[0016] [Figure 1] FIG. 1 is a block diagram showing the functional configuration of a vacuum system including a portable power supply device according to an embodiment of the present invention. [Figure 2] FIG. 2 is a plan view showing the internal configuration of the portable power supply device according to the embodiment of the present invention, as viewed from the thickness direction. DETAILED DESCRIPTION OF THE INVENTION

[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A portable power supply device according to an embodiment of the present invention will now be described with reference to the accompanying drawings. Fig. 1 is a block diagram showing the functional configuration of a portable vacuum system 10 including a power supply device 12 according to an embodiment. Fig. 2 is a plan view, viewed from the thickness direction, showing the internal configuration of the power supply device 12 according to an embodiment. Note that, in the following, the X-axis, Y-axis, and Z-axis directions, which are orthogonal to one another in three-dimensional space, are parallel to each other. For example, the X-axis direction is parallel to the front-rear direction of the power supply device 12, the Y-axis direction is parallel to the left-right direction of the power supply device 12, and the Z-axis direction is parallel to the thickness direction of the power supply device 12.

[0018] As shown in FIGS. 1 and 2, a portable vacuum system 10 of the embodiment includes, for example, a portable power storage device 11, a power supply device 12, and an ion pump 13. The power supply device 12 includes, for example, a housing 21, a power receiving connector 22, a power supply connector 23, a circuit section 24, a high-voltage module 25a, an analog circuit 25b, a current sensor 26, and a heat dissipation member 27. The outer shape of the housing 21 is, for example, a rectangular box. Of the components of the power supply device 12 arranged inside the housing 21, the power receiving connector 22, the power supply connector 23, and the current sensor 26 are each partially exposed to the outside.

[0019] The power receiving connector 22 is, for example, a connector of a predetermined general-purpose interface standard that is connected to the portable power storage device 11. The predetermined general-purpose interface standard is, for example, the USB PD (Power Delivery) standard, which is a power supply standard compatible with a USB (Universal Serial Bus) Type-C terminal. The power receiving connector 22 receives power from the portable power storage device 11. Note that the portable power storage device 11 may be equipped with a power supply device including various types of batteries such as a primary battery and a fuel cell, instead of a secondary battery, or various types of electrical equipment that can supply power. The power supply connector 23 is, for example, a coaxial connector of a predetermined shape that is connected to various external devices such as the ion pump 13. The power supply connector 23 supplies the power output from the circuit section 24 to the ion pump 13.

[0020] The circuit unit 24 includes, for example, a circuit board on which a high-voltage module 25a and an analog circuit 25b are mounted. High voltage module 25a is, for example, a voltage conversion module including a plurality of switching elements, etc. High voltage module 25a performs desired voltage conversion, such as boosting the power supplied from portable power storage device 11, and also performs appropriate operations such as overcurrent protection. The analog circuit 25b outputs a control signal that controls, for example, the voltage conversion operation of the high-voltage module 25a.

[0021] The current sensor 26 detects, for example, the power supply current supplied from the power supply connector 23 to an external device such as the ion pump 13. The current sensor 26 is exposed to the outside of the housing 21, for example, and includes a digital or analog display unit that displays the detection result of the power supply current. For example, the display operation of the display unit of the current sensor 26 is switched on and off as appropriate in response to an operation by an operator or a preset switching timing, etc. The heat dissipation member 27 is, for example, a heat sink, and is arranged so as to be in contact with the high-voltage module 25a.

[0022] As described above, the portable power supply device 12 of the embodiment is provided with a power receiving connector 22 conforming to a predetermined general-purpose interface standard that is connected to the portable power storage device 11, thereby improving versatility, replaceability, and maintainability while being portable compared to, for example, a case where an external device is provided with a dedicated power storage device. By using the general-purpose portable power storage device 11 as the power source, it is possible to suppress an increase in costs required for configuring the device and improve the versatility, replaceability, and maintainability of the power source.

[0023] By providing the voltage conversion module 25a, it is possible to perform desired voltage conversion such as boosting the power supplied from the portable power storage device 11, and it is possible to easily ensure the specified voltage required for various external devices. By providing the current sensor 26, it is possible to notify the operator whether or not power is being supplied to the external device properly, thereby improving maintainability. By providing the heat dissipation member 27, even if the voltage conversion module 25a generates heat, it is possible to prevent the temperature from rising excessively.

[0024] (Variation) In the above-described embodiment, the external device is the ion pump 13, but is not limited to this and may be various electrical devices such as a photomultiplier tube provided in a scintillator detector, a multi-channel plate, or an electrostatic uniform coating device. In the above-described embodiment, the current sensor 26 has a digital or analog display unit, but this is not limiting and, for example, a current notification unit that notifies when the detected current is other than a predetermined current may be provided. The current notification unit may include, for example, a light such as a light-emitting diode that notifies by lighting, and a sound output unit such as a speaker, buzzer, or bell that notifies by sound.

[0025] The embodiments of the present invention are presented as examples and are not intended to limit the scope of the invention. These embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are intended to be included within the scope and spirit of the invention, as well as within the scope of the invention and its equivalents as defined in the claims.
