[Overview]
Embodiments of the present disclosure will be described. The items classified in <> below can be used independently or in conjunction with each other. For example, in some embodiments, multiple items may be combined as appropriate.

The electric optical table (for example, the electric optical table 10) of the present embodiment is an electric optical table for placing an inspection apparatus (for example, the inspection apparatus 100) used for examining an eye to be examined. The inspection device may be a stationary device such as a fundus imaging device, an eye refractive power measuring device, or the like. For example, the inspection apparatus may have face support means (for example, forehead rest, chin rest, etc.) for supporting the subject's face, and inspection means for inspecting the subject's eye. The inspection device is placed on the top plate so that the face support means is positioned at the second end of the top plate and the working distance direction of the inspection means matches the longitudinal direction of the top plate. (The top plate will be described later).

For example, the motorized optical table includes a top plate (for example, top plate 1) on which the inspection device is placed. For example, the motorized optical table includes a support (for example, support 30) that supports the top plate. The column has driving means (for example, a vertical movement mechanism 31) for moving the top plate in the vertical direction with respect to the floor surface. For example, the motorized optical table includes legs (for example, legs 4) that support the support on the floor.

Furthermore, for example, the motorized optical table of the present embodiment may include operation means (eg, lever 5) used by the examiner to adjust the height of the tabletop. For example, the operation means may include a first operation means (for example, lever 5) for inputting a first operation signal for automatically moving the table top up and down by the operation of the examiner. Further, for example, the operation means may include a second operation means (e.g., lever 5) for inputting a second operation signal for manually moving the top plate up and down by operation of the examiner. Further, for example, the motorized optical table may include control means (for example, the control section 70) that controls driving of the drive means provided on the column.

<Top plate>
The top plate may be any size as long as the inspection device can be placed thereon. For example, the top plate may be rectangular in shape and have a longitudinal direction and a lateral direction. A column is connected to a first end (for example, a first end Ta) in the longitudinal direction of the top plate. Detecting means for detecting proximity between the subject and the tabletop is provided at a second end (for example, the second end Tb) opposite to the first end in the longitudinal direction of the tabletop. More specifically, detection means are provided for detecting proximity between the subject's leg or arm and the lower surface of the tabletop. Note that the first end and the second end of the top plate may not be strictly the ends of the top plate.

<Strut>
One end of the post is connected to the first end in the longitudinal direction of the top plate on the lower surface of the top plate. For example, the first end may be at a position that takes into account the position of the subject's feet. For example, it may be at a position distant from the second end to the extent that the subject's foot does not come into contact with the support during examination. According to this, contact between the legs of the subject and the support can be suppressed during the examination, so that the subject can be examined in a correct posture.

Note that the support may be arranged so that contact with the subject's leg is suppressed even when the subject stretches the leg. In this case, the post may be arranged in the center of the top plate in the width direction. Alternatively, the struts may be arranged at either end of the top plate in the short direction.

In this embodiment, a column is arranged below the inspection device via a top plate. For example, a post may be arranged in the area of the top board on which the inspection device is placed. According to this, since the top plate can be made small, the installation area of the electric optical table can be reduced.

The other end of the support is connected to the leg. For example, the strut may be connected to a first member, which will be described later, that constitutes the leg. Also, for example, the post may be connected to a second member that constitutes the leg, which will be described later.

<Leg>
The leg is connected to the support and supports the support on the floor. For example, the legs have first members (eg, ground members 4b and 4c) extending in the longitudinal direction of the top plate. A plurality of first members may be provided. Note that the first member may be a member that extends substantially in the longitudinal direction of the top plate. For example, in this case, the longitudinal direction of the first member may extend parallel (substantially parallel) to the longitudinal direction of the top plate. That is, the longitudinal direction of the first member may coincide with the longitudinal direction of the top plate. Further, in this case, the longitudinal direction of the first member may extend in a direction obliquely crossing the longitudinal direction of the top plate.

For example, the first member may be a member that extends longitudinally along the edge of the top plate. In this case, a space is formed between the detection means provided at the second end of the top plate and the floor surface. According to this, since the subject's feet can be placed in the formed space during the examination, the subject can be examined in a comfortable posture.

For example, the first member is arranged to fit under the top plate. For example, the longitudinal dimension of the first member may be the same as the longitudinal dimension of the top plate. Further, for example, the longitudinal dimension of the first member may be less than the longitudinal dimension of the top plate. According to this, since the legs do not protrude from the top plate, it is possible to suppress an increase in the installation area of the electric optical table. Also, the electric optical table can be arranged so that the first end side of the top plate is close to the wall surface.

The leg may have a second member (for example, connecting member 4a) extending in the lateral direction of the top plate. A plurality of second members may be provided. In addition, the second member may be a member that substantially extends in the short direction of the top plate. For example, in this case, the longitudinal direction of the second member may extend parallel (substantially parallel) to the lateral direction of the top plate. That is, the longitudinal direction of the second member may coincide with the lateral direction of the top plate. Further, in this case, the longitudinal direction of the second member may extend in a direction obliquely crossing the lateral direction of the top plate.

For example, the second member is arranged to fit under the top plate. For example, the lengthwise dimension of the second member may be the same as the widthwise dimension of the top plate. Further, for example, the lengthwise dimension of the second member may be smaller than the widthwise dimension of the top plate. According to this, since the legs do not protrude from the top plate, it is possible to suppress an increase in the installation area of the electric optical table. Also, the electric optical table can be arranged so that the side surface of the inspection apparatus is brought close to the wall surface.

In this embodiment, the strut and the first member may be connected via the second member. That is, the support may be connected to the second member, and the first member may be connected to the second member, thereby connecting the support to the leg. The second member may be connected to one end of the first member. The one end of the first member may not be strictly the end of the first member. In addition, by arranging the support at the first end in consideration of the position of the subject's feet with respect to the top plate, the second member connected to the support is also a predetermined distance from the second end of the top plate. placed a distance apart. According to this, contact between the subject's foot and the second member is suppressed during the examination, and the subject can be examined in an appropriate posture.

<Operation means>
In this embodiment, the motorized optical table may be provided with an operation means for the examiner to adjust the height position of the top plate. For example, the operating means includes a first operating means (e.g., lever 5) for inputting a first operation signal for automatically moving the top plate up and down to a first position or a second position lower than the first position. good too. For example, the first position and the second position are height positions (set positions) set in advance within a movable range of the tabletop. As an example, the first position may be the upper limit position to which the top plate can move. Also, as an example, the second position may be the lower limit position to which the top board is movable. Of course, the first position and the second position may be positions different from the upper limit position and the lower limit position. In this embodiment, the first operation signal may include a signal for automatically moving the table top up and down to a third position between the first position and the second position. Note that there may be a plurality of such intermediate positions. The operating means may also include a second operating means (e.g., lever 5) for continuously inputting a second operating signal for manually moving the top plate up and down to an arbitrary position.

For example, the first operating means and the second operating means may be levers, switches, foot pedals, or the like provided on the motorized optical table. Also, the first operating means and the second operating means may be external devices that can be connected to the electric optical table by wire or wirelessly. In addition, for example, the first operating means and the second operating means may be provided separately or may be used together.

In this embodiment, the first operating means and the second operating means may be levers that share their respective functions. For example, the input of the first operation signal and the input of the second operation signal may be switched according to the operation amount of the lever operated by the examiner. In this case, the first operation signal may be input if the amount of operation of the lever is equal to or greater than the threshold, and the second operation signal may be input if the amount of operation of the lever is less than the threshold.

<Control means>
The control means controls driving of the driving means of the support based on the operation signal from the operation means. As a result, the height position of the top plate moves up and down. For example, the control means automatically moves the top plate up and down based on the first operation signal input from the first operation means. More specifically, the tabletop is vertically moved from the current position to the first position or the second position based on the first operation signal. In addition, the control means moves the top plate to the first position or the second position by receiving the first operation signal even if the examiner releases the first operation means. According to this, the examiner can perform other work while moving the tabletop according to the height of the examinee.

Of course, the control means may automatically move the table top up and down from the current position to the third position based on the first operation signal. According to this, since the tabletop can be changed step by step, even if the examiner roughly moves the tabletop according to the height of the examinee, etc., it is possible to find an appropriate table for each examinee. Easier to adjust height.

For example, the control means moves the tabletop based on the second operation signal input from the second operation means. More specifically, the table top is vertically moved from the current position to an arbitrary position based on the second operation signal. At this time, the control means vertically moves the tabletop to an arbitrary position in response to continuous second operation signals input by the examiner's continuous operation of the second operation means. According to this, the examiner can finely adjust the height of the tabletop according to the height of the examinee.

In the present embodiment, when the control means detects the input of the second operation signal from the second operation means while driving the tabletop based on the first operation signal from the first operation means, the first operation means The driving of the tabletop based on the signal may be stopped, and the driving of the tabletop based on the second operation signal may be executed. This allows the examiner to efficiently adjust the height of the tabletop.

[Example]
An example of this embodiment will be described with reference to the drawings.

FIG. 1 is a schematic diagram showing an electric optical table 10 on which an inspection apparatus 100 is placed. For example, the inspection device 100 includes a face support section 102 fixed to a base 101 . A vertically movable chin rest 103 is provided on the face support portion 102 . A horizontally movable table 105 is provided on the base 101, and an inspection unit 106 having an inspection optical system is mounted on the mobile table 105. As shown in FIG. Incidentally, the chin rest 103 and the examination section 106 are electrically driven by a drive mechanism (not shown), the chin rest 103 in the vertical direction and the examination section 106 in the three-dimensional direction.

The inspection apparatus 100 is placed so that the front-rear direction (working distance direction) of the inspection apparatus 100 and the longitudinal direction of the top plate 1 of the electric optical table 10 match. Also, the examination apparatus 100 is placed so that the chin rest 103 is positioned on the side of the second end Tb (described later) of the top plate 1 . In this embodiment, the horizontal direction of the inspection apparatus 100 is defined as the x direction of the electric optical table 10 . Also, the vertical direction of the inspection apparatus 100 is defined as the y direction of the electric optical table 10 . Also, the front-rear direction of the inspection apparatus 100 is defined as the z-direction of the electric optical table 10 .

FIG. 2 is an external configuration diagram of the electric optical table 10. As shown in FIG. FIG. 2(a) is a perspective view of the motorized optical table 10 as viewed from below. FIG. 2B is a perspective view of the electric optical table 10 as seen from above.

The electric optical table 10 is roughly divided into a top board (table) 1 on which an inspection apparatus 100 is placed, a column 30 for supporting the top board 1 from below, and a column 30 that allows the entire electric optical table 10 to be placed on the floor. and a leg 4 for supporting with. The support 30 secures a sufficient space below the top plate 1 and is attached at a position where it does not come into contact with the subject's feet, wheelchair, etc. during examination (details will be described later). In addition, in this embodiment, a storage box 2 for storing wiring and circuits is provided on the back surface of the top plate 1. As shown in FIG. A power switch 8 for the electric optical table 10 and a lever 5 for vertically moving the post 30 are provided at the end of the storage box 2 . A switch mechanism 20 is provided on the back surface of the tabletop 1 facing the subject. is provided.

In addition, the lever 5 is electrically connected to a vertical movement mechanism 31 for the post 30 to be described later via a circuit and wiring housed in the housing box 2 . By using the lever 5, the column 30 can be moved up and down (details will be described later).

<Top plate>
FIG. 3 is a top view of the top plate 1. FIG. The top plate 1 has a size on which the inspection device 100 can be placed. For example, the size of the top board 1 is the same size as the base 101 of the inspection apparatus 100 . Of course, the size of the top plate 1 is not limited to this.

For example, the top plate 1 has a rectangular shape. A post 30, which will be described later, is connected to one end (first end Ta) of the top plate 1 in the longitudinal direction. In addition, the subject is positioned at the other end (second end Tb) of the top plate 1 in the longitudinal direction during examination (see FIGS. 1 and 4). In this embodiment, the end does not have to be strictly the end of the top plate, and the post 30 is arranged at a position closer to the center from the end of the top plate 1 (see FIG. 4).

The width d of the top plate 1 in the lateral direction is designed in consideration of a subject using a wheelchair. Specifically, for example, the width d in the lateral direction is designed to be shorter than the length between the left and right armrests AR of the wheelchair. (See Figure 1). As a result, the subject can avoid contact between the wheelchair and the top board 1, can easily approach the examination apparatus 100, and can undergo the examination in a comfortable posture.

<Strut>
4A and 4B are diagrams for explaining the arrangement of the pillars 30 with respect to the top plate 1. FIG. For example, a post 30 is connected to the back surface of the top plate 1 . For example, the post 30 is connected to the first end Ta in the longitudinal direction on the back surface of the top plate 1 . Further, for example, the post 30 is arranged at a position separated by a distance Le or more from the second longitudinal end portion Tb of the top plate 1 . The distance Le is the length in the z-direction required for placing the feet under the tabletop 1 when the subject approaches the tabletop 1 (inspection apparatus 100) when performing the examination while sitting. be. Further, the distance Le is the length in the z-direction required for placing the feet under the tabletop 1 when the subject uses a wheelchair (see FIGS. 2 and 4). For example, the distance Le is a predetermined length.

For example, the pillars may be arranged inside the top plate 1 . Preferably, it may be arranged inside the area of the top plate 1 on which the inspection apparatus 100 is placed. According to this, it is not necessary to provide a space for arranging the struts in addition to the space for arranging the inspection device, so that the installation area of the electric optical table can be reduced.

For example, in this embodiment, the post 30 is arranged on the central axis C of the top plate 1 in the lateral direction. According to this, even if the subject stretches his or her legs forward during the examination, the support 30 is present between the left and right legs, and the subject's feet and the support 30 come into contact with each other. can reduce the possibility.

<Leg>
The legs 4 are provided to support the pillars 30 on the floor. For example, the leg 4 is an H-shaped member. For example, in this embodiment the leg 4 comprises a connecting member 4a, a grounding member 4b, and a grounding member 4c.

The connecting member 4a is a long plate-shaped member that connects the grounding members 4b and 4c. For example, the connection member 4a extends in the lateral direction of the top plate 1. As shown in FIG. In this embodiment, one end of the connection member 4a is connected to the grounding member 4b, and the other end is connected to the grounding member 4c. Further, in this embodiment, the connection member 4a and the lower end of the support 30 are connected.

In this embodiment, the connection member 4a and the support 30 are vertically connected. The arrangement of the connection members 4a in the z direction is determined based on the arrangement of the struts 30 in the z direction. For example, when the post 30 is located at a distance Le from the second end Tb of the top plate 1, the position of the connection member 4a in the z direction is also the distance Le from the second end Tb of the top plate 1. are separated by According to this, when the subject puts his or her foot under the top plate 1 (that is, under the switch mechanism 20) during the examination, the connecting member 4a and the subject's foot come into contact with each other. can be suppressed. Moreover, in the case of a subject using a wheelchair, it is possible to prevent the caster (front wheel) of the wheelchair from contacting the connection member 4a and interfering with the examination.

For example, the grounding members 4b and 4c extend in the longitudinal direction of the top plate 1 (z direction, see FIG. 2). For example, the distance between the grounding member 4b and the grounding member 4c is designed to be shorter than the width of casters (front wheels) of a general wheelchair. For example, the distance between the ground members 4b and 4c is determined such that the ground members 4b and 4c are positioned inside the casters of the wheelchair during inspection. Therefore, when an examinee using a wheelchair approaches the tabletop 1 by moving in a direction parallel to the z direction for examination, the casters (front wheels) of the wheelchair and the ground contact members 4b and 4c are in contact with each other. Contact is reduced.

For example, the legs 4 are arranged to fit under the top plate 1 . In other words, the legs 4 are arranged so that the legs 4 do not protrude outside the top plate 1 when the electric optical table 10 is viewed from directly above. For example, the length of the grounding members 4b and 4c in the x direction is equal to or less than the length of the top plate 1 in the x direction. For example, the length of the connection member 4a in the z direction is equal to or less than the length of the top plate 1 in the z direction. According to this, the area required for installing the legs 4 does not become larger than the area of the top plate 1, so an increase in the installation area of the electric optical table 10 can be suppressed.

It should be noted that the arrangement and shape of the leg portion 4 in this embodiment are merely an example, and the present invention is not limited to this (see [Modified Example] below).

The height h of the legs 4 from the floor (the height from the floor to the upper surface) is formed to be lower than the height position of the footrest FR provided on the wheelchair. For example, in this embodiment, the height h of the legs 4 is set to 50 mm or less based on the specifications of general wheelchairs. As a result, when a subject using a wheelchair approaches the electric optical table 10, contact between the footrest FR of the wheelchair and the legs 4 is avoided, so the subject can easily approach the examination apparatus 100. become.

In this embodiment, the height h of the entire leg 4 is lower than the height of the footrest FR. More specifically, it should be lower than the height of the post of the footrest FR (not shown).

<Lever>
The structure of the lever 5 for adjusting the height of the top plate 1 will be described with reference to FIG. For example, by operating the lever 5, the examiner can switch between the first drive mode and the second drive mode for operating the top plate 1. FIG. For example, the first drive mode is a mode in which the tabletop 1 is automatically moved to a predetermined set position (for example, upper limit position or lower limit position). For example, the second drive mode is a mode in which the table 1 is manually moved to a position desired by the examiner.

For example, which of the first drive mode and the second drive mode the tabletop 1 should be operated in is determined by the operation amount of the lever 5 . For example, the lever 5 is held at the center of the movable range (hereinafter simply referred to as "movable center") by a holding mechanism (not shown) such as a spring when not operated by the examiner. For example, the movable range of the lever 5 is set with a threshold value for causing the controller 70 to selectively execute either the first drive mode or the second drive mode. For example, when the lever 5 is operated with an operation amount equal to or greater than a threshold from the movable center (for example, an operation amount when moving the lever 5 to the maximum movable range), an operation for operating the top plate 1 in the first drive mode. A signal (first operation signal) is output. For example, when the lever 5 is operated by an operation amount less than the threshold from the movable center, an operation signal (second operation signal) for operating the table top 1 in the second drive mode is output. Details of the first operation signal and the second operation signal will be described later.

<Vertical movement mechanism>
FIG. 6 shows the internal configuration of the vertical movement mechanism 31 of the electric optical table 10. As shown in FIG. The post 30 is composed of a slide portion 30a for vertically moving the top plate 1, a base portion 30b for supporting the slide portion 30a, and a vertical movement mechanism 31 for vertically sliding the slide portion 30a along the base portion 30b. be. A gear 33a is attached to the rotary shaft of the motor 32 attached to the slide portion 30a, and a gear 33b provided on a feed screw 34 is meshed with the gear 33a. A nut portion 35 for the feed screw 34 is attached to the base portion 30b side. The rotation of the motor 32 causes the feed screw 34 to rotate, thereby moving the slide portion 30a up and down.

Regarding the vertical movement mechanism 31, a configuration for detecting the vertical movement range of the slide portion 30a will be described with reference to FIGS. 6 and 7. FIG. FIG. 7 is a diagram illustrating the configuration of the sensors 36a and 36b. A sensor 36a and a sensor 36b are provided on the base portion 30b to detect the upper and lower limits of the vertical movement range of the slide portion 30a. For example, the sensor 36a is a photoelectric sensor and is composed of a set of a light projecting portion and a light receiving portion (see FIG. 7A). Infrared light is projected from the light projecting section to the light receiving section. The same applies to the sensor 36b. A convex portion B passing between the light projecting portion and the light receiving portion of the sensor is provided at the lower end of the slide portion 30a. When the sliding portion 30a is moved and the convex portion B blocks the infrared light from the light projecting portion of the sensor 36a, the rotation of the motor 32 is controlled to stop (see FIG. 7B). For example, similar control is performed for the sensor 36b. Thereby, the vertical movable range of the slide portion 30a is detected. The vertical movement mechanism 31 is controlled based on an operation signal from the lever 5 and an input signal from the microswitch 22. As shown in FIG.

<Switch Mechanism>
FIG. 8 is an explanatory diagram of the internal configuration of the switch mechanism 20. As shown in FIG. The switch mechanism 20 includes a cover 21 attached to the back surface of the top plate 1 with a predetermined gap therebetween, a microswitch 22 for stopping the downward movement of a vertical movement mechanism 31, which will be described later, and the cover 21 and the top plate 1. and a pressing portion 24 attached inside the cover 21 for driving the microswitch 22 . The microswitch 22 is attached to the back surface of the top plate 1, and the switch signal is transmitted to the control section 70, which will be described later. The control unit 70 stops the downward movement of the vertical movement mechanism 31 based on the switch signal. Also, the cover 21 is preferably formed as thin as possible. As a result, the movable range of the top plate 1 can be sufficiently secured.

Further, in this embodiment, the switch mechanism 20 is provided so as to cover a predetermined range (a range up to the extent that the subject's knees enter) from the end surface of the tabletop 1 on the side where the subject is located. ing. With such a configuration, even if the top board is lowered while the subject faces the electric optical table 10 and the subject's arms or knees come into contact with the top board 1, the cover is immediately covered. 21 comes into contact with the arm (or foot), the cover 21 is pushed upward (in the direction toward the back surface of the top plate 1), the pressing portion 24 presses the microswitch 22, and the driving of the top plate 1 is stopped. be done. As a result, the subject's arms, knees, or the like are prevented from being erroneously pressed strongly by the tabletop 1 .

<Control unit>
FIG. 9 is a control block diagram of the electric optical table 10 in this embodiment. For example, the control unit 70 is configured to control the driving of the pillars 30 and adjust the height position of the tabletop 1 . For example, the lever 5 , the power switch 8 , the microswitch 22 of the switch mechanism 20 , and the vertical movement mechanism 31 are connected to the controller 70 . For example, the control unit 70 adjusts the height position of the table top 1 based on the first operation signal and the second operation signal input by operating the lever 5 . The details of the adjustment method will be described later in [Operation]. Note that, for example, the control unit 70 performs the adjustment based on the sensors 36a and 36b of the vertical movement mechanism 31 when adjusting the height of the tabletop 1 to the set position described later. Of course, in order to adjust the height of the tabletop 1, detection means such as an encoder may be provided. In that case, the control unit 70 may adjust the height of the table top 1 based on the detection result of the detection means.

[motion]
Next, a specific example will be used to describe the operation of placing a subject in a wheelchair on the electric optical table 10 having the configuration described above and positioning the subject for examination.

The examiner operates the lever 5 to adjust the height of the top plate 1 of the electric optical table 10 on which the inspection apparatus 100 is placed so as not to hit the knees of the examinee. In this embodiment, the examiner moves the tabletop 1 in the first drive mode to roughly adjust its height, and then moves the tabletop 1 in the second mode to adjust its height. A case of finely adjusting is given as an example. In this embodiment, before the height of the tabletop 1 is adjusted, the tabletop 1 is positioned at the lower limit of the movable range (movement range).

<First drive mode>
Operation of the lever 5 and movement of the top plate 1 in the first drive mode in this embodiment will be described with reference to FIG. For example, the examiner operates the lever 5 held at the movable center and pushes the lever 5 up to the upper limit of the movable range (see FIG. 10(a)). As a result, the operation amount of the lever 5 exceeds the threshold value, and an operation signal (first operation signal) for applying the first drive mode and moving the tabletop 1 is input. Here, by pulling up the lever 5 , a first operation signal for moving the table top 1 to the upper limit position is input to the control section 70 . When the examiner releases the lever 5, the lever 5 returns to the movable center position. keep moving.

For example, the sensor 36a provided in the vertical movement mechanism 31 detects that the tabletop 1 has reached the upper limit of the movement range. The control unit 70 stops moving the tabletop 1 when the detection signal from the sensor 36b is input. Thereby, the top plate 1 is arranged at the upper limit position (see FIG. 10(b)).

A similar consideration can be given to the case where the examiner pushes down the lever 5 to the lower limit of the movable range and moves the top plate 1 to the lower limit position in the first drive mode. At this time, the sensor 36b detects that the top plate 1 has reached the lower limit of the movement range, and the movement of the top plate 1 is stopped based on the detection signal from the sensor 36b, so that the top plate 1 reaches the lower limit position. placed.

For example, in the first drive mode, even if the examiner finishes operating the lever 5 (even if the examiner releases his/her hand from the lever 5), the top plate 1 continues to move. is shorter than the time to move the table top 1. According to this, while the tabletop 1 is being moved to the upper limit position or the lower limit position, the examiner can perform other work such as assisting the examinee or organizing medical charts.

In the first drive mode described above, the examiner moves the top plate 1 to the upper or lower limit of the movement range while performing other work, and roughly adjusts the height of the top plate 1 according to the height of the examinee. can be adjusted to

Next, the examiner moves the wheelchair to the second end Tb side of the tabletop 1 in order to align the examinee and the examination apparatus 100 . As described above, in this embodiment, the support 30 and the connection member 4a of the leg 4 are separated from the second end Tb by the distance Le. Therefore, when the subject places his/her feet under the top plate 1, contact between the subject's feet and the struts 30 and the connecting members 4a is suppressed. Furthermore, contact between the armrests AR and the top plate 1 is avoided because the width d of the top plate 1 in the lateral direction is shorter than the length between the left and right armrests AR of the wheelchair. These allow the subject to easily approach the inspection apparatus 100 .

<Second drive mode>
Next, the examiner lowers the tabletop 1 from the upper limit position in the second drive mode and finely adjusts the height of the tabletop 1 . Operation of the lever 5 and movement of the top plate 1 in the second drive mode in this embodiment will be described with reference to FIG. For example, the examiner pushes down the lever 5 held at the movable center with an operation amount that does not exceed the threshold value (see FIG. 11A). While the lever 5 continues to be pushed down by an operation amount that does not exceed the threshold value, an operation signal (second operation signal) for applying the second drive mode to move the tabletop 1 is sent from the lever 5 to the control unit 70. is entered in The control unit 70 continues to lower the tabletop 1 while the second operation signal is being input. For example, when the examiner stops operating the lever 5 (releases his/her hand from the lever 5), the lever 5 returns to the movable center position, and the input of the second operation signal is stopped. In this case, the control unit 70 stops the lowering of the tabletop 1 (see FIG. 11(b)).

By the above operation, the examiner can lower the top plate 1 by continuing to push down the lever 5 and then release the lever 5 to place the top plate 1 at the desired height. The case where the examiner continues to push up the lever 5 to raise the top plate 1 to the desired height can be similarly considered.

With the second driving mode described above, the examiner can move the tabletop 1 to the desired height position, so that the height of the tabletop 1 can be finely adjusted according to the height of the examinee. .

As described above for the configuration and operation, for example, in the motorized optical table 10 of this embodiment, the post 30 is arranged below the inspection apparatus 100 with the top plate 1 interposed therebetween. Thereby, the installation area of the electric optical table 10 can be suppressed and arranged. In the present embodiment, by arranging the post 30 on the side of the first end Ta of the top plate 1, the space between the detection means provided on the side of the second end Tb of the top plate 1 and the floor surface is detected. is formed, the feet of the subject and the casters (front wheels) of the wheelchair can be arranged on the lower part of the top plate 1, and the examination can be performed in a comfortable posture for the subject.

Further, in this embodiment, by arranging the legs 4 so as to be accommodated in the lower portion of the top plate 1, it is possible to suppress an increase in the installation area of the electric optical table 10. FIG. More specifically, by arranging the connecting member 4a, the grounding member 4b, and the grounding member 4c so as to be accommodated in the lower portion of the top plate, an increase in the installation area of the electric optical bench 10 can be suppressed. In addition, by arranging the legs 4 so as to be accommodated in the lower part of the top plate 1, when arranging the electric optical table 10, the back and side surfaces of the inspection apparatus 100 can be brought closer to the wall surface.

[Transformation example]
In this embodiment, a case has been described in which the post 30 is arranged near the center from the first end Ta of the top plate 1, but the present invention is not limited to this. The struts should be arranged at a distance in the Z direction from the subject side (that is, the second end Tb side) such that the feet of the subject and the casters (front wheels) of the wheelchair do not come into contact with the struts 30. good. For example, the pillars 30 may be arranged on the edge of the top plate 1 .

In the present embodiment, the case where there is one strut 30 has been described, but the number of struts 30 is not limited to this. For example, the number of struts 30 may be plural. Even in that case, each support 30 may be arranged with respect to the top plate 1 at a distance Le from the second end Tb, which is on the side of the subject during the examination. According to this, as in the case where there is only one support 30, contact between the support 30 and the subject's foot during the examination is reduced.

In this embodiment, the configuration in which the support pillar 30 is arranged on the central axis C in the lateral direction (the x direction in FIG. 4) of the top plate 1 is taken as an example, but the present invention is not limited to this. For example, the struts 30 may be arranged at positions closer to either end of the tabletop 1 in the lateral direction (horizontal direction as viewed from the subject side).

In this embodiment, the case where the shape of the leg portion 4 is H-shaped has been described, but the shape of the leg portion 4 is not limited to this. For example, the shape of the leg portion 4 may be any shape that takes into consideration that the casters (front wheels) of the wheelchair do not come into contact with the leg portion 4 during inspection. An example of a modified shape of the leg portion 4 will be described below with reference to FIG. 12 . Of course, various shapes different from these modified examples can be applied to the leg portion 4 .

For example, the shape of the legs 4 may be cross-shaped as shown in FIG. 12(a). In this case, the grounding member 4b extending in the longitudinal direction of the top plate 1 is sufficient, and the grounding member 4c can be omitted. During the examination, the left front wheel of the wheelchair is placed on the left side of the ground contact member 4b, and the right front wheel of the wheelchair is placed on the right side of the ground contact member 4b. is suppressed.

Further, for example, the shape of the leg portion 4 may be U-shaped as shown in FIG. 12(b). In this case, grounding members 4b and 4c extending in the longitudinal direction of top plate 1 may be connected by arc-shaped connecting member 4a. During the inspection, the casters (front wheels) of the wheelchair are positioned on the side of the U-shaped opening and outside the grounding members 4b and 4c. It is also possible to position the left and right casters on the inside of the grounding member 4b and the outside of the grounding member 4c, or on the outside of the grounding member 4b and the inside of the grounding member 4c. This suppresses contact between the legs 4 and the subject's feet.

Further, for example, the shape of the leg portion 4 may be V-shaped as shown in FIG. 12(c). In this case, in the leg portion 4, the grounding member 4b and the grounding member 4b extending obliquely in the longitudinal direction of the top plate 1 and the grounding member 4c extending symmetrically in the widthwise direction of the top plate 1 are connected. It may be configured by It is also possible to omit the connection member 4a. During the examination, the casters (front wheels) of the wheelchair are positioned outside the grounding members 4b and 4c, so contact between the legs 4 and the subject's feet is suppressed.

In this embodiment, one lever 5 is used as the first operating means for inputting the first operating signal in the first driving mode and as the second operating means for inputting the second operating signal in the second driving mode. Although the case of sharing is explained, it is not limited to this. For example, the first operating means and the second operating means may be provided separately. For example, in this case, two levers, a lever for inputting the first operation signal and a lever for inputting the second operation signal, may be provided.

Although the lever 5 is used as the operation means for changing the height position of the tabletop 1 in this embodiment, the operation means is not limited to this. For example, the operating means may be a switch. For example, the operating means may be a foot pedal. For example, the operating means may be a handle. Of course, these operation means are examples and are not limited.

In the present embodiment, a configuration has been described in which the table top 1 automatically moves to the upper limit or lower limit of the movement range in the first drive mode, but the present invention is not limited to this. In the first drive mode, the tabletop 1 does not necessarily have to be configured to move to the upper limit position and the lower limit position of the movement range, and positions different from these positions may be set in advance as set positions.

In addition to the upper limit position and the lower limit position, the top plate 1 may be movable to an intermediate position between the upper limit position and the lower limit position. In other words, the set positions of the tabletop 1 in the first drive mode may be set in advance to the upper limit position, intermediate position, and lower limit position. A plurality of intermediate positions may be provided.

For example, when the movement of the tabletop 1 in the height direction is stopped at an intermediate position, the vertical movement mechanism 31 may be provided with a sensor for detecting that the tabletop 1 has moved to the intermediate position. good. The configuration of such sensors may be similar to sensors 36a, 36b. As a result, even when the table top 1 is roughly moved according to the height of the subject, it is easy to adjust the height position to an appropriate one for each subject. Even in the subsequent fine movement of the tabletop 1 in the second drive mode, the tabletop 1 can be adjusted efficiently because the height position of the tabletop 1 is roughly appropriate in the first drive mode. It should be noted that the greater the number of set positions to which the top plate 1 can be moved, the more finely the examiner can automatically adjust the top plate 1 to a finer position in the first drive mode.

In addition, when the intermediate position is provided as the set position of the top plate 1, any set position to which the top plate 1 can be moved may be selected according to the operation of the operating means by the examiner. For example, when the examiner raises the lever 5 to the upper limit of the movable range a plurality of times in succession, the controller 70 moves the top board 1 from the current position to the set position in the upward direction by the number of times the lever 5 is pushed up. You can move it. Specifically, for example, when the lever 5 is pushed up to the upper limit of the movable range twice in succession, the control unit 70 may raise the table top 1 to a set position two steps higher than the current position. . Of course, the case where the examiner pushes down the lever 5 to lower the top plate 1 can also be considered in the same way. Further, when the intermediate position is provided as the setting position of the top plate 1, switches corresponding to the upper limit position, each intermediate position, and the lower limit position may be provided. For example, the examiner may operate a switch corresponding to the set position of the table 1 to select an arbitrary setting position to which the table 1 is to be moved.

In this embodiment, first, the first driving mode is used to roughly adjust the position of the tabletop 1, and then the second driving mode is used to finely adjust the position of the tabletop 1. was described as an example, but it is not limited to this. The examiner can adjust the height position of the tabletop 1 using only one of the first drive mode and the second drive mode. Of course, it is also possible to adjust the height position of the top plate 1 by applying any combination of the first driving mode and the second driving mode.

The examiner may stop the movement of the table 1 and finely adjust the height of the table 1 before the table 1 reaches the set position in the first drive mode. Therefore, when the lever 5 is operated again to input the second operation signal while the tabletop 1 is being moved according to the first operation signal from the lever 5, the control unit 70 outputs the first operation signal. may be stopped and switched to movement by the second operation signal. According to this, the examiner appropriately stops the movement of the tabletop 1 in the first drive mode at the timing when the subject has an approximate height, and then adjusts the position of the tabletop 1 in the second drive mode. Can be fine-tuned. Therefore, for example, even if the top plate 1 is configured to automatically move to the upper limit position and the lower limit position of the movement range, the top plate 1 can be arranged at any position between the upper limit position and the lower limit position. The height of the electric optical table can be adjusted efficiently.

In the present embodiment, the sensors 36a and 36b have been described as an example of the configuration for the control unit 70 to detect the position of the tabletop 1, but the configuration is not limited to this. For example, a magnetic sensor may be used to detect the position of the tabletop 1 . Further, for example, a microswitch may be provided as a configuration for detecting the position of the tabletop 1 . Furthermore, for example, the position of the table top 1 may be detected according to the rotation speed of the motor 32 .
