Description

  The present invention relates to an inspection apparatus, and more particularly to an inspection apparatus capable of rotating a display member that displays a bar-shaped image.

  The subjective visual vertical test (or subjective visual horizontal test) is a test that measures the difference between the subjective vertical position (or horizontal position) and the objective vertical position (or horizontal position) for the subject. It is. Non-Patent Document 1 proposes a telescope-type measuring apparatus as an apparatus used for this inspection. This apparatus has a cylindrical main body, and a dial is provided at one end of the main body. A target is attached to the inner surface of the dial, and the subject can look into the target in the dial through the main body from the other end of the main body. The subject arranges the main body horizontally and operates the dial while viewing the target to rotate the target. Then, a deviation between the position of the visual target recognized by the subject and the actual position of the visual target when it is arranged vertically is read from the dial angle scale.

Equilibrium Research Vol. 69 (6) 432-436, 2010

  In the apparatus of Non-Patent Document 1, when the subject's face is placed at a position where the target can be seen, the dial is naturally placed at the tip of the line of sight. Therefore, in order to operate the dial, the hand must be raised to the height of the line of sight. Thus, when the visual target is directly attached to the dial, the positional relationship between the dial and the subject is naturally fixed, and there is a possibility that the device becomes difficult to operate the dial.

  The objective of this invention is providing the inspection apparatus which is easy to improve operativity.

The inspection apparatus according to the present invention includes a housing having an opening that allows communication between the outside and the inside, and a rod-shaped image that is disposed in the housing and extends in a direction intersecting one direction toward the opening. A display member to be displayed; a first support member that rotatably supports the display member with respect to a first rotation axis along the one direction; and an operation that is separated from the housing with respect to a direction that intersects the one direction. A member, a second support member that rotatably supports the operated member with respect to a second rotation axis along the one direction, and the display member in the same direction as the rotation of the operated member First interlocking means for interlocking the operated member and the display member so as to rotate, and adjusting means capable of adjusting a force required to rotate the operated member with respect to the second rotation axis. , Direction of rotation of the third rotating shaft An encoder that detects a position related to the second rotation axis, and a second link that links the display member and the third rotation shaft so that the third rotation shaft rotates in the same direction as the rotation of the display member when the display member rotates. Interlocking means .

  By providing interlocking means for interlocking the operated member and the display member, the operated member can be arranged separately from the casing. For this reason, the positional relationship between the operated member and the display member can be adjusted relatively freely. Therefore, an apparatus configuration that can easily improve operability is realized. For example, if the operated member is disposed below the housing, the subject does not need to raise his hand for operation.

FIG. 3B is an enlarged view of the vicinity of the stopper bolt of FIG. It is a left view of the disk member arrange | positioned in the inspection apparatus of FIG. It is a block diagram which shows the electrical structure around a control part. It is a flowchart which shows the flow of the test | inspection implemented using an inspection apparatus.

  An inspection apparatus 1 according to an embodiment of the present invention will be described with reference to FIGS.

  The inspection device 1 has a main body 2 as shown in FIG. The main body 2 includes a cylindrical portion 3, a control box 4, and a transmission mechanism housing portion 5. The cylindrical part 3, the control box 4, and the transmission mechanism accommodation part 5 accommodate a plurality of members therein. The transmission mechanism accommodating portion 5 is fixed to one end of the cylindrical portion 3 with the fixing plate 16 in between in the horizontal direction. The transmission mechanism accommodating portion 5 extends slightly above the cylindrical portion 3. The control box 4 is disposed on the upper surface of the cylindrical portion 3 between the cylindrical portion 3 and the upper portion of the transmission mechanism accommodating portion 5, and is fixed to the cylindrical portion 3 and the transmission mechanism accommodating portion 5.

  A first leg 21 to a third leg 23 are fixed to the lower portion of the main body 2. The first leg portion 21 has an upper portion 21a and a lower portion 21b. The upper portion 21 a is fixed to the end portion of the cylindrical portion 3 on the side opposite to the transmission mechanism housing portion 5. The lower part 21b can be attached to and detached from the upper part 21a. A horizontal portion 25 is fixed to the lower end of the lower portion 21 b of the first leg portion 21. The grounding portion 24 is fixed to each of both ends of the horizontal portion 25 so that the position in the vertical direction can be adjusted by rotating it in the direction of arrow A in FIG. The 2nd leg part 22 and the 3rd leg part 23 have the mutually same structure, and consist of an upper part and a lower part, respectively. For example, the upper portion 22 a of the second leg portion is fixed to the lower end portion of the fixing plate 16. The lower part 22b is detachable with respect to the upper part 22a. A grounding portion 24 is fixed to the lower end of the lower portion 22b so that the position in the vertical direction can be adjusted by rotating it in the direction of arrow B in FIG.

  As described above, each of the first leg portion 21 to the third leg portion 23 is configured such that the lower portion can be attached to and detached from the upper portion. As a result, when the apparatus is used, the lower part is attached to the upper part and used, and when not used, the lower part is removed from the upper part and the entire apparatus can be compactly accommodated in a box or a shelf. Further, since the position of the grounding portion 24 can be adjusted with respect to the vertical direction, the apparatus main body 2 can be arranged horizontally even if there is some inclination or unevenness on the table or the floor on which the apparatus is placed. Hereinafter, in the description regarding the direction of each member, it is assumed that the apparatus main body 2 is arranged horizontally.

  Next, each of the cylindrical part 3, the control box 4, and the transmission mechanism accommodating part 5 is demonstrated in detail. The cylindrical portion 3 has a cylindrical casing. This housing is arranged so that the central axis is along the left-right direction in FIG. 1 (one direction in the present invention). An opening 3a is formed at one end of the housing, and the inside and outside of the cylindrical portion 3 communicate with each other through the opening 3a. A window 6 is provided in the opening 3a.

  The window portion 6 is formed of an elastic sponge-like elastic material such as urethane foam. As the elastic material, other elastic materials such as rubber may be used. As shown in FIGS. 1 and 2, the window portion 6 has a cylindrical shape, and has a substantially elliptical shape in FIG. 2. When the subject presses the upper part of the face against the window part 6 from the side, the window part 6 is adjusted to a size that allows both eyes to fit in the opening 3 a of the window part 6. The window part 6 is arrange | positioned in the exact center of the cylindrical part 3 regarding the perpendicular direction. When the periphery of both eyes of the subject is pressed against the window portion 6, the face easily adheres to the window portion 6 without a gap due to deformation of the elastic material. When the face of the subject is in close contact with the window portion 6 without a gap, the window portion 6 is sealed.

  A hollow disk member 7 (display member) is provided in the cylindrical portion 3. As shown in FIG. 4, a slit 7a is formed on the circular surface of the disk member 7 along its diameter. The slit 7a extends from the vicinity of one end of the diameter to the vicinity of the other end. As shown in FIG. 1, a tube-shaped light emitter 31 is provided in the disk member 7. The light emitter 31 may be any type of light emitter such as a neon tube or LED. On, off, and intensity of light emitted from the light emitter 31 are controlled by a control unit 32 described later.

  As shown in FIG. 1, the disk member 7 is disposed in the cylindrical portion 3 at the end opposite to the window portion 6 in the horizontal direction and in the center of the cylindrical portion 3 in the vertical direction. When the light emitter 31 is turned on, the light from the light emitter 31 is emitted toward the window 6 through the slit 7a. Thereby, the disk member 7 displays a rod-shaped image along the slit 7 a toward the window portion 6. In the disk member 7, a disk shaft 8 is fixed to the side surface opposite to the window portion 6. The disk shaft 8 is along the left-right direction in FIG. 1 and is disposed at the position of the central axis of the disk member 7.

  No members other than the disk member 7 and the disk shaft 8 are provided in the cylindrical portion 3, and the portions other than the disk member 7 are hollow. Moreover, if the window part 6 is sealed, the inner surface of the cylindrical part 3 has a light shielding property as strictly as possible so that light other than the light from the disk member 7 does not enter the space in the cylindrical part 3. Preferably it is. If light from other than the disk member 7 enters and the geometric structure in the cylindrical portion 3 is visible, the subject can easily infer the vertical direction from the comparison with the structure in the cylindrical portion 3, and the accuracy of the inspection is reduced. It is because there is a possibility of doing.

  A handle 9 is provided below the cylindrical portion 3. The handle 9 is fixed to a handle shaft 10 along the left-right direction in FIG. The handle shaft 10 is rotatably supported by the handle shaft support member 40. The handle shaft support member 40 is a member of the transmission mechanism 100 described later.

  The transmission mechanism housing 5 has a housing that opens downward. Housed in the housing is a transmission mechanism 100 that transmits a driving force generated by the rotation of the handle 9 to the disk member 7 and an encoder 33 described later. The transmission mechanism 100 has a support member 17 that supports the disk shaft 8. The disk shaft 8 is rotatably supported by the support member 17 at one end and the fixed plate 16 near the other end.

  Further, the transmission mechanism 100 includes a handle shaft support member 40, a first pulley 11 to a third pulley 13, and a first belt 14 and a second belt 15. The handle shaft support member 40 is supported on the fixed plate 16 by a shaft support portion 41 so as to be rotatable in the direction of arrow C in FIG. The handle shaft support member 40 includes an arm portion 40a that extends obliquely downward from the shaft support portion 41, and a protruding portion 40b that protrudes upward from the vicinity of the lower end of the arm portion 40a. A grip 42 protruding rightward in FIG. 1 is fixed to an end of the arm 40a opposite to the shaft support 41. A shaft support portion 43 that rotatably supports the handle shaft 10 is provided substantially at the center in the length direction of the arm portion 40a.

  In the arm portion 40 a, a stopper plate 44 is fixed between the shaft support portion 41 and the shaft support portion 43. The stopper plate 44 is fixed to the side surface of the arm portion 40a that faces diagonally downward to the left in FIG. In FIG. 3A, a stopper bolt 45 is disposed further diagonally to the left of the stopper plate 44. The stopper bolt 45 is attached to the fixed plate 16 by a support metal fitting 46. The support fitting 46 is rotatably supported by the fixed plate 16 so that the bolt head swings along the arrow E in FIG. The screw portion of the stopper bolt 45 is fitted in the screw hole on the support metal fitting 46 side. When the stopper bolt 45 is rotated, the bolt head can be taken in and out from the support fitting 46 along the arrow D toward the stopper plate 44 as shown in FIG. Normally, the stopper bolt 45 is disposed in a state where the surface of the bolt head is in contact with the side surface of the stopper plate 44 in parallel. As a result, the handle shaft support member 40 is supported by the stopper bolt 45.

  As shown in FIG. 3A, the protrusion 40b is curved so as to be substantially along the rotation direction along the arrow C, and a slit 40c extending along the rotation direction is formed. The screw portion of the fastener 47 passes through the slit 40c. The screw portion of the tightening tool 47 passes through the slit 40 c and is fitted with a screw hole formed in the fixing plate 16. By tightening the fastening tool 47 with respect to the fixing plate 16, the protruding portion 40 b can be sandwiched and fixed between the fastening tool 47 and the fixing plate 16. Conversely, when the tightening tool 47 is loosened with respect to the fixed plate 16, the handle shaft support member 40 can be rotated in the direction of the arrow by grasping and moving the grip 42.

  As shown in FIG. 3A, each of the first pulley 11 to the third pulley 13 has a disk shape, and a large number of teeth are arranged on the circumferential surface along the circumferential direction. The first pulley 11 (first rotating body) and the second pulley 12 (second rotating body) have the same size, and the tooth configuration is the same. The third pulley 13 is the largest of these pulleys. As shown in FIG. 1, the first pulley 11 is disposed at a position where the shaft support portion 43 is sandwiched between the first pulley 11 and the handle 9. A shaft 11 a extending along the left-right direction in FIG. 1 is fixed to the first pulley 11, and this shaft 11 a is connected to the handle shaft 10. The second pulley 12 and the third pulley 13 are fixed to the disk shaft 8. The first belt 14 (transmission member) is stretched between the first pulley 11 and the second pulley 12, and the second belt 15 is stretched between the third pulley 13 and a shaft 33a of an encoder 33 described later. Has been passed. On the peripheral surface of the first belt 14 on the pulley side, teeth that are configured to mesh with the teeth of the first pulley 11 and the teeth of the second pulley 12 are arranged along the circumferential direction. On the peripheral surface of the second belt 15 on the pulley side, teeth configured to just mesh with the teeth of the third pulley 13 and the teeth of the shaft 33a of the encoder 33 (described later) are arranged along the circumferential direction.

  The transmission mechanism 100 has a defining mechanism that defines the reference position of the disk member 7. The reference position of the disk member 7 is a position (position shown in FIG. 4) where the slit 7a is arranged along the vertical direction. The defining mechanism includes a hole formed in each of the third pulley 13 and the fixed plate 16 and an adjustment pin 51. The positions of the two holes are adjusted so that the slit 7a of the disk member 7 is just along the vertical direction when they coincide with each other from the viewpoint of FIG. The adjustment pin 51 has a diameter slightly smaller than the hole. The disk member 7 can be arranged at the reference position by inserting the adjustment pin 51 into both holes after aligning the positions of the holes.

  Hereinafter, the function of the transmission mechanism 100 will be described. When the user or the subject rotates the handle 9, the driving force generated thereby is transmitted to the disk shaft 8 via the handle shaft 10, the first pulley 11, the first belt 14 and the second pulley 12. Thereby, the disk member 7 rotates by the same angle in the same direction as the subject rotates the handle 9.

  Here, the force required for the subject to rotate the stationary handle 9 increases as the tension acting on the first belt 14 in a stationary state increases. This is because the tension of the first belt 14 becomes a force that resists the rotation of the first pulley 11. If the force required to rotate the handle 9 is too great for the subject, there is a possibility that the inspection by this apparatus cannot be carried out smoothly. On the other hand, if the first belt 14 is too slack, even if the handle 9 is rotated, the teeth of the first belt 14 do not mesh with the teeth of the first pulley 11 and the teeth of the second pulley 12, and the driving force is transmitted smoothly. There is also a risk that it will not be.

  Therefore, in the present embodiment, by rotating the handle shaft support member 40 as follows, the tension of the first belt 14, that is, the magnitude of the force resisting the rotation of the first pulley 11 can be adjusted. First, when the first belt 14 is too loose, the tightening tool 47 is loosened, and the stopper bolt 45 is retracted from the stopper plate 44 and separated (see FIG. 3B). Thereby, a space necessary for rotating the handle shaft support member 40 clockwise in FIG. 3B can be secured between the stopper bolt 45 and the stopper plate 44.

  Then, the handle shaft support member 40 is rotated clockwise. Thereby, since the rotating shaft of the 1st pulley 11 connected with the handle shaft 10 moves below, the distance between the 1st pulley 11 and the 2nd pulley 12 becomes large. Therefore, the tension of the first belt 14 becomes strong. In this state, the tightening tool 47 is fastened to the fixing plate 16 to fix the handle shaft support member 40. Further, the stopper bolt 45 is protruded toward the stopper plate 44 and the support fitting 46 is rotated in the direction of arrow E in FIG. 3B so that the surface of the bolt head is arranged in parallel with the surface of the stopper plate 44. Adjust the position of the stopper bolt 45 as described above. As a result, the stopper bolt 45 is brought into contact with the stopper plate 44 to support the stopper plate 44.

  On the other hand, if the first belt 14 is too tight, the handle 47 is rotated counterclockwise in FIG. Thereby, since the rotating shaft of the 1st pulley 11 connected with the handle shaft 10 moves upwards, the distance between the 1st pulley 11 and the 2nd pulley 12 becomes small. Therefore, the tension of the first belt 14 is weakened. Then, the stopper bolt 45 is protruded toward the stopper plate 44 and the support fitting 46 is rotated in the direction of arrow E in FIG. 3B so that the surface of the bolt head is arranged parallel to the surface of the stopper plate 44. Adjust the position of the stopper bolt 45 as described above. As a result, the stopper bolt 45 is brought into contact with the stopper plate 44 to support the stopper plate 44.

  In the transmission mechanism 100 of the present embodiment, the first pulley 11, the second pulley 12, and the first belt 14 that interlock the handle 9 and the disk member 7 correspond to the first interlocking means in the present invention. Further, the second pulley 12 and the second belt 15 for interlocking the disk member 7 and the shaft 33a of the encoder 33 correspond to the second interlocking means in the present invention. Furthermore, the handle shaft support member 40, the tightening tool 47, the stopper plate 44, and the stopper bolt 45 that are configured to be able to adjust the distance between the first pulley 11 and the second pulley 12 correspond to the adjusting means in the present invention.

  As shown in FIG. 3A, a display 52 and operation buttons 53 are provided on the side surface of the transmission mechanism housing 5. The display device 52 is a device that digitally displays a symbol such as a numerical value of up to 5 digits, a character, and a sign. The display 52 displays a symbol such as a numerical value based on a control signal from the control unit 32 described later. The operation button 53 is a button for the user to operate the state of the apparatus. The transmission mechanism accommodating portion 5 is provided with a connecting portion 5a to which a cable from the button box 54 is connected. On the upper surface of the button box 54, a decision button 55 to be pressed by the subject is provided. When the operation button 53 and the determination button 55 are pressed, signals indicating the button press are output to the control unit 32 described later.

  The control box 4 mainly accommodates the electrical system configuration of the apparatus such as an electronic board and various switches on the surface and inside. As shown in FIG. 1, a power switch 61 and a brightness adjustment switch 62 are provided on the side surface of the control box 4. The power switch 61 is a switch for switching the inspection apparatus 1 on and off. The brightness adjustment switch 62 is formed with a cross groove, and can be rotated with a Phillips screwdriver. The position of the brightness adjustment switch 62 in the rotational direction corresponds to the brightness of the light emitter 31. For example, this corresponds to the fact that the intensity of light from the light emitter 31 increases as the brightness adjustment switch 62 is rotated clockwise from the viewpoint of FIG. A signal indicating the position of the brightness adjustment switch 62 is output to the control unit 32 described later. A level 63 is provided on the upper surface of the control box 4. The main body 2 can be arranged horizontally by adjusting the position of the grounding portion 24 in the vertical direction according to the display of the level 63.

  An encoder 33 and a control unit 32 are provided in the control box 4. As described above, the second belt 15 is stretched between the third pulley 13 and the shaft 33a of the encoder 33. The shaft 33a has teeth formed so as to mesh with the teeth formed on the second belt 15. Further, the shaft 33a has a considerably smaller diameter than the third pulley 13 as shown in FIG. The encoder 33 measures the position of the shaft 33a with respect to a predetermined zero point position in the rotation direction, and outputs the measurement result to the control unit 32. For example, when the shaft 33a rotates clockwise by α degrees (α> 0) with respect to the zero point position from the viewpoint of FIG. 3A, a signal indicating + α is output to the control unit 32. On the other hand, when the shaft 33a rotates β degrees (β> 0) counterclockwise with respect to the zero point position, a signal indicating −β is output to the control unit 32. When a predetermined control signal is input from the control unit 32, the encoder 33 updates the position of the shaft 33a at that time to the zero position.

  The control unit 32 includes a storage device such as a processor and a memory, hardware including various electronic components, and software stored in the storage device. The function of the control unit 32 is realized by the software and hardware functioning together. As shown in FIG. 5, signals are input from the operation button 53, the determination button 55, the encoder 33, and the brightness adjustment switch 62 to the control unit 32. The control unit 32 controls the encoder 33, the display 52, and the light emitter 31 based on these input signals. Hereinafter, a series of control by the control part 32 is demonstrated along the flow in which a user performs an inspection using this apparatus. FIG. 6 is a flowchart showing the flow of inspection.

  First, the user turns on the power switch 61 (step S1). At this time, the control unit 32 displays a symbol or the like indicating activation on the display 52, and then causes the display 52 to display a symbol or the like indicating a standby state immediately after activation. And the control part 32 turns on the light-emitting body 31 as shown in FIG. At this time, the control unit 32 controls the light emitter 31 so as to emit light having a brightness corresponding to the input signal from the brightness adjustment switch 62. Hereinafter, when the light emitter 31 is in the ON state, the control unit 32 adjusts the intensity of light from the light emitter 31 based on the input signal from the brightness adjustment switch 62.

  Next, the user aligns the holes formed in each of the third pulley 13 and the fixing plate 16 and pierces the adjustment pin 51 through both holes. Thereby, the disk member 7 is set to the reference position (step S2). Next, the user presses the operation button 53 for a long time (step S3). When the control unit 32 determines that the period during which the operation button 53 remains pressed exceeds a predetermined length, the control unit 32 outputs to the encoder 33 a control signal instructing to update the zero point position. Thereby, the encoder 33 resets the time when the disk member 7 is in the reference position to the zero point position. In addition, the control unit 32 turns off the light emitter 31.

  Note that while the operation button 53 is being pressed for a long time, the control unit 32 may display a symbol or the like indicating the length of time for which the operation button 53 is pressed on the display 52. For example, when a long press of the operation button 53 is started, a plurality of bars are displayed on the display 52 as “----”. While the operation button 53 is being pressed, the bars are erased one by one. When a predetermined time has elapsed and all the bars are erased, the zero point position is updated, and “0 °” indicating that the zero point position has been updated is displayed on the display 52.

  Next, after removing the adjustment pin 51 from the hole, the user rotates the handle 9 by a predetermined angle (for example, +40 degrees) from the reference position, and initializes the position of the handle 9 (step S4). Next, the user presses the operation button 53 (step S5). Based on the input signal from the operation button 53 indicating that the operation button 53 is pressed, the control unit 32 turns on the light emitter 31 and starts the inspection mode. In the inspection mode, the subject looks into the cylindrical portion 3 from the window portion 6 and rotates the handle 9 while visually observing the rod-shaped image displayed on the disk member 7 (step S6). When the subject recognizes that the image on the disk member 7 is perpendicular, the subject presses the enter button 55 (step S7).

  Based on the input signal from the enter button 55 indicating that the enter button 55 has been pressed, the control unit 32 displays the angle indicated by the input signal from the encoder 33 at that time on the display 52 and maintains the display ( Step S8). In addition, the control unit 32 turns off the light emitter 31. The user enters the inspection result based on the display on the display 52. Then, the user rotates the handle 9 by a predetermined angle (step S9). When the control unit 32 determines that the disk member 7 has rotated by a predetermined angle (for example, 5 degrees) or more from the reference position based on the input signal from the encoder 33, the one inspection is finished. And the process from step S4 regarding the next test | inspection is repeated.

  According to the inspection apparatus of this embodiment described above, the handle 9 is disposed below the cylindrical portion 3. For this reason, when the subject operates the handle 9 while visually observing the inside of the cylindrical portion 3, the hand can be placed below the position of the face, which is easy to operate. Further, the distance between the first pulley 11 and the second pulley 12 can be changed by rotating the handle shaft support member 40. Thus, the tension of the first belt 14 can be adjusted so that the subject can rotate the handle 9 smoothly. Furthermore, since the window part 6 consists of an elastic material, when pressing a face, the window part 6 is easy to be sealed, and the light from the outside cannot enter the cylindrical part 3 easily. For this reason, compared with the case where light is easy to enter and the structure in the cylindrical portion 3 is easily visible, the accuracy of inspection is high.

  Hereinafter, modifications of the present embodiment will be described.

[1] In the above-described embodiment, the encoder 33 detects the angle of the disk member 7 from the reference position, and the display 52 displays the angle. However, for example, a scale related to the angle is formed on the second pulley 12, and the apparatus may be configured so that the inspection result can be detected by the user visually reading the scale.

[2] In the above-described embodiment, the interlocking means for interlocking the handle 9 and the disk member 7 is constituted by a pulley and a belt. However, the interlocking means may be configured by other than these. For example, a plurality of gears may be provided instead of the pulley and the belt, and the interlocking means may be configured so that the gears transmit the rotation of the handle 9 to the disk member 7. In this case, it is preferable that a configuration for generating a force against the rotation of the handle 9 and the gear and a configuration for adjusting the force are provided. For example, it is considered to provide a brake member that abuts on the handle shaft 10 or the shaft of the gear and generates a frictional force against the rotation of the handle shaft 10 and a gear and an adjustment mechanism that can adjust the force pressing the brake member against the shaft. It is done. According to this modification, the gear corresponds to the transmission member of the present invention.

[3] In the above-described embodiment, the tube-shaped light emitter 31 is provided as a light source in the disk member 7. However, a plurality of LED bulbs may be arranged in a straight line. In addition, other display methods such as a liquid crystal display may be used.

[4] In the above-described embodiment, it is assumed that the subjective visual vertical inspection is mainly performed, but the present invention may be applied to the case where the subjective visual horizontal inspection is performed. In this case, the apparatus may be configured so that the position where the slit 7 a is disposed horizontally becomes the reference position of the disk member 7.

[5] In the above embodiment, the light emitter 31 is turned on or off according to the flow of inspection. However, the apparatus may be configured to be able to switch between a mode in which the on / off state of the light emitter 31 changes and a mode in which the light emitter is always on during the period when the power of the apparatus is on. .
