[0009] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In each drawing, the symbol FR indicates the front (front direction) of the projection system 1 in an installed state, the symbol UP indicates the upper side of the projection system 1, and the symbol RH indicates the right side of the projection system 1. Although not shown, the opposite direction of the symbol FR indicates the rear side of the projection system 1, the opposite direction of the symbol UP indicates the lower side of the projection system 1, and the opposite direction of the symbol RH indicates the left side of the projection system 1. In the description, directions such as front, back, left, right, and up and down are the same as the directions relative to the projection system 1 described above, unless otherwise specified.

[0010] [Embodiment 1] Fig. 1 is a left front perspective view of the projection system 1. Fig. 2 is a right rear perspective view of the projection system 1. Fig. 3 is a right rear perspective view of the projection system 1 when the grip part 150 is stored. Fig. 4 is a front view of the projection system 1. The projection system 1 is made up of a projector 10 that projects an image and a projector cart 20 that houses the projector 10.

[0011] The projector 10 has a housing 11, a light source unit, a light modulation unit, a projection lens unit 14, and a power supply board unit. When the projector 10 is turned on, power is supplied to the light source unit by the power supply board unit. Light emitted from the light source unit is incident on the light modulation unit. The light modulation unit modulates the light emitted from the light source unit. The light modulated by the light modulation unit is emitted outside the housing 11 by the projection lens unit 14, allowing an image to be projected onto the projection surface.

[0012] The housing 11 of the projector 10 is provided with an air intake 15 for intake of air and a heat exhaust 16 for exhaust of heat. In addition, the lower part of the housing 11 of the projector 10 is provided with legs 17 that can adjust the projection surface in the vertical direction.

[0013] The projector cart 20 accommodates the projector 10 and is capable of moving the projector cart 20. The projector cart 20 can be moved by human power or by a robot, for example.

[0014] 4, the projector cart 20 includes a substantially rectangular parallelepiped storage section 30. Inside the storage section 30, the projector 10 is stored.

[0015] The housing unit 30 includes an upper surface portion (fifth surface) 35 forming the top surface, a right surface portion 33 (third surface) and a left surface portion (fourth surface) 34 forming the left and right sides, a front surface portion (first surface) 31 and a rear surface portion 32 (second surface) forming the front and rear surfaces, and a lower surface portion (sixth surface) 36 forming the bottom surface. Each surface of the housing unit 30 may be composed of multiple surfaces. In this embodiment, the front surface portion 31 is composed of a vertical surface 31a relative to a horizontal floor and an inclined surface 31b intersecting with the vertical surface 31a. The upper surface portion 35 is provided approximately parallel to the horizontal floor. By providing such a horizontal surface, the housing unit 30 can be used as a stand for electronic devices and the like connected to the projector 10 housed in the housing unit 30.

[0016] An air intake hole 37 is formed on the front surface of the housing section 30. Heat exhaust holes 38 are formed on the right surface 33 and rear surface 32 of the housing section 30. The air intake hole 37 and the heat exhaust hole 38 are provided in positions that do not interfere with the intake of air and the exhaust of heat from the projector 10 placed inside the projector cart 20. The air intake hole 37 and the heat exhaust hole 38 may also be configured with a plurality of slit holes. This makes it possible to prevent the temperature inside the housing section 30 from rising due to the exhaust air from the projector 10, even when the projector 10 is placed inside the housing section 30. In other words, since the projector 10 can exhaust the exhaust air to the outside of the housing section 30 of the projector cart 20, it is possible to prevent the exhaust air from the projector 10 from accumulating inside the housing section 30, and the air intake operation and the heat exhaust operation can be performed without the temperature inside the housing section 30 rising.

[0017] Wheels 39 are provided on the lower surface 36 of the storage section 30. The wheels 39 are provided at each of the four corners of the lower surface 36. The wheels 39 are provided with stoppers, and the stoppers can restrict the rotation of the wheels 39.

[0018] At least one of the top surface 35 and the front surface 31 of the housing 30 is provided with a window 40 for emitting the projected light from the projector 10 to the outside of the housing 30. The window 40 is provided so as not to block the projected light from the projector 10. The window 40 may also be provided by removing the top surface 35 and the front surface 31. In other words, the top surface 35 and the front surface 31 of the housing 30 are formed to be removable, and the projection system 1 can also be used with the top surface 35 and the front surface 31 removed.

[0019] In this embodiment, a partition plate 41 is provided in the housing unit 30, dividing the housing unit 30 into an upper space and a lower space. In this way, the housing unit 30 may be divided into multiple spaces. By dividing the housing unit 30 into multiple spaces, the installation height of the projector 10 can be roughly adjusted to match the position of the projection lens unit 14 of the projector 10 and the position from which the projector 10 projects. In addition, the space below the partition plate 41 can be used as a storage space for related parts such as cables used for machinery and wiring other than the projector 10.

[0020] The housing section 30 is provided with a grip section 150 that serves as a handle when moving the projector cart 20. The grip section 150 is provided at the rear end of the housing section 30. In this embodiment, the grip section 150 has a first support section 151 and a second support section 152 that extend in the vertical direction, and a connection section 153 that connects the upper ends of the first support section 151 and the second support section 152. In other words, the grip section 150 is formed in an inverted U shape when viewed from the front.

[0021] An operation panel (first operation unit) 155 is provided on the connection unit 153 of the grip unit 150. The operation panel 155 is a touch display, and the user can perform operations such as powering on the projector 10 and performing keystone correction by touching icons displayed on the touch display.

[0022] The grip portion 150 is displaceable and is formed so that it can be inserted through the upper surface portion 35 and stored inside the storage portion 30. Examples of a displacement means for storing the grip portion 150 in the storage portion 30 include an extendable structure and a foldable structure. The grip portion 150 is exposed from the storage portion 30 and its length can be freely changed. In other words, the storage state in the present disclosure does not only refer to a state in which the entire grip portion 150 is stored inside the storage portion 30, but also to a state in which part of the grip portion 150 is stored inside the storage portion 30 and part is exposed outside the storage portion 30.

[0023] The gripping portion 150 is formed so that when it is fully extended, the length from the upper surface 35 of the storage portion 30 to the operation panel 155 is longer than the length from the lower surface 36 to the upper surface 35. By providing the operation panel 155 on the gripping portion 150 in this way, it is not necessary to remove the projector 10 from the storage portion 30 in order to change the settings of the projector 10, and the projector cart 20 can be moved in an upright position.

[0024] The gripping portion 150 can be retracted until the uppermost end 150 a of the gripping portion 150 is at a position equal to or lower than the upper surface portion 35 of the storage portion 30 . A notch 35a for accommodating the connection part 153 is provided at the rear end of the top surface 35 of the housing part 30. A notch 32a is also provided at the upper end of the rear surface 32 so that a part of the accommodated grip part 150 is exposed at the outer end of the housing part 30. These notches 32a and 35a create a gap around the connection part 153 of the grip part 150 when the grip part 150 is accommodated in the housing part 30, allowing an operator to grasp and remove the grip part 150. Furthermore, when the grip part 150 is accommodated, the operation panel 155 is exposed to the outside. In other words, the operation panel 155 is located outside the housing part 30, and a user can operate the projector 10 using the operation panel 155 even when the grip part 150 is accommodated.

[0025] The housing section 30 is provided with a cable (not shown) for supplying power to the projector 10 and a wiring hole (not shown) for wiring the cable.

[0026] At least a portion of the first support section 151, the second support section 152, and a portion of the connection section 153 have a hollow structure. A circuit that is controlled by operating the operation panel 155 is provided in the internal cavity. The circuit extends to the housing section 30 and is connected to the projector 10.

[0027] The projection system 1 is installed through three main steps. The first step is to grip the grip portion 150 of the projection system 1 and move the wheels 39. This step allows the position of the projection system 1 to be roughly determined. The second step is to operate the first operating unit 155 provided on the grip portion 150 to turn on the power of the projector 10 mounted on the projection system 1. The third step is to grip the grip portion 150 and make fine position adjustments to the projection system 1. These steps allow the position of the projection system 1 to be easily adjusted.

[0028] [Effects of the First Embodiment] As described above, according to the first embodiment to which the present invention is applied, a projector 10 is provided, and a projector cart 20 that houses the projector 10, and the projector 10 includes a housing 11, a light source unit housed in the housing 11, a light modulation unit housed in the housing 11 that modulates light emitted from the light source unit, a projection lens unit 14 that emits the light modulated by the light modulation unit to the outside of the housing 11, and a power supply board unit housed in the housing 11 that supplies power to the light source unit, and when the projector 10 is in use, the projector cart 20 includes a housing unit 30 that can house the projector 10 and can emit the light emitted from the projection lens unit 14 to the outside of the projector cart 20, wheels 39 provided vertically below the housing unit 30, and an operation panel 155 that is located vertically above the housing unit 30 and is used to change the electrical state of the power supply board unit. This makes it easier for the worker to operate the projector 10 while standing, thereby improving the operability of the projection system 1 and the projector cart 20.

[0029] The projector cart (20) includes a handle (150) provided on the housing (30), the handle (150) being positioned vertically above the housing (30), and an operation panel (155) being provided on the handle (150). This allows the projection system 1 to be moved and the projector 10 to be operated using the grip portion 150, making it easier for the worker to operate the projector 10 while in an upright position, thereby improving the operability of the projection system 1.

[0030] The operation panel 155 can be used to turn the power of the projector 10 on and off. According to this, the grip portion 150 can be used to operate the power supply of the projector 10, and therefore the operability of the projection system 1 is improved.

[0031] The operation panel 155 can cause the projector 10 to perform keystone correction on the image that the projector 10 projects. According to this, the handle 150 can be used to perform keystone correction of the projector 10, and the operability of the projection system 1 is improved.

[0032] In use, the grip portion 150 is configured so that at least a portion thereof can be stored at a position equal to or below the top surface of the storage portion 30, and when the grip portion 150 is stored, the operation panel 155 faces outward from the storage portion 30. This allows the user to operate the operation panel 155 while storing the grip portion 150, thereby improving the operability of the projection system 1.

[0033] The storage section 30 has a front surface 31, a rear surface 32 opposite the front surface 31, a right surface 33 intersecting the front surface 31 and the rear surface 32, a left surface 34 opposite the right surface 33 and intersecting the front surface 31 and the rear surface 32, an upper surface 35 intersecting the front surface 31, the rear surface 32, the right surface 33, and the left surface 34, and a lower surface 36 opposite the upper surface 35 and intersecting the front surface 31, the rear surface 32, the right surface 33, and the left surface 34. At least one of the support portions 35 has a window portion 40 for emitting the projection light of the projector 10 to the outside of the storage portion 30, wheels 39 are provided on the lower surface portion 36, and a grip portion 150 is provided on the upper surface portion 35, the grip portion 150 including a first support portion 151 connected to the upper surface portion 35, a second support portion 152 connected to the upper surface portion 35, and a connection portion 153 connecting the first support portion 151 and the second support portion 152, and an operation panel 155 is provided on the connection portion 153. This reduces the risk of incorrect operation when the user grasps the first support portion 151 and the second support portion 152 and moves the projection system 1 and the projector cart 20.

[0034] When in use, the vertical length of the portion of the first support portion 151 above the upper surface 35 is greater than the distance from the upper surface 35 to the lower surface 36 of the storage portion 30, and the distance from the upper surface 35 to the operation panel 155 is greater than the distance from the upper surface 35 to the lower surface 36 of the storage portion 30. This allows the operator to use the grip portion 150 to operate the operation panel 155 while maintaining an upright posture, improving operability when the projector 10 is stored.

[0035] The first support column 151 has a hollow structure, and a circuit controlled by operation of the operation panel 155 is provided in the hollow structure, and wiring electrically connected to the circuit reaches the storage section 30 through the hollow structure. This allows the projector cart 20 to operate the projector 10 via a wired connection.

[0036] A method for installing a projection system 1, the projection system 1 comprising a projector 10, a storage section 30 for storing the projector 10, wheels 39 provided on the storage section 30, a gripping section 150 provided on the storage section 30, and an operation panel 155 provided on the gripping section 150 for changing the electrical state of the projector 10, includes a first step of gripping the gripping section 150 and moving the wheels 39, a second step of operating the operation panel 155 after the first step to turn on the power of the projector, and a third step of gripping the gripping section 150 after the second step to adjust the position of the projection system 1. According to this, the gripping portion 150 allows the projection system 1 to be moved and operated while maintaining an upright posture, thereby improving the operability of the projection system 1 and the projector cart 20.
