It is desirable that the status can be clearly displayed.

If the operation means can be selectively assigned a lighting operation function of the information display means and another operation function (for example, a light emission operation function of a strobe light emitting means), the illumination of the information display means can be performed. It is possible to reduce the number of operation means necessary for operations and other operations, and it is possible to easily perform these operations in a dark place.

In this case, the emission color of the status display light emitting means is switched in accordance with the operation function assigned to the operation means, and the light emission of the status display light emission means is turned off in accordance with the light emission enable / disable state of the strobe light emission means. ,lighting blinking,
