Description

  The present invention relates to an electric / electronic device and an inspection system, and more particularly, to an electric / electronic device having an electrical connection using a flexible flat cable, an optical disc apparatus having an electrical connection using a flexible flat cable, and a computer for inspecting the optical disc device. It relates to a configured inspection system.

  Many wiring materials (electric wires) are used for electronic devices and home appliances, and in recent years, flexible flat cables having characteristics such as small size, high density, high performance, and light weight are often used (the following patent documents). 1-5).

JP 2008-84452 A JP 2009-104696 A JP 2005-85299 A Japanese Patent Laid-Open No. 11-6996 JP 2004-361735 A

  When mounting the above-described flexible flat cable, it is necessary to accurately insert and fix the end portion in a predetermined socket. This is because the end portion of the flexible flat cable is small and has a high density, and the end portion and the socket terminal do not come into contact with each other unless they are correctly inserted. If the device is used with the flexible flat cable obliquely inserted into the socket, the device or measurement board may be destroyed, electrical components may be deteriorated, or abnormal operation or display may occur. However, until now, there has been no known technique for detecting an oblique insertion of a flexible flat cable.

  The present invention has been made in view of the above problems, and detects an oblique insertion of a flexible flat cable in an electrical and electronic device having an electrical connection by a flexible flat cable, and prevents use in the oblique insertion state. It aims at providing the technique for.

  In order to solve the above-described problems, the present invention provides an electrical / electronic device having an electrical connection using a flexible flat cable, and includes a temperature detection unit that outputs temperature data corresponding to an ambient temperature, and at least a transmission line for the temperature data. A flexible flat cable in which both sides of the transmission line for the temperature data are a transmission line having a resistance component or a transmission line connected to the ground, and an instruction to start inspection of the mounting state of the flexible flat cable from the operator A receiving unit that accepts power, a power feeding unit capable of selectively feeding power to the temperature detecting unit, and a power feeding unit that selectively feeds the temperature detecting unit when the receiving unit receives the start instruction, Output based on the temperature data output from the temperature detector acquired via the flat cable It is constituted comprising a control unit to be performed on ahead, the.

  In the above configuration, the temperature detection unit detects the ambient temperature and outputs temperature data generated according to the ambient temperature. This temperature data is input to the control unit via the transmission line of the flexible flat cable. Here, the transmission line adjacent to the temperature data transmission line is a transmission line having a resistance component or a transmission line connected to the ground (a transmission line having a resistance component on both sides, a transmission line connected to the ground on both sides) , Including a case where one is a transmission line having a resistance component and the other is a transmission line connected to the ground). Therefore, when the flexible flat cable is obliquely inserted and short-circuited with at least one of the temperature data transmission line and the adjacent transmission lines, the temperature data input to the control unit becomes abnormal. Of course, not only the temperature data, but also an electric signal transmitted through another transmission line of the flexible flat cable becomes abnormal due to a short circuit.

  Therefore, the control unit controls the power supply unit to selectively supply power only to the temperature detection unit when the reception unit receives an instruction to start the inspection of the mounting state of the flexible flat cable from the operator. And the temperature data acquired via the flexible flat cable is acquired, and the output based on the said temperature data is performed with respect to a predetermined output destination. By checking the output performed in this way, the operator can determine whether the temperature data is abnormal, and in turn whether the flexible flat cable is short-circuited by diagonal insertion. It becomes possible to judge. Therefore, it becomes possible to detect the oblique insertion of the flexible flat cable and prevent the use of the flexible flat cable in the obliquely inserted state.

  As a selective aspect of the present invention, the temperature detector is a thermistor. The temperature detection unit described above can be realized by various means such as a thermocouple or a commercially available temperature measuring instrument, but can also be realized by a thermistor. When the temperature detection unit is realized by a thermistor, it is convenient if temperature data corresponding to the resistance value of the thermistor that changes according to a temperature change is input to the control unit via a flexible flat cable. That is, the voltage value generated in the thermistor according to the resistance value of the thermistor is input to the control unit via the flexible flat cable. Thus, by using the thermistor as the temperature detection unit, the present invention can be realized with a simple circuit configuration.

  As a selective aspect of the present invention, the predetermined output destination is a predetermined display unit, and the control unit executes display output based on the temperature data output from the temperature detection unit with respect to the predetermined display unit. It is as composition to do. That is, by performing the display based on the temperature data, the operator can visually recognize this display and grasp the temperature abnormality at a glance.

  As a selective aspect of the present invention, the predetermined output destination is an external device connected via a predetermined interface, and the control unit outputs data output based on the temperature data output from the temperature detection unit to the external device. It is configured to be executed on the device. In other words, by executing data output based on temperature data to an external device, it is possible to leave a log relating to temperature on the external device for use in various statistical processing, or to convert the output data into a more readable form for display. -It can be used for output such as printing.

  As a selective aspect of the present invention, the control unit determines whether the flexible flat cable is attached based on the temperature data, and outputs the presence / absence of the oblique insertion of the flexible flat cable to the predetermined output destination. As a configuration. That is, it does not output the temperature data itself, but outputs whether the flexible flat cable is correctly attached or inserted obliquely. Therefore, the operator can grasp the mounting state of the flexible flat cable clearly at a glance.

  As an optional aspect of the present invention, the electric / electronic device is an optical disk device including an optical pickup and a control board on which a control circuit for the optical pickup is formed, and the temperature detection unit is included in the optical pickup. A thermistor that outputs temperature data according to the ambient temperature of the laser diode, the control unit is configured by the control circuit, the flexible flat cable connects the optical pickup and the control board, and the control An interface that can be connected to an external device is mounted on the board, and the control unit outputs an output based on the temperature data output from the temperature detection unit acquired via the flexible flat cable to the external device connected to the interface. It is configured to execute on the other hand. According to this configuration, it is possible to detect an oblique insertion of the flexible flat cable in the optical disc apparatus and prevent use in the oblique insertion state.

  As another aspect of the present invention, in an inspection system including an optical disk device having electrical connection using a flexible flat cable and a computer for inspecting the optical disk device, the optical disk device is included in an optical pickup. A thermistor that outputs temperature data corresponding to the ambient temperature of the laser diode, a control board on which the control circuit of the optical pickup is formed, a flexible flat cable that connects the optical pickup and the control board, and the control board An interface mounted on the computer and connectable to the thermistor, and a power supply unit capable of selectively supplying power to the thermistor. The flexible flat cable includes at least a transmission line for the temperature data. Next to the transmission line A transmission line having a resistance component or a transmission line connected to the ground, and the computer includes a reception unit that receives an instruction to start various inspections including an inspection of the mounting state of the flexible flat cable from an operator, A display unit that performs display, and when the reception unit receives an instruction to start the inspection, the computer performs selective power supply to the thermistor by controlling the control circuit through the interface. The control circuit acquires the temperature data output from the temperature detection unit through the power supply via the flexible flat cable, and outputs the acquired temperature data to the computer connected to the interface. Whether the temperature data is within the specified temperature range Performed Kano displayed on the display unit, when located outside the predetermined temperature range is configured so as to stop subsequent inspection. Thus, even when configured as a system, the same operational effects as the above-described configurations can be obtained.

As described above, according to the first aspect of the present invention, it is possible to provide an electrical and electronic device capable of detecting the oblique insertion of the flexible flat cable and preventing the use in the obliquely inserted state.

Hereinafter, embodiments of the present invention will be described in the following order.
(1) Configuration of optical disc apparatus:
(2) Inspection work:
(3) Summary and modifications:

(1) Configuration of optical disc apparatus:
FIG. 1 is a block diagram showing a configuration of an optical disc apparatus 100 according to an embodiment of the present invention. In the present embodiment, the optical disc apparatus 100 constitutes an electric / electronic device. The optical disk device 100 includes an optical pickup device 10 and a control board P, and the optical pickup device 10 and the control board P are connected by a flexible flat cable FFC. The optical pickup device 10 includes a semiconductor laser device such as a laser diode that irradiates an optical recording medium with a light beam, and a light receiving unit such as a photodiode that detects the amount of light emitted from the semiconductor laser device.

  A control circuit of the optical pickup device 10 is formed on the control board P, and this control circuit constitutes the optical pickup control unit 20. A power supply voltage is supplied to the control board P from the power supply circuit 30, and a power supply voltage is supplied to the optical pickup device 10 from the power supply circuit 30 via the control board P and the flexible flat cable FFC.

  The optical pickup device 10 includes a thermistor 11 (temperature detection unit) in the vicinity of a temperature-dependent element such as a laser diode or a photodiode. On the other hand, a resistor R1 is mounted on the control board P. More specifically, the terminal A of the thermistor 11 is connected to the ground, the terminal B of the thermistor 11 is connected to the terminal C of the resistor R1 via the flexible flat cable FFC, and the terminal D of the resistor R1 is connected to the power supply circuit 30. It is connected to a 3.3V (constant voltage) power supply line.

  That is, the thermistor 11 and the resistor R1 constitute a split resistor. Since the resistance value of the thermistor 11 changes according to the ambient temperature, the voltage value at the dividing point of the dividing resistor constituted by the resistor R1 and the thermistor 11 becomes a value corresponding to the resistance value of the thermistor 11. The optical pickup control unit 20 acquires the voltage value at this division point and uses it as temperature data.

  The thermistor 11 and the resistor R1 are electrically connected via the transmission line of the flexible flat cable FFC. Therefore, when the flexible flat cable FFC is obliquely inserted, the voltage value of the dividing point on the control board P side becomes an abnormal value that cannot be normally obtained. Therefore, it can be determined whether or not the flexible flat cable FFC is obliquely inserted based on whether or not the voltage value at the dividing point is within a normal range. In addition, the diagonal insertion here means the state which the terminal of flexible flat cable FFC is contacting with terminals (for example, adjacent terminals) other than the terminal which should contact originally when inserted in a socket.

  FIG. 2 is an explanatory diagram of a mounting state of the flexible flat cable. In this embodiment, a socket is provided on at least one of the control board P and the optical pickup device 10, and at least one terminal of the flexible flat cable FFC is inserted and fixed in the socket. At this time, if the connection terminal of the socket and the film peeling portion at the tip of the flexible flat cable FFC are in a one-to-one contact with the correct correspondence, a control signal and an output signal are appropriately transmitted between the control board P and the optical pickup device 10. The power supply voltage can be transmitted.

  However, as shown in FIG. 2, when the flexible flat cable FFC is attached obliquely (hereinafter referred to as “oblique insertion”), the ends of the transmission lines constituting the flexible flat cable FFC are connected to a plurality of connection terminals of the socket. Due to the contact, a short circuit occurs between adjacent transmission lines. When a short circuit occurs, it may cause deterioration or destruction of electrical and electronic parts of the optical disc apparatus 100, or the optical disc apparatus 100 may operate abnormally or output abnormal data. Here, a circuit state when a short circuit occurs with an adjacent transmission line will be described with reference to FIG.

  FIG. 3 is a diagram showing an equivalent circuit of a circuit that outputs temperature data corresponding to each mounting state of the flexible flat cable. FIG. 3A is an equivalent circuit when the flexible flat cable FFC is correctly attached to the connector. In the circuit shown in the figure, the thermistor 11 and the resistor R1 appropriately constitute a divided resistor.

  FIG. 3B is an equivalent circuit in the case where the transmission line for temperature data is short-circuited by the transmission line having the resistance component due to the slanting of the flexible flat cable FFC. In the case of FIG. 3B, this is equivalent to a circuit in which the resistance component of the adjacent transmission line is arranged in parallel with the resistance component by the thermistor 11. That is, a voltage similar to that when the resistance of the thermistor 11 rises is generated at the dividing point. Whether the voltage indicates a temperature increase or a temperature decrease differs depending on whether the thermistor 11 is an NTC (negative temperature coefficient) or a PTC (positive temperature coefficient). In any case, the optical pickup control unit 20 receives temperature data indicating a temperature exceeding the upper limit or lower limit of the variation range of the resistance value of the thermistor 11.

  FIG. 3C is an equivalent circuit when the temperature data transmission line is short-circuited to the transmission line connected to the ground line by slanting the flexible flat cable FFC. In the case of FIG. 3C, this is equivalent to a circuit shorted to the ground in parallel with the resistance component by the thermistor 11. That is, a ground potential is generated at the dividing point. Also in this case, the optical pickup control unit 20 receives temperature data indicating a temperature exceeding the upper limit or lower limit of the variation range of the resistance value of the thermistor 11.

  As described above, when the flexible flat cable FFC has a resistance line or a transmission line connected to the ground next to the temperature data transmission line, when the flexible flat cable FFC is obliquely inserted, It can be seen that abnormal temperature data is input to the optical pickup controller 20.

  In order to utilize such characteristics, either a transmission line having a resistance component or a transmission line connected to the ground is arranged on both sides of the temperature data transmission line of the flexible flat cable FFC. Therefore, in the present embodiment, the computer 200 to which the temperature data is input from the optical pickup control unit 20 distinguishes between the abnormal temperature data and the normal temperature data, thereby confirming whether the flexible flat cable is correctly attached. It is possible to determine whether it has been inserted. Further, the temperature data output from the thermistor 11 can be output to the computer 200 as described later, or output to the display unit of the optical disk device, so that the operator can grasp the mounting state of the flexible flat cable. .

  In addition to the configuration described above, the optical disc apparatus has the following configuration. First, on the control board P, the switch circuit 22 capable of switching the above-described 3.3 V on / off with respect to the terminal D of the resistor R1 is formed. The control board P is also formed with a switch circuit (not shown) that can switch on and off the supply of the power supply voltage to each part of the optical disc apparatus 100. The optical pickup control unit 20 can selectively supply the above-described 3.3 V to the terminal D of the resistor R1 by selectively switching the switch circuit 22. That is, the optical pickup control unit 20 can cause the thermistor 11 to output temperature data without operating each unit other than the thermistor 11.

  In addition, the control board P includes an interface 24 that can be connected to a personal computer or the like, which is an external device, via a connection cable. The computer 200 also includes a similar interface 210, and in this embodiment, the interface 24 and the interface 210 are connected. The computer 200 can communicate with the optical pickup control unit 20 via these interfaces. The computer 200 further includes an operation unit 220 for receiving an operation input from the operator and a display 230 for displaying various information. The operator performs a predetermined operation input via the operation unit 220. Thus, the optical pickup control unit 20 can be controlled, and further, the entire optical disc apparatus 100 can be controlled. In addition, the computer 200 displays various information related to communication on the display 230, so that the operator can present the information acquired through communication so that the user can visually recognize the information. That is, in this embodiment, the optical pickup control unit 20 and the computer 200 constitute a control unit.

  In addition, the optical disk device 100 includes, as a configuration of the optical pickup device 10, a spindle motor that rotationally drives the optical recording medium, a slide motor that slides the optical pickup device along the recording surface of the optical recording medium, A drive system Drv such as a focus coil and a tracking coil for adjusting tracking is provided, and these drive drivers are provided. This drive driver drives each motor according to the control of the optical pickup control unit 20.

(2) Inspection work:
FIG. 4 is a flowchart showing a flow of the oblique insertion inspection work of the flexible flat cable. The inspection work according to the present embodiment is executed in an inspection system including the optical disc device 100 and the computer 200 described above.

  In addition, the oblique insertion inspection work of the optical disc apparatus 100 according to the present embodiment is performed at the beginning of a drive system adjustment / evaluation work sequence performed after product assembly. In general, in the production line of electrical and electronic equipment, adjustment / evaluation work is performed to test energization / communication / control on each part before, during, or during product assembly. By performing the oblique insertion inspection work at the beginning of this work, the mounting state of the flexible flat cable FFC can be corrected before each part of the optical disc apparatus 100 is actually operated in the adjustment / evaluation work. Of course, the oblique insertion inspection work may be performed independently, as part of other work, or in product repair work.

  In the oblique insertion inspection work shown in FIG. 4, first, an operator attaches a flexible flat cable to a predetermined socket (S100). Then, the worker connects the AC inlet of the power circuit 30 to the power connector, and connects the optical disc device 100 and the computer 200 with a connection cable. As a result, the optical pickup control unit 20 of the optical disc apparatus 100 becomes operable, and the optical disc apparatus 100 becomes operable according to the control of the computer 200 via the interface 24.

  Next, the worker performs a predetermined operation on the operation unit of the computer 200 to start the inspection program (S110). This inspection program is a program for adjusting / evaluating the optical disc apparatus 100, and after confirming normal installation of the flexible flat cable FFC by the oblique insertion inspection, adjustment and evaluation of the optical disc apparatus 100 are executed. Yes. In the present embodiment, the operation unit 220 of the computer 200 that receives a predetermined scan constitutes a reception unit.

  When the computer 200 accepts the predetermined operation and starts the inspection program (S200), the computer 200 communicates with the optical pickup control unit 20 to instruct start of power supply to the thermistor 11 (S210). When this instruction is input, the optical pickup control unit 20 starts supplying constant voltage to the thermistor 11 by switching the switch circuit 22 (S300). Then, 3.3 V is applied to the resistor R1, a voltage is applied to the divided resistor formed by the thermistor 11 and the resistor R1, and a voltage is generated at the dividing point of the divided resistor. That is, the output of temperature data is started. The switch circuit 22 and the power supply circuit 30 as a power supply source constitute a power supply unit in the present embodiment.

  Next, the computer 200 instructs the optical pickup control unit 20 to output the temperature data to the computer 200 (S220). Then, the optical pickup control unit 20 acquires temperature data (S310) and outputs the data to the computer 200 (S320). As described above, in this embodiment, the computer 200 is an output destination of temperature data.

  The computer 200 determines whether or not the temperature is within a normal fluctuation range based on the temperature data output from the optical pickup control unit 20 (S230). If it is determined that the temperature data is within the normal fluctuation range, the computer 200 determines that the flexible flat cable FFC is not obliquely inserted (S230: Yes), and performs subsequent evaluation and adjustment on the optical disc device 100. On the other hand, if it is determined that the temperature data is outside the normal fluctuation range, the computer 200 determines that the flexible flat cable FFC is obliquely inserted (S230: No).

  Note that the above-described fluctuation range can be represented by an upper threshold that indicates an upper limit of normal temperature fluctuation and a lower threshold that indicates a lower limit of normal temperature fluctuation. The computer 200 includes a storage medium that stores these upper threshold value and lower threshold value. These lower threshold value and upper threshold value indicate a range in which the temperature of the optical pickup device 10 can fluctuate at a normal room temperature. For example, the lower threshold value corresponds to 10 ° C., and the upper threshold value is set to 45 ° C. It can be made to correspond.

  When the oblique insertion of the flexible flat cable FFC is detected, the computer 200 displays the fact on the display 230 (S240), and ends the inspection program. The operator confirms the display 230 of the computer 200 as appropriate after starting the inspection program, and can recognize that the flexible flat cable FFC is obliquely inserted when the display 230 shows that effect. Thus, in this embodiment, since the presence or absence of the diagonal insertion of the flexible flat cable FFC is displayed, the operator can easily determine the presence or absence of the diagonal insertion.

  When the oblique insertion is recognized, the operator turns off the power of the optical disc apparatus 100, confirms the mounting state of the flexible flat cable FFC, and remounts the flexible flat cable FFC. Then, by performing the work after step S100 again, the computer 200 starts the inspection program, and until the flexible flat cable FFC is confirmed to be normally attached, the flexible flat cable attachment state is corrected and the inspection work is performed. Run repeatedly. Therefore, before the adjustment / evaluation work for energizing and operating the entire optical disc apparatus 100 is performed, the mounting state of the flexible flat cable FFC is surely normal. As a result, it is possible to prevent the deterioration and destruction of the optical disk apparatus 100, abnormal operation, abnormal display, and the like.

(3) Summary and modifications:
In the embodiment described above, the thermistor 11 that outputs temperature data corresponding to the ambient temperature and at least the temperature data transmission line are provided, and both adjacent to the temperature data transmission line are connected to a transmission line or a ground having a resistance component. When the operator receives a flexible flat cable FFC that is a connected transmission line and an instruction to start inspection of the mounting state of the flexible flat cable FFC from an operator, the switch circuit 22 is controlled to start selective power feeding to the thermistor 11. The optical disc apparatus 100 includes an optical pickup control unit 20 that acquires the temperature data output from the thermistor 11 by the power supply via the flexible flat cable FFC, and outputs the acquired temperature data to the computer 200 via the interface 24. I am letting. Therefore, it becomes possible to detect the oblique insertion of the flexible flat cable and prevent the use of the flexible flat cable in the obliquely inserted state.

  In the above-described embodiment, the case where a thermistor is used as the temperature detection unit has been described as an example. However, a thermometer that outputs temperature data measured using a thermocouple via the flexible flat cable FFC, Etc. may be used. As long as the optical pickup control unit 20 acquires temperature data via the flexible flat cable FFC, the temperature acquired by the optical pickup control unit 20 when the flexible flat cable FFC is obliquely inserted in any temperature detection unit. This is because the data shows an abnormal value. That is, if it is determined whether or not the temperature data is within a normal temperature fluctuation range, the same operational effects as when the thermistor is used are obtained.

  In the above-described embodiment, the example in which the external computer 200 controls the optical disc apparatus 100 to execute the inspection work has been described. However, the optical pickup control unit 20 in the optical disc apparatus 100 executes the above-described inspection program. It may be. In this case, a predetermined operation performed by the operator on the operation unit of the computer 200 is performed on the operation unit of the optical disc apparatus 100, and the temperature data is displayed and output on a display unit included in the electric / electronic device. Therefore, the operator appropriately checks the display unit included in the optical disc apparatus 100. Of course, communication between the computer 200 and the optical disc apparatus 100 does not occur. In this modification, the optical pickup control unit 20 constitutes a control unit.
