into the closed position.
- 4. The invention of claim 3 wherein the interconnecting means includes at least one link and pivot means connecting the link between the bar and the tray such that upon placement of the tray in the second position, the bar will be biased by gravity and the link will pivot to place the bar over the area of the opening.
- 5. The invention of claim 1 wherein the document holder includes a base, and the orienting means includes mounting means for mounting the tray on the base for movement relative to the base between the first and second positions of the tray, and prop means for propping the tray in the second position thereof upon the base.
- 6. The invention of claim 5 wherein the mounting means includes swinging means for enabling swinging of the tray relative to the base about a generally vertical axis along a path extending from a central position toward either one of a left position left of the central position and a right position right of the central position.
- 7. A document holder for holding documents in the form of a stack of individual sheets selectively viewable from a viewing location forward of the stack, while being maintained in the stack, the sheets each having a length and a width defining a prescribed area, the document holder comprising:
- a tray having a receptacle for receiving the stack of sheets, the receptacle including an opening through which the sheets are passed into and out of the receptacle, the opening having an area great enough relative to the area of each sheet to be received within the receptacle so as to enable essentially uninhibited passage of the sheets through the opening into and out of the receptacle;
- orienting means on the tray for enabling the tray to be moved between a generally horizontal first position, wherein the opening is oriented generally horizontally and faces upwardly, so that the sheets may be dropped essentially downwardly through the opening into the receptacle, and a generally vertical second position, wherein the opening is oriented generally vertically and faces forward so that the sheets in the stack will confront the viewing location; and
- restraining means on the tray adjacent the opening, the restraining means including at least one restraining element movable between an open position, wherein the restraining element is adjacent the opening outside the area of the opening for enabling unrestricted passage of the sheets through the opening into and out of the receptacle, and a closed position, wherein the restraining element overlaps the area of the opening for restraining passage of the sheets through the opening out of the receptacle, and gravity-biased means for moving the restraining element into the closed position in response to placement of the tray in the second position; and wherein
- the restraining element includes a bar having a given weight, and the restraining means includes interconnecting means interconnecting the bar with the tray such that the weight of the bar will move the bar over the area of the opening to place the restraining element into the closed position;
- the interconnecting means includes at least one link and pivot means connecting the link between the bar and the tray such that upon placement of the tray in the second position, the bar will be biased by gravity and the link will pivot to place the bar over the area of the opening; and
- the tray includes opposite sides spaced apart horizontally and extending generally vertically when the tray is in the second position so as to be sloped forwardly, relative to the generally horizontal orientation of the tray in the first position, and the bar extends longitudinally generally parallel to one of the opposite sides and is displaced laterally upon movement of the tray between the first and second positions of the tray as a result of the forward slope of the one of the opposite sides of the tray.
- 8. The invention of claim 7 wherein the restraining means includes one said bar and corresponding interconnecting means associated with each of the opposite sides of the tray.
- 9. The invention of claim 7 wherein the gravity-biased means includes further means for moving the restraining element into the open position in response to placement of the tray in the first position, the further means including slope means establishing a rearward slope in the sides of the tray, relative to the generally horizontal orientation of the tray, when the tray is in the first position, such that the bar is biased by gravity laterally out of the area of the opening upon movement of the tray to the first position.
- 10. The invention of claim 9 wherein the restraining means includes one said bar and corresponding interconnected means associated with each of the opposite sides of the tray.
- 11. A document holder for holding documents in the form of a stack of individual sheets selectively viewable from a viewing location forward of the stack, while being maintained in the stack, the sheets each having a length and a width defining a prescribed area, the document holder comprising:
- a tray having a receptacle for receiving the stack of sheets, the receptacle including an opening through which the sheets are passed into and out of the receptacle, the opening having an area great enough relative to the area of each sheet to be received within the receptacle so as to enable essentially uninhibited passage of the sheets through the opening into and out of the receptacle;
- orienting means on the tray for enabling the tray to be moved between a generally horizontal first position, wherein the opening is oriented generally horizontally and faces upwardly, so that the sheets may be dropped essentially downwardly through the opening into the receptacle, and a generally vertical second position, wherein the opening is oriented generally vertically and faces forward so that the sheets in the stack will confront the viewing location; and
- restraining means on the tray adjacent the opening, the restraining means including at least one restraining element movable between an open position, wherein the restraining element is adjacent the opening outside the area of the opening for enabling unrestricted passage of the sheets through the opening into and out of the receptacle, and a closed position, wherein the restraining element overlaps the area of the opening for restraining passage of the sheets through the opening out of the receptacle, and gravity-biased means for moving the restraining element into the closed position in response to placement of the tray in the second position; and wherein
