New Description: [New Technology Field] This creation is about a roller structure of an input device, especially a type that can greatly reduce the volume of the input device to maintain the portability and powerful functions of the product, and is sensitive at the same time. Comfortable, a roller structure that avoids improper handling. [Prior Art] There are many wheeled devices with rollers on the market, such as common mouse or remnant balls. Originally designed to be convenient for web browsers, the scroll wheel allows the user to intuitively touch the scroll wheel to continue the unfinished surface to avoid the inconvenience of traditional input device selection control. Then, focusing on the needs of the user, the roller device is gradually applied to various softwares, making it an important part of the modern input device. With the development of software, the way to increase the number of control keys on the input device has become the trend of the times, but because of the limitation of the finger activity space, the input device must add more functions in the limited space. Therefore, in addition to the original scrolling function, the scroll wheel gradually increases the pressing control function, which is the control mode of the existing scroll wheel. With the development of slavery era, the portability of input devices has become a page that users value. In order to facilitate carrying, the compactness of the input device has become a trend. In this way, the amount of space A available for use in the input break is reduced, so that many functions and materials cannot be effectively incorporated. Therefore, in the input devices on the market, those who emphasize the powerful functions are also relatively large in size; while the users who are convenient to carry are emphasized, their functions are greatly limited. Therefore, it is necessary to replace the existing input device with the existing input device, and reconfigure the structure of the existing input device with M298182, and reduce it as much as possible, so as to meet the design requirements of the wheeled device. The conventional roller design is shown in FIG. 1 and FIG. 2, and the eight-wheeled wheel includes a roller 11 in an encoder 12, and the encoder 12 is used for the rotation direction and the distance of the wheel 11 to output a specific signal to determine the firefly. On the 暮,, 4, then go to the cursor position on the curtain. The roller u is connected to the encoder 12 by an output. The shaft 13 is connected to the encoder 12 to make it bulky. In any case, the 'length' of the output shaft 13 is reduced, and the inter-work configuration is still greater than the width of the roller u and the encoder n. 3 and FIG. 4 show an old optical encoder roller structure, which has a structure of a roller 21 and an optical encoder 22, and is different from FIG. 2 and FIG. 2 in that the optical encoder 22 does not need to be connected to a roller. The vehicle is outputted, and the pattern of the surface of the optical sensing roller η is changed, thereby discriminating the active mode of the roller 21, thereby interpreting the movement of the roller 21. These optical inductions do not require an output shaft design, but are optically feasible. The optical encoder 22 still needs to be placed outside the roller 21, so that its volume is still large and cannot effectively reduce the volume of the input device. In addition, since the roller itself also has a pressing function, pressure sensing control is also a very important design step. FIG. 5 shows the design of the contact switch 14 on the old roller U of FIG. 1 and FIG. 2 . The contact switch 14 is placed at the lower end of the roller output shaft 13 . To avoid excessive volume, the conventional design places the contact switch 14 on the encoder 12 . The other end. Thus, when the input device performs the pressing operation, the encoder 12 is fixed as a fulcrum point. The roller π is a force application point, and the force point is on the contact switch 14. According to the principle of leverage, the design of such a force point in the middle is the most laborious, resulting in an inaccurate pressing operation, and the pressure must be increased frequently to increase the wear of the part. And the pressing direction of the pressing direction is curved with respect to the running direction, so that the 6 M298182 feeling during operation is less natural, and even the partial force is cut and the force is lost due to the lateral component force, so that it is necessary to Increase the force and increase hand fatigue. Further, as shown in FIG. 6, the contact switch design of the first coded scroll wheel of FIG. 2 and FIG. 4 is shown. Since it is not connected to the optical encoder 22 by hardware, the output of the wheel 21 can be on the 23-end. The guide track 25 is arranged such that the roller output shaft is called to operate in the guide-track 25, and the contact open switch % is designed at the other end of the output shaft 23. Compared with the design of Figure 5 and Figure 6, the method has no fixed fulcrum design, so that most of the force applied to the roller is transferred to the contact switch, so that the contact switch is easily damaged. At the same time, the guiding path 25 is too far away from the contact switch 24, and it is easy to generate a % bending moment, resulting in improper force application and damage to the parts. It can be seen that there are still many missing items in the above-mentioned household items, which is not a good designer and needs to be improved. In view of the shortcomings derived from the above-mentioned conventional roller structure, the creator of this case is eager to improve and innovate, and after years of painstaking research, he finally successfully developed the roller structure of the input device. [Technical content] The purpose of this creation is to provide a roller structure for an input device, which greatly reduces the overall volume of the roller structure, and also reduces the wheeling device, contributing to the development of a small portable and powerful input device. The second purpose of the present invention is to provide a roller structure for an input device which is smooth and easy to operate, and has a high-quality touch, which can effectively avoid errors caused by improper operation. M298182 Another purpose of this creation is to provide a roller structure for an input device, which is sensitive and correct, can prevent improper force application and repeated pressing action, and increase the output of the mouth to achieve the above-mentioned new purpose input. The roller structure of the device comprises a side wheel, a sliding bearing seat, an encoder, a circuit board, a contact switch and a roller bearing seat. The roller is disposed on one side of the roller, so that the sliding bearing seat is disposed in the groove of the roller, and an accommodating space is disposed inside the sliding bearing seat, and the encoder is fixed in the accommodating space. A positioning hole is disposed at an edge of the sliding bearing seat, and the wire end of the encoder is extended from the positioning hole, the circuit board is disposed under the roller, and a contact switch is disposed on the circuit board, and the contact opening relationship is The sliding t-bearing is pressed down to initiate the contact, and the t-roller bearing support & is placed at the bottom to support the aforementioned devices. The sliding bearing seat is externally provided with a guiding edge, and a guiding channel is disposed on the roller supporting seat, so that the guiding edge is placed in the guiding rail to limit the moving direction, and the outer side of the roller is provided with a rotating shaft, and the opposite a sliding plate is disposed on the sliding bearing seat, and the plate is provided with a shaft hole, so that the roller rotates in the shaft hole due to the rotating shaft, and the shaft hole has a channel reserved downward, and the hole The guiding edge is further convexly provided with a fulcrum which is positive for the contact switch and can activate the contact switch with a fulcrum when the sliding bearing seat is pressed down. [Embodiment] The contact switch 34, the circuit board 36, and a roller support base are shown in FIG. 7 to FIG. 11. The roller structure of the input device provided by the present invention mainly includes: - a roller 31 - an encoder 32.—Sliding bearing seats %, 37. M309182, the roller 31 is provided with a groove 311 on one side thereof, and the sliding bearing seat 33 is provided with a valley space 331 opposite to the groove side, so that the sliding bearing seat 33 is inserted into the groove 311 of the roller 31, and The inside of the roller 31 retains its accommodating space 331; the singer 2, 32 is fixed in the arranging space 331, and a positioning hole 332 is disposed at the edge of the sliding bearing seat 33, and the wire end of the encoder 32 can be The 321 extends from the positioning hole 332 to prevent the roller 31 from being obstructed by the wire 321; the circuit board 36 is disposed under the roller 31, and a contact switch 34 is disposed on the circuit board as described above. The cymbal is activated by the sliding bearing seat % pressing contact and the roller bearing seat 37 is placed at the bottom to support the aforementioned devices. The roller structure of the present seal is completed, because the encoder 33 has been placed in the accommodating space 331 of the sliding bearing seat 33, and the accommodating space 331 is again located in the groove 3^ of the roller. The position of the encoder 32 is inside the roller %, only the wire end 321 is exposed, so the overall width is only slightly larger than the width of the roller 31 itself, and the two old technologies have been greatly reduced in size. - a guiding edge is provided on the outside of the /month moving support 33. For example, a guide rail 35 is disposed on the roller and the two seats 37, so that the guiding edge 333 is placed on the guiding track, 35 The direction of the movement is restricted, and the outer side of the roller 31 is provided with a shaft 312, and a pair of plates 371 are disposed on the fifth wheel support seat 37. The positioning plate 371 is provided with a shaft hole 372. The roller 3 is rotated in the U-turn glaze 312 in the shaft hole 372, and the shaft hole 372 is reserved downward. In this way, in addition to the rotating work, the roller 31 can perform the pressing operation in a balanced manner. The Zeng, Green Office #2 hunting is used to linearly displace the roller 31 downward, so that the operation σ feels comfortable. . The guiding edge 333 M298182 is additionally provided with a point 334 which, for the contact switch 34, can activate the contact switch % with the fulcrum 334 when the sliding bearing seat 33 is lowered. Since the contact switch 34 is almost in the same position as the guide channel 35, the bending moment is not easily generated; and the position of the contact switch 34 and the guide channel 35 with respect to the point of application of the roller 31 is substantially the same, The force is relatively even, so that the parts are not easily damaged by improper force. In addition, the output shaft 313 is disposed in the groove 311 of the roller, and the output shaft is inserted into the encoder 32 to be rotated to achieve the encoder, and the calculation cloud for detecting the movement of the roller 31, Card cut old inch ^ and ask.
