JPS5924020Y2 - memo holder - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a memo holder for a camera, and is particularly characterized in that the memo holder also serves as a light shielding plate for a finder eyepiece.

2. Description of the Related Art Conventionally, it has been widely used to provide a holding frame on the back cover of a camera into which a memo indicating the type of film used, etc. can be inserted.

This kind of memo holder is used by cutting off a part of the film's outer box and inserting a part with the film type written on it, but it is difficult to put in and take out the memo, especially when the memo is no longer used. It is difficult to take out.

On the other hand, in a TTL metering single-lens reflex camera, when taking pictures using the self-timer or remote control device, the incident light from the viewfinder eyepiece may reach the light-receiving element placed around the viewfinder, resulting in an exposure error. be.

In order to prevent such reverse incident light, some cameras are equipped with an eyepiece shutter that covers the eyepiece part within the finder cover of the camera, but the mechanism becomes complicated, and some cameras are attached to the outside of the viewfinder eyepiece frame. is also known, but it has drawbacks such as being easy to lose and difficult to operate.

In order to solve both of the above-mentioned drawbacks and make it easier to insert and take out notes, the present application provides a holding plate for holding memo paper, inserts it into a holding frame provided on the back cover of the camera, and attaches it to the holding plate. A portion of the lens is used to cover the viewfinder eyepiece.

The present invention will be explained in detail below with reference to the figures.

FIG. 1 shows the back of a single-lens reflex camera to which the present invention is applied.

In the figure, 1 is the back cover of the camera, 2 is the top cover, 3 is the bottom cover, and 4 is the finder eyepiece frame.

Reference numeral 5 denotes a memo holding frame similar to a conventional one, which is fixed to the back cover 1 of the camera with rivets or the like, so that a memo paper or the like can be inserted from the top.

A memo holding plate 6 is inserted into the holding frame 5 together with the memo paper 7, and is formed by bending an elastic thin plate of steel or phosphor bronze into the shape shown in FIG.

In FIG. 2, a portion 6a is a shielding portion to cover the eyepiece frame 4, and an upper portion 6b thereof is folded back to hold a memo sheet and also serves as a finger rest.

6C is a bent portion provided to sandwich the eyepiece frame 4, and 6d is a protrusion portion provided to fit into the eyepiece frame.

The lower part of the holding plate 6 is bent toward the back lid side at a bending line 6e,
Further, at its lower end, a bent portion 6f to the same side and a stopper 6g bent to the opposite side are provided.

A memo paper 7, such as a part of a film outer box, is placed between 6b and 6g, and inserted into the holding frame 5 while pressing the holding plate 6 against the back cover 1 against its elasticity, until it stops at the lower end. When you release your hand, the protrusions 6d, as shown in FIGS. 1 and 3,
The bent portion 6f is in contact with the surface of the back cover 1, and the elasticity of the holding plate holds the memo paper 7 pressed against the inner surface of the frame 5, so that it will not move accidentally.

When using a self-timer or photographing by remote control, when the head 6b is hooked with a finger and pulled upward, the memo sheet also moves upward and stops when the stopper 6g hits the edge 5a of the frame 5.

When the hand is released at this position, the projection 6d falls into the eyepiece frame 4 due to the elasticity of the holding plate, and the shielding portion 6a is held in pressure contact with the surface of the eyepiece frame 4 to completely shield the eyepiece from light.

This state is shown in FIG. When the holding plate 6 is pulled up, the bent portions 6C provided on both sides of the head sandwich the side surfaces of the eyepiece frame 4 to guide the holding plate 6 and prevent the shielding portion from shifting in the stopped state.

When the memo sheet is no longer needed, the finger rest can be taken out by pressing the holding plate against the back cover while pulling the part 6b upward.

According to the present invention, it is possible to easily insert and take out a memo having the above-described structure, and to obtain a memo holder that can prevent reverse incident light from the viewfinder with an extremely simple operation.

For cameras with an electronic self-timer circuit, a switch for switching between normal shooting and self-timer shooting is provided near the eyepiece frame, and the switch can be switched using an operation button that is linked to the movement of the holding plate. It is possible to simultaneously switch to and block light from the viewfinder eyepiece.

Claims (1)

[Scope of utility model registration request] A memo holding plate is inserted into a holding frame 5 fixed to the outer surface of the back cover of the camera, with a memo paper 7 sandwiched between a folded part 6b made of an elastic thin plate provided at the upper end and a bent part 6g provided at the lower end. 6, the memo holding plate has an upper part 6a bent toward the back lid side at a bending line 6e, a protrusion 6d toward the back lid side on the upper part, and a new bent leg portion 6f toward the back lid side on the lower end. When inserted into the holding frame, the protruding part 6d and the folding leg part 6f contact the outer surface of the back cover, and due to elasticity, the lower part of the folding line 6e holds the note paper 7 pressed against the inner surface of the holding frame. However, when the memo holding plate is pulled upward, the protrusion 6d fits into the viewfinder eyepiece frame, and the upper part 6a comes into pressure contact with the viewfinder eyepiece frame due to its elasticity, covering the viewfinder eyepiece and preventing light from entering the finder. A camera memo holder characterized by being held in a position that blocks the
