Description

[Technical field]

[0001] The present disclosure relates to an electronic device having a lock lever. [Background technology]

[0002] There are many electronic devices that use a lock lever to lock the case or the battery cover. In this type of electronic device, the case or the battery cover is locked or unlocked by operating the lock lever. For example, Patent Document 1 describes a battery cover structure having a lock lever. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2008-181767 A Summary of the Invention [Problem to be solved by the invention]

[0004] The lock lever is biased in the lock direction by the biasing force of a coil spring or a leaf spring, and is set to the unlocked state when the user operates the lock lever in the unlock direction. Therefore, a coil spring or a leaf spring is required to obtain the biasing force.

[0005] This results in an increase in the number of parts, an increase in assembly steps, and an increase in the space required. Of these, the increase in the number of parts and the increase in the space required are undesirable for electronic devices that are required to be compact, such as portable electronic devices. Naturally, the increase in assembly steps is undesirable for all electronic devices.

[0006] The present disclosure has been made in consideration of the above points, and provides an electronic device that can supply a biasing force to a lock lever without increasing the number of parts, the number of assembly steps, and the occupied space. [Means for solving the problem]

[0007] One aspect of the electronic device of the present disclosure is to a housing case having a first case part and a second case part joined to each other and housing an electronic component; a packing made of an elastic body and provided in contact with a joint surface between the first case part and the second case part; a lock lever movable between a first position in a locked state and a second position in an unlocked state; having The packing has a lock lever biasing portion that biases the lock lever in a direction from the second position to the first position. Effect of the Invention

[0008] According to the present invention, it is possible to realize an electronic device that can supply a biasing force to a lock lever without increasing the number of parts, the number of assembly steps, and the occupied space. [Brief description of the drawings]

[0010] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.

[0011] <1> External appearance of medical telemeter Fig. 1 is a front view of a medical telemeter (hereinafter simply referred to as "telemeter") 10 according to this embodiment. In this embodiment, the up-down direction in Fig. 1 may be referred to as the up-down direction (±Y direction) of telemeter 10, the left-right direction in Fig. 1 as the left-right direction (±X direction) of telemeter 10, and the depth direction (±Z direction) of the paper surface in Fig. 1 as the front-back direction of telemeter 10.

[0012] As can be seen from FIG. 1, the front side of the telemeter 10 is provided with an LCD (Liquid Crystal Display) panel 11, an indicator 12, an operation unit 13, and the like.

[0013] 2 is a top side view of the telemeter 10. On the top side, a lead cord connector section 14 and an SpO2 input connector section 15 are provided. A lead cord extending from an electrode attached to the patient's chest is connected to the lead cord connector section 14. A cable of an SpO2 probe is connected to the SpO2 input connector section 15, and an SpO2 detection signal from the SpO2 probe is input.

[0014] 3 is a bottom side view of the telemeter 10. Power input connectors 16 and 17 are provided on the bottom side. A DC power output cable of an AC / DC adapter, for example, is connected to the power input connector 16. The power input connector 17 is a pogo pin connector, and is connected to a pogo pin 31 of a charging stand 30 in FIG. 6, which will be described later. Power input from the power input connectors 16 and 17 is supplied to a battery (not shown) built into the telemeter 10. This charges the battery.

[0015] A lock lever 18 is also provided on the lower side. The lock lever 18 locks a battery lid 19 provided on the back side of the telemeter 10. The lock lever 18 can be switched between a locked state and an unlocked state by a user's operation. Specifically, in the locked state, the lock lever 18 engages with one end of the battery lid 19 to lock the battery lid 19 to the case body of the telemeter 10. In contrast, when the lock lever 18 is set to the unlocked state by the user, the lock lever 18 is disengaged from the battery lid 19. By setting the lock lever 18 to the unlocked state, the user can remove the battery lid 19 and replace the battery.

[0016] Fig. 4 is a left side view of the telemeter 10. A power switch 20 is provided on the left side. Fig. 5 is a right side view of the telemeter 10.

[0017] FIG. 6 is a perspective view of the charging stand 30 of the telemeter 10, seen from obliquely above. The charging stand 30 has pogo pins 31. When the telemeter 10 is placed against the charging stand 30, the pogo pins 31 are electrically connected to the power input connector section 16, which is a pogo pin connector. The charging stand 30 is also provided with a power input connector section (not shown) to which, for example, a DC power output cable of an AC / DC adapter is connected, and a data input / output connector section (not shown). This allows the telemeter 10 to charge the battery and communicate data with an external device via the charging stand 30. The telemeter 10 is not only capable of inputting power via the power input connector section 17, but is also capable of inputting and outputting signals. This allows the telemeter 10 to transmit and receive signals to and from the external device via the charging stand 30, thereby enabling operation diagnosis using the external device.

[0018] The charging stand 30 is formed with an insertion portion 32 into which the lower portion of the telemeter 10 is inserted, and also with a protrusion 33 that engages with a recess (not shown) on the back surface of the telemeter 10. As a result, when the telemeter 10 is inserted, the charging stand 30 holds the telemeter 10 with the insertion portion 32 and the protrusion 33, thereby preventing the telemeter 10 from tilting or shifting upward (in the +Y direction). As a result, the reliability of the electrical connection between the pogo pin 31 and the power input connector portion 16 can be improved.

[0019] <2> circuit board structure Here, particularly characteristic portions of the circuit board structure of the telemeter 10 of this embodiment will be described.

[0020] 7 is a perspective view showing the main circuit board 40 and ECG processing unit 50 built into the telemeter 10. The main circuit board 40 is connected to the power input connector units 16, 17. Electronic components 42 (FIG. 14) such as an amplifier and a filter for power processing, a wireless module 41, etc. are mounted on the main circuit board 40.

[0021] The ECG processing unit 50 is connected to the connection pin 14a of the lead cord connector unit 14. The ECG processing unit 50 is also connected to the main circuit board 40. The ECG processing unit 50 performs measurement processing of an electrocardiogram (ECG) based on the potential input from the connection pin 14a of the lead cord connector unit 14. Specifically, the ECG processing unit 50 performs analog-to-digital conversion, ECG waveform formation processing, etc. The signal obtained by the ECG processing unit 50 is wirelessly transmitted to a central monitor or the like by the wireless module 41 of the main circuit board 40.

[0022] FIG. 8 is a development view for explaining the circuit board structure of the ECG processor 50. As shown in FIG.

[0023] The ECG processing unit 50 has a signal input board 51 on which a signal input unit is formed, and a plurality of circuit boards 52, 53, 54, 55 extending in all directions from the signal input board 51. The processing of the ECG processing unit 50 is distributed among the plurality of circuit boards 52 to 55.

[0024] The signal input board 51 is connected to the connection pin 14a of the induction cord connector portion 14. The connection pin 14a and the signal input board 51 are electrically connected by, for example, soldering.

[0025] Each of the circuit boards 52, 53, 54, and 55 has a flexible board 52a, 53a, 54a, and 55a, and is connected to the signal input board 51 via the flexible board 52a, 53a, 54a, and 55a. Also, connection parts 52b, 53b, 54b, and 55b are provided on the end side of each of the circuit boards 52, 53, 54, and 55. Furthermore, the ECG processing unit 50 has a connection connector part 57 connected to the main circuit board 40.

[0026] 9, 10 and 11 are diagrams for explaining the assembly procedure of the ECG processor 50. FIG.

[0027] As shown in the plan view of Fig. 9 and the perspective view of Fig. 10, first, a support member 56 is provided upright on a signal input board 51. The support member 56 is made of a non-conductive material. In the embodiment, the support member 56 is made of resin. The support member 56 has a box-like shape having a bottom surface, a top surface and four side surfaces as main surfaces.

[0028] 11, circuit boards 52, 53, 54, and 55 are arranged along the four side surfaces of support member 56. At this time, flexible boards 52a, 53a, 54a, and 55a are bent, so that circuit boards 52, 53, 54, and 55 can be easily arranged at predetermined positions on support member 56.

[0029] Furthermore, a plurality of engaging protrusions 56a are formed on the support member 56, and the engaging protrusions 56a engage with engaging holes in the circuit boards 52, 53, 54, and 55, thereby positioning and fixing the circuit boards 52, 53, 54, and 55 at predetermined positions on the support member 56. In other words, locking portions (engaging protrusions 56a) are formed on the plurality of main surfaces of the support member 56, and the plurality of circuit boards 52, 53, 54, and 55 constituting the circuit board group are each positioned and fixed at a predetermined position on the plurality of main surfaces of the support member 56 by the locking portions (engaging protrusions 56a).

[0030] As shown in Fig. 11, when the circuit boards 52, 53, 54, and 55 are arranged along the support member 56, the connection pins constituting the connection parts 52b and 53b of the circuit boards 52 and 53 stand in a direction parallel to the Y direction. As shown in Fig. 11, the connection pins are fitted into the connection holes that are the connection parts 54b and 55b of the circuit boards 54 and 55. Next, the connection pins and the connection holes are soldered. This electrically and mechanically integrates the circuit boards 52, 53, 54, and 55.

[0031] Next, the main circuit board 40 is connected to the connector unit 57. As a result, the ECG processing unit 50 inputs the cardiac potential from the signal input board 51, performs measurement processing of an electrocardiogram (ECG) using circuit boards 52, 53, 54, and 55, and outputs the processing results to the main circuit board 40.

[0032] As described above, the electronic device (telemeter 10) of this embodiment has a first circuit board (signal input board 51) on which a signal input section is formed, a support member 56 standing on the first circuit board, and a circuit board group consisting of multiple circuit boards 52, 53, 54, 55 each extending so as to expand from the first circuit board and arranged to cover support member 56.

[0033] In addition, in the electronic device of this embodiment, the multiple circuit boards 52, 53, 54, and 55 that constitute the circuit board group each have terminals (connection portions 52b, 53b, 54b, 55b) on their end sides, and the terminals of the multiple circuit boards 52, 53, 54, and 55 are connected to each other while being arranged to cover the support member 56.

[0034] In addition, in the electronic device of this embodiment, the circuit board group (circuit boards 52, 53, 54, 55) is connected to the first circuit board (signal input board 51) via flexible boards 52a, 53a, 54a, 55a, and the circuit board group (circuit boards 52, 53, 54, 55) is positioned so as to cover support member 56 by bending flexible boards 52a, 53a, 54a, 55a.

[0035] In the electronic device of the present embodiment, the support member 56 has a plurality of main surfaces, and the plurality of circuit boards 52, 53, 54, 55 constituting the circuit board group are arranged along the plurality of main surfaces of the support member 56, respectively.

[0036] In addition, in the electronic device of this embodiment, locking portions (engagement protrusions 56a) are formed on multiple main surfaces of support member 56, and multiple circuit boards 52, 53, 54, 55 that constitute the circuit board group are each positioned and fixed at predetermined positions on the multiple main surfaces of support member 56 by the locking portions.

[0037] In the electronic device of this embodiment, a lead cord for a cardiac potential is connected to the signal input section of the first circuit board (signal input board 51), and the group of circuit boards (circuit boards 52, 53, 54, 55) performs measurement processing of an electrocardiogram.

[0038] Here, in conventional medical telemeters that wirelessly transmit a patient's ECG, in general, many devices do not include an ECG processor in order to reduce the size of the device. In such medical telemeters, instead of including an ECG processor in the device body, an ECG processor is installed on the lead cord side, and the medical telemeter wirelessly transmits the signal processed by the ECG processor.

[0039] However, when such a configuration is adopted, it is necessary to use a lead cord dedicated to the telemeter. On the other hand, a vital sign monitor or the like has a built-in ECG processor, so a lead cord without an ECG processor can be used.

[0040] In this embodiment, the telemeter 10 is equipped with an ECG processor 50, so that a common lead code can be used with a vital sign monitor or the like.

[0041] However, simply providing an ECG processing unit would result in another problem of the telemeter becoming larger. In a vital sign monitor or the like, which is larger in device size than a telemeter, the ECG processing unit is often formed on a single circuit board. However, in a telemeter that is required to be compact, it is not preferable to adopt such a configuration. In this embodiment, by adopting the circuit board structure described above, it is possible to prevent the telemeter from becoming larger when an ECG processing unit is provided.

[0042] In the electronic device of this embodiment, the group of circuit boards (circuit boards 52, 53, 54, 55) extending out from the first circuit board (signal input board 51) are arranged in a box-like three-dimensional manner to cover the support member 56, thereby preventing the size of the entire device (the size of the telemeter 10) from increasing even if the area of ​​the circuit boards increases (i.e., even if ECG processing unit 50 is added).

[0043] Furthermore, when the multiple circuit boards 52, 53, 54, 55 are arranged three-dimensionally, the distance between the circuit boards 52, 53, 54, 55 is set to a predetermined distance or more by the support member 56, thereby ensuring the insulation distance. For example, the support member 56 can increase the creepage distance between resistors formed on the circuit boards 52, 53, 54, 55, thereby ensuring the insulation distance. In other words, the support member 56 has a function of arranging the multiple circuit boards 52, 53, 54, 55 three-dimensionally in a predetermined shape, and a function as a spacer.

[0044] <3> Mounting structure for display panel 11 12, 13, 14 and 15 are perspective views illustrating the mounting structure of the display panel 11. FIG.

[0045] 12 and 13, the display panel 11 is fitted into a holding member 60 made of resin. Fig. 12 is an exploded perspective view of the display panel 11 before it is fitted into the holding member 60, and Fig. 13 is a perspective view of the display panel 11 after it has been fitted into the holding member 60.

[0046] The display panel 11 fitted into the holding member 60 is disposed between the main circuit board 40 and the sub-circuit board 70, as shown in Figures 14 and 15. Figure 14 is an exploded perspective view of the display panel 11, the main circuit board 40, and the sub-circuit board 70 before they are joined together, and Figure 15 is a perspective view showing the state after the display panel 11, the main circuit board 40, and the sub-circuit board 70 are joined together.

[0047] When they are joined, the connector portion 43 provided on the main circuit board 40 and the connector portion (not shown) provided on the sub-circuit board 70 are connected. When they are joined, the holding member 60 is sandwiched between the main circuit board 40 and the sub-circuit board 70. The connector portion 43 is disposed on the periphery of the main circuit board 40, which allows the user to visually check whether the main circuit board 40 and the sub-circuit board 70 are securely connected. In order to prevent poor connection due to separation between the main circuit board 40 and the sub-circuit board 70, the two circuit boards 40, 70 are held down by the corners of the case, locking claws, or the like.

[0048] As described above, electronic components 42 such as an amplifier for power processing, a filter, an image processing module, and a wireless module 41 are mounted on the main circuit board 40. The sub-circuit board 70 is provided with a switch 71 and the like that is provided at a position corresponding to the operation unit 13 (FIG. 1) and is turned on and off in response to the operation of the operation unit 13. The flexible board 11a extending from the display panel 11 is connected to the main circuit board 40.

[0049] Furthermore, the sub-circuit board 70 has an opening 72 formed therein that is slightly larger than the outer size of the display panel 11. In other words, the sub-circuit board 70 has an opening 72 into which the display panel 11 can be fitted.

[0050] The position of the display surface of the display panel 11 protrudes slightly in the +Z direction from the sub-circuit board 70 through the opening 72. The position of the display surface of the display panel 11 may be the same position as the +Z direction surface of the sub-circuit board 70, or may be slightly recessed in the -Z direction from the +Z direction surface of the sub-circuit board 70. In short, the display panel 11 is disposed at a position where the display panel 11 and the sub-circuit board 70 at least partially overlap in the thickness direction (±Z direction).

[0051] This makes it possible to suppress the increase in thickness caused by providing the display panel 11 compared to a case in which the display panel 11 is attached to the +Z direction surface of the sub-circuit board 70 with double-sided tape or the like without forming the opening 72.

[0052] Furthermore, in the present embodiment, by disposing display panel 11 in the gap between main circuit board 40 and sub-circuit board 70, an increase in thickness due to display panel 11 is suppressed.

[0053] Here, electronic components 42 are mounted on the main circuit board 40, and a gap (e.g., about 4 to 5 mm) is generated between the main circuit board 40 and the sub-circuit board 70 according to the height of the electronic components 42. In the present embodiment, the display panel 11 is disposed in this gap to effectively utilize the gap and to prevent an increase in thickness due to the display panel 11.

[0054] In this embodiment, one reason for dividing the circuit board into the main circuit board 40 and the sub-circuit board 70 and arranging them in the stacking direction is that the size of the telemeter can be made smaller than that of a single circuit board. Another reason is that the main circuit board 40 and the sub-circuit board 70 can be used to realize an antenna for a wireless LAN (Local Area Network). Specifically, one of the main circuit board 40 and the sub-circuit board 70 functions as the antenna ground, and the other has a copper foil pattern formed thereon to obtain a desired resonance frequency. In other words, the telemeter 10 has a communication function and an antenna used therefor, and at least one of the first and second circuit boards functions as the antenna ground.

[0055] As described above, according to this embodiment, there are first and second circuit boards (main circuit board 40 and sub-circuit board 70) arranged in a stacking direction, and a display panel 11 arranged between the first and second circuit boards. Of the first and second circuit boards, the circuit board (sub-circuit board 70) arranged on the display surface side of the display panel 11 has a cutout portion (opening 72) formed therein into which the display panel 11 can be fitted, and the display panel 11 is arranged at a position where at least a portion of the display panel 11 overlaps in the thickness direction with the circuit board (sub-circuit board 70) in which the cutout portion (opening 72) is formed.

[0056] This makes it possible to realize a telemeter 10 in which an increase in the thickness of the device is suppressed even when the display panel 11 is included. In particular, when the display panel 11 is an LCD panel, the thickness of the display panel 11 including the backlight is about 2.5 mm. Therefore, for example, when the display panel 11 is attached to the sub-circuit board 70, the thickness of the device increases by about 2.5 mm compared to when the display panel 11 is not provided. In contrast, according to the configuration of this embodiment, the increase in the thickness of the device caused by the thickness of the display panel 11 can be suppressed, and when the above-mentioned LCD panel is adopted, for example, the thickness of the device can be practically reduced by about 1.8 mm.

[0057] In addition, compared to, for example, a case where the display panel 11 is attached onto the sub-circuit board 70, this is advantageous in terms of heat dissipation efficiency.

[0058] Furthermore, since the display panel 11 fits into the cutout portion (opening 72), it is supported by the circuit board (sub-circuit board 70), and misalignment in the XY directions is suppressed. Note that, in the embodiment, the cutout portion (opening 72) has a shape with four closed sides, but the cutout portion may have, for example, three of the four sides closed and one side open. For example, of the four sides of the opening 72 in FIG. 14, one side in the -X direction may be cut out so as to be open.

[0059] In addition, electronic components 42 are mounted on the opposing surfaces of at least one of the first and second circuit boards (main circuit board 40 and sub-circuit board 70), and a gap corresponding to at least the thickness of electronic components 42 exists between the first circuit board and the second circuit board, and display panel 11 is disposed across at least both this gap and opening 72.

[0060] This allows the gap between the first and second circuit boards (main circuit board 40 and sub-circuit board 70) to be effectively utilized, and makes it possible to suppress an increase in thickness due to display panel 11.

[0061] Furthermore, as can be seen from Fig. 14, the holding member 60 has an arm 61. SpO2 processing substrates 81, 82 are attached to this arm 61, as shown in Fig. 16 and Fig. 17. Fig. 16 shows an example in which a small-sized SpO2 processing substrate 81 is attached, and Fig. 17 shows an example in which a large-sized SpO2 processing substrate 82 is attached.

[0062] The SpO2 processing boards 81, 82 are detachably attached to the arm 61 using screws or the like. The SpO2 processing boards 81, 82 are electrically connected to the main circuit board 40 or the sub-circuit board 70 by connectors. In this embodiment, the SpO2 processing boards 81, 82 are held by the arm 61 of the holding member 60, so that the fixing strength can be increased compared to when the SpO2 processing boards 81, 82 are fixed only by connectors.

[0063] Here, when the SpO2 processing boards 81, 82 are directly attached to circuit boards such as the main circuit board 40 and the sub-circuit board 70, and the size of the SpO2 processing boards 81, 82 is changed, connection holes and the like must be formed in the circuit boards such as the main circuit board 40 and the sub-circuit board 70 in order to ensure the fixing strength, and this requires processing the circuit boards. In contrast, if an attachment section (arm 61) that allows the third circuit board (SpO2 processing boards 81, 82) to be detachably attached is provided in the holding member 60 as in this embodiment, the fixing strength of the third circuit board (SpO2 processing boards 81, 82) can be increased without processing the circuit board.

[0064] In addition, the main circuit board 40 is formed with a notch 44 for avoiding interference with the SpO2 processing boards 81 and 82.

[0065] <4> Lock lever Next, the configuration of the lock lever 18 of this embodiment will be described with reference to FIGS.

[0066] Fig. 18 is a perspective view of the telemeter 10 when the lock lever 18 is in the locked state, and Fig. 19 is a perspective view of the telemeter 10 when the lock lever 18 is in the unlocked state. Fig. 20 is an enlarged perspective view of the lower case 10a when the lock lever 18 is in the unlocked state.

[0067] 18 and 19, the case of the telemeter 10 is roughly divided into a main case 10c, a lower case 10a, and an upper case 10b. The upper case 10b and the lower case 10a are fitted into the main case 10c from the top and bottom (±Y direction). Here, packing is provided on the joint surfaces between the upper case 10b and the lower case 10a and the main case 10c, so that the upper case 10b and the lower case 10a and the main case 10c are joined in a watertight state.

[0068] In addition, a battery lid 10d as shown in FIG. 21 is removably attached to the back side of the telemeter 10. A packing 91 is provided on the edge of the battery lid 10d. When the lock lever 18 is in the locked state, the battery lid 10d is locked by the lock lever 18. In contrast, when the user operates the lock lever 18 to the unlocked state, the lock of the battery lid 10d by the lock lever 18 is released. This makes the battery lid 10d removable from the main case 10c, and the user can remove the battery lid to replace the battery, etc.

[0069] 22 to 24 are diagrams showing the configuration of the back side of the lower case 10a. Fig. 22 is an exploded perspective view showing the state in which the packing 92 and the lock lever 18 are removed from the lower case 10a, Fig. 23 is a perspective view showing the state in which the packing 92 and the lock lever 18 are attached to the lower case 10a, and Fig. 24 is a plan view.

[0070] The packing 92 extends along the edge of the lower case 10a and comes into contact with the joint surfaces of the main case 10c and the lower case 10a when the lower case 10a is fitted into the main case 10c, thereby joining the main case 10c and the lower case 10a in a watertight manner.

[0071] The lock lever 18 has a rotating shaft 18a and is rotatably attached to the lower case 10a via the rotating shaft 18a. The lock lever 18 also has a locking claw 18b, and when the lock lever 18 is in the first rotation position which is the locked state, the locking claw 18b comes into contact with the back surface of the battery lid 10d to lock the battery lid 10d.

[0072] The packing 92 has a packing body 90a extending along the edge of the lower case 10a and a lock lever biasing portion 92b formed integrally with the packing body 90a. The lock lever 18 is also formed with a contact portion 18c that contacts the lock lever biasing portion 92b.

[0073] As can be seen from FIG. 24, when the lock lever 18 is attached to the lower case 10a, the abutment portion 18c is adjacent to the lock lever biasing portion 92b.

[0074] Figures 25 and 26 are cross-sectional views taken along the line AA in Figure 24. Figure 25 is a cross-sectional view when the lock lever 18 is in a first rotation position in a locked state, and Figure 26 is a cross-sectional view when the lock lever 18 is in a second rotation position in an unlocked state.

[0075] When the user rotates the lock lever 18 from the locked state shown in Fig. 25 to the unlocked state shown in Fig. 26, the abutment portion 18c deforms the lock lever biasing portion 92b. As a result, in the state shown in Fig. 26, a biasing force in the direction of arrow R is applied to the abutment portion 18c by the elastic force of the lock lever biasing portion 92b. Therefore, when the user releases the lock lever 18, the lock lever 18 returns to the locked state shown in Fig. 25.

[0076] When the lock lever 18 is set to the unlocked state, the locking claw 18b of the lock lever 18 moves away from the battery lid 10d, and the battery lid 10d is released from the locking of the battery lid 10d. At this time, the elastic force of the packing 91 allows the battery lid 10d to easily come off from the main case 10c.

[0077] As described above, the telemeter 10 of this embodiment has a first case part (main case 10c) and a second case part (lower case 10a) joined together, a housing case for housing electronic parts, a gasket 92 made of an elastic body and provided in contact with the joining surfaces of the first case part and the second case part, and a lock lever 18 that is rotatable between a first rotation position which is a locked state and a second rotation position which is an unlocked state, and the gasket 92 has a lock lever biasing portion 92b that biases the lock lever 18 in the direction from the second rotation position to the first rotation position.

[0078] This makes it possible to supply a biasing force to the lock lever without increasing the number of parts, the number of assembly steps, or the space required, compared to the case where a coil spring, leaf spring, or the like is provided.

[0079] In this embodiment, a U-shaped notch 92c is formed in the lock lever biasing portion 92b, which increases the elastic force when the abutting portion 18c presses the lock lever biasing portion 92b.

[0080] <4> Other embodiments The above-described embodiment is merely an example of the embodiment of the present invention, and the technical scope of the present invention should not be interpreted as being limited by the embodiment. In other words, the present invention can be embodied in various forms without departing from the gist or main characteristics of the present invention.

[0081] Items in the above embodiment <2> In the above description, the multiple circuit boards extending so as to spread out from the first circuit board (signal input board 51) are four circuit boards 52, 53, 54, 55, and all of these four circuit boards 52, 53, 54, 55 cover the support member 56 and are mechanically and electrically integrated by the terminals on the end side (connecting portions 52b, 53b, 54b, 55b), but this is not limiting. For example, the multiple circuit boards extending so as to spread out from the first circuit board (signal input board 51) may be five, four of which cover the support member 56 and are mechanically and electrically integrated by the terminals on the end side, and the remaining one may be directly connected to the main circuit board 40 without being integrated.

[0082] In the above-described embodiment, the circuit board structure, the display panel mounting structure, and the configuration for applying a biasing force to the lock lever of the present disclosure have been described as being applied to a telemeter, but the present disclosure is not limited to this and can be widely applied to various electronic devices. For example, <2> Although the circuit board structure of the present disclosure has been described above as being applied to the ECG processing unit 50, it can also be applied to circuits that perform processing other than ECG processing.

[0083] Also, items <4> Although the configuration of the present disclosure for applying a biasing force to the lock lever has been described above as being applied to the housing case of the telemeter 10, it can also be applied to the housing case of other electronic devices. In addition, the lock lever is not limited to the lock lever that locks the battery cover 10d. The configuration of the present disclosure is useful for electronic devices that require miniaturization.

[0084] In the above embodiment, the lock lever is a rotating type lock lever 18, but the configuration of the present disclosure is also applicable to a case where a slide type lock lever is used. In short, the electronic device has a packing made of an elastic body and provided in contact with the joint surface of the first case part and the second case part, and a lock lever that is movable between a first position in a locked state and a second position in an unlocked state, and the packing has a lock lever biasing part that biases the lock lever from the second position to the first position. For example, the lock lever may be slidable in the ±Y direction in FIG. 21, and the lock lever biasing part may have a surface perpendicular to the ±Y direction and may apply a biasing force to the lock lever by abutting against the lock lever on this surface.

[0085] However, as in the above-described embodiment, if the lock lever 18 is rotatable between a first rotation position in a locked state and a second rotation position in an unlocked state, and the lock lever biasing portion 92b is configured to bias the lock lever 18 in a direction from the second rotation position to the first rotation position, the abutting portion 18c of the lock lever 18 presses the lock lever biasing portion 92b in a direction (±Z direction) perpendicular to the pressing direction (±Y direction) of the packing (packing body 90a) at the joining surface between the first case part (main case 10c) and the second case part (lower case 10a). As a result, the configuration of the embodiment is advantageous in that a biasing force can be supplied to the lock lever 18 without affecting the pressing force of the packing (packing body 90a) at the joining surface, that is, without affecting the sealing effect of the packing (packing body 90a) at the joining surface.
