Abstract

A multi-functional USB(Universe Serial Bus) pen is provided to improve convenience of users and to reduce the cost by uniting the functions of a USB memory, a laser pointer, and a writing instrument. In a multi-functional USB pen, a body comprises lower and upper pen-handles(1,2). A writing instrument(5) is installed in the lower pen-handle. A USB memory driver(7) communicates with a USB host and transmits data to the USB host or stores data sent from the USB host. A laser pointer unit is installed in the upper pen-handle to generate a laser beam. In the laser pointer unit, a power unit is mounted in the upper pen-handle of the body to receive power from the USB host. Laser beam generating units generate a laser beam on the basis of power sent from the power unit. A lens(30) is formed at one end of the upper pen-handle to convert the laser beam generated by the laser beam generating unit, into the parallel light and emit the parallel light to the outside. A switch(40) turns on/off the laser beam generating unit.

The present invention relates to a pen, and more particularly, to a USB flash memory pen having a laser pointer function.

In all recent available mobile storage devices, the purpose of movement has not been substantially achieved. For example, an externally mounted hard disk, an externally mounted engraving and recording device, a ZIP, a MO, etc. are large in memory and inconvenient to carry. These devices provide large storage capacities but are not suitable for movement. When these devices are used as a portable memory, for example a soft disk, they occupy a large space in the drive device which is specifically utilized, and the energy consumption is large and the noise becomes large. Since the operating speed of the soft disk drive is slow, the storage space is small, and the data storage device is not reliable. Unlike the unstable characteristics of magnetic media as storage media, soft disks are portable products, and physical shocks are easily found. Therefore, existing memory has not been substantially applied. A portable read-write memory having a USB interface has been proposed that can overcome the above drawbacks.

On the other hand, the laser pointer is used as a device for indicating a portion that needs to be explained using a laser light in a meeting or briefing. Such a laser pointer is compact and is more convenient to carry and convenient to use than a conventional indicator rod, and thus has recently been used in various ways in place of the conventional indicator pupil.

However, in the related art, since the portable read-write memory, the laser pointer, and the writing instrument are separately provided, the portable read-write memory, the laser pointer, and the writing instrument must be carried separately.

Accordingly, an object of the present invention is to provide a USB flash memory pen in which a laser pointer function is implemented in a USB flash memory pen.

In order to achieve the above object, the present invention is a main body consisting of a lower pen and an upper pen; Writing instruments installed in the lower pen stand; A USB memory driver in communication with a USB host, the USB memory driver transferring data to or storing data from the USB host; And a laser pointer unit installed inside the upper pen holder to generate a laser beam.

Preferably, the USB memory driver is connected to a USB port of a USB host to interface control and user data with the USB host, that is, to exchange data at high speed, and to receive power from the USB host through the USB port. USB interface to supply each component; A flash memory for storing the user data and outputting the stored user data; And a control unit controlling an operation of the US interface and the flash memory.

More preferably, the laser pointer unit is installed inside the upper pen of the main body to receive power from the USB host; A laser beam generator for generating a laser beam based on the power from the power source; A lens formed at one end of the upper pen holder to convert the laser beam generated by the laser beam generating unit into parallel light and diverge it to the outside; And a switch for turning on / off an operation of the laser beam generator. Most preferably, the multifunction USB pen further includes a USB connection lamp for blinking the connection state of the upper pen holder and the USB host.

Hereinafter, a multifunction USB pen according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded view showing the configuration of a multi-function USB pen according to a preferred embodiment of the present invention. 2 is a cross-sectional view of the multi-function USB pen shown in FIG. 3 is an explanatory diagram of the external operation of the multifunction USB pen shown in FIG. 1. 4 is an exploded view of the upper and lower pen stand of the multi-function USB pen shown in FIG.

The USB flash memory pen according to the preferred embodiment of the present invention includes a main body, a writing instrument 5, a USB memory driver 7, and a laser pointer unit 28.

The main body consists of an upper pen holder 1 and a lower pen holder 2.

The writing instrument 5 is installed inside the lower pen holder 2.

The USB memory driver 7 communicates with a USB host (not shown), such as a PC or PDA, and transfers data to or stores data from the USB host.

After first penetrating the pen nib 4 through the spring 5, the upper half can be inserted into the pen holder hole 31 of the lower pen holder pedestal 3. The lower portion of the lower pen holder pedestal 3 consists of a bolt portion 32 and a bolt hole 11 at the inner edge of the lower pen holder 2, wherein the bolt portion 32 of the lower pen holder pedestal 3 is the lower pen holder 2. Can be fixed by blocking the inside of the bolt hole 11 (see FIG. 2). When turning the bolt portion of the lower pen holder pedestal 3 downward, the lower pen holder pedestal 3 simultaneously presses the spring 5, and the pen nib 4 exits the lower pen holder 2 by the pressing pressure (Fig. 3). If the lower pen holder base 3 is turned, the nib 4 becomes smaller in the lower pen holder 2 again. The upper edge of the lower pen rest pedestal (3) has an internal thread (33), the characteristics of which are as follows.

The USB connector 7 and the bushing 6 are integral, and the lower edge of the bushing 6 has an external thread 61, which is the internal thread of the lower pen rest pedestal 3. In combination with the 33, the lower pen stand 1 and the upper pen stand 2 have a single main body as a whole.

As shown in Fig. 4, when connecting the USB connector 7 into the USB port (not shown) of the computer (not shown), simply turning the upper pen holder 1 will cause the upper pen holder 1 to be in a fixed position. The lower USB connector 7 is to be separated from within the support hole of the lower pen holder pedestal 3.

The laser pointer unit 28 is installed inside the upper pen holder 1 of the main body to generate a laser beam.

The laser pointer unit 28 includes a power supply unit 22, a laser beam generator 24, a lens 30, and a switch 40.

The power supply unit 22 is installed inside the upper pen holder 2 of the main body to receive power from the computer. The laser beam generator 24 generates a laser beam based on the power from the power supply unit 22. The lens 30 is formed at one end of the upper pen holder 1 to convert the laser beam generated by the laser beam generator 24 into parallel light and emit it to the outside. The switch 40 turns on / off the operation of the laser beam generator 20.

FIG. 5 is a block diagram illustrating an example of the USB memory drive shown in FIG. 1.

The USB memory driver 7 has a USB interface 510 and a flash memory 520. And a controller 530.

The USB interface 510 is connected to a USB port (not shown) of a USB host (not shown) such as a personal computer or a PDA to interface control and user data with the USB host, that is, to exchange data at high speed. Power is supplied from the USB host through the port to each component. The flash memory 520 stores the user data and outputs the stored user data. The controller 530 controls the operations of the US interface 510 and the flash memory 520.

Multifunction function USB pen according to a preferred embodiment of the present invention further includes a USB connection lamp 50 for blinking the connection state of the upper pen holder 2 and the PC ().

When the upper pen holder 1 is connected to the USB host, the USB connection lamp 50 lights up red.

As described above, according to the present invention, by simultaneously integrating the USB memory function, the laser pointer function, the writing instrument function, there is an advantage that can be very convenient for the user and can also reduce the cost.
