[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a storage device for storing input means in an electronic device such as a personal digital assistant PDA, and a pen-type input means such as a touch pen.

[0002]

[Prior art]

 In electronic equipment, for example, a pen-type, ie, pressure-sensitive input device is often used for a personal digital assistant PDA, for example. An input pen, which is an input means for touching a predetermined position on the touch panel to input or display such commands, data, or other information, is usually attached to an electronic device, for example, somewhere on a touch panel of a display and operation unit. ing. For example, as shown in FIG. 1, the input pen 91 is configured such that one end of one side of the main body 92 of the rectangular PDA 9 as a storage device can be inserted into and removed from the elongated groove 921 at one end, or the length of the elongated groove 921. It is designed to be detachably fitted through the opening. The input pen 91 is detachably fitted into the long groove 921 of the PDA main body 92, so that it is easy to use. However, if the input pen 91 is repeatedly attached and detached for a long period of time, the opening of the long groove 921 becomes loose, and the input pen 91 becomes loose. Cannot be held in the groove, and it is easy to come off.

Further, as the PDA becomes more versatile, the size of the storage device such as the long groove 921 must be reduced from the viewpoint of effectively using the limited space, and the length of the input pen must be shortened. . In addition, the input pen must not be too short from the point that it can be stored in the PDA main body and the usability is improved.

FIG. 2 is a perspective view schematically showing a rectangular PDA 2 provided with a touch panel and a plurality of select buttons below the touch panel, for example, of the electronic device of the present invention, and FIG. It is an expansion schematic perspective view of a principal part. As shown in the drawing, the storage device 3 is provided in the housing body 20 of the PDA 2, along one longitudinal end surface 21, such that the opening 34 is in the short end surface 22 of the PDA housing main body 20. Have been. In the storage device 3, the position of the opening 34 is not limited as long as the position is such that the PDA is the most convenient to use. In the present invention, a PDA has been described as an example of the electronic device, but it is needless to say that the present invention is not limited to this example.

FIG. 4 is a perspective view showing a schematic disassembly of the storage device 3 in the PDA housing main body 20 (the upper half of the PDA housing main body 20 is not shown). As shown in the drawing, the storage device 3 has a housing portion 211 defined by a plurality of partitions 210 and 210 inside the longitudinal end surface portion 21 of the PDA housing main body 20 through the opening 34 by a plurality of partitions 210 and 210. The hollow cylindrical sleeve 30 is sufficient to store the input pen 4 as input means formed by combining the semi-cylindrical members 32, 32 of FIG. The partition wall 210 inside the housing portion 211 of the housing body 20 is provided with a plurality of grooves 213, 213,... A plurality of grooves 321 are provided on the outer peripheral surface of the semi-cylindrical member 32 of the sleeve 30 so as to correspond to the grooves 213, 213,. By engaging each groove 213 with the corresponding groove hole 321 while the opening 212 of the housing portion 211 of the housing body 20 grips and fits the opening 34 at the tip of the sleeve 30 of the storage device 3, the storage device The sleeve 30 is positioned and held in the accommodation section 211 of the PDA housing body 20.

In order to take out the input pen 4, which is the input means stored in the storage device 3, for example, from the small hole 20 a of the housing main body 20 to the housing portion 211, the one half cylindrical member 32 of the sleeve 30 of the storage device 3 is attached. This can be achieved by the pressing means 6 provided. Here, the pressing means 6 comprises a combination of a latch plate 61, a return spring 62 and a pressing portion 63, and allows the pressing portion 63 to be viewed through the small hole 20 a opened in the housing body 20 near the opening 34. Is provided on the semi-cylindrical member 32.

The pressing portion 63 is formed so as to straddle a flat base portion 631 fixed to the semi-cylindrical member 32 of the sleeve 30 and concave portions 361, 361 extending from the base portion 631 and recessed on the short side of the bracket 36. There are two parallel bridge portions 633, 633, and a button portion 632 provided on the tip side of the bridge portions 633, 633 for pressing the flat plate portion 614.

FIG. 5 is an exploded schematic perspective view of the pen input device 4 of the input pen of FIG. As shown, the input pen 4 has a pen shaft 40 and a pen tip 43 attached to one end of the pen shaft 40. Since the pen shaft 40 is usually formed in a small size that can be stored in the housing body 20 of the PDA 2, the pen shaft is made longer after being detached to make it easier to hold and write by hand. Here, as shown in FIGS. 5 and 6, the pen shaft 40 has a grip portion 41 for holding the pen, a plunger portion 44 extending slightly from the grip portion 41, and a plunger. A cylinder portion 46 is provided in which the portion 44 is slidably fitted along the axial direction. In the plunger portion 44, guide grooves 441 and 441 are extended and recessed along the axis from the other end near the grip portion 41 at a distance on the diameter of the outer peripheral surface. Lugs 453 and 453 are provided at the tip of the plunger portion 44 so as to protrude radially outward. At one end of the cylinder portion 46, sliding protrusions 466, 466 are formed so as to be slidable along the guide grooves 441, 441 of the plunger portion 44. Recesses 465, 465, 464, and 464 are formed at both ends of the inner peripheral surface of the cylinder portion 46 so as to correspond to the lugs 453 and 453, respectively. A ring groove 463 for engaging the pawl 613 of the latch plate 61 of the pressing means 6 is formed on the outer peripheral surface of the cylinder 46. As an ejecting means, for example, the coil spring 5 is fixed to the bottom of the sleeve 30 at the other end 51, and the pawl 6 is pressed while the one end 52 of the spring 5 is biased and compressed by the pen tip 43 of the input pen 4. 13 is locked in the ring groove 463, and the input pen 4 is stored and held in the storage device 3.

FIG. 7 is a cross-sectional view taken along the line VII-VII of FIG. 2, and FIG. 8 is a state where the pressing portion 63 in FIG. 7 is pressed, that is, when the pawl 613 of the latch plate 61 is removed from the ring groove 463. FIG. 9 is a schematic cross-sectional view of the device when the input pen 4 is ejected. Before the input pen 4 is stored in the storage device 3, first, the cylinder portion 46 is moved to the base of the plunger portion 44 of the pen shaft 40, and the lugs 453, 453 are fitted into the concave portions 464, 464. 4 is compacted, and then inserted into the storage device 3 until the pawl 613 of the pressing portion 63 engages with the ring groove 463 of the input pen 4. When the input pen 4 is ejected, the button portion 632 of the pressing portion 63 is pressed to release the pawl 613 from the ring groove 463, and the spring 5 is urged to move the input pen 4 out.

[0014]

[Effect of the invention]

 As described above, the storage device 3 is formed in a hollow cylindrical shape in the housing body 20 of the PDA, so that the input pen 4 can be stably stored in the storage device 3 and the button portion 632 can be pressed. The pen 4 can be easily taken out. Further, the input pen 4 can extend or compact the grip portion of the pen by the cylinder portion 46 sliding on the plunger portion 44 of the pen shaft 40.

Although the storage means of the input pen in the PDA of the present invention configured as described above is built in the PDA, it may be formed as a separate unit that can be easily inserted and removed so as to be easily replaced. .
