CROSS-REFERENCE TO CO-PENDING PATENT APPLICATIONS 
     This Nonprovisional Patent application is a continuation-in-part of Provisional Patent Application No. 61/175,949, filed on May 6, 2009 by inventor Hector Martinez hereby incorporated by reference in its entirety and for all purposes, to include claiming benefit of the priority data of filing of Provisional Patent Application No. 61/175,949. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates to the field of biological waste and toxic material collection and management. The present invention more particularly relates to the collection and transfer of solid waste and toxic material. 
     BACKGROUND OF THE INVENTION 
     Solid waste and solid toxic materials are generated from many sources, to include by production and evacuation from animals as well as industrial processes. Farm laborers, zoo workers and pet owners are not unusually tasked with cleaning up waste matter or from the ground or otherwise deposited by animals, such as canines, cats, domesticated animals and/or animals maintained in confined areas. 
     Yet touching feces is almost universally repulsive and considered to be a degrading and undesirable act. The prior art includes efforts to maintain separation between a collector of animal waste or toxic matter and the material to be collected. 
     To solve the above stated problem it has been proposed to collect the pet&#39;s excrement by means of small shovels, placing the depositions into bags that when closed are discarded into any street or public trash collector. 
     U.S. Pat. No. 6,059,332 discloses a domestic pet&#39;s excrement collector. The invented collector includes two similar rectangular structures facing each other and joined in between by a posterior concave-convex wall forming a pincer-shaped hinge for the collector. Over the convex face of the wall is fixed a cylindrical tube closed at one end, having inside of the tube a roll of continuous bags, while the other end of the tube is closed by a lid. The plastic bag is placed covering the collecting pincers. The bottom of the bag is contained within the pincers towards the cylindrical tube. This complex construction does not relate to the present invention. 
     U.S. Pat. No. 7,523,972 discloses a portable waste remover with integrated bag. The invented waste remover includes a handle, a housing portion for holding and dispensing bags, and a grabbing assembly actuated by a spring and pulley assembly contained in the handle. The grabbing assembly is further coupled to a first and second frame member wherein the frame members are capable of pivotally attachment to the housing portion. The first and second pivot arms may have removable clamps that either secure the frame members for grabbing waste or detach from the frame members making them collapsible. The housing portion may be configured in the shape of a tube with a roller and having a slotted groove disposed where disposable bags may be fitted around the roller and dispensed through the slotted groove. In another configuration, the grabber assembly engaging the handle is comprised of a button, spring, spring arm with shoulder, and toothed elongated arm engaging the frame members. 
     There is a long-felt need to provide a device that optimally enables a human to collect animal solid waste, or other solid toxic material, without requiring the device operator to handle or touch the solid material. 
     None of the mentioned prior-art patents offers a construction similar to this present invention, nor provide a solution having a low cost base structure or frame including a movable arm, to which is attached a disposable plastic bag within which the pet&#39;s depositions are collected, such as disclosed herein. Once the bag has been used, the bag may be withdrawn in a rapid and hygienic manner. 
     SUMMARY OF THE INVENTION 
     This and other objects of the present invention are made obvious in light of this disclosure, wherein a device is provided for collecting and bagging solid waste is provided. According to a first device, a first arm and a second arm are coupled with a lever, wherein at least one arm is slidably coupled with the lever. A bag may be positioned in an open position when the first arm is located distally from the second arm, and the bag may be closed by a device user manipulating the arms towards each other. 
     The first device may optionally include a motor that provides mechanical force applicable to drives the arms towards and/or away from each other. Additionally or alternatively, an optional spring or springs may be attached to the arms or lever to drive the arms towards and/or away from each other. 
     In alternate devices, the mechanical force applied to drive the arms towards and/or away from each other may be translated to one or both arms by a chain or a cable element. 
     In still alternate devices, plate, a pole and/or a handle may be coupled with the arms. The plate is positioned relative to the arms to stabilize the waste or toxic material for insertion into the bag. The pole and/or handle may be configured to reduce or eliminate the degree of bending required by the device user during the process of collected waste or toxic material. 
     In certain alternate variations, the bag may include paper, plastic, recycled plastic, vegetable matter and/or cellulose. Alternatively or additionally, the bag further includes an internal adhesive proximate an aperture of the bag. 
     In certain still alternate variations, the bag maintains a barrier between the device and keeps the waste material from contaminating or touching the device. A handle for the device may allow the user to collect and package the waste material in a bag without directly touching the waste material. Soiling of the user&#39;s hands, skin, footwear or clothing by the waste can thus be avoided. 
     The foregoing and other objects, features and advantages will be apparent from the following description of aspects of the present invention as illustrated in the accompanying drawings.

     Referring now to  FIG. 6  is a schematic diagram of electromechanical aspects of the scooper  24  of  FIGS. 2-5 . An electric battery  50  provides electrical power to an electromagnet assembly  52  and a control circuit  54 . The control circuit  54  is coupled to the control button  38  and the control circuit  54  is configured to cause the electromagnet to spin a magnet  56  of a circular gear  58  to rotate in either a clockwise or a counter clockwise rotation in reference to rotation about the Y-axis. 
     The battery  50 , the electromagnetic assembly  52 , the control circuit  54 , the magnet  56  and the circular gear  58  are coupled to the housing  30 . 
     The circular gear  58  engages with a plurality of teeth  60  of the lever  32 , thereby translating the rotational motion about the Y-axis of the circular gear  58  into linear motion along the X-axis. The resultant linear motion of the lever  32  along the X axis causes the arm  26  to move toward or away from the plate  28 , whereby the scooper translates to and from open position as illustrated in  FIGS. 2 and 3  and to the closed positioned of  FIG. 4 . 
     One or more elements  50 - 60  of the scooper  24  consist of, or comprise, a magnetized metal, aluminum, iron, stainless steel or other suitable metal, metal alloy or material known in the art.

     The control, button  38  is a three position control that the user  44  manually positions in an off state, a second state and a third state. When the control button  38  is in the off state the control circuit  54  either electrically disconnects or fails to electrically connect the battery  50  to the electromagnet assembly  52 . When the control button  38  is in the second state, the control circuit  54  electrically connects the battery  50  to the electromagnet assembly  52  and/or directs the circular gear  58  to rotate in a first rotational direction about the Y-axis that causes the lever  32  to extend out from the housing  30  along the X-axis, and thereby position the arm  28  in the open position. disconnects or fails to electrically connect the battery  50  to the electromagnet assembly  52 . When the control button  38  is in the third state, the control circuit  54  electrically connects the battery  50  to the electromagnet assembly  52  and/or directs the circular gear  58  to rotate in a second rotational direction about the Y-axis that causes the lever  32  to move into the housing  30  along the X-axis, and thereby position the arm  28  in the closed position. 
     The circular gear  58  may be rotatably coupled to a fixed axle  61 , wherein the axle  61  is coupled with housing  30  and a magnet field generated by the electromagnet assembly  52  acts upon the magnet  56  to drive the magnet  54  around the axle  61  and thereby cause the circular gear  58  to rotate about the axle  61 . The circular gear  58  engages with the teeth  60  of the lever  32  as the circular gear  58  rotates and thereby drives linear motion of the lever  32 . 
     Alternatively the circular gear  58  may be driven as controlled by the control circuit  54  and by a Kinmore™ electric toy motor model number KM-16T050 as marketed by Shenzhen Kinmore Motor Co. Ltd. of Nanshan District, Shenzhen, Guangdong, People&#39;s Republic of China. 
     Referring now to  FIG. 7  is a perspective view of the scooper  24  of  FIGS. 2-6  in a travel position, wherein the arm  26  and the plate  28  are each positioned to align substantially parallel to an X-Y plane defined by the X-axis and the Y-axis. The positioning of the arm  26  toward the X-Y plane orientation is facilitated by the arm hinge assembly  34 , and the positioning of the lever  28  toward the X-Y plane orientation is facilitated by the plate hinge assembly  36 . An optional manual handle  62  further increases the ease with which the scooper  24  may be transported. 
     Referring now to  FIG. 8  is a schematic of a second alternate variation of the present invention of  FIGS. 1-6  wherein a spring-actuated mechanism is provided. A spring  64  is coupled to the housing  30  by a spring guide  66 . The spring guide  66  is coupled to the housing at a first guide point  66 A and a second guide point  66 B. A trigger  68  is rotatably coupled to the housing  30  by a rotational coupling  70 , and may be rotated to maintain the arm  26  in the open position of  FIGS. 2 and 3 . The spring  64  directs a spring force to the arm  26  to cause the arm  26  to move along the X-axis and toward the plate  28  and to assume the closed position of  FIG. 4 . The user  44  manually rotates the trigger  68  by pressing the trigger end  72  in the up or down direction. Pressing the trigger end  72  in the up direction causes the trigger to enable a maintenance of the arm  26  in the open position of  FIGS. 2 and 3 . Pressing the trigger end  72  in the down position causes the trigger  68  to rotate and to enable the spring  64  to drive the arm  26  towards the plate  28  and form the closed position of  FIG. 5 .
