Abstract

A digital camera includes a rotary switch, a switching unit, and a switching unit. The switching unit switches between two states independently of a function other than functions assigned to the respective states of the rotary switch, the two states including a restricted state where rotation of the rotary switch is restricted with a clicking feel and a function of at least one of a shutter speed and an aperture as a function with discrete output values is related to the rotating operation of the rotary switch and a non-restricted state where rotation of the rotary switch is not restricted and a function of at least one of focusing, and a zoom magnification of a lens, and similar function as a function with continuous output values is related to the rotating operation of the rotary switch.

Claims

1. A digital camera, comprising:

a rotary switch,

a switching unit, and

a restricting member,

wherein;

a rotating operation of the rotary switch causes a control corresponding to first and second functions respectively assigned to two states selected by the switching unit;

a switching unit is configured to switch between two states, independently of a third function other than the first and second functions assigned to the respective states of the rotary switch, the two states including a restricted state and a non-restricted state;

in the restricted state,

the rotation of the rotary switch is restricted with a clicking feel, and

a function of at least one of a shutter speed and an aperture as the first function with discrete output values is related to the rotating operation of the rotary switch;

in the non-restricted state,

the rotation of the rotary switch is not restricted, and

a function of at least one of focusing, and a zoom magnification of a lens, as the second function with continuous output values, is related to the rotating operation of the rotary switch; and

a restricting member configured to restrict rotation of the rotary switch in a case where the restricted state is set by the switching unit.

2. The digital camera according to claim 1, wherein

the rotary switch has a surface with a plurality of depressed portions or trough portions, and the restricting member engages with the depressed portion or the trough portion of the rotary switch in a case where the restricted state is set by the switching unit so as to restrict rotation of the rotary switch.

3. The digital camera according to claim 2, wherein

when the non-restricted state and the restricted state are switched by the switching unit, the digital camera holds a last output value in an original state before the switching.

4. The digital camera according to claim 2, wherein

the switching unit is configured to electrically control the restricting member.

5. The digital camera according to claim 2, wherein

the rotary switch is disposed in a peripheral area of a lens-barrel while having a rotary ring shape.

6. The digital camera according to claim 2, wherein

the switching unit enables switching from an operation setting screen.

7. The digital camera according to claim 2, wherein

the switching unit is configured to perform switching by an operation of pressing the rotary switch into a chassis side or pulling the rotary switch.

8. The digital camera according to claim 2, wherein

The depressed portion or the trough portion is disposed at least in a vicinity of an end portion of an outer periphery or an inner periphery of the rotary switch.

9. The digital camera according to claim 2, further comprising:

a selector switch disposed in a portion close to a shutter with respect to a lens center on a surface of the digital camera;

a fixed portion disposed inside the digital camera, the fixed portion being configured to move the restricting member in a direction to engage with the depressed portion or the trough portion in conjunction with a switching operation of the selector switch; and

a spring that is pressed by the fixed portion such that the restricting member engages with the depressed portion or the trough portion in the restricted state.
