  The support portion 25 has a function of supporting the base portion 21 via the connecting portions 261, 262, 263, and 264. The support portion 25 is disposed on the −y axis direction side with respect to the base portion 21 and has a long shape 251 extending along the x axis direction, and from both ends of the portion 251 along the + y axis direction. Two portions 252 and 253 extending.

Thereby, the softness | flexibility in the various directions of the connection parts 261,262,263,264 can be improved. Therefore, the shock resistance of the sensor element 7X is increased, and the detection characteristics are improved by keeping the frequency of unnecessary vibration of the base portion 21 accompanied by bending deformation of the connecting portions 261, 262, 263, and 264 away from the frequency of driving vibration and detection vibration. Can be. Further, the sensor element 7X can be reduced in size.

-Electrode-
The electrodes provided on the surface of the piezoelectric substrate 2 described above have a drive signal electrode, a drive ground electrode, a detection signal electrode, and a detection ground electrode, although not shown. Such an electrode is not particularly limited as long as it has electrical conductivity. For example, Ni (nickel), Au (gold), Ag ( It can be composed of a metal film obtained by laminating films such as silver) and Cu (copper).

  In the sensor element 7X configured as described above, when an electric field is generated between the drive signal electrode and the drive ground electrode in a state where no angular velocity is applied to the sensor element 7X, the drive vibrating arms 221 and 222 are As shown by the middle arrow A, bending vibration (drive vibration) is performed so as to be opposite to each other in the x-axis direction.

  Further, along with this drive vibration, the adjustment vibration arms 241 and 242 also perform bending vibration (adjustment vibration) so as to be opposite to each other in the x-axis direction.

  When an angular velocity ω around the central axis a1 along the y-axis direction is applied to the sensor element 7X in a state where this driving vibration is performed, Coriolis force acts on the driving vibration arms 221 and 222, and driving is performed by this Coriolis force. The vibrating arms 221 and 222 bend and vibrate so as to be opposite to each other in the z-axis direction. Accordingly, the detection vibrating arms 231 and 232 vibrate (detection vibration) so as to be opposite to each other in the z-axis direction as indicated by B in FIG. Due to this detection vibration, charges generated in the detection vibration arms 231 and 232 are taken out from the detection signal electrode as a detection signal, and the angular velocity is obtained based on this detection signal.

  At this time, similarly to the drive vibration arms 221 and 222, the adjustment vibration arms 241 and 242 also bend and vibrate so as to be opposite to each other in the z-axis direction, but no charge is output due to this bending vibration. That is, regardless of the presence or absence of the action of the Coriolis force, the charges output from the adjustment vibration arms 241 and 242 are basically only due to the adjustment vibration described above and are constant. Thereby, the leak output resulting from the manufacturing variation of the piezoelectric substrate 2, etc. can be adjusted.

The sensor element 7X as described above is installed such that the central axis a1 is parallel to the X axis shown in FIGS. Thereby, the angular velocity ω _X around the X axis can be detected by the sensor element 7X. The sensor element 7Y is installed so that the central axis a1 is parallel to the Y axis shown in FIGS.

Further, the support beam 452 passes between the drive vibration arm 423 and the detection vibration arm 431 and connects the main body portion 411 and the fixing portion 441 of the base portion 41. Similarly, the support beam 453 passes between the drive vibration arm 422 and the detection vibration arm 432 and connects the main body portion 411 and the fixed portion 442 of the base portion 41. Further, the support beam 454 passes between the driving vibration arm 424 and the detection vibration arm 432 and connects the main body portion 411 and the fixing portion 442 of the base portion 41.

  Each of the support beams 451 to 454 has a long shape, and has a plurality of bent or curved portions in the middle thereof.

-Electrode-
The electrodes provided on the surface of the piezoelectric substrate 4 described above have a drive signal electrode, a drive ground electrode, a detection signal electrode, and a detection ground electrode, although not shown.

  In the sensor element 7Z configured as described above, when an electric field is generated between the drive signal electrode and the drive ground electrode in a state where the angular velocity is not applied to the sensor element 7Z, each of the drive vibrating arms 421 to 424 is shown in FIG. Bending vibration (drive vibration) is performed in the direction indicated by the middle arrow C. At this time, since the drive vibration arms 421 and 422 and the drive vibration arms 423 and 424 are vibrating symmetrically in FIG. 4, the base 41 and the detection vibration arms 431 and 432 hardly vibrate.

  When the angular velocity ω around the central axis a2 (center of gravity) along the z-axis is applied to the sensor element 7Z in the state where the driving vibration is performed, the detection vibration (vibration in the detection mode) is excited. Specifically, the Coriolis force in the direction indicated by the arrow D in FIG. 4 acts on the drive vibrating arms 421 to 424 and the connecting arms 412 and 413 of the base 41 to excite new vibrations. Accordingly, detection vibrations in the direction indicated by arrow E in FIG. 4 are excited in the detection vibration arms 431 and 432 so as to cancel the vibrations of the connecting arms 412 and 413. Then, the charges generated in the detection vibrating arms 431 and 432 by this detection vibration are taken out from the detection signal electrodes as detection signals, and the angular velocity is obtained based on the detection signals.

The sensor element 7Z as described above is installed such that the central axis a2 is parallel to the Z axis shown in FIGS. Thereby, the angular velocity ω _Z around the Z axis can be detected by the sensor element 7Z.

  5 is a back view showing the terminal arrangement of the electronic device shown in FIG. 1, and FIG. 6 is a diagram for explaining the operation of the electronic device shown in FIG.

  The plurality of terminals 642 provided on the bottom surface (mounting surface) of the base 61 include two power supply terminals 642a1 and 642a2, four external capacitor terminals 642b1 to 642b4, a plurality of other terminals 642c1 to 642c10, and four terminals 642d1. -642d4.

  The power supply terminals 642a1 and 642a2 are connected to the terminals 31a1 and 31a2 of the measuring apparatus 30 and are terminals to which a power supply voltage from an external power supply is input. For example, the power supply terminal 642a1 is an interface circuit included in the IC chip 8. Is a terminal (VDDI) to which a power supply voltage for driving is input, and the power supply terminal 642a2 is a terminal (VDD) to which a power supply voltage used for the operation of the entire IC chip 8 is input.

  The external capacitance terminals 642b1 to 642b4 are connected to the terminals 31b1 to 31b4 of the measuring device 30 and are connected to capacitors for stabilizing the power supply voltage inside the IC chip 8, respectively. For example, the external capacitance terminals 642b1 is a terminal (VDDL) to which a capacitor for stabilizing the power supply voltage of the interface circuit included in the IC chip 8 is connected, and the external capacitance terminal 642b2 is a power supply voltage of the drive circuit that drives the sensor element 7X. The external capacitor terminal 642b3 is a terminal to which a capacitor for stabilizing the power supply voltage of the drive circuit that drives the sensor element 7Z is connected (VDDMX). VDDMZ), and the external capacitor terminal 642b4 is a drive circuit for driving the sensor element 7Y. Source is a terminal to which the capacitor for stabilizing the voltage is connected (VDDMY).

  The terminal 642c10 is a signal output terminal (MISO) that is connected to the terminal 31c10 of the measuring device 30 and outputs a signal from an interface circuit included in the IC chip 8 to the outside. As a communication method using the terminal 642c10, for example, SPI (registered trademark) (Serial Peripheral Interface) is used. The other terminals 642c1 to 642c9 are connected to the terminals 31c1 to 31c9 of the measuring apparatus 30. For example, the terminal 642c9 is a signal input terminal (MOSI) that inputs a signal to an interface circuit included in the IC chip 8, and the terminal 642c6 , 642c7 are terminals (I2C_DA, I2C_CL) used when I2C (registered trademark) is selected as the communication system, and the terminal 642c1 is a terminal (SS) to which a signal for selecting the communication system is input, and the terminal 642c1 By using, the communication method can be selected between SPI and I2C.

  The terminal 642c2 is a terminal (DRY) used to measure the timing of data update in the IC chip 8, for example. The terminals 642c3 and 642c4 are, for example, electrically opened terminals (NC), respectively. The terminal 642c8 is, for example, a terminal (SCLK) to which a clock signal is input. The terminal 642c5 is a terminal (GND) connected to the reference potential. Terminals 642d1 to 642d4 are terminals (VPP) to which a power supply voltage used when setting information is written in the IC chip 8 is input.

  The terminals having the functions as described above are arranged side by side along the outer periphery of the bottom surface of the base 61.

  More specifically, as shown in FIG. 5, the base 61 of the package 6 has a first side 60a and a second side 60b, and a first side 60a and a second side 60b that face each other in plan view. It has a rectangular outer shape including a third side 60c and a fourth side 60d that extend in the intersecting direction and face each other. In the present embodiment, the first side 60a and the second side 60b are parallel to each other, and the third side 60c and the fourth side 60d are orthogonal to the first side 60a and the second side 60b.

  A terminal 642c1, a power supply terminal 642a1, a terminal 642c2, and an external capacitance terminal 642b1 are arranged in this order along the first side 60a. Further, the external capacitor terminal 642b2, the terminal 642c3, the power supply terminal 642a2, and the terminal 642c4 are arranged in this order along the second side 60b. Further, the terminal 642c5, the terminal 642c6, the terminal 642c7, and the external capacitor terminal 642b3 are arranged in this order along the third side 60c. Further, the external capacitor terminal 642b4, the terminal 642c8, the terminal 642c9, and the terminal 642c10 are arranged in this order along the fourth side 60d.

  Here, the power terminal 642a1 is arranged on the first side 60a side of the base 61, and the power terminal 642a2 is arranged on the second side 60b side from the center C of the base 61. The terminal 642c10 that is a signal output terminal is arranged on the fourth side 60d side from the center C of the base 61.

  In particular, the power supply terminal 642a1 and the terminal 642c10 are disposed so as to avoid positions that are 90 ° rotationally symmetric, 180 ° rotationally symmetric, and 270 ° rotationally symmetric with respect to the center C of the base 61 (mounting surface). In other words, avoid the positions that are 90 degree rotationally symmetric, 180 degree rotationally symmetric, and 270 degree rotationally symmetric with respect to the center of the power supply terminal 642a1 and the base 61 (mounting surface). 642c10 is arranged. That is, as shown in FIG. 6, when the base 61 is erroneously attached to the measuring apparatus 30 with the base 61 rotated about its center C at any angle of 90 °, 180 °, and 270 °, the terminal 642c10 is viewed in plan view. Thus, the terminals 31a1 and 31a2 to be connected to the power supply terminals 642a1 and 642a2 are arranged so as not to overlap.

  According to such an electronic device 1, even if it is erroneously attached to the measuring apparatus 30 (inspection apparatus) in an orientation (angle) different from the normal orientation (angle), the signal output terminal 642c10 is attached. Input of the power supply voltage can be prevented, and as a result, adverse effects on the electronic device 1 can be reduced.

  Further, even when the electronic device 1 is mistakenly mounted on the mounting substrate in an orientation (angle) different from the normal orientation (angle), the power supply voltage is prevented from being input to the signal output terminal 642c10. As a result, adverse effects on the electronic device 1 can be reduced. As described above, when the electronic device 1 is erroneously mounted on the mounting board, the function of the connection terminal on which the electronic device 1 is mounted on the mounting board can be switched to a correct function according to the direction of the electronic device 1. That is, the function of the connection terminal on the mounting board side can be switched in accordance with the arrangement of the mounting terminals of the electronic device 1 mounted in the wrong direction (angle). This switching method is effective when it is difficult to remove the electronic device 1 from the mounting board.

  In the present embodiment, the case where the mounting surface is substantially rectangular and has a four-fold symmetric outer shape is described as an example. However, the present invention is not limited to this, and the outer shape of the mounting surface is n-fold symmetric (however, n is an integer of 2 or more), when θ is an angle obtained by dividing 360 ° by n and m is an integer of 1 or more and smaller than n, the power supply terminal and the signal output terminal are It is only necessary to avoid the position (m × θ °) that is rotationally symmetric with respect to the center of the mounting surface.

  The power supply terminals 642a1 and 642a2 (first and second power supply terminals) are arranged at positions that are 180 degrees rotationally symmetric with respect to the center C of the base 61 (mounting surface). That is, as shown in FIG. 6 (a), when the base 61 is erroneously attached to the measuring apparatus 30 and is mounted on the mounting substrate in a state where the base 61 is rotated about its center C, the power supply terminal 642a1 is seen in plan view. The power supply terminal 642a2 is arranged so as to overlap the terminal 31a2 to be connected, and the power supply terminal 642a2 is arranged to overlap the terminal 31a1 to be connected to the power supply terminal 642a1. As a result, even if the measurement device 30 (inspection device) or the mounting substrate is erroneously mounted (mounted) in a direction (angle) rotated 180 degrees from the normal direction, the power supply voltage is input to the power supply terminals 642a1 and 642a2. Thus, it is possible to prevent the power supply voltage from being input to the terminal 642c10 which is a signal output terminal.

  A terminal 642c10 that is a signal output terminal is a terminal that outputs a digital signal from a digital communication circuit included in the IC chip 8, or a terminal that outputs an analog signal from an analog communication circuit included in the IC chip 8. . Therefore, even if the measurement device 30 (inspection device) or the mounting board is mounted (mounted) in the wrong direction (angle), the power supply voltage is prevented from being input to the digital communication circuit or the analog communication circuit. Can do.

  The external capacitor terminals 642b1 to 642b4 are electrically connected to a regulator circuit included in the IC chip 8. The power supply terminals 642a1 and 642a2 and the external capacitor terminals 642b1 to 642b4 are positioned at any one of 90 degree rotational symmetry, 180 degree rotational symmetry, and 270 degree rotational symmetry with respect to the center C of the base 61 (mounting surface). Arranged to avoid. In other words, with respect to the power terminals 642a1 and 642a2 and the center C of the base 61 (mounting surface), a position that is 90 degree rotationally symmetric, a position that is 180 degree rotationally symmetric, and a position that is 270 degree rotationally symmetric. The external capacitance terminals 642b1 to 642b4 are arranged so as to avoid at least one of. This prevents the power supply voltage from being input to the regulator circuit via the external capacitance terminals 642b1 to 642b4 even if the measurement apparatus 30 (inspection apparatus) is mounted (mounted) in the wrong direction (angle). As a result, adverse effects on the electronic device 1 can be reduced.

  In addition, the external capacitor terminals 642b1 to 642b4 are electrically connected to different regulator circuits included in the IC chip 8, and are mutually symmetrical with respect to the center C of the base 61 (mounting surface) by 90 degrees and rotated by 180 degrees. It is disposed on the mounting surface at a position that is either symmetric or 270-degree rotationally symmetric. In other words, any one of the external capacitor terminals 642b1 to 642b4 and a position that is 90 ° rotationally symmetric, 180 ° rotationally symmetric, and 270 ° rotationally symmetric with respect to the center C of the base 61 (mounting surface). The other one of the external capacitance terminals 642b1 to 642b4 is disposed at at least one of the positions. As a result, even if the measurement device 30 (inspection device) is erroneously mounted (mounted) in a direction (angle) different from the normal direction (angle), the power supply voltage is a terminal other than the external capacitance terminals 642b1 to 642b4. Therefore, it is possible to prevent the power supply voltage from being input to the external capacitor terminals 642b1 to 642b4. In addition, when wrongly mounted, the same type of circuit is connected to the external capacitor terminals 642b1 to 642b4, and compared with the case where a different type of circuit is connected to the external capacitor terminals 642b1 to 642b4, an electronic device due to incorrect mounting. 1 can be effectively reduced. Here, an arbitrary one of the external capacitance terminals 642b1 to 642b4 constitutes a “first external capacitance terminal”, and another arbitrary one of the terminals constitutes a “second external capacitance terminal”, and a regulator corresponding thereto The circuits constitute a “first regulator circuit” and a “second regulator circuit”, respectively.

  Further, as described above, the electronic device 1 has the sensor elements 7X, 7Y, and 7Z, and the IC chip 8 is operated by the first power supply voltage generated by the first regulator circuit, and the signal processing of the first sensor element. And a “second physical quantity signal processing circuit” that operates by the second power supply voltage generated by the second regulator circuit and performs signal processing of the second sensor element. Yes. Thereby, a plurality of physical quantities can be detected.

  Note that mismounting can be determined by the orientation of a chamfered portion 65 formed on the base 61 or characters printed on the electronic device 1.

When the electronic device 1A is attached to the measuring apparatus in a normal orientation, the manufacturing inspection board circuit 32 can be energized through the wiring 66, thereby determining that the electronic device 1A is attached in the normal orientation. . On the other hand, when the electronic device 1A is mistakenly attached to the measuring apparatus in a direction different from the normal direction, the manufacturing inspection board circuit 32 cannot perform energization through the wiring 66.
