Description

  The present invention relates to an electronic imaging device, and more particularly to the structure of an electronic imaging device.

In recent years, in electronic imaging devices such as digital still cameras, designs such as thinness, smallness, luxury, etc. have been regarded as important in addition to functions and usability, and each company has also reduced the size of each internal component and the layout of each internal component. It is devised. Japanese Patent Application Laid-Open No. 2004-228561 discloses a technique for disposing a zoom motor between a strobe light emitter and an upper wall portion of a film winding chamber as a zoom motor disposition structure in a camera. Some of the layouts of recent digital still cameras include a configuration in which a strobe light emitting unit is disposed in front of a zoom motor.
JP 2000-66284 A

  In the above digital still camera configuration, when static pressure is applied to the strobe window, if the strobe light emitter itself is not rigid and cannot receive static pressure, it will indirectly stress the zoom motor and zooming operation There is a problem that abnormal noise occurs in some cases, and in some cases, the zooming operation is defective. In addition, with the downsizing and high density of the camera outer shape, the driving sound of the motor travels through the housing and is collected by the microphone.

  The strobe is also composed of a light emitting part having a light emitting tube, a reflector, etc., and an electric circuit part on which electric parts forming a light emitting circuit arranged in the vicinity of the light emitting part are mounted. A high voltage of several kV is generated from the secondary electrode of the trigger coil in order to cause the arc tube to emit light. In order to emit light, it is necessary to electrically connect to the above-mentioned reflector, and problems such as light emission omission due to electric leakage In order to prevent this, it is desirable to place a trigger coil in the vicinity of the light emitting part. However, the outer shape of the trigger coil itself is large, and electric leakage to the body of the zoom motor is considered, especially between the strobe light emitter and the zoom mechanism. It is difficult to place them.

  Similarly, in the arrangement structure of the stroboscopic light emitting unit and the zoom motor, when the push button is arranged immediately behind the stroboscopic light emitting unit, if the member receiving the force in the pressing direction of the push button has no rigidity, the member bends and the zoom motor This can cause stress on the screen and cause clicks to occur.

  The present invention has been made paying attention to the above points, and an object of the present invention is to provide an electronic imaging device that protects a lens barrel drive system in the electronic imaging device from external pressure without increasing the number of components.

  In an electronic imaging device equipped with an imaging optical system that drives a lens barrel with a drive motor, a strobe window and a strobe case that supports the same cover the surface facing the strobe window of the drive motor or a plurality of surfaces. And

  Further, the present invention is characterized in that a strobe case receives a trigger coil that generates a trigger voltage of a strobe circuit, and holds the strobe lead wire with an insulating cap member that covers the trigger coil.

  In addition, a strobe case holds the board on which the operation system switch is mounted.

  According to the present invention, there is no stress on the zoom motor even when static pressure is applied to the strobe window or when the push button is pressed, and the motor is covered by covering a plurality of surfaces of the zoom motor. The noise can be reduced without insulating the drive sound and increasing the number of components. In addition, by adding a trigger cap, which is also an insulating member, the trigger coil can be placed near the strobe light emitting section, and electrical leakage can be prevented more reliably, and at the same time, a digital still camera with a good click feeling of the operation button is provided. Things will be possible.

  Embodiments of an imaging apparatus according to the present invention will be described below in detail with reference to the accompanying drawings.

  An embodiment of the present invention will be described with reference to FIGS.

  In FIG. 1, reference numeral 1 denotes a digital still camera body. An imaging lens of an imaging optical system is incorporated in a front surface portion, and a telescopic lens barrel 2 is disposed, and a subject image is captured by the optical system disposed therein. An image is formed on the element. A finder window 3 is provided above 2, and a strobe light emitter 4 that emits light as necessary when the amount of light is insufficient at the time of photographing is provided at the upper right of the apparatus. On the left side of 2 is a side slide type barrier 6 that can slide along the front cover 5 made of an aluminum alloy, and covers and protects 2, 3, and 4 except during imaging.

  On the upper surface portion, the release button 7 for instructing the start of the imaging operation, and by this operation, the subject is imaged, and the image data of the subject image is recorded on a recording medium (not shown). Reference numeral 8 denotes a top base that holds the release button 7 and also serves as an external component. 9 is a rear cover of an aluminum alloy, and a side cover 10 of a resin part as a separate exterior member is disposed and fixed between 5 and 9.

  A liquid crystal display device (not shown) is provided on the rear surface portion, and is used for confirming a subject image to be captured and for reproducing and displaying the captured image. There are other operation buttons 11.

  FIG. 2 is an exploded perspective view of the exterior member and the strobe light emitter of the imaging apparatus according to the present invention. The zooming operation by expanding and contracting the lens barrel 2 transmits the rotational driving force of the zoom motor 12 to the zoom gear train 13. This is obtained by using a cam ring (not shown) of the lens barrel 2. The strobe light emitter is assembled so as to cover a part of the zoom motor 12 and the zoom gear train 13 from above and fixed to the main body, and the flexible printed circuit board 14 having the operation SW mounted on the back is fixed. Thereafter, the front cover 5 and the rear cover 9 made of aluminum alloy are assembled. The operation button 11 is bonded and fixed to the rear cover 9 in advance.

  A trigger coil 16 is disposed on the bottom side of the strobe case 15 and is fixed and insulated by a trigger cap 17. The trigger coil 16 has a trigger cable 17 and is led out of the strobe case by being regulated by a guide rib 15a and a trigger cap 17 provided in the strobe case.

  FIG. 4 is a schematic vertical sectional view around the strobe light emitter.

  The strobe case 15 has a gap between the zoom motor 12 and the zoom gear train 13 larger than the gap between the front cover 5 and the rear cover 9, so that the static pressure and the pressing by the push button are applied to the strobe window portion. The zoom gear train 13 is not transmitted. Further, by closing the gap between the strobe case 15 and the front cover, it is possible to reduce the amount of bending of the strobe case 15 which is also a receiving member in the pressing direction of the operation SW 14a mounted on the flexible printed circuit board 14, and the push button from the user It is possible to transmit the press to the operation SW 14a without loss, and the click feeling can be improved.
