     BACKGROUND OF THE INVENTION 
     Modern development in checkout systems for use in certain department store and supermarket operations includes the use of a reader in the form of a data pen or wand for optically or magnetically reading data on coded labels attached to the merchandise items purchased by the customer. The data pen is scribed across the label thereby either optically or magnetically sensing the coded indicia and generating electrical signals representing the indicia sensed. These electrical signals are transmitted over a communication cable attached to the data pen to a control unit where the signals are decoded and the resulting data assembled, displayed and printed. During the checkout operation, the operator is required to perform other operations which do not involve the use of the data pen such as receiving and dispensing money, coupons, etc. During these operations, the operator will store the data pen in a holder until the next reading operation is to occur. 
     Since the checkout environment varies with each store installation, it has been found that a data pen holder which has been designed for a horizontal installation for use in one type of checkout environment could not in many instances be used in another store environment where the holder is required to be installed in a vertical position. In this latter instance, due to limited space availability, etc., the data pen within the vertically mounted holder may extend out at such an angle as to interfere with the movement of the checkout operator. Therefore, there has developed a need for a data pen holder which can be mounted in either a horizontal or vertical position wherein the data pen will be orientated in each position at an angle which is convenient for its removal and insertion by the checkout operator, and wherein the angular extension of such data pen in each instance will not be in the way of either the checkout operator or customer. In addition, the use of a data pen requires that any foreign material picked up by the tip or deposited in the socket be removed. The location of electronic equipment associated with the data pen must of course also be considered. It is, therefore, an object of the present invention to provide a data pen holder which can be mounted in either a horizontal or vertical position, each position supporting the data pen at an angle convenient to the operator. Another object of this invention is to provide a data pen holder which is constructed to handle dirt and other objects falling into the socket when the holder is in either the horizontal or vertical position. A further object of this invention is to provide a data pen holder which is constructed to provide storage area for associated electronics equipment. A still further object of this invention is to provide a data pen holder which is simple in construction, made of a low cost material and convenient for diassembly and assembly with a minimum of tools required. 
     SUMMARY OF THE INVENTION 
     In order to fulfill these objects, there is provided a data pen holder comprising a hollow base segment constructed to support electronic equipment for use with the data pen. Releasably mounted to the base segment is a housing assembly including a hollow support segment having a supporting surface orientated at a first predetermined angle with the lower surface of the base segment. Releasably mounted to the supporting surface of the support segment is a housing segment containing a cone-shaped storage socket extending along an axis which is at a second predetermined angle with the lower edge of the housing segment. The housing segment is mounted to the support segment in a first position to orientate the storage socket at a desirable angle with the lower surface of the base member when the holder is in a horizontal position. This desirable angle is equal to the sum of the first and second predetermined angles above described. When the holder is to be mounted in a generally vertical direction, the housing segment is mounted to the support segment 180° from its first position which orientates the storage socket at a second desirable angle with the lower surface of the base member for the storing and retrieving of the data pen by the operator. This second desirable angle is equal to the difference between the first and second predetermined angles above described. Located within the base segment is a raised opening extending through the bottom surface of the base segment. When the housing segment is in either of its two mounted positions, the lower end of the storage socket, which is open, will be located within the raised opening to permit disposal of any dust or other dirt collected on the operating head portion of the data pen or other objects deposited in the socket.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring now to FIG. 1 of the drawing, there is shown an oblique view of the holder of the present embodiment which comprises an assembly generally indicated as 20 consisting of a housing segment 22, a support segment 23 and a base segment 24. Located in the front wall portion 25 of the housing segment 22 is an aperture 26 within which may be positioned the instrument which is to be supported by the holder. In the present embodiment, a light pen 27 for optically reading bar code indicia is positioned within the aperture 26 and extends outwardly from the aperture 26 at an angle with the base segment 24 which is convenient for handling by the user or operator. A communication cable 28 is attached to the rear of the light pen 27 and is mounted within the base segment 24. As will be described hereinafter, the holder 20 of the present invention is capable of being mounted in a horizontal or vertical position. The holder 20 is shown in FIGS. 1 and 4 in the horizontal position while FIGS. 2 and 3 illustrate the holder mounted in the vertical position. 
     As shown more particularly in FIGS. 5, 6 and 7, the base segment 24 consists of a one piece flat tray-like member preferably molded of any suitable type of plastic material, such as a high impact styrene, and having side walls 30, 31 and a raised center portion 32 which forms a slot 33 extending lengthwise of the bottom surface 34 of the base segment. 
     Formed as part of the center portion 32 is a rectangular-shaped hollow neck portion 35 having a slanted top opening 36 which extends through to the slot 33 in the bottom surface 34 of the base segment 24. Extending from the side of the neck portion 35 is an L-shaped support member 37 (FIG. 6) which may be used as a support for electronic equipment associated with the light pen 27. The holder 20 of the present embodiment includes a speaker for generating a signal whenever a valid reading of the data on the label is obtained by the light pen, a potentiometer for adjusting the volume of the signal and a quick disconnect member for releasing the communication cable 28 from the holder 20. The support member 37 may be utilized in supporting the potentiometer. 
     Located adjacent the front edge of the neck portion 35 and formed as part of the center portion 32 is an upstanding baffle member 38 for supporting the speaker and a front upstanding snap action fastening portion 40 for use in attaching the base segment 24 to the support segment 23. Located at the rear of the neck portion 35 and formed as part of the center portion 32 is an upstanding boss 41 supporting a screw member 39 or other type of a fastening member for mounting a support member such as a ring or clip 49 or the like to the base segment 24 for supporting the holder 20 from a vertical surface. Located at the left end of the center portion 32 (FIG. 5) is a rear overhang portion 42. In a manner that will be described more fully hereinafter, the fastening portion 40 and the overhang portion 42 function to releasably secure the support segment 23 to the base segment 24. 
     The support segment 23 is formed of a plastic material similar to the base segment 24 and comprises a hollow housing having a sloping top supporting edge portion 43 (FIGS. 1 and 5), a rear edge portion 44 and a front edge portion 45, the latter including a recessed portion 46 (FIG. 1) having a plurality of louvers 47 which allows communication with the inside of the support segment 23 for use in disengaging the base segment 24 from the support segment 23, as will be described more fully, hereinafter. As shown in FIG. 5, the bottom edge 48 of the recessed portion 46 of the support segment 23 extends in a rearward direction while the rear portion 44 of the support segment 23 includes a vertically extending mounting surface 50 having a lower rib portion 51 extending in a horizontal direction. In mounting the support segment 23 to the base segment 24, the rib portion 51 of the support segment 23 is first inserted beneath the overhang portion 42 of the base segment 24. The front edge portion 45 of the support segment 23 is then pressed down against a front wall 52 of the fastening portion 40 of the base segment 24 resulting in the bottom edge 48 of the recessed portion 46 bending the wall 52 rearwardly until the edge 48 is beneath the wall 52, at which time the wall 52 will snap back over the edge 48 to the position shown in FIG. 5, thus fastening the support segment 23 to the base segment 24. 
     Extending across the top and adjacent the front and rear edges of the support segment 24 are a pair of recessed mounting surfaces 53, 54 (FIGS. 3, 5 and 7), each having an aperture 55 which will accommodate a screw member 63 or the like for use in mounting the housing segment 22 to the support segment 23, as will be described more fully hereinafter. The housing segment 22 is formed of the same plastic material and in the same manner as the base segment 24 and support segment 23 and comprises a hollow housing member which includes a sloping top 56, identical sides 57 and the front wall portion 25 (FIGS. 1 and 5), the latter having formed therein a frusto-conical shaped socket portion 60 for supporting the light pen 27. The socket portion 60 extends from the opening 26 (FIG. 1) inwardly at a predetermined angle with respect to the lower edge of the housing segment 22 (FIGS. 3 and 5). The front 61 and rear 62 edges of the housing segment 22 are secured to the mounting surfaces 53, 54 (FIGS. 5 and 7) of the support segment 23 by means of the screw members 63 or the like. 
     The present invention contemplates orientating the socket portion 60 and the top supporting edge 43 of the support segment 23 at predetermined angles with a horizontal plane to provide an entry angle of the light pen into the socket portion 60 which is convenient to the checkout operator when the holder is mounted either in the horizontal or vertical position. The invention further contemplates the positioning of the lower end of the socket portion 60 within the confines of the opening 36 of the neck portion 35 when the holder is in either the horizontal or vertical position to allow dirt or other foreign substances picked by the light pen in reading the labels to drop through the neck portion 35 and out of the holder 20 itself. 
     In accordance, thereof, with the present invention, the socket portion 60 is arranged at an acute angle with respect to the lower edge of the housing segment 22. As shown in FIG. 5, this angle is 35°. The top supporting edge 43 of the support segment 22 is sloped at a 15° angle with the base line of the support segment 23. Thus, when the segments 22 and 23 are mounted in the position shown in FIGS. 1 and 4, where the holder 20 is to be positioned on a horizontal surface, the entry angle of the light pen is 50° with respect to the lower surface of the base segment 24. 
     On the other hand, when the holder 20 is to be mounted in the vertical direction, the support segment 23 is separated from the base segment 24 by inserting any convenient instrument through the louvers 47 (FIGS. 1 and 7) and thereby engage and move the front wall member 52 of the fastening member 40 in a rearward direction. This movement will dislodge the wall member 52 from engagement with the edge 48 of the recessed portion 46 and allow the support segment 23 to be removed from the base segment 24. The screw members 63 are then removed, followed by the housing segment 22 being rotated 180° and then secured again as so repositioned (FIG. 3) to the support segment 23 by means of the screw members 63. In this instance, as illustrated in FIG. 3, the front 61 and rear 62 edges of the housing segment 22 are positioned reversely from that as described previously; that is, being now secured to the mounting surfaces 54 and 53, respectively. After again securing the support segment 23 to the base segment 24 in the manner described previously, the holder is ready to be mounted to a vertical surface by any suitable mounting means such as the clip member 49 (FIG. 5). This vertical position of the holder 20 is shown in FIG. 2. In this position the entry angle of the light pen is 20° with respect to the lower surface of the base segment 24 -- being the difference between the above referenced socket angle and support segment top edge angle. As shown in FIG. 3, when the holder 20 is in the vertical position, the lower end of the socket portion 60 is still positioned within the opening 36 of the neck portion 35. By sloping the front edge 64 of the neck portion 35, it will be seen from FIG. 3 that any dirt or other debris falling from the light pen 27 or otherwise into the opening 26 will be deposited through the slot 33 of the base segment 24 where it will fall to the floor. 
     While a preferred entry angle of the light pen has been given when mounted in a horizontal or vertical position, it is obvious that the light pen can be orientated at other acute angles without departing from the instant invention. The lateral configuration of the opening 36 of the neck portion 35 is controlled by the orientation angle of the socket 60 and therefore may be varied in accordance with the design of the socket 60, the socket being preferably within the opening when holder 20 is in either the horizontal or vertical position. 
     As described previously, for simplicity and cost savings reasons, the preferred embodiment of the holder assembly is directed to having each of the component segments formed by any well-known plastic molding process utilizing the properties and the configuration of the plastic material for assembling the segments without the use of other fastener means. While the outer configuration of the segments and the holder have been shown to be generally wedge-shaped, it is obvious that the invention can be utilized with any shaped segments while still functioning for the intended purpose as disclosed in the present invention. 
     While the principles of the invention have now been made clear in the illustrated embodiment, it will be obvious to those skilled in the art that many modifications of structure, arrangements, elements and components can be made which are particularly adapted for specific environments and operating requirements without departing from these principles. As an example, while the holder 20 is shown mounted in a vertical position, it is obvious that the holder can be mounted in a position other than vertical and still come within the present invention. In addition means other than the clip 49 can be used to mount the holder to the supporting surface. The appended claims are therefore intended to cover any such modifications within the limits of the true spirit and scope of the invention.
