The apparatus main body 50 is provided with a heart rate sensor connection terminal (not shown), and a signal indicating the heart rate detected by the heart rate sensor 22 is supplied to the apparatus main body 50 via a heart rate sensor cord (not shown) connected thereto. The In addition to the power switch 55 described above, the operator group 23 includes first and second levers 52A and 52B, which are tilt switches, and a push-down switch 53 (see FIGS. 2 and 3).

  As shown in FIGS. 4 and 5, the pedestal 41 is configured integrally with a bottom plate portion 42 and side plate portions 43 on the shoulder side and the hand side, and has a U-shape that is open upward as viewed from the rear side (FIG. 4). (See (b)). A locking slit 44 is formed in the side plate portion 43 near the center in the longitudinal direction.

  As shown in FIG. 4B, the device main body 50 has a rectangular shape that is substantially the same width as the pedestal 41 when viewed from the rear side, and has a substantially trapezoidal shape when viewed from the shoulder side. The mounting surface 50h, which is the bottom surface of the apparatus main body 50, and the pedestal 41 have the same length in the longitudinal direction. The narrow side portions (the mounting surface 50h side) of the side surface 50f on the shoulder side and the side surface 50i on the hand side of the apparatus main body 50 have dimensions that fit between the side plate portions 43 of the base 41. In addition, a locking piece 51 having a fitting shape with respect to the locking slit 44 of the pedestal 41 is integrally formed in the narrow portion.

  When the narrow portion of the apparatus main body 50 is fitted between the side plate portions 43 of the pedestal 41 and the mounting surface 50h is brought into contact with the bottom plate portion 42, the locking piece 51 is fitted into the locking slit 44. Combined. Thereby, the apparatus main body 50 is fixed to the pedestal 41. On the other hand, when the apparatus main body 50 is moved so as to be extracted in the front side direction and the engagement between the locking slit 44 and the locking piece 51 is released, the apparatus main body 50 is removed from the base 41. As will be described later, since the base 41 is always fixed to the mounting belt 30, the apparatus main body 50 can be attached to and detached from the mounting belt 30 by these operations.

  In a state where the apparatus main body 50 is fixed to the base 41, the front end 41a and the rear end 41b of the base 41, and the front end 50a and the rear end 50b on the mounting surface 50h side of the apparatus main body 50 are Each is united in a fixed state.

  As shown in FIG. 3, the power switch 55 is disposed on the front side and the shoulder side in the surface 50 e of the apparatus main body 50. The power switch 55 does not protrude from the surface 50e to prevent erroneous operation, and is flush with the surface 50e in a non-operation state. The display screen 59 is disposed mainly from the center in the longitudinal direction to the rear half in the surface 50e. The first and second levers 52 </ b> A and 52 </ b> B and the push-down switch 53 protrude from the surface 50 e of the apparatus main body 50. The first and second levers 52 </ b> A and 52 </ b> B are disposed in front of and behind the display screen 59 in close proximity to the display screen 59, and face each other across the display screen 59.

  The first and second levers 52A and 52B are provided to project obliquely forward and obliquely rearward (see FIGS. 4A and 5), respectively, in the width direction (shoulder side to hand side direction) of the surface 50e. long. Further, in any case, a force is applied to the display screen 59 side, so that the display screen 59 side is tilted (to an extent that the display screen 59 is substantially vertical). This is the movement when the first and second levers 52A and 52B are operated. On the other hand, when the operation is released, the first and second levers 52A and 52B are biased in a direction to fall to the opposite side of the display screen 59 by a spring or the like, and return to the original position by themselves. The first and second levers 52A and 52B can be individually operated.

  The push switch 53 is disposed close to the front side of the first lever 52A. The push switch 53 is a push type switch. In the shoulder side direction of the push switch 53, a finger hook portion 54 is provided so as to be connected to the push switch 53. The push switch 53 and the finger-hanging portion 54 are long in the width direction of the surface 50e, and both form an integral rectangle when viewed from the front side. Both projecting heights are also the same, and they are visually recognized as if they were integrated in design.

  When the wearable electronic device 100 is operated with the left arm 25 being worn, the wearable electronic device 100 is operated with the right hand. In this case, as shown in FIG. 3, when the thumb 26 is placed on the finger rest 54 and brought into contact with or close to the first lever 52A, and the index finger 27 is brought into contact with or close to the second lever 52B, Is easier to do.

  First, the distance between the first and second levers 52A and 52B is set to be approximately the same as the distance between the index finger and the thumb in the average user's natural operation standby state. Since the thumb 26 is on the finger-hanging portion 54, it is easy to shift to either the pressing operation of the pressing switch 53 or the tilting operation of the first lever 52A. It is also easy to tilt the second lever 52B with the index finger 27. Simultaneous operation in the direction in which the first and second levers 52A and 52B are sandwiched between the thumb 26 and the index finger 27 is also easy, and one-handed operation is easy. In addition, the finger-hanging portion 54 performs a protection function that prevents the thumb 26 from being operated without intention of the push switch 53 or the first lever 52A when the thumb 26 is locked.

  Changes in the display contents and setting contents of the display screen 59 due to the operation will be described later with reference to FIGS. 6 and 7, but in typical operations, device settings relating to music reproduction using the display of the display screen 59 are made. For example, the push switch 53 functions as a switch that advances processing and screen display to the next layer or another menu when pressed, and when pressed for a predetermined second (for example, 2 seconds) or longer, On the contrary, it functions as a return switch that returns one level. The first and second levers 52A and 52B are used to select items displayed on the display screen 59.

  For example, as shown in FIG. 3, the music name of the reproduction candidate is displayed on the display screen 59 using the push switch 53. The color of the song name 59a (for example, “GHIJKL”) that is currently a candidate is shown inverted. Each time one of the first and second levers 52A and 52B is tilted once, the candidate songs to be reversed move to the rear side and the front side, respectively. When the first and second levers 52A and 52B are tilted at substantially the same time, the music that is a candidate at that time is determined as the playback music and playback is started. Note that the function of each switch changes due to the mode switching, and for example, not only functions relating to musical tone reproduction, such as changes in volume and tone, but also operations relating to fitness management and operations such as pronunciation processing can be performed.

  Further, the user 24 not only performs the visual operation, but also determines the position of the thumb 26 based on the position of the finger grip 54, and further naturally determines the position of the index finger 27, and shifts to an operation standby state without visual recognition. can do. If the operation is simple, such as changing the volume or skipping music, the operation can be performed without looking at the operator or the display screen 59.

  Next, the configuration of the wearing belt 30 and related parts will be described. As shown in FIG. 4A, the mounting belt 30 includes a first belt portion 31, a second belt portion 32, a third belt portion 33, and a ring member 36. Each of the first to third belt portions 31 to 33 is configured in a belt shape having the same width using a flexible member such as resin or cloth as a base material.

  The bottom plate portion 42 of the base 41 is fixed to the third belt portion 33. The fixing method with respect to the 3rd belt part 33 of the base 41 is not ask | required, and attachment or detachment may be sufficient. Further, at least the first end portion 33a on the front side and the second end portion 33b on the rear side of the third belt portion 33 are substantially fixed to the front end portion 41a and the rear end portion 41b of the base 41, respectively. The intermediate portion between the first end portion 33a and the second end portion 33b may not be fixed to the pedestal 41.

  As shown in FIGS. 2 and 4A, the first end portion 31a of the first belt portion 31 and the first end portion 32a of the second belt portion 32 are connected to the first belt portion 33 at the junction point Pa. It is in a fixed state with respect to the end portion 33a. Further, the second end portion 31b of the first belt portion 31 is fixed to the rear end portion 41b of the base 41 at the joining point Pb together with the second end portion 33b of the third belt portion 33.

  Actually, in the present embodiment, the first to third belt portions 31 to 33 are integrally formed as a single band connected to each other, and the first end portion 33a is connected to the first end portion 31a and the joining point Pa. It is fixed to the first end 32a. However, the first to third belt portions 31 to 33 may be in a fixed state as described above after any or all of them are configured separately. When the first to third belt portions 31 to 33 are configured separately, the first end portions 31 a, 32 a, and 33 a are front end portions 41 a of the base 41 that are fixed to the front end portion 50 a of the apparatus main body 50. As long as it is fixed. The second end portions 31 b and 33 b may be fixed to the rear end portion 41 b of the base 41 that is fixed to the rear end portion 50 b of the apparatus main body 50.

  The first belt portion 31 covers the surface 50e of the apparatus main body 50, and the total length from the first end 31a to the second end 31b is from the front end 41a of the base 41 to the front side surface of the apparatus main body 50. The outer dimension is set to be longer than 50j, the surface 50e, the rear side surface 50g and the rear end portion 41b. The ring member 36 is engaged between the first end 31a and the second end 31b. As shown in FIG. 3, the ring member 36 has an insertion part 36a. The first belt portion 31 is inserted into the insertion portion 36a before the first end portion 33a is fixed to the first end portion 31a and the first end portion 32a, so that the ring member is inserted into the first belt portion 31. 36 is engaged.

  As shown in FIGS. 2 and 3, the first belt portion 31 has a window portion 31c. When the wearable electronic device 100 is attached, the display screen of the surface 50e is displayed from the window portion 31c. 59 and the components of the operator group 23 (first and second levers 52A and 52B, the push switch 53, etc.) are exposed. Therefore, there is no hindrance to operation and visual recognition of the operator group 23. Since the first end portion 31a of the first belt portion 31 is fixed to the front end portion 41a of the pedestal 41, an alignment function for positioning the window portion 31c at an appropriate position with respect to the surface 50e is performed.

  When the wearable electronic device 100 is worn on the arm 25, as shown in FIG. 2, the second end portion 32b of the second belt portion 32 is connected to the ring member 36 on the bottom side (mounting surface 50h side) of the device body 50. Is inserted through the insertion portion 36a and folded. A pair of surface fasteners 35A and 35B are provided on the surfaces of the second belt portion 32 facing each other by folding back (see FIGS. 2, 4A, and 5). By combining the two surface fasteners 35A and 35B, the second belt portion 32 is stably fixed in the folded state. The hook-and-loop fasteners 35A and 35B are not particularly limited as long as they can be repeatedly fixed and detached from each other.

  In the state where the wearable electronic device 100 is worn on the arm 25, as shown in FIGS. 2 and 5, the portion of the first belt portion 31 from the second end portion 31 b to the ring member 36 and the third belt portion 33. (Or, the mounting surface 50h of the apparatus main body 50) and the portion of the second belt portion 32 from the first end 32a to the ring member 36 form an annular mounting portion S2. In a specific mounting operation, the arm 25 is wound around the second belt portion 32, the second end portion 32b is inserted through the ring member 36 and folded back, and the second end portion 32b is pulled so as to have an appropriate tightening strength. After that, the surface fasteners 35A and 35B are fixed together. Thereby, the circumference | surroundings of the arm 25 are wound around annular mounting part S2. The apparatus main body 50 is protected from external force, is prevented from falling off, and is improved in appearance.

  In this mounted state, the first belt portion 31 is in close contact with the front side surface 50j of the apparatus main body 50, the front end portion 50c on the surface 50e side of the apparatus main body 50, and the surface 50e (see FIG. 5). An annular portion S <b> 1 is formed between the rear side surface 50 g of the apparatus main body 50 and the double portion of the first belt portion 31. The annular portion S <b> 1 is a triangular annular portion that connects the rear end portion 50 d, the rear end portion 50 b, and the ring member 36 on the surface 50 e side of the apparatus main body 50. When the apparatus main body 50 receives an external force from the rear end side, the annular portion S1 performs a buffer function.

  FIG. 6 is a flowchart of the main process. This process starts when the power switch 55 is turned on and is executed by the CPU 11.

  First, initialization is executed, that is, execution of a predetermined program is started, initial values are set in various registers, and initial setting is performed (step S101). Next, any operation of the operator group 23 is detected (step S102), and only when there is an operation, the operator corresponding process of FIG. 7 described later is executed (step S103). Next, processing such as performance is executed (step S104), and the process returns to step S102. In this performance processing, the selected music piece is played back in the music playback mode. In other modes, processing corresponding to the mode (display in fitness management, etc.) is executed.

  FIG. 7 is a flowchart of the operator handling process executed in step S103 of FIG. First, when there is an operation on the first lever 52A, the item in the selected state on the display screen 59 (see FIG. 3) is moved to the second lever 52B side (rear side) (steps S201 → S202 → S204). However, if the second lever 52B is operated within t seconds (for example, 0.5 seconds) after the first lever 52A is present, it is determined that the intention is to operate both levers 52A and 52B simultaneously. Therefore, the currently selected item is set in the device (steps S201 → S202 → S203).

  The same applies when the second lever 52B is operated first. When the second lever 52B is operated alone, the selected item is moved to the first lever 52A side (front side) (steps S205 → S206 → S208). However, if the levers 52A and 52B are operated simultaneously, the currently selected item is set in the device (steps S205 → S206 → S207).

  If it is a mode in which music selection is performed, the music set in steps S203 and S208 is reproduced in step S104 in FIG.

  In step S209, when there is a “return switch operation”, that is, when the push switch 53 is continuously pressed for a predetermined time or more, the display on the display screen 59 and the processing contents are returned to the previous display or hierarchy ( Steps S209 and S210). On the other hand, in the case of “advance switch operation” in which the push switch 53 is pressed within a predetermined time, the display on the display screen 59 and the processing contents are advanced to the next display or hierarchy (steps S211 and S212).

  Next, other processing is executed (step S213), and this processing ends. Here, in the other processing, for example, processing such as turning off the power switch 55 and switching modes is performed. The mode is switched by a predetermined combination operation of the first and second levers 52A and 52B and the push switch 53.

  According to the present embodiment, by inserting the second belt portion 32 through the insertion portion 36a of the ring member 36 and turning it back, the annular attachment portion S2 is formed, and the attachment type electronic device 100 is easily attached to the arm 25. (See FIGS. 2 and 5). In particular, since the annular portion S1 is formed on the rear end side by the rear side surface 50g of the device main body 50 and the first belt portion 31, the impact from the rear end side of the device main body 50 is absorbed by the annular portion S1. Thus, the apparatus main body 50 can be effectively protected from an external force from the outside.

  Further, if the second belt portion 32 is tightened, the first belt portion 31 strongly presses the device main body 50 from the front side, so that the device main body 50 is unlikely to fall off. On the other hand, if the second belt portion 32 is loosened, a gap is generated between the first belt portion 31 and the apparatus main body 50, and the apparatus main body 50 can be easily detached from the base 41. In addition, the mounting belt 30 can be composed of a single band, and it is not necessary to provide a bag-like holding portion, and the configuration is simple. Therefore, while the configuration of the mounting belt 30 is simple, it is possible to prevent the apparatus main body 50 from falling off due to an external force and to facilitate the attachment / detachment work of the apparatus main body 50. Furthermore, the appearance can be improved as compared with the configuration in which the apparatus main body 50 protrudes and is exposed.

  Further, according to the present embodiment, since the device setting using the display screen 59 can be performed by operating the first and second levers 52A and 52B projecting at positions facing each other across the display screen 59, the screen It is possible to facilitate the setting operation using the display.

  In addition, since the finger hook portion 54 is connected to the push switch 53, the standby position of the finger before the operation can be easily determined, and the operation can be further facilitated. Moreover, when the device setting using the display screen 59 is performed with the thumb 26 placed on the finger rest 54, the amount of displacement of the thumb 26 for operating the first lever 52A and the finger rest 54 may be small. Since both operations can be arbitrarily performed while the center of gravity of the thumb 26 is placed on the finger rest 54, the setting operation can be performed very smoothly.

  FIG. 8 is a view of a wearable electronic device that employs a wearable belt according to a modification of the present embodiment as viewed from the shoulder side. The mounting belt 30 according to this modification is obtained by eliminating the third belt portion 33 and providing a connecting portion 133 instead of the configuration shown in FIGS. Other configurations are completely unchanged.

  That is, the second end portion 31b of the first belt portion 31 is fixed to the rear end portion 41b of the base 41 that is fixed to the rear end portion 50b of the apparatus main body 50, and the first and second belt portions. The first end portions 31 a and 32 a of the main body 31 and 32 are fixed to the front end portion 41 a of the base 41 fixed to the front end portion 50 a of the apparatus main body 50 through the connection portion 133.

  In this configuration, since the third belt portion 33 does not exist, the bottom plate portion 42 of the pedestal 41 is one of the annular mounting portions S2 (see FIGS. 2 and 5) when the mounting type electronic device 100 is mounted on the arm 25. A part is formed, and directly contacts the arm 25. Further, the formation of the annular portion S1 is the same as in the examples of FIGS. Therefore, also in this modified example, the same effects as the configurations of FIGS. 1 to 5 can be obtained.

  In the present embodiment, the device main body 50 is illustrated as being fixed to the mounting belt 30 via the pedestal 41, but the effect of making the device main body 50 removable from the mounting belt 30 is unnecessary. Alternatively, a configuration in which the music playback device 40 is directly fixed to the mounting belt 30 may be employed.

  In addition, the insertion part 36a (refer FIG. 3) of the ring member 36 does not need to be a perfect cyclic | annular form, A cut may be provided in a part and it may comprise it from the 1st belt part 31 so that attachment or detachment is possible.

  Note that the rear side surface 50g and the front side surface 50j (see FIG. 4A) of the apparatus main body 50 do not have to be inclined and may be surfaces perpendicular to the surface 50e.

  The above description is just an example of how the first and second levers 52A and 52B are operated and what device settings are made. For example, the first and second levers 52 </ b> A and 52 </ b> B may be configured such that device settings can be performed by operating only one of them. Alternatively, the contents that can be set individually or in combination may be changed. The allocation function may be changed depending on the mode. These facilitate various settings.

  Note that the direction when the arm 25 is passed through the mounting belt 30 may be opposite to that illustrated. Moreover, the fixing direction of the mounting belt 30 with respect to the music playback device 40 in the longitudinal direction of the music playback device 40 may be opposite to that illustrated.
