Description

  The present invention relates to a velocity measuring device using a microwave.

  A device using a Doppler sensor is known as a velocity measuring device that measures the maximum velocity of a moving measuring object. In this method, a microwave is applied to an object that is a non-measurement object, and a reflected wave from the object is measured. When the object is moving with respect to the traveling direction of the microwave, the frequency of the reflected wave changes due to the Doppler effect, so the speed of the object can be calculated by comparing this with the frequency of the emitted wave. it can. A conventional speed measuring device using this type of Doppler sensor is generally used to measure the speed (ball speed) of a ball thrown by a pitcher in baseball.

This type of speed measuring device has a shape that includes a substantially cylindrical main body in which a measuring device is accommodated, and a handle portion that projects downward from the main body. In this type of speed measuring device, the measurer holds the handle portion by hand and measures the front surface of the main body toward the measurement object. In general, this type of speed measuring device is well known for measuring the ball speed of a ball thrown by a pitcher, but it is also used for the ball speed of a tennis serve.

Moreover, as shown in Patent Document 1, there is a case in which the case body is a substantially rectangular parallelepiped rectangular box. This type can be left on the ground.

JP-A-11-212814

  A conventional speed measuring device having a handle portion is suitable for measuring a ball speed, but is not suitable for measuring other measuring objects. Moreover, although the apparatus disclosed by patent document 1 can be set | placed on the ground, it is not suitable for carrying out the general use of measuring with a hand for the measurement of a ball speed. Furthermore, there is a problem that it is desired to appropriately measure a plurality of different types of measurement objects. In addition, there is a problem that the direction of microwave transmission and reception is difficult to understand at a glance.

In order to solve the above problems, the present invention includes (1) an antenna that transmits and receives microwaves, a control unit that performs control for measuring the velocity of a measurement object based on a signal output from the antenna, A case main body including the antenna and the control unit, and the case main body includes a main body portion and an antenna housing portion (corresponding to the “front portion 10b” in the embodiment) provided on the distal end side of the main body portion. And the length of the antenna housing portion in the vertical direction is longer than the length of the main body portion in the vertical direction.

As a result, antennas that transmit and receive microwaves include horn antennas and patch antennas, but the surface for transmitting and receiving microwaves is relatively wide. However, the size and shape of the main body can be made smaller than that. Therefore, the main body can be easily held by hand. That is, if the antenna is housed in the case body with the antenna transmitting / receiving surface facing forward, the case body should be held by hand, assuming that the case body has substantially the same longitudinal cross-sectional shape in the front-rear direction. In the present invention, the main body becomes smaller and can be held by hand.

In addition, the length of the antenna housing portion is vertical, that is, the height / thickness is longer than that of the main body portion. However, the spreading direction may be both the vertical direction as in the embodiment, or one side. Only it is good. Moreover, even when it is made to spread to both upper and lower sides, the protrusion amount may differ. When it is made to spread only upward, the lower surface of the case body becomes flat, so if it is placed on the ground as it is, it can be installed horizontally with the ground. Therefore, if the transmission / reception direction of the antenna is parallel to the lower surface of the case body, the transmission / reception direction of the antenna can also be horizontal. In addition, when the antenna housing portion protrudes downward, when the case main body is installed on the ground as it is, the case main body is in a posture facing obliquely upward. Therefore, if the transmission / reception direction of the antenna is parallel to the lower surface of the case body, the transmission / reception direction of the antenna is obliquely upward, but the transmission / reception direction of the microwave can be set by appropriately setting the amount of protrusion downward of the antenna housing portion. The angle can be reduced even when the surface is substantially horizontal to the ground or obliquely upward. Therefore, in this invention, it can respond to the measurement in a different aspect, when measuring by holding with a hand and when installing and measuring on the ground etc.

(2) The antenna may be a horn antenna, and the antenna housing portion may be a horn antenna housing portion whose height gradually increases from the main body portion toward the tip. In other words, a horn antenna that transmits and receives microwaves, a control unit that performs control for measuring the speed of a measurement object based on a signal output from the horn antenna, and a case main body that includes the horn antenna and the control unit The case main body has a main body portion and a horn antenna storage portion (corresponding to the “front portion 10b” in the embodiment) whose height gradually increases from the main body portion toward the tip. May be.

As for the shape of the case main body, the tip portion spreads in a trumpet shape, and the horn antenna is housed in that position, and the orientation of the horn antenna can be easily estimated. In addition, since the main body portion can be made thinner than the horn antenna housing portion, the main body portion can be easily held by hand. Therefore, for example, when measuring the ball velocity, etc., the case body can be appropriately operated by hand, and the transmitting / receiving surface of the horn antenna can be easily faced to the measuring object such as the ball. it can.

  (3) The speed of the object to be measured is at least one of the speed of the ball thrown by the pitcher, the swing speed of the bat, the speed of the hit ball, the run speed of the runner, the travel speed of the automobile, the swing speed of the golf club, It is possible to set at least one of the speeds of the hit balls. The former measures using a tripod or by hand, and the latter measures on the ground. Thus, in this invention, it becomes a suitable structure for any measurement aspect.

  (4) A display portion may be provided on the upper surface of the main body portion. Although the upper surface of the horn antenna storage portion is an inclined surface, the display portion is easy to see even when viewed from the horn antenna side by providing the display portion on the upper surface of the main body portion on the rear side.

  (5) A second antenna may be disposed above the antenna (for example, the upper surface of the horn antenna). In this way, the sensitivity of the second antenna can be improved. The second antenna corresponds to the remote control antenna 24 in the embodiment.

  (6) A convex portion protruding upward may be provided on the upper surface of the antenna housing portion, and at least a part of the second antenna may be positioned within the convex portion. In this way, it is possible to easily understand the position of the second antenna, and it is possible to suppress the external dimension of the case body from being increased more than necessary.

  (7) A convex portion having a remote control receiving portion (including wireless / infrared rays) may be provided on the upper surface of the case body, and at least a part of the sighting device may be provided on the convex portion.

  (8) A start button for starting measurement may be disposed on the upper surface of the case body. Easy to operate. In particular, even when placed on the ground, since the start button is on the top, it can be instructed by a simple operation such as pressing from above. The start button corresponds to the start / stop button 15 of the embodiment. In the embodiment, the function of the stop button for forcibly terminating is also used, but a button for giving only a start instruction may be used. Note that when a button other than the start button is provided on the upper surface of the case body, the size of the start button may be larger than the other buttons.

  (9) The display color of the start button may be different from the surrounding color of the upper surface of the case body. Since the position of the start button is conspicuous, operability is improved. For example, it contributes to the prevention of forgetting to press the start button.

  (10) It is preferable to provide a plurality of protrusions on the same straight line on the upper surface of the case body, which indicate the transmission / reception directions of microwaves in the antenna. In the embodiment, it corresponds to the first and second protrusions 20a and 20b. Although the 2nd protrusion 20b was provided on the convex part, even if it provides in another position, it does not disturb. However, by providing on the convex portion as in the embodiment, it can be efficiently installed at an appropriate height position.

  (11) A plurality of legs projecting downward may be provided on the lower surface of the case body. When measuring the ball speed of a golf ball or the swing speed of a golf club, the speed measurement device is placed on the ground, but by supporting with multiple legs, it is stable even if the ground is uneven. And can be installed horizontally. In particular, as in the embodiment, in the case where the horn antenna spreads up and down, and the lower surface of the case main body has an inclined surface extending downward at the front end side, the main body can be provided by providing a leg portion. Lift the part and support in a stable posture.

  (12) A battery box may be provided below the case body, and a battery lid that covers the battery box and at least one of the plurality of legs may be integrated. By integrating the battery lid and the leg portion, a battery with an appropriate size and shape can be efficiently installed at an appropriate location.

(13) The plurality of leg portions may be arranged with a space in front and rear. If it does in this way, a palm can be put in the space part and it can have a main-body part, and can hold it stably. Therefore, it is suitable for the case where measurement is performed by hand.
(14) A tripod mounting portion may be provided on the bottom surface of the leg portion located on the front side of the space.

  (15) At least one of the plurality of legs may be provided with a recess for hooking a finger. In this way, it is suitable to operate with a hand in a general usage method such as measuring the ball speed of a baseball.

  (16) A horizontal line may be provided on a side surface of the case body. In the embodiment, the case main body is configured by abutting the upper case 11 and the lower case 12, and a horizontal line is formed at a joint portion of the abutting. However, a separate line may be formed. If it does in this way, it can be checked easily whether it is in a horizontal state. In the case where a horizontal line is formed at the butted joint, a waterproof packing may be provided inside the case along the horizontal line.

  In the present invention, the direction of the antenna can be easily understood, and the transmission / reception direction of the microwave can be known at a glance, so that the antenna can be installed in the correct direction. Furthermore, it can be measured in various manners, such as being held by hand or installed on the ground. Further, when a horn antenna is used as an antenna and the center position in the vertical direction of the horn antenna is matched with the center position in the vertical direction of the case body, the transmission / reception direction of the microwave can be recognized more reliably.

  Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings. The speed measuring device uses a microwave Doppler sensor, and based on the Doppler signal output from the microwave Doppler sensor (actually, appropriately amplifies), calculates the speed by performing arithmetic processing in the control unit, The result is output to the display unit.

And the speed measuring device of this embodiment can measure the speed of a different kind of measuring object by mode change. For example, a pitching mode that measures the speed of the ball (initial speed, final speed, etc.), a batting mode that measures the swing speed of the bat and the speed of the hit ball, and a short distance mode that measures the running speed of a short-distance runner And a golf mode for obtaining the swing speed of the golf club, the speed of the hit ball, the estimated flight distance, and the like, and an automobile mode for measuring the running speed of the automobile. In either mode, there is a single mode and a continuous mode. The single-shot mode is a mode in which the measurement is terminated and the result is displayed for each movement of the measurement object. The continuous mode is a mode for continuously recording measurement data accompanying a plurality of movements.

And the case main body 10 of a speed measuring device has the flat rectangular main-body part 10a, and the front site | part 10b which is provided in the front side of the main-body site | part 10a, and spreads continuously in a trumpet shape. As the thickness (height) of the front portion 10b goes to the front (tip), the front portion 10b becomes gradually longer in the vertical direction. Therefore, the line connecting the center positions of the upper and lower surfaces of the case body 10 is positioned on a straight line. Similarly, the front part 10b has a shape that spreads evenly in the left-right direction as it goes forward.

  Since the main body part 10a is a part that the user holds with his / her hand, the body part 10a is set to a dimension and shape that is easy to hold. As will be described later, since the horn antenna 23 is built in the front part 10b, the upper and lower surfaces of the front part 10b are set to dimensions and shapes along the inclined surface of the horn antenna 23 extending vertically.

The horn antenna 23 may be formed by combining a plurality of metal members by pressing a metal plate (such as tin or aluminum) or by sheet metal processing. If the metal members are formed in combination, minute vibrations are likely to occur, and the measurement result may not be an accurate value. Therefore, the horn antenna 23 of the present embodiment is configured by integrally forming metal by die casting, casting, shaving, or the like. In particular, this device can also be used to measure the speed of the measurement object, but when the measurement is held in hand, the horn antenna 23 tends to vibrate and the measurement result does not become an accurate value. There is. However, in this embodiment, since the horn antenna 23 is formed by integral formation, the vibration of the horn antenna 23 when held in the hand can be suppressed, and the measurement result can be kept accurate.

The case main body 10 is configured by abutting an upper case 11 and a lower case 12 that are divided into two vertically. The upper case 11 is opened at the lower side and the front side, and the lower case 12 is opened at the upper side and the front side. The size and shape of the lower end edge of the upper case 11 and the upper end edge of the lower case 12 coincide with each other, and the case main body 10 is closed except for the front opening by abutting the cases 11 and 12 together. And the waterproof packing 37 is interposed between the contact surfaces of these both cases 11 and 12, and it is set as the waterproof structure.

And the upper case 11 is provided with the flat part 11a which comprises the main-body site | part 10a of the main body case 10, and the enlarged part 11b extended in the up-down direction continuously formed in front of the flat part 11a. The lower case 12 includes a flat portion 12a that constitutes the main body portion 10a of the main body case 10, and a curved portion 12b that is continuously formed in front of the flat portion 12a and curves downward. The height of the flat portion 11a of the upper case 11 and the height of the flat portion 12a of the lower case 12 are substantially the same. Thereby, the contact surface of both flat part 11a, 12a used as the joining surface of the upper case 11 and the lower case 12 is located in the center position of the up-down direction of the main body site | part 10a. Therefore, the line L1 formed on the joint surface between the two also has a linear shape and is disposed so as to proceed in the longitudinal direction in the center of the main body portion 10a. By making the line L1 conspicuous, it is possible to make it easy to imagine the traveling direction of the microwave emitted from the horn antenna 23.

  In particular, in the present embodiment, as shown in FIG. 9 and the like, the vertical center line L3 of the horn antenna 23 and the line L1 connecting the center positions of the upper and lower surfaces of the case body 10 are positioned in the same horizontal plane. Therefore, it becomes easier to understand the direction in which the microwave travels. Of course, it is not always necessary that the vertical center lines of the horn antenna 23 and the case main body 10 are in the same plane. This is preferable because the direction of travel is known.

  On the other hand, the front part 10b of the main body part 10 is formed by the enlarged part 11b of the upper case 11 and the curved part 12b of the lower case 12, and the enlarged part 11b has its upper and lower surfaces enlarged in the vertical direction. Along with this, the upper surface of the curved portion 12b of the lower case 12 joined to the lower surface also gradually descends. Furthermore, the height and width of the frame local portion 12b in the vertical direction are gradually reduced toward the front. As a result, the line L2 at the joining portion of the enlarged portion 11b and the bending portion 12b constituting the front portion 10b moves while curving downward as it goes forward from the line L1 on the straight line, and the front portion At the front end position of 10b, it almost reaches the lower end position. That is, at the front end position of the case main body 10, the upper case 11 is positioned almost entirely, and the lower case 12 constitutes the lower surface.

Since the upper case 11 and the lower case 12 are open at the front surface, a flat lid member 13 is attached to the opening portion and closed. Further, the color of the lid member 13 (for example, a dark color such as black or dark gray) is made different from the color of the side surface or front surface of the upper case 11 and the lower case 12 (for example, a bright color such as silver). Thereby, the presence position of the cover member 13 becomes clear.

Further, as shown in the left side of FIG. 9 and FIG. 5, the shape of the opening surface of the horn antenna 23 and the shape of the lid member 13 are substantially the same, or the lid member 13 is moved by the spread of the radio wave emitted from the horn antenna. By adopting the enlarged shape, the user can unintentionally place it in an appropriate direction or remove an obstacle between the measurement object existing in the direction of radio wave emission. An opening (window hole) having an appropriate size and shape is provided at a predetermined position on the upper surface of the flat portion 11a of the upper case 11, and the display panel 14, the start / stop button 15 and the operation are opposed to the opening. The switch button 16 and the power switch button 17 are exposed. The display panel 14 is composed of a liquid crystal display or the like, forms a relatively large rectangular display area, draws a speed measurement result, and draws a menu item at the time of setting.

The start / stop button 15 has a rectangular planar shape, and its upper surface protrudes from the upper surface of the upper case 11. The start / stop button 15 controls the start / end of measurement. The control unit built in the apparatus starts measurement when it detects that the start button 15 is pressed, and then ends measurement when it detects that the start button 15 is pressed. Further, the color of the start / stop button 15 is made different from the color of the upper surface of the upper case 11 and the other buttons 16 and 17. For example, the upper surface of the upper case 11 may be a calm color such as black or dark gray, and the start / stop button 15 may be an orange / warm color or other bright and conspicuous color. As a result, the start / stop button 15 is emphasized, and it becomes easier to operate the start / stop button 15 that is operated more frequently than other buttons, such as measurement start and stop.

  The operation switch button 16 includes four selection keys arranged at intervals of 90 degrees on the front, rear, left and right sides, and a confirmation key provided at the center. The user operates these appropriate keys, selects and confirms menu items displayed on the display panel 14, and gives predetermined instructions. That is, the control unit draws a menu screen on the display panel 14 when power is turned on or when a predetermined button operation is recognized, and when the selection key is detected, the control unit moves the selection candidate item in the designated direction and confirms it. When a key press is detected, processing corresponding to the item that was the selection candidate item at that time is executed.

Furthermore, the start / stop button 15 and the operation switch button 16 protrude upward from the upper surface of the upper case 11 so that the user can easily press them. Further, a structure may be adopted in which the button is easily pressed by lowering the periphery of the button from the upper surface of the upper case 11. Further, a combination thereof, that is, a protrusion from the upper case, and the periphery of the button may be lowered by one step. By such a combination, the operability is the best. Furthermore, by making the planar shape of the start / stop button 15 relatively large with a rectangle extending in the width direction of the case main body 10, the user can operate it without directly looking at the upper surface of the upper case 11. Further, by providing the body portion 10a in a place where it can be operated using the fingers of the hand that is held with one hand, the operation with one hand is possible, and the position of the start / stop button 15 is also the finger. By appropriately extending the position, it can be operated without looking at the start / stop button 15 like a blind touch. Therefore, for example, the start / stop button 15 adopts the above-mentioned combination, the operation switch button 16 adopts a structure that protrudes upward from the upper surface of the upper case 11, and the power button 17 constitutes the upper case 11. Therefore, the start / stop button 15 has the best operability, and then the operation switch button 16 and the power button 17 has the lowest operability.

  On the other hand, the power button 17 is used by the user to give a command to turn on / off the power of the speed measuring device. When the power button 17 is pressed in the power off state, the power is turned on, and in the power on state. When the power button 17 is pressed, the power is shut off. In order to prevent the power from being cut off accidentally during use, the upper surface of the power button 17 is installed at a position deeper below the upper surface of the upper case 11, and the size and shape are also reduced. Furthermore, when the power is shut off, it may be a condition that it is long-pressed (continuously pressed for a predetermined number of seconds). Of course, it is not always necessary to set the upper surface of the upper case 11 below the upper surface, and the same effect can be obtained by making the upper surface of the power button 17 and the upper surface of the upper case 11 flush with each other or reducing the protrusion amount. Is obtained.

  On the upper surface of the enlarged portion 11b of the upper case 11, a convex portion 11d that protrudes upward is provided. The convex portion 11d is provided at the center in the width direction. Further, a first protrusion 20a is formed at the center of the upper piece of the front surface of the upper case 11 so as to extend in the front-rear direction on the center line of the speed measuring device, and further, the front center of the upper surface of the convex portion 11d, that is, A second protrusion 20b is formed on the center line of the speed measuring device so as to extend in the front-rear direction. A line connecting the first and second protrusions 20a and 20b coincides with the center line of the speed measuring device. Further, as shown in FIGS. 4 to 6 and the like, the first protrusion 20a is located at the uppermost position of the speed measuring device. Further, the second protrusion 20b is also positioned at substantially the same height as the first protrusion 20a. Therefore, when the speed measuring device is viewed from the rear side, the first and second protrusions 20a and 20b can serve as a sight and can be easily faced in the moving direction of the measurement object.

Further, inside the case body 10, electronic circuits / components for executing various modes are mounted at appropriate positions. A part of the horn antenna 23 is installed in the front part of the case body 10 as shown in FIGS. The size and shape of the horn antenna 23 is set so as to conform to the inner surface shape of the enlarged portion of the upper case, which is shown in a removed state in FIGS. Further, a remote control antenna 24 mounted on a circuit board 25 is disposed on the upper surface side of the horn antenna 23. The remote control antenna 24 communicates with a remote control device (not shown), and the control unit receives various commands from the remote control to perform various settings and controls, and transmits measurement results to the remote control device. To do. A part or all of the remote control antenna 24 is housed in a convex portion 11 d provided on the upper case 11.

Thus, the sensitivity is improved by installing the remote control antenna 24 above the horn antenna 23 and positioning the remote control antenna 24 above the whole speed measuring device. Further, the user can easily guess the position of the remote control antenna 24 by knowing that the remote control antenna 24 is located in the convex portion 11d, and direct the remote control device to the convex portion 11d (remote control antenna 24). By operating the remote controller, a better communication environment can be constructed.

Further, as described above, the second projection 20b is provided on the convex portion 11d for storing the remote control antenna 24 to serve as a sighting device, so that the speed measurement device is installed toward the measurement object. In addition, the position of the remote control antenna 24 can be made conscious, and the second protrusion 20b can be made conscious when using the remote control so that the presence of the sighting device can be made conscious.

  In the present embodiment, the wireless remote controller that wirelessly transmits and receives signals to and from the remote control is configured to receive wirelessly by the remote control antenna 24. However, the infrared remote controller that transmits and receives signals by infrared light is used, and infrared transmission and reception is performed instead of the remote control antenna. A vessel may be provided in the convex portion 11d. In this case, a material that transmits infrared rays may be used for the upper surface and side surfaces of the convex portion 11d. In this way, it can be easily recognized that the direction in which the infrared remote controller should be directed is the direction of the convex portion 11d, so that it becomes easier for the infrared remote controller to be operated in the direction of the convex portion 11d. This makes it easier to receive remote control signals from around this unit. As a result, the remote control operation can be performed reliably.

Further, as shown in FIG. 6 and the like, an elastically deformable terminal protective cover 22 made of rubber, resin or the like is provided at a predetermined position on the side surface of the upper case 11. The terminal protective cover 22 is connected to a protruding piece provided on the lower case 12 at one end 22a on the back surface side. The terminal protective cover 22 can be opened and closed with the one end 22a as a reference. When the terminal protective cover 22 is opened, the USB connector 26 and the memory card slot 27 are exposed as shown in FIG. Data can be transmitted / received to / from an external device such as a personal computer connected by a cable via the USB connector 26. Further, by mounting a predetermined memory card in the memory card slot 27, the measurement result can be recorded on the memory card, and the measurement result can be transferred to an external device using the memory card as a medium. The memory card stores data for the speed measuring device to execute various modes, and the control unit can operate while using the data stored in the memory card.

  A first leg 12c that protrudes downward is provided behind the lower surface of the lower case 12. Further, a second leg portion 12 d that protrudes downward is provided in front of the lower surface of the lower case 12. For example, when measuring the swing speed of a golf club or the ball speed of a golf ball in the golf mode, the object to be measured moves near the ground, so the speed measuring device is also installed on the ground. At this time, by placing the lower surfaces of the first leg portions 12c, 12d on the ground, the case main body 10 can be in a desired orientation / posture. For example, when the lower surfaces of the first leg portion 12c and the second leg portion 12d are flat and arranged on the same plane, and the same plane is parallel to the main body portion 10a of the case main body 10, the speed measuring device is When placed on the ground, the direction of the speed measuring device is parallel to the direction of the ground.

Further, in the present embodiment, the first leg portion 12c and the second leg portion 12d are separated by a predetermined distance, and a space is formed between them. Accordingly, even when the main body portion 10a is held by hand, the palm can be positioned in the space, and the presence of the second leg portion 12d does not get in the way and is easy to hold. In addition, the first leg portion 12c has a U-shaped flat surface so as to be provided with a recess 12f so that it can be firmly held by inserting a finger. Thus, the operability is improved even when the ball speed is measured by hand with the hand as in the pitching mode and the ball speed is measured.

The first leg 12c is integrally formed with the battery lid 12e. That is, as shown in FIGS. 11 and 12, a battery box 30 is provided in the rear region of the lower case 12, and a plurality of batteries 31 are accommodated in the battery box 30. On the periphery of the electronic box 30, an endless waterproof packing 38 is disposed at a portion facing the periphery of the electronic lid 12 e. Thus, when the battery lid 12e is mounted so as to close the electronic box 30, the waterproof packing 38 is in close contact with the entire inner peripheral surface of the battery lid 12e. This prevents water or the like from entering from the periphery of the battery lid 12e.

  The internal circuit of the speed measuring device operates in accordance with the power supply from the battery 31. Thus, the number of parts can be reduced by integrally forming the battery lid 12e and the first leg 12c. In addition, by positioning the battery 31 at the rear end of the case body 10, the battery cover 12 e is also located in the rear region of the lower case, while the first leg 12 c is also installed at the front and rear of the case body 10. It is preferable to be located in the rear region from the point of supporting at both ends. If the first leg portion 12c and the battery lid 12e are formed separately, the size and shape of each of the first leg portion 12c and the battery lid 12e are reduced. However, the first leg portion 12c can be appropriately sized by integrating them. The desired dimensional shape can be taken. With such a configuration, when the speed measuring device is held by hand, the battery part on the rear end side of the case body 10 is gripped, so that the weight of the battery can be reliably supported by hand.

Further, the second leg portion 12d includes a tripod attachment portion 12g on which a tripod 35 (a part of the attachment portion at the upper end of the tripod is drawn) can be attached. In particular, when measuring the bat swing in the batting mode or measuring the running speed of the runner in the short distance mode, it is necessary to install it at a certain height. It is preferable because it can be fixed.

  While the battery 31 is disposed at the rear end of the case body 10, the horn antenna 23 is disposed at the front portion 10b of the case body 10 and the tripod mounting portion 12g is provided at a position near the center of gravity where the weight balance between the battery and the horn antenna can be obtained. Thus, it is possible to easily perform the work of attaching the apparatus to a tripod or the like.
