Ultrasonic diagnosis device
View Patent ↗Disclosed is an ultrasonic diagnosis device which is provided with a shutter mechanism. The shutter mechanism conceals an opening portion (a passage for a rotation shaft member), which is uncovered behind an operation panel when the operation panel moves forward, so as to enhance the appearance and safety. The shutter mechanism has a pair of first shutter plates and a pair of second shutter plates, the pairs overlapping each other. Each shutter plate rotates about a predetermined rotational shaft which does not slide back and forth. Each shutter plate has a pin slot into which a slide pin is inserted. A pair of slide pins are provided on a member that slides back and forth. When the pair of slide pins move forward, the contact relationship between the pair of slide pins and a plurality of pin slots causes the pair of first shutter plates to start closing first, and subsequently the pair of second shutter plates start closing.
1. An ultrasonic diagnosis device, comprising:
an operation panel for ultrasonic diagnosis;
a forward-backward slide mechanism including a forward-backward slide base movable in a forward-backward direction on a rail to guide a slide movement of the operation panel in the forward-backward direction and a slide pin formed on the forward-backward slide base; and
a rotation mechanism having a rotor and a stator, the stator being coupled to the forward-backward slide base, the operation panel being coupled to the rotor for rotational movement,
wherein the forward-backward slide mechanism includes a shutter mechanism that conceals an opening that is exposed when the stator moves forward, the opening being a part of a passage for the movement of the stator in the forward-backward direction,
wherein the shutter mechanism includes:
at least one sheet-like shutter plate that performs a rotation movement about a rotational shaft that does not perform a slide movement in the forward-backward direction; and
a pin slot formed in the shutter plate through which the slide pin is inserted, and
wherein the pin slot has a shape that extends in the forward-backward direction while bending in a lateral direction, and a closing movement force is generated in the shutter plate by a contact relationship between the slide pin and the pin slot when the slide pin moves forward in the pin slot, with the opening being covered by the shutter plate.
2. The ultrasonic diagnosis device according to claim 1 , wherein
the shutter mechanism includes a first shutter plate and a second shutter plate that are in a layered relationship,
a first pin slot formed in the first shutter plate and a second pin slot formed in the second shutter plate have different shapes,
when the slide pin moves forward, a closing movement force is generated in the first shutter plate by a contact relationship between the slide pin and the first pin slot, and also a closing movement force is generated in the second shutter plate by a contact relationship between the slide pin and the second pin slot, and
the opening portion is partially or entirely concealed by cooperation of the first shutter plate and the second shutter plate.
3. The ultrasonic diagnosis device according to claim 2 , wherein
when the slide pin moves forward, the first shutter plate first starts a closing movement, and the second shutter plate subsequently starts a closing movement afterwards, and
a first allocated conceal area that is concealed by the first shutter plate and a second allocated conceal area that is concealed by the second shutter plate partially overlap with each other while being displaced from each other in the forward-backward direction, with the second allocated conceal area being positioned on a forward side with respect to the first allocated conceal area.
4. The ultrasonic diagnosis device according to claim 3 , wherein
a pair of first shutter plates are provided on both sides of a passage of the stator, with the passage being interposed between the pair of first shutter plates; and
a pair of second shutter plates are provided on both sides of the passage of the stator, with the passage being interposed between the second pair of shutter plates;
the pair of first shutter plates performing an open/close movement together and the pair of second shutter plates performing an open/close movement together.
5. The ultrasonic diagnosis device according to claim 4 , wherein
the shutter mechanism further includes:
a pair of sheet-like lower cover plates provided on a lower side of the pair of first shutter plates; and
a pair of sheet-like upper cover plates provided on an upper side of the pair of second shutter plates;
the pair of lower cover plates, the pair of first shutter plates, the pair of second shutter plates, and the pair of upper cover plates constituting a layered structure.
6. The ultrasonic diagnosis device according to claim 5 , wherein
the pair of first shutter plates, the pair of second shutter plates, and the pair of upper cover plates are colored or opaque.
