Abstract

PURPOSE:To prevent water which drops when a cover is opened from permeating into an opening part by gathering inserting and taking out a video cassette and a battery, and a signal input/output terminal part, a video operation switch part in the opening part respectively and constructing a projected line provided in the periphery of the opening part in a gutter. CONSTITUTION:The projected line 26 formed in the periphery of the opening part 21 is abutted on a packing 27 when the cover 5 is closed and it is digged into the packing 27 when cover clamping claws 28a and 28b clamp the cover 5 with a case mainbody 3 so as to realize the watertight structure of a case 2. Furthermore, the projected line 26 makes watertight structure, catches dropping dust and waterdrop at the upper part of the cover 5 when the cover 5 is opened, makes them to flow to the periphery of the opening part 21 and prevents them from permeating into the opening part 21.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a VTR-integrated camera, and particularly to a casing suitable for preventing dust, moisture, or moisture from entering the camera body.

[Conventional technology]

Conventional VTR-integrated cameras have gaps in the case's video cassette insertion slot, battery mounting area, signal input/output terminal area, and each operation switch area, so dust, moist air, water droplets, etc. can enter the inside of the case. However, there were many limitations such as damage to the magnetic head or tape, condensation on the cylinder, and the inability to use it in the rain.

In order to solve the above problems, a VTR-integrated camera with an airtight seal between each unit of the case and improved watertightness was developed.
It is disclosed in Japanese Patent No. 220982.

[Problem to be solved by the invention]

In the conventional technique disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 1-220982, the case is opened in two parts, and therefore an inner case is required to cover the camera section and the video deck section inside the case.

The purpose of the present invention is to solve the problems of the prior art described above,
To provide a VTR-integrated camera which eliminates the need for an inner case, has a simple configuration, and has a casing with improved watertightness.

[Means to solve the problem]

In order to solve the above problems, in the present invention, an opening is formed in a part of the side surface of the housing, a battery and a video cassette are inserted into and taken out from the opening, and a recording and playback switch of the video section is inserted into the opening. A signal input/output terminal is provided.

[Effect]

The insertion and removal of the video cassette and battery, as well as the signal input/output terminal section and the video operation switch section are gathered in the opening, and the opening is made a part of the side surface of the case, so the other parts of the side surface of the case can be replaced with the above conventional technology. Serves as a disclosed medium case.

The protruding stripes provided around the opening form a rain gutter structure and prevent water that falls when the lid is opened from entering the opening.

and the lid clamp claw slide lever 42a are integrally formed. Lid clamp claw slide shaft 42b and housing body 3
An O-ring 41 is press-fitted between the lid clamp claw slide shaft 42b and a watertight structure of the lid clamp claw slide shaft 42b. A fixing claw 43 is fixed to the housing body 3, and a lid clamping claw 28
Tighten and seal the lid 5. When the lid opening/closing knob 16 is turned, the lid clamp claw slide lever 42a rotates and the lid clamp claw 28 is slid. The lid clamp claw 28 is disengaged from the fixed claw 43, and the lid 5 is opened and closed.

FIG. 7 is a sectional view taken along the line C-- in FIG. 2. A camera section 6 is placed inside the housing 2, and a waterproof glass 46 is arranged in front of the camera section 6, and a power switch 52 and a left-hand REC switch 55 are arranged behind the camera section 6. Furthermore, a macro lens 60 and its diopter adjustment dial 17 are arranged at the rear of the housing body 3.

An O-ring 47 is press-fitted between the waterproof glass 46 and the housing body 3, and the waterproof glass 46 is fixed to the housing body 3 with the waterproof glass ring 45. A thread is cut between the waterproof glass ring 45 and the housing body 30.

An O-ring 48 is press-fitted between the power switch lever 19 and the housing body 3, and an O-ring 48 is press-fitted between the power switch lever 19 and the left-hand R.
An O-ring 49 is also press-fitted between the EC button shaft 50 and the EC button shaft 50. The rear end of the power switch lever 19 is a rotary lever 51
The rotating lever 51 turns the power switch 52 ON and OFF. The left-handed REC button shaft 50 is urged toward the outside of the housing 2 by a spring 53, and is prevented from being removed by an E-ring 54. When the left-hand REC button is pressed against this biasing force, the tip of the left-hand REC button shaft 50 presses the left-hand RFC switch 55, and recording begins.

are formed and fit into grooves 73a and 73b spirally dug into the outer periphery of the macro lens case 72. Therefore,
When the lens drive ring 58 is rotated, the macro lens 60 moves in the axial direction according to the screw principle. Two protrusions 7 formed at paired points on the inner circumference of the lens drive ring 58
1a and 71b are shaped horizontal slits 77 formed at the rear end of the EVF case 56, one each on the upper and lower sides) The claws 78 formed at the rear end of the EVF case 56 are connected to the lens drive ring 5.
The number 8 is a stop.

The EVF case 56 is fixed to the housing body 3 with a screw portion 75. An O-ring 57 is press-fitted between the EVF case 56 and the housing body 3 to form a watertight structure.

A waterproof glass 59 is fixed to the front part of the EVF case 56, forming a watertight structure in this part.

An eyepiece 44 is fitted into the outside of the EVF case 56 to form a hood and prevent external light from entering between the eye and the macro lens 60.

The diopter adjustment dial 17 is rotatably supported on the housing body 3 by a dial shaft 66, a dial pulley 67 is fitted into the inside of the housing body 3 of the dial shaft 66, and is fixed to the dial shaft 66 with a screw 68. Ru. An O-ring 65 is press-fitted between the dial shaft 66 and the housing body 3 to form a watertight structure.

A relay pulley 61 is arranged between the dial pulley 67 and the lens drive ring 58, and the diopter adjustment dial 17
The rotation of the lens is transmitted to the lens drive ring 58. The relay pulley 61 is rotatably supported by a pulley shaft 62 installed in the housing body 3, and is prevented from being removed by an E ring 63.

〔Effect of the invention〕

Since the present invention is configured as described above, it produces the effects described below.

(1) Inserting and removing the video cassette and battery,
In addition, the signal input/output terminal section and the video operation switch section are gathered in the opening, and the opening is made a part of the side surface of the case, so that the other parts of the side surface of the case function as the inner case disclosed in the above-mentioned prior art. Therefore, there is no need to have a double structure for the case.

(2) The protruding stripes provided around the opening form a rain gutter structure,
This has the effect of preventing water that falls when the lid is carelessly opened from entering the opening.
