[0036]
The air flow controller drive unit 64 is electrically connected to a main CPU (not shown), and drives the air flow controller 65 in either the forward direction or the reverse direction under the control of the main CPU. .
[0037]
As shown in FIG. 2, the air flow controller 65 includes an outer cylinder 65a fixed to an end face on either side of the blowing direction of the blower fan 47, and an inner cylinder 65b disposed in the outer cylinder 65a. A main guide pipe 65d disposed to communicate with the outer cylinder 65a, a valve 65c provided at a communication portion between the outer cylinder 65a and the main guide pipe 65d, and a branch 2 at the induction end of the main guide pipe 65d. Two branch guide pipes 65e and 65f are provided.
[0038]
The outer cylinder 65a is formed in a bottomed cylindrical shape, the end face on the blower fan 47 side is opened, and the end face on the main guide pipe 65d side (hereinafter referred to as “outer cylinder rear end face”) is closed. A main guide pipe 65d is connected at the center of the rear end face, and a valve 65c is provided in the vicinity of the connecting portion. In addition, a large number of ventilation holes (hereinafter referred to as “outer cylinder ventilation holes”, not shown) are formed in the cylindrical side surface and the outer cylinder rear end surface of the outer cylinder 65a.
[0039]
The inner cylinder 65b is formed in a bottomed cylindrical shape slightly smaller in diameter than the outer cylinder 65a and is accommodated in the outer cylinder 65a. The end surface on the blower fan 47 side is opened and the inner guide pipe 65d side is opened. The end face (hereinafter referred to as “inner cylinder rear end face”) is closed. In addition, a large number of ventilation holes (hereinafter referred to as “inner cylinder ventilation holes”, not shown) are formed in the cylindrical side surface and the inner cylinder rear end surface of the inner cylinder 65b.
[0040]
Further, the inner cylinder 65b is configured to be rotatable by a predetermined angle about the cylinder axis as a rotation axis, and has a rotation drive mechanism such as a solenoid or a stepping motor, and rotates the cylinder axis. The position can be maintained after a normal rotation or a reverse rotation by a predetermined angle in any direction or the reverse direction of the rotation direction as the moving axis. In this case, when the inner cylinder 65b is rotated forward and stopped, the outer cylinder vent hole (not shown) and the inner cylinder vent hole are completely overlapped with each other so that the opening communicates. When 65b rotates in the reverse direction and stops, the outer cylinder vent hole (not shown) and the inner cylinder vent hole are completely displaced and the opening is closed. The movable drive mechanism is electrically connected to the air flow controller drive unit 64.
[0041]
The above-described valve 65c is electrically connected to the air flow controller drive unit 64, takes a position to close the passage to the main guide pipe 65d in the case of forward direction control, and takes the position of the main guide in the case of reverse direction control.

[0042]
The branch end of the branch guide pipe 65e is opened in the vicinity of the support function sending socket 41. The branch end of the branch guide pipe 65f is opened in the vicinity of the video signal receiving socket.
[0043]
The signal output terminals 62 b and 62 c are electrically connected to the main controller 60 and the external endoscope monitor device 5.
[0044]
Next, the operation of the endoscope processor 4 will be described.
First, when an operator operates the power switch 43 to turn on the power to start using the endoscope processor 4, the switch operation detection sensor (not shown) detects this switch operation. The data is output to a sub CPU (not shown) of the power controller 61. The sub CPU determines that this switch ON operation is not “specific time”, and sends a signal to that effect to the main CPU of the main controller 60 and switching of a power delivery section (not shown) in the power controller 61. A control signal is sent to a unit (not shown), and the power from the power supply terminal 62a is sent to the main controller 60.
[0045]
In the main controller 60, the main CPU (not shown) receives a signal indicating that it is not a specific time from the sub CPU, and sends a normal rotation drive control signal for rotating in the normal rotation direction to the blower fan driving unit 63. At the same time, a forward direction drive control signal for causing the air flow controller drive unit 64 to drive in the forward direction is sent.
[0046]
The blower fan drive unit 63 receives a normal rotation drive control signal from the main CPU and rotationally drives an electric motor (not shown) of the blower fan 47 in the normal rotation direction.
[0047]
At the same time, the airflow controller driving unit 64 receives the forward drive control signal from the main CPU and drives the airflow controller 65 in the forward direction. As a result, the rotation drive mechanism (not shown) rotates the inner cylinder 65b by a predetermined angle and stops, so that the outer cylinder vent hole (not shown) and the inner cylinder vent hole (not shown) are formed. A plurality of openings are formed in communication with each other, and the valve 65c is controlled in the forward direction so that the passage to the main guide pipe 65d is closed.
[0048]
For this reason, the air flow exactly the same as the air flow of the thick arrow shown in FIG. 4B is generated, and the inside of the housing 40 is thereby cooled. In this case, since the passage to the main guide pipe 65d is closed by the valve 65c, no air flow is generated in any direction in the main guide pipe 65d.
[0049]
Next, when the operator turns off the power by operating the power switch 43 to end the use of the endoscope processor 4, the switch operation detection sensor (not shown) detects this switch operation. And output to a sub CPU (not shown) of the power controller 61. The sub CPU determines that the switch-off operation is “specific time”, and sends a signal to that effect to the main CPU of the main controller 60, and also switches the power delivery section (not shown) in the power controller 61. A control signal is sent to a unit (not shown), and power from a storage battery (not shown) is sent to the main controller 60.
[0050]
In the main controller 60, in response to a signal indicating that “it is a specific time” from the sub CPU, the main CPU (not shown) sends a reverse drive control signal for rotating the blower fan drive unit 63 in the reverse direction.
[0051]
The blower fan drive unit 63 receives a reverse drive control signal from the main CPU and rotationally drives an electric motor (not shown) of the blower fan 47 in the reverse direction.
[0052]
For this reason, an air flow in the opposite direction to the air flow indicated by the thick arrows shown in FIG. As a result, dust is removed or cleaned by air pressure being applied to dust or the like that has accumulated or accumulated at various locations inside the housing 40 or by being blown away.
[0053]
The main CPU (not shown) sends the reverse direction drive control signal to the air flow controller drive unit 64 after performing the above-described cleaning inside the casing for a certain period of time. If it does in this way, the airflow controller drive part 64 will drive the airflow controller 65 in the reverse direction. As a result, the rotation drive mechanism (not shown) rotates the inner cylinder 65b backward by a predetermined angle and stops, so that the outer cylinder vent hole (not shown) and the inner cylinder vent hole (not shown) are formed. It completely shifts and all the outer cylinder vent holes of the outer cylinder 65a are closed. At the same time, the passage to the main guide pipe 65d is opened by the valve 65c.
[0054]
For this reason, an air flow is generated in the opposite direction to the air flow indicated by the thick arrows shown in FIG. 4B, and all of this air flow enters the main guide pipe 65d and further branches from the main guide pipe 65d. It is guided to 65e and 65f. Thereby, an air flow is blown to the support function sending socket 41 in the vicinity of the branch end of the branch guide pipe 65e, and dust or the like that has adhered or accumulated is removed. On the other hand, an air flow is also blown to the video signal receiving socket 42 in the vicinity of the branch end of the branch guide pipe 65f, and dust or the like that has adhered or accumulated is removed.
[0055]
During the air flow backflow described above, the main CPU extracts the notification information stored in the ROM (not shown) in the main controller 60, and outputs the notification information signal from the signal output terminals 62b and 62c to the external endoscope. Send to monitor device 5.
[0056]
Upon receiving the notification information signal, the endoscope monitor device 5 displays a telop image such as “Now, the endoscope processor is being cleaned.” Note that a speaker (not shown) may be incorporated in the endoscope monitor device 5 and a synthesized voice output such as “The inside of the endoscope processor housing is now being cleaned” may also be performed.
[0057]
The main controller 60 incorporates a timer (not shown) as hardware or software, and the main CPU executes the dust cleaning operation for the first predetermined period, and after the first predetermined period has elapsed, A power-off control signal is sent to the CPU. The sub CPU receives this and shuts off the power, and the endoscope processor 4 stops its function.
[0058]
In the above-described embodiment, the endoscope processor 4 corresponds to an endoscope processing support device. The blower fan 47 corresponds to a blower. The CPU (not shown), the blower fan drive unit 63, and the airflow controller drive unit 64 in the main controller 60 constitute a blow direction control means. Further, the CPU (not shown) in the main controller 60, the blower fan drive unit 63, the air flow controller drive unit 64, and the branch guide pipe 65e or 65f constitute reverse air flow supply control means. . A main CPU (not shown), a sub CPU (not shown), a switching unit (not shown), a storage battery (not shown), and the like correspond to power supply control means. Further, the main CPU (not shown) and the signal output terminals 62b and 62c constitute notification means.
[0059]

The above-described embodiment is an exemplification, and the present invention has substantially the same configuration as the technical idea described in the claims of the present invention, and any device that exhibits the same function and effect is the present invention. It is included in the technical scope of the invention.
[0060]
For example, in the above-described embodiment, the example in which the air flow is changed in the direction opposite to the normal direction in order to remove the dust in the housing by the air flow has been described, but the present invention is not limited to this, For example, a mechanism for swinging the entire blowing means (for example, the blowing fan 47) within a predetermined angle range may be provided to change and control the blowing direction. Or when changing a ventilation direction and performing cleaning, you may control so that a wind speed may be raised rather than the time of normal ventilation. As for the reversal control of the blowing direction, the CPU or the like may not be used as in the above embodiment, and the reversing switch of the electric motor (not shown) of the blowing fan may be merely linked with the power switch.
[0061]
In the above embodiment, in order to send an air flow to the support function sending socket 41 and the video signal receiving socket 42, an outer cylinder 65a, an inner cylinder 65b, a rotation drive mechanism (not shown), a valve 65c, Although the example using the air flow controller 65 configured by the main guide pipe 65d and the branch guide pipes 65e and 65f has been described, the present invention is not limited to this, and other configurations, for example, the valve 65c and the main The air flow controller 65 may be configured only by the guide pipe 65d and the branch guide pipes 65e and 65f, and the valve 65c may be opened only during reverse rotation to open the passage toward the guide pipe. Furthermore, even if only the main guide pipe 65d and the branch guide pipes 65e and 65f are provided except for the valve, a certain effect of socket cleaning can be exhibited. Alternatively, a dedicated blower fan for cleaning the inside of the housing or a dedicated blower fan for cleaning each socket may be provided.
[0062]
Further, when cleaning is performed at the time of power-off of the endoscope processing support device, a configuration other than an example using a storage battery as in the above embodiment may be used. For example, a main CPU (not shown) or a sub CPU (Not shown) provided with a timer (not shown) as hardware or software, delays the power-off for a first predetermined period and supplies power to the air blowing control means and the air blowing means. The power supply of the endoscope processing support apparatus may be shut off.
[0063]
The specific time may be set not only when the power is turned off but also when the power is turned on. In the case of cleaning when the power is turned on, it may be configured to change the air blowing direction of the air blowing means by a known mechanical mechanism using the power of the power on switch operation. Alternatively, a timer or the like is used to detect when a predetermined period has elapsed since the previous cleaning, and control is performed so that cleaning is performed when the power is turned on only when a predetermined period or more has elapsed since the previous cleaning. May be.
