The present invention relates to a lever mechanism disposed at an edge.

  Electronic devices used in the field of information processing and communication are required to have increased processing capacity and multi-functionality in order to meet various demands, and electronic circuit packages stored in electronic devices are also diverse. Therefore, it is necessary to mount various parts corresponding to this on the outer edge of the electronic circuit package.

JP-A-6-29678

  In an electronic device that stores a rectangular parallelepiped or a plate-like component typified by a plurality of electronic circuit packages, the component is stored in the device by operating a lever mechanism arranged at a corner edge of the component. In the conventional lever mechanism used when inserting and removing parts, the rotation area of the lever limits the mounting of the parts on the outer edge where the lever of the parts is placed, so the dimensions in the width direction of the parts must be increased. There is a problem of being.

  In order to alleviate the limitation of component mounting due to the lever length, for example, Patent Document 1 discloses that a mechanism for increasing the lever length when operating the lever of the electronic circuit package is provided. However, this method requires a mechanism for extending and retracting the lever, which increases the number of parts.

  In addition, when the operation of mechanically storing the part normally in the electronic device is completed, conventionally, after the part is stored by lever operation, a separate confirmation switch is manually turned on or off, or the storage process is performed. Since the storage completion instruction is input from the terminal, there is a possibility that the storage completion and the completion display of the part may be inconsistent due to leakage of the switch operation or the like.

  An object of the present invention is to provide a novel lever mechanism for solving the above-described problems related to the limitation of component mounting and the problem related to the display of the completion of component storage.

The purpose mentioned above is
(1) It is a lever mechanism that is arranged at the corner edge of a rectangular parallelepiped or plate-like component and is used when the component is inserted into and removed from a shelf-like storage portion in the apparatus or a hole that is opened to store the component. The lever rotation shaft is formed on the edge of the part at the time of inserting, storing and holding the part into the shelf storage part of the part or the hole opened so that the part can be stored, Adopting a mechanism to move the lever in the L-shaped through groove to a different position, rotate the lever in the component insertion / extraction operation, and store and hold the lever in the component at the time of storing and holding,
(2) Further, it is achieved by adopting a mechanism that automatically turns on / off the storage / holding determination unit that leads to the storage / holding display of the parts and the processing instruction on the circuit provided in the apparatus by the movement of the lever.

  According to the present invention, when the electronic package is stored and held, the lever is housed in the electronic package section, and the lever does not become an obstacle to the space at the side edge of the electronic package where the lever is arranged. The dimensions in the width direction of the electronic package can be reduced as compared with the conventional case. Alternatively, the area where the parts can be mounted on the part is widened with the distance between the two levers as it is, and a larger number of parts can be mounted than before. Further, in the present invention, since there is no lever expansion / contraction mechanism, the number of parts constituting the lever can be reduced.

  In addition, since the lever automatically pushes the switch for storing determination only when the electronic package is completely stored, it is not necessary to operate a separate storage completion switch, It is possible to prevent malfunction on the electric circuit related to insertion / extraction of the electronic package.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

  First, a lever mechanism in one embodiment will be described.
