The lock of the opening / closing part 25 is released by operating a lock release lever 9c shown in FIG. For this reason, for example, even if the protruding slider 5 does not return to its original state due to the engagement of the gear that drives the slider 5, the opening / closing portion 25 can be opened simply by operating the lock release lever 9 c. The finger attached to the cavity 20a can be removed urgently.

  The opening / closing portion 25 is generally “H” -shaped in Hiragana, and the inner peripheral side of the hollow portion 20 a is formed by a box-shaped inner peripheral housing portion 35, and the outer surface side is formed by a plate-shaped outer surface cover 36. Covered. The light receiving sensor 13 is housed in the inner peripheral housing portion 35 so that light emitted from the light emitting sensor 12 can be received through a hole formed in the inner peripheral housing portion 35 (see FIG. 3). That is, when the opening / closing part 25 is closed, the angle between the light receiving sensor 13 and the light emitting sensor 12 is orthogonal to the cavity part 20a, and the user's position is in the middle of the opposite side of the sensors 12 and 13. A finger is pressed, and a state in which light emitted from the light emitting sensor 12 is easily received by the light receiving sensor 13 is created so that a biological signal can be detected appropriately. The flexible circuit board 30 for the light receiving sensor 13 extends from one end 25 b of the opening / closing portion 25 and is drawn into the housing 20 from the hinge connecting portion 29, whereby the light receiving sensor 13 is connected to the box portion 51. Electrical connection is made with the signal processing unit 10a disposed inside (see FIG. 3).

  Next, the arrangement and attachment of the signal processing unit 10a (corresponding to the signal processing unit), the motor control unit 65 (corresponding to the motor control processing unit), the button battery B, and the operation unit 11 of the electrical equipment related parts included in the ring type device 1 Will be described. First, as shown in FIGS. 11A and 11B, the signal processing unit 10a, the button battery B, and the like are stacked and modularized as a control module 10. Specifically, the block-shaped signal processing unit 10a having a small thickness is mounted on the lower surface side in FIG. 11A of the main board 10b (corresponding to the first board), and FIG. 11A of the main board 10b. The upper surface side is attached to a rigid fixed angle 10e. Further, a battery holder 10c (corresponding to a battery housing portion) is attached to the upper surface side of the fixed angle 10e with a gap. In addition, as shown in FIG.11 (b), the opening 10f is formed in the center part of the battery holder 10c. A battery angle 10d having conductivity and elasticity is attached with screws on the upper surface side of the battery holder 10c, and an elastic piece 10g protruding from the battery angle 10d passes through the opening 10f of the battery holder 10c. Is growing.

  The button battery B is stored in a gap between the battery holder 10c and the fixed angle 10e. The stored button battery B is pressed against the fixed angle 10e by the elastic piece 10g, and the stored state is fixed. Electrical connection is made via the elastic piece 10g. The button battery B fixed in the battery holder 10c in this way is in a parallel posture with respect to each of the signal processing unit 10a and the main board 10b.

  In the control module 10 of FIGS. 11A and 11B, the first attachment portion 10 h of the fixed angle 10 e and the second attachment portion 10 i provided on the main board 10 b are attached to the first side cover 21. In the housing 20 (inside the box portion 51). In a state where the control module 10 is disposed inside the box portion 51, the control module 10 is disposed in an obliquely inclined posture (see FIGS. 4 and 6), and the oblique angle depends on the protruding direction of the slider 5 (arrow A in FIG. 1). The direction is inclined by 45 degrees with respect to the axial direction of the Z axis. For this reason, the main substrate 10b and the button battery B are arranged in the box portion 51 in a posture parallel to the protruding direction of the slider 5, thereby preventing a useless space from being generated in the box portion 51. At the same time, the height dimension h (see FIG. 1) of the box portion 51 along the Z-axis direction can be kept lower than when the control module 10 is arranged along the Z-axis direction.

A switch contact 11b, a fan-shaped jog switch 11c swinging left and right, a light emitting element (LED) 11d, and the like are mounted by soldering. A left jog switch 70 and a right jog switch 71 (see FIG. 12A) for detecting left and right swinging of the jog switch 11c are also mounted on the operation board 11a.

  The operation unit 11 is arranged inside the box unit 51 by screwing the operation board 11a to a fixed plate unit 2d (see FIG. 7) that is provided above the first peripheral plate unit 2b of the base chassis 2. Yes. Since the fixed plate portion 2d of the base chassis 2 is bent and formed so as to be parallel to the protruding direction of the slider 5, the operation board 11a fixed to the fixed plate portion 2d is also similar to the protruding direction of the slider 5. It becomes a parallel posture. Further, the operation unit 11 arranged and fixed in this way is in a state of being stacked with the above-described control module 10 without providing a useless space. Accordingly, the box unit 51 is also used for fixing the operation unit 11. As a result, it is possible to prevent the useless space from being generated in the interior of the box and to prevent the height h (see FIG. 1) of the box portion 51 from increasing. The operation switch 11b itself of the operation unit 11 has an end portion of a flexible extending portion welded to the inner surface of the top portion of the upper cover 24.

  Further, as shown in FIG. 2, the upper cover 24 is provided with holes 24a to 24c, and the operation switch 11b, jog switch 11c, and light emitting element 11d of the operation module 11 are respectively outside through the holes 24a to 24c. To the direction. Thereby, the user can perform various operations on the ring-type device 1 and can check the operation status by the light emission of the light emitting element 11d. In the ring type device 1 of the present embodiment, a flexible circuit board (FPC) is used for electrical connection between the respective electrical components.

  FIG. 12A is a block diagram showing an electrical connection relationship related to drive control of the motor 3 of the ring-type device 1. A left jog switch 70, a right jog switch 71, a motor 3, a termination sensor 7c, and a pressure sensor 14 are connected to a motor control unit 65 that performs control related to the motor 3. Further, the motor control unit 65 has an internal memory 65a. The motor control unit 65 stores a motor control program in the internal memory 65a and responds to a threshold for the pressure sensor 14 (according to a pressure value appropriate for detection of a biological signal). Etc.) are stored in advance. In addition, in the block diagram of Fig.12 (a), illustration of the electric power feeding line from the button battery B is abbreviate | omitted (FIG.12 (b) is also the same).

  When the user swings the jog switch 11 c in FIG. 2 to the left or right, an operation signal from the left jog switch 70 or the right jog switch 71 is input to the motor control unit 65. When an operation signal from the left jog switch 70 is input, the motor control unit 65 outputs a drive signal for rotating the motor 3 so that the slider 5 moves in the protruding direction. On the other hand, when an operation signal from the right jog switch 71 is input, the motor control unit 65 outputs a drive signal to the motor 3 for rotating the motor 3 so that the slider 5 moves into the box portion 51.

  When the motor control unit 65 outputs a drive signal for rotating the motor 3 in the direction in which the slider 5 protrudes to the motor 3, the value indicated by the detection signal from the pressure sensor 14 and the internal memory 65a store the value. A process of comparing the threshold value is performed. In this comparison processing, when the value indicated by the detection signal from the pressure sensor 14 becomes equal to or greater than the threshold value of the internal memory 65a, the motor control unit 65 can drive the drive signal even if the operation signal from the left jog switch 70 is input. Stop the output of. Thereby, it is possible to provide a finger pressing state that is optimal for detection of a biological signal. Further, when the detection signal from the end sensor 7c is input, the motor control unit 65 prevents the drive signal from being output even if the operation signal from the left jog switch 70 is input, while the right jog switch 71 The drive signal is output in response to only the input of the operation signal, and the occurrence of a failure due to excessive protrusion of the slider 5 is prevented.

  FIG. 12B is a block diagram showing an electrical connection relationship related to detection of a biological signal of the ring-type device 1, and includes an operation switch 11 b (switch contact), a light emitting sensor 12, and a light receiving sensor in the signal processing unit 10 a. 13 is connected. When the slider 5 protrudes due to the drive control of the motor 3 described above and the finger is in an optimal pressing state for detecting a biological signal, when the operation switch 11b is pressed down by the user, the signal processing unit 10a A control process for causing the light emission sensor 12 to emit light is performed. In addition, the signal processing unit 10a accepts a signal accompanying light reception by the light receiving sensor 13 along with light emission control of the light emitting sensor 12, and based on the received signal value, a value related to a biological signal (a pulse of a human body or oxygen in blood) A value indicating a saturated concentration) is calculated, and the calculation result is output through the wireless output unit 68. By this output processing, an external reception inspection device (not shown) can receive the detection result of the ring-type device 1, thereby making it possible to check the user's physical condition and the like.

  The ring-type device 1 according to the present invention is not limited to the above-described embodiment, and various modifications can be applied. For example, the projecting direction of the slider 5 is not limited to an angle with respect to the Z-axis direction of 45 degrees. When the height of the ring-type device 1 is further reduced, the angle with respect to the Z-axis direction is further increased. The slider 5 may be protruded in a more inclined direction.

  Further, the arrangement of the light emitting sensor 12 and the light receiving sensor 13 can be reversed from the above-described example. Further, an integrated sensor of a type in which the light emitting sensor 12 and the light receiving sensor 13 are integrated is used. It may be. In this case, it is preferable that the integrated sensor is disposed at the position of the light emitting sensor 12 in the above-described example because the wiring of the opening / closing part 25 can be omitted. However, the integrated sensor may be disposed in the opening / closing part 25. Of course it is possible. Furthermore, in addition to being attached to the slider 5, the pressure sensor 14 can also be attached to the inner peripheral surface of the cavity 20a facing the slider 5. In this case, the sensor amplifier board 15 is not located inside the slider 5. In the box unit 51 (for example, included in the control module 10). When the sensor amplifier substrate 15 is arranged in the box portion 51, the size of the slider 5 can be reduced and the degree of freedom in the protruding direction is increased, so that it is easy to design the ring-type device 1 with a reduced height.

  Further, the slider 5 is not driven by a motor, and a mechanism for manually projecting the slider 5 by rotating a dial-like member connected to a gear can be applied. Furthermore, in the above description, the ring-type device 1 has been described in the case of detecting a biological signal. However, the configuration according to the present invention is applied to a ring-type device for a remote controller for various electric device main bodies or game device main bodies. It is also possible. In this case, parts necessary for the remote controller are applied instead of the electrical parts related to the detection of the biological signal. Thus, if the configuration of the present invention is applied to a ring-type device for a remote controller, the height dimension h (see FIG. 1) of the box portion 51 can be kept low even if an inner diameter dimension adjusting mechanism is provided. User convenience can be improved.
