Description

  The present invention is a safety device for an optical mouse, and in particular has a shielding mechanism for the optical mouse, and when the optical mouse leaves the work surface, it cuts off the optical signal of the infrared controller of the optical mouse by itself.

  With the advancement of computer software and the spread of graphical user interfaces, mice are already widely used in computer user interfaces. Conventional mice are generally mechanical mice, and when the ball rolls, the X-axis and Y-axis shutter wheels are moved, and the optical signal of one light emitter is intermittently cut off from the shutter wheels, via a photodetector. The direction of movement of the mouse can be determined by processing with an appropriate control circuit. Furthermore, by moving to a computer-driven program, the direction of cursor movement on the screen can be controlled. However, a mechanical mouse must ride on a work surface (eg, a mouse pad) with a ball, and the ball must be exposed from the bottom of the mouse through a single hole, so that it can be used for a long time. , It becomes easier for dust to enter the inside of the mouse via the gap between the ball and the circular hole, affecting the operation of the mouse.

  The other conventional mouse is an optical mouse, which uses the abdominal illuminant (for example, LED) and a photosensor to sense the coordinates of the mouse, and has no problem of sucking dust. However, the optical mouse is limited in the materials used for the interface that reflects the light source, and absorbs light, penetrates light, or on reflective surfaces that interfere with light, such as metal paint, mirror surfaces and glass. On the surface or the like, the optical mouse cannot perform browsing and accurate click operations.

  In order to solve the above-mentioned drawbacks in using the optical mouse and further improve the resolution, a so-called laser optical mouse is used to generate a high-contrast figure using the coherence of the laser beam. This solves the problem of the reflective surface material and greatly improves the resolution sensitivity.

  The illuminant used for the illuminating action of the optical mouse meets the approved safety standards, but the user should still avoid looking directly with his eyes. It is necessary to avoid damaging the user by ensuring safety, especially in the direction of the laser emitter, by avoiding direct viewing. Conventional laser and optical mice do not close their light source sources with a shielding mechanism, and safety has been questioned when using laser or optical mice.

  Therefore, in order to remedy the above-mentioned drawbacks, the present inventor leads to the present invention which is particularly intensively researched and corresponds to the operation of science, has a reasonable design, and effectively improves the above-mentioned drawbacks.

  The object of the present invention is to provide an optical mouse having a shielding mechanism, and when the optical mouse leaves the work surface, the light beam is closed to avoid damage to the user, and further to the computer. Avoid arbitrary movement of the cursor on the screen.

  In order to achieve the above-mentioned object, the present invention is an optical mouse having a shielding mechanism operated on one work surface, and has one opening at the bottom or one inside thereof. One cabinet provided with two stoppers and two sliders, one circuit board provided in the cabinet, one optical switch electrically connected to the circuit board, and the circuit board and the electric circuit A sensor light source device that is connected to the optical switch and is activated or deactivated by turning on and off the optical switch, and is movably provided in the cabinet, and is formed by extending one protrusion downward. When the protruding part protrudes out of the opening or the slider and the stopper part correspond to each other and the cabinet leaves the work surface, the light Shields the optical path of the switch and a single shielding portion for cutting the light switch.

  The present invention prevents the light beam from damaging the user by closing the light beam when the optical mouse leaves the work surface, and further avoids any movement of the cursor on the computer screen.

  For a better understanding of the features and technical contents of the present invention, reference will now be made to the detailed description of the invention and the accompanying drawings, which, however, serve only for reference and description and further limit the invention. It is not meant to be.

  FIG. 1 is an exploded perspective view of an optical mouse according to the present invention. First, in the embodiments of the present invention, some elements of the mouse, such as push buttons, balls, push button switching, etc., are conventional techniques, and therefore the present invention will not be described further. At the same time, the mouse of the present invention is not limited to a wireless mouse or a cable type mouse, but in the drawings of the present invention, a cable type mouse is taken as an example.

  As shown with reference to FIGS. 1 to 3 again, the present invention provides an optical mouse having a shielding mechanism, which can be operated on one work surface 6, for example, a desk top or a mouse pad. The mouse includes one cabinet, one circuit board 2, one sensor light source device 3, one infrared controller 4, and one shielding unit 5.

  Among them, the outer shape of the cabinet 1 has an approximately arc shape, and can conform to the comfort of the user's operation by conforming to the ergonomic design. The cabinet 1 has a first outer side 11 and a second outer side 12 that correspond and join to each other. One opening 13 is provided at an appropriate location on the second outer side 12, and one opening 14 having a circular shape is provided at an appropriate location on the rear end. On both sides of the opening 14, sliders 15 each having a U-shape are provided so as to protrude upward.

  The outer shape of the circuit board 2 has an approximately arc shape, and one tear hole 21 and one through hole 22 are opened at appropriate positions. The circuit board 2 is installed between the first outer side 11 and the second outer side 12 of the cabinet 1 and can be screwed onto the second outer side 12 or the first outer side 11.

  The sensor light source device 3 has one light source generator and one optical detector (not shown), and the light source generator may be one laser emitter or one LED, and generates a light beam. Used to do. The optical detector is used to receive the light flux of the light source generator and performs a predetermined function. The sensor light source device 3 is installed on the circuit board 2 and is electrically connected to the circuit board 2 so that the sensor light source device 3 is activated or deactivated by turning on and off the infrared controller 4. Is also connected. The light source generator and the optical detector are located in the tear hole 21 and correspond to the opening 13 of the cabinet 1, so that the light beam can exert a necessary effect on the work surface 6.

  The infrared controller 4 is an optical switch that is installed on the circuit board 2, is electrically connected to the circuit board 2, and is electrically connected to the sensor light source device 3. The infrared controller 4 has one signal emitter 41 and one signal receiver 42. The signal emitter 41 and the signal receiver 42 are respectively located on both sides of the through hole 22 and correspond to the slider 15 and the opening 14 of the cabinet 1. The signal emitter 41 can emit one specific optical signal, and the signal receiver 42 receives and processes the optical signal, and the signal emitter 41 and the signal receiver 42 generate one switching signal. The sensor light source device 3 can be operated.

  The shielding part 5 is movably installed in the cabinet 1 and has an outer shape that is approximately rectangular and can be manufactured from plastic or metal. One light-transmitting portion 51 is provided at an appropriate position of the shielding portion 5, and one projecting portion 52 is formed with one end extending downward by one appropriate distance. In the drawings of the present invention, the translucent part 51 is a single through hole, but the translucent part 51 may be a single translucent lens (not shown), and the through hole or the lens is the same. The effect can be achieved. Both sides of the shielding unit 5 are slidably provided in the two sliders 15 and penetrate the through hole 22 of the circuit board 2 so that the translucent unit 51 and the signal emitter 41 and the It is located between the signal receiver 42 and at the same time, the protrusion 52 protrudes out of the opening 14 of the cabinet 1.

  The usage state of the operation of the present invention will be described in more detail with reference to FIGS. 4A, 4B, 5A, and 5B. Under the state of use, when the cabinet 1 is placed on the work surface 6, the protruding portion 52 comes into contact with the work surface 6, so that the shielding portion 5 rises, and the optical signal of the signal emitter 41 is transmitted from the shielding portion 5. By penetrating from the translucent part 51 to the signal receiver 42, an optical signal is received (for example, FIG. 4B), and the sensor light source device 3 generates a necessary effect. When the cabinet 1 leaves the work surface 6, the protrusion 52 does not contact the work surface 6. At this time, the shielding unit 5 slides by itself and moves downward (free fallen body) and descends, but the shielding unit 5 shields the optical signal of the signal emitter 41 by displacing the translucent unit 51 (for example, 5B), the signal receiver 42 cannot accept the optical signal from the signal emitter 41, and the signal receiver 42 finally transmits one closing signal, closes the signal, and closes the luminous flux of the sensor light source device 3. Used as follows.

  When the cabinet 1 comes into contact with the work surface 6 again, the projection 52 comes into contact with the work surface 6 so that the shielding unit 5 can generate a reset effect, and the optical signal of the signal emitter 41 penetrates to the signal receiver 42. The sensor light source device 3 can accept the opening signal, that is, generate the light beam and recover it.

  Furthermore, as shown with reference to FIGS. 4 and 5 again, one stopper portion 16 is provided in the first outer side 11 of the cabinet 1, and the stopper portion 16 is provided in the first outer side 11. It is fixed and corresponds to the shielding part 5 and has a gap of an appropriate distance between them. The stopper portion 16 is used to prevent the shielding portion 5 from dropping out of the slider 15 and losing its function when the cabinet 1 rotates to the relative side in use (for example, FIG. 6). In the drawings of the present invention, the stopper portion 16 is a single bump, but the stopper portion 16 can be replaced with a single elastic element (not shown), such as a compression spring or a stretching spring, and one end of the stopper portion 16 is the cabinet 1. The other end is connected to one end of the shielding part 5 to provide the same effect. Further, when the cabinet 1 leaves the work surface 6, the infrared light controller 4 is shielded by moving the shield 5 by the elasticity of the elastic element, and the sensor light source device 3 is closed.

  For example, as shown in FIG. 7, two stopper portions 16 can be provided in the cabinet 1. One of the stopper portions 16 is fixed in the top cover 11 and is extended by an appropriate length to be adjacent to the signal emitter 41 and the signal receiver 42. The other stopper portions 16 are fixed / slidably contacted in the two sliders 15, but the two stopper portions 16 correspond to each other, and the shielding portion 5 is located between the two stopper portions 16. Further, the shielding part 5 is not provided with the protruding part 52 and the translucent part 51. Under conditions of use, when the cabinet 1 is placed on the work surface 6, the optical signal of the signal emitter 41 is received by the gap between both the shielding part 5 and the stopper part 16 in the first outer side 11. By penetrating up to the unit 42, an optical signal is received. When the cabinet 1 is turned over from the use state, the shielding part 5 can slide downward to shield the light signal of the launch unit 41.

  However, as a result, the shielding portion 5 of the present invention also extends to an appropriate length of one step downward and is adjacent to the second outer side 12 of the cabinet 1, so that another stopper portion located below the shielding portion 5. Although 16 can be replaced, the same function as described above can be achieved.

  Therefore, the features and functions that can be generated by the present invention are summarized as follows.

  1. Due to the subtle structural design, the present invention can control and provide the opening or closing of the sensor light source device 3 by using the operation of the shield 5. Thereby, it is avoided that the light flux of the sensor light source device 3 causes damage to the user.

  2. The present invention can be provided so as to control the opening or closing of the optical transmission / reception device 3 by using the operation of the shielding unit 5, but when the cabinet 1 leaves the work surface 6, an arbitrary cursor on the computer screen can be used. Can be avoided.

  3. The present invention can achieve the required purpose by the shielding part 5 and the slider 15, but it is not necessary to add one more sensor circuit or the like, and the sensor light source device 3 can be turned on and off. Provide a reduction in manufacturing costs.
