In general, as shown in FIGS. 5 and 6, a conventional roller key having three types of operation directions (front / rear rotation operation, left / right swing operation and push operation) is insulated from the copper ring 41 (encoder / encoder, conductor). The roller sleeve 4 is annexed and is a hollow column body, and is supported by joining two plastic shafts 51 on a seat body 5 extending into a hollow portion in the center, and each terminal 42 is connected to a copper ring 41. Extending inward, electrically connected to the copper ring 41, fixed on the seat body 5, and by connection between the terminal 42 and the circuit board 6, the signal is transmitted to the circuit board via the copper ring (encoder), In addition, a cylinder protruding below the seat body 5 is installed, and one of the cylinders (which is relatively long in the center) is a support column 52, and the other three columns 53, 54, 55 are circuits. Thin film switches 61, 62, 6 on the plate 6 3 is used for driving.

As can be seen from FIG. 7, when using the roller key, a force is applied at the location indicated by the arrow (see FIG. 8). Move down in that direction, drive the switch on the upper left, further press the point indicated by the arrow, and if the amount of depression is 0.53mm, the switch in the lower center is also driven, so the conventional roller key is In use, if the user keeps pressing the same position, the other switches on the circuit board are driven, causing malfunction.

The main object of the present invention is to provide a roller structure module having a malfunction prevention mechanism that prevents a malfunction by preventing other switches on the circuit board from being driven by the user pressing the same position. Is to provide.

The roller structure module having the malfunction prevention mechanism of the present invention has a base to which the rotating structure is movably joined, and terminals that are respectively installed at both ends of the base and are electrically connected to the rotating structure. There are a first conducting portion and a second conducting portion at both ends on one side of the bottom portion of the base, respectively, and a support portion is installed between the first and second conducting portions, and the bottom portion corresponds to the support portion. A third conducting portion is installed on the opposite side of the side to be performed.

According to the present invention, it is possible to drive the switches at both ends of the roller structure module, and at the same time, it is possible to avoid driving the other central switch and prevent malfunction.

1 to 4 are one of many examples of the present invention. The present invention is a roller structure module having a malfunction prevention mechanism, which is an interface for communication between a user and an electronic system with an electronic device. The electronic device is, for example, a mobile communication network facility (not shown in the figure) such as a PDA, a mobile phone, or a Smart Phone, and this embodiment has a forward / backward rotation operation, a left / right swing operation, and a push operation. A roller structure module of various types of operating directions, including a base 1 to which the rotating structure 2 is movably joined, and terminals 21 that are respectively installed at both ends of the base 1 and are electrically connected to the rotating structure 2 The terminal 21 is electrically connected to a circuit contact provided in advance on the circuit board 3 of the electronic device, and the terminal 21 determines the back-and-forth rotation operation of the roller structure module. At both ends on one side of the bottom part, there are a first conducting part 11 and a second conducting part 12, respectively, and a support part 14 is installed between the first and second conducting parts 11 and 12, In addition, a third conducting portion 13 is installed on the bottom side opposite to the side corresponding to the support portion 14, and the first, second, and third conducting portions 11, 12, 13 are each provided with a roller structure. Installed on the thin film switches 31, 32, 33 previously installed on the circuit board 3 for controlling the horizontal swing operation or pushing operation of the module, and on the other one side of the base 1 bottom, A first malfunction prevention unit 15 and a second malfunction prevention unit 16 are installed in the vicinity of the positions of both ends of the third conduction unit 13, respectively, and the first and second malfunction prevention units 15, 16 are provided. Is installed on the opposite side of the side corresponding to the first and second conducting parts 11, 12, The first and second malfunction prevention portions 15 and 16 may be circular pillars or protrusions as necessary. Therefore, a roller structure module having a novel malfunction prevention mechanism is configured by the above structure.

According to the present embodiment, after being assembled as a whole, the terminal 21 of the base 1 is electrically connected to the contact of the pre-arranged circuit of the equipment, and the first, second and third conducting portions 11, 12 are connected. , 13 are installed corresponding to the thin film switches 31, 32, 33 preliminarily provided on the equipment. In the present invention, when the rotating structure 2 rotates, the terminal 21 detects the forward / backward rotation operation of the rotating structure 2, so that the thin film switches 31, 32, 33 is driven to perform a left / right swinging operation or a pushing operation. When the user uses the left / right swinging operation, the rotating structure 2 is pushed to the left or right, and the rotating structure 2 is moved to the left end or When pushed to the right end, the first and second conducting parts 11 and 12 move downward to drive the thin film switches 31 and 32, and further push the third conducting part 13 further down. Before the third conducting portion 13 moves and drives the thin film switch 33, the first or second malfunction prevention portions 15 and 16 are brought into contact with the circuit board 3 and act. The conduction part 13 is prevented from driving the thin film switch 33.

As shown in FIG. 4, by applying a force at the position indicated by the arrow, the roller structure module is inclined and is stopped when the first malfunction prevention unit 15 contacts the circuit board 3. At this time, a sufficient distance is maintained between the third conductive portion 13 and the corresponding thin film switch 33, so that the thin film switch 33 is driven by the third conductive portion 13 and the like. Can be prevented. In addition, it is possible to accurately drive the switches at both ends of the roller structure module, whether contact type or surface adhesive type, and whether the roller structure module has a frame. Driving the central switch can be avoided, and malfunction can be prevented.
