  "abstract": "A battery holding mechanism is adapted to selectively accommodate a first battery having a larger outer diameter, or two second batteries each having a smaller outer diameter. The battery holding mechanism includes a battery holder and a resilient positioning member. The battery holder defines therein an installation space configured to permit only the first battery or only the second batteries to be installed. When the first battery is installed, the first battery is positioned by the resilient positioning member. When the second batteries are installed, the second batteries are positioned by the resilient positioning member in a juxtaposed manner.",
  "claims": [
    "1. A battery holding mechanism which is for being built in a wireless transmitter and receiver device, and which is adapted to selectively accommodate a first battery having a first outer diameter, or two second batteries each having a second outer diameter smaller than the first outer diameter, said battery holding mechanism comprising: a battery holder defining therein an installation space which extends in an X direction and which is configured to selectively permit only the first battery to be axially installed in the installation space in the X direction, or permit only the second batteries to be axially installed in the installation space in the X direction in a juxtaposed manner; and a resilient positioning member which is connected to said battery holder, and which is configured such that when the first battery is installed in the installation space, said resilient positioning member is disposed to resiliently abut against the first battery in a Z direction orthogonal to the X direction to thereby position the first battery within said battery holder, and such that when the second batteries are installed in the installation space, said resilient positioning member is disposed to resiliently abut against a first one of the second batteries in the Z direction to force the first one of the second batteries into abutment against a second one of the second batteries to thereby position the second batteries within said battery holder in the juxtaposed manner.",
    "2. The battery holding mechanism according to claim 1, wherein said battery holder includes a first body segment and a second body segment which are displaced from each other in a Y direction orthogonal to both the X and Z directions, wherein said first body segment has a first abutment surface configured for selectively abutting against an outer periphery of the first battery or an outer periphery of the second one of the second batteries, wherein said second body segment has a second abutment surface configured for abutting against an outer periphery of the first one of the second batteries, wherein said first and second abutment surfaces define a level difference to permit axles of the second batteries installed in said installation space to be in different levels in the Z direction, and wherein said resilient positioning member is spaced apart from said first and second body segments in the Z direction.",
    "3. The battery holding mechanism according to claim 2, wherein a distance between said resilient positioning member and said second abutment surface is smaller than a distance between said resilient positioning member and said first abutment surface, and wherein said resilient positioning member is disposed to selectively permit the first battery to be resiliently abutted between said resilient positioning member and said first abutment surface or permit the first one of the second batteries to be resiliently abutted between said resilient positioning member and said second abutment surface.",
    "4. The battery holding mechanism according to claim 2, wherein said battery holder further includes a stop segment which is connected to a side of said first body segment opposite to said second body segment in the Y direction, and which is configured for selectively abutting against the first battery or the second one of the second batteries.",
    "5. The battery holding mechanism according to claim 2, wherein said resilient positioning member includes two connection segments which are respectively connected to said battery holder and which are spaced apart from each other in the X direction, and an abutment segment which is connected between said connection segments, and which is arc-shaped and is curved toward said first and second body segments for selectively and resiliently abutting against the outer periphery of the first battery or the outer periphery of the first one of the second batteries.",
    "6. The battery holding mechanism according to claim 5, wherein said abutment segment includes a first positioning region which is spaced apart from said first abutment surface in the Z direction, and which is configured to permit the first battery to be resiliently abutted between said first positioning region and said first abutment surface, and a second positioning region which is connected and opposite to said first positioning region in the Y direction, and which is spaced apart from said second abutment surface in the Z direction, said second positioning region being configured to permit only one of the second batteries to be resiliently abutted between said second positioning region and said second abutment surface.",
    "7. The battery holding mechanism according to claim 5, wherein each of said first and second positioning regions is arc-shaped.",
    "8. The battery holding mechanism according to claim 2, wherein said battery holder further includes two end wall portions which are spaced apart from each other in the X direction, each of said end wall portions being connected to both said first and second body segments, said two end portions and said first and second body segments cooperatively defining said installation space therebetween, said battery holding mechanism further comprising a pair of first electrodes which are mounted respectively on said end wall portions in said installation space to be spaced apart from each other in the X direction, and a pair of second electrodes which are mounted respectively on said end wall portions in said installation space to be spaced apart from each other in the X direction, and which are respectively spaced apart from said first electrodes in the Y direction."

  "description_excerpt": "The disclosure relates to a battery holder, more particularly to a battery holding mechanism for being built in a wireless transmitter and receiver device.\n\nWireless transmitter and receiver devices are currently available in two designs for two different kinds of batteries. One kind of the batteries are disposable batteries such as AA batteries and the other kind of the batteries are rechargeable lithium batteries, such as ICR-18500 batteries. Because the two kinds of batteries have different sizes, one wireless transmitter and receiver device may be suitable for being installed with only one kind of the batteries. A user may want to select different kinds of the batteries for different purposes and occasions. Therefore, manufacturers must make the wireless transmitter and receiver devices in the two different designs, and apply for wireless regulatory certification for both the two designs. As such, the conventional wireless transmitter and receiver devices may have a relatively high cost in manufacturing and selling, and may be relatively inconvenience to the user.\n\nTherefore, an object of the disclosure is to provide a battery holding mechanism for being built in a wireless transmitter and receiver device, which overcomes at least one drawback of the prior art mentioned above.\n\nAccording to the disclosure, a battery holding mechanism is for being built in a wireless transmitter and receiver device, and is adapted to selectively accommodate a first battery having a first outer diameter, or two second batteries each having a second outer diameter smaller than the first outer diameter.",
