Housing bottom 5 has a screw boss 157 with a screw hole 159 for receiving captive screw 146 to firmly and releasably attached battery door 11 to pocket driver tool 10.

FIGS. 25 and 26 illustrate illumination device actuating button 9. Illumination device actuating button 9 has a generally oblong outer periphery with straight opposing sides 162, and a flat exterior face 161. It has a peripheral shoulder 163 on a lip 165 for engaging an interior shoulder on housing top 3 to retain button 9 in housing top 3. There is an interior recessed cross 167 for engaging button protrusion 141, which button 9 depresses to engage PCB-LED assembly 99 with cell batteries C to actuate LEDs 137.

Driver stalls 111, 113, 115 and 117 extend across driver tool compartment 8 perpendicular to longitudinal axis 11. The base of compartment 8 is the interior surface of the forward portion of housing bottom 5, and the top of compartment 8 is the interior surface of front face 53 of tool door 7. Driver tools found to be important to users of this type of tool are a flat head driver 169, a relatively large Phillips head driver 171, a relatively small Phillips head driver 173 and an Allen driver 175. The preferred forms of drivers other than a flat head driver are a #2 Phillips driver 177, a #1 Phillips driver 179 and a 5/32 inch Allen driver 175. These drivers are preferably 24.85 mm long. The driven end of each of drivers 169, 171, 173 and 175 are each preferably hexagonal as is socket 21, and have a cross dimension between the flats of 6.250 mm. Socket 21 is dimensioned to receive and drive drivers 169, 171, 173 and 175. The respective drivers 169, 171, 173 and 175 each have a multisided driver end dimensioned and configured to be received in socket 21 in a fitting relationship. One of drivers 169, 171, 173 and 175, when received in socket 21, is used to drive a fastener by the manual rotation of pocket driver tool 10 about longitudinal axis L. The fitting relationship prevents the rotation of the driver with respect to multisided socket 21.

A tool magnet 181 is provided at an interior closed end of socket 21 in order to releasably hold ferromagnetic drivers 169, 171, 173 and 175, respectively, held in socket 21. The foregoing drivers can easily be removed from storage compartment 8 and held in socket 21, and likewise be removed from socket 21 by the user of pocket tool 10.

Housing bottom 5 is attached to housing top 3 by means of housing screws 183 which are inserted in screw holes in each of screw bosses 33 and 35 in housing top 3, and screw bosses 129 and 131 in housing bottom 5. A quick clip 185 or other key ring can be inserted through key ring orifice 27.

Pocket driver tool 10 is extremely flat and hence easy to store. Battery compartments 95 hold cell batteries C in a general plane parallel with the flat faces 12 and 53 of housing top 3 and tool door 7, and flat face 77 of housing bottom 5, with their imaginary central longitudinal axes in an imaginary plane perpendicular to an imaginary plane incorporating longitudinal axis L and perpendicular to flat faces 12, 53 and 77. Drivers 169, 171, 173 and 175 extend across tool compartment 8, and are short enough as described above to render pocket driver tool 10 to have a short width between side walls 15 and 17. Since parts to be held by pocket driver tool 10 are the latter drivers, and since their respective widths are of a small dimension as noted above, the thickness of tool 10 is also small enough to assist in making tool 10 easy to store. Likewise the length of tool 10 between opposing curved end walls 19 and 25 is very small as well. In the preferred embodiment of the invention, pocket driver tool 10 has a width w of 33.133 mm (or about 1.3 inches), a length l of 65.237 mm (or about 2.6 inches) and a thickness t of 6.350 mm (or about 0.4 inch).

Pocket driver tool 10 is also effective in use. Even though its width is small, a user can insert a driver in socket 21, insert the driver in a screw or other fastener, hold the opposing side walls 15 and 17 with the thumb on one side and index finger on the other side and apply torsion to tool 10 to obtain the desired twisting action. Curved side walls 15 and 17 assist in preventing slipping of the fingers along the latter walls during use. Actuating button 9 can be easily operated with one of the user's fingers while pocket driver tool 10 is in use, possibly requiring an easy manipulation of the user's fingers.

Pocket driver tool 10 is a precision tool, which nevertheless can be made inexpensively for a current retail selling price of less than ten dollars (US). Pocket driver tool 10 is attractive in appearance, and effective and efficient in use.

The invention has been described in detail with particular reference to its preferred embodiment, but variations and modifications within the spirit and scope of the invention may appear to those skilled in the art from the foregoing description and from the appended claims.
