Abstract: The present invention provides an in-vehicle apparatus and a front panel which are of uncomplicated configuration and can improve usability. There is provided an in-vehicle apparatus that includes a reproduction apparatus main body to be mounted in a vehicle, and a front panel which is detachable with respect to the reproduction apparatus main body, the front panel including a first connecting unit that is connected to the reproduction apparatus main body, a memory that is connected to the first connecting unit, a second connecting unit that is connected to the memory, and is connected to a signal input/output apparatus, and a control unit that is arranged between the memory and the second connecting unit, and controls inputting and outputting of a signal in the second connecting unit with respect to the memory.

Abstract: A portable apparatus of the present invention comprises a first unit, a second unit, and a hinge device that is coupled to the first and second units such that the units can be moved to be in contact with or spaced apart from each other and allows relative sliding movement between the first and second units within a certain range. The hinge device exerts a force in a direction in which the first and second units are spaced apart from each other, through the relative sliding movement by a predetermined distance between the two units in the complete contact state of the first and second units.
