Although the board is formed in a size approximately the same as the size of the main unit, the main unit cover or the battery compartment may be removed when mounting with the fixing unit. After the fixing means installation portion was exposed, it was necessary to attach using the fixing means. For this reason, it takes time to mount and fix, and it also takes time to restore the main body cover and the battery housing after the mounting. Further, there is a possibility that sufficient fixing strength cannot be achieved by fixing with fixing means such as screws.

In addition, for example, the striker attached to the door frame side is provided with an engagement hole through which the shaft is inserted in order to engage with the shaft advancing from the main body device and achieve the door lock state. Since the hole is provided only in one place (in one direction), the striker hole is accurately positioned with respect to the main body device, more specifically, with respect to the advance / retreat position of the shaft from the main body device. The striker must be fixed afterwards. Depending on the shape of the door frame on which the striker is fixed, it may be difficult to install the striker at the desired position or posture. In such a case, the striker must be re-installed together with the main unit. . Therefore, it takes time for installation and there is a possibility that the installation location is limited.
