Description

Ultrasonic diagnostic apparatus

Technical Field

The present invention relates to an ultrasonic diagnostic apparatus, and more particularly to a technique for improving operability of a probe cable.

Background

The ultrasonic diagnostic apparatus includes an apparatus main body and an ultrasonic probe that transmits and receives ultrasonic waves. When the ultrasonic probe is connected to the apparatus main body by a wire, a probe-side connector to which a probe cable extending from a probe head (a portion that transmits and receives ultrasonic waves) of the ultrasonic probe is connected to a main-body-side connector provided in the apparatus main body. Generally, more than a hundred signal lines are inserted into a probe cable, and the weight of the cable is much heavier than that of a normal cable.

Since it is assumed that the ultrasonic diagnostic apparatus is used in various situations and various parts of the subject need to be diagnosed, the probe needs to be movable to a position that is apart from the apparatus main body to some extent. Therefore, the probe cable needs to have a certain length. On the other hand, in recent years, it is recommended from a hygienic viewpoint not to bring the probe cable into contact with the skin or floor of a user such as a doctor or a nurse or a subject.

Therefore, nowadays, it is proposed to provide a means for hooking the probe cable in the apparatus main body. For example, patent document 1 discloses that a clamping member for elastically holding a probe cable is provided in an apparatus main body. Further, patent document 2 discloses that a hook member for hooking the probe cable is provided below the probe holder.

Problems to be solved by the invention

When the hook member is provided below the probe holder, it is difficult for a user who is facing the ultrasonic diagnostic apparatus to visually confirm the hook member, and it is difficult to hook the probe cable to the hook member. Therefore, in order to allow the user to hook the probe cable while observing and checking the hook member, it is conceivable to dispose the hook member at a position protruding from the end of the apparatus main body in the horizontal direction.

On the other hand, if the hook member is disposed at a position protruding from the end of the apparatus main body in the horizontal direction, the width of the ultrasonic diagnostic apparatus increases accordingly. The ultrasonic diagnostic apparatus may be used in a narrow place or may be carried through a narrow passage, and the hook member may be an obstacle.

The invention aims to provide an ultrasonic diagnostic apparatus with a hook member, wherein the hook member is used for hooking a probe cable and can change the posture according to the use environment of the ultrasonic diagnostic apparatus.

Means for solving the problems

An ultrasonic diagnostic apparatus according to the present invention is characterized by comprising: an ultrasonic probe having a probe head for transmitting and receiving ultrasonic waves and a probe cable for connecting the probe head and an apparatus main body; a probe holder which holds the probe; a hook member disposed close to the probe holder and having a hooking portion for hooking the probe cable; and a hook support mechanism that supports the hook member so as to be capable of changing a posture between a hanging posture in which the hook member does not protrude from an end portion of the apparatus main body in a horizontal direction and an erected posture in which the hook portion protrudes from the end portion of the apparatus main body in the horizontal direction and the hook portion is positioned above the hanging posture.

According to the above configuration, the hook member for hooking the probe cable changes its posture between the hanging posture and the standing posture. In the hanging posture, the hook member does not protrude from the end of the apparatus main body in the horizontal direction, that is, the width of the apparatus main body does not become large, and the hook member can hook the probe cable without being an obstacle even in a narrow space. Further, the hook member does not become an obstacle even when the ultrasonic diagnostic apparatus passes through a narrow passage. When the ultrasonic diagnostic apparatus is used in a relatively large space, the hook member can be set in an upright posture. In the standing posture, the hooking portion protrudes from an end portion of the apparatus main body in a horizontal direction. Thus, the user facing the apparatus main body can observe and confirm the hooking part, and can properly hook the probe cable. In the standing posture, the hooking portion is located above the hanging posture, and therefore, the user can easily hook the probe cable.

Preferably, the hook support mechanism supports the hook member so as to be rotatable in a vertical plane, and the hook member changes its posture between the hanging posture and the standing posture by a rotational motion.

Preferably, the hooking portion includes: the rod part is used for hooking the probe cable; and a side wall provided at an end of the rod portion and substantially orthogonal to an extending direction of the rod portion, the side wall having the following shape: the hook member extends upward from the stem portion when the hook member is in the hanging posture, and extends upward from the stem portion when the hook member is in the standing posture.

According to this configuration, the side wall extends upward relative to the rod regardless of whether the hook member is in the hanging position or the standing position. Therefore, the side wall prevents the probe cable from falling off from the hooking part regardless of the posture of the hook member, i.e., the hanging posture or the standing posture.

Preferably, the probe holders are provided in plurality, the hooking portions are provided in plurality corresponding to the probe holders, respectively, and the arrangement direction of the probe holders coincides with the arrangement direction of the hooking portions.

According to this configuration, even when the plurality of probes are held by the plurality of probe holders, the plurality of probe cables extending from the plurality of probes are hooked on the respective hooking portions, and therefore, the possibility of the plurality of probe cables being entangled is reduced.

Preferably, the hook member further comprises a locking mechanism for fixing the posture of the hook member to either the hanging posture or the standing posture.

According to this configuration, the probe cable can be hooked with the hook member fixed in the hanging posture or the standing posture.

The effects of the invention are as follows.

According to the present invention, it is possible to provide an ultrasonic diagnostic apparatus including a hook member for hooking a probe cable and capable of changing its posture according to the use environment of the ultrasonic diagnostic apparatus.

Detailed Description

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

Fig. 1 is a perspective view of an ultrasonic diagnostic apparatus 10 according to the present embodiment. The ultrasonic diagnostic apparatus 10 is used in the medical field, and is an apparatus including: an ultrasound image is formed based on reception signals acquired by transmitting and receiving ultrasound waves to and from a subject (particularly, a human body). In fig. 1, the lateral direction of the ultrasonic diagnostic apparatus 10 is defined as the X axis, the depth direction (front-back direction) is defined as the Y axis, and the height direction (up-down direction) is defined as the Z axis. The ultrasonic diagnostic apparatus 10 includes an apparatus main body 12 and one or more probes 14 connected to the apparatus main body 12.

The apparatus main body 12 includes a base unit 16, a monitor 18 for displaying an ultrasonic image, an operation unit including various switches, a trackball, and the like, an operation panel 20 including a second monitor, and a plurality of probe holders 22 disposed on both left and right sides of the operation panel 20.

The probe 14 includes a probe head 24 that transmits and receives ultrasonic waves, and a probe cable 26 that extends from the probe head 24 toward the apparatus body 12.

A plurality of electronic circuit boards and a power supply unit are housed in the base unit 16. Although not shown in fig. 1, one or more body-side connectors are provided on the front side surface of the base unit 16. The probe-side connector to which the probe cable 26 is connected to the main body-side connector. Thereby, the probe 14 is connected to the apparatus main body 12 (base unit 16). In addition, hundreds or more signal lines are inserted into the probe cable 26.

The operation panel 20 is coupled to the base unit 16 so as to be movable up and down and slidable in the front-rear direction. Alternatively, the rotation can be performed in a horizontal plane. The plurality of probe holders 22 are coupled to each other by a holder base 28, and the holder base 28 is integrated with the operation panel 20. That is, the plurality of probe holders 22 are moved in accordance with the movement of the operation panel 20.

Fig. 2 is an enlarged perspective view of the plurality of probe holders 22 provided on the right side of the operation panel 20. In the present embodiment, three probe holders 22 are provided on each of the left and right sides of the operation panel 20. That is, there are six probe holders 22 in total.

The probe holder 22 has a concave shape, and the probe 24 is held by the probe holder 22 by inserting the probe 24 into the probe holder 22 with its distal end (ultrasound transmitting/receiving surface side) facing upward. A through hole is provided in the bottom surface of the probe holder 22, and a probe cable 26 extending from the held probe 24 extends downward from the through hole. A slit for passing the probe cable 26 is provided on a side surface of each probe holder 22. The slit communicates with the through hole.

The cable hook 30 as a hook member is used to hook the probe cable 26 extending from the probe head 24 held by the probe holder 22 or the probe cable 26 extending from the probe head 24 taken out from the probe holder 22 in use. The cable hook 30 has a hooking portion where the probe cable 26 is hooked. In the present embodiment, the cable hook 30 has a substantially T-shape, and two hooking grooves 34 are formed in one cable hook 30. The hooking groove 34 forms a hooking portion. The cable hook 30 is disposed close to the probe holder 22 so that one hook groove 34 corresponds to one probe holder 22. In the present embodiment, three probe holders 22 are provided on each of the left and right sides of the operation panel 20, and two hooking grooves 34 are formed in one cable hook 30, so that two cable hooks 30 are provided near the three probe holders 22 on the right side, and two cable hooks 30 are similarly provided near the three probe holders 22 on the left side.

Specifically, the hooking groove 34a of the cable hook 30 formed on the proximal side shown in fig. 2 corresponds to the probe holder 22a, and the probe cable 26 extending from the probe 24 (predetermined to be held by the probe holder 22 a) corresponding to the probe holder 22a is hooked to the hooking groove 34 a. Similarly, the hooking groove 34b corresponds to the probe holder 22 b. Similarly, the hooking groove 34c of the cable hook 30 formed on the back side corresponds to the probe holder 22 c. In the present embodiment, the probe holder 22 corresponding to the hooking groove 34d of the cable hook 30 on the back side is not present, but in the case where four probe holders 22 are provided on one side of the probe holder 22, the hooking groove 34d can correspond to the fourth probe holder 22.

The cable hook 30 is supported on a hook base 32 mounted to the device body 12. That is, the hook base 32 functions as a hook support mechanism. In the present embodiment, the hook base 32 is attached to the lower portion (lower surface) of the holder base 28. In the present embodiment, a plurality of hook bases 32 are provided corresponding to the plurality of cable hooks 30.

FIG. 3 is a front view of the probe carrier 22, cable hook 30, and hook base 32. In fig. 3, a part of the probe holder 22a (a part protruding downward from the lower surface of the holder base 28) is not shown for convenience of explanation. As shown in fig. 3, the hook base 32 supports the cable hook 30 to be rotatable in an XZ plane (vertical plane). Specifically, the cable hook 30 is rotatable about a horizontal axis 36 parallel to the Y axis. For example, a circular hole is formed in one of the cable hook 30 and the hook base 32, and the cable hook 30 can rotate in the XZ plane by inserting a horizontal shaft formed in the other into the hole and coupling the two.

The cable hook 30 changes the posture of the cable hook 30 by rotating. In the present embodiment, the posture can be changed between a hanging posture (posture shown in fig. 3 as 30A) in which the base shaft portion 40 (a shaft extending in one direction from a joint with the hook base 32) of the cable hook 30 is substantially perpendicular and the distal end of the base shaft portion 40 (an end opposite to the hook base 32) is positioned downward, and a standing posture (posture shown in fig. 3 as 30B) in which the base shaft portion 40 is rotated so as to be raised from the hanging posture and becomes substantially horizontal. In the present embodiment, the cable hook 30 is fixed in the hanging posture or the standing posture by a lock mechanism described later. The posture of the cable hook 30 is changed by the user.

When the cable hook 30 is in the hanging posture, the entire cable hook 30 is housed inside the end portion of the apparatus main body 12 (the center side of the apparatus main body 12). That is, in the hanging posture, the cable hook 30 does not protrude from the end portion of the apparatus main body 12 in the horizontal direction. In the present embodiment, since the side end of the apparatus main body 12 is the side end of the holder base 28, when the cable hooks 30 are in the hanging posture, all the cable hooks 30 are accommodated inside a vertical line 38 passing through the side end of the holder base 28.

On the other hand, when the cable hook 30 is in the standing posture, the hooking groove 34 provided in the cable hook 30 moves upward from the hanging posture, and the hooking groove 34 protrudes outward in the horizontal direction from the vertical line 38. This allows the user facing the operation panel 20 to visually confirm the hooking groove 34.

Hereinafter, the cable hook 30 will be described in detail. First, the cable hook 30 in the upright posture will be described with reference to fig. 4 and 5. Fig. 4 is a perspective view showing the cable hook 30 and the hook base 32 in the standing posture. Fig. 5 is a side view of the cable hook 30 and the hook base 32 in the standing posture.

As described above, the cable hook 30 has a substantially T-shape. Specifically, the cable hook 30 includes: a base shaft portion 40 extending in one direction from a point of engagement with the hook base 32; a horizontal rod 42 projecting from a distal end of the base shaft portion 40 in the horizontal direction; a guide wall 44 provided at one end side of the horizontal bar 42; and a guide wall 46 provided on the other end side of the horizontal bar 42.

The base shaft portion 40 has a shape extending upward from the horizontal rod 42 when the cable hook 30 is in the standing posture. That is, the extension 40a extends upward from the horizontal rod 42. Similarly, the guide wall 44 has an extending portion 44a extending upward from the horizontal bar 42 even when the cable hook 30 is in the standing posture. The guide wall 46 also has an extending portion 46a that extends upward from the horizontal rod 42 when the cable hook 30 is in the standing posture.

The horizontal bar 42 (the proximal portion thereof), the base shaft portion 40, and the guide wall 44 form a first hooking groove 34 a. The horizontal bar 42 forms a bar portion of the hooking groove 34a as a hooking portion, and particularly the extended portion 40a of the base shaft portion 40 and particularly the extended portion 44a of the guide wall 44 form a side wall of the hooking groove 34 a. When the probe cable 26 is hooked on the front portion of the horizontal rod 42, the probe cable 26 is prevented from moving toward the rear side (a second hooking groove 34b described later) by the extending portion 40a of the base shaft portion 40. This reduces the possibility that the probe cable 26 is entangled with another probe cable 26 hooked in the second hooking groove 34 b. The extension portion 44a of the guide wall 44 prevents the probe cable 26 from moving forward and falling off the cable hook 30.

Similarly, the horizontal bar 42 (the inner portion thereof), the base shaft portion 40, and the guide wall 46 form a second hooking groove 34 b. The horizontal bar 42 forms a bar portion of the hooking groove 34b as a hooking portion, and particularly the extended portion 40a of the base shaft portion 40 and particularly the extended portion 46a of the guide wall 46 form side walls of the hooking groove 34 b. When the probe cable 26 is hooked on the back side portion of the horizontal rod 42, the probe cable 26 is prevented from moving to the front side (the first hooking groove 34a) by the extension portion 40a of the base shaft portion 40. That is, the possibility that the probe cable 26 is entangled with another probe cable 26 hooked in the first hooking groove 34a is reduced. The extension portion 46a of the guide wall 46 prevents the probe cable 26 from moving inward and falling off the cable hook 30.

In the vicinity of the joint position of the base shaft portion 40 and the horizontal bar 42 (distal end of the extended portion 40 a), the extension amount (height) of the extended portion 40a of the base shaft portion 40 is substantially 0, and the height of the extended portion 40a becomes larger as approaching from this position to the proximal side. The height of the extending portion 40a gradually decreases as it approaches the proximal side, with a position shifted from the distal end of the extending portion 40a to the proximal side by a predetermined distance as a boundary. That is, the extending portion 40a has a substantially triangular shape in front view, and an inclined portion 40b is formed on the distal side of the extending portion 40a so as to face upward and rightward (distal side). According to the inclined portion 40b, when the probe cable 26 hooked in the hooking groove 34a is pulled in the inward direction by moving the probe head 24 or moving the probe holder 22 (and the operation panel 20), the probe cable 26 is easily slid in the extending direction at least as compared with a case where the inclined portion 40b is not formed and the extending portion 40a is provided upright at the distal end so as to be perpendicular to the horizontal rod 42. Similarly, when the probe cable 26 hooked in the hooking groove 34b is pulled in the proximal direction, the probe cable 26 is easily slid in the extending direction.

Further, as described above, the extending portion 44a of the guide wall 44 is also substantially triangular in shape in front view, and has the inclined portion 44b directed upward and rightward. The extending portion 46a of the guide wall 46 is also substantially triangular in front view, and has inclined portions 46b that face upward and rightward. According to the

inclined portions

44b and 46b, as described above, when the probe cable 26 hooked in the hooking groove 34 is pulled in the front-rear direction, the probe cable 26 is easily slid in the extending direction.

As described above, according to the inclined portion 40b, the inclined portion 44b, and the inclined portion 46b, when the probe cable 26 hooked in the hooking groove 34 is pulled in the front-rear direction, the possibility of the probe cable 26 being pulled is reduced, and the possibility of causing a failure such as disconnection of the probe cable 26 is reduced. Further, the handling of the probe cable 26 by the user is improved.

From the same viewpoint, it is preferable that the surface of the cable hook 30 is treated to reduce the friction coefficient with the probe cable 26 (to facilitate sliding of the probe cable 26). For example, a lubricating coating treatment or the like is preferably performed.

A lock release switch 50 constituting a part of a lock mechanism described later is provided at the distal end of the base shaft portion 40. The lock release switch 50 is explained in detail below.

Fig. 6 shows a path of the probe cable 26 when the probe cable 26 is hooked in the hooking groove 34 of the cable hook 30 in the standing posture. By hooking the probe cable 26 in the hooking groove 34, the probe cable 26 is prevented from contacting the floor surface. Of course, the length of the probe cable 26 from the probe head 24 to the hooking groove 34 can be appropriately adjusted when the probe cable 26 does not contact the floor surface.

Even when the probe head 24 is taken out of the probe holder 22 and is in use, the hooking of the probe cable 26 to the hooking groove 34 is maintained. This reduces the possibility of the probe cable 26 accidentally coming into contact with the floor surface, the subject, or the skin of the user.

As described above, since the hooking grooves 34 are prepared corresponding to the probe holders 22, even when the plurality of probe heads 24 are held by the plurality of probe holders 22, that is, the plurality of probe heads 24 are prepared and the plurality of probe heads 24 are used instead, the possibility that the plurality of probe cables 26 extending from the plurality of probe heads 24 are entangled is reduced. In particular, since the arrangement direction (the front-rear direction in the present embodiment) of the plurality of probe holders 22 coincides with the arrangement direction of the plurality of hooking grooves 34, the possibility of the plurality of probe cables 26 being entangled is reduced.

As described above, when the cable hook 30 is in the standing posture, the hooking groove 34 protrudes from the end of the apparatus main body 12 in the horizontal direction, and the user can visually confirm the hooking groove 34. This makes it easy for the user to hook the probe cable 26 to the hook groove 34. In the upright posture, the hooking groove 34 moves at least upward from the hanging posture, so that the user can more easily hook the probe cable 26 to the hooking groove 34.

Next, the cable hook 30 in the hanging posture will be described with reference to fig. 7. Fig. 7 shows a perspective view of the cable hook 30 in a hanging posture.

When the cable hook 30 is in the hanging posture, the base shaft portion 40 extends vertically downward from the hook base 32, and therefore extends upward when viewed from the horizontal rod 42. The guide wall 44 has a shape extending upward from the horizontal bar 42 when the cable hook 30 is in the hanging posture. That is, the extension 44c extends upward from the horizontal rod 42. Similarly, the guide wall 46 has an extending portion 46c extending upward from the horizontal bar 42 even when the cable hook 30 is in the hanging posture.

In the hanging posture, the horizontal bar 42 (the proximal portion thereof), the base shaft portion 40, and the guide wall 44 also form the first hooking groove 34 a'. The horizontal bar 42 forms the bar portion of the hooking groove 34a ', and the base shaft portion 40 and particularly the extension portion 44c of the guide wall 44 form the side wall of the hooking groove 34 a'. When the probe cable 26 is hooked on the front portion of the horizontal bar 42, the base shaft portion 40 prevents the probe cable 26 from moving toward the rear (a second hooking groove 34b described later). The extension portion 44c of the guide wall 44 prevents the probe cable 26 from moving forward and falling off the cable hook 30.

Similarly, the horizontal bar 42 (the inner portion thereof), the base shaft portion 40, and the guide wall 46 form a second hooking groove 34 b'. The horizontal bar 42 forms the bar portion of the hooking groove 34b ', and the base shaft portion 40 and particularly the extension portion 46c of the guide wall 46 form the side wall of the hooking groove 34 b'. When the probe cable 26 is hooked on the back side portion of the horizontal bar 42, the proximal end portion 40 prevents the probe cable 26 from moving to the front side (the first hooking groove 34 a'). The extension portion 46c of the guide wall 46 prevents the probe cable 26 from moving inward and falling off the cable hook 30.

Further, as in the case of the standing posture, the inclined portion 40b provided on the base shaft portion 40, the inclined portion 44b provided on the guide wall 44, and the inclined portion 46b provided on the guide wall 46 reduce the possibility that the probe cable 26 hooked on the hooking groove 34 is pulled in the front-rear direction when the probe cable 26 is pulled. Further, the handling of the probe cable 26 by the user is improved.

Fig. 8 shows the path of the probe cable 26 when the probe cable 26 is hooked on the hooking groove 34 of the cable hook 30 in the hanging posture. As in the case where the cable hook 30 is in the standing posture, the probe cable 26 is hooked in the hooking groove 34, thereby preventing the probe cable 26 from coming into contact with the floor surface. In this case, similarly, the length of the probe cable 26 from the probe head 24 to the hooking groove 34 can be appropriately adjusted when the probe cable 26 does not contact the floor surface.

When the probe cable 26 is in a hanging posture, similarly, the arrangement direction (the front-rear direction in the present embodiment) of the plurality of probe holders 22 coincides with the arrangement direction of the plurality of hooking grooves 34, so that the possibility of the plurality of probe cables 26 being entangled is further reduced.

As described above, when the cable hook 30 is in the hanging posture, the entire cable hook 30 is housed inside the end portion of the apparatus main body 12. Thus, even when the ultrasonic diagnostic apparatus 10 needs to be installed in a narrow space, the cable hook 30 does not become an obstacle, and the probe cable 26 can be hooked to the hooking groove 34. When the ultrasonic diagnostic apparatus 10 is passed through a narrow passage, the cable hook is suspended and can pass through the passage.

Hereinafter, a lock mechanism for fixing the cable hook 30 in the standing posture or the hanging posture will be described with reference to fig. 9 and 10.

A cross-sectional view of the cable hook 30 and hook base 32 is shown in fig. 9. The lock release switch 50 provided at the distal end of the base shaft portion 40 of the cable hook 30 communicates with an arm portion 52 inserted through the inside of the base shaft portion 40 and extending to the vicinity of the horizontal shaft 36. A protruding pin 54 protruding in the front-rear direction (Y-axis direction) is provided near the end of the arm portion 52 on the hook base 32 side. The unlock switch 50 and the arm 52 are biased to the remote side (the right side in fig. 9) by an unillustrated elastic member (a coil spring or the like), and are maintained at the positions shown in fig. 9 when the unlock switch 50 is not pushed in by the user. When the lock release switch 50 is pushed toward the near side (left side in fig. 9) by the user, the protruding pin 54 also moves toward the near side.

A partial cross-sectional view of the hook base 32 is shown in fig. 10. A plate (metal plate) 60 standing on the XZ plane is provided inside the hook base 32. The plate 60 is formed with a long hole 62 through which the projecting pin 54 is inserted. The long hole 62 is constituted by a horizontal portion 62a, a vertical portion 62b, and a circular arc portion 62 c.

The horizontal portion 62a is a portion that extends in the horizontal direction (X-axis direction) at the same height as the protruding pin 54 when the cable hook 30 is in the standing posture. The vertical portion 62b is a portion that protrudes in the vertical direction on a vertical line passing through the protruding pin 54 when the cable hook 30 is in the hanging posture. The circular arc portion 62c is a portion connecting the left end portion of the horizontal portion 62a and the upper end portion of the vertical portion 62b, and is a portion having a circular arc shape with the horizontal shaft 36 as the center.

Fig. 10 shows a state in which the cable hook 30 is fixed in the standing posture. In this state, the protruding pin 54 is inserted through the horizontal portion 62 a. Since the projecting pin 54 is biased to the distal side, the projecting pin 54 is located on the right end side of the horizontal portion 62 a. In this state, even if the posture of the cable hook 30 is to be changed, that is, rotated about the horizontal shaft 36, the projecting pin 54 is brought into contact with the upper and lower sides of the horizontal portion 62a, thereby preventing the posture change. That is, the cable hook 30 is fixed in the standing posture.

When the unlock switch 50 is pushed toward the proximal side, the projecting pin 54 moves toward the proximal side and moves toward the left end side of the horizontal portion 62 a. In this state, the protruding pin 54 can move downward by the arc portion 62 c. That is, this state (the state in which the lock release switch 50 is pushed) is the lock release state in which the posture lock of the cable hook 30 is released. When the cable hook 30 is rotated downward by the user, the protrusion pin 54 passes through the circular arc portion 62c and moves to the upper end of the vertical portion 62 b.

When the protrusion pin 54 moves to the upper end of the vertical portion 62b, the protrusion pin 54 moves toward the lower end of the vertical portion 62b by the biasing force applied to the protrusion pin 54. At the same time, the lock release switch 50 also moves to the distal side. In this state, even if the posture of the cable hook 30 is changed, that is, the cable hook is rotated about the horizontal shaft 36, the projecting pin 54 is brought into contact with the right and left sides of the vertical portion 62b, and the change in the posture is prevented. That is, the cable hook 30 is fixed in a hanging posture.

When the lock release switch 50 is pushed in toward the near side again in the hanging posture, the protruding pin 54 moves toward the upper end portion of the vertical portion 60 b. That is, the lock release state is achieved, and the posture can be changed to the standing posture again.

While the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention.

For example, in the present embodiment, the base shaft portion 40 is substantially horizontal in the standing posture and the base shaft portion 40 is substantially vertical in the hanging posture, but in the case where all the cable hooks 30 are located inside the vertical line 38 passing through the end portion of the apparatus main body 12, the hanging posture may not be the posture in which the base shaft portion 40 is substantially vertical. When the hooking groove 34 can be visually confirmed by the user facing the operation panel 20 and the hooking groove 34 is located above the hanging posture, the standing posture may not be the posture in which the base shaft portion 40 is substantially horizontal.
