Description

  The present invention relates to an attachment position recognition mechanism for a console of a medical device, and more particularly to an attachment position recognition mechanism for a console that is used by changing the attachment position as necessary.

  It has a top plate on which the subject is placed and a movable unit driven by the drive unit. A console is attached around the top plate, and the movable unit is driven by operating the operation unit provided on the console. In a medical device that performs a treatment action on a subject, the attachment position of the console may be changed as necessary. The console mounting positions to be changed are “the right side of the subject”, “the left side of the subject”, “the foot side of the subject”, and “the head side of the subject”. When the console is positioned on the “right side of the subject”, “left side of the subject”, or “foot side of the subject”, the console is attached to a rail or the like provided around the top board. Further, when the console is positioned on the “head side of the subject”, the console is attached to a dedicated console mounting base that can be moved, and this console mounting base is moved to the “head side of the subject”.

  When a console whose mounting position can be changed is attached to the "right side of the subject" and "left side of the subject", even if the console operation unit is operated in the same direction, it is viewed from the operator who operates the console. The moving direction of the movable part is the left-right reverse direction or the front-rear reverse direction. If this state is left as it is, the operation direction of the operation unit and the operation direction of the movable unit are opposite to the operator's consciousness, which may cause an erroneous operation.

  Therefore, when the installation position of the console is changed, it is necessary to manually change the setting to match the operation direction of the operation unit provided on the console with the operation direction of the movable unit viewed from the operator who operates the console. Is going on.

  However, this manual setting change is troublesome and time consuming. In addition, there is a case where the setting change is forgotten or the setting change is wrong. In such a case, when the operator operates the console operation unit to drive the movable unit, the operator can move in an unintended direction. The situation that the part operates will occur.

  Therefore, as described in Patent Document 1, in order to eliminate the complexity of manual setting changes when changing the console mounting position, and to prevent setting changes from being forgotten or mistaken for setting changes, There has been known an invention in which setting change can be automatically performed when the installation position of the console is changed.

  According to the invention described in Patent Document 1, when the console (operation panel) is attached to the guide rail of the top plate, between the transmitter provided on the console and the receiver provided on the guide rail side. Signals are transmitted and received. A plurality of receiving units are arranged around the top plate, and the console mounting position is recognized by detecting which receiving unit has transmitted and received signals.

When the installation position of the console is recognized, the operation direction of the movable part when the console operation unit is operated is controlled by the control circuit according to the recognized installation position.

  However, in the invention described in Patent Document 1, the following points are not considered.

  Because the console installation position is recognized by transmitting and receiving signals between the transmitter provided on the console and the receiver provided on the guide rail side, multiple receptions are possible depending on the console installation position. It is necessary to provide a portion, and the number of parts increases and the structure becomes complicated.

  Also, in the case of a structure in which the transmitter and the receiver are spaced apart and communicate with each other by infrared rays or the like, if dust or the like enters between the transmitter and the receiver, transmission and reception are hindered. It may become impossible to recognize the mounting position.

  The present invention has been made to solve such a problem, and the object of the present invention is to provide a console that can reliably recognize the changed console mounting position with a simple structure when the console mounting position is changed.
