  By the way, as described above, many portable terminal holders are equipped with a mechanism for detecting charging with a button, a switch, or the like when a portable terminal is mounted or the like and starting charging or the like. However, for example, very few devices have a mechanism for converting and transmitting a pressing force when pressing a push button or the like provided on the holder side into a force for pressing a push button switch on a portable terminal. .

  In particular, when the portable terminal is mounted on the holder, the distance between the pushing direction of the push button switch provided on the side surface of the casing of the portable terminal and the pushing direction of the push button provided on the holder When the relationship is substantially perpendicular, a special mechanism is required to convert and transmit the pressing force of the push button of the holder to the force of pressing the push button switch of the portable terminal.

  That is, as the special mechanism, the holder is provided with a lever having a hinge that transmits a pressing force in a direction substantially perpendicular to the pressing direction of the push button, such as a so-called piano key pressing mechanism. There is a need for a mechanism or a mechanism that allows the push button and the keystroke having the linear motion guides to move in a perpendicular direction via the cam.

  Here, in the case of the structure according to the former piano key keying mechanism, in order for the mechanism to function effectively, a sufficient distance must be ensured between the hinge part of the lever mechanism, the push button, and the keying part. However, a holder for a mobile terminal such as a mobile phone terminal is generally required to be small, and due to restrictions on the design of the holder, a sufficient distance for realizing the mechanism cannot be secured. May end up.

  In the case of the structure using the latter cam, the requirement for securing the distance as in the former can be ignored, but the sliding friction loss between the push button and the keystroke and the linear motion guide and the loss due to the cam mechanism (force Therefore, when the push button is pushed in, a large pressing force is required, and the feeling during pushing is also deteriorated.

  The present invention has been proposed in view of such circumstances, and when the mobile terminal is mounted, the pressing direction of the terminal-side push button provided on the side of the casing of the mobile terminal and the When the relationship between the push-in direction of the holder-side push button provided on the holder is substantially perpendicular, the structure does not increase in size, and when the holder-side push button is pushed in, a large push An object of the present invention is to provide a holder for a portable terminal that is provided with a mechanism for converting and transmitting a pressing force that does not require a force and that also has a good feel when pressed.

  The portable terminal holder of the present invention includes a push direction of the terminal push button provided on the side surface of the case of the portable terminal and a push of the holder push button provided on the holder when the portable terminal is placed. A holder for a portable terminal in which the relationship between the direction and the direction of the holder is substantially a right angle, a holder push button, a rotation axis substantially perpendicular to the pressing direction of the holder push button, The cam surface is formed integrally with a cam surface whose surface is inclined with respect to the pressing direction and whose inclined surface is a surface facing the pressing direction of the terminal push button. A button / cam portion for moving the rotary shaft in the turning direction of the turning shaft, a turning shaft substantially perpendicular to the turning shaft of the button / cam portion, a sliding contact portion slidably contacting the cam surface, and turning The keystroke part that moves according to the rotation of the shaft is integrated. And a formed keying hinge portion, the keying portion of the key depression hinge portion, by made by arranging the phase position corresponding to the terminal push button of the portable terminal, to solve the problems described above.

  That is, according to the present invention, the pressing direction and the pressing force of the holder push button are converted into the pressing direction and the pressing force of the terminal push button of the mobile terminal through the rotation of the cam surface. Since the friction loss is very small, it is possible to push the push button with a smaller pressing force than, for example, a cam mechanism using a linear motion guide.

  In the present invention, the portable terminal is mounted by converting the pressing direction and pressing force of the holder push button into the pressing direction and pressing force of the terminal push button of the portable terminal through rotation of the cam surface. In the state, the relationship between the push direction of the push button switch provided on the side surface of the portable terminal and the push direction of the push button provided on the holder is substantially perpendicular. In this case, the terminal push button can be pushed in with a large pressing force when the push button is pushed in, without requiring a large push force when pressing the push button, and with a good pressing force when pushed.

  Hereinafter, an embodiment of a portable terminal holder of the present invention will be described with reference to the drawings.
