That is, while the open pin rack 53a of the open pin moving rack portion 53 is formed from the front end surface to the base end surface, the duct rack 52a of the pipe moving rack portion 52 is a predetermined front side of the base end surface. It is set up to the position. That is, the number of teeth of the pipeline rack 52a of the pipeline moving rack portion 52 is set to a predetermined number.
The pitch of the teeth of the duct rack 52a and the pitch of the teeth of the open pin rack 53a are the same.

The operation of the fluid supply unit 50 configured as described above will be described.
When the fluid supply unit 50 is disposed at the initial position as shown in FIG. 7 and the like, when a control signal for connecting the fluid supply unit 50 to the endoscope 90 is input to the drive motor 61 from a control unit (not shown). The drive motor 61 is in a driving state. Then, the gear 64 meshed with the pipeline rack 52a and the open pin rack 53a is rotated, and the pipeline moving rack portion 52 and the open pin moving rack portion 53 hold the pipeline as the gear 64 rotates. The movement is started toward the block 51 direction.

When the tubes 175 and 176 are not connected to the ports 171 to 174 and the second valve 146 is in a closed state, the relief valve 169 is switched from a closed state to an open state when a certain pressure is exceeded.

  As shown in FIG. 29, the controller 162 of this embodiment is provided with a comparator 162a and an automatic attachment / detachment control circuit 162b. The comparator 162a receives a flow voltage value (Vsig) corresponding to the flow value measured by the flow meter 167 and a comparison voltage value (Vref) that is a discrimination threshold.

  The comparator 162a compares the flow voltage value with the comparison voltage value. If the flow voltage value is larger than the comparison voltage value as shown in FIG. If it is smaller than the comparison voltage value, it is determined that the tube is compatible with endoscope cleaning. Then, the comparator 162a outputs the determination result to the automatic attachment / detachment control circuit 162b.

  The determination by the comparator 162a is performed after a predetermined time has elapsed since the pump 163 was driven. That is, as shown in FIG. 30, the pump 163 is in a flow rate unstable region where the flow rate changes irregularly immediately after driving. Then, after a predetermined time has elapsed, the pump 163 enters the flow rate stable region, and thus the determination is performed within this flow rate stable region.

  The automatic attachment / detachment control circuit 162b is a logic that makes it impossible to supply voltage to the driving device 168 in any case when the determination result input from the comparator 162a is a Low signal notifying tube-compatible endoscope cleaning. Take the configuration. On the other hand, when the determination result input from the comparator 162a is a Hi signal notifying the unit-compatible endoscope cleaning, it is possible to supply voltage to the driving device 168.

  Note that the time until the flow rate stable region is reached after the pump is driven and the value of the comparison voltage value (Vref) are calculated in consideration. In addition, the tube-corresponding cleaning flow value (Vt) at the time of tube-corresponding endoscope cleaning and the unit-corresponding cleaning flow value (Va) at the time of unit-corresponding endoscope cleaning are measured in advance and compared based on this measurement result. Determine the voltage value.

Also, between the comparison voltage value and the tube-compatible cleaning flow value and unit-compatible cleaning flow value,
Va>Vref> Vt
The relationship is set.

  As described above, the control unit is provided with a comparator and an automatic attachment / detachment control circuit, and a flow rate output from the flowmeter regardless of the result determined from the scope ID registered in the RFID or the like after a certain time has elapsed since the start of cleaning. A logical configuration that makes it impossible to supply a voltage to the drive device in any case when a voltage value is determined by a comparator and the determination result of the comparator is a Low signal notifying tube-compatible endoscope cleaning By doing so, it is possible to reliably prevent the fluid supply unit from malfunctioning during the tube-compatible endoscope cleaning.

  In the present embodiment, a flow rate voltage value (Vsig) corresponding to a flow rate value measured by a flow meter is input to the detector, and a comparison voltage value (Vref) that is a discrimination threshold is input. However, the pressure voltage value and the comparison voltage value may be input to the detector instead of the flow voltage value (Vsig) and the comparison voltage value (Vref). In this case, a pressure gauge is provided instead of the flow meter. The pressure voltage value is a voltage value corresponding to the pressure value measured by the pressure gauge.

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