Description

  The present invention relates to a housing structure of an apparatus such as an electronic device, and more particularly to an opening / closing structure of a sub-cover that covers a portion having a construction section inside such as a wiring section of a main apparatus.

  Conventionally, various device housing structures have been proposed. For example, an electronic device casing structure is known in which the cover of the electronic device can be easily attached and detached, and the installation work and maintenance inspection of the electronic device can be performed safely and quickly (see, for example, Patent Document 1). In the electronic device casing structure disclosed in Patent Document 1, the cover of the electronic device casing is divided into a main cover and a sub cover, and a projecting piece provided on the sub cover is provided as a structure for attaching the sub cover to the base. An engagement structure with a slit provided in the base is adopted. More specifically, the cover is composed of a main cover that is not removed in principle and a sub-cover that may be removed. The sub cover is mounted on the base by providing protrusions on both side surfaces of the sub cover, slits provided on both side surfaces of the base, holes provided on the front surface of the sub cover, and on the front surface of the base. This is done by tightening the screw through the hole.

  There is also known a housing structure of an electronic device in which a cover can be fixed to a case without using a set screw (see, for example, Patent Document 2). In the case structure of an electronic device disclosed in Patent Document 2, a case that houses an electronic component unit includes a case that opens on one side, a main cover that covers the opening of the case, and a sub-cover that covers a battery housing. And more. The main cover is slid with respect to the case, and the one end side of the main cover is locked by engaging the protrusion of the main cover with the groove provided in the case. Further, the main case slide is locked by press-fitting a locking portion provided on the other end side of the main cover into a notch on the case side. The sub cover is locked with respect to the case by sliding the sub cover with respect to the case and engaging the protrusion of the sub cover with the groove of the case. At the same time, the slide of the sub cover is locked by locking the main cover sub cover.

  Furthermore, in the case of a line printer housing composed of a pedestal part and an exterior cover, it is easy to attach even a relatively large integrated cover while enhancing the soundproofing effect of the engaging part between the pedestal part and the exterior cover. A method of attaching a cover that can be easily removed is known (see, for example, Patent Document 3). In Patent Document 3, guide rails are provided on the left and right of the upper portion of the pedestal portion, and the exterior cover includes two longitudinal engaging portions that can slide along the guide rails. The soundproofing effect is enhanced by the airtightness of the engaging part by the guide rail provided on the left and right of the pedestal part and the sliding when the exterior cover is attached. In addition, positioning at the time of mounting is not required by the engaging portion and the fixing screw of the outer cover, and handling of the outer cover is facilitated in combination with the guide rail.

  Further, a lock mechanism that can fix a member to be locked to the lock member main body by a pressing operation is known (for example, see Patent Document 4). The lock mechanism disclosed in Patent Document 4 has an engagement means provided on the lock member main body and a lock means. When the engaged portion of the member to be locked is set at a predetermined position, the engaging means has a posture capable of engaging with the engaged portion, and engages with the engaged portion by a pressing operation. The locking means locks the engaging means in a state where the engaging means is engaged with the engaged means.

  The electronic device may be a main device such as a key telephone device. The main device is used by being installed on the floor or installed at a high place in the room. When the main apparatus is installed on the floor, it is easier for the operator to perform the work by removing the sub cover. On the other hand, when installing the main apparatus at a high place, it is easier for the operator to perform the work if the sub-cover can be fixed in an open state.

  However, conventionally, as disclosed in Patent Document 1 described above, the sub-cover that covers the construction portion of the main apparatus is fixed to the apparatus main body with screws in the closed state.

  Therefore, a tool is required to open the sub cover during construction. In addition, it is necessary to store the removed fixing screws until the construction is completed. Furthermore, it is necessary to store the sub-cover removed during the construction until the completion of the construction. For this reason, when construction is performed at a high place or the like, it is necessary to perform an extra operation such as temporarily placing the sub cover in a place (low place) that does not interfere with the construction, resulting in poor workability.

  In addition, even when the sub cover can be fixed to the apparatus main body in an open state, it is generally fixed by another part such as a support bar. Therefore, it is disadvantageous in terms of workability, manufacturability, and cost.

  In Patent Document 2, the main cover and the sub cover can be attached to the case without using a set screw. However, in the structure of Patent Document 2, the sub-cover can only be attached to and detached from the case, and the sub-cover cannot be fixed to the case in an open state.

  The cited document 3 only discloses a case of a line printer in which the exterior cover is slidable with respect to the pedestal portion, and the exterior cover is attached to the pedestal portion with fixing screws. Therefore, it has the same problem as that of Patent Document 1 described above.

  The cited document 4 only discloses a lock mechanism that can fix the member to be locked to the lock member main body. In other words, the cited document 4 only discloses a lock mechanism that locks the locked state in a state where the locked member is closed with respect to the lock member main body, and the locked member main body is locked. There is no disclosure or suggestion of a lock mechanism that locks the open state in a state in which it is opened.

  Accordingly, an object of the present invention is to provide a housing structure of an apparatus that can not only lock a sub-cover in a closed state but also lock the sub-cover in an opened state.

  Another object of the present invention is to provide a housing structure of an apparatus in which a sub cover can be removed.

  Still another object of the present invention is to provide a housing structure of an apparatus that can realize the above-described lock operation and removal operation of a sub-cover without using separate parts such as screws and support bars.

  A specific object of the present invention is to provide a sub-cover opening / closing structure in which the sub-cover covering the construction part can be fixed to the main apparatus in an open state with only a single component and with a simple structure. That is.

According to the present invention, there is provided a housing structure of a device including a main cover and a sub cover that cover the device main body, and an opening / closing mechanism that allows the sub cover to be opened and closed with respect to the device main body, a first locking means for locking the closed state in a state of closing the sub cover Te, e Preparations and second locking means for locking the open state in the open state of the sub-cover with respect to the apparatus main body, and The second locking means provides a housing structure of the device that includes a main claw that extends upward from the upper end of the sub-cover and an insertion hole that is provided in the device main body and into which the main claw is inserted. .

  The housing structure of the apparatus according to the present invention includes a first locking means for locking the closed state when the sub cover is closed with respect to the apparatus main body, and an open state when the sub cover is opened with respect to the apparatus main body. By adopting a structure including a second locking means for locking the sub cover, the sub cover can be fixed to the apparatus main body without using a screw in the closed state, and the sub cover can be attached to the apparatus main body without using a screw even when opened. The cover can be fixed in an open state.
